Fault Analysis Of Two Stage Gearbox Using Acoustic Emission Signal: Effect Of Spalling

Fault detection and diagnosis of gear transmission systems have attracted considerable attention in recent years, due to the need to decrease the downtime on production machinery and to reduce the extent of the secondary damage caused by failures. This paper deals with fault diagnosis of a two stage spur gearbox having pitting defect in driver gear using Wavelet analysis through MATLAB software. For this an experimental setup is fabricated. The Acoustic signals are captured from the experiments and the burst in the Acoustic signal is focused in the analysis and the energy dissipation of the faulty gear is found out.
