In order to solve the problem of Edge Effect and increase the load capacity, the effect of axial material properties on the maximum equivalent stress and the maximum contact stress is studied for cylindrical roller bearings made of functionally gradient materials,with the help of finite element analysis.

This paper presents the dynamic stiffness model of cylindrical roller bearings according to the Lagrange theorem considering both the Hertz elastic deformations and the elastohydrodynamic lubrications,and the model is verified by experiments.

Based on theory of modern elastohydrodynamic lubrication and elasticity,thermal elastohydrodynamic lubrication and stress analysis model of isothermal steady-state,non-isothermal transient,roughness of surface on cylindrical roller bearings was established,and this model was solved by means of numerical analysis.
