球钢支座的摩擦副材料性能及测试方法比较

摘要:

两个既直接接触又产生相对摩擦运动的物体所构成的体系称为摩擦副。在球钢支座中，摩擦副是关键组成部件之一，其材料的摩擦性能和力学性能一定程度上决定了球钢支座整体性能的优劣。本文主要介绍了国内外摩擦副材料的应用前景及关键的性能指标，以及各国规范对指标检测方法的异同。

Abstract:

Sliding surface is combination of a pair of flat or curved surfaces of different materials which allow relative displacements. Sliding surface is one of the key components of spherical bearings, and the tribological and mechanical properties of the sliding material determine the overall performance of the spherical bearing to a certain extent. This paper mainly introduces the application prospect and key performance parameters of sliding materials at home and abroad, as well as the similarities and differences of testing methods of the testing parameters in the codes of various countries.
