The fundamental reason of noise in gear system is transmission error due to deflection of gear teeth. The vibration from transmission error moves to shaft and bearing. This vibration generates bearing force which exite gear box and finally radiate as noise outside. Therefore, studying transmission error is the most important to predict which is the fundamental reason of gear noise. In this paper, transmission error due to teeth deflection was predicted and shaft torsion was not considered in order to find only teeth deflection. For this reason, shaft was modeled as rigid, and only gear pair was modeled as flexible body. transmission error was predicted by Abaqus, FEA program, and this was compared for Spur and Helical type.
