Abstract (en)
[origin: EP0104265A1] In a screw compressor including a female rotor and a male rotor rotating while meshing with each other, the rotor tooth form (8) of one of the female and male rotors meshing with each other without any clearance therebetween in normal temperature condition is used as a basic tooth form for obtaining a rotor tooth form (9) produced by deformation on account of thermal expansion during operation. The tooth form thus obtained is used for generating another rotor tooth form (10), and the rotor tooth form thus generated is used to obtain a rotor tooth form which is a normal temperature version of the thermally deformed tooth form, to thereby use the rotor tooth form of the normal temperature version for the other of the female and male rotors. In deciding the rotor tooth form, the backlash of synchronizing means may also be taken into cinsideration in addition to the influences of thermal expansion.
