摘要
介绍了自洁型同向双螺杆的基本几何关系 ,分析了同向双螺杆几何设计计算软件的功能。该软件以设计同向双螺杆螺纹元件及捏合盘外廓曲面为基础 ,采用法向修正方法计算间隙。提出了端面接合误差的概念并实现了对该误差的修正算法 ,可根据不同需要计算轴截面、横截面及斜截面中螺纹曲线的数据。
This paper briefly introduces the essential geometry of self wiping co rotating twin screw,analyzes the functions of the co rotating twin screw geometry design calculation software The main functions of the software involve the calculation of the screw elements geometry and normal direction amendment The conception of the joint error amendment is presented,and relative algorithm is developed The software could be applied to the calculation of the data of the screw profiles in axis section,transverse section,and oblique section,according to different needs These functions are the base of CAD and CAM systems for twin screws
