摘　　要：为发挥点啮合弧面凸轮的优点,在圆柱滚子弧面凸轮中利用球形滚子替代圆柱滚子与弧面凸轮进行啮合,实现可控点接触,避开了点接触弧面凸轮的加工难题。文中分析了圆柱滚子接触线上压力角、滚子和凸轮间作用力随滚子力臂长度的变化关系,进行了结构优化,利用ADAMS软件分析了机构的运动学特性,研究有利于点啮合弧面凸轮的推广和应用。In this article, in order to make full use of the advantages of the point-contact globoidal cam, the spherical roller is used to replace the cylindrical roller in the cylindrical roller’s globoidal cam to mesh with the globoidal cam, thus realizing the controllable point contact and avoiding the difficulty of the point-contact globoidal cam in machining. The analysis is conducted on the relationship between the pressure angle on the cylindrical roller’s contact line on one hand and the force between the roller and the cam changing with the length of the roller arm on the other hand;the structure is subject to optimization;the ADAMS software is used to explore the mechanism’s kinematic characteristics. This study is conducive to popularization and application of the point-meshing globoidal cams.
