DEVICE FOR DETECTING AND MONITORING DAMAGE TO ROLLING BEARINGS

摘要

The invention relates to a device for detecting and monitoring damage to races or adjacent regions of bearing rings (1, 2, 3) of anti-friction bearings. The device includes a measuring device, disposed in the anti-friction bearing chamber, having a sensor and structure for supplying sensor measurement data to the outside. The device has an energy source, which is also disposed in the anti-friction roller bearing chamber and which comprises a first coil (16) for the measuring device and a second coil (18) disposed outside the anti-friction bearing chamber and destined for inductive transfer of electrical energy to the first coil (16). The second coil (18) extends only over a part of the bearing circumference and the energy source comprises an energy accumulator (19) connected to the first coil (16).
