Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, specifically to a bearing ring grinding device for bearing processing. Background Technology

[0002] Bearings are an indispensable basic component in mechanical equipment. Their main function is to support rotating shafts or other moving bodies, guide their rotation or movement, and bear the loads transmitted from the shaft or parts on the shaft. Their core function can be summarized as: reducing frictional resistance during movement and ensuring rotational accuracy.

[0003] After bearings are manufactured, they need to be polished. Currently, polishing the outer ring of a bearing is mostly achieved by clamping the inner ring with jaws and rotating it with the spindle. However, in this mode, the outer ring, which is in a free state, will have its rotational speed forced to change due to frictional resistance after contacting the polishing head, breaking the initial stable following state. This unstable rotational speed causes the relative speed between the outer ring surface and the polishing tool to change continuously, ultimately leading to the core problems of poor polishing accuracy and uneven surface quality. To address this, we provide a bearing ring polishing device for bearing processing. Utility Model Content
