罗茨泵转子实际型线公式的推导与计算

Deduction and Calculation of the Practical Linear Formular of Roots Pump Rotor

本文对渐开线型线罗茨泵转子的理论型线、实际型线公式做了新的推导。给出了转 子型线在直角坐标系第一象限内三段曲线的坐标方程式，列出了计算机程序框图，给 出了实例结果。这对罗茨泵转子的加工和检查具有一定的指导和帮助作用。

In this paper, a new deduction on the theoretical linear formula and the practical one of the involute, linear roots pump motor was made. Give the coordinate equation of rotor linear .on the 3-section curve within the first quadrant of the rectangular coordinate, show the program block diagram of computer, and give the results of the sample. It is useful and helpful to produce and check for the roots pump.
