圆柱凸轮间歇运动机构的摩擦学分析

Tribology Analysis about Interruption Moving Mechanism of Cylinder Cam

本文提出圆柱凸轮间歇运动机构运转的可靠性与该机构的摩擦学特性有关,并对其进行深入的摩擦学分析.分析表明,该机构圆柱凸轮和从动滚子表面间的摩擦是在表面接触疲劳情况下的滚滑摩擦;两表面间主要产生表面疲劳磨损,同时伴有粘附磨损,表面疲劳磨损是该摩擦副损坏的主要原因;理论上两表面间的润滑状态是同时要考虑油膜动压效应和挤压效应的非稳态弹流润滑,但实际工作过程中,也会有边界润滑或部分流体润滑状态存在.

In this paper, the relation between the moving reliability of cylinder cam interruption mechanism and it' s tribology characteristics is showed, and the tribology analysis is carried out.
