摘　　要：针对RV减速器的传动结构特点,应用Pro/E参数化建模技术,建立了RV减速器的三维实体模型,并以RV-40E为例,采用ADAMS软件对一级传动和二级传动进行运动学与动力学耦合仿真,分析了一级传动和二级传动的动力学特性对RV减速器传动特性的影响,并对其进行整机动力学分析。结果表明:一二两级传动对曲柄轴转速波动均有影响;二级传动导致输出轴转速波动的幅度远大于一级传动;针齿与摆线轮之间的啮合力因曲柄轴自转(摆线轮公转)而呈周期性波动,啮合力幅值随摆线轮修形量的增加而增大;曲拐轴承转动副受力巨大,易导致轴承损坏。研究结果对RV减速器的产品化设计具有重要的参考价值。According to the characteristic of the transmission structural of RV reducer, using RV-40E as an example, three- dimensional parametric models was constructed by Pro/E software. The coupling of kinematics and dynamics of the first transmission and the second transmission were simuhtted by ADAMS software. The effect of dynamics of the two transmissions on characteristic of the transmission of RV reducer and the dynamics of integral machine were analyzed The results show that the crankshaft speed fluctuation is mainly due to the first transmission and the second transmission; the degree to the second transmission affects the output speed fluctuation is far more than the first transmission,＂ the mesh force between pin gear and cycloidal gear fluctuate periodically, which is due to the crankshaft rotation （the cyclodial gear revolution）; as cyclodial gear modification increases, the amplitude value of mesh force increases also; The stress of revolute pair of cranked bearing is huge, which will lead to the bearing destroy. The research results are extremely signifiwant to the product design of R V reducer.
