摘要： A rotor profile for screw compressors is disclosed. The rotor profile is shown in a latitudinal cross-section taken along a line extending in a direction perpendicular to rotor axes, and is applied to male and female rotors used in a screw compressor having a housing defining an actuating space therein, the male rotor being rotatably set in the actuating space and having spiral teeth and roots defined between the teeth, and the female rotor being set in the actuating space to rotatably engage with the male rotor and having spiral teeth and roots defined between the teeth. The rotor profile comprises a first curve F-G determined as a circular arc and inscribed in an addendum circle of the female rotor at a point "G" around a trailing end of each tooth of the female rotor, and a second curve determined by a hyperbola function r=(epsilon.K)/(1-epsilon.cos theta), wherein 1.1

摘要： PURPOSE: A profile of a rotor for a screw compressor is provided to minimize the area of a leakage triangle while enlarging the minimum pressure angle of a processing tool. CONSTITUTION: A profile of a rotor for a screw compressor is used to the screw compressor having a housing with working space, a male rotor(1) rotating in the working space and forming grooves between spiral teeth, and a female rotor(2) rotating while engaging with the male rotor, and forming grooves between teeth. The profile is indicated in the axial direction. The profile includes a circular curve, F-G, internally touching with the addendum circle(Af) of the female rotor at a point G, and a curve portion composed of a hyperbola function, r=(epsilon times K)/(1-epsilon times COS theta) of 1.1
