摘　　要：分析了蜗杆压缩机啮合副中星轮齿面的组成,给出了包络面和轨迹面方程,讨论了星轮齿廓的径向滚切干涉。指出星轮齿廓无法采用精确展成加工获得,并提出了用极限轨迹面代替包络面的星轮加工方法,建立了星轮加工原理误差的计算方法和优化控制模型。理论研究及试验表明:提出的星轮齿廓加工方法,具有刀具易于制作、加工精度易于控制、生产成本低等优点。The composition of gaterotor profile of worm com- , pressor is analyzed, the formulae of enveloping surface and tracking surface of gaterotor tooth are proposed, radial bobbing interference of gaterotor is discussed. The research shows that the gaterotor can not be generated by wormgear hob, a machining method using extreme tracking surface to approach enveloping one is proposed, calculating method and controlling model of the principle error of the gaterotor are established. Theoretical research and test show that the method proposed in this paper is characterized by simpler in cutter structure, easier in manufacture accuracy control and lower production cost.
