• Condition monitoring of plant, machinery, equipment and structures ensures reduction in costly unscheduled machine downtime. In this paper, vibration signature and acoustic emission (AE) are demonstrated to diagnose the common faults arising in a gearbox. The vibration and acoustic signature have four characteristic frequencies corresponding to input shaft, intermediate shaft and gear tooth meshing frequency. Peculiar deviation in normal amplitude spectrum, caused by common faults such as rotary imbalance, looseness, shaft misalignment and damaged tooth of gear or pinion, is identified to diagnose the faults. By periodic in-process monitoring of the acoustic signal and frequency spectrum, impending fault can be diagnosed and the root cause of the fault can be traced using the diagnostic chart. Vibration-based condition monitoring is more effective predictive maintenance tool, though equipment cost required for vibration is high as compared to other condition monitoring techniques. Thus, breakdown can be avoided and maintenance can be scheduled and carried out with clinical precision with minimal downtime, thereby avoiding loss in production and product quality.
