Abstract:
A screw compressor that enhances performance of a compressor main unit and a motor is provided. The screw compressor includes an oil-injected compressor main unit 1 that compresses air with injecting oil in a compression chamber 9 and an axial-gap motor 2 that drives the compressor main unit 1. A male rotor 7 of the compressor main unit 1 has a suction-side shaft portion 17 connected coaxially with a rotor shaft 3 of the motor 2. The screw compressor further includes a suction-side bearing 20 that rotatably supports the suction-side shaft portion 17 of the male rotor 7. The suction-side bearing 20 restricts axial movement of the suction-side shaft portion 17 and bears a radial load and axial loads in both directions.
