摘　　要：内啮合步进波动机构是一种具有中间挠性件的间歇运动机构,适用于中、低速传动,具有良好的运动特性。文章运用微分几何及啮合原理对该机构进行了运动分析,推导了角度、角速度、角加速度、压力角的传递函数公式以及曲率表达式,并对输入传统运动规律时的输出情况进行对比,得出余弦运动规律的运动性能最好的结论,为该机构的推广应用提供了理论基础。Stepping-wave-cam mechanism with internal-meshing cams is kind of intermittent mechanism of middle flexible appendages. It is particularly adaptable in slowand high-duty circumstances,due to its excellent kinematic feature. Based on differential geometry and meshing principle,By means of the kinematic analysis on the mechanism,the transmit functions and curvature formulae of the angle,angular velocity,angular acceleration,pressure angle were derived. Comparison of the output results while inputting the traditional motion law,the best conclusion of motion performance of the motion lawof cosine has been drawn.The paper introduces theory and computing technology,in order to provide scientific basis for popularization and application of this mechanism.
