<p>PROBLEM TO BE SOLVED: To provide a bearing rotation state measuring monitoring device which can be reduced in size and weight, and can accurately measure and monitor a rotation state of a bearing which rotates at a high speed (for example, a temperature, strain and vibration of the bearing, the number of revolutions of a rolling body or the like).SOLUTION: A bearing rotation state monitoring device comprises: an outer ring; an inner ring; and a plurality of rolling bodies relatively rotating between the outer ring and the inner ring, and monitors a rotation state of the rolling bearing which rotatably supports a rotating shaft. A flange is arranged at the outer ring or the inner ring, a hole is formed in a region opposing the rolling bodies of the flange in a bearing axial direction, and a measuring sensor composed of a strain gauge is embedded in the hole. By this constitution, there can be obtained an effect that the bearing rotation state can be accurately monitored without being influenced by a bearing external atmosphere or the like.</p> |
