| Abstract: | An efficient method is
proposed for diagnosis of the rolling bearing's early fault. The fault signal is abstracted and
amplified from the vibration signal of the rolling bearing with high background noise using narrow
band filtration, envelope analysis and wavelet transformation. Several 307 rolling bearings are
considered as examples to illustrate the validity. This method is very suitable for the online
inspection and diagnosis of the rolling bearing. |
