Problems solved by technology

[0006] However, increasing the thickness of the cage in the prior art will inevitably lead to an increase in the weight of the cage, which is not conducive to the flexibility of the cage during rotation.
[0007] In addition, increasing the thickness of the cage directly leads to an increase in raw materials, which in turn increases the production cost of the bearing

Abstract

The invention provides a bearing retainer which comprises a retainer body and a retainer hole which penetrates through the retainer body in thickness direction of the retainer body; the side wall of the retainer hole, which contacts the rolling surface of a rolling body, is provided with a flange, and the flange extends along the rolling surface of the rolling body. By the adoption of the structural arrangement, on the basis of ensuring the rotation flexibility of the retainer, the bearing retainer provided by the invention can effectively reduce contact stress between the retainer and the rolling body. The invention also provides a bearing comprising the bearing retainer.

Description

technical field [0001] The invention relates to the field of mechanical parts, in particular to a bearing cage. The invention also relates to a bearing comprising the bearing cage described above. Background technique [0002] With the transformation of our country from a traditional agricultural society to a modern industrialized society, the field of mechanical parts has become relatively mature in various industries. At the same time, it has driven the continuous innovation and progress of bearing application technology. [0003] As a fixed part in machinery, bearings are mainly used to determine the relative position of the rotating shaft and other parts to play a supporting or guiding role. Bearings generally consist of inner rings, outer rings, rolling elements and cages. [0004] The cage of the bearing has the function of keeping the rolling elements at a certain interval in the circumferential direction, preventing the rolling elements from falling off and guiding...
