Wear Properties of Dry Bearing Liners at Ambient and Elevated Temperatures - A Preliminary Survey.

摘要

This Report describes a preliminary investigation into the wear behaviour of thin, PTFE containing, bearing liners using a reciprocating line contact apparatus to provide accelerated wear data in a few hours, as opposed to the several months needed on more conventional, full-scale bearing test rigs. The investigation had three main objectives:- (a) To compare the wear properties of a wide range of materials in constant conditions of sliding. (b) To examine the effect of some of the parameters likely to influence wear, particularly load and temperature. (c) To assess the changes in wear behaviour of one particular type of material by varying the type of matrix resin, reinforcement, and cure-cyclic conditions.
