Abstract
The bearing device has a bearing housing which is supported by a bearing base mounted on a body of a rotary machine equipped with a rotating shaft and through which the rotating shaft penetrates at the center and a plurality of pads which are arranged inside the bearing housing so as to circumferentially surround the rotating shaft and rotatably support the rotating shaft. A contact surface between an outer circumference of the bearing housing and an inner circumference of the bearing base extends along the axial direction of the rotating shaft and forms a convex curved surface protruding outward, and the bearing housing is slidably supported by the bearing base via the contact surface of the convex curved surface. At least either the inner circumference of the bearing housing or the outer circumference of the pad forms a curved surface extending along the axial direction, and a distance between the inner circumference of the bearing housing and the outer circumference of the pad gradually increases from the center towards the ends along the axial direction.
