摘　　要：将"支撑函数法"向偏置式凹圆弧底、负半径滚子直动从动件盘形凸轮机构作延拓推广,巧妙和成功得到了凸轮轮廓曲率半径、外凸性判据、参数方程、周长和面积等一整套通用计算公式。不仅发展、深化了对新型凸轮机构的理解和认识,亦将支撑函数法延拓和推广成为一种为凹圆弧底和负半径滚子从动件盘形凸轮机构所共享的理论研究框架。The support function method is promoted to the disc cam mechanisms with arc-bottomed or negative radius translating follower offset from the axis. Then a series of general formulas are obtained,such as radius,parameter function,perimeter and area of the cams' profile. Not only the comprehension of these new types of mechanisms is improved,but also the support function method is promoted to them to make it become a general method to the disc cams.
