Method for manufacturing high-accuracy self-lubrication bearings by transfer film technology

Abstract

The invention discloses a method for manufacturing high-accuracy self-lubrication bearings by a transfer film technology, relates to the technical field of manufacturing of bearings and aims at solving the problem that the manufacturing accuracy of self-lubrication layers of the conventional self-lubrication bearings is difficult to control. The method for manufacturing the high-accuracy self-lubrication bearings comprises the following steps: selecting proper self-lubrication materials according to different working environments, making the self-lubrication materials into transfer film grinding wheels and applying the transfer film grinding wheels to a grinding machine to be used as the grinding wheels of the grinding machine; then grinding inner spherical surfaces of outer rings of joint bearings by the transfer film grinding wheels to obtain self-lubrication layers on the inner spherical surfaces of the outer rings of the joint bearings; and finally pressing inner rings of the joint bearings into the outer rings of the joint bearings to obtain the self-lubrication bearings which meet the requirements. The manufacturing accuracy is high.

Description

technical field [0001] The invention relates to the technical field of bearing manufacturing, in particular to a method for preparing high-precision self-lubricating bearings by utilizing transfer film technology.
