【摘要】 运用相对运动法导出了平行分度凸轮廓形方程,通过相对运动的分析,运用等距曲线原理,导出了平行分度凸轮实际压力角的计算公式,运用matlab6.0对实际压力角进行了仿真分析,并与传统的压力角简化计算进行了比较,压力角简化计算的结果与实际压力角的差距较大,工程实际中不应继续沿用简化计算。更多还原

【Abstract】 The shape of parallel indexing cam organ was studied by a relative motion method. Based on the relative motion model, the pressure-angle expressions were derived with special coordinate systems and isometric curve theory. The actual pressure angle was analyzed with matlab and was compared with an approximate pressure angle. The conclusion that the calculation of an approximate pressure angle was not available was reached.更多还原
