发动机正时张紧器O形密封圈挤出失效研究

Research of Extrusion Failure on O-ring of Engine Timing Chain Tensioner

基于某发动机正时张紧器O形圈的一实际问题的分析处理,对O形圈典型的挤出失效展开了研究,分析了嵌件间隙、圆角、材料特性、压缩率、压力循环等各因子对挤出失效的影响与作用。

Based on the analysis and solution implementation for an O-ring extrusion failure of an engine timing chain Tensioner, this paper investigated this typical failure of O-ring and discussed the influence or affection of some known factors, such as seal quad clearance, fillet, material characteristics of O-ring, compression ratio of O-ring, pressure cycle etc on the failure.
