| 摘要 |
<p>The present invention concerns a rolling element bearing (1) comprising an inner ring (3), an outer ring (5) and a plurality of rolling elements (7) disposed therebetween on at least one set of opposing raceways (8, 9), the bearing being provided with at least one piezoelectric sensor (10). The at least one piezoelectric sensor is adapted to operate in bending mode, to sense deformation of the bearing due to bending strain, and is capable of sensing dynamic loads and/or vibrations in the bearing.</p> |
