摘要

设计研究了一种新式分度凸轮-行星齿轮复合机构。其输入轴与输出轴同轴放置，输入轴与摆杆固连，摆杆与行星齿轮轴铰接，行星齿轮、两个摆臂以及行星齿轮轴固连。摆杆随输入轴转动，两个摆杆上的滚子分别与两个凸轮保持接触，接触点随摆杆转动不断变化，摆臂相对摆杆发生相对转动，带动与其相连的行星轮摆动。最终实现中心轮的间歇运动，即分度运动。定义了机构运动的工况参数，根据具体参数推导了凸轮的实际轮廓线方程，完成机构的三维建模与运动仿真，验证了设计建模过程的正确性。

Abstract

A new type of indexing cam-planetary gear composite mechanism is designed and studied. The input shaft is coaxial with the output shaft， the input shaft is fixedly connected to the swing rod， the swing rod is hinged to the planetary gear shaft， and the planetary gear， the two swing arms and the planetary gear shaft are fixedly connected. The swinging rod rotates with the input shaft， and the rollers on the two swinging rods are kept in contact with the two cams respectively. The contact point changes continuously with the rotation of the swinging rod， and the swinging arm rotates relative to the swinging rod to drive the planetary wheel connected thereto to swing. Finally， the intermittent movement of the center wheel is realized， that is， the indexing movement. The working condition parameters of the mechanism motion are defined. According to the specific parameters， the actual contour equation of the cam is designed， and the 3D modeling and motion simulation of the mechanism are completed， which verifies the correctness of the design modeling process.
