本文通过把椭圆齿轮机构与正齿轮机构和正弦机构串联组合，进行运动分析，齿形解析，按所需运动规律进行计算机辅助设计（CAD）和计算机动态传动模拟，实现了其它串联机构难以实现的某些特殊运动要求，充实扩大了机械传动的运动性能和用途．同时为串联机构的组合、优化设计提高了一种可靠有效的研究方法． In this paper, by combining the oval gear mechanism with the spur gear mechanism and the sine mechanism in series, the kinematics analysis and the tooth profile analysis are carried out. The computer aided design (CAD) and the computer dynamic transmission simulation are carried out according to the required motion rules, which makes it difficult to realize in other series mechanisms Some special sports requirements, substantial expansion of the mechanical transmission of sports performance and use. At the same time, the combination of series mechanism and optimization design improve a reliable and effective research method.
