Abstract
A centrifugal compressor includes a rotary shaft, an electric motor, which has a rotor, a tubular boss, through which the rotary shaft extends, and a radial bearing. The rotor has a rotor end face, which is an end face in an axial direction of the rotary shaft. The boss has a boss end face, which is an end face in the axial direction of the rotary shaft. The rotor end face and the boss end face face each other in the axial direction of the rotary shaft. A thrust bearing is arranged between the rotor end face and the boss end face to receive thrust force generated by rotation of the impeller.
Claims8
A centrifugal compressor comprising:
- a rotary shaft;
- an electric motor, which includes a rotor attached to the rotary shaft and rotates the rotary shaft;
- an impeller, which rotates as the rotary shaft rotates, thereby compressing fluid;
- a housing, which accommodates the rotary shaft, the electric motor, and the impeller;
- a tubular boss, which is provided in the housing and through which the rotary shaft extends;
- and
- a radial bearing, which is provided between the boss and the rotary shaft and rotationally supports the rotary shaft, wherein
- the rotor has a rotor end face, which is an end face in an axial direction of the rotary shaft,
- the boss has a boss end face, which is an end face in the axial direction of the rotary shaft,
- the rotor end face and the boss end face face each other in the axial direction of the rotary shaft, and
- the centrifugal compressor comprises a thrust bearing, which is arranged between the rotor end face and the boss end face and receives thrust force generated by rotation of the impeller.
