Abstract
A screw compressorincludes a compressor main body, a motor, and a gearbox. The compressor main bodyincludes screw rotors, and, rotor casingsandaccommodating therein the screw rotors, and, and main body casingsandaccommodating therein the rotor casingsand, the main body casings being provided with first flangesandon respective ends thereof. The motordrives the screw rotors, andvia gearsand. The gearboxhas an attachment surface Son which the first flangeto the main body casingsandis attached, accommodates therein the gearsand, and has a substantially rectangular shape. In a state where the compressor main bodyis attached to the gearbox, a part of the first flangeextends to an outside of the attachment surface S, and projection regions of the rotor casingsandonto the attachment surface S exist within the attachment surface S. In this way, vibrations of the screw compressorcan be reduced.
