Abstract

The invention discloses a bearing retainer which comprises a retainer body, an upper inclined pocket and a lower inclined pocket. According to the invention, the positions of the pockets are deviated, the centers of the rolling bodies can still be in the same plane in the working process of the bearing, namely the circle centers of the pockets are superposed with the spherical centers of the rolling bodies, and the spherical centers of the rolling bodies are kept in the same plane, so that a larger eccentric gap is formed between the rolling bodies and the retainer in the working process of the bearing, the heat dissipation performance of the bearing is improved, and the performance and the service life of the bearing are prevented from being influenced by overheating of the bearing.

Description

Bearing retainer

Technical Field

The invention relates to the field of bearings, in particular to a bearing retainer.

Background

Bearings are widely used in automotive and industrial applications. A bearing generally includes an inner race, an outer race, a cage, and rolling elements. The rolling body is arranged between the inner ring and the outer ring and can rotate to realize relative rotation between the inner ring and the outer ring. The retainer is used for separating two adjacent rolling elements, makes a plurality of rolling elements can follow the even distribution in circumference between inner circle and outer lane to avoid two adjacent rolling elements to bump and rub, current retainer has all been solved and has not let two adjacent rolling elements take place to rub and collide, but does not have fine solution rolling element and the heat dissipation problem of the heat that produces to the friction between the retainer.

Disclosure of Invention

In view of the problems in the prior art, the invention discloses a bearing retainer which adopts the technical scheme that the bearing retainer comprises a retainer body, wherein an upper partial pocket and a lower partial pocket for guiding a rolling body are arranged on the retainer body, and the upper partial pocket and the lower partial pocket are even in number and are uniformly distributed at intervals.

In a preferred embodiment of the present invention, the holder body has an axial centerline that is spaced from both end surfaces of the holder body by the same distance. The circle center of the upper partial pocket deviates upwards from the axial center line, the circle center of the lower partial pocket deviates downwards from the axial center line, and the deviation distance is 2% of the diameter length of the mounted rolling body.

The invention has the beneficial effects that: the invention provides a bearing retainer, which is characterized in that the positions of pockets are deviated, the centers of rolling bodies can still be in the same plane in the working process of a bearing, namely, the centers of the pockets coincide with the spherical centers of the rolling bodies, and the spherical centers of the rolling bodies are kept in the same plane, so that a larger eccentric gap is formed between the rolling bodies and the retainer in the working process of the bearing, the heat dissipation performance of the bearing is improved, and the performance and the service life of the bearing are prevented from being influenced by overheating of the bearing.

Detailed Description

Example 1

As shown in fig. 1, 2 and 3, the invention discloses a bearing retainer, which adopts the technical scheme that the bearing retainer comprises a retainer body 1, wherein an upper inclined pocket 2 and a lower inclined pocket 3 for guiding a rolling body 5 are arranged on the retainer body 1, and the upper inclined pocket 2 and the lower inclined pocket 3 are even in number and are uniformly arranged at intervals.

The axial center line 4 of the retainer body 1 is at the same distance from both end faces of the retainer body 1. The circle center of the upper partial pocket 2 is deviated upwards from the axial center line 4, the circle center of the lower partial pocket 3 is deviated downwards from the axial center line 4, and the deviation distances are 2% of the diameter length of the mounted rolling body 5.

The working principle of the invention is as follows: the centers of the upper partial pocket 2 and the lower partial pocket 3 designed by the invention are deviated from the axial center line 4, and after the rolling bodies 5 are installed, the centers of the rolling bodies 5 in all the pockets are on the axial center line 4, so that a larger gap is formed between each rolling body 5 and the retainer body 1, and the heat dissipation effect of the bearing is improved.

Components not described in detail herein are prior art.

Although the present invention has been described in detail with reference to the specific embodiments, the present invention is not limited to the above embodiments, and various changes and modifications without inventive changes may be made within the knowledge of those skilled in the art without departing from the spirit of the present invention.
