Research on Timing Chain Wear Performance of the Engine

Abstract

Through the analysis of the chain failure mode， the main factors that causing the chain elongation is found. Through the validation on the acceleration-fatigue test rig， the chain using vanadinizing pins is more better than carbon-nitrogen and chromizing pins on the chain wear-resistant characteristics. After using vanadinizing 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 application on the engine.
