Gear drive is one of the most important components in mechanical power transmission systems. Gears in gearbox generally fail when the working contact stress exceeds the contact fatigue limit. In the scope of this paper, the researcher studies gear design methods based on ISO 6336 and draws a comparison with AGMA 9001. In addition, this paper also presents the optimal gear design results with 3D gear models designed in CAD software, then imported into CAE software for topology and shape optimization. More specifically, the amount of material that can be removed from the gear body without affecting the properties of the gear mesh is considered and calculated. Consequently, the aim of this research is to reduce the weight of the gears and choose the optimal parameters of gear pair by contact stress.
