摘　　要：针对变中心距非圆行星齿轮机构应用于液压马达中独特的优点,介绍变中心距非圆行星齿轮机构的原理和组成,建立以SOK型非圆行星液压马达作为对象的分析模型,在理论分析的基础上,采用Matlab和CAXA工具,以46型变中心距非圆行星齿轮机构为例对其节曲线进行求解并进行三维造型,生成的齿轮三维实体可用于装配设计、运动仿真及计算机辅助教学中.Aimed at the particular advantage of the variable center distance non-circular planetary gear mechanism in its application in hydraulic motor, its operation principle and principle and composition were introduced and then an analytical model of SOK-type hydraulic motor with non-circular planet gear was es- tablished. On the basis of theoretical analysis and by using softwares Matlab and CAXA, the solution of pitch curve and generation of 3-D modeling were conducted for 46-type planet gear mechanism with varia- ble center distance. The three-dimensional entity of generated gears could be used for assembly design, motion simulation and computer-assisted teaching.
