| 摘 要： | 为了提高国产正时链条的性能，研究了05BT—1汽车发动机正时链的磨损失效机理以及销轴、套筒和滚子等元件摩擦表面的磨损形貌特征．结果表明，汽车发动机正时链的主要磨损机制是疲劳磨损，销轴、套筒零件表面的裂纹生成、扩展与剥落是其主要磨损失效机理．因此，保证滚子零件具有足够的强度与塑性，并采用合理的成形工艺，是提高滚子零件多冲抗力的有效方法．

| Abstract: | The paper studied the fault mechanism of the automotive engine timing chain as well as the worn surface morphology of the rubbing pair of bush and pin and roller based on the analysis of test. The results show that the main wear mechanism of automotive engine chain is form, extend and flaking of crack for top layer of pin and bush. The effective methods that increases resistance to multicycle impact for roller are to ensure that the roller has sufficient strength and plasticity and to adopt suitable shaped technics. |
