摘要

为实现扭叶罗茨泵无脉动无轴向力及其轻量化所期望的更大容积利用率与更小内泄漏目的，提出了内共轭轮廓段采用半叶节圆弧的弦高线和叶顶径向等圆弧间隙结构的高形扭叶构造方法，并基于扭叶容积副与斜齿动力副间的无轴向力耦合关系，给出了二者的无轴向力耦合设计方法和实例分析。结果表明，扭叶转子副端面的平－凸共轭及其顶部等圆弧间隙的轮廓构造能有效抑制共轭泄漏和径向泄漏，实现1.6的更大形状系数和0.58的更大容积利用系数；转子两端面60°的扭叶错角能实现理论的无脉动性能；20°~25°的螺旋角能同时满足扭叶转子与标准斜齿轮等端面节圆半径的同轴要求且方法简单。研究为开发高质量泵提供了一定的理论基础。

Abstract

In order to realize non-flow ripple and non-axial force of roots pump with helical rotor and greater capacity utilization and smaller internal leakage as desired by its lightweight，for high cross shape coefficient of rotor，a construction method for chord height line of pitch arc of half lobe as internal conjugate profile segment and top profile segment with radial equal arc gap is proposed，from coupled relation without axial force between volume pair with helical rotor and power pair with helical gear，its coupled design method with non-axial force is derived and an example is given. All results show that plane-convex conjugate gap and top equal arc gap can effectively restrain conjugate leakage and radial leakage，and cause larger shape coefficient of 1.6 and larger volume utilization coefficient of 0.58 to come true，helical angle of 60° can realize theoretical non-flow ripple，and coaxial design with equal cross pitch radius of helical rotor and standard helical gear can be derived from helical angle of 20°~25°，and the coaxial design method is simple，etc. It provides a theoretical basis for future high quality development of roots pump.
