Invention relates to a lockable slim type universal joint on X and Y rotation axis independent of each.
Invention particularly relates to slim type universal joint used to transmit rotary motion in torque and/or on rotation axis generated by outlet/driving spindle on the system connected thereto into outlet/driving spindle on different axis and allowing independent locking of rotation axis.
Today, universal joints of various shapes according to areas of use (universal joint) are located on two ends of shaft depending on motion transmission system of the vehicle whereon used and are used for providing connection between output shaft and shaft and also transmit the rotary motion on X-Y rotating axis to output shaft located on different axis.
In current application, universal joints lockable axially occupying little space because of slim structure are used. However, X-Y rotating axis of said joints is not lockable independent of each. Not being capable to lock independently causes restriction of rotary motion of each.
Another current application discloses universal joints and shafts providing torque transmission wherein shafts having angular gap between axis are connected. In said application input shaft of universal cap performs universal joint motion in universal housing Pin moving inside circular channel integrated to hole in spherical hole of input spindle and located inside body provides torque transmission. Spherical structure of the universal joint used in said application is similar to present invention. However, it has a slimmer structure and it does not disclose less space occupation.
The application numbered DE102004028013A1 encountered when conducting search on the subject matter discloses a universal joint including hollow bearing bush and supplementary extension parts on joint yoke functioning as locking unit. The application is a universal joint having a first and a second yoke and a journal cross connecting the joint yokes with four bearing journals, each bearing journal being in a hollow cylindrical bearing bush is mounted and wherein each bearing bush by means of a securing device in a yoke is held. The application discloses a system conducting locking by means of interlocking recesses and embossing noses. However, this locking system does not disclose a locking mechanism locking X-Y rotary axis separately and providing motion of their axis independent of each other.
Another document encountered when searching the related field is the application numbered CN206889512U and it discloses a new and three-dimension universal joint. The joint disclosed under the application is produced to eliminate the disadvantages of available two-shaft joints. Said application eliminates mechanical mounting difficulty. The application is similar to present invention of slim type universal joint of lockable axis in respect to slim structure. However, it does not contain an embodiment related to lockable axis.
As a result, due to above described disadvantages and inadequacy of existing solutions, it has been necessary to make development in the related art.
The invention has been developed with inspiration from existing situation and aims to eliminate the above mentioned disadvantages.
Primary purpose of the invention is to transmit the torque generated by driving shaft(n) located on the system and rotary motion on X-Y axis to output shaft located on different axis.
Another purpose of the invention is to provide testing of products such as unmanned air vehicles at desired axis by connecting the vehicle to test systems without preventing free motion of the vehicles and thus prevent effects of results of tests conducted at such axis thereon thanks to independent interlockable of rotary axis.
The structural and characteristics features of the invention and all advantages will be understood better in detailed descriptions with the Figures given below and with reference to the Figures, and therefore, the assessment should be made taking into account the said Figures and detailed explanations.
In this detailed description, the preferred embodiments of the lockable axis slim type universal joint being subject of the invention have been described only for purpose of better understanding of the matter.
Lockable axis slim type universal joint (A) of the invention basically includes three parts, namely, inner part (1), central ring (2) and outer ring (3).
Outer surface of inner part (1) shown in details in
Said spherical inner part (1) on outer surface also includes
Central ring (2) demounted view given in
Pin holes of four on central lower part (2.1) and four on central-upper part (2.2) and facing each other, formed on inner surfaces of said central-lower part (2.1) and central-upper part (2.2) facing each other when central-lower part (2.1) and central-upper part (2.2) are mounted,)
As seen in
In a preferred embodiment of the invention, radial housing-1 (h1) and pin hole-a (a) are in same alignment but have a distance in between, pin hole-b (b) is exactly opposite to pin-a (a), pin hole-c (c) is exactly opposite to pin hole-a (a) and pin hole-b (b), pin hole-d (d) is exactly opposite pin hole-c (c) and formed at 90 degrees angle to each other.
As shown in
As seen in
Outer surface of outer ring (3) is in spherical form and at least one screw hole (k) is formed on upper surface to connect output/driving shaft. Also, alignment diameter (m) is added onto upper surface of outer ring (3). As shown in
Said outré-lower part (3.1) and outer-upper part (3.2) include, formed on inner surfaces facing each other, facing each other when outer-lower part (3.1) and outer-upper part (3.2) are mounted,
As shown in
As shown in
In a preferred embodiment of universal joint (A) disclosed under invention, inner part (1), central ring (2) and outer ring (3) are mounted in a manner
Working principle of universal joint (A) of the invention:
In order to provide locking and rotation of X-Y axis independent of each other;
With universal joint (A) of the invention, torque generated by driving shaft (n) provided in the system and rotary motion on X-Y axis are transmitted to output shaft (o) located on different axis. Said universal joint (A) can also be used for connection to testing system in tests of products such as unmanned air vehicles without preventing free motion and to conduct tests on desired axis thanks to lockable feature of axis during testing.
