摘　　要：运用空间啮合原理推导出斜平面二次包络环面蜗杆副的齿面方程。根据蜗杆副的几何特征,确定建模需要的接触区边界方程。对典型传动的蜗轮齿面的二次接触区的信息点呈现不等距分布的情况,采用网格划分的方法构建齿面。该方法实用,为数控加工提供精确的数据点,保证了后续的有限元分析及其啮合性能分析的准确性。The equations of tapered plane double enveloping worm gear pair are deduced by using gear special meshing theory.According to the geometric feature of worm gear pair,the contact zone boundary equation that is the need of solid modeling is determined.Under the phenomenon that the information point shows unequal distribution in twice contact area of primary-type drive.By utilizing the method of grid division,the worm surface is constructed.This method can provide precise data for NC machining and also guarantee for accuracy in finite element analysis and meshing performance analysis.
