This paper deals with how one can estimate the vibrational behavior of gears enclosed in a gear case by measuring the exterior vibration, i.e., the acceleration of the pedestal, through experimental investigation. In order to compare the vibration of gears with the vibration of a pedestal, accelerations of all principal directions on both gears and pedestals were measured simultaneously. It has been found that the accelerations of pedestals are well correlated to the ones of gears, especially to the rotational one. That is, the transfer function between the acceleration of the gear and the acceleration of the pedestal is necessary for the estimation. It proved that the transfer function obtained through the impact excitation while the gear unit endures a static torque without rotation is applicable to the dynamic estimation of gear vibration.
