摘要

针对非等模数非等压力角行星齿轮传动系统,建立了多自由度平移-扭转振动的非线性动力学模型。考虑到齿轮副齿侧间隙、系统综合误差和齿轮副模数与压力角的不相等,计算了系统的均载系数并对由它们所引起的系统不均载特性进行了动力学分析。获得了误差一定且齿侧间隙改变时,啮合副的动载荷曲线与均载系数间的变化关系。讨论了齿轮副模数和压力角分别不同时,系统均载系数的变化幅度。研究表明:随着齿轮副压力角选择范围的扩大,系统均载系数有着较大幅度的变化;齿侧间隙使系统的啮合副处于不同冲击状态,不同冲击状态对系统的均载性能有着重要的影响。

Abstract

A Translation-torsion coupled nonlinear dynamic analysis model with multi-degree of freedom was established for planetary gear train system with non-equivalent modulus and pressure angle. And with the gear backlashes, comprehensive errors and the non-equivalent modulus and the pressure angle of gear pair considered, the load sharing coefficient of the gear train was formulated. The dynamic characteristics of sharing load caused by them were analyzed. Some relations between the dynamic load curve of the gear pair and the load sharing coefficient were obtained due to certain errors and changes of backlash. The range of the change of the system loading coefficient was discussed with the variation of gear modulus and pressure angle. The results show that load sharing coefficient has larger variation as to expand the range of selection pressure angle of gear pair, and the different impact of meshing pair caused by backlashes has important influences on the sharing performance of the planetary gear train system.
