FIELD: machine building.
SUBSTANCE: screw compressor rotor profile comprises two parallel mutually enveloping screw surfaces. Compressor drive rotor teeth profile sections are made up of curves of elongated cycloid circumscribed by path of fixed point spaced from the center of generating cycle rolling without slip on straight line located in system of coordinates of the rotor.
EFFECT: reduced gas leaks at suction side, lower fluid friction between surfaces in contact, higher compressor efficiency.
