Abstract：Because of Teager energy operator’s insufficient in demodulating rolling bearing’s incipient weak fault feature. A diagnosis method combined maximum correlated kurtosis deconvolution(MCKD) and Teager energy operator was proposed. First, the original signal was de-nosed by MCKD arithmetic with the goal of the max kurtosis of its envelope spectrum to detect the periodic impact component. Then the periodic impact component was enhanced and the non impact component was inhibited by using Teager energy operator. At last, the fault type was diagnosed by analyzing the obvious frequency component in the Teager energy spectrum. Analysis results of the rolling bearing’s outer fault and inner fault test signals proved this method could identify the incipient weak fault of rolling bearing effectively.
