摘　　要：平面二次包络环面蜗轮副三维实体属复杂曲面造型,文章在坐标变换公式的基础上,讨论了环面蜗杆螺旋齿面方程,建立了环面蜗杆螺旋线参数方程,并用VBA编程建模.按此建模,用平面包络环面蜗杆产型齿的特征模型,在M DT 6.0三维绘图软件环境中实现平面包络环面蜗杆和二次包络蜗轮副的三维建模,并以断面图检验了其良好的接触啮合状态.所生成的实体模型具有给定参数的数字信息,可用于此类环面蜗杆的齿廓形状分析和进一步应用研究.Planar double enveloping worm gear pairs molding belongs to modeling of complex surface. Based on the coordinate change equation, the Enveloping worm helix tooth surface equation is discussed. Enveloping worm helix parameter equation is founded. Modeling is programmed-with VBA. According to this model, the 3D modeling of Planar double enveloping worm gear pairs is build with TP- worm characteristic model in MDT6.0 drawing software. Its good contact state is validated with section drawing. The founded entity model has the numerical information of the given parameter. It could be used for tooth profile analysis of the enveloping worm and further application study.
