Low-noise and bearing-assembled ball feeder

Abstract

A low noise shaft assembling device, to add balls into the shaft through the shaft's ferrule, comprises platform, a pressure input device fixed on the platform and a shaft supporter. Two piston rods put pressure on the inner ferrule and outer ferrule of the shaft to make it elastic deformation and add balls into the shaft.

Description

Technical field: [0001] The invention belongs to the field of mechanical processing, and in particular relates to a low-noise bearing assembly and ball adding machine for adding rolling elements through elastic deformation of bearing rings. Background technique: [0002] During the assembly process of deep groove ball bearings, since nearly half of the models have ball angles exceeding 180°, when assembling this type of bearings, it is necessary to add the last rolling element (steel ball) through the elastic deformation of the bearing ring. . The traditional way of adding balls is to deform the outer rings of the two sets of bearings by colliding with each other, and then add the last steel ball. In this way, not only the labor intensity is high, but also the surface of the rolling elements will be damaged and the noise of the bearing will be affected, and sometimes the bearing ring will be damaged. Bruises affect the appearance quality. Invention content: [0003] The ...
