摘　　要：在环面蜗杆螺旋线参数方程的建模基础上,论证并分析构建了平面包络环面蜗杆产形齿的特征模型,按此模型在MDT6.0环境中实现了平面包络环面蜗杆的三维建模.进而又分析讨论了平面二次包络环面蜗轮的特征模型与实体构建,实现了“平面二次包络环面蜗杆传动的参数化建模”.该方法简洁实用,三维实体具有真实的运动型面,能为数控加工提供精确的坐标参数,也能为平面二次包络环面蜗杆传动的性能优化奠定良好的基础.Based on the modeling and application of enveloping worm helix parameter equation, the generating gear characteristic model of planar enveloping worm was analyzed and the whole process demonstrated. According to this model, we reveal the 3D modeling of Planar Enveloping Worm. Furthermore, we discussed the application of the characteristic model of planar double-enveloping worm wheel and its entity construction, which carry out the transmission parameter modeling of Planar Double-Enveloping Worm. This method is concise and banausic. Meanwhile, this three-dimensional model has real motional profile, which can provide precise coordinate parameter for NC process. In addition, this method can spread to lay a good foundation for optimizing the transmission performance of Planar double-enveloping worm.
