Abstract

A method for measuring the bearing clearance. A bearing comprises an outer ring (2), an inner ring (3), and a rolling body (4). The rolling body (4) is placed between the outer ring (2) and the inner ring (3); a stress sensor (5) is placed on the surface of the outer ring (2) and/or the inner ring (3) opposite to the rolling body (4). The method comprises the following steps: first, measuring the stress distribution of the outer ring (2) and/or the inner ring (3) by means of the stress sensor (5); and then calculating the size of the bearing clearance according to the measured stress distribution, further determining the operating state of the bearing on the basis of the calculated size of the bearing clearance, and controlling a hydraulic device to make a real-time adjustment so that the bearing is in the best state for prolonging the service life of the bearing. Also provided is a bearing device (1) capable of adjusting the bearing clearance.
