摘　　要：介绍凸轮激波滚动活齿传动的传动原理及结构特点,推导中心内齿轮的理论和工作齿形方程。基于弹性小变形及变形协调假设给出理论状态下啮合力分析的模型和算法,结合啮合力计算示例对提出的方法进行说明,并初步获得此类传动装置的啮合力分布特点。得到的啮合力分析结果可作为凸轮激波滚动活齿传动的结构设计、效率与刚度估计以及强度校核的分析基础。The drive principle and structural characteristics of the movable rolling tooth transmission with cam actuating are intro- duced, the theoretical and working teeth profile equations of central inner gear are deduced. Based on the hypothesis of stretch small distortion and distortion congruity, the model and algorithm of meshing force analysis under theoretical conditions are proposed, the presented method is illustrated through an example of meshing force calculation, and the distributing characteristic of meshing forces of this type of transmission device is preliminarily acquired. The acquired result of meshing force analysis can be adopted as the analytical base for structure design, efficiency and stiffness estimation, as well as intension checkout of the movable rolling tooth transmission with cam actuating.
