When a gearbox vibrates as a whole, the severity of the vibration can be detected at the outer surface of the gearbox housing. While some vibration is normal, higher levels of vibration can be caused by the wearing or failure of the gearbox components. For this reason, gearboxes often incorporate vibration sensors to detect conditions…
