适用于气冷式直排大气罗茨泵的一种转子型线

A rotor profile suitable for gas-cooled Roots pump

基于共轭曲线的基本啮合机理,给出了一种适用于气冷式直排大气罗茨泵的新型型线,另外还介绍了型线加工等方面的知识。

Based on the basic principle of engagement of conjugate tooth profiles,a new rotor profile is proposed to suit aircooled Roots pumps. In addition, the technologies of rotor profile machining are introduced briefly.
