Bearings always work under harsh environment, which makes them easily to failure. Fault detection of the bearing is a key issue for maintaining the whole machinery system. In this paper, a novel method is proposed to detect the fault of bearings. Tunable Q-factor wavelet transform (TQWT) is used to decompose the original vibration bearing signal to several levels, the Hilbert envelope analysis method is applied to each wavelet decomposed signal. The fault feature of the bearing can be detected from the envelope spectrum. Both the simulation study and the application demonstrate the effectiveness of the proposed method.
