摘　　要：通过对正时链条失效模式分析,找到了导致链条伸长的主要因素;通过采用加速疲劳试验台进行验证,渗钒销轴链条的抗磨损性能优于碳氮共渗和渗铬销轴链条;采用渗钒销轴链条后,解决了某发动机项目开发初期的链条伸长问题。该试验方法和结论对发动机链条系统开发和应用方面具有一定的参考意义。Through the analysis of the chain failure mode,the main factors that causing the chain elonga-tion is found. Through the validation on the acceleration-fatigue test rig,the chain using vanadinizing pins ismore better than carbon-nitrogen and chromizing pins on the chain wear-resistant characteristics. After usingvanadinizing pin chain,the problems of the engine project which has the chain severely worn issues is solved.The conclusions and test method has a certain kind of reference on the chain system development and applica-tion on the engine.
