摘要

非圆齿轮行星轮系是非圆齿轮液压电动机的核心部件，其节曲线设计是整体结构设计的关键。针对4~6阶非圆齿轮行星轮系节曲线的参数不唯一、设计困难等问题，基于4~6阶非圆齿轮行星轮系节曲线的设计方法，选取偏心率作为控制参数，设计出不同非圆齿轮行星轮系的节曲线；对比分析了偏心率对非圆齿轮行星轮系运动特性的影响。结果表明，非圆齿轮行星轮系在传动过程中，行星轮中心加速度和行星轮角加速度均会出现突变，突变的位置均在内齿圈向径最大位置处，且随着节曲线偏心率的增大，行星轮中心加速度和行星轮角加速度的突变值均为增加趋势。

Abstract

Non-circular gear planetary gear train is the core component of non-circular gear hydraulic motor， and its pitch curve design is the key to the overall structure design. Aiming at the problems of non-circular gear planetary gear train pitch curve of order 4-6， which is not unique and difficult to design， based on the design method of pitch curve of 4-6 order non-circular gear planetary gear train， the eccentricity is selected as the control parameter to design different pitch curves of non-circular gear planetary gear train. The influence of eccentricity on the motion characteristics of non-circular gear planetary gear train is compared and analyzed. The results show that， in the process of non-circular gear planetary gear train transmission， the center acceleration and angular acceleration of planetary gear will have a sudden change， and the mutation positions are at the maximum position of inner gear ring radial diameter， and with the increase of eccentricity of pitch curve， the abrupt values of center acceleration and angular acceleration of planetary gear increase.
