Angular contact ball bearing assembly fixture

Abstract

The invention relates to an angular contact ball bearing assembly fixture. When angular contact ball bearing assembling is carried out, a heated bearing outer ring is placed on an outer ring supporting step of a base assembly, a holder is placed on a holder supporting part of the base assembly, then a steel ball is placed on a supporting part of an elastic supporting piece, the steel ball is keptin a pocket, a bearing inner ring is finally installed in an inner hole defined by a holder ball in a pressing manner, the elastic supporting piece is compressed and deformed in the inner ring pressing fit process, and interference in the inner ring pressing fit process is avoided. In the using process of the assembly fixture, the supporting part of the elastic supporting piece is kept in the pocket of the holder, a lubrication agent is not needed for pasting the steel ball and the holder together, and lubrication agent washing after assembly in place is not needed; and when the fixture is used for assembling, operation is simple and convenient, and the problem that when an existing fixture is used for assembling, a lubrication agent is needed, and consequently the assembly efficiency is low is solved.

Description

technical field [0001] The invention relates to an angular contact ball bearing assembly tool. Background technique [0002] When assembling the angular contact ball bearing with the inner ring of the lock, the outer ring is usually heated first to expand the outer ring, and then the outer ring is removed, and the rolling elements are quickly bonded to the cage pocket and the cage pocket with Vaseline or other viscous medium. The space between the channels of the outer ring, and then the inner ring is pressed in to complete the assembly. In the assembly process of angular contact ball bearings, special tooling is required to ensure assembly accuracy and reduce assembly difficulty. For example, the Chinese patent with the authorized notification number CN 205978134 U discloses an angular contact ball bearing assembly tool, which includes a base and a mandrel installed in the inner hole of the base. During the assembly process of the bearing, the heated bearing Put the outer...
