Abstract
In order to explore the static contact problem between the rolling element and raceway of the elastic composite cylindrical roller bearing based on the locomotive wheel set, the mechanical analysis of the new type bearing of the locomotive wheel set is carried out by using the numerical simulation method and the theoretical analysis method. The contact stress, contact half width, contact displacement and contact stress of the elastic composite cylindrical roller bearing under the load of locomotive wheel pair are analyzed by finite element method The results show that: the contact displacement and contact half width of the elastic composite cylindrical rolling element applied to locomotive wheel set increase with the increase of filling degree; the contact stress and equivalent stress have minimum values with the increase of filling degree, and the minimum values change regularly. Compared with the solid cylindrical roller bearing, the elastic composite cylindrical roller bearing has obvious advantages in contact stress. Reasonable filling degree can reduce the contact stress and improve the edge effect.
