摘　　要：通过对移动从动件凸轮轮廓曲线的几何分析,运用三心定理得出凸轮压力角的计算公式,用Excel准确计算出凸轮轮廓曲线上各点的压力角后运用图表分析不同运动规律、不同升程及不同偏心距的情况下凸轮轮廓曲线上各点压力角的变化规律。Through geometric analysis of transforming follower cam contour curves,the calculation formula of cam pressure angles is obtained by three core theorem,and then the cam contour curve pressure angles of every point are accurately worked out by Excel,and its variation is analyzed by using charts under the circumstances of different motion law,cam lift and eccentricity.
