摘　　要：通过将负半径滚子引入德国进口高速印刷机机构中,首次提出一种新型的作平面运动负半径滚子推杆-盘形凸轮组合机构。针对包络法和"支撑函数法"求解凸轮轮廓暴露出的缺点不足,通过引据"定比分点方法",系统地研究解决了作平面运动负半径滚子推杆-盘形凸轮组合机构的凸轮理论/工作轮廓设计问题,为新型盘形凸轮-连杆组合机构的研究、推广应用奠定了重要理论基础。By introducing negative radius roller to a German high speed printing machine, this paper firstly, proposed a new type of negative radius roller putter-disc cam combination mechanisms moving in planar general motion. Traditional Differential Geometry envelope method and ＂ supporting function method＂ have many defects and shortcomings in solving the cam profiles. Using by the ＂definite proportion and division point＂ method, the theoretical and actual contours of negative radius roller putter-disc cam combination mechanisms moving in planar general motion are systematically studied and solved. The results obtained in this paper could lay an important foundation for further research and application of the novel disc cam - link combination mechanisms.
