This application claims priority to Taiwanese Invention Patent Application No. 110148471, filed on Dec. 23, 2021.
The disclosure relates to a bearing seat device, and more particularly to a bearing seat device for installation of a bearing set.
Referring to
Although the conventional turbine power unit may fulfill expected operational requirements, the disassembly, installation and servicing of the bearings 150, 160 are time consuming.
Therefore, an object of the disclosure is to provide a bearing seat device that can alleviate at least one of the drawbacks of the prior art.
According to the disclosure, the bearing seat device includes a bearing seat, a bearing set, a driven module, and an adjusting member. The bearing seat has a mounting hole, an adjusting slot, and an inserting hole. The adjusting slot is spatially communicated with the mounting hole. The inserting hole is spatially communicated with the adjusting slot. The adjusting slot divides a section of the bearing seat that is adjacent to the inserting hole and the mounting hole into a first side compartment and a second side compartment. The inserting hole extends from the first side compartment to the second side compartment. The bearing set is mounted in the mounting hole. The driven module extends into the mounting hole, is supported by the bearing set, and is rotatable relative to the bearing seat. The adjusting member engages the mounting hole, and is operable to adjust a width of the adjusting slot between the first and the second side compartments and a diameter of the mounting hole.
Other features and advantages of the disclosure will become apparent in the following detailed description of the embodiment(s) with reference to the accompanying drawings. It is noted that various features may not be drawn to scale.
Before the disclosure is described in greater detail, it should be noted that where considered appropriate, reference numerals or terminal portions of reference numerals have been repeated among the figures to indicate corresponding or analogous elements, which may optionally have similar characteristics.
It should be noted herein that for clarity of description, spatially relative terms such as “top,” “bottom,” “upper,” “lower,” “on,” “above,” “over,” “downwardly,” “upwardly” and the like may be used throughout the disclosure while making reference to the features as illustrated in the drawings. The features may be oriented differently (e.g., rotated 90 degrees or at other orientations) and the spatially relative terms used herein may be interpreted accordingly.
Referring to
The bearing seat has a top end portion 11, a bottom end portion 12 that is opposite to the top end portion 11 in a vertical direction (Y), a mounting hole 13 that extends along a central axis (L) perpendicular to the vertical direction (Y), an adjusting slot 14 that is spatially communicated with the mounting hole 13, and that is extending along a direction parallel to the vertical direction (Y), an inserting hole 15 that is spatially communicated with the adjusting slot 14, and an air supply passage 16 that is spatially communicated with the mounting hole 13, and that extends in the vertical direction (Y). The bearing seat 10 further has an inner surrounding surface 131 that is disposed in the bottom end portion 12, that surrounds the central axis (L), and that defines the mounting hole 13. The adjusting slot 14 is not in spatial communication with the top end 11, and the adjusting slot 14 extends radially from the mounting hole 13 with respect to the central axis (L). The adjusting slot 14 divides a section of the bearing seat 10 that is adjacent to the inserting hole 15 and the mounting hole 13 into a first side compartment 17 and a second side compartment 18. The inserting hole 15 extends from the first side compartment 17 to the second side compartment 18. In this embodiment, the inserting hole 15 extends along a transverse axis (L1) which is perpendicular to the central axis (L) and the vertical direction (Y). The inserting hole 15 has a funnel-shaped section 151 disposed in the first side compartment 17, and a threaded section 152 disposed in the second side compartment 18.
The bearing set 20 is mounted in the mounting hole 13, and has a plurality of bearings 21 that are aligned along the central axis (L). In this embodiment, there are three bearings 21.
The driven module 30 extends into the mounting hole 13, is supported by the bearing set 20, and is smoothly rotatable relative to the bearing seat 10. The driven module 30 includes a driven member 31 that extends into and is supported by the bearing set 20, and a turbine 32 that is mounted to the driven member 31, that is positioned at one side of the bearing set 20 along the central axis (L), and that is adapted to be driven rotatably by pressurized air supplied from the air supply passage 16. In this embodiment, the turbine 32 corresponds in position to the air supply passage 16 and is located at a bottom end of the air supply passage 16, and the driven member 31 is a cutting tool.
The adjusting member 40 engages the mounting hole 15, and has a head part 41 that is secured to the funnel-shaped section 151 of the inserting hole 15, and a threaded part 42 that is threaded to the threaded section 152 of the inserting hole 15. The adjusting member 40 is operable to adjust a width of the adjusting slot 14 between the first and second side compartments 17, 18 and a diameter of the mounting hole 13. In this embodiment, the adjusting member 40 adjusts the width of the adjusting slot 14 and the diameter of the mounting hole 13 via a screwing action which adjusts how much the threaded part 42 is threaded to the threaded section 152 of the inserting hole 15. The adjustment member 40 is movable between a loosened position where the width of the adjusting slot 14 is greater and the diameter of the mounting hole 13 is greater, and a tightened position where the width of the adjusting slot 14 is smaller and the diameter of the mounting hole 13 is smaller.
Referring to
When the adjusting member 40 is in the loosened position, the width of the adjusting slot 14 between the first side compartment 17 and the second side compartment 18 is greater than in the tightened position, and the diameter of the mounting holes 13 is also greater so that there is a clearance between the bearings 21 and the inner surrounding surface 131. The clearance between the bearings 21 and the inner surrounding surface 131 allows the bearings 21 and the driven set 30 to be easily detached from the mounting hole 13.
In other words, the bearing set 20 can be easily mounted or removed relative to the mounting hole 13 in the bearing seat device of the present disclosure just by operating the adjusting member 40. Therefore, the bearing set 20 can be easily serviced or replaced which can save time and reduce costs.
In summary of the above, the bearing seat device according to the present disclosure has a simple structure and is easy to operate, thereby achieving the object of the present disclosure.
In the description above, for the purposes of explanation, numerous specific details have been set forth in order to provide a thorough understanding of the embodiment(s). It will be apparent, however, to one skilled in the art, that one or more other embodiments may be practiced without some of these specific details. It should also be appreciated that reference throughout this specification to “one embodiment,” “an embodiment,” an embodiment with an indication of an ordinal number and so forth means that a particular feature, structure, or characteristic may be included in the practice of the disclosure. It should be further appreciated that in the description, various features are sometimes grouped together in a single embodiment, figure, or description thereof for the purpose of streamlining the disclosure and aiding in the understanding of various inventive aspects; such does not mean that every one of these features needs to be practiced with the presence of all the other features.
