Description

Technical Field

[0001] The invention relates to the technical field of bearing processing, and in particular to a vertical grinding processing tool for a wind power bearing and a processing technology thereof. Background Art

[0002] Bearings are an important component in mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Bearings are widely used in the field of wind power. Bearings consist of four parts: outer ring, inner ring, rolling element and cage. During the grinding process of the inner ring of the bearing, in order to ensure the processing quality, it is necessary to use tooling to limit and fix the inner ring of the bearing.

[0003] In the current application of wind turbine bearing vertical grinding tooling, the traditional threaded self-locking method is generally used to clamp and fix the inner ring of the bearing. The tooling itself lacks other limit locking mechanisms, and the clamping part is prone to loosening during the grinding of the inner ring of the bearing, resulting in a small displacement of the inner ring of the bearing, affecting the grinding quality of the inner ring of the bearing.
