Abstract:
1. A journal bearing comprising: a bearing platform; a cylindrical bearing housing supported by the bearing platform via a plurality of load supporting members provided between the bearing platform and the bearing housing; a plurality of pads located inside the bearing housing swingable so that a journal of a rotation shaft is supported by the plurality of pads and is capable of being self-aligning; and an oil supply mechanism for supplying lubrication oil to bearing surfaces of the plurality of pads, the oil supply mechanism being provided with an oil supply nozzle having a plurality of nozzle holes, wherein a connecting member is provided between the bearing platform and the bearing housing at a position circumferentially apart from one of the plurality of load supporting members, the connecting member having an oil supply hole to communicate an oil supply passage in the bearing platform, which is an upstream oil passage, with an oil supply passage in the bearing housing, which is a downstream oil passage, so that lubrication oil is supplied from the bearing platform to the bearing surfaces of the plurality of pads, and wherein the connecting member is mounted to the position so as to carry a part of a bearing load exerted from the bearing housing, the part of the bearing load carried by the connecting member being smaller than a bearing load carried by one of the plurality of load supporting members.
