Abstract
Method for acquiring data for detecting damage to a bearing, comprising the following steps: obtaining a vibration signal from the bearing over a period of time, determining spectrograms of said vibration signal at various instants of the period of time, detecting the peaks on each spectrogram, from among the detected peaks, retaining the peaks which, in spectrograms corresponding to successive instants and transformed through synchronous resampling at a rotational speed of the bearing, would be present at the same frequency, with a predetermined tolerance, identifying spectral lines corresponding to the retained peaks, and storing information representative of said spectral lines in a record able to be used by a unit for detecting damage to the bearing.
