摘　　要：采用Visual Basic工具对大型机械CAD软件SolidWorks进行了二次开发,完成了<135>型三螺杆泵主、从杆的参数化设计。在此基础上提取螺杆的法截面和纵截面数据并于理论值进行对比分析得出二者误差很小,可以直接从螺杆三维图得到螺杆法、纵截面数据。此种获得螺杆法、纵截面数据的方法快捷、方便,避免了推到公式的繁琐。此方法可验证一些推导得出的复杂型面公式的正确性。Uses Visual Basic to the secondary development of SolidWorks, achieving the parametric design for 〈135〉 three screw pump central rotor and idler rotor. On this basis, extracting the data of the central rotor and idler rotor law section and longitudinal section surface contour, and compared with the standard data, then obtaining the largest error between the extracting data and theoretically correct value. As the error is small. Through the central rotor and idler rotor three-dimensional model, can directly obtain the central rotor and idler rotor law section and longitudinal section surface contour. This method is fast, convenient and avoiding the tedious pushed to the formula. At the same time, the method can also verify some complex shape formula is right or not.
