構成したことを特徴とする回転電機の軸受装置。In a bearing device for a rotating electric machine in which a bearing that supports the vicinity of both ends of the rotor shaft is mounted in a bearing box and is locked with a bearing cover, there is a gap between the outer circumferential part of the bearing and the inner circumferential part of the bearing box. A predetermined gap is provided so that the bearing can rotate slightly, and a large expansion coefficient support member is arranged on the inner wall of the bearing lid so as to have a predetermined gap with the outer peripheral side of the bearing at room temperature. , characterized in that it is configured such that the outer circumferential side surface of the bearing is pressed by thermal expansion deformation of the large expansion coefficient support member as the temperature rises during rotation of the rotating electric machine, thereby stopping the slight rotation of the bearing. Bearing devices for rotating electric machines.
