Abstract
A centrifugal compressor includes an electric motor coupled to a low-speed shaft, an impeller, and a speed increaser. The speed increaser includes a ring member, a high-speed shaft, rollers, a speed increaser housing member, a discharge passage, and a partition. The ring member includes a circumferential wall and is rotated when the low-speed shaft rotates. The high-speed shaft is coupled to the impeller. The rollers are located between the circumferential wall and the high-speed shaft. The speed increaser housing member stores oil. The discharge passage discharges oil out of the ring member. The partition is located between the speed increaser housing member and the circumferential wall in the radial direction. Power is transmitted from the low-speed shaft to the high-speed shaft by the ring member and the rollers.
