Journal bearing and rotary machine
A journal bearing includes: a carrier ring; a plurality of bearing pads disposed on a radially inner side of a lower half region of the carrier ring and configured to support a rotor shaft from below; a pair of side plates disposed on both sides of the plurality of bearing pads, with respect to an axial direction of the rotor shaft; and a dam disposed on a radially inner side of the carrier ring, in a downstream section of an upper half region of the carrier ring, and configured to suppress a downstream flow of carried-over oil. A gap is provided between inner peripheral surfaces of the respective side plates and an outer peripheral surface of the rotor shaft, for bringing into communication an outside and a bearing interior space surrounded by the pair of side plates.
