In the paper, a new fault diagnosis method for gearbox combining with the kurtosis of fast spectrum and 1.5 dimension spectrum is proposed aiming at the problem that the initial failure of gearbox is difficult to be recognized. Firstly, the maximum frequency band of kurtosis for original signal is filtrated with kurtosis of fast spectrum, and then the filtrated frequency band is analyzed with 1.5 dimension spectrum. Finally, the positions of faults for gearbox are determined by analyzing prominent components in the spectrogram so as to take precautions in advance. The method is with the analysis validation by project cases, it is fully proved that the fault information could be effectively extracted with this method, which plays a certain guiding role in engineering applications.
