计算和分析了用锥面砂轮和平面砂轮磨削加工的二次包络环面蜗杆副的啮合性能及蜗杆的根切和齿顶变尖特性，结果表明，当锥形砂轮直径较大时，两种砂轮加工出的蜗杆极为近似，因此可采用大直径锥形砂轮代替平面砂轮近似加工平面包络蜗杆，以提高磨削效率
The meshing performance of the worm gear pair with conical surface grinding wheel and plane grinding wheel and the tip cutting and tooth tip creasing characteristics of the worm were calculated and analyzed. The results show that when the diameter of the cone grinding wheel is large, Two kinds of grinding wheels are very similar to the worm, so large-diameter conical grinding wheel can be used instead of the plane grinding wheel to process the planar enveloping worm to improve the grinding efficiency
