METHOD AND SYSTEM FOR AUTOMATICALLY DETECTING DEFECTS ON A ROTATING SHAFT

摘要

The invention relates to a method and a system for automatically detecting defects on a rotating shaft. The invention comprises the following steps: acquiring a vibratory-type signal from the rotating shaft by means of at least one sensor; processing the signal acquired by the sensor by means of a processor, in the time domain and in the frequency domain, obtaining energy measurements of the acquired signal as a result of said processing; comparing the energy measurements with previously established energy norms, in the processor; and finally, determining whether there are any defects on the rotating shaft on the basis of the comparison between the energy measurements and the previously established norms.
