Wavelet Transform And Envelope Detection For Gear Fault Diagnosis .A Comparative Study

A.boudiaf, Z.Mentouri, S.Ziani, A.boudiaf

Abstract : On-line vibration monitoring of Rotary Machinesis is a fundamental axis of development and industrial research.

Itspurpose is to provide knowledge about the working condition ofmachines at each moment without stopping the production line.This method allows avoiding the production losses related tobreakdowns and reducing overall maintenance costs.Bearing fault diagnosis is important in vibration monitoringof any rotating machine. Early fault detection in machineries cansave millions of dollars in emergency maintenance cost.This paper presents the comparison results of Fault diagnosisTechniques of gear fault using two methods: Envelope Detection(ED) and Wavelet Transform (WT) using Morlet Wavelet thecomparative study is applied to real vibratory signals.

Keywords : Vibration analysis, Fault Diagnosis, Wavelet Transform (WT), Envelope Detection (ED)
