Online condition monitoring of mechanical systems is gaining importance due to easy detection of root cause of failures. Vibration measurement is a vital tool of online condition monitoring. The present paper describes the experimental observations on pair of spur gears obtained using accelerometer. A test rig has been designed and developed to obtain realistic (in-situ) conditions for spur gear. The developed test setup can be used to vary the speed from 600 rpm to 24,000 rpm. Accelerometer is used to measure the vibration of the system and the acquired signals are analyzed to predict the system performance. To confirm the conclusions from the vibration results, inspection using optical microscope on the gear surface were carried out before and after performing experiments.
