<P>PROBLEM TO BE SOLVED: To provide sensors which report conditions such as vibration, etc., of a bearing device to the outside precisely, and the bearing device fitted with the sensors. <P>SOLUTION: This bearing device with sensors is provided with a roller bearing 3 having a plurality of rollers between a stationary side bearing ring and a rotating side bearing ring, and a temperature sensor 30. The device is provided with a control means 35 which estimates an actual temperature of the roller bearings 3 from a temperature detected by the temperature sensor 30 at real time simultaneously, on the basis of the relation between the actual temperature of the roller bearing 3 and the detected temperature by the temperature sensor 30, which are found beforehand. <P>COPYRIGHT: (C)2003,JPO |
