摘要
球齿轮是一种不同于传统齿轮的新型齿轮,球齿轮机构具有2个传动自由度,它用来传递二维回转运动。阐述用Pro/E实现渐开线球齿轮机构的精确三维造型方法,并对球齿轮机构进行运动学仿真。仿真结果说明球齿轮机构可在两球体之间实现精确、连续的球面纯滚运动,因而可作为从动件输出轴的空间姿态需要精确控制的执行机构。
The involute spherical gear is a new kind of gear which is different from traditional gear. The involute spherical gear mechanism has twos degree of freedom and it can be used to deliver 2D motion. This text synopsis elaborated to use the Pro/ E to realize the involute spherical gear mechanism＇s accurated modeling and kinetics simulation. The result of kinetics simulation illustrated the involute spherical gear mechanism can realize precisions and continuous surface of sphere rolls motion purely between two spherical gears. As a result, it can be the performance mechanism of the accurate space attitude control of the follower output shaft.
