摘　　要：基于摆线凸轮机构所具有的优异传动特性,设计了一种新齿型活齿传动机构-内摆线凸轮活齿传动。基于内摆线生成法、转速变换和齿形包络法推导出激波轮和中心轮理论及工作齿形,利用仿真软件分析了二齿差和三齿差的中心轮理论齿形的曲率半径。在避免齿廓干涉条件下,选择合理的活齿半径,同时给出了齿廓平滑完整无顶切的激波轮和中心轮的理论齿形并分析了齿形参数对中心轮齿形的影响。Base on the advantages of cycloid cam mechanism, designing a new hypocycloidal tooth drive. With the hypocycloidal method,speed conversion and envelope method, derive the tooth of theory and working of shock cam and Center Gear, Using simulation software to analyze the center wheel theory radius of curvature of two or three teeth difference. Select the appropriate range of tooth radius at the conditions of avoiding tooth interference. Meanwhile draw a theoretical tooth of shock cam and center wheel with smooth and complete. Finally, the effects on the profile＇s geometry with the involved parameters are analyzed.
