Abstract

The invention relates to a thin wall bearing, in particular to a heavy-duty thin wall deep groove ball bearing. A bearing machining method comprises five processes of machining an outer ring, machining an inner ring, machining a retainer, machining a seal ring, and assembling the outer ring, the inner ring, the retainer and the seal ring. The method has the advantages that: the grinding accuracy of the inner and outer rings, the deformation of the retainer and a space between the retainer and the seal ring are ensured, so that the inner and outer rings, the retainer and the seal ring are not contacted with each other and do not generate friction, and the service life of the bearing is prolonged; and moreover, noise is avoided, and the requirement on a heavy load of the bearing is met under the condition that the overall size of the bearing is not changed.

Description

technical field [0001] The invention relates to a processing method of a bearing, in particular to a processing method of a heavy-duty thin-walled deep groove ball bearing. Background technique [0002] With the advancement of science and technology, both electronic products and mechanical products are gradually miniaturized and lightweight, resulting in the gradual miniaturization and lightweight of bearings in related equipment, and the requirements for precision are getting higher and higher. In order to obtain bearings Low friction torque, high rigidity, good rotation accuracy, use small outer diameter steel balls, but if the cage and sealing ring around the steel balls maintain the original structure, they will touch each other and cause friction, resulting in damage, eventually resulting in The whole bearing needs to be replaced frequently, and it will generate noise while friction. Contents of the invention [0003] The purpose of the present invention is to provid...
