Damages detecting and monitoring device for e.g. tracks of crane's ball bearing ring, has energy source with rail extending over bearing periphery part and storage to store energy, and transmitting device with contact assigned to rail

摘要

The device has an electrical measuring device arranged in a rolling body area (3), with a sensor to release measuring signals and a delivering device to deliver measuring data. An energy source (15) arranged in the area delivers an electrical energy required for the measuring device. A transmitting device arranged outside the area transmits the energy. The source has a contact rail (20) extending over a part of a bearing periphery, and an energy storage (21) is connected with the energy source to store the energy, while the transmitting device has a sliding contact (22) assigned to the rail.
