Abstract

1318953 Rotary positive displacement machines LENINGRADSKY NAUCHNO-ISSLEDOVATELSKY I KONSTRUKTORSKY INSTITUT KHIMICHESKOGO MASHINOSTROENIA and SPETSIALNOE KONSTRUKTORSKOE BJURO PO KOMPRESSORESTROENIJU 29 Sept 1970 [20 Oct 1969] 46206/70 Heading F1F In a meshing-screw-rotor compressor, or motor, the torque on the female rotor 3 and pulsating loads on the bearings and synchronizing gears are reduced by the profile of each tooth 4 of the male rotor 2 having epicycloidal portions A, C 1 and A 1 C<SP>1</SP> 1 , an hypotrochoidal portion C 1 D 1 and an arc of a circle C<SP>1</SP> 1 D 1 . The portion A 1 C<SP>1</SP> 1 may be replaced by an extension of the arc C<SP>1</SP> 1 D 1 to the point A 1 , this arc having a radius which is less than that of the tip circle 9 and may be greater than the tooth height with the centre of curvature inside of the pitch circle 7. The portions A 1 C 1 and A 1 C<SP>1</SP> 1 are the loci of points A 2 and A 2 <SP>1</SP>, respectively, on the pitch circle 6. The portion C 1 D 1 is the focus of a point S on an extended radius of a circle 8 rolling on the circle 7.
