Description

Technical Field

[0001] The utility model belongs to the technical field of bearing rings, in particular to a bearing ring for an automobile clutch. Background Art

[0002] Bearing rings are very important in the use of clutch. Bearing rings are annular parts of radial rolling bearings with one or more raceways. They can generally be divided into inner rings and outer rings. The inner ring refers to the bearing ring with its raceway on the outer surface, while the outer ring refers to the bearing ring with its raceway on the inner surface.

[0003] When the bearing ring is working, the internal balls roll between the inner ring and the outer ring. Due to the contact and friction between the balls and the inner ring and the outer ring, the raceways of the inner ring and the outer ring generate a higher temperature. Long-term contact and friction and the bearing ring being at a high temperature for a long time will cause damage to the raceway and shorten the service life of the bearing ring.
