同向双螺杆几何设计计算软件的应用

Application of the Calculation Software for Co-rotating Twin S crew Geometry Design

通过算例介绍了同向双螺杆几何设计计算软件的功能。该软件除构造元件几何形状及间隙修正外,将同一双螺杆上所有规格的螺杆元件作为一个整体进行综合设计计算,以保证各元件之间的平滑接合。由此提出端面接合误差修正的问题以及捏合盘设计计算的新方法。可根据不同需要计算轴截面、横截面及斜截面中螺杆元件曲线的坐标值,并以数据库的形式存储。该软件所具备的功能是双螺杆CAD/CAM的基础。

The functions of the calculation software for a corotating twin screw geometry design are introduced by means of showing a calculation example.The essential w ork of the software is the screw element profile construction and the screw clea rance calculation.The software features the integrated design for all the elemen ts of a twin screw extruder to make them configured together smoothly.So the iss ue of the joint error amendment and a new method about the kneading block design are presented.The data of the screw profiles in axis section,transverse section ,and oblique section can be calculated and then be stored in a data base.These f unctions are the bases on which the CAD and CAM systems for twin screws can be e stablished.
