摘要
圆弧-圆弧包络线是螺杆转子中应用最广泛的基本组成段。阐述了圆弧-圆弧包络线的生成原理,分别采用几何法和基于齿廓法线法的解析法,推导出圆弧-圆弧包络线啮合副的型线方程及其啮合线方程,并以SRM圆弧对称齿形、SRM-D齿形等为例,展示了各种圆弧-圆弧包络线啮合副的典型组合及其改进过程,为转子型线的后续演化提供参考。
This paper demonstrates the generating principle of circular-circular envelope curve, which is the most widely used basic segments of the screw rotor profiles.The geometric method and analytical method based on tooth profile normal line method are used individually to derivate the profile equation and its meshing line equation of the meshing pair of circular-circular envelope curve.Furthermore, to provide reference for further development of rotor profile, we illustrate several typical examples and development of different combinations of the meshing pairs, such as SRM Symmetric Profile, SRM-D Profile, etc.
