摘　　要：针对目前高速灌装机中弧面凸轮设计过程复杂,造型精度低及转盘间歇分度不平稳的问题,根据弧面凸轮与转盘的运动关系及灌装分度要求,建立弧面凸轮的轮廓曲面数学模型,采用分段建模对弧面凸轮进行造型研究。然后对所设计凸轮的轮廓曲面进行了曲面分析、干涉检查和运动学分析,结果表明弧面凸轮的造型具有较高的造型精度,可满足高速灌装设计要求。In order to solve the problems and low accuracy modeling in globoidal cam designing as well as instability during high-speed filling,the mathematical model of profile surface of the globoidal cam was set up based on filling requirements and motion relationship between globoidal cam and indexing plate.The segmentation modeling is applied to create 3Dsolid model of globoidal cam.Surface analysis,inference inspection and kinematic analysis are studied for the created 3D model of globoidal cam,and the results showed that a high modeling accuracy was obtained,which may meet the design requirements of globoidal cam device for high-speed filling.
