In this paper, the principle of involute meshing is used to derive the relationship between the dimensions of different involute Roots rotor rotors at different tool angles α. The influence of different tool angles on pump performance and selection principle are analyzed. Line Cartesian coordinates unfolding, for the production of templates and rotor manufacturing conditions to provide the conditions. Through calculating the volumetric utilization factor of the pump with different tool angles α, the theoretical basis for calculating the capacity and geometrical size of the pump is provided for the design, and a discussion program is proposed for the processing of the involute rotor with the extension method. In order to seek a way to improve the accuracy and efficiency of rotor machining. Convenient for the designer, the paper lists the commonly used tool angle α various calculations table. This article is available for Roots vacuum pumps and Roots blower design workers and production workers for reference.
