Abstract

The invention discloses a method for machining a centering roller bearing inner ring with an oil hole on the inside diameter. The machining process route is as follows: roughly grinding end surfaces, roughly grinding inside and outside diameters, roughly grinding the inside diameter, roughly grinding roller tracks, tempering, finely grinding the end surfaces, finely grinding the roller track on one side, finely grinding the inside and the outside diameters, finely grinding the inside diameter, finely grinding the roller track on the other side, and super-grinding the roller tracks. The method can guarantee geometric tolerances of the bearing so that the bearing can meet the national standards.

Description

technical field [0001] The invention relates to a bearing processing method, in particular to a grinding processing method for the inner ring of a self-aligning roller bearing with an oil hole in the inner diameter. Background technique [0002] The inner ring with oil holes is different from other products. The structure of these products is that there are oil holes on the inner diameter and inner and outer diameters, which has a certain impact on the positioning of the grinding process. According to the traditional processing method, the processing cannot meet the standard requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a self-aligning roller bearing inner ring with oil holes in the inner diameter that improves the machining accuracy of the inner ring with oil holes and changes the grinding positioning method to ensure that the bearing finally meets the requirements of the national standard proces...
