Bearing temperature monitoring device and bearing device provided with the monitoring device
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.
