摘　　要：基于精准的数学建模,分别构建了Hy-Vo齿形链链板-链轮啮合模型以及滚刀-链轮啮合模型,通过构造辅助链板,提出了一种基于啮合变异的Hy-Vo齿形链渐开线链轮变位系数的新算法。基于实例,计算了不同算法下的变位系数。基于链轮的范成法模拟加工技术,得到了不同算法下的实际加工链轮。通过测量不同半径下的齿宽,分析了不同算法下的实际齿形与设计齿形的齿形偏差。基于多体动力学仿真,分析了基于不同变位系数算法下的Hy-Vo齿形链传动系统的啮合特性。结果证明,这种Hy-Vo齿形链变位系数新算法可以有效降低Hy-Vo齿形链传动系统实际性能与理想性能之间的误差,不仅计算结果更加精准,并且适用于任何滚刀齿形角与链轮压力角变异组合。Based on the accurate mathematical model,the meshing model of Hy-Vo silent chain with theplate-sprocket subsystem and hob-sprocket subsystem is established. Through building the auxiliary chainplate,a new algorithm to calculate the profile shift coefficient of involute sprocket based on meshing variationfor Hy-Vo silent chain transmission system is proposed. Combined with a specific example,the profile shift co-efficients are calculated by the new algorithm and the classical algorithm. Based on the virtual machining tech-nology,the actual machining sprocket under different algorithms is obtained. Through measuring the toothwidths under different radius,the tooth profile deviations of actual sprocket are contrastingly analyzed. Based onthe multi-body dynamics simulation,the meshing characteristic of the Hy-Vo silent chain transmission systemsunder different algorithms are analyzed. The results show that the new algorithm could effectively decrease thesystem performance deviation between the ideal condition and the actual condition. In addition,the new algo-rithm could not only the calculation results are more accurate,but also applicable to any variation combinationof hub tooth angle and sprocket pressure angle.
