摘　　要：在原有圆柱凸轮机构基础上提出了一种大小滚子圆柱分度凸轮机构,利用小滚子销轴的弹性变形来约束机构的轴向可能发生的振动。建立了小滚子销轴的力学分析模型,改变不同的参数条件来分析销轴的变形,并确定在某一条件下的销轴的弹性形变量,获得相关的参数表,为以后机构的精确建模及动力学分析提供依据。The type of cylindrical index cam mechanism with different size roller is proposed on the basic of original cylindrical mechanism. Using the elastic deformation of small roller pin to constraint mechanism of axial vibration may occur. The small roller pin mechanics analysis model is established, by changing different parameters to analyze the deformation of the pin roller and to determine the deformation of pin roller on a certain condition. By the work above, the parameter table is obtained and the basis for accurate modeling and dynamics analysis in the future is provided.
