THRUST BALL-BEARING RETAINER TO BALL SECESSION PREVENTION

摘要

The present invention relates to a retainer of a thrust ball bearing which is adopted on the shaft of an electric motor such as an industrial machinery and is mainly subjected to a thrust load on the shaft. In the thrust bearing retainer, which has an integral bottom surface through which a plurality of bearing seating holes are drilled to form an annular shape with a predetermined diameter, and a shaft is formed in the hollow portion of the inner diameter surface, a planar ball is seated on the outer diameter surface and the inner diameter surface of the retainer. Forming a bent portion is bent so as to be opposed to each other in an arced direction to the inner side to be mounted to prevent separation of the ball, the ball mounted to the retainer of the thrust ball bearing is easily removed from the retainer when used for a long time by the thrust load Ball release prevention truss to prevent detachment Ball bearing retainer.
