Abstract

Abstract: A method using wavelet packets and signal reconstruction is proposed to extract shock signal from vibration signal of rolling bearing, which is concealed by noises. By analyzing vibration signal of rolling bearing with inner ring pitting, outer ring pitting and normal status, it is confirmed that wavelet transform can be applied in failure diagnosis of rolling bearings successfully.

Key words: Failure diagnosis, Rolling bearing, Signal reconstruction, Wavelet, Wavelet packet
