The diagnosis of gearbox faults based on the Fourier analysis of the vibration signal
produced from a gear reductor system has proved its limitations in terms of spectral
resolution. In this paper, we propose a method for the fault diagnosis of a gear reductor
made of two toothed wheels operating at constant conditions. This technique is based on
Prony method. The good performances of the proposed method relatively to the
synchronous cepstral technique are demonstrated on the basis of experimental data of the …
