摘　　要：应用单参数曲面族包络面理论分析和研究圆锥滚子直动从动件圆锥凸轮机构,导出了圆锥凸轮廓面的数学表达式。以此为基础,建立了采用尺寸等于或小于圆锥滚子尺寸刀具加工圆锥凸轮时的刀具刀尖轨迹方程。The research in this paper introduces the profile determination of the conical cam with a translating conical follower mechanism based on the theory of envelopes for 1 parametr family of surfaces.The analytical expression of cam profile is established once the follower motion program has been given.With the lbtained analytical profile expression,the required cutter path is provided.The size of the cutter can be identical to or smaller than that of the conical follower.
