This invention relates to torque/speed transmissions, specifically to “new Cone Assemblies” and “new Torque Transmitting Members/Non-Torque Transmitting Members for previously disclosed Cone Assemblies” that can be used to construct previously disclosed Continuously Variable Transmissions (CVT's).
The Cone Assemblies or Cone Assembly of this disclosure are primarily for the CVT's described in U.S. Pat. Nos. 8,628,439; 9,651,123; 9,958,064; 9,964,209; and Int. App. PCT/US2020/023854 (pub. #: WO/2020/198007). The Cone Assemblies of this disclosure are mainly new configurations for a “Cone with One Torque Transmitting Member”; but the Cone Assemblies of this disclosure can also be used to construct a “Cone with Two Opposite Torque Transmitting Members”, by replacing the Non-Torque Transmitting Member of a “Cone with One Torque Transmitting Member” with another Torque Transmitting Member.
Unless otherwise specified, the Torque Transmitting Members and Non-Torque Transmitting Members of this disclosure are primarily for a “Cone with One Torque Transmitting Member” described in U.S. Pat. No. 8,628,439, for which the Cone of the “Cone with One Torque Transmitting Member” described in U.S. Pat. No. 8,628,439 is replaced with a Cone of this disclosure. The Torque Transmitting Members of this closure can also be used to construct a “Cone with Two Opposite Torque Transmitting Members”, by replacing the Non-Torque Transmitting Member of a “Cone with One Torque Transmitting Member” with another Torque Transmitting Member.
A “Cone with One Torque Transmitting Member” of U.S. Pat. No. 8,628,439 (which is referred to as front pin belt cone assembly 520A in U.S. Pat. No. 8,628,439) is described in column 90 line 64 to column 99 line 11; and shown in FIGS. 91A, 91B, 92A, 92B, 93 to 101 of U.S. Pat. No. 8,628,439. All parts of the front pin belt cone assembly 520A, except for pin belt cone 540 are to be used for the Torque Transmitting Members and Non-Torque Transmitting Members of this disclosure; unless otherwise specified.
A “Cone with One Torque Transmitting Member” is basically a cone that has a “torque transmitting member” that is rotatably fixed relative to the surface of its cone, but can slide axially relative to the surface of its cone. The “torque transmitting member” is used for torque transmission and can be made toothed. Preferably (although not absolutely necessary), a “Cone with One Torque Transmitting Member” also has a “non-torque transmitting member”, which is primarily used to maintain the alignment of the transmission belt of its cone and balance-out the centrifugal forces of the “torque transmitting member”. For the “Cone with One Torque Transmitting Member” of U.S. Pat. No. 8,628,439, which is referenced in the previous paragraph, the a “torque transmitting member” is labeled as “pin belt torque transmitting member 590” and the “non-torque transmitting member” is labeled as “pin belt non-torque transmitting member 690”. This disclosure also describes new configurations for a “Cone with One Torque Transmitting Member”.
An example of a CVT that can be constructed out of two “Cone with One Torque Transmitting Member”, which are labeled as Cone 1A and Cone 1B, is shown in
Cones 1A and 1B are each a “Cone with One Torque Transmitting Member”. Cone 1A has a Torque Transmitting Member 1A-M1, Non-Torque Transmitting Member 1A-M2, and a Leveling Loop 1A-M3. Cone 1B has a Torque Transmitting Member 1B-M1, Non-torque Transmitting Member 1B-M2, and a Leveling Loop 1B-M3. Torque transmitting members 1A-M1 and 1B-M1 have teeth so that toothed torque transmission can be used, although friction torque transmitting members can also be used.
A leveling loop, such as Leveling Loop 1A-M3 and Leveling Loop 1B-M3, is a flexible loop with a tapered bottom surface that provides a level top resting surface for a transmission belt. It is recommended that each leveling loop is made out of a low friction flexible material that can expand and contract accordingly with the expansion and contraction of its cone; otherwise the CVT needs to be configured so that the leveling loops do not get in the way as the transmission ratio of their CVT is changed.
Tensioning Pulley 3 acts as a support pulley and tensioning pulley. Tensioning Pulley 3 and Support Pulley 4 are mounted so that they can freely move sideways in the horizontal direction. And Tensioning Pulley 3 is pushed upwards in the vertical direction so that it can maintain proper tension in Transmission Belt 2 for all operating conditions of the CVT.
Listing of Prior Arts
In this disclosure, Cones, Cone Assemblies, Torque Transmitting Members, and Non-Torque Transmitting Members for “slightly modified commercially available” and “commercially available” Transmission Belts are described. Using a commercially available Transmission Belt instead of a custom Transmission Belt can significantly increase performance and reduce cost; so as to increase the viability of this CVT design for commercial use.
The Torque Transmitting Members and Non-Torque Transmitting Members described in the prior art (such as in U.S. Pat. No. 8,628,439) use a custom designed Transmission Belt in order to allow for the usage a Leveling Loop, which allows for a Level Resting Place for its Transmission Belt on the conical (tapered) surface of its Cone.
The Torque Transmitting Members and Non-Torque Transmitting Members of prior art do not allow for the usage of a commercially available Transmission Belt, which is a Transmission Belt for which the teeth of said Transmission Belt are shaped below the belt of said Transmission Belt.
For the Torque Transmitting Members and Non-Torque Transmitting Members of prior art, a Leveling Loop has to be positioned beneath the bottom surface of its Transmission Belt in order to provide a Level Resting Place for its Transmission Belt.
A Leveling Loop of fixed length has to be able sit on the surface of its Cone on sections of its Cone where it needs to provide a Level Resting Place, and expand-out from the surface of its Cone on sections of its Cone where it does not need to provide a Level Resting Place; as required when the Transmission Diameter of its Cone is decreased.
The Torque Transmitting Members of prior art allow for the usage of a Leveling Loop of fixed length; since their teeth, which are positioned on their side surfaces, will not prevent a Leveling Loop from expanding-out from the surface of its Cone. The teeth of the Torque Transmitting Member for a commercially available Transmission Belt will prevent a Leveling Loop from expanding-out from the surface of its Cone. Also, a Leveling Loop that stretches as required as the Transmission Diameter of its Cone is changed is undesirable, since this Leveling Loop will have a very small lateral stiffness, which is required in order to maintain the axial alignment and straightness of the Leveling Loop.
This disclosure describes Torque Transmitting Members and Non-Torque Transmitting Members for a commercially available Transmission Belt; which do not require a Leveling Loop (which purpose is to provide a Level Resting Place for its Transmission Belt on the surface of its Cone).
These Torque Transmitting Members and Non-Torque Transmitting Members each have a Leveling Extension and an Empty Middle Section. The Leveling Extensions have the same taper as the taper of their Cone; and the top surfaces of the Leveling Extensions are level so that they can provide a Level Resting Place their Transmission Belt on the surface of their Cones.
The Leveling Extension of a Torque Transmitting Member is inserted into the Empty Middle Section of its Non-Torque Transmitting Member or its oppositely positioned Torque Transmitting Member, from which it can telescope in-and-out as required when the Transmission Diameter of its Cone is changed. And the Leveling Extension of a Non-Torque Transmitting Member is inserted into the Empty Middle Section of its Torque Transmitting Member, from which it can telescope in-and-out as required when the Transmission Diameter of its Cone is changed.
This disclosure also describes new configurations of a Cone Assembly for a “Cone with One Torque Transmitting Member” and a “Cone with Two Opposite Torque Transmitting Members”, which are more economical and more efficient than the prior art. And innovative designs that allow for a “Torque Transmitting Member with teeth that have a bottom surfaces”, so as to increase the strength of the Torque Transmitting Member considerably and allow for the usage of an off-the-shelf commercially available Transmission Belt, which has not been accomplished in the prior art. The innovation of this disclosure will likely allow for a commercially viable non-friction dependent CVT; which has not been accomplished in the prior art.
For the reference numerals in this disclosure, if used, the label M(number) after a labeling, where (number) is a number, such as M2 for example, is used to label different members of a part that is grouped under one label. And if used, the label S(number) after a labeling, where (number) is a number, such as S2 for example, is used to label the different shapes of a part that is grouped under one label.
Furthermore, the same parts that are used in different location might have a different labeling letter after their reference numeral, or a different reference numeral altogether if this is helpful in describing the invention. If two parts have the same reference numeral then they are identical unless otherwise described.
Torque Transmitting Member and Non-Torque Transmitting Member for usage with a slightly modified commercially available Transmission Belt (
In this section, a Torque Transmitting Member for a “Cone with One Torque Transmitting Member” or a “Cone with Two Oppositely Positioned Torque Transmitting Members”, and a Non-Torque Transmitting Member for a “Cone with One Torque Transmitting Member”, are described. The items of this section can be used with a slightly modified commercially available Transmission Belt, which is described in this section.
The Torque Transmitting Member and Non-Torque Transmitting Member of this section are for a “Cone with One Torque Transmitting Member” described in U.S. Pat. No. 8,628,439 (which is referred to as front pin belt cone assembly 520A in U.S. Pat. No. 8,628,439); for which the Cone (labeled as pin belt cone 540 in U.S. Pat. No. 8,628,439) of the “Cone with One Torque Transmitting Member” described in U.S. Pat. No. 8,628,439 is replaced with a Cone that has the cuts of Cone 12 of this disclosure. The Torque Transmitting Member of this section can also be used to construct a “Cone with Two Opposite Torque Transmitting Members”, by replacing the Non-Torque Transmitting Member of a “Cone with One Torque Transmitting Member” with another Torque Transmitting Member.
The Transmission Belt to be used with the items of this section is shown in
Teeth 5-S1 are used for torque transmission; and Flanges 5-S2 are used to support Transmission Belt 5 where necessary. Unlike a Transmission Pulley, a Cone Assembly to be used with the items of this section might provide less resting surfaces for its Transmission Belt; in order to compensate for this, additional strengthening reinforcements (such as shear strength reinforcements, etc.) can be added to Transmission Belt 5 if required.
The Torque Transmitting Member of this section, which is labeled as Torque Transmitting Member 7 (see
Torque Transmitting Member Section 7-M1 has teeth that can engage with the teeth of Transmission Belt 5. The cross-section of Torque Transmitting Member Section 7-M1, except for its Trailing End has a Left Section, a Right Section, and a Top Section, such that an Empty Middle Section is formed. The cross-section of the Trailing End of Torque Transmitting Member Section 7-M1 is solid, so that it does not have an Empty Middle Section; this is because the cross-section of the Trailing End of Torque Transmitting Member Section 7-M1 needs a surface to which Leveling Extension 7-M2 can be attached; as described previously, Leveling Extension 7-M2 is attached to the Trailing End of Torque Transmitting Member Section 7-M1.
Said Top Section is shaped such that it has teeth that can engage with the teeth of Transmission Belt 5, and such that it can support Transmission Belt 5 when it is resting on it. And said Empty Middle Section is used for inserting a Leveling Extension of an oppositely positioned Torque Transmitting Member (another Leveling Extension 7-M2) or an oppositely positioned Non-Torque Transmitting Member (Leveling Extension 10-M2); in a manner such the Leveling Extension of an oppositely positioned Torque Transmitting Member/Non-Torque Transmitting Member is laterally positioned between said Left Section and said Right Section, and vertically positioned between the “surface of the Cone to which it is attached” and the bottom surface of said Top Section.
Note: In this disclosure the term “Trailing End” is synonymous with the term “Rear End”, and the term “Leading End” is synonymous with the term “Front End”. But, whether the “Leading End” of a Torque Transmitting Member or Non-Torque Transmitting Member is actually positioned in-front of its “Trailing End” based on the direction its Cone is rotating, depends on whether that Torque Transmitting Member or Non-Torque Transmitting Member is attached to a Driving Cone or to a Driven Cone. When a Torque Transmitting Member or Non-Torque Transmitting Member is attached to a Driven Cone, then the Trailing End of that Torque Transmitting Member or Non-Torque Transmitting Member is preferably positioned in front of its Leading End; in this case, the Torque Transmitting Member or Non-Torque Transmitting Member is simply mounted in-reverse.
Torque Transmitting Member Section 7-M1 comprises of an elongated elastomer part that has reinforcement plates and reinforcement wires.
A reinforcement plate for Torque Transmitting Member Section 7-M1, which is labeled as Reinforcement Plate 6, is shown in
Left Vertical Side 6-S4 and Right Vertical Side 6-S5 are connected by a Tooth 6-S1 through Tooth Ends 6-S2, which are shaped on the left-end and right-end of Tooth 6-S1.
Tooth 6-S1 is shaped like a beam that has Tooth Shaped Cavity, which does not have a bottom surface (see
Tooth Ends 6-S2 are basically end-walls that connect Tooth 6-S1 to Left Vertical Side 6-S4 and Right Vertical Side 6-S5; as such, Tooth Ends 6-S2 are solid so that they do not have said Tooth Shaped Cavity. Tooth Ends 6-S2 are used to provide resting surfaces for Flanges 5-S2 of said Transmission Belt 5.
Additionally, Left Vertical Side 6-S4 and Right Vertical Side 6-S5, each have a Hole 6-S3 for a Reinforcement Wire 8; said Holes 6-S3 should be vertically located so that the neutral-axis of Torque Transmitting Member Section 7-M1 vertically coincides with the neutral-axis of its Transmission Belt 5.
In order to attach a Torque Transmitting Member described in this section to a “Cone with One Torque Transmitting Member” of U.S. Pat. No. 8,628,439 that has a Cone that has the cuts of Cone 12 of this disclosure; a Leading End Reinforcement Plate 6A, a Trailing Sleeve Reinforcement Plate 6B, and a Trailing End Reinforcement Plate 6C are used. A Cone with One Torque Transmitting Member” of U.S. Pat. No. 8,628,439 is referred to as a front pin belt cone assembly 520A in U.S. Pat. No. 8,628,439 (refer to column 90 line 64 to column 99 line 11; and FIGS. 91A, 91B, 92A, 92B, 93 to 101 of U.S. Pat. No. 8,628,439).
Attachment Sleeves 6A-S1 and 6A-S2 are used to attach the Leading End of Torque Transmitting Member 7 to a torque transmitting member carriage 550A of a front pin belt cone assembly 520A of U.S. Pat. No. 8,628,439; using the same method the sleeves of the leading end of a pin belt torque transmitting member 590 are attached to its torque transmitting member carriage 550A in U.S. Pat. No. 8,628,439 (refer to column 90 line 63 to column 91 line 48 of U.S. Pat. No. 8,628,439).
The bottom end of Attachment Sleeve 6B-S1 has a Locking Ring Groove 6B-S2, which is used to secure Attachment Sleeve 6B-S1 to its cone by sliding a fastener such as a Dome Shaped Nut or a Ball Clamp (which is preferred) into Attachment Sleeve 6B-S1, and securing the fastener by inserting a Locking Ring into Locking Ring Groove 6B-S2 (refer to U.S. Pat. No. 8,628,439 for details).
Attachment Sleeve 6B-S1 is used to connect its Torque Transmitting Member to its Trailing End Slide; using the same method as the method used to connect the trailing end of a pin belt torque transmitting member 590 to its trailing end slide 565-S1, described in U.S. Pat. No. 8,628,439 (see FIGS. 91A, 91B, 92A, 92B, 93 to 99 of U.S. Pat. No. 8,628,439).
If necessary, for proper alignment of Attachment Sleeve 6B-S1 with Locking Ring Pin 6C-S3 in their Trailing End Cut (see paragraphs below for details); Attachment Sleeve 6B-S1 can be positioned behind or in-front of its Reinforcement Plate, or the length of Extender 6B-S3 can be adjusted accordingly.
A Tooth 6C-S1, which is shaped identically as Tooth 6-S1 of Reinforcement Plate 6, is fixed on top of Solid Middle Section 6C-S6. Like Tooth 6-S1, Tooth 6C-S1 also has two Tooth Ends, which are labeled as Tooth Ends 6C-S5 and are identical to Tooth Ends 6-S2.
Additionally, Left Vertical Raise 6C-S7 and Right Vertical Raise 6C-S8, each have a Hole 6C-S2 for a Reinforcement Wire 8; said Holes 6C-S2 should be vertically located so that the neutral-axis of Torque Transmitting Member Section 7-M1 vertically coincides with the neutral-axis of its Transmission Belt 5.
In addition, Trailing End Reinforcement Plate 6C also has a Locking Ring Pin 6C-S3, which is fixed to the bottom surface of Trailing End Reinforcement Plate 6C, preferably at the mid-width of the bottom surface of Trailing End Reinforcement Plate 6C. Locking Ring Pin 6C-S3 is used to secure the Trailing End of Transmitting Member Section 7-M1 to its cone by sliding a fastener such as a Dome Shaped Nut or a Ball Clamp (which is preferred) into Locking Ring Pin 6C-S3, and securing said fastener by inserting a Locking Ring into a Locking Ring Groove 6C-S4 of Locking Ring Pin 6C-S3 (refer to U.S. Pat. No. 8,628,439 for details).
Torque Transmitting Member 7 should be designed so that the “Locking Ring Pin 6C-S3 of Trailing End Reinforcement Plate 6C” and the “Attachment Sleeve of its Trailing Sleeve Reinforcement Plate (such as Attachment Sleeve 6B-S1, 6D-S1 or 6E-S1)” can slide in the same Trailing End Cut of their cone; in a manner so that Locking Ring Pin 6C-S3 engages with the front-surface of its Trailing End Cut, which is the surface of its Trailing End Cut that prevents Locking Ring Pin 6C-S3 from moving towards the Leading End of Torque Transmitting Member 7. The engagement of Locking Ring Pin 6C-S3 with the front-surface of its Trailing End Cut can be used to transfer Reverse Torque between Torque Transmitting Member 7 and its Cone. Reverse Torque is torque that pulls the Trailing End of Torque Transmitting Member 7 towards the Leading End of Torque Transmitting Member 7. If necessary, some movement/play between “Attachment Sleeve 6B-S1, 6D-S1 or 6E-S1” and its Trailing End Cut can be allowed. And if there are interferences between the fastener for Locking Ring Pin 6C-S3 and the fastener for “Attachment Sleeve 6B-S1, 6D-S1 or 6E-S1”, then it is not necessary to use the fastener for “Attachment Sleeve 6B-S1, 6D-S1 or 6E-S1”.
It is also preferable (but not necessarily) that-Locking Ring Pin 6C-S3 can engage with the rear-surface of its Trailing End Cut, which is the surface of its Trailing End Cut that prevents Locking Ring Pin 6C-S3 from moving away from the Leading End of Torque Transmitting Member 7.
Although this is not preferred, but if it is too impractical to place “Attachment Sleeve 6B-S1, 6D-S1 or 6E-S1” and Locking Ring Pin 6C-S3 in the same Trailing End Cut of their cone; then Locking Ring Pin 6C-S3 does not have to be used, so that it can removed from Trailing End Reinforcement Plate 6C. For this configuration, “Attachment Sleeve 6B-S1, 6D-S1 or 6E-S1” should be secured to its Cone using a fastener.
The Trailing End Cuts for a cone are shown and labeled as trailing end cuts 540-S6 in FIG. 112B of U.S. Pat. No. 8,628,439; and shown and labeled as Torque Transmitting Member Trailing End Cut 12-A2 and Non-Torque Transmitting Member Trailing End Cut 12-B2 in
The Leading End Cuts for a cone are shown and labeled as leading end cuts 540-S1 in FIG. 112B of U.S. Pat. No. 8,628,439; and shown and labeled as Torque Transmitting Member Leading End Cut 12-A1 and Non-Torque Transmitting Member Leading End Cut 12-B1 in
If a Cone uses one Torque Transmitting Member 7, then one Leading End Cut of said Cone is used for inserting Attachment Sleeves 6A-S1 and 6A-S2 of Leading End Reinforcement Plate 6A of that Torque Transmitting Member 7. And if a Cone uses two oppositely positioned Torque Transmitting Members 7, then both Leading End Cuts of said Cone are used for inserting Attachment Sleeves 6A-S1 and 6A-S2 of a Leading End Reinforcement Plate 6A of a Torque Transmitting Member 7. Here into each Leading End Cut, Attachment Sleeves 6A-S1 and 6A-S2 of a Leading End Reinforcement Plate 6A of a Torque Transmitting Member 7 are inserted.
The proper location of “Attachment Sleeve 6B-S1, 6D-S1 or 6E-S1” relative to Locking Ring Pin 6C-S3, as well as the shape and size of all cuts of a Cone can be determined through trial-and-error and experimentation (such as tracing for example).
Torque Transmitting Member 7 is shown in
When Torque Transmitting Member 7 is used as the Torque Transmitting Member of a Cone with One Torque Transmitting Member or a Cone with Two Opposite Torque Transmitting Members, an oppositely positioned Torque Transmitting Member/Non-Torque Transmitting Member is attached oppositely of Torque Transmitting Member 7 on its Cone. Empty Middle Section 7-M1-S5 of Torque Transmitting Member 7 is used for inserting a Leveling Extension of said oppositely positioned Torque Transmitting Member/Non-Torque Transmitting Member; in a manner such that said Leveling Extension of said oppositely positioned Torque Transmitting Member/Non-Torque Transmitting Member can enter and exit Torque Transmitting Member 7 as required during Transmission Diameter Change of its Cone.
When assembled on its Cone, Leveling Extension 7-M2 is inserted into the Empty Middle Section of said oppositely positioned Torque Transmitting Member/Non-Torque Transmitting Member in a manner such that it can enter and exit said oppositely positioned Torque Transmitting Member/Non-Torque Transmitting Member as required during Transmission Diameter Change of its Cone.
Depending on whether Torque Transmitting Member 7 is used as a Torque Transmitting Member of a Cone with One Torque Transmitting Member or a Cone with Two Opposite Torque Transmitting Members, said oppositely positioned Torque Transmitting Member/Non-Torque Transmitting Member is either another Torque Transmitting Member 7 or a Non-Torque Transmitting Member 10.
Torque Transmitting Member Section 7-M1 comprises of a Leading End Reinforcement Plate 6A, a Trailing Sleeve Reinforcement Plate 6B, a Trailing End Reinforcement Plate 6C, and several Reinforcement Plates 6 that are joined together by two Reinforcement Wires 8 and encased by elastomer members as shown in
Between all teeth of the reinforcement plates (which are Leading End Reinforcement Plate 6A, Trailing Sleeve Reinforcement Plate 6B, Trailing End Reinforcement Plate 6C, and the Reinforcement Plates 6), an elastomer Belt Resting Section 7-M1-S1 is fixed (see
It is recommended that Teeth 5-S1 of Transmission Belt 5 can fully enter the teeth their Torque Transmitting Member Section 7-M1 (which are Teeth 6-S1 and 6C-S1). Through this engagement, the teeth of Torque Transmitting Member Section 7-M1 will also support Transmission Belt 5; so that if desired, Belt Resting Sections 7-M1-S1 can be omitted; but this is not preferred, since Belt Resting Sections 7-M1-S1 increase the lateral stiffness of Torque Transmitting Member Section 7-M1. Ideally, Torque Transmitting Member Section 7-M1 should be shaped/dimensioned such that Teeth 5-S1 that can fully enter into the teeth their Torque Transmitting Member Section 7-M1.
A partial cross-section of Torque Transmitting Member Section 7-M1 as cut as shown in
Here Left Elastomer Member 7-M1-S2 joins the left sides (as seen from the rear) of Leading End Reinforcement Plate 6A, Reinforcement Plates 6, said Trailing Sleeve Reinforcement Plate 6B, and Trailing End Reinforcement Plate 6C along the length of Torque Transmitting Member Section 7-M1; so as to form said Left Section of Torque Transmitting Member Section 7-M1. And Right Elastomer Member 7-M1-S3 joins the right sides of Leading End Reinforcement Plate 6A, Reinforcement Plates 6, said Trailing Sleeve Reinforcement Plate 6B, and Trailing End Reinforcement Plate 6C along the length of Torque Transmitting Member Section 7-M1; so as to form said Right Section of Torque Transmitting Member Section 7-M1.
Left Elastomer Member 7-M1-S2 and Right Elastomer Member 7-M1-S3, which are shown in hatching in
The rear-end (also referred to as the Trailing End) of Torque Transmitting Member Section 7-M1, which is shown as a sectional-view in
A rear-view of Leveling Extension 7-M2 is shown in
Leveling Extension 7-M2 has a Locking Ring Pin 7-M2-S1 (see
The Non-Torque Transmitting Member of this section, which is labeled as Non-Torque Transmitting Member 10 (see
Non-Torque Transmitting Member Section 10-M1 has two elastomer side members that are joined at its Leading End and its Trailing End (see
A Reinforcement Plate 9-M1 and a Reinforcement Plate 9-M2 are shown in
A Reinforcement Plate 9-M1 has a Hole 9-M1-S1, and a Reinforcement Plate 9-M2 has a Hole 9-M2-S1. These holes are for the reinforcement wires of Non-Torque Transmitting Member 10; and these holes should be located so that the neutral-axis of Non-Torque Transmitting Member 10 coincides with the neutral-axis of its Transmission Belt, which is Transmission Belt 5.
A Reinforcement Plate 9-M1 also has a Rail Reinforcement 9-M1-S2, and a Reinforcement Plate 9-M2 also has a Rail Reinforcement 9-M2-S2 (see
In addition, in order to prevent excessive vibration due to centrifugal forces, it is recommended that each “Reinforcement Plate Pair” and each “Reinforcement Plate” of a Non-Torque Transmitting Member 10 has the same weight as its corresponding (oppositely positioned on its cone) Reinforcement Plate of Torque Transmitting Member 7; so that the centrifugal forces of Non-Torque Transmitting Member 10 and Torque Transmitting Member 7 cancel each other out. For this purpose, a Reinforcement Plate 9-M1 also has a Balancing Weight 9-M1-S3, and a Reinforcement Plate 9-M2 also has a Balancing Weight 9-M2-S3 (see
Leading End Reinforcement Plate 9A is shown in
An Attachment Sleeve 9A-S2 is attached to Left Vertical Side 9A-S7; and an Attachment Sleeve 9A-S3 is attached to Right Vertical Side 9A-S8.
Attachment Sleeve 9A-S2 and Attachment Sleeve 9A-S3 are used to attach the Leading End of Non-Torque Transmitting Member 10 to a torque transmitting member carriage 550A of a front pin belt cone assembly 520A of U.S. Pat. No. 8,628,439; using the same method through which the sleeves of the leading end of a pin belt torque transmitting member 590 are attached to its torque transmitting member carriage 550A in U.S. Pat. No. 8,628,439 (refer to column 90 line 63 to column 91 line 48 of U.S. Pat. No. 8,628,439).
Leading End Reinforcement Plate 9A also has two Holes 9A-S4; these holes are for the reinforcement wires of Non-Torque Transmitting Member 10; these holes should be located so that the neutral-axis of Non-Torque Transmitting Member 10 coincides with the neutral-axis of its transmission belt, which is Transmission Belt 5.
Leading End Reinforcement Plate 9A also has two Rail Reinforcements 9A-S5. One Rail Reinforcement 9A-S5 is attached to Left Vertical Side 9A-S7, and the other Rail Reinforcement 9A-S5 is attached to Right Vertical Side 9A-S8. The Rail Reinforcement 9A-S5 that is attached to Left Vertical Side 9A-S7 has the same purpose as Rail Reinforcement 9-M1-S2 of Reinforcement Plate 9-M1; and the Rail Reinforcement 9A-S5 that is attached to Right Vertical Side 9A-S8 has the same purpose as Rail Reinforcement 9-M2-S2 of Reinforcement Plate 9-M2.
In addition, in order to prevent excessive vibration due to centrifugal forces, it is recommended that each “Reinforcement Plate Pair” and each “Reinforcement Plate” of a Non-Torque Transmitting Member 10 has the same weight as its corresponding (oppositely positioned on its cone) Reinforcement Plate of Torque Transmitting Member 7; so that the centrifugal forces of Non-Torque Transmitting Member 10 and Torque Transmitting Member 7 cancel each other out. For this purpose Leading End Reinforcement Plate 9A also has a Balancing Weights 9A-S6. These Balancing Weights are not necessary if other means for balancing the weight of the Reinforcement Plates are used; such as through the selection of material, adjusting the thickness of the plates, etc.
Attachment Sleeve 9B-S1 is used to connect its Non-Torque Transmitting Member to its Trailing End Slide; using the same method as the method used to connect the trailing end of a pin belt torque transmitting member 590 to its trailing end slide 565-S1, described in U.S. Pat. No. 8,628,439 (see FIGS. 91A, 91B, 92A, 92B, 93 to 99 of U.S. Pat. No. 8,628,439). If necessary, for proper alignment of Attachment Sleeve 9B-S1 with Locking Ring Pin 9C-S3 in their Trailing End Cut (see paragraphs below for details); Attachment Sleeve 9B-S1 can be positioned behind or in-front of its Reinforcement Plate in the same manner as Attachment Sleeve 6B-S1 can be positioned behind or in-front of its Reinforcement Plate (see
Trailing End Reinforcement Plate 9C also has two Holes 9C-S2, one on each side of Cut-out Section 9C-S1; these holes are for the reinforcement wires of Non-Torque Transmitting Member Section 10-M1; these holes should be located so that the neutral-axis of Non-Torque Transmitting Member Section 10-M1 vertically coincides with the neutral-axis of its Transmission Belt 5.
In addition, Trailing End Reinforcement Plate 9C also has a Locking Ring Pin 9C-S3, which is fixed to the bottom surface of Trailing End Reinforcement Plate 9C, preferably at the mid-width of the bottom surface of Trailing End Reinforcement Plate 9C. Locking Ring Pin 9C-S3 is used to secure the Trailing End of Non-Transmitting Member Section 10-M1 to its cone by sliding a fastener such as a Dome Shaped Nut or a Ball Clamp (which is preferred) into Locking Ring Pin 9C-S3, and securing said fastener by inserting a Locking Ring into a Locking Ring Groove 9C-S6 of Locking Ring Pin 6C-S3 (refer to U.S. Pat. No. 8,628,439 for details).
In addition, in order to prevent excessive vibration due to centrifugal forces, it is recommended that each “Reinforcement Plate Pair” and each “Reinforcement Plate” of a Non-Torque Transmitting Member 10 has the same weight as its corresponding (oppositely positioned on its cone) Reinforcement Plate of Torque Transmitting Member 7; so that the centrifugal forces of Non-Torque Transmitting Member 10 and Torque Transmitting Member 7 cancel each other out. For this purpose Trailing End Reinforcement Plate 9C also has a two Balancing Weights 9C-S4, one on each side of Cut-out Section 9C-S1. These Balancing Weights are not necessary if other means for balancing the weight of the Reinforcement Plates are used; such as through the selection of material, adjusting the thickness of the plates, etc.
Preferably, in order to keep Non-Torque Transmitting Member 10 tightly secured to its cone; Non-Torque Transmitting Member 10 is designed so that “Locking Ring Pin 9C-S3 of Trailing End Reinforcement Plate 9C” and “Attachment Sleeve 9B-S1 of Trailing Sleeve Reinforcement Plate 9B” can slide in the same Trailing End Cut of their cone, in a manner so that Locking Ring Pin 9C-S3 engages with the front-surface of its Trailing End Cut, which is the surface of its Trailing End Cut that prevents Locking Ring Pin 9C-S3 from moving towards the Leading End of Non-Torque Transmitting Member 10. And if there are interferences between the fastener for Locking Ring Pin 9C-S3 and the fastener for Attachment Sleeve 9B-S1, then it is not necessary to use the fastener for Attachment Sleeve 9B-S1.
It is also preferable (but not necessarily) that-Locking Ring Pin 9C-S3 can engage with the rear-surface of its Trailing End Cut, which is the surface of its Trailing End Cut that prevents Locking Ring Pin 9C-S3 from moving away from the Leading End of Non-Torque Transmitting Member 10.
Although this is not preferred, but if it is too impractical to place Attachment Sleeve 9B-S1 and Locking Ring Pin 9C-S3 in the same Trailing End Cut of their cone; then Locking Ring Pin 9C-S3 does not have to be used, so that it can removed from Trailing End Reinforcement Plate 9C. For this configuration, Attachment Sleeve 9B-S1 should be secured to its cone using a fastener.
The proper location of Attachment Sleeve 9B-S1 relative to Locking Ring Pin 9C-S3 as well as the shape and size of all cuts of their cone can be determined through trial-and-error and experimentation (such as tracing for example).

In its assembled state, Leveling Extension 10-M2 is inserted into the Empty Middle Section 7-M1-S5 of Torque Transmitting Member Section 7-M1 (see

For Torque Transmitting Member 7, Cone 12 has the following cuts (see
For Non-Torque Transmitting Member 10, Cone 12 (see
The cuts shown in
Somebody skilled in the art should be able to determine the accurate shape of the cuts through tracing, mathematics, etc.
Torque Transmitting Member with Teeth have a Bottom Surface (Base) (
In this section, a Torque Transmitting Member for a “Cone with One Torque Transmitting Member” or a “Cone with Two Oppositely Positioned Torque Transmitting Members”, for which its Teeth have a bottom surface (Base) is described. The Torque Transmitting Member of this section, which is labeled as Torque Transmitting Member 19 is basically identical to Torque Transmitting Member 7, except that its Teeth have a bottom surface or Base.
Torque Transmitting Member 19 is for a “Cone with One Torque Transmitting Member” described in U.S. Pat. No. 8,628,439 (which is referred to as front pin belt cone assembly 520A in U.S. Pat. No. 8,628,439); for which the Cone (labeled as pin belt cone 540 in U.S. Pat. No. 8,628,439) of the “Cone with One Torque Transmitting Member” described in U.S. Pat. No. 8,628,439 is replaced with a Cone that has the cuts and additional features of Cone 26 described in the “Cone with Leveling Extension Raising Sheets” section below. The Torque Transmitting Member of this section can also be used to construct a “Cone with Two Opposite Torque Transmitting Members”, by replacing the Non-Torque Transmitting Member of a “Cone with One Torque Transmitting Member” with another Torque Transmitting Member.
Torque Transmitting Member 19 can be used with a regular commercially available Transmission Belt, such as Transmission Belt 14. Transmission Belt 14, which comprises of Belt 14-S1 on which Teeth 14-S2 are shaped on the bottom surface of Belt 14-S1, is shown in
Torque Transmitting Member 19 is shown in
Torque Transmitting Member Section 19-M1 has teeth that can engage with the teeth of its Transmission Belt. The cross-section of Torque Transmitting Member Section 19-M1, except for its Trailing End has a Left Section, a Right Section, and a Top Section, such that an Empty Middle Section is formed. The cross-section of the Trailing End of Torque Transmitting Member Section 19-M1 is solid, so that it does not have an Empty Middle Section; this is because the cross-section of the Trailing End of Torque Transmitting Member Section 19-M1 needs a surface to which Leveling Extension 19-M2 can be attached; as described previously, Leveling Extension 19-M2 is attached to the Trailing End of Torque Transmitting Member Section 19-M1.
Said Top Section is shaped such that it has teeth that can engage with the teeth of its Transmission Belt, and such that it can support its Transmission Belt 14 when it is resting on it. And said Empty Middle Section is used for inserting a Leveling Extension of an oppositely positioned Torque Transmitting Member (another Leveling Extension 19-M2) or an oppositely positioned Non-Torque Transmitting Member (Leveling Extension 23-M2); in a manner such the Leveling Extension of an oppositely positioned Torque Transmitting Member/Non-Torque Transmitting Member is laterally positioned between said Left Section and said Right Section, and vertically positioned between the “surface of the Cone to which it is attached” and the bottom surface of said Top Section.
Torque Transmitting Member Section 19-M1 comprises of reinforcement plates that are held together by reinforcement wires and elastomer members.
A Reinforcement Plate for Torque Transmitting Member 19 is shown in
Reinforcement Plate 13 is basically identical to Reinforcement Plate 6 of Torque Transmitting Member 7, except that it has a Base. Reinforcement Plate 13 is preferred over Reinforcement Plate 6, since its Base will increase the strength of its tooth considerably. The problem with having a Base is that because the Base has some thickness, “the top surface of its Leveling Extension (which is positioned beneath said Base)” and “the bottom surface of the tooth of its Reinforcement Plate” will have different heights. And since both surfaces are used to provide a resting base for the bottom surfaces of the teeth of their Transmission Belt, here the bottom surfaces of the teeth of their Transmission Belt will be resting on surfaces of different heights. This problem is addressed in the “Cone with Leveling Extension Raising Sheets” and “Cone with Leveling Extension Raising Surfaces” sections below.
Reinforcement Plate 13 is shown in
Shaped to the left and right of Tooth 13-S3 are Tooth Ends 13-S6. Tooth Ends 13-S6 can be used to provide a resting base for the flanges of a Transmission Belt that has flanges, such as Transmission Belt 5.
The empty space between Left Leg 13-S1 and Right Leg 13-S2 (which is located below Base 13-S4) forms the Empty Middle Section of Torque Transmitting Member 19-M1; it is used for the insertion of a Leveling Extension of an opposite positioned Torque Transmitting Member/Non-Torque Torque Transmitting Member.
In order to attach Torque Transmitting Member 19 to a “Cone with One Torque Transmitting Member” of U.S. Pat. No. 8,628,439 that has a Cone that has the cuts and additional features of Cone 26 of this disclosure; a Leading End Reinforcement Plate 25A, a Trailing Sleeve Reinforcement Plate 25B, and a Trailing End Reinforcement Plate 25C are used. A Cone with One Torque Transmitting Member” of U.S. Pat. No. 8,628,439 is referred to as a front pin belt cone assembly 520A in U.S. Pat. No. 8,628,439 (refer to column 90 line 64 to column 99 line 11; and FIGS. 91A, 91B, 92A, 92B, 93 to 101 of U.S. Pat. No. 8,628,439).
Attachment Sleeves 13A-S3 and 13A-S4 are used to attach the Leading End of Torque Transmitting Member 19 to a torque transmitting member carriage 550A of a front pin belt cone assembly 520A of U.S. Pat. No. 8,628,439; using the same method the sleeves of the leading end of a pin belt torque transmitting member 590 are attached to its torque transmitting member carriage 550A in U.S. Pat. No. 8,628,439 (refer to column 90 line 63 to column 91 line 48 of U.S. Pat. No. 8,628,439).
The bottom end of Attachment Sleeve 13B-S3 has a Locking Ring Groove 13B-S4, which is used to secure Attachment Sleeve 13B-S3 to its cone by sliding a fastener such as a Dome Shaped Nut or a Ball Clamp (which is preferred) into Attachment Sleeve 13B-S3, and securing the fastener by inserting a Locking Ring into Locking Ring Groove 13B-S4 (refer to U.S. Pat. No. 8,628,439 for details).
Attachment Sleeve 13B-S3 is used to connect Torque Transmitting Member 19 to its Trailing End Slide; using the same method as the method used to connect the trailing end of a pin belt torque transmitting member 590 to its trailing end slide 565-S1, described in U.S. Pat. No. 8,628,439 (see FIGS. 91A, 91B, 92A, 92B, 93 to 99 of U.S. Pat. No. 8,628,439).
Additionally, Trailing End Reinforcement Plate 13C also has Left Reinforcement Plate 13C-S4 that is shaped to the left of Tooth 13C-S3; and a Right Reinforcement Plat 13C-S5 that is shaped to the right of Tooth 13C-S3. Left Reinforcement Plat 13C-S4 and Right Reinforcement Plat 13C-S5 each have two Holes 13C-S6 for a Reinforcement Wire 20 each. Holes 13C-S6 should be vertically located so that the neutral-axis of Torque Transmitting Member Section 19-M1 vertically coincides with the neutral-axis of its Transmission Belt. And Holes 13C-S6 should align with Holes 13-S5 of Reinforcement Plate 13.
In addition, Trailing End Reinforcement Plate 13C also has a Locking Ring Pin 13C-S7. Locking Ring Pin 13C-S7 is used to secure the Trailing End of Torque Transmitting Member 19 to its Cone by sliding a fastener such as a Dome Shaped Nut or a Ball Clamp (which is preferred) into Locking Ring Pin 13C-S7, and securing the fastener by inserting a Locking Ring into Locking Ring Groove 13C-S8 of Locking Ring Pin 13C-S7.
Torque Transmitting Member 19 should be designed so that “Locking Ring Pin 13C-S7 of Trailing End Reinforcement Plate 13C” and “Attachment Sleeve 13B-S3 of Trailing Sleeve Reinforcement Plate 13B” can slide in the same Trailing End Cut of their cone; in a manner so that Locking Ring Pin 13C-S7 engages with the front-surface of its Trailing End Cut, which is the surface of its Trailing End Cut that prevents Locking Ring Pin 13C-S7 from moving towards the Leading End of Torque Transmitting Member 19. The engagement of Locking Ring Pin 13C-S7 with the front-surface of its Trailing End Cut can be used to transfer Reverse Torque between Torque Transmitting Member 19 and its Cone. Reverse Torque is torque that pulls the Trailing End of Torque Transmitting Member 19 towards the Leading End of Torque Transmitting Member 19. If necessary, some movement/play between Attachment Sleeve 13B-S3 and its Trailing End Cut can be allowed. And if there are interferences between the fastener for Locking Ring Pin 13C-S7 and the fastener for Attachment Sleeve 13B-S3, then it is not necessary to use the fastener for Attachment Sleeve 13B-S3.
It is also preferable (but not necessarily) that Locking Ring Pin 13C-S7 can engage with the rear-surface of its Trailing End Cut, which is the surface of its Trailing End Cut that prevents Locking Ring Pin 13C-S7 from moving away from the Leading End of Torque Transmitting Member 19.
The Trailing End Cuts for a cone are shown and labeled as trailing end cuts 540-S6 in FIG. 112B of U.S. Pat. No. 8,628,439; and shown and labeled as Torque Transmitting Member Trailing End Cut 12-A2 and Non-Torque Transmitting Member Trailing End Cut 12-B2 in
The Leading End Cuts for a cone are shown and labeled as leading end cuts 540-S1 in FIG. 112B of U.S. Pat. No. 8,628,439; and shown and labeled as Torque Transmitting Member Leading End Cut 12-A1 and Non-Torque Transmitting Member Leading End Cut 12-B1 in
If a Cone uses one Torque Transmitting Member 19, then one Leading End Cut of said Cone is used for inserting Attachment Sleeves 13A-S3 and 13A-S4 of Leading End Reinforcement Plate 13A of that Torque Transmitting Member 19. And if a Cone uses two oppositely positioned Torque Transmitting Members 19, then both Leading End Cuts of said Cone are used for inserting Attachment Sleeves 13A-S3 and 13A-S4 of a Leading End Reinforcement Plate 13A of a Torque Transmitting Member 19. Here into each Leading End Cut, Attachment Sleeves 13A-S3 and 13A-S4 of a Leading End Reinforcement Plate 6A of a Torque Transmitting Member 19 are inserted.
Torque Transmitting Member 19 is shown in
Torque Transmitting Member Section 19-M1 comprises of the following previously described Reinforcement Plates for Torque Transmitting Member Section 19-M1: Leading End Reinforcement Plate 13A, Trailing End Reinforcement Plate 13C, and Reinforcement Plates 13, that are joined together by four Reinforcement Wires 20, Longitudinal Elastomer Members 19-M1-S2, and Lateral Elastomer Member 19-M1-S1. Trailing Sleeve Reinforcement Plate 13B will not be used.
Trailing Sleeve Reinforcement Plate 13B, which if used, will perform the same purpose as Trailing Sleeve Reinforcement Plate 6B. Torque Transmitting Member Section 19-M1 does not use Trailing Sleeve Reinforcement Plate 13B because here in order to control and maintain and the axial alignment of the rear-end of Torque Transmitting Member Section 19-M1, the axial alignment of Locking Ring Pin 13C-S3 is controlled and maintained by using a Telescope of the “Telescopes for maintaining the normality and the axial position of two oppositely positioned Locking Ring Pins” section below.
Positioned between all Reinforcement Plates of Torque Transmitting Member Section 19-M1 are two Longitudinal Elastomer Members 19-M1-S2, one Longitudinal Elastomer Member 19-M1-S2 encases the Reinforcement Wires 20 that are positioned to the left of the teeth of its Reinforcement Plates and the other Longitudinal Elastomer Members 19-M1-S2 encases the Reinforcement Wires 20 that are positioned to the right of the teeth of its Reinforcement Plates (see
Also positioned between all Reinforcement Plates of Torque Transmitting Member Section 19-M1 is a Lateral Elastomer Member 19-M1-S1 (see
The cross-section of Torque Transmitting Member Section 19-M1 except for its Trailing End, has a Left Section, a Right Section, and a Top Section, such that an Empty Middle Section 19-M1-S3 is formed (see
The cross-section of the rear-end (also referred to as the Trailing End) of Torque Transmitting Member Section 19-M1 is identical to the Main Cross-Section of Torque Transmitting Member Section 19-M1 described in the previous paragraph; except that it does not have an Empty Middle Section 19-M1-S3, so that said Left Section, said Right Section and Empty Middle Section 19-M1-S3 are replaced by a solid surface. This is because the cross-section of the rear-end of Torque Transmitting Member Section 19-M1 needs a surface to which Leveling Extension 19-M2 can be attached to.
The rear-end (also referred to as the Trailing End) of Torque Transmitting Member Section 19-M1 is shown in
The front-end of Leveling Extension 19-M2 is fixed/bonded to Trailing End Reinforcement Plate 13C (see
When Torque Transmitting Member 19 is used as the Torque Transmitting Member of a Cone with One Torque Transmitting Member or a Cone with Two Opposite Torque Transmitting Members, an oppositely positioned Torque Transmitting Member/Non-Torque Transmitting Member is attached oppositely of Torque Transmitting Member 19 on its Cone. Empty Middle Section 19-M1-S3 of Torque Transmitting Member 19 is used for inserting a Leveling Extension of said oppositely positioned Torque Transmitting Member/Non-Torque Transmitting Member; in a manner such that said Leveling Extension of said oppositely positioned Torque Transmitting Member/Non-Torque Transmitting Member can enter and exit Torque Transmitting Member 19 as required during Transmission Diameter Change of its Cone.
When assembled on its Cone, Leveling Extension 19-M2 is inserted into the Empty Middle Section of said oppositely positioned Torque Transmitting Member/Non-Torque Transmitting Member in a manner such that it can enter and exit said oppositely positioned Torque Transmitting Member/Non-Torque Transmitting Member as required during Transmission Diameter Change of its Cone.
Depending on whether Torque Transmitting Member 19 is used as a Torque Transmitting Member of a Cone with One Torque Transmitting Member or a Cone with Two Opposite Torque Transmitting Members, said oppositely positioned Torque Transmitting Member/Non-Torque Transmitting Member is either another Torque Transmitting Member 19 or a Non-Torque Transmitting Member 23, which is described below.
In order to help maintain the proper alignment/normality of a Reinforcement Plate; a Reinforcement Plate can have an Alignment Pin 21 (see
Non-Torque Transmitting Member that has a Bottom Surface for Teeth (Base) (
The Non-Torque Transmitting Member described in this section, which is labeled as Non-Torque Transmitting Member 23, is to be used with Torque Transmitting Member 19 described in the previous section. In order to prevent excessive vibration due to centrifugal forces, it preferably has the same weight as its Torque Transmitting Member.
Non-Torque Transmitting Member 23 is similar to Non-Torque Transmitting Member 10, described previously, except that it has a surface on which the bottom surfaces of the teeth of its Transmission Belt can rest.
Non-Torque Transmitting Member 23 is shown in
Non-Torque Transmitting Member Section 23-M1 has a surface on which the bottom surfaces of the teeth of its Transmission Belt can rest. The cross-section of Non-Torque Transmitting Member Section 23-M1, except for its Trailing End has a Left Section, a Right Section, and a Top Section, such that an Empty Middle Section is formed. The cross-section of the Trailing End of Non-Torque Transmitting Member Section 23-M1 is solid, so that it does not have an Empty Middle Section; this is because the cross-section of the Trailing End of Non-Torque Transmitting Member Section 23-M1 needs a surface to which Leveling Extension 23-M2 can be attached; as described previously, Leveling Extension 23-M2 is attached to the Trailing End of Non-Torque Transmitting Member Section 23-M1.
Said Top Section is shaped such that it has a surface on which the bottom surfaces of the teeth of its Transmission Belt can rest. And said Empty Middle Section is used for inserting a Leveling Extension of its Torque Transmitting Member (which is oppositely positioned relative to Non-Torque Transmitting Member 23 on the conical surface of their cone); in a manner such the Leveling Extension of its Torque Transmitting Member is laterally positioned between said Left Section and said Right Section, and vertically positioned between the “surface (which is the conical surface) of the cone to which it is attached” and the bottom surface of said Top Section.
Non-Torque Transmitting Member Section 23-M1 comprises of reinforcement plates that are held together by reinforcement wires and elastomer members.
A Reinforcement Plate for Non-Torque Transmitting Member 23 is shown in
Reinforcement Plate 22 is basically identical to Reinforcement Plates 9-M1 and 9-M2 of Non-Torque Transmitting Member 10, except that it has a Base, which joins the two Reinforcement Plate Pairs (comprising of Reinforcement Plates 9-M1 and 9-M2) into one Reinforcement Plate.
Reinforcement Plate 22 is shown in
Shaped on top of Base 22-S3 are Belt Flange Rests 22-S5. Like Tooth Ends 13-S6, Belt Flange Rests 22-S5 can be used to provide resting bases for the flanges of a Transmission Belt that has flanges, such as Transmission Belt 5. If used with a Transmission Belt that does not have flanges, then Belt Flange Rests 22-S5 are not needed.
The empty space between Left Leg 22-S1 and Right Leg 22-S2 (which is located below Base 22-S3) forms the Empty Middle Section of Non-Torque Transmitting Member 23; it is used for the insertion of the Leveling Extension of Torque Transmitting Member 19.
In order to attach Non-Torque Transmitting Member 23 to a “Cone with One Torque Transmitting Member” of U.S. Pat. No. 8,628,439 that has a Cone that has the cuts and additional features of Cone 26 of this disclosure; a Leading End Reinforcement Plate 22A, a Trailing Sleeve Reinforcement Plate 22B, and a Trailing End Reinforcement Plate 22C are used. A Cone with One Torque Transmitting Member” of U.S. Pat. No. 8,628,439 is referred to as a front pin belt cone assembly 520A in U.S. Pat. No. 8,628,439 (refer to column 90 line 64 to column 99 line 11; and FIGS. 91A, 91B, 92A, 92B, 93 to 101 of U.S. Pat. No. 8,628,439).
Attachment Sleeves 22A-S3 and 22A-S4 are used to attach the Leading End of Non-Torque Transmitting Member 23 to a torque transmitting member carriage 550A of a front pin belt cone assembly 520A of U.S. Pat. No. 8,628,439; using the same method the sleeves of the leading end of a pin belt torque transmitting member 590 are attached to its torque transmitting member carriage 550A in U.S. Pat. No. 8,628,439 (refer to column 90 line 63 to column 91 line 48 of U.S. Pat. No. 8,628,439).
The bottom end of Attachment Sleeve 22B-S3 has a Locking Ring Groove 22B-S4, which is used to secure Attachment Sleeve 22B-S3 to its cone by sliding a fastener such as a Dome Shaped Nut or a Ball Clamp (which is preferred) into Attachment Sleeve 22B-S3, and securing the fastener by inserting a Locking Ring into Locking Ring Groove 22B-S4 (refer to U.S. Pat. No. 8,628,439 for details).
Attachment Sleeve 22B-S3 is used to connect Non-Torque Transmitting Member 23 to its Trailing End Slide; using the same method as the method used to connect the trailing end of a pin belt torque transmitting member 590 to its trailing end slide 565-S1, described in U.S. Pat. No. 8,628,439 (see FIGS. 91A, 91B, 92A, 92B, 93 to 99 of U.S. Pat. No. 8,628,439).
Additionally, Trailing End Reinforcement Plate 22C also has Left Reinforcement Plate 22C-S4 and a Right Reinforcement Plat 22C-S5. Left Reinforcement Plat 22C-S4 and Right Reinforcement Plat 22C-S5 each have two Holes 22C-S6; each Hole 22C-S6 is for a Reinforcement Wire 24. Holes 22C-S6 should be vertically located so that the neutral-axis of Non-Torque Transmitting Member Section 23-M1 vertically coincides with the neutral-axis of its Transmission Belt. And Holes 22C-S6 should align with Holes 22-S4 of Reinforcement Plate 22.
In addition, Trailing End Reinforcement Plate 22C also has a Locking Ring Pin 22C-S7. Locking Ring Pin 22C-S7 is used to secure the Trailing End of Non-Torque Transmitting Member 23 to its Cone by sliding a fastener such as a Dome Shaped Nut or a Ball Clamp (which is preferred) into Locking Ring Pin 22C-S7, and securing the fastener by inserting a Locking Ring into Locking Ring Groove 22C-S8 of Locking Ring Pin 22C-S7.
Non-Torque Transmitting Member 23 should be designed so that “Locking Ring Pin 22C-S7 of Trailing End Reinforcement Plate 22C” and “Attachment Sleeve 22B-S3 of Trailing Sleeve Reinforcement Plate 22B” can slide in the same Trailing End Cut of their cone; in a manner so that Locking Ring Pin 22C-S7 engages with the front-surface of its Trailing End Cut, which is the surface of its Trailing End Cut that prevents Locking Ring Pin 22C-S7 from moving towards the Leading End of Non-Torque Transmitting Member 23. The engagement of Locking Ring Pin 22C-S7 with the front-surface of its Trailing End Cut can be used to transfer Reverse Torque between Non-Torque Transmitting Member 23 and its Cone. Reverse Torque is torque that pulls the Trailing End of Non-Torque Transmitting Member 23 towards the Leading End of Non-Torque Transmitting Member 23. If necessary, some movement/play between Attachment Sleeve 22B-S3 and its Trailing End Cut can be allowed. And if there are interferences between the fastener for Locking Ring Pin 22C-S7 and the fastener for Attachment Sleeve 22B-S3, then it is not necessary to use the fastener for Attachment Sleeve 22B-S3.
It is also preferable (but not necessarily) that Locking Ring Pin 22C-S7 can engage with the rear-surface of its Trailing End Cut, which is the surface of its Trailing End Cut that prevents Locking Ring Pin 22C-S7 from moving away from the Leading End of Non-Torque Transmitting Member 23.
The Trailing End Cuts for a cone are shown and labeled as trailing end cuts 540-S6 in FIG. 112B of U.S. Pat. No. 8,628,439; and shown and labeled as Torque Transmitting Member Trailing End Cut 12-A2 and Non-Torque Transmitting Member Trailing End Cut 12-B2 in

Non-Torque Transmitting Member Leading End Cut 12-B1 is used for inserting Attachment Sleeves 22A-S3 and 22A-S4 of Leading End Reinforcement Plate 22A of Non-Torque Transmitting Member 23.
Non-Torque Transmitting Member 23 is shown in
Non-Torque Transmitting Member Section 23-M1 comprises of the following previously described Reinforcement Plates for Non-Torque Transmitting Member Section 23-M1: Leading End Reinforcement Plate 22A, Trailing End Reinforcement Plate 22C, and Reinforcement Plates 22, that are joined together by four Reinforcement Wires 24, Longitudinal Elastomer Members 23-M1-S2, and Lateral Elastomer Member 23-M1-S1. Trailing Sleeve Reinforcement Plate 22B will not be used.
Non-Torque Transmitting Member Section 23-M1 does not use Trailing Sleeve Reinforcement Plate 22B, because here in order to control and maintain and the axial alignment of the rear-end of Non-Torque Transmitting Member Section 23-M1, the axial alignment of Locking Ring Pin 22C-S3 is controlled and maintained by using a Telescope of the “Telescopes for maintaining the normality and the axial position of two oppositely positioned Locking Ring Pins” section below.
Positioned between all Reinforcement Plates of Non-Torque Transmitting Member Section 23-M1 are two Longitudinal Elastomer Members 23-M1-S2, one Longitudinal Elastomer Member 23-M1-S2 encases the Reinforcement Wires 24 that are positioned to the left of the tooth bases of its Reinforcement Plates; and the other Longitudinal Elastomer Member 23-M1-S2 encases the Reinforcement Wires 24 that are positioned to the right of the tooth bases of its Reinforcement Plates (see
On top of the Bases of the Reinforcement Plates of Non-Torque Transmitting Member 23, a Resting Surface 23-M1-S1, which is made out an elastomer (flexible material), is fixed (see
The cross-section of Non-Torque Transmitting Member Section 23-M1 except for its Trailing End, has a Left Section, a Right Section, and a Top Section, such that an Empty Middle Section 23-M1-S3 is formed (see
The cross-section of the rear-end (also referred to as the Trailing End) of Non-Torque Transmitting Member Section 23-M1 is identical to the Main Cross-Section of Non-Torque Transmitting Member Section 23-M1 described in the previous paragraph; except that it does not have an Empty Middle Section 23-M1-S3, so that said Left Section, said Right Section and Empty Middle Section 23-M1-S3 are replaced by a solid surface. This is because the cross-section of the rear-end of Non-Torque Transmitting Member Section 23-M1 needs a surface to which Leveling Extension 23-M2 can be attached to.
The rear-end (also referred to as the Trailing End) of Non-Torque Transmitting Member Section 23-M1 is shown in
The front-end of Leveling Extension 23-M2 is fixed/bonded to Trailing End Reinforcement Plate 22C (see
When the Cone Assembly of Non-Torque Transmitting Member 23 is fully assembled, Torque Transmitting Member 19 is attached oppositely of Non-Torque Transmitting Member 23 on their Cone. Empty Middle Section 23-M1-S3 of Non-Torque Transmitting Member 23 is used for inserting the Leveling Extension of Torque Transmitting Member 19; in a manner such that the Leveling Extension of Torque Transmitting Member 19 can enter and exit Non-Torque Transmitting Member 23 as required during Transmission Diameter Change of their Cone.
When the Cone Assembly of Non-Torque Transmitting Member 23 is fully assembled, Leveling Extension 23-M2 is inserted into the Empty Middle Section of Torque Transmitting Member 19 in a manner such that it can enter and exit Torque Transmitting Member 19 as required during Transmission Diameter Change of its Cone.

Described in this section are Elastomer Inserts that can be used to replace the Longitudinal Elastomer Members 19-M1-S2 of Torque Transmitting Member 19, and the Longitudinal Elastomer Members 23-M1-S2 of Non-Torque Transmitting Member 23.
An Elastomer Insert 25 is shown in
Elastomer Inserts 25A are preferred over Elastomer Inserts 25, since it is easier to remove undesirable space (looseness) between the Elastomer Inserts and their Reinforcement Plates using Elastomer Inserts 25A. In addition, by using Elastomer Inserts 25A, the Elastomer Inserts can be placed under pre-compression, so that they can resist some tension applied to their Torque Transmitting Member.
Also for Torque Transmitting Member 19 and Non-Torque Transmitting Member 23, it is preferable that the Reinforcement Wires are bonded to their Reinforcement Plates (such as by soldering, clamping, etc.), so that the force on the Reinforcement Plates are transferred directly to their Reinforcement Wires. And it is also preferable that the Elastomer Members used with Torque Transmitting Member 19 and Non-Torque Transmitting Member 23 are bonded to their Reinforcement Plates; this will allow them to resist shear and tensile forces.
Cone with Leveling Extension Raising Sheets (
In order to be able to use a Torque Transmitting Member 19 and a Non-Torque Transmitting Member 23, which use Reinforcement Plates that have a Base; a Cone 26 on which two oppositely positioned Leveling Extension Raising Sheets 27 are attached to its conical surface can be used.
When Torque Transmitting Member 19 and a Non-Torque Transmitting Member 23 are assembled on Cone 26, then one Leveling Extension Raising Sheet 27 is wrapping around Cone 26 in a manner such that it is resting on top of the Leveling Extension of Torque Transmitting Member 19, for all Transmission Diameters of Cone 26. So that the thickness of this Leveling Extension Raising Sheet 27 can compensate for the height of the Bases of the Reinforcement Plates of Torque Transmitting Member 19. In a manner such that the height of the Bases of the Reinforcement Plates of Torque Transmitting Member 19, and the height of the surface of the Leveling Extension Raising Sheet 27 that is resting on top of the Leveling Extension of Torque Transmitting Member 19, is equal or almost equal.
And when Torque Transmitting Member 19 and a Non-Torque Transmitting Member 23 are assembled on Cone 26, then the other Leveling Extension Raising Sheet 27 is wrapping around Cone 26 in a manner such that it is resting on top of the Leveling Extension of Non-Torque Transmitting Member 23, for all Transmission Diameters of Cone 26. So that the thickness of this Leveling Extension Raising Sheet 27 can compensate for the height of the Bases of the Reinforcement Plates of Non-Torque Transmitting Member 23. In a manner such that the height of the Bases of the Reinforcement Plates of Non-Torque Transmitting Member 23, and the height of the surface of the Leveling Extension Raising Sheet 27 that is resting on top of the Leveling Extension of Non-Torque Transmitting Member 23, is equal or almost equal. This will provide level or almost level resting surfaces for the teeth of the Transmission Belt used with Torque Transmitting Member 19 and a Non-Torque Transmitting Member 23.
Leveling Extension Raising Sheets 27 should be able to flex so that they can rests level on top of their Leveling Extension. And for all Transmission Diameters of their Cone 26, Leveling Extension Raising Sheets 27 should never cover their respective Torque Transmitting Member 19 or Non-Torque Transmitting Member 23; so that Leveling Extension Raising Sheets 27 will never interfere with Torque Transmitting Member 19 and Non-Torque Transmitting Member 23.
In order to attach Leveling Extension Raising Sheets 27 to Cone 26, Cone 26 has a Sheet Attachment Disk 28, and a Sheet Attachment Disk 29 fixed to it. To Sheet Attachment Disk 28, the right-ends of the Leveling Extension Raising Sheets 27 are attached by gluing, clamping, etc.; and to Sheet Attachment Disk 29, the left-ends of the Leveling Extension Raising Sheets 27 are attached by gluing, clamping, etc.
Cone with Leveling Extension Raising Surfaces (
In order to be able to use a Torque Transmitting Member and a Non-Torque Transmitting Member, which use Reinforcement Plates that have a Base; a Cone 30 on which two oppositely positioned Leveling Extension Raising Surfaces are shaped can be used. Cone 30, which is described in this section, can be used with Torque Transmitting Member(s) 31 and Non-Torque Transmitting Member 34 described in the section below.
Cone 30 is shown in
The height of Leveling Extension Raising Surfaces 30-S2 should be selected so that the “resting surfaces for the Transmission Belt Teeth” of its Torque Transmitting Member Section 31-M1 and its Non-Torque Transmitting Member Section 34-M1 (see section below), matches or almost matches “the height of the top-surface of Leveling Extensions 31-M2 and 34-M2, which are resting on Leveling Extension Raising Surfaces 30-S2”.
Each Leveling Extension Raising Surface 30-S2 has a Leveling Extension Ramp Clearance 30-S1 and a Member Width Clearance 30-S3.
Each Leveling Extension Ramp Clearance 30-S1 is located between the location where its Leveling Extension enters—and exits its Torque Transmitting Member 31 or its Non-Torque Transmitting Member 34 and the adjacent edge of its Leveling Extension Raising Surface 30-S2. Leveling Extension Ramp Clearance 30-S1 is for a Leveling Extension Ramp 32 described in the section below.
A Member Width Clearance 30-S3 is located between the Trailing End of Torque Transmitting Member 31 and the edge of the Leveling Extension Raising Surface 30-S2 located at to the rear of the Trailing End of Torque Transmitting Member 31; and between the Trailing End of Non-Torque Transmitting Member 34 and the edge of the Leveling Extension Raising Surface 30-S2 located at to the rear of the Trailing End of Non-Torque Transmitting Member 34.
The purpose of Member Width Clearance 30-S3 is to ensure that the width of Torque Transmitting Member 31 and Non-Torque Transmitting Member 34 will not cause the Trailing Ends of Torque Transmitting Member 31 and Non-Torque Transmitting Member 34 to interfere with the Leveling Extension Raising Surfaces 30-S2 located to the rear of them.
Torque Transmitting Member and Non-Torque Transmitting Member for Cone with Leveling Extension Raising Surfaces (
Described in this section is a Torque Transmitting Member 31 and Non-Torque Transmitting Member 34 that can be used with a Cone 30 described in the previous section.
Torque Transmitting Member 31 is shown in
Torque Transmitting Member 31 is identical to Torque Transmitting Member 19 described previously, except for the following features: a) a Leveling Extension Ramp 32 is fixed to its Leading Reinforcement Plate 13A (which is the Reinforcement Plate through which a Leveling Extension enters and exits Torque Transmitting Member 31); b) its Leveling Extension (which here is labeled as Leveling Extension 31-M2) is attached so that its top-surface is level with the “resting surfaces for the Transmission Belt Teeth of its Torque Transmitting Member Section (which here is labeled as Torque Transmitting Member Section 31-M1)”; c) its Leveling Extension has Reinforcement Wires 33; and d) its Leveling Extension has a Member Width Clearance Support 31-M2-S1.
Regarding item a), Leveling Extension Ramp 32 (which is shown in detail in
Leveling Extension Ramp 32 should be able to bend/flex as required (workable but not necessary perfect) as the diameter of the conical surface where it is positioned is changed. In
Regarding item c), its Leveling Extension has Reinforcement Wires 33. This can be omitted if the strength of Reinforcement Wires 33 are not necessary.
Regarding item d), Member Width Clearance Support 31-M2-S1 (which is shown in
Member Width Clearance Support 31-M2-S1 is useful because of the required Member Width Clearances 30-S3 of Cone 30. Without a Member Width Clearance 30-S3, the rear-end of Torque Transmitting Member Section 31-M1 will interfere with the Leveling Extension Raising Surface 30-S2 that positioned to the rear of Member Width Clearance Support 31-M2-S1.
Non-Torque Transmitting Member 34 is shown in
Non-Torque Transmitting Member 34 is identical to Non-Torque Transmitting Member 23 described previously, except for the following features: a) a Leveling Extension Ramp 32 is fixed to its Leading Reinforcement Plate 22A (which is the Reinforcement Plate through which a Leveling Extension enters and exits Non-Torque Transmitting Member 23); b) its Leveling Extension (which here is labeled as Leveling Extension 34-M2) is attached so that its top-surface is level with the “resting surfaces for the Transmission Belt Teeth of its Non-Torque Transmitting Member Section (which here is labeled as Non-Torque Transmitting Member Section 34-M1)”; c) its Leveling Extension has Reinforcement Wires 35; and d) its Leveling Extension has a Member Width Clearance Support 34-M2-S1.
The purposes of modifications a) to d) of the previous paragraph are identical to the purposes of modifications a) to d) for Torque Transmitting Member 31; as such details regarding modifications a) to d) provided previously for Torque Transmitting Member 31, are also applicable for Non-Torque Transmitting Member 34.
A method to control and maintain the axial position of the Trailing Ends of Torque Transmitting Member 19 and Non-Torque Transmitting Member 23 relative to their Cone; is by connecting the Locking Ring Pins of the Trailing End Reinforcement Plates of Torque Transmitting Member 19 and Non-Torque Transmitting Member 23 to a Spline Sleeve 40 (which axial position relative to the Spline of Torque Transmitting Member 19 and Non-Torque Transmitting Member 23 is fixed), through two oppositely positioned telescopes. These two oppositely positioned telescopes will fix the axial positions of the Trailing End Reinforcement Plates of Torque Transmitting Member 19 and Non-Torque Transmitting Member 23 relative to Spline Sleeve 40.
Each Top Member 36 is inserted into an Intermediate Member 37, which is shown in detail in
Each Intermediate Member 37 is inserted into a Bottom Member 38, which is shown in detail in
Additionally, Bottom Member 38 has Cover 38-S2, which has a hole that is large enough to allow Top Shape 37-S1 of Intermediate Member 37 to slide through it, but small enough to prevent Bottom Shape 37-S2 of Intermediate Member 37 from exiting Bottom Member 38. Cover 38-S2 is fixed to the top of Bottom Member 38 after the Bottom Shape 37-S2 of Intermediate Member 37 has been inserted into Hole 38-S1 of Bottom Member 38. Cover 38-S2 can be fixed to the top of Bottom Member 38 through gluing or other means. Bottom Member 38 also has a Bottom End 38-S3, which has a solid surface.
In order to ensure that Intermediate Member 37 does not move towards and away from Bottom Member 38 during the rotation of its Cone; a Spring 39, which is not absolutely required but preferred, pushes Intermediate Member 37 towards Cover 38-S1 of Bottom Member 38 (see
If more than one Intermediate Member are used, then all additional Intermediate Members can be shaped like Intermediate Member 37, by having a Top Shape, a Bottom Shape, a Hole into which the “Top Member or Intermediate Member above it” can be inserted, and a Bottom End; but here, the Top Shapes of these additional Intermediate Members should have a Cover which has a hole that is large enough to allow the Top Shape of the “Intermediate Member above it” to slide through it, but small enough to prevent the Bottom Shape of the “Intermediate Member above it” from exiting the additional Intermediate Member into which it is inserted.
Cover 37A-S2 can be fixed (through gluing, etc.) to the top of Intermediate Member 37A after the Bottom Shape 37-S2 of Intermediate Member 37 has been inserted into Hole 37A-S3 of Intermediate Member 37A.
All additional Intermediate Members can be shaped identically as Intermediate Member 37A; and the Top Member and the Bottom Member of a Telescope can also have the same shape regardless of how many Intermediate Members are used. But obviously the dimensions of these Members have to be revised so that they can perform their function (such as: allow for insertion of the Member above it, prevent the Member inserted into it from exiting, etc.). Accordingly, Telescope 41 uses a Bottom Member 38A, which has the same shape but revised dimension compared to Bottom Member 38, instead of Bottom Member 38.
The axial position of Spline Sleeve 40 relative to the Spline into which it is inserted (see
The method to control and maintain the axial position of the Trailing Ends of Torque Transmitting Member 19 and Non-Torque Transmitting Member 23 relative to their Cone of this section, can also be used with other Torque Transmitting Member(s) and Non-Torque Transmitting Member(s); such as with Torque Transmitting Member 31 and Non-Torque Transmitting Member 34, for example.
The Telescopes of this section can also be used to maintain the normality of the Locking Ring Pins of the Leveling Extensions. But since the axial position of the “Trailing Ends of the Leveling Extensions” are maintained by the Torque Transmitting Member or Non-Torque Transmitting Member into which they are inserted; Shaft Collars for maintaining the axial position of the Spline Sleeve of the Telescopes for the “Trailing Ends of the Leveling Extensions” are unnecessary.
A “Leading End Torque Transmitting Member Reinforcement Plate 44” is shown in
In order to secure “Leading End Torque Transmitting Member Reinforcement Plate 44” to its Cone 49, Slider Base 45 of “Leading End Torque Transmitting Member Reinforcement Plate 44” is slideably inserted into a Slotted Cut 49-S1 (see
And the engagement between Slider Base 45 and Slotted Cut 49-S1 is used to transfer torque from “Leading End Torque Transmitting Member Reinforcement Plate 44” to Cone 49, or Cone 26A, or any other cones that use Slotted Cuts 49-S1.
And in order to increase the “rotational resistance” to supplement the “bending resistance” of Slider Base 45 to resist the moment due to the torque transmitted by its Transmission Belt, Slider Base 45 extends to the right and to the left of its Reinforcement Plate 13. Because of the taper of its Cone 49, increasing the length of Slider Base 45 will also increase the height difference between the lowest point and highest point of Slider Base 45, which in turn will increase the “rotational resistance” of Slider Base 45. A Reinforcement Tube 47 is used to strengthen the extension of Slider Base 45 to the left of “Reinforcement Plate 13”; and a Reinforcement Tube 46 is used to strengthen the extension of Slider Base 45 to the right of “Reinforcement Plate 13”.
And in order to control and maintain the axial position of “Leading End Torque Transmitting Member Reinforcement Plate 44” relative to its Spline 51 (see
A “Leading End Non-Torque Transmitting Member Reinforcement Plate 48” is shown in
In order to secure “Leading End Non-Torque Transmitting Member Reinforcement Plate 48” to its Cone 49, Slider Base 45 of “Leading End Non-Torque Transmitting Member Reinforcement Plate 48” is slideably inserted into a Slotted Cut 49-S1 (see
And like for “Leading End Torque Transmitting Member Reinforcement Plate 44”; for “Leading End Non-Torque Transmitting Member Reinforcement Plate 48”, a Reinforcement Tube 47 is also used to strengthen the extension of Slider Base 45 to the left of “Reinforcement Plate 22”; and a Reinforcement Tube 46 is also used to strengthen the extension of Slider Base 45 to the right of “Reinforcement Plate 22”.
And like for “Leading End Torque Transmitting Member Reinforcement Plate 44”, in order to control and maintain the axial position of “Leading End Non-Torque Transmitting Member Reinforcement Plate 48” relative to its Spline 51 (see
The axial position of Spline Sleeve 50 relative to the Spline into which it is inserted (which is Spline 51), is fixed through two sandwiching Shaft Collars 43. Each Shaft Collar 43 has a set-screw for axially fixing it to Spline 51 (see
Cone Assembly using Cone with Leveling Extension Raising Sheets (
Cone Assembly 55 uses a Cone 26A, which is identical to Cone 26 (see
Attached to Cone Assembly 55 are a Torque Transmitting Member 52 and a Non-Torque Transmitting Member 53. Torque Transmitting Member 52 is identical to Torque Transmitting Member 19; except that for Torque Transmitting Member 52, Leading End Reinforcement Plate 13A is replaced with “Leading End Torque Transmitting Member Reinforcement Plate 44” (see
And Non-Torque Transmitting Member 53 is identical to Non-Torque Transmitting Member 23; except that for Non-Torque Transmitting Member 53, Leading End Reinforcement Plate 22A is replaced with “Leading End Non-Torque Transmitting Member Reinforcement Plate 48” (see
“Leading End Torque Transmitting Member Reinforcement Plate 44” of Torque Transmitting Member 52, and “Leading End Non-Torque Transmitting Member Reinforcement Plate 48” of Non-Torque Transmitting Member 53 are each inserted into a Slotted Cut 49-S1 of their Cone 26A. And the axial position of “Leading End Torque Transmitting Member Reinforcement Plate 44” of Torque Transmitting Member 52 and “Leading End Non-Torque Transmitting Member Reinforcement Plate 48” of Non-Torque Transmitting Member 53, relative to their Spline, are controlled and maintained by Spline Sleeve 50 and sandwiching Shaft Collars 43 (see
And the axial position of the Trailing End Locking Ring Pins of Torque Transmitting Member 52 and Non-Torque Transmitting Member 53 relative to their Spline, are controlled and maintained by using Telescopes, Slider Sleeves, and sandwiching Shaft Collars as described in the “Telescopes for controlling and maintaining the axial position of the Trailing Ends of a Torque Transmitting Member and a Non-Torque Transmitting Member (
The Transmission Diameter of Cone Assembly 55 is changed by changing the axial position of its Cone 26A relative to its Spline, since this also changes the axial position of Cone 26A relative to its Torque Transmitting Member 52 and Non-Torque Transmitting Member 53.
Cone Assembly using Cone with Leveling Extension Raising Surfaces (
Described in this section is a Cone Assembly 59, which uses a Cone 30A that has Leveling Extension Raising Surfaces, see
Cone Assembly 59 uses a Cone 30A, which is identical to Cone 30 (see
Attached to Cone Assembly 59 are a Torque Transmitting Member 56 and a Non-Torque Transmitting Member 57. Torque Transmitting Member 56 is identical to Torque Transmitting Member 31; except that for Torque Transmitting Member 56, Leading End Reinforcement Plate 13A is replaced with “Leading End Torque Transmitting Member Reinforcement Plate 44” (see
And Non-Torque Transmitting Member 57 is identical to Non-Torque Transmitting Member 34; except that for Non-Torque Transmitting Member 57, Leading End Reinforcement Plate 22A is replaced with “Leading End Non-Torque Transmitting Member Reinforcement Plate 48” (see
“Leading End Torque Transmitting Member Reinforcement Plate 44” of Torque Transmitting Member 56, and “Leading End Non-Torque Transmitting Member Reinforcement Plate 48” of Non-Torque Transmitting Member 57 are each inserted into a Slotted Cut 49-S1 of their Cone 30A. And the axial position of “Leading End Torque Transmitting Member Reinforcement Plate 44” of Torque Transmitting Member 56 and “Leading End Non-Torque Transmitting Member Reinforcement Plate 48” of Non-Torque Transmitting Member 57, relative to their Spline, are controlled and maintained by Spline Sleeve 50 and sandwiching Shaft Collars 43 (see
And the axial position of the Trailing End Locking Ring Pins of Torque Transmitting Member 56 and Non-Torque Transmitting Member 57 relative to their Spline, are controlled and maintained by using Telescopes, Slider Sleeves, and sandwiching Shaft Collars as described in the “Telescopes for controlling and maintaining the axial position of the Trailing Ends of a Torque Transmitting Member and a Non-Torque Transmitting Member (
The Transmission Diameter of Cone Assembly 59 is changed by changing the axial position of its Cone 30A relative to its Spline, since this also changes the axial position of Cone 30A relative to its Torque Transmitting Member 56 and Non-Torque Transmitting Member 57.
Described in this section are Reinforcement Plate 61 and Reinforcement Plate 62 that can be used with a Leveling Extension 63, which has flanges that can provide additional resting support for a Flanged Transmission Belt. Here bending of the flanges of a Flanged Transmission Belt is resisted by the longitudinal-tension in the flanges of said Flanged Transmission Belt, since bending of said flanges will increase the diameter of said flanges relative to the diameter of the other portion of said Flanged Transmission Belt. As such, it is recommended that the flanges of a Flanged Transmission Belt have Reinforcement Wires.
A Leveling Extension 63 that can be used with Reinforcement Plates 61 and Reinforcement Plates 62 is shown in
Leveling Extension Base 64 comprises of Supporting Plates 64-M1 that are joined along the length of Leveling Extension Base 64 by Elastomer Members 64-M2, which are bonded to Supporting Plates 64-M1. Supporting Plates 64-M1 are also joined together by Reinforcement Wires 64-M3, which are also bonded to Supporting Plates 64-M1. This setup is selected so that some sufficient resistance that “maintains the substantial normality of Supporting Plates 64-M1 relative to their Leveling Extension Base 64” is provided when an axial-bending-moment is applied to the Supporting Plates 64-M1.
A Supporting Plate 64-M1 is shown in
Transmission Belt Rest 65 of Leveling Extension 63, which is also shown separately in
And in order to maintain the alignment of Leveling Extension Base 64 relative to Transmission Belt Rest 65, and prevent Transmission Belt Rest 65 from separating from Leveling Extension Base 64, Base 65-S1 of Transmission Belt Rest 65 has Protrusions 65-S3 that are inserted into matching Indentations 64-S1 of Leveling Extension Base 64. Indentations 64-S1 are shaped into both, Supporting Plates 64-M1 and Elastomer Members 64-M2 of Leveling Extension Base 64.
Cone for usage with Leveling Extension Ramp Guide 71 (
Described in this section is a Cone 66 that can be used with a Leveling Extension Ramp Guide 71 described in the next section. Cone 66 is shown in
Cone 66 is identical to Cone 30 described previously, except that each Leveling Extension Ramp Clearance 30-S1 is replaced with a Ramp Surface 66-S3. Like Cone 30, Cone 66 has unraised surfaces, which here are labeled as Base Surfaces 66-S1; and raised surfaces, which here are labeled as Raised Surfaces 66-S2 (these surfaces were labeled as Leveling Extension Raising Surfaces 30-S2 for Cone 30).
The purpose of Ramp Surface 66-S3 is to guide a Leveling Extension 63 from Base Surfaces 66-S1 to Raised Surfaces 66-S2 (see
Described in in this section is a Leveling Extension Ramp Guide 71 that guides a Leveling Extension from a Base Surface 66-S1 of a Cone 66 to a Raised Surface 66-S2 of said Cone 66. Between said Base Surface 66-S1 and said Raised Surface 66-S2, a Ramp Surface 66-S3 is shaped. In
Cone 66 and Leveling Extension Ramp Guide 71 can be used with a Torque Transmitting Member 31 and a Non-Torque Transmitting Member 34, for which each their Leveling Extension Ramp 32 have been removed.
Leveling Extension Ramp Guide 71 comprises of the following parts: a Ramp Leveling Base 67, a Ramp Tooth Resting Filler 68, a Left Flange Filler 69, and a Right Flange Filler 70. All parts of said Leveling Extension Ramp Guide 71 should be made out of a flexible elastomer. Note for clarity, Ramp Tooth Resting Filler 68, Left Flange Filler 69, and Right Flange Filler 70 are not shown in
Leveling Extension Ramp Guide 71 guides a Leveling Extension 63 from a Base Surface 66-S1 to a Ramp Surface 66-S3, and then to a Raised Surface 66-S2. Transmission Belt resting surfaces for a Base Surface 66-S1 are provided by the Torque Transmitting Member/Non-Torque Transmitting Member that is resting on said Base Surface 66-S1; and a Transmission Belt resting surface for a Raised Surface 66-S2 is provided by the top surface of the portion of a Leveling Extension 63 that is resting on said Raised Surface 66-S2.
And in order to provide Transmission Belt resting surfaces for a Ramp Surface 66-S3, a Ramp Tooth Resting Filler 68, a Left Flange Filler 69, and a Right Flange Filler 70 are used. In order to achieve this, the bottom surfaces of Ramp Tooth Resting Filler 68, Left Flange Filler 69, and Right Flange Filler 70 are resting on top of the portion of a Leveling Extension 63 that is resting on said Ramp Surface 66-S3 (see
Ramp Tooth Resting Filler 68 (see
Ramp Tooth Resting Filler 68 (see
The rear-end of Ramp Tooth Resting Filler 68 has some considerable thickness, which affects the bending flexibility of Ramp Tooth Resting Filler 68. It is desirable to use a stiff elastomer for Ramp Tooth Resting Filler 68, in order to minimize the deflection of the surface of Ramp Tooth Resting Filler 68 that is supporting the teeth of its Transmission Belt due to the load applied by the teeth of its Transmission Belt. A thinner Ramp Tooth Resting Filler 68 will allow for the usage of a stiffer elastomer, since a thinner Ramp Tooth Resting Filler 68 has more bending flexibility than a thicker elastomer.
In order to allow for the usage of stiffer elastomer, a Ramp Tooth Resting Filler 68A (see
Ramp Tooth Resting Filler 68C is identical to Ramp Tooth Resting Filler 68B, except that it has a Hook 68C-M1-S1 at the front-end of its Top Ramp Tooth Resting Filler Member 68C-M1. Hook 68C-M1-S1 is inserted into a Groove 63A-S1 of its Leveling Extension 63A (see
Leveling Extension 63A of the previous paragraph is shown in
Left Flange Filler 69 and a Right Flange Filler 70 are bonded/glued to the front end of their Leading End Torque Transmitting Member Reinforcement Plate, see
Left Flange Filler 69 (shown by itself in
In order to provide sufficient lateral and vertical stiffness to Filler Shape 69-S1, a Stiffener Shape 69-S2 is shaped to the left (when viewed from the front) of Filler Shape 69-S1. Stiffener Shape 69-S2 has two Reinforcement Wires 69-M1, which can be omitted if Stiffener Shape 69-S2 can be made sufficiently stiff without said Reinforcement Wires 69-M1.
Right Flange Filler 70 (shown by itself in
Ramp Leveling Base 67 of Leveling Extension Ramp Guide 71 (see
When a Supporting Plate 64-M1 is resting at an angle that is not Normal to the conical surfaces of Cone 66, as required for the Supporting Plates 64-M1 that are positioned on Ramp Surface 66-S3 (see
In order to compensate for the difference in taper between “the bottom surfaces of the Supporting Plates 64-M1 that are resting on Ramp Surface 66-S3” and “the surface of Ramp Surface 66-S3 they are resting on”, Ramp Leveling Base 67 is positioned between the bottom surfaces of these Supporting Plates 64-M1 and the surface of Ramp Surface 66-S3 (see
Ramp Leveling Base 67 is a flexible elastomer layer that is resting on Ramp Surface 66-S3 and provides a level (or almost level) resting surface for all Supporting Plates 64-M1 that are resting on Ramp Surface 66-S3. Additionally, Ramp Leveling Base 67 should preferably also be shaped so as to compensate for changes of curvature of Ramp Surface 66-S3, which is due to changes in the diameter of Cone 66 along the width Ramp Leveling Base 67. The ideal/acceptable shape of Ramp Leveling Base 67 can be easily determined by experimentation and/or mathematics.
The rotational position and rotational alignment of Ramp Leveling Base 67 relative to its Cone 66 are constraint by the ends of Ramp Surface 66-S3 (see vertical dash-dot lines of
A preferable alternate to Leveling Extension Ramp Guide 71, which is labeled as Leveling Extension Ramp Guide 72, is shown in
Guiding Member 73 comprises of a Ramp Leveling Base 67 that is connect by “a Left Strap 74 to a Left Flange Filler 69A”, and by “a Right Strap 75 to Right Flange Filler 70A”; and a Strap Connector 76, which connects Left Strap 74 to Right Strap 75, and to which the front-end of Ramp Leveling Base 67 is fixed.
Left Flange Filler 69A is basically identical to Right Flange Filler 70; and Right Flange Filler 70A is basically identical to Left Flange Filler 69. The reason for the “right-to-left swap” is because in
For Leveling Extension Ramp Guide 72, the front-ends of Left Flange Filler 69A and Right Flange Filler 70A are connected to Strap Connector 76 through either Left Strap 74 or Right Strap 75 respectively. And since Strap Connector 76 is held in place radially by its Leveling Extension 63 (see
In order to account for Strap Connectors 76, Ramp Surfaces 66-S3 of Cone 66 have to be slightly modified. Shown in
Cone 66A is identical to Cone 66; except that between each Ramp Surface 66A-S3 and Raised Surface 66A-S2, an Indentation 66A-S4 is shaped (see
Each Indentation 66A-S4 of a Cone 66A, is for the insertion of a Strap Connector 76 of a Leveling Extension Ramp Guide 72. Each Strap Connector 76 will be loosely inserted into its Indentation 66A-S4, since there has to be some play between Indentations 66A-S4 and their Strap Connectors 76, to account for the changes in curvature of their Cone 66 as the Strap Connectors 76 are moved axially; but preferably Indentations 66A-S4 are as narrow as allowable, in order to minimize losses in supporting surfaces of Cone 66A. The acceptable shape for Indentations 66A-S4 can be easily obtained through simple experimentation.
Ramp Surface 66-S3 (see
Since the length of Ramp Surface 66-S3 (on which the bottom surface of Ramp Tooth Resting Filler 68 is resting) is the same for all conical diameters, the top surface of Ramp Tooth Resting Filler 68 has to “stretch lengthwise” more-and-more as the conical diameter where it is positioned is decreased. Since decreasing the conical diameter where Ramp Surface 66-S3 is positioned, results in more bending of Ramp Surface 66-S3. And more bending of Ramp Surface 66-S3 results in a larger length difference between the bottom surface and the top surface of a Ramp Surface 66-S3. In order to avoid having to stretch the top surface of Ramp Tooth Resting Filler 68 as the conical diameter where it is positioned is decreased, Ramp Tooth Resting Filler 68D can be used.
Ramp Tooth Resting Filler 68D is shown in
Rear Member 68D-M1 has a bottom-surface that is shaped so that it can rest on top of its Leveling Extension 63A, a top-surface that is shaped so that it can provide a resting surfaces for the teeth of its Transmission Belt, a rear-surface for fixing it to its Leading End Torque Transmitting Member Reinforcement Plate (in
Additionally, the front-end of the bottom-surface of Rear Member 68D-M1 has a Hook 68D-M1-S1 (see
And Rear Member 68D-M1 also has a Groove 68D-M1-S2 (see
Front Member 68D-M2 has a bottom-surface that is shaped so that it can rest on top of its Leveling Extension 63A, a top-surface that is shaped so that it can provide a resting surface for the teeth of its Transmission Belt, and a rear-surface that is facing the front-surface of Rear Member 68D-M1 (see
Additionally, the front-end of the bottom-surface of Front Member 68D-M2 has a Hook 68D-M2-S1 (see
And the rear-end of Front Member 68D-M2 has a Tongue 68D-M2-S2 (see
Described in in this section is a Ramp Resting Filler 77 that can be used to replace Ramp Tooth Resting Filler 68, Left Flange Filler 69, and Right Flange Filler 70 of a Leveling Extension Ramp Guide 71 described previously.
Top surfaces of Ramp Resting Filler 77 provide level resting surfaces for its Transmission Belt, while the bottom surfaces of Ramp Resting Filler 77 are resting on top of a Leveling Extension 63A (see
The rear-end of Ramp Resting Filler 77 is bonded/glued to the front end of its Leading End Torque Transmitting Member Reinforcement Plate (in
The longitudinal sliding of the layers of Ramp Resting Filler 77 is used to replace the required stretching of the upper sections of Tooth Resting Filler 68, Left Flange Filler 69, and Right Flange Filler 70; due to the bending at different diameters of Tooth Resting Filler 68, Left Flange Filler 69, and Right Flange Filler 70.
Base 77-M1 is shown in
Tooth Rest 77-M2 is shown in
Tooth Rest 77-M2 also has two parallel Grooves 77-M2-S2 that cut through the entire length of Tooth Rest 77-M2; so as not to limit the forward movements of Hooks 77-M3-S1 of Flange Rest 77-M3, which are inserted into them.
Tooth Rest 77-M2 also has a Shelf 77-M2-S3 (see
Shelf 77-M2-S3 is used to replace the resting surface of Base 77-M3-S2 that is discontinued (see
Tooth Rest 77-M2 also has a Front Hook 77-M2-S4, which is inserted into Groove 63A-S1 of its Leveling Extension 63A (see
Flange Rest 77-M3 is shown in
The rear portion of Flange Rest 77-M3 is shaped so that it has two Flange Supports 77-M3-S3 that are joined by a Base 77-M3-S2 (see
Here the front-end of Ramp Leveling Base 67 is connected by Left Strap 74 to the front-end of the Left Stiffener Shape of Flange Rest 77B-M3 (which here is labeled as Left Stiffener Shape 77B-M3-S1), and is connected by Right Strap 75 to the front-end of the Right Stiffener Shape of Flange Rest 77B-M3 (which here is labeled as Right Stiffener Shape 77B-M3-S2).
And like for Guiding Member 73; for Flange Rest 77B-M3, Strap Connector 76 connects Left Strap 74 to Right Strap 75; and the front-end of Ramp Leveling Base 67 is fixed to Strap Connector 76.
Non-Torque Transmitting Member with Bumps (
Bumps 23A-M1-S3 can be used to minimize engagement inaccuracies due to stretching of its Transmission Belt, and can be used to transmit some torque so as to supplement the torque transmitted by its Torque Transmitting Member.
If Bumps 23A-M1-S3 are used with a regular Transmission Belt than the Transmission Diameter of their Cone has to be changed in “2-teeth steps” in order to ensure that Bumps 23A-M1-S3 are properly positioned so as to hold the teeth of their Transmission Belt in their ideal circumferential-position, as shown in
If it is desired to change the Transmission Diameter of a Cone in only “1-tooth steps”, then a Transmission Belt 78 (shown in
Non-Torque Transmitting Member Section 23A-M1 is preferably only used in a CVT for which the tension in their Transmission Belts are reduced during Transmission Diameter change, such as a CVT 6 of U.S. Pat. No. 9,651,123.
Described in this section is a Ramp Leveling Base 67C that can be used to a replace the Ramp Leveling Base 67 of a Leveling Extension Ramp Guide 71, a Leveling Extension Ramp Guide 72, or any other part that uses a Ramp Leveling Base 67.
This is because: a) the “Leading End Cut of a Torque Transmitting Member” and the “base of its Ramp Surface 66-S3” each are aligned/“almost aligned” with a radial line of their Cone; b) the “Leading End Cut of a Torque Transmitting Member” and the “base of its Ramp Surface 66-S3” are aligned/“almost aligned” with different radial lines of their Cone; and c) the space between two different radial lines increases as the diameter of their Cone is increased.
But ideally, the distance between the “Leading End Cut of a Torque Transmitting Member” and the “base of its Ramp Surface 66-S3” should remain constant as the Transmission Diameter of their Cone is changed, so that a Leveling Extension Ramp Guide (refer to Leveling Extension Ramp Guide 71 or Leveling Extension Ramp Guide 72 described earlier) is always ideally position relative to its Ramp Surface 66-S3 for all Transmission Diameters of its Cone.
Additionally, while the “Leading End Cut of a Torque Transmitting Member” and the “Leading End Cut of a Non-Torque Transmitting Member” should be aligned with a radial line of their Cone; for a Ramp Surface 66-S3, it is recommended that only its top-edge or its bottom-edge is aligned with a radial line of its Cone. This is because the length of a Ramp Surface 66-S3 preferably remains constant as the Transmission Diameter of its Cone is changed, since the length of a Ramp Leveling Base 67 (see
Preferably, the top-edge of a Ramp Surface 66-S3 is aligned with a radial line of its Cone; so that the bottom edge of a Ramp Surface 66-S3 will be slightly angled relative to a radial line of its Cone, since this can be compensated for by a Ramp Leveling Base.
Ideally the bottom edge of a Ramp Surface 66-S3 should also be aligned with a radial line of its Cone, so that the bottom edge of a Ramp Surface 66-S3 can support the entire width of its Leveling Extension 63 (see
In order to compensate for the surface of the Cone of a Ramp Surface 66-S3 that does not provide support for its Leveling Extension 63 (or Leveling Extension 63A) because of the angle between the bottom edge of said Ramp Surfaces 66-S3 with a radial line of said Cone, a Ramp Leveling Base 67C that has Filler Surface 67C-S1 can be used (see
The left-edge of Filler Surface 67C-S1 should be straight so that it is aligned with a radial line of its Cone, while the right-edge of Filler Surface 67C-S1 (shown in hidden-lines) should be shaped so as to minimizes the space between it and the bottom edge of its Ramp Surface 66-S3 without interfering with the bottom edge of its Ramp Surface 66-S3 for all Transmission Diameters of their Cone. The bottom surface and the top surface of Filler Surface 67C-S1 should be shaped so that Ramp Leveling Base 67C can smoothly support its Leveling Extension 63, this should also account for twisting of Ramp Surface 66-S3 due to the fact that the bottom edge of a Ramp Surface 66-S3 will be slightly angled relative to a radial line of its Cone. The ideal shape of Filler Surface 67C-S1 can be obtained through basic math, tracing, experimentation, etc.
Cone 66 shown in
“Cone with Rotatable Raised Surfaces” for Replacing Cone 66 (
Described in this section is a Cone Assembly 84, which is a cone that has rotatable Raised Surfaces 80. Cone Assembly 84 should be used instead of Cone 66 for all previously described items that use Cone 66.
Cone Assembly 84 is basically identical to Cone 12 (see
The purpose of Raised Surfaces 80 is to raise their Leveling Extension 63 from a Base Surface to a Raised Surface, just like the purpose of Raised Surfaces 66-S2 and Ramp Surfaces 66-S3 of Cone 66.
The difference is that while Raised Surfaces 66-S2 and Ramp Surfaces 66-S3 are fixed to their Cone, Raised Surfaces 80 can rotate relative to their Cone.
An assembled Cone Assembly 84 is shown in
Rear Ring 81 is shaped like a ring that has a Conical Inner Surface 81-S1 (see
Front Ring 82 is shaped like a ring that has a Conical Inner Surface 82-S1 (see
Cone 79 is shown by itself in
Additionally, Cone 79 also has a Spline Profile 79-S4 for a Spline to be used with Cone 79. Obviously, each cone of this disclosure should have a “means for coupling said cone to a means for transmitting rotation”. Wherein “means for transmitting rotation” can be a shaft, spline, etc.; and “means for coupling said cone to a means for transmitting rotation” can be a spline profile, keyed shaft hole, torque transmitting shaft collar, etc.
Once Raised Surfaces 80 are positioned on Cone 79, they are secured to Cone 79 by fixing Rear Ring 81 to Rear Flange 79-S1 through gluing, through the use of fasteners, etc.; and by sliding Front Ring 82 onto Front Extension 79-S2, and then securing it to Front Extension 79-S2 through the use of Locking Ring 83.
Each Ramp 80-S1 of each Raised Surface 80 is used to guide a Leveling Extension from “the surface of Cone 79 on which Raised Surfaces 80 are resting” to “its Raised Surface”. Preferably, the top-edge of each Ramp 80-S1 is aligned with a radial line of Cone 79; and ideally Ramp 80-S1 is shaped so as to follow the Ramp outline of its Ramp Leveling Base for each resting diameter of its Ramp Leveling Base. The shape of Ramps 80-S1 do not have to be perfect; although if so, Cone Assembly 84 will not provide a perfectly round resting surface for its Transmission Belt, it will still work. A sprocket does not provide a perfectly round resting surface for its chain either, but it works.
The rotational position of a Raised Surface 80 when that Raised Surface 80 needs to be rotated towards its leading end-cut (for Cone 12 the leading end-cuts are labeled as Torque Transmitting Member Leading End Cut 12-A1 and Non-Torque Transmitting Member Leading End Cut 12-B1) is controlled through the engagement of the Rear Surface 80-S2 of that Raised Surface 80 (see
A Bump 85 should be positioned on the “rear surface of the Member Width Clearance Support” of each Torque Transmitting Member and each Non-Torque Transmitting Member used with Cone Assembly 84. The item “Member Width Clearance Support” was previously described in this disclosure, and a Member Width Clearance Support 31-M2-S1 is shown in
An example of a Torque Transmitting Member that has a Bump 85 is shown in
A Bump 85 should be positioned and dimensioned so that when it is assembled on its Cone Assembly 84, it is the only surface of its Torque Transmitting Member or its Non-Torque Transmitting Member that engages with the Rear Surface 80-S2 of the Raised Surface 80 that is used to support the Leveling Extension of its Torque Transmitting Member or its Non-Torque Transmitting Member. This engagement of Bump 85 with said Rear Surface 80-S2 is used to control the rotational position of said Raised Surface 80.
And the rotational position of a Raised Surface 80 when that Raised Surface 80 needs to be rotated away from its leading end-cut (for Cone 12 the leading end-cuts are labeled as Torque Transmitting Member Leading End Cut 12-A1 and Non-Torque Transmitting Member Leading End Cut 12-B1) is controlled through the engagement of its Ramp 80-S1 with the parts that are fixed to the Leading End Reinforcement Plate that is adjacent to its Ramp 80-S1.
Reinforcement Plates with Centrifugal Force Resisting Pins (
Described in this section are Reinforcement Plates that have Pins for radially connecting said Reinforcement Plates to their Cones; so that the centrifugal forces on said Reinforcement Plates are resisted by said Pins, and not by the elastomers and reinforcement wires of their Torque Transmitting Member/Non-Torque Transmitting Member.
Shown in
In order to ensure that Pins 61B-S1 are always engaged with a surface of their Cone, which can be achieved by inserting them each into an unbroken (uninterrupted) slot; the “slot for the Locking Ring Pin of the Leveling Extension of their Torque Transmitting Member” can be replaced with a slot that does not penetrate the surface of its Cone. This is necessary since said “slot for the Locking Ring Pin of the Leveling Extension of their Torque Transmitting Member” will intersect with the slots for Pins 61B-S1.
Shown in
Reinforcement Plates 61B and Reinforcement Plates 62B are not preferred, but optional. They will reduce the tension in their Torque Transmitting Member or Non-Torque Transmitting Member, but they will increase the cost and complexity of their Cone Assembly. Based on calculations, the tension in a Torque Transmitting Member or a Non-Torque Transmitting Member due to the centrifugal forces of their Reinforcement Plates can be kept at a reasonable level.
And not using Reinforcement Plates 61B and Reinforcement Plates 62B will not cause vibration, since: a) the force in the direction of the centrifugal force of a Reinforcement Plate has to be resisted no matter how it is attached; and b) the net force on Cone is always equal, the centrifugal forces of the Reinforcement Plates that are covered by their Transmission Belt will reduce the compression force on their Cone due to the tension in their Transmission Belt, so that there will be no variation in the force on their Cone due to Reinforcement Plates coming in-and-out of contact with their Transmission Belt.
If Reinforcement Plates 61B and Reinforcement Plates 62B are used, then it is recommended that all Reinforcement Plates of their Torque Transmitting Member are Reinforcement Plates 61B, and all Reinforcement Plates of their Non-Torque Transmitting Member are Reinforcement Plates 62B. Since otherwise there would only be only a small benefit in using them.
Since although using them intermittently will reduce the centrifugal load on a “Torque Transmitting Member/Non-Torque Transmitting Member”, it will reduce the arc length of the section which centrifugal force has to be resisted by the tension forces at the ends of that section. And this will give a shallower angle for the tension forces at the ends of that section, so as to reduce the component of said tension forces that counteract the centrifugal force.
The maximum tension in a “Torque Transmitting Member/Non-Torque Transmitting Member” due to the centrifugal forces of all of its Reinforcement Plates can be obtained from the equation (which is based on a 180° section) that species that: 2 times the Tension has to be equal to the total centrifugal force of all said Reinforcement Plates.
Cone with Trailing End Torque Transfer Walls (
Described in this section is a Cone with Trailing End Torque Transfer Walls. The purpose of the Trailing End Torque Transfer Walls is to transfer the torque from a Trailing End Reinforcement Plate 87 to its Cone.
The Trailing End Torque Transfer Walls will reduce the moment on a Trailing End Reinforcement Plate due to the height difference between “where the Torque Transmitting Force on said Trailing End Reinforcement Plate is applied” and “the location where the reaction force to said Torque Transmitting Force is applied”.
And
The purpose of a Trailing End Rear Wall 86A-S1 and a Trailing End Front Wall 86B-S1 of a Trailing End Cut 86-S2 is to engage with a Pin of its Trailing End Reinforcement Plate. This engagement will be used to transfer torque from said Trailing End Reinforcement Plate to its Cone 86B.
Trailing End Reinforcement Plate 87 serves the same purpose as Trailing End Reinforcement Plate 13C, and can be attached to its Cone 86, 86A, 86B, or 86C in the same manner Trailing End Reinforcement Plate 13C is attached to its Cone. And Trailing End Reinforcement Plate 88 serves the same purpose as Trailing End Reinforcement Plate 22C, and can be attached to its Cone 86, 86A, 86B, or 86C in the same manner Trailing End Reinforcement Plate 22C is attached to its Cone.
The main purpose of Trailing End Rear Walls 86A-S1 and Trailing End Front Walls 86B-S1 is to engage with the Pins (which are Pin 87-S1 and Pin 88-S1) of their Trailing End Reinforcement Plates (which are Trailing End Reinforcement Plate 87 and Trailing End Reinforcement Plate 88), for the purpose of transferring reverse torque. For this purpose, Trailing End Front Walls 86B-S1 provide the most advantages; since they resist the Force applied on the Trailing End Reinforcement Plates, while Trailing End Rear Walls 86A-S1 are mainly only used to resist the moment due to the height difference between “where said Force is applied” and “the top-end of Trailing End Front Walls 86B-S1”.
As such it is preferred that Trailing End Rear Walls 86A-S1 are omitted, since: a) the side surfaces of Trailing End Cuts 86-S2 can also engage with Pins 87-S1 and 88-S1, and this engagement will not increase the moment applied on the Trailing End Reinforcement Plates of said Pins; and b) without a re-design that can introduce disadvantages, Trailing End Rear Walls 86A-S1 will interfere with Raised Surfaces 80 and the Leveling Extensions of their Torque Transmitting Member and Non-Torque Transmitting Member.
Trailing End Front Walls 86C-S3 are aligned relative to the surface of their Cone so that their rear surfaces are parallel to the “Pins with which they engage” for all diameters of their Cone. Since Trailing End Front Walls 86C-S3 slightly wrap around the surface of their Cone, Trailing End Front Walls 86C-S3 slightly twist lengthwise.
The height of Trailing End Front Walls 86C-S3 should be as high as possible without them interfering with the Longitudinal Elastomer Members of their Torque Transmitting Member or Non-Torque Transmitting Member, and without them interfering with the teeth of their Transmission Belt.
Regarding the previous paragraph,
In
And in order to avoid interference between Trailing End Front Wall 86C-S3 with Trailing End Reinforcement Plate 87 because of the curvature of Trailing End Front Wall 86C-S3 (see
Also,
It is recommended that the taper of Cone 86C is small enough such that only the “Reinforcement Plates in front of the Trailing End Reinforcement Plates” interfere with Trailing End Front Walls 86C-S3, in a manner such that they have to be partially supported by Trailing End Front Walls 86C-S3. Since for this design, the height and top-surface of Trailing End Front Walls 86C-S3 can easily be shaped so that they can support the surfaces of the “Reinforcement Plates in front of the Trailing End Reinforcement Plates”.
Cone 86C is preferred over a Cone that does not have Trailing End Front Walls 86C-S3. As such, it is the preferred that a Cone Assembly 84 is modified so that it also has Trailing End Front Walls.
In this section, the preferred Torque Transmitting Member for a “Cone with One Torque Transmitting Member” or a “Cone with Two Oppositely Positioned Torque Transmitting Members” is described. The Torque Transmitting Member of this section is labeled as Torque Transmitting Member 91; and it is designed to be used with “Cone with rotatable raised surfaces” which also has “Trailing End Torque Transfer Walls”, such as a Cone Assembly 84A described earlier.
The Transmission Belt to be used with Torque Transmitting Member 91, which is labeled as Transmission Belt 90, is shown in
The removed material of Teeth 90-S2 of Transmission Belt 90 due to the tapers of its side surfaces will allow additional material for the teeth of the Reinforcement Plates used with Transmission Belt 90, so that the bases of the teeth of said Reinforcement Plates can be made thinner. Additionally, the tapers of the side surfaces of Transmission Belt 90 can help align the Reinforcement Plates used with Transmission Belt 90 during engagement.
Additionally, Belt 90-S1 of Transmission Belt 90 has flanges that can provide additional resting support for Transmission Belt 90. Here bending of the flanges of a Belt 90-S1 is resisted by the longitudinal-tension in the flanges of Belt 90-S1, since bending of said flanges will increase the diameter of said flanges relative to the diameter of the other portion of Belt 90-S1. As such, in order to increase the longitudinal-tension resistance of the flanges of Belt 90-S1, the flanges of Belt 90-S1 each have a Reinforcement Wire 90-M1.
Torque Transmitting Member 97 is shown in
Torque Transmitting Member Section 97-M1 has teeth that can engage with the teeth of its Transmission Belt. The cross-section of Torque Transmitting Member Section 97-M1, except for its Trailing End has a Left Section, a Right Section, and a Top Section, such that an Empty Middle Section is formed. The cross-section of the Trailing End of Torque Transmitting Member Section 19-M1 does not have an Empty Middle Section.
Said Top Section is shaped such that it has teeth that can engage with the teeth of its Transmission Belt, and such that it can support its Transmission Belt when it is resting on it. And said Empty Middle Section is used for inserting a Leveling Extension of an oppositely positioned Torque Transmitting Member (another Leveling Extension 97-M2) or an oppositely positioned Non-Torque Transmitting Member; in a manner such the Leveling Extension of an oppositely positioned Torque Transmitting Member/Non-Torque Transmitting Member is laterally positioned between said Left Section and said Right Section, and vertically positioned between the “surface of the Cone to which it is attached” and the bottom surface of said Top Section.
Torque Transmitting Member Section 97-M1 comprises of reinforcement plates that are held together by reinforcement wires and elastomer members.
The basic reinforcement plate for Torque Transmitting Member Section 97-M1, which is labeled as Reinforcement Plate 91, is shown in
The bottom surfaces of Left Plate 91-S1 and Right Plate 91-S2 have a taper that preferably matches the taper of their cone, so that Tooth 91-S3 is horizontally aligned when Reinforcement Plate 91 is resting on the surface of its cone.
Left Plate 91-S1 and Right Plate 91-S2 are connected by a Tooth 91-S3 through Tooth Ends 90-S4, which are shaped on the left-end and right-end of Tooth 91-S3 (see
Tooth 90-S3 is shaped like a beam that in addition to Tooth Ends 90-S3, has a Tooth Cavity 91-S5 and a Base 91-S6. Base 91-S6 has two Side Channels 91-S7, which are used for the insertion of Leveling Extension Flange Supports 104-S1 of Leveling Extension 97-M2 (see
Additionally, Left Plate 91-S1 and Right Plate 91-S2, each have two Holes 91-S8 for a Reinforcement Wire 98 (see
In order to attach Torque Transmitting Member 97 to a cone for a “Cone with One Torque Transmitting Member” or a “Cone with Two Oppositely Positioned Torque Transmitting Members”, such as a Cone Assembly 84A; a Leading End Reinforcement Plate 91C, a Trailing Sleeve Reinforcement Plate 91D, and a Trailing End Reinforcement Plate 91E are used.
As outlined previously, Leading End Reinforcement Plate 91B comprises of a Tooth 91B-S3 that is supported at its sides by Left Tube 91B-S1 and Right Tube 91B-S2, in a manner so that an empty space is formed between Left Tube 91B-S1 and Right Tube 91B-S2 beneath Tooth 91B-S3 (see
And Tooth 91B-S3 of Leading End Reinforcement Plate 91B is identical to Tooth 91-S3 of Reinforcement Plate 91, except that it has Fillets 91B-S4. A Leveling Extension is inserted into the front-end of Leading End Reinforcement Plate 91B. And as said Leveling Extension is inserted into Leading End Reinforcement Plate 91B, it bends down as it descends from the Raised Surface adjacent to Leading End Reinforcement Plate 91B. Fillets 91B-S4 are shaped so as to remove the surfaces of Tooth 91B-S3 that will interfere with the Flanges of said Leveling Extension as it is inserted Leading End Reinforcement Plate 91B.
Additionally, the bottom surfaces of Left Tube 91B-S1 and Right Tube 91B-S2 are fixed to a Slider 91B-S5. During assembly, Slider 91B-S5 is slide-ably inserted into the Torque Transmitting Member Leading End Cut of its Cone Assembly 84A (the position and shape of a Torque Transmitting Member Leading End Cut is shown in
The slot of Torque Transmitting Member Leading End Cut into which Slider 91B-S5 is inserted has the shape of a Slot 92;
The engagement between Slider 91B-S5 and Slot 92 are used to: a) transfer torque from Leading End Reinforcement Plate 91B to its Cone Assembly 84A; and b) radially fix Leading End Reinforcement Plate 91B to its Cone Assembly 84A. In order to achieve this, the bottom portion of Slider 91B-S5 has two Protrusions 91B-S7 (see
The top-surface of Slider 91B-S5 is labeled as Slider Top Surface 91B-S6 (see
Slider Top Surface 91B-S6 preferably has a diameter that is as large as possible (so that it can provide an almost ideal resting surface even at the “largest diameter Leveling Extension resting surface” of its Cone Assembly 84A; without exceeding the “smallest diameter Leveling Extension resting surface” of its Cone Assembly 84A (so that it will not have surface that rises above the top-surface of its Cone Assembly 84A when it is positioned at the “smallest diameter Leveling Extension resting surface” of its Cone Assembly 84A).
Also, the center of Slider Top Surface 91B-S6, the mid-width of Tooth 91B-S3, and the center of the Cone Assembly 84A used with Leading End Reinforcement Plate 91B should all align with a radial-line of the Cone Assembly 84A used with Leading End Reinforcement Plate 91B (see
Like Hole 44-S1 of “Leading End Torque Transmitting Member Reinforcement Plate 44” (see
A Belt Resting Filler 93 is fixed (bonded/glued/etc.) to the front end of Leading End Reinforcement Plate 91C (see
Belt Resting Filler 93 is shown by itself in
Regarding item a), Attachment Sleeve 91D-S5, like Attachment Sleeve 6B-S1, is used for the insertion of a Trailing End Slide; with which the axial position of the trailing end of its Torque Transmitting Member can be controlled and maintained.
Said Trailing End Slide slides in the Torque Transmitting Member Trailing End Cut of its Cone 84A (the position and shape of a Torque Transmitting Member Trailing End Cut is shown in
Pin 91E-S4 of Trailing End Reinforcement Plate 91E, like said Trailing End Slide, also slides in the Torque Transmitting Member Trailing End Cut of its Cone 84A. Said Torque Transmitting Member Trailing End Cut is shaped based on the required rotational positions of Pin 91E-S4 for each Transmission Diameter. As such, in order to ensure that said Trailing End Slide can properly engage with Attachment Sleeve 91D-S5 for each Transmission Diameter, Attachment Sleeve 91D-S5 is connected to Left Plate 91D-S1 through an Extender 91D-S4, which length can be adjusted as required; and Attachment Sleeve 91D-S5 has a slotted hole that allow for some rotational movements between Attachment Sleeve 91D-S5 and its Trailing End Slide.
Regarding item b), the inclined bottom surface of Trailing Sleeve Reinforcement Plate 91D, which is due to Cut 91D-S2, is shaped so that it can rest on the top surface of its Trailing End Front Wall 84A-S1. For this purpose, the taper of Cone Assembly 84A should be selected so that only the bottom surface of Trailing Sleeve Reinforcement Plate 91D needs to rest on the top surface of its Trailing End Front Wall 84A-S1.
Also, the surfaces of Right Plate 91E-S2 that will interfere with its Trailing End Front Wall 84A-S1 are removed by a Cut 91E-S3.
A Rod 91E-S4 is shaped at the center of the bottom surface of Tooth 91E-S3. Rod 91E-S4 is used for the insertion of Wall Engagement Insert 94. And the bottom-end of Rod 91E-S4 has a Locking Ring Groove 91E-S5.
Additionally, Left Plate 91E-S1 and Right Plate 91E-S2, each have two Holes 91E-S6 for a Reinforcement Wire 98 (see
Wall Engagement Insert 94 is shown in
In order to secure Trailing End Reinforcement Plate 91E to its cone, a Clamping Washer 95 is used (see
Clamping Washer 95 also has a Hole 95-S1. During assembly, first Wall Engagement Insert 94 is inserted into Rod 91E-S4 of Trailing End Reinforcement Plate 91E (see
Clamping Washer 95 has to rotate relative to Rod 91E-S4 as the axial position of Trailing End Reinforcement Plate 91E is changed; as such, it is recommended that friction between Hole 95-S1 and Rod 91E-S4 is minimized. Also, here the bottom surface of Wall Engagement Insert 94 is resting on Top Surface 95-S2 of Clamping Washer 95.
Torque Transmitting Member 97 is shown in
Torque Transmitting Member Section 97-M1 comprises of the following previously described Reinforcement Plates for Torque Transmitting Member Section 97-M1: Leading End Reinforcement Plate 91C, Trailing Sleeve Reinforcement Plate 91D, Trailing End Reinforcement Plate 91E, and Reinforcement Plates 91, that are joined together by four Reinforcement Wires 98, Longitudinal Elastomer Members 99, and a Top Surface Elastomer Member 100 (see
Two Longitudinal Elastomer Members 99 are positioned between all adjacent Reinforcement Plates of Torque Transmitting Member Section 97-M1; one Longitudinal Elastomer Member 99 encases the Reinforcement Wires 98 that are positioned to the left of the teeth of its Reinforcement Plates and the other Longitudinal Elastomer Member 99 encases the Reinforcement Wires 98 that are positioned to the right of the teeth of its Reinforcement Plates (see
And placed on top of the top surface of the Reinforcement Plates of Torque Transmitting Member Section 97-M1 is Top Surface Elastomer Member 100 (see
The cross-section of Torque Transmitting Member Section 97-M1 except for its Trailing End (which starts with Trailing End Reinforcement Plate 91E), has a Left Section, a Right Section, and a Top Section, such that an Empty Middle Section 97-M1-S1 is formed (see
In order to attach Leveling Extension 97-M2 to Torque Transmitting Member Section 97-M1, a Front Leveling Extension Plate 101 is used (see
A cross-section of Leveling Extension 97-M2 is shown in
In order to attach the rear-end of Leveling Extension 97-M2 to its cone, the rear-end of Bottom Leveling Extension Half 105 is fixed to a Rear Leveling Extension Plate 107 (see
Top Leveling Extension Half 104 is not attached to Rear Leveling Extension Plate 107, so that the stretching of Top Leveling Extension Half 104 and the compression of Bottom Leveling Extension Half 105 are not constrained relative to each other. Stretching of Top Leveling Extension Half 104 and compression of Bottom Leveling Extension Half 105 is required due to the bending of Leveling Extension 97-M2.
Additionally, Top Leveling Extension Half 104 is shorter than Bottom Leveling Extension Half 105. This is so, in order to avoid interference between the rear-end of Top Leveling Extension Half 104 and its adjacent Trailing End Front Wall 84A-S1.
Additionally, although not shown; the front-end of Leveling Extension 97-M2 should also have a Member Width Clearance Support, which has the same purpose a Member Width Clearance Support 31A-S1 described earlier; and a Bump 85, which was also described earlier.
When Torque Transmitting Member 97 is used as the Torque Transmitting Member of a Cone with One Torque Transmitting Member or a Cone with Two Opposite Torque Transmitting Members, an oppositely positioned Torque Transmitting Member/Non-Torque Transmitting Member is attached oppositely of Torque Transmitting Member 97 on its Cone. Empty Middle Section 97-M1-S1 of Torque Transmitting Member 97 is used for inserting a Leveling Extension of said oppositely positioned Torque Transmitting Member/Non-Torque Transmitting Member; in a manner such that said Leveling Extension of said oppositely positioned Torque Transmitting Member/Non-Torque Transmitting Member can enter and exit Torque Transmitting Member 97 as required during Transmission Diameter Change of its Cone.
When assembled on its Cone, Leveling Extension 97-M2 is inserted into the Empty Middle Section of said oppositely positioned Torque Transmitting Member/Non-Torque Transmitting Member in a manner such that it can enter and exit said oppositely positioned Torque Transmitting Member/Non-Torque Transmitting Member as required during Transmission Diameter Change of its Cone.
Depending on whether Torque Transmitting Member 97 is used as a Torque Transmitting Member of a Cone with One Torque Transmitting Member or a Cone with Two Opposite Torque Transmitting Members, said oppositely positioned Torque Transmitting Member/Non-Torque Transmitting Member is either another Torque Transmitting Member 97 or a Non-Torque Transmitting Member.
A Belt Resting Filler 93 is fixed (bonded/glued/etc.) to the front end of Leading End Reinforcement Plate 91C. Belt Resting Filler 93 is attached and shaped such that its bottom surfaces are resting on top of the portion of a Leveling Extension 97-M2 that is resting on Ramp 80-S1, while the top surfaces of Belt Resting Filler 93 provide resting surfaces for their Transmission Belt (see
In order to adjust the shape Leveling Surface 109-S1 as its resting diameter is changed. Ramp Leveling Base 109 has a Neutral-Axis Cable 110. Neutral-Axis Cable 110 is positioned so the it coincides with the Neutral-Axis of Bottom Leveling Extension Half 105 of Leveling Extension 97-M2 through-out the entire length of Ramp Leveling Base 109 (see
Neutral-Axis Cable 110 is joined to Leveling Surface 109-S1 through a Side Member 109-S3, which is fixed to Leveling Surface 109-S1 and encloses Neutral-Axis Cable 110.
Additionally, ideally Ramp 80-S1 is shaped so as to follow the Ramp outline of Leveling Surface 109-S1 for each resting diameter of Leveling Surface 109-S1.
Ramp Leveling Base 109A Described in this section is a Ramp Leveling Base 109A, which comprises of a Right Ramp Leveling Base 109A-M1 and a Left Ramp Leveling Base 109A-M2. Right Ramp Leveling Base 109A-M1 provides support for Bottom Leveling Extension Half 105 of Leveling Extension 97-M2, and Left Ramp Leveling Base 109A-M2 provides support for Top Leveling Extension Half 104 of Leveling Extension 97-M2.
Here, Right Ramp Leveling Base 109A-M1 and Left Ramp Leveling Base 109A-M2 are resting on Sheet 111; and are prevented from separating through the engagement of Right Block 113 with the with the right-surface of Right Ramp Leveling Base 109A-M1 and the engagement of Left Block 112 with the with the left-surface of Left Ramp Leveling Base 109A-M2 (see
The configuration for Right Ramp Leveling Base 109A-M1 and Left Ramp Leveling Base 109A-M2 shown in
Right Ramp Leveling Base 109A-M1 is shown by itself in
Left Ramp Leveling Base 109A-M2 is shown by itself in
A Belt Resting Filler 93A is shown in
Because of the thickness of Base 109A-M1-S1 of Right Ramp Leveling Base 109A-M1, Base 109A-M2-S1 of Left Ramp Leveling Base 109A-M2, and Sheet 111; Leading End Reinforcement Plate 91C and Ramp 80-S1 have to be modified accordingly. For the items of this section; Leading End Reinforcement Plate 91C is replaced with Leading End Reinforcement Plate 91F, and Ramp 80-S1 is replaced with Ramp 80A-S1.
The ramp for the ramp profile of Right Ramp Leveling Base 109A-M1 and Left Ramp Leveling Base 109A-M2 will not be perfect; since: a) the location of the neutral-axis of Right Ramp Leveling Base 109A-M1 and Left Ramp Leveling Base 109A-M2 for the same ramp section (at a specific conical diameter) will be different; and b) the location of the neutral-axis of Right Ramp Leveling Base 109A-M1 and Left Ramp Leveling Base 109A-M2 within themselves varies along their width. In order to obtain a better fit, Flexible Ramp 116 can be used.
Flexible Ramp 116 is shown in
Right Flexible Ramp 116-M1 (see
And Left Flexible Ramp 116-M2 (see
In order to increase the flexibility of Right Flexible Ramp 116-M1 and Left Flexible Ramp 116-M2, it is recommended that Right Flexible Ramp 116-M1 and Left Flexible Ramp 116-M2 are pre-bent to the largest diameter that they will be used with. And it is also recommended that Right Flexible Ramp 116-M1 has cuts as shown in
The Raised Surfaces of the Cone Assembly used with Flexible Ramp 116 should not have Ramps.
The preferred embodiment of this disclosure is Cone Assembly 84B.
