摘　　要：圆柱凸轮间歇运动机构具有结构简单、定位精度高、分度数较多等优点,在带有周期性停歇的自动机和半自动机中得到广泛的应用.采用等距曲面理论,推出圆柱凸轮间歇运动机构在满足各种多项式运动规律条件下圆柱分度凸轮廓形的曲面方程,直接求出凸轮机构中凸轮轮廓的所有数据,为空间凸轮轮廓计算奠定比较完整的理论基础.The intermittent motion mechanism of the cylindrical cam has the advantages of simple structure,high positioning accuracy, high degree of division, so it is widely used in automata and semi automata with periodic dwell. Cam profile surface equation of cylinder cam intermittent motion mechanism is introduced under a polynomial motion law, two polynomial motion law and five time polynomial motion law using isometric surface theory. This method can directly obtain all the data of the cam profile of the cam mechanism and lays a relatively complete theoretical foundation for the calculation of the spatial cam profile.
