摘　　要：将"支撑线"、"支撑函数"等概念向新型凸轮机构做引伸和推广,得到了凸轮轮廓曲率半径、外凸判据、参数方程、周长和面积等一整套通用计算公式,将"支撑函数法"发展成为平底/负半径滚子从动件盘形凸轮机构共享的研究框架。Let the concepts of ＇＂ supporting line＂ and ＂supporting function＂ be extended and popularized to the new typed cam mechanism, a full set of generalized calculation formulae was obtained for the radius of curvature, convex criterion, parametric equation, circumference and area etc. of cam profile. Let the ＂supporting function algorithm＂ be developed as a framework of research sharable for the flat bottomed/cam mechanism with negative radius roller follower.
