In this paper the study of dynamic performance analysis of Involute helical gear with defects is presented. Analysis is carried out to solve noise and vibration problems. It improves reliability and safety of the gear. This paper proposes study of the common failures of gearbox and vibration analysis related to gearbox defects and its diagnosis, distinct vibration pattern related to gearing defect and noise level of gearbox and its pattern due to defects in gear during its working. For this, we designed and developed small gearbox and experimental setup for study of vibration analysis then analysed the vibration signature of a healthy gearbox. Created different gear defects (Defects selected for this is pitting, tooth breakage in steps from 25% of one tooth breakage up to complete one tooth breakage and scoring.) on gear that normally occurs in a gearbox during power transmission and analysed each defect by vibration signal analysis, compared a faulty vibration signature with healthy gearbox vibration signature and concluded the distinct vibration signature of the defect.
