摘要：

Application　of　wavelet　packet　transform　to　fault　diagnosis　of　gear　box　is　introduced.　From　wavelet　packet　transform　of　vibration　signal　to　gear　box,　the　fault　information　of　gear　box　bolt　snapped　can　be　effectively　extracted.　According　to　the　fault　mechanism,　vibration　signal　of　rotating　machinery　has　steady　frequency　distribution.　If　every　feature　of　fault　frequency　can　be　extracted,　symptoms　for　fault　diagnosis　can　be　provided.
