A Gearbox plays a vital role in various industrial processes and because of its criticality, the condition should be monitored closely to prevent any catastrophic failure and prevent huge production losses. Vibration analysis is the most effective predictive maintenance method to detect faults in gearboxes at the early stage itself so that the necessary steps can be taken to prevent failures. Each gear component vibrates differently, creating a distinct pattern. This pattern undergoes a change when there is a fault.

The symptoms differ when the problem is due to damage, imbalance, misalignment etc. The vibration data are collected using a field vibration analyzer. Vibration analysts will be able to diagnose the cause and source of vibration after the detailed spectrum analysis. Conducting vibration analysis in the gearbox helps to predict the faults at the early stage itself thereby helping the maintenance department to schedule the maintenance in advance with a proper plan, resources and tools avoiding the chances of any potential safety concerns.

The Engineer measures the vibration of the machine gearbox using a real time portable vibration analyzer. Each gear component vibrates differently, creating a distinct sound pattern. This pattern undergoes change when there is a fault. As the symptoms are different when the problem is due to damage, imbalance, or misalignment, it helps the engineer to identify the problem. Causes of gear failure could be due to manufacturing or application errors, poor design or maintenance error. Gearbox vibration analysis will be done using vibration analysis methods like frequency or time domain, envelope, order, circular plot, or phase measurement analysis.
