BEARING SYSTEM AND CAGE FOR BEARING

摘要

A bearing system and a cage for a bearing are provided. The bearing system includes a bearing, the bearing including: an outer race; an inner race; a roller which is disposed between the outer race and the inner race in a radial direction of the bearing; and a cage which is also disposed between the outer race and the inner race in the radial direction of the bearing and used for keeping the roller. The bearing system further includes a condition monitoring system, the condition monitoring system including: an RFID chip which is fixed to the cage; a printed circuit wire with which the RFID chip is electrically connected, and which is disposed along a circumferential body of the cage and remains conductive so long as a portion of the cage covered by the printed circuit wire is kept intact; and an RFID reader which can communicate with the RFID chip through a radio frequency signal to monitor a condition of the cage. The technical solution of the invention can monitor the condition of the bearing cage more effectively and reliably.
