Abstract

The invention relates to a bearing structure which comprises a bearing main body, a signal processor, a signal emitter and a power supply. The bearing main body comprises a bearing inner ring and a bearing outer ring, and the bearing inner ring and the bearing outer ring are relatively rotatably assembled through a bearing retainer; at least one sensitive coating is formed on at least one part area of at least one side wall of the bearing outer ring; a sensitive groove is formed in the sensitive coating, and the sensitive groove is configured for generating corresponding resistance change with temperature change, and the signal processor is arranged on the bearing outer ring; the signal processor is electrically connected with the sensitive groove, and the signal transmitter is arranged on the bearing outer ring; and the signal transmitter is electrically connected with the signal processor, and the power supply is arranged on the bearing outer ring. According to the bearing structure, the sensitive coating capable of acquiring temperature information in real time is integrated on the outer ring of the bearing, the working state of the bearing structure can be monitored in situ at a short distance, the real measured value of the bearing is acquired, and the loss caused by signal transmission is reduced.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a bearing structure. Background technique [0002] The temperature and strain of the bearing are two important parameters that can reflect the working state of the bearing. Real-time monitoring of the temperature and strain of the bearing is helpful to understand the working state of the bearing, so as to make timely adjustments to avoid unnecessary errors caused by operating errors and overload operation. loss. [0003] Currently commonly used monitoring methods are implanted and plug-in. The internal implant type is to slot, open holes, modify the size, etc. inside the bearing, and implant the monitoring sensor inside the bearing. The disadvantage is that the installation space of the monitoring sensor is limited, and it is easy to affect the bearing force form due to the change of the bearing structure. Affect the life of the bearing, cause problems such as difficult wiring...
