PROBLEM TO BE SOLVED: To obtain a novel structure which can measure a displacement amount of a bearing ring of a rolling bearing based on a load when the load is applied to the rolling bearing.SOLUTION: A lever member 27 constituting a sensor device 9 is fixed to an outer ring 3a so as to be oscillatory with an oscillation support part 33 as a center. A sensor main body 30 is made to oppose a measured part 32 of the lever member 27, and an action part 34 of the lever member 27 is pressed against a partial conical face 16 of an inner ring 5a by a plate spring 28. When a radial load is applied to the inner ring 5a, and the inner ring is displaced in a radial direction, the action part 34 of the lever member 27 is pressed against the partial conical face 16 of the inner ring 5a, and the lever member 27 is oscillated. A displacement amount of the measured part 32 accompanied by the oscillation is measured by the sensor main body 30.SELECTED DRAWING: Figure 6 |
