Polymer self-lubricating thin layer composite axle sleeve and its preparation method

Abstract

The invention discloses a polymer self-lubrication thin layer composite shaft sleeve and the preparation method, which is rolled by a support skeleton made of metal mesh and a polymer composite. The formation of the metal mesh can be mesh-weaving forming, two-way stretching forming, punch forming or other forming modes; the shape of the mesh can be lozenge, hexagon, round or other shapes. The invention of shaft sleeve has excellent wear resistance, water corrosion resistance and good self-lubricating property and is especially suitable to be applied in the self-lubrication liner bushings of the automobile door hinge, footrest, joy stick and automatic door and window system.

Description

technical field

[0001] The invention relates to a polymer self-lubricating thin-layer composite shaft sleeve and a preparation method thereof, in particular to a multi-layer self-lubricating shaft sleeve formed by sintering and rolling metal mesh and polymer composite materials and a preparation method thereof. Background technique

[0002] With the rapid development of the automobile industry, higher requirements have been put forward for the performance of the moving friction pair parts. It is required that the material not only has good self-lubricating performance and wear resistance, but also has good high temperature resistance and load resistance. ability. Metal-polymer multilayer composite materials have good thermal conductivity, high load-carrying capacity, excellent wear resistance and self-lubricating properties, and are highly valued by people, and are widely used in automotive connecting rods, shock absorbers and hydraulic cylinders. However, in order to meet ...
