摘要

针对微线段行星齿轮传动精度中回差计算困难的问题，考虑了齿轮固有误差、装配误差及齿轮时变啮合刚度的影响，提出了基于微线段齿轮侧隙的行星齿轮传动回差模型，通过蒙特卡洛模拟法，针对3K-I型行星轮系，计算所得微线段行星齿轮的理论回差值比渐开线行星齿轮的回差值小约5.92%。在同等情况下进行试验验证，结果表明，试验所得微线段行星齿轮回差值在理论模型计算范围内，且微线段行星齿轮回差值较渐开线行星齿轮的回差值小6.25%，验证了该微线段行星齿轮传动回差模型的正确性。

Abstract

Aiming at the difficult about lost motion calculation of micro-segment planetary gear transmission accuracy. Considering the influence of gear natural error， assembly error and the time-varying mesh stiffness of gears， the lost motion model of planetary gear transmission is proposed based on the backlash of micro-segment gear. Aiming at 3K-I planetary gear train， the theoretical calculation lost motion of micro-segment gear is 5.92% smaller than involute gear by Monte Carlo simulation. Experiment under the same conditions shows that the lost motion of micro-segment planetary gear is within the theoretical model calculation and the lost motion of micro-segment planetary gear is 6.25% smaller than involute gear， which proves that the lost motion model of micro-segment planetary gear is correct.
