Technical Field

[0002] Bearing is an important component in modern mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. According to the different friction properties of the moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings. Among them, rolling bearings have been standardized and serialized, but compared with sliding bearings, their radial dimensions, vibrations and noises are larger, and their prices are also higher. The existing patent is a cylindrical grinding processing device for processing the outer ring of a bearing, and the patent publication number is CN217800632U. It includes a table, a movable plate and a fixed column. One end of the upper surface of the table is fixedly connected to the main motor through a mounting frame, and the upper end of the table is fixedly connected to a fixed plate 1, and a groove 1 is provided at the end of the fixed plate 1 away from the main motor.

Therefore, we proposed a precision angular contact ball bearing outer circle grinding device to solve the above-mentioned problems. Utility Model Content
