Embodiment Construction

[0021] During the use of self-lubricating bearings, according to different working environments, the requirements for the self-lubricating layer of self-lubricating bearings are also different. The requirements for the self-lubricating layer include low friction coefficient, high life, strong bearing capacity and high temperature resistance. The following describes the embodiments of the present invention according to the different requirements for the self-lubricating layer.

[0022] The steps to prepare a self-lubricating bearing with a low coefficient of friction are:

[0023] (1) Prepare a self-lubricating material based on polytetrafluoroethylene. The main component of the self-lubricating material is polytetrafluoroethylene, and it also contains bronze powder and carbon fiber. The proportions of the above three components are: polytetrafluoroethylene 70%-80%, bronze powder 10%-15%, Carbon fiber 10%-15%. When preparing the self-lubricating material, a certain ratio of p...

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. Background technique [0002] Joint bearing is one of the three basic components in industrial applications and plays an important role in national production. Its basic function is to provide force support and motion conversion for rotating machinery and oscillating machinery to ensure the normal operation of the equipment. In recent years, due to the needs of aviation, petroleum, chemical industry, power station, metallurgy, shipbuilding, nuclear energy, aerospace and other aspects, higher requirements have been put forward for self-lubricating bearings, which has prompted people to research and produce high-performance self-lubricating bearings. Load, long life, low friction high-performance self-lubricating bearings to shorten the gap in bearing manufacturing t...
