Title:
CENTRIFUGAL COMPRESSOR
Document Type and Number:
Japanese Patent JP2020105985
Kind Code:
A
Abstract:
To reduce agitation resistance during rotation of a ring member.SOLUTION: A partition wall 90 is disposed between a ring member 62 and a bottom 24 of a main body part 25 in a speed-increasing gear chamber S2. Further, a centrifugal compressor 10 comprises an introduction path 98 for guiding an oil in an agitation region 96 that is a region positioned closer to the ring member 62 than the partition wall 90 in the speed-increasing gear chamber S2 to a storage region 97 that is a region positioned closer to the bottom 24 of the main body part 25 than the partition wall 90 in the speed-increasing gear chamber S2. The oil which is agitated by rotation of the ring member 62 and collides with an inner peripheral surface of a speed-increasing gear housing 23 partially flows toward the partition wall 90 and is guided through the introduction path 98 to the storage region 97. oil stored in the storage region 97 is hard to be agitated by the rotation of the ring member 62, thereby reducing an absolute quantity of the oil to be agitated by the ring member 62.SELECTED DRAWING: Figure 2
