摘　　要：环面涡杆涡轮三维构建属复杂曲面造型.在环面涡杆螺旋线解析方程建模和渐开面包络环面涡杆三维实体构建的基础上,分析讨论了渐开面二次包络环面涡轮的几何特征.应用涡杆特征模型,采用有限次数逻辑运算逼近方法完成渐开面二次包络环面涡轮实体构建,实现了渐开面二次包络环面涡轮副传动的组建.Enveloping worm wheel molding belongs to the modeling of complex surface. Based on the modeling of enveloping worm helix analytical equation and constructing of TI - worm, the article analyzes geometry characteristics of the involute helicoids double-enveloping worm wheel, demonstrates the whole process by means of finite time Boolean calculation approach method with characteristic model of TI - worm, and establishes the involute helicoids double-enveloping worm gear pairs. This method is concise and practical. Meanwhile, this three-dimensional model has real motional profile, which can provide precise coordinate parameter for NC process.
