Title: ROTARY MACHINE
Abstract:
The present invention is provided with: bearings (16) that each include an inner ring (16A) that is fixed to an outer periphery (11a) of a rotator (11), an outer ring (16B) that is disposed at an outer side of the inner ring (16A), and a plurality of rolling elements (16C) that are interposed between the inner ring (16A) and the outer ring (16B); bearing boxes (13, 15) that are disposed at outer sides of the bearings (16) and to which the outer rings (16B) are fixed; a casing (18) that is disposed outside the bearing boxes (13, 15) and to which the bearing boxes (13, 15) are fixed; and concave portions (35, 36) that are provided inside the casing (18) as temperature-difference suppression mechanisms (19) that reduce the difference between the temperature of the outer ring (16B) and the temperature of the inner ring (16A).
