摘要
提出齿形链当量链板的概念,分析了内-外复合啮合齿形链与渐开线链轮的啮合关系;指出与链轮渐开线齿廓啮合的链板内侧齿廓的正确形式,提出了一种基于二次变异的齿形链链板内侧齿廓优化设计方法;建立齿形链传动系统的多体动力学模型,对比分析了基于不同设计方法的齿形链传动系统。仿真结果表明,基于二次变异的内-外复合啮合齿形链内侧齿廓优化设计,可以显著减小齿形链传动系统的多边形效应以及啮合冲击。
The conception of the equivalent silent chain plate is proposed,the meshing relations between the inner-outer compound meshing silent chain and involute sprocket are analyzed.The correct form of silent chain plate inner profile for meshing with the sprocket involute profile is pointed out,the optimization design method of silent chain plate inner profile based on the secondary variation is proposed.The multi-body dynamics models of silent chain transmission system are established,and the silent chain transmission system based on different design methods is compared and analyzed.The results show that the optimization design of inner-outer compound meshing silent chain plate inner profile based on the secondary variation could effectively reduce the polygon effect and meshing impact of silent chain transmission system.
