【摘要】 单螺杆压缩机的圆台二次包络啮合副具有较好的齿面性质，但加工星轮用的滚刀的制作较困难．通过优化刀片的位置，将有限刀片滚削时产生的凸度误差控制在允许的范围内，从而减少了刀片数，降低了镶片星轮滚刀的制作难度．给出了圆台二次包给啮合副的齿面方程、镶嵌刀片的刃口曲线、凸度误差的计算方法和刀片槽有关参数的计算．另外，还给出了一个算例．更多还原

【Abstract】 The working-surface characters of a conical surface two-envelope engagement pair usedin a single screw compressor are very good. But it is difficult to machine its inserted star rotorhob. In the paper,the convex error caused by finite blade number,number of inserted blades,and thus difficulty in machining star rotor hob are decreased. The tooth surface equation of aconical surface two-envelope engagement pair,inserted blade curves,method calculating convex error and other parameters and an example are presented更多还原
