摘要
传动误差和回程误差是精密传动装置中两个最重要的精度指标。分析闭环伺服系统前向通道上精密传动装置的传动误差和回程误差对伺服系统性能的影响,提出计算方法。在此基础上,对谐波齿轮传动装置与行星齿轮传动装置进行实例对比分析,指出在闭环伺服系统中,谐波齿轮传动装置比行星齿轮传动装置的回程误差小,但谐波齿轮传动装置的传动误差对系统的影响大于行星齿轮传动装置。
The quality of mechanical drive decides the performance of the servo system,the driving error and hysterisis error are the most important precision index. The influences of the driving error and hysterisis error to the closed servo system were analyzed and their calculation methods have been put forward. The harmonic drive and planetary gear transmission were carried on as examples for comparison,which lead to the results that the driving error of harmonic drive is greater than that of planetary gear transmission and the hysterisis error is smaller than the latter.
