- Due to the phase modulation is more sensible to early local gear faults than the amplitude modulation. This paper proposed a new method using phase demodulation based on resonance band for early detection of gear tooth cracking fault. The proposed scheme based on the fact that gear tooth crack can excite impacts which will stimulate the structural/transducer resonances when the cracked tooth is engaged. In this scheme, the synchronous averaging methods are used to eliminate the regular signal first. Then, frequency shift method is used to pick out the phase modulation harmonics in resonant band. At last, the features of gear fault can be indicated by demodulation the phase modulation harmonics. Simulation studies indicated that this method is an effective tool for early detection of local gear faults.
