BEARING DEVICE, BEARING UNIT, AND ROTARY MACHINE

摘要

A bearing device (10) is provided with bearing pads (13) placed around a rotating shaft (3) to support a thrust collar (12) and carrier rings (15), each of which houses the bearing pads and is supported by a casing (20). And, a supported surface (15a) which is supported by the casing on the carrier ring is a curved surface which is raised at least along one direction orthogonal to the rotating shaft at a substantially constant curvature around the center of gravity (G) of the thrust collar.
