摘要
以啮合理论为基础,导出了蜗式凸轮机构从动件(即分度转盘)在凸轮实际轮廓和实际机构尺寸诸因素的影响下,分度误差的计算公式。并结合实例,运用变形梯形加速度运动规律,通过微机计算,得出了该凸轮机构从动件的分度误差曲线。
Based on meshing theory, a formula is derived for calculating index error of worm-type cam follower(i.e.Tindex plate)under influence of actual worm-type cam profile and dimensions. With an example given, index error curve is obtained by applying acceleration law of deformed trapeze on a computer.
