摘要
为了建立双螺杆输送机螺纹几何轮廓的数学模型，使用相对运动分析的方法，得出了修正后螺纹轮廓表面上任意一点的数学表达式组；结论是利用该组数学表达式，可直接求得螺纹轴截面内的几何形状。
In order to establish the mathematical model of a twin screw's geometry, the research results in a group of formulas which describe the screw surface after analyzing the twin screw's relative movement The conclusion is that with the formulas, screw's geometry in axial section plane can be got directly [
