DEVICE FOR OBTAINING OPERATING DATA OF A ROLLING BEARING

摘要

The invention relates to a device for detecting operating data of a rolling bearing (1), said device comprising at least one sensor (4) arranged on a component (3) of the rolling bearing (1), which is fixed in the assembled position in relation to a bearing housing (15) receiving the rolling bearing (1). A transmitter (9) on the sensor side sends radio signals (10) representing operating data to a data receiver (12) arranged on the side of the bearing housing. In order to ensure that the operating data of the rolling bearing is reliably detected independently from the current operating situation of the rolling bearing, the energy feeding device (29) comprises a transmission unit (25) on the side of the bearing housing, which wirelessly supplies a receiving unit (6) on the transmitter side with operating energy (30) used as transmission energy for the transmitter (9) on the sensor side.
