Journal bearing

Abstract

A journal bearing which can be constructed without leading to decrease in rigidity and increase in size, in which lubrication oil can be supplied to the bearing surfaces of the pads with certainty. The journal bearing 10 having a bearing platform 20, a cylindrical bearing housing 30 supported by the bearing platform by the intermediary of a plurality of load supporting members 33, a plurality of pads 40a-40b located swingablly in the bearing housing so that a journal j of a rotation shaft is supported by the pads capable of being self-aligning, and oil supply means for supplying lubrication oil to the bearing surfaces 48 of the pads, is composed such that a connecting member 62 is provided in addition to said load supporting members 33, said connecting member 62 having an oil hole 62a to communicate an oil supply passage 60 in the bearing platform 20 with an oil supply passage consisting of passages 64, 66, and 68 in the bearing housing 30 so that lubrication oil is supplied from the bearing platform 20 to the bearing surfaces 48 of the pads 40a-40b, said connecting member 62 also serving to carry a part of bearing load exerted from the bearing housing 30, and that said connecting member 62 is mounted to said position in such a manner that said part of bearing load carried by the connecting member 62 is smaller than bearing load carried by one of the load supporting members 33.
