Power Losses of Spiral Bevel Gears: An Analysis Based on Computational Fluid Dynamics

Energy efficiency is among the predominant aspects in mechanical design. Geared transmissions are widespread several industrial applications and efficiency's improvements translate into various benefits, e.g., reduction of pollutants' emissions, better system's reliability due to lower operating temperatures, higher power density. The possibility compare different solutions preliminary stages design phase plays a determinant role achievements these targets. In particular, Computational Fluid Dynamics (CFD) can be adopted analyze problem interest overcoming limitations analytical equations. On other side, application numerical models gears, which topology domain changes during operation, represents challenging task tailored mesh handling algorithms must implemented. current paper, losses spiral bevel gear were examined numerically with an opensource tool. predictions compared experimental data. approach shows good computational effort making it useful for parametrical studies and, therefore, suggests being effective tool analysis gearboxes' lubrication.
