Abstract

1294210 Rotary positive-displacement machines LENINGRADSKY NAUCHNO - ISSLEDOVATELSKY I KONSTRUKTORSKY INSTITUT KHIMICHESKOGO MASHINOSTROENIA 29 Sept 1970 46205/70 Heading F1F In a screw compressor, or motor, having male and female rotors 2, 3 the profile of each tooth 4 of the male rotor comprises identical epicycloidal portions A 1 C 1 interconnected by a hypotrochoidal portion C 1 D 1 C 1 . Each of the portions A 1 C 1 is a part of the locus of a point As on the pitch circle 6 of the female rotor, the point A 1 being on the pitch circle 7 of the male rotor. The portion C 1 D 1 C 1 is a part of the locus of a point S on an extended radius of a circle 8 rolling on the inner side of the pitch circle 7.
