摘　　要：随着机械产品复杂化和多样化的发展,高性能非匀速传动机构的需求日益增多。文中融合端面活齿机构和非圆齿轮的传动特性,提出了具有大刚度和高承载能力的非匀速端面活齿传动机构。首先阐明了非匀速端面活齿的传动原理,给出了根据传动比规律,构建齿廓方程的一般方法,并建立了非匀速端面活齿连续传动的判别公式;然后推导出了该机构的压力角和传动效率公式,为其性能分析提供了理论依据;最后以实现高阶椭圆齿轮传动比为例,对非匀速端面活齿机构进行仿真设计及性能分析,从而验证了传动理论的正确性。With development of complicated and diversified machine, then need of mechanism with high performance is increasing. An end face gear with movable teeth is presented based on non-circular gear, which have properties of large stiffness, high load strength and variable transmission ratio. The transmissionprinciple and tooth equation of the mechanism are introduced, with continuous transmission condition discussed. Then, the equations of the pressure angle and the efficiency are deduced to provide theoretical basis for the performance analysis. Finally, a simulation of the mechanism is made to achieve the transmission ratio of a pair of high-order elliptical gears, which validates the correctness of the transmission theory.
