Method and device for detecting electrical current pulses occurring in a rolling bearing as a result of static charging of rotating machine/system parts

A device for detecting characteristic electrical current pulses flowing through a rolling bearing or sliding bearing as a result of static charging of rotating machine or system parts, the device comprising:

• a receiving unit configured to receive electromagnetic radio waves emitted in a frequency range above 50 MHz as a result of the characteristic electrical current pulses;
• a signal processing unit configured to process a received signal by signal processing in order to extract current pulse events contained therein, including filtering;
• and
• an analysis unit configured to analyze a temporal progression of the current pulse events for condition monitoring of the rolling bearing or sliding bearing.

A device for detecting characteristic electrical current pulses flowing through a rolling bearing or sliding bearing as a result of static charging of rotating machine or system parts, the device comprising:

• a receiver configured to receive electromagnetic radio waves emitted due to rotation of the rotating machine or system parts via the rolling or sliding bearing in a frequency range above 50 MHz as a result of the characteristic electrical current pulses;
• a signal processer configured to process a received signal from the receiver by signal processing in order to extract current pulse events contained therein, including filtering;
• and
• a signal analyzer configured to analyze a temporal progression of the current pulse events for condition monitoring of the rolling bearing or sliding bearing.
