Bearing inner and outer ring grinding device

Abstract

The invention discloses a bearing inner and outer ring grinding device. The device comprises a supporting platform and supporting legs, the supporting legs are welded to the bottom of the supporting platform, a first groove is formed in a round plate, the inner wall of one side of the first groove is embedded with a first bearing, the inner part of the first bearing is in interference connection with a first threaded rod, a rectangular supporting plate is welded to the top surface of a T-shaped sliding block, a third bearing is inlaid at one end of the top surface of the rectangular supportingplate, the inner part of the third bearing is in interference connection with a fourth threaded rod, a second n-shaped mounting frame is welded to the top surface of the rectangular supporting plate,sliding grooves are formed in the inner walls of the two sides of the second n-shaped mounting frame, sliding blocks are arranged in the sliding grooves in a sliding mode, and a rectangular movable plate is integrally formed between the sliding blocks. According to the device, the inner rings and the outer rings of bearings with different sizes can be fixed conveniently, the grinding can be stabler, the use is flexible and convenient, the grinding is more sufficient, and the grinding quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of bearing processing, in particular to a grinding device for inner and outer rings of a bearing. Background technique [0002] Bearings are an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. The life of a rolling bearing is defined by the number of revolutions (or the number of hours of work at a certain speed): within this life Bearings should have initial fatigue damage (flaking or chipping) on ​​any of their bearing rings or rolling elements. However, no matter in the laboratory test or in actual use, it can be clearly seen that the actual life of bearings with the same appearance under the same working conditions is quite different. In addition, there are several different definitions of bearing "life", one of which is the so-called "operating life",...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a grinding device for inner and outer rings of bearings, which is used to solve the problem that the grinding device for inner and outer rings of bearings mentioned in the above background technology is inconvenient to fix the inner and outer rings of bearings with different sizes, the grinding is not stable enough, and the use is not flexible enough. At the same time, the grinding is not sufficient, which affects the quality of grinding and other issues.
