Abstract

The invention discloses an intelligent bearing with a state monitoring function. The intelligent bearing comprises an outer ring, an inner ring, a rolling body and a retainer. The intelligent bearing with the state monitoring function is characterized by further comprising a bearing monitoring module and a power supply unit. The bearing monitoring module comprises a data processing unit, a signal transmission unit, a storage unit and a composite sensor unit. The data processing unit, the signal transmission unit and the storage unit are integrated on an integrated circuit board, and the integrated circuit board is arranged in an integrated circuit board mounting groove in the outer wall of the outer ring. The composite sensor unit is arranged on the outer ring and is connected with the data processing unit. And the signal transmission unit and the storage unit are respectively connected with the data processing unit. Due to the bearing monitoring module, the bearing monitoring module is integrated on the integrated circuit board, and the integrated circuit board is arranged in the integrated circuit board mounting groove in the outer wall of the outer ring, so that the device is simple in structure and can monitor the bearing in real time.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to an intelligent bearing with a state monitoring function. Background technique [0002] Bearings are important components of railway operating vehicles. During long-term high-speed and heavy-load operation, in order to ensure operational safety, it is very useful to install sensor components on the basis of existing bearing technology to realize real-time monitoring of bearing operating status. necessary. [0003] DE 10 2009 021 469 A1 shows a sensor bearing unit comprising a rolling bearing having a sensor housing arranged on a bearing ring with an integrated sensor device for detecting the operating state of the bearing. The sensor housing is designed as an adapter ring which bears against the free circumferential surface or end surface of the bearing ring. The sensor device can have, for example, sensors for force measurement which are arranged on the inside of legs of the a...
