提升汽车摩托车发动机强化正时齿形链的回转疲劳性能将有助于提高发动机正时强化齿形链的使用寿命,使发动机正时链与发动机同寿命;通过强化齿形链链板冲压、挤孔和热处理工艺以及强化预拉工艺等手段大幅提升正时链回转疲劳性能。并对提升正时链回转疲劳性能的措施进行分析和试验验证,提升了齿形链的整体质量水平。 Improving the fatigue performance of the motor and motorcycle engine to enhance the timing fatigue of the toothed chain will help to improve the service life of the toothed chain of the engine timing enhancement and make the engine timing chain and the engine have the same lifespan. By strengthening the toothed chain link plate stamping, Extrusion and heat treatment process and strengthen the pre-pull technology and other means to significantly improve the timing chain rotation fatigue performance. And to improve the timing chain rotation fatigue performance measures to analyze and test validation, to enhance the overall quality of the tooth-shaped chain level.
