Bearing bush separation clamp

Abstract

The invention provides a bearing bush separation clamp which can simultaneously realize axial pull-out and circumferential rotation loosening of a bush and realize torsion and pull-out separation of the bush and a bearing outer ring. The clamp comprises a bearing outer ring mounting seat and a bush mounting seat, wherein the bearing outer ring mounting seat is a hollow sleeve with one end open andthe other end closed, a clamping rod A is arranged on the outer end surface of the closed end of the bearing outer ring mounting seat, a to-be-separated test bearing is sleeved in the bearing outer ring mounting seat, and a bearing outer ring of the test bearing is connected with the bearing outer ring mounting seat; one end of the bush mounting seat is provided with a clamping rod B, and the other end of the bush mounting seat extends into the bush of the test bearing and is connected with the bush. In addition, the clamp finely adjusts the mounting depth of the positioning pin for connecting the bush and the bush mounting seat through the positioning plug, so that the bush can be reliably separated from the bearing outer ring.

Description

technical field [0001] The invention relates to a fixture, in particular to a bearing bush separating fixture, which belongs to the field of sliding bearing testing. Background technique [0002] Sliding bearings are widely used in various mechanical products, many of which are assembled by interference fit between bushings and outer rings. This kind of bearing has a simple structure and is widely used. However, there may be cases where the bushing separates from the outer ring during use. In order to conduct a systematic study of this situation, a special separation fixture is required for the bushing loosening experimental test. [0003] The requirements for the bush separation fixture are mainly reflected in: (1) It can realize the torsion separation and pull-out separation of the bush and the outer ring; (2) The structure is simple, easy to process and operate; (3) It is economical and cheap . [0004] At present, there are few such fixtures, and they are mainly axia...

AI Technical Summary

Problems solved by technology

The disadvantage of this type of fixture is that it cannot realize the torsional moment test of the bush separation, that is, the existing bearing bush separation fixture is difficult to simultaneously test the axial pull-out and circumferential rotation loosening of the bush, and it is difficult to meet the test requirements under complex working conditions.
