Title:
SCREW COMPRESSOR AND METHOD FOR ASSEMBLING SAME
Document Type and Number:
WIPO Patent Application WO/2024/034213
Kind Code:
A1
Abstract:
This screw compressor comprises male and female rotors that are accommodated in a casing so as to be in mesh with each other and be capable of rotating about parallel rotational axes. The male and female rotors each include a rotor teeth portion having spiral teeth, a suction-side shaft portion, and a discharge-side shaft portion. The rotor teeth portions of the male and female rotors are each configured such that a lead angle changes. Each of the male and female rotors has, on either the suction-side shaft portion or the discharge-side shaft portion, an engaging portion that engages with a positioning jig used during assembly in order to restrict the distance between the rotational axes of the male and female rotors.
