摘要:
A centrifugal compressor (22) comprises: a case (160) having a suction port (24) and a discharge port (26); an impeller (162, 164) mounted for rotation about an impeller axis (500) by a plurality of bearings (80, 82); and a motor (34) coupled to the impeller to drive rotation of the impeller about the impeller axis. The bearings each comprise: an inner race (200); an outer race (202); and rolling elements (204) between the inner race and outer race. T the bearings each comprising: an inner race (200); an outer race (202); and rolling elements (204) between the inner race and outer race. The outer race of each bearing is mounted for radial displacement relative to the case and is surrounded by an associated chamber (224); and the chambers are coupled to a port (92) on the compressor.
