摘要： A fluid film bearing includes a plurality of bearing pads that are arranged in a circumferential direction of a rotating body that rotates about an axis, and that support the rotating body via a fluid film, wherein the bearing pad includes a base layer made of metal, an elastic layer that is layered on the rotating body side of the base layer, and that is made of an elastically deformable elastic material, a sliding layer that is layered on the rotating body side of the elastic layer, and that opposes the rotating body and is made of a bearing material, and a metal plate that is layered between the elastic layer and the sliding layer, and that is more rigid than the elastic layer and the sliding layer.

摘要： An oil bath type bearing device which supports a rotating shaft rotating around an axis the bearing device is provided. The oil bath type bearing device includes a plurality of bearing pads which are arranged at intervals in a circumferential direction along an outer peripheral surface of the rotating shaft, an annular carrier ring which supports the plurality of bearing pads from an outer peripheral side and in which an oil supply hole through which a lubricant is supplied is formed, and a casing which covers the carrier ring from the outer peripheral side and holds the lubricant between the rotating shaft and the casing. The oil supply hole penetrate the carrier ring from the outer peripheral side to an inner peripheral side and extends toward a rear side in a rotational direction of the rotating shaft as the oil supply hole goes radially inward with respect to the axis.

摘要： A bearing device includes a plurality of bearing pads tiltably supporting a rotation shaft which rotates about an axial line, from the outer circumferential side of the rotation shaft, the bearing pads being spaced apart along the circumferential direction; and an oil supply part that supplies oil between the outer circumferential surface of the rotation shaft and pad surfaces of the bearing pads which face the rotation shaft. The plurality of bearing pads include a first bearing pad that supports the rotation shaft directly below the axial line, and a pair of second bearing pads which sandwich the first bearing pad from the rotation direction. Among the first bearing pad and the second bearing pads, a groove is formed only on the pad surfaces of the second bearing pads so as to extend in the rotation direction.
