负半径滚子摆动推杆盘形凸轮机构的凸轮轮廓设计

Design of disc cam with negative radius oscillating-roller-follower

针对传统微分几何包络法和"支撑函数法"在求解凸轮轮廓方面暴露出的缺点和不足,通过引据"定比分点方法",研究并解决了P型/F型、同摆式/异摆式负半径滚子摆动推杆盘形凸轮机构的凸轮理论/工作轮廓方程问题,为新型凸轮机构的进一步研究与推广应用奠定了理论基础。

Traditional differential-geometry-envelope and supporting function methods have many defects to solve cam profiles. Definite-proportion and division-point method was used to solve the problems of theoretical and actual contours of P-type and F-type, and the tilting and different tilting disc-cam mechanisms with negative radius oscillating-roller-follower, The results provide a theoretical basis for further research and application of the new type cam mechanisms.
