Abstract
Tooth surface form inspection is generally performed for quality check of gears. But inspection of single gear can't estimate gear pair's characteristic, effect of alignment error, elastic deformation of shafts and gearbox. Therefore, inspection method not for single gear but for gear unit is desirable. Authors had proposed the method that estimate frequency response function(FRF) of a gear system with vibration measurement. It enables to obtain mesh excitation force and to estimate surface form characteristics. In the proposed study, vibration signal is measured on gear body. But mounting vibration transducers on rotating gear costs expensive for practical use on quality check, diagnosis, etc. In this study, we discuss about FRF estimation with vibration measurement on pedestal.
