The technical characteristics of the invention is that: the rotor end face tooth profile contains four, five or six sections of tooth curves with the circular nature; when it has five sections, addendum circular arcs and dedendum circles are added to the addendum or the dedendum of the rotor; when it has six sections, both the addendum circular arcs and the dedendum circles are added to the addendum and the dedendum of the rotor at the same time, to form four different combination schemes; there are common tangents at the connection points of the two adjacent teeth forming curves, which has a smooth tooth-profile without cusp, a high-wearing feature, a long life of the rotor, a small leakage triangle, and a good sealing property.
本发明的技术特征是：转子端面齿型是包含四段、五段或六段圆弧性质的齿曲线；当为五段时，在转子的齿顶或齿根加上齿顶圆弧或齿根圆弧，当为六段时，在转子的齿顶和齿根同时加上齿顶圆弧和齿根圆弧，形成四种不同的齿型组合方案；相邻的两组成齿曲线的连接点处具有公切线，齿型光滑，没有尖点，耐磨性好，转子的使用寿命长，泄漏三角形小，密封性好。
