Description
Technical Field
The utility model relates to the field of retainers, in particular to a one-way bearing structure for connecting a stage clutch plate.
Background
The existing bearing for unidirectional power transmission has a complex structure and more parts. The existing one-way transmission bearing structure adopts a bearing retainer, and is matched with a bearing shell to obtain a one-way bearing which has high bearing capacity and can transmit power; however, the spring and the long ball are arranged in the retainer, and the spring is required to support the long ball so as to facilitate unidirectional rotation; in actual use, the spring is easy to slide, so that the stability of the bearing is not good enough; in addition, the number of the long balls in the retainer is singular, so that the number of the locking points initially contacted in the retainer is 3, and the relative locking stability of the retainer is not good enough.
Therefore, improvements to the prior art are yet to be made.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a bearing retainer, and aims to solve the technical problem that the stability of initial contact locking points of a retainer is not stable enough because the number of the initial locking points in the conventional retainer is 3.
In order to achieve the purpose, the technical scheme of the utility model is as follows: a bearing retainer comprises a retainer body, long balls, springs and spring caps, wherein the retainer body is provided with mounting grooves for mounting the long balls and the springs, the number of the mounting grooves is double, and each mounting groove is respectively provided with the long balls; one end of the spring is connected with one side of the mounting groove, the other end of the spring props against the long ball through a spring cap, and the long ball is mounted on the other side of the mounting groove; the number of the long balls is double.
The bearing retainer, wherein, the spring cap sets up the connecting portion of supporting part and cooperation embedding spring, the diameter of supporting part is greater than the diameter of connecting portion.
The bearing retainer, wherein, supporting part and connecting portion structure as an organic whole.
The diameter of the spring is gradually reduced from one end to the other end, and the end with the small diameter is connected with the spring cap.
The bearing retainer is characterized in that the upper panel and the lower panel of the retainer body are provided with lugs, and the lugs are nested in the bearing shell.
The bearing retainer, wherein, the quantity of long ball is 14.
Has the advantages that: the spring of the utility model props the long ball through the spring cap, the spring is not easy to slide relative to the long ball, so that the stability of the bearing is good when the bearing rotates, and because the number of the long ball is double, the number of the initial contact locking points of the retainer, the spline housing and the bearing shell is 4, while the number of the initial contact locking points of the existing retainer is 3, the number of the initial contact locking points of the utility model is one more than that of the existing initial contact locking points, so that the stability of the initial contact locking points is stronger.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples.
As shown in fig. 1-5, the utility model discloses a bearing retainer, which comprises a retainer body 1, long balls 2, springs 3 and a spring cap 4, wherein the retainer body 1 is provided with mounting grooves 10 for mounting the long balls 2 and the springs 3, the number of the mounting grooves 10 is double, and each mounting groove 10 is respectively provided with the long balls 2; one end of the spring 3 is connected with one side of the mounting groove 10, the other end of the spring 3 props against the long ball 2 through the spring cap 4, and the long ball 2 is mounted on the other side of the mounting groove 10; the number of the long balls 2 is double.
After the structure is adopted, the spring cap is arranged between the spring and the long ball, so that the spring cannot easily slide out when the spring abuts against the long ball, the stability of the retaining bracket is improved, the number of the long balls is set to be even, and the number of the mounting grooves is also even, so that the initial locking points of the retainer are 4 according to the design of triangular stress; the number of the long balls in the existing retainer is singular, and according to the triangular stress principle, the number of the initial locking points of the retainer is 3; therefore, the number of the initial locking points of the retainer is one more than that of the conventional retainer, so that the locking stability of the retainer is stronger.
Preferably, the spring cap 4 is provided with a support portion 40 and a connecting portion 41 for fitting and embedding the spring, and the diameter of the support portion 40 is larger than that of the connecting portion 41; therefore, one end of the spring can be inserted through the connecting part, and the supporting part can support the long ball to prevent the spring from sliding outwards.
Preferably, the supporting portion 40 and the connecting portion 41 are of an integral structure, which facilitates processing and manufacturing.
Preferably, the diameter of the spring 3 is gradually reduced from one end to the other end, and the end with the small diameter is connected with the spring cap 4.
Preferably, the upper and lower panels of the frame body 1 are provided with protrusions 11, and are nested in the bearing housing by the protrusions 11.
Preferably, the number of the long balls 2 is 14, so that the number of the initial locking points of the present invention is 4, thereby improving the stability of the locking of the cage.
The spring of the utility model props the long ball through the spring cap, the spring is not easy to slide relative to the long ball, so that the stability of the bearing is good when the bearing rotates, and because the number of the long ball is double, the number of the initial contact locking points of the retainer, the spline housing and the bearing shell is 4, while the number of the initial contact locking points of the existing retainer is 3, the number of the initial contact locking points of the utility model is one more than that of the existing initial contact locking points, so that the stability of the initial contact locking points is stronger.
The above is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, modifications or equivalent substitutions of the technical solution of the present invention without inventive work may be made without departing from the scope of the present invention.
