[0030] Specific implementation plan
[0031] See figure 1 . The new tooth profile of the screw rotor of the twin-screw compressor of the present invention includes a male rotor tooth profile 1 and a female rotor tooth profile 2. The tooth shapes of the end faces of the male rotor and the female rotor are asymmetrical. The number of teeth on the female rotor is 1 or 2 more than the number of teeth on the male rotor. In this embodiment, the teeth on the male rotor and the female rotor adopt five pairs of six asymmetric tooth shapes, where the male rotor has five teeth and the female rotor has six teeth. The teeth of the male rotor 1 and the female rotor 2 are formed by smoothly connecting six segments of curves. These curves include ellipses, arcs and their envelopes, without any sharp points or sharp edges. Normally, the female rotor is driven by the male rotor, and the steering is as follows figure 1 Shown. Take center line O 1 O 2 It is the dividing line, the lower half is the...
