Lubricated loaded tooth contact analysis for spur gear pair
International Journal of Powertrains, 2019 Gears are key components to the operation of many machines and mechanisms. However, their presence often affects system efficiency and can lead to noise, vibration and harshness (NVH) issues. Therefore, improved efficiency and NVH refinement are the major drivers in the development of gearing systems.
