【摘要】 介绍了传统渐开线齿形存在的不足之处,并研究出一种新型的罗茨真空泵转子型线,根据齿轮啮合原理与参数方程相结合的方法,准确、真实地描述了的新型转子型线的完整齿廓。解决了传统渐开线齿型存在的型线干涉、困气等问题,使两转子在运行的过程中达到很好的啮合效果。为新型转子型线的数字化设计,啮合分析、动态仿真、运动学和动力学分析提供了新的理论依据。更多还原

【Abstract】 Presents the conventional involute profiles have some problems ,and study a new rotor profile of Roots vacuum pump. It’s whole tooth profile is described exactly by combining the meshing principle of gears with parameter equation. The performance of meshing of two rotors is improved without profile interference and packet gas, which are the problems of conventional involute profiles. The work provides new theoretical basis for digital design of new rotor profile, its meshing analysis, dynamic emulation, kinematics and dynamics analysis. The research has practical value.更多还原
