摘要： A rotor pair for a high-pressure screw compressor having main and secondary rotors, the main rotor having essentially convex teeth arranged outside its reference circle and the secondary rotor having essentially concave teeth arranged inside its reference circle. The distance between the axes of the rotors, which limits the size of the possible bearings, is enlarged only by increasing the number of teeth and the diameter of the secondary rotor so that it is larger than the main rotor.
