A planetary gear train is provided with: a planetary gear; a planetary pin for supporting the planetary gear; a carrier for supporting the planetary pin; and a housing for accommodating at least a portion of the carrier, the planetary gear and the planetary pin. The planetary gear is rotatable with respect to the planetary pin by a bearing. An oiling flow path for supplying lubricant oil to the bearing is formed inside the carrier. The carrier receives the lubricant oil into the oiling flow path from an oiling member stationarily fixed to the housing. The inlet for receiving the lubricant oil into the oiling flow path of the carrier from the oiling member is positioned inside the housing.

A bearing temperature monitoring device and bearing device provided with the monitoring device composed so that occurrence of scratch on the rotation shaft supported by the bearing caused by a bearing temperature carrying member integrated in the bearing such that its top end surface faces the rotation shaft, are provided. The bearing device is provided with a bearing temperature detecting device which comprises a bearing temperature carrying member made of material larger in thermal conductivity than the bearing layer and shaped to have a protruded part to be inserted slidably into a through hole in the bearing layer and a base part to be received in a cylindrical space in the back metal, the base part serving to restrict protrusion of the protruded part into the through hole so that the top end surface thereof is level with the sliding surface of the bearing layer, a pushing member attached to the back metal to push the temperature carrying member so that the member move toward the back metal against the pushing force of the pushing member when bearing load exerts on the temperature carrying member, and a temperature sensor for detecting temperature of the temperature carrying member.

A journal bearing includes a bearing platform, a cylindrical bearing housing supported by the bearing platform via a plurality of load supporting members, a plurality of pads located swingable in the bearing housing so that a journal of a rotation shaft is supported by the pads, an oil supply mechanism for supplying oil to the bearing surfaces of the pads, and a connecting member which has an oil hole to communicate an oil supply passage in the bearing platform with an oil supply passage in the bearing housing so that oil is supplied from the bearing platform to the bearing surfaces of the pads. The connecting member carries a part of a bearing load exerted from the bearing housing, and is mounted such that the part of the bearing load carried by the connecting member is smaller than a bearing load carried by one of the load supporting members.
