| Abstract: | In this paper,wavelet transform is used to decompose the vibration acceleration signals of ball bearing faults to different scales,and the wavelet coefficients involving fault feature frequency is demodulated by Hirbert transformer.Afterword,the frequency analysis of the signals demodulated has been done to obtain the fault characteristic information of ball bearings. Case analysis shows that the use of wavelet transform fault diagnosis of roller bearing inner ring has good results. |
