Bearing device, rotating machine, and nozzle

Abstract

This bearing device has: a bearing pad (50) supporting an outer circumferential surface of a rotation shaft rotatably around the axis of the rotation shaft; a nozzle (80) that is disposed on the upstream side of the bearing pad (50) in a rotational direction (T) of the rotation shaft, and has a supply hole (85) for supplying lubrication oil to the outer circumferential surface of the rotation shaft; a pair of side plates (60) disposed on both sides of the nozzle (80) with respect to the axial direction and facing the outer circumferential surface of the rotation shaft on the upstream side of the nozzle (80) in the rotational direction (T), at least one of the pair having formed a discharge hole (61) penetrating through the one side plate in the axial direction; and a guide surface (86) which, at a position between the supply hole (85) and the discharge hole (61) in the circumferential direction, faces the upstream side in the rotational direction (T) and extends in the axial direction along the outer circumferential surface of the rotation shaft.
