Title:
BEARING COMPONENT WITH SENSOR, AND BEARING CLEARANCE MONITORING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/215256
Kind Code:
A1
Abstract:
A bearing component with a sensor, comprising an axle box base (21), an axle box end cover (22), a bearing, and a sensor component. The bearing comprises a movable ring capable of rotating or creeping relative to the axle box base (21). The sensor component comprises the sensor, a sensor antenna, and a transceiving antenna (T14). The sensor is fixed on an end portion of the movable ring close to the axle box end cover (22) in an axial direction (A), is electrically connected to the sensor antenna, and is capable of measuring the change in the state of the movable ring, and transferring a state signal obtained by measurement to the sensor antenna. The sensor antenna can wirelessly transmit the state signal to the surrounding. The transceiving antenna (T14) is fixed on an end surface of the axle box end cover (22) facing the bearing, and can receive the state signal transmitted by the sensor antenna. According to the bearing component, the working condition of the movable ring of the bearing can be measured accurately and in real time. The present invention also relates to a bearing clearance monitoring system.
