<p><P>PROBLEM TO BE SOLVED: To provide a rolling bearing device equipped with a sensor, by which the occurrence of crosstalk in computation is prevented to improve accuracy in computing. <P>SOLUTION: A rolling bearing device equipped with a sensor is provided comprising a cylindrical fixed orbital ring fixed to car body side; a rotation orbital ring rotatably inserted into the inside of the fixed orbital ring and having a wheel-mounting part; and a rolling motion object provided in double rows capable of rolling between the orbital rings, and which is equipped with a sensor device for detecting a gap relative to a peripheral faces of the rotation orbital ring. The sensor device is composed of a first sensor component comprising a plurality of displacement sensors, provided along a circumferential direction and a second sensor component spaced from the first sensor component in an axial direction and comprising a plurality of displacement sensors provided along the circumferential direction. The sensor device is connected with a controlling device having a function of calculating momentum load which interacts on wheels, based on the detected value in the displacement sensor. The controlling device outputs differential output between the output in the displacement sensor of the first sensor component and the output, in the displacement sensor of the second sensor component. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
