凸轮压力角与从动杆运动规律及基圆大小的关系

The relationship between cam’s pressure-angle and driven-perch’s movement rules and benchmark-circularity’s size

通过对凸轮轮廓曲线上各点压力角的分析,运用应用程序Excel准确地绘制出了凸轮在不同的从动杆运动规律情况下压力角的变化曲线和不同基圆半径时压力角的变化曲线,为设计凸轮机构时保证机构具有良好的传动性提供了一个可靠的参考依据。

By analyzing pressure-angle of each point on the cam's outline curve, we accurately draw pressure-angle's changing curve under conditions of different driven-perch's movement rules and different benchmark-circularity's radius respectively by using application of Excel. This provides a reliable reference basis for ensuring the machine's nicer driving performance when we design cam machines.
