摘　　要：合理的节曲线设计是可用于低速大扭矩液压马达的变中心距非圆行星齿轮机构正常工作的关键。非圆太阳轮的节曲线由椭圆演变而来,非圆内齿圈的节曲线通过非圆行星齿轮机构的转化机构求解。在理论分析的基础上,采用Matlab为工具,以某型变中心距非圆行星齿轮机构为例对其节曲线进行了求解。Appropriate pitch curve designing is a key of regularly working for non- circular planetary gear mechanism with variable center distance which can be used in low speed high torque hydraulic motor. The pitch curve of sun gear is evolved from ellipse and that of internal gear is solved through the invert mechanism of the non - circular planetary gear mechanism. The pitch curve of a non- circular planetary gear mechanism with variable center distance is solved with Matlab based on the theory analysis.
