Abstract

In this paper, an experimental simulation method was used for evaluating the tribofilm formation in rolling/sliding contact at different points in the line of action. A ball-on-disc test method was employed by which the pressure and slide to roll ratio of gear contact could be simulated. In order to reach a general conclusion, four different oils and two surface roughness were involved in the experiments. The tribofilm evolution was captured using spacer layer interferometry method, and the correlation of tribofilm with the location at the line of action was studied. Results showed that there is a threshold pressure for the tribofilm formation around which the tribofilm growth rate is maximum. Above this threshold pressure, the tribofilm formation is not stable, and the wear is dominant. Below this threshold pressure, the tribofilm growth rate rises by increasing the pressure and the gear contact is safely protected by a stable tribofilm.

沿作用线模拟齿轮接触的摩擦膜形成

摘要

在本文中，一种实验模拟方法用于评估在作用线上不同点滚动/滑动接触中摩擦膜的形成。采用球盘试验方法，通过该方法可以模拟齿轮接触的压力和滑动滚动比。为了得出一般性结论，实验中涉及四种不同的油和两种表面粗糙度。使用间隔层干涉测量法捕获摩擦膜演变，并研究摩擦膜与作用线位置的相关性。结果表明，摩擦膜形成存在一个阈值压力，在该压力附近摩擦膜生长速率最大。高于此阈值压力，摩擦膜的形成不稳定，磨损占主导地位。低于这个阈值压力，
