Abstract:

With wide application of worm-gear reducer, the fault type is complicated and concealed, which not only bring huge economic losses, and even a threat to the safety of workers. in order to solve the problems, this paper put forward a fault diagnosis system of worm-gear reducer based on wavelet analysis, which base on real work situation, develop fault diagnosis system by adopting LabVIEW language, achieve vibration signal for acquisition and display, wavelet analysis and off-line fault diagnosis, experimental results show that the fault diagnosis system of worm-gear reducer based on wavelet analysis can better realize the worm-gear reducer fault diagnosis, so can be used in the field of technology research and safety using.

Key words: fault diagnosis, wavelet analysis, vibration signal, LabVIEW
