Abstract

The invention provides a high thermal conductivity wear-resistant self-lubricating liner. The high thermal conductivity wear-resistant self-lubricating liner is obtained by immersing a fiber fabric in an impregnating solution and then forming it by hot pressing; the fiber fabric is made of the following parts by weight The components are braided: 25-50 parts of polytetrafluoroethylene fiber, 25-50 parts of aramid fiber, 5-20 parts of graphite fiber, and 10-25 parts of low-melting polyamide fiber. The present invention also provides a preparation method of the high thermal conductivity and wear-resistant self-lubricating liner. The high thermal conductivity and wear-resistant self-lubricating liner prepared by the method of the present invention has excellent wear resistance, heat resistance, corrosion resistance, Self-lubricating, homogeneous, dense and high thermal conductivity, suitable for use as self-lubricating liners for plain bearings.

Description

technical field [0001] The invention belongs to the technical field of self-lubricating materials, and in particular relates to a high thermal conductivity and wear-resistant self-lubricating liner and a preparation method thereof. Background technique [0002] Spherical joint bearing is a kind of sliding bearing, the structure is relatively simple, mainly composed of an outer ring with an inner spherical surface and an inner ring with an outer spherical surface, self-lubricating spherical joint bearings are inlaid or bonded between the inner and outer rings Layers of self-lubricating liners. This layer of self-lubricating liner is the key factor to ensure that the joint bearing has excellent performance such as strong load capacity, impact resistance and long life in many high-tech fields such as aerospace and aviation. [0003] Common fiber fabric pads are woven from high-performance aramid fiber and polytetrafluoroethylene fiber, in which polytetrafluoroethylene fiber ac...
