Abstract
Official abstract text for this publication.
An object is to provide a tilting-pad bearing device whereby it is possible to levitate a rotation shaft with a low supply-oil pressure. A tilting-pad bearing device includes a plurality of bearing pads disposed around a rotation shaft so as to support the rotation shaft rotatably, a support member interposed between the plurality of bearing pads and a bearing housing supporting the plurality of bearing pads, the support member supporting each of the plurality of bearing pads pivotably, and an oil-supply mechanism configured to supply a lubricant oil to at least one oil groove formed on a bearing surface of at least one of the plurality of bearing pads. The at least one oil groove is disposed inside and outside a contact area of the bearing surface which is in contact with an outer circumferential surface of the rotation shaft when the rotation shaft is stopped.
