To　improve　the　comprehensive　diagnosis　ability　and　extract　signal　feature　of　the　gear-box　typical　fault　in　the　high　speed　wire　rolling　mill,　this　paper　puts　forward　a　comprehensive　traditional-new　(CTN)　diagnosis　method　in　which　time　domain　wave　analysis,　frequency　analysis,　time-domain　trend　analysis　and　characteristic　frequency　amplitude　trend　analysis　are　used　to　judge　the　status　of　the　machine　and　fault　parts　qualitatively,　and　then　precision　diagnosis　of　wavelet　packet　decomposition　and　reconstruction　based　on　the　multi-resolution　analysis　is　used.　The　research　results　arrive　at　the　exact　judgment　of　the　fault　quality　and　fault　position　quantitatively,　which　indicates　the　validity　and　the　practicability　of　the　proposed　method.
