Grinding process method of ultra-light narrow bearing sleeve ring

Abstract

The invention relates to a grinding process method of an ultra-light narrow bearing sleeve ring. Compared with the original process, the grinding process method is characterized in that one-time additional annealing is added, one-time grinding circulation is added, a ceramic forming cutter is adopted, and disposable hard turning chamfering is carried out on an assembling chamfer of a bearing part on a turning lathe according to the size requirement of a finished product. According to the grinding process method, the stress in the bearing sleeve ring is effectively released, so that the residual stress is smaller, further the stability of the performance of the sleeve ring is increased, the chamfer size requirement of the finished bearing product is guaranteed, the appearance is bright, the inconsistent size of the assembling chamfers of the finished bearing products is avoided, the collision of a chamfer surface is reduced and the chamfer size of the part of the finished bearing product is not limited by lathe workers for all the processing surfaces.

Description

technical field [0001] The invention relates to a grinding process method, in particular to a grinding process method of an ultra-light and narrow bearing ring. Background technique [0002] The processing of the bearing assembly chamfer and the control of the size of the chamfer are very important for the installation, service life and appearance of the bearing. In the existing ultra-light and narrow bearing ring grinding process, the parts are chamfered and heat-treated, then the surface is roughly ground, the outer diameter, the outer groove, and the outer inner diameter are roughly ground, additional tempering is performed, and the plane is finely ground , outer diameter, outer groove, fine grinding outer diameter, mating surface, polished groove, mating surface, magnetic particle flaw detection, demagnetization, cleaning, final inspection of parts, and finally storage. Due to the characteristics of the ultra-light and narrow bearing itself, the stability of the ferrul...

AI Technical Summary

Problems solved by technology

Due to the characteristics of the ultra-light and narrow bearing itself, the stability of the ferrule itself is not strong, and if there is internal stress, it will cause the ferrule to deform itself

Moreover, the traditional chamfering processing method for bearing assembly is difficult to effectively guarantee the size requirements of the finished bearing parts. The size of the chamfers is different, and the appearance is severely bumped, which directly affects the overall quality requirements of the bearing.
