Gearbox is one of the most widely used transmission systems in the world. However, due to high service load, harsh operating conditions or fatigue, faults may develop in gears. Vibration health monitoring is a non-destructive technique which can be applied to detect faults propagating in gear teeth. The main objective of the work is to detect the Incipient faults in the spur gear. The spur gear is induced with the defects using the Electrical Discharge Machine and damaged gear is installed in the gearbox and signals are collected. The fault symptoms are investigated by comparing the signals from the healthy gearbox with those from the gearbox with a damaged gear. For different defects the vibrations were captured using the Piezo-electric accelerometer and analysed using the MATLAB. The experimental tests have shown that the tooth surface roughness changes and contact length variations will generate impulse vibrations and friction force changes with considerable amplitudes. By the results of this work the problem in the unknown gear can be identified. This method of incipient fault detection is very easy to implement and detect the faults which reduces the time required in disassembly of breakdown machines. The results indicate that the Vibration amplitude intensifies with increase in fault percentage which enables us to identify the damage and replace the gears before breakdown.
