谐波齿轮振动探析

Research About Vibration of Harmonic Drives

本文运用弹性动力学理论分析了谐波齿轮中柔轮的振动原理，指出柔轮的工作原理和受力特点是谐波齿轮产生具有输入转速偶数倍谐波成分振动的基本原因。谐波齿轮传动的振动会直接影响精密机械传动链的运动平稳性。

Starting from elastic-dynamic equations of motion for flexspline, the paperanalyses the vibration of harmonic drives andindicates that the main reason is the workingprinciple and the status of flexspline, The vibration frequencies ate the resonant frequencies even times of the input rotative speed.Vibration of harmonic drives has direct effectson the moving stability of precise mechanicaltransmission chain.
