Title: JOURNAL BEARING AND ROTARY MACHINE
Abstract:
A journal bearing that comprises: a carrier ring; a plurality of bearing pads that are provided on the inner circumferential side of a lower half region of the carrier ring and that are configured to support a rotor shaft from below; and a pair of side plates that are provided on both sides of the plurality of bearing pads with respect to the axial direction of the rotor shaft. Each of the side plates includes: a first region that includes an upstream-side circumferential-direction area of a first bearing pad that, of the plurality of bearing pads, is located furthest upstream; and a second region that is located on the upstream side of the first region and that has a larger gap between an inner circumferential surface of the side plate and an outer circumferential surface of the rotor shaft than the first region.
