Embodiment Construction
[0070] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0071] Such as figure 1 Shown is the profile diagram of the claw rotor of a proposed claw vacuum pump. According to the counterclockwise direction, the rotor profiles are: the first elliptical arc envelope line AB, the first elliptical arc BC, and the claw top circle Arc CD, second elliptical arc DE, third elliptical arc envelope EF, pitch circle arc FG, third elliptical arc GH, second elliptical arc envelope HI and claw bottom arc IA; between adjacent curves All smooth connections, no non-smooth connection points; the mechanical properties, meshing performance and sealing performance of the claw rotor are improved.
[0072] Such as figure 2 As shown, it is the profile line generation diagram of the left rotor of the claw rotor of a claw vacuum pump proposed, and the rotor profile generation method is as follows:
[0073] 1) Take the origin O as the...
