Problems solved by technology

The cage is used to separate two adjacent rolling elements, so that multiple rolling elements can be evenly distributed between the inner ring and the outer ring along the circumferential direction, so as to avoid collision and friction between two adjacent rolling elements. The frame solves the problem of preventing friction and collision between two adjacent rolling elements, but it does not solve the problem of friction between the rolling element and the cage and the heat dissipation of the heat generated by the friction.

Embodiment 1

[0011] Such as figure 1 , figure 2 , image 3 As shown, the present invention discloses a bearing cage. The technical solution adopted is to include a cage body 1, and the cage body 1 is provided with an upper bias pocket 2 and a lower bias pocket for guiding the rolling elements 5. 3. The number of the upper partial pocket holes 2 and the lower partial pocket holes 3 is even in number and the intervals are evenly arranged.

[0012] The axial centerline 4 of the cage body 1 is at the same distance from both ends of the cage body 1 . The center of the upper eccentric pocket hole 2 is offset upward from the axial centerline 4, and the center of the lower eccentric pocket 3 is offset downward from the axial centerline 4. The offset distance is equal to the installed 2% of the length of the diameter of the rolling element 5.

[0013] Working principle of the present invention: the center of the upper partial pocket hole 2 and the lower partial pocket hole 3 designed by the pr...

Abstract

The invention discloses a bearing retainer. The bearing retainer comprises a retainer body, upward shifting pockets and downward shifting pockets. According to the bearing retainer, the positions of the pockets are shifted, and the centers of rolling bodies can still be in the same plane in the working process of a bearing, that is, the circle centers of the pockets coincide with the sphere centers of the rolling bodies, and the sphere centers of the rolling bodies are kept in the same plane, so that a large 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

technical field [0001] The invention relates to the field of bearings, in particular to a bearing cage. Background technique [0002] Bearings are widely used in automotive and industrial fields. Bearings generally include inner rings, outer rings, cages and rolling elements. The rolling elements are arranged between the inner ring and the outer ring and can rotate to realize the relative rotation between the inner ring and the outer ring. The cage is used to separate two adjacent rolling elements, so that multiple rolling elements can be evenly distributed between the inner ring and the outer ring in the circumferential direction, so as to avoid collision and friction between two adjacent rolling elements. Both frames solve the problem of preventing two adjacent rolling elements from rubbing and colliding, but they do not solve the friction between the rolling elements and the cage and the problem of heat radiation generated by friction. Contents of the invention [00...
