摘　　要：综合考虑了三环减速机的输入轴和支承轴的弹性、行星轴承的弹性、输出轴轴承的弹性、齿轮啮合弹性以及输入轴和支承轴偏心套的偏心误差和分度误差 ,建立了三环减速机的弹性动力学方程。分析了三环减速机的固有频率。The governing equations for elasto-dynamic analysis of three-ring reducers are derived with consideration of many factors including the elasticity of input and support shaft, the elasticity of bearings in the planetary and driven shaft, the elasticity of meshing gears and errors of the eccentric cranks in indexing and eccentricity. The eigenfrequency of a three-ring reducer is also calculated.
