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．
Single screw compressor round table secondary enveloping mesh has a good tooth surface properties, but the processing of star wheel hob making more difficult. By optimizing the position of the blade, the crowning error of limited blade hobbing can be controlled within the allowable range, thereby reducing the number of blades and reducing the difficulty of making the hobbed hob. The tooth surface equation of the secondary package to the gear pair, the cutting edge curve of the inserts, the calculation method of the crown error and the calculation of the parameters of the insert pocket are given. In addition, an example is given.
