Abstract
Due to tooth surface deviations, various kinds of vibration occur depending on mutual geometry of mating gear. From the aspect of ensuring the vibrational behavior, however, it is essential to distinguish individual vibration cause from another, or tooth surface deviations which are the origin of the vibration. Especially, for frequencies other than mesh components, it is quite difficult to predict its existence. This paper proposes a technique to identify the vibrational characteristics inherent to each gear, driving and driven, from acceleration measurement by using a synchronous averaging triggered with once per revolution signal of individual shaft. The test was done using several gears at driving shaft, those are finished by different methods such as indexed generation, continuous generation, etc. The result suggest the measurement is applicable to gear surface inspection.
