Abstract
Gear transmission is one of the most important mechanical transmissions. It is widely used because of its high efficiency, compact structure, stable transmission ratio, etc. In general, the failure of gear transmission is mainly due to the failure of tooth. Tooth broken main failure mode of gear tooth is mainly due to the role of the tooth root bending fatigue. So, researching both tooth root bending fatigue strength and tooth surface contact fatigue strength are of great significance for the guarantee of gear life. Basing on romax this paper chooses a gear-bearing-rotor system as the research background to conduct parameter sensitivity analysis of gear contact and simulate the changes of tooth root bending stress and contact lines position in the whole meshing process of gear pair.
