From the structural and assembly characteristics of hypoid gear main reducer assembly

the way to process characteristic parameters of the vibration acceleration single amplitude domain

time domain and frequency domain of the main reducer housing is studied.In the amplitude domain analysis

peak

root-mean-square

shaper factor and kurtosis value are selected as the basis of fault analysis mainly through comparing the characteristics sensitivity of various typical faults.In the time domain analysis

to distinguish bearing and gear fault

the way of combining time domain waveform and time domain average waveform is used.The accuracy of power spectrum analysis is improved by adopting Multi-segment average technique in the frequency domain analysis. The availability of ways to estimate the quality by mixing characteristics parameters is demonstrated by the experiments.
