摘要
介绍了双螺杆空气压缩机转子型线设计的研究现状及主要方法。重点研究基于啮合线反求转子型线的新方法,根据阴阳螺杆转子坐标系建立了啮合线坐标系,研究了啮合线为点、直线和曲线时反求转子型线的方法,最后得出不同啮合线下的转子型线的通用计算公式,为双螺杆空气压缩机转子型线的设计提供了参考。
The research status and main methods of the rotor profile design of rotor of two-screw air compressor are introduced.This paper focuses on the new method of rotor wire based on meshing line, and according to the coordinate system of yin and yang screw rotor, the meshing line coordinate system is established, and study the method of finding the rotor profile when the meshing line is the point, the straight line and the curve.Finally, a general formula for calculating the rotor profile under different meshing lines is obtained, which provides a reference for the design of the rotor profile of rotor of two-screw air compressor.
