Abstract

The new technique of normalised wavelet spectral cross-covariance (WSC) of complex transient spectral components has been implemented for the first time for condition monitoring of gearboxes. This novel approach overcomes the limitations imposed by previously used techniques based on the higher order spectra. In this paper, the superiority of the new method is discussed. The effectiveness of normalised wavelet spectral cross-covariance gearbox diagnosis has been experimentally revealed. The developed gear tooth local faults have been diagnosed and localized at an early stage of pitting development. The results have been compared with results obtained using the wavelet bicoherence.
