Contact problem is one of the most basic problems in the analysis of roller bearings, and the analysis and computation of contact stress and contact deformation are of great importance in roller bearing design. To solve the contact problems of roller bearing, we could use the Traditional method-- Hertz theory, the traditional method to solve the contact problems of roller bearings, is limited in the precision and unable to show the distribution characteristic of stress in contact area.In this paper, we use Finite Element Analysis software ANSYS to do research on contact problem of tapered roller bearing 3811/750/HC, and by means of comparison with the results gained by the Hertz theory we prove the feasibility of roller bearing contact problem by Finite Element Method. Hence, a more efficient method of improving the service life of rollers is got.

This paper presents a novel five degrees-of-freedom model for the static analysis of linear roller bearings subjected to external loading. In this study, first, a rigid analytical model was developed to obtain the roller contact loads and displacements of carriage caused by the elastic deformation at the roller–carriage and roller–rail contacts. The non-Hertzian contact loads between the rollers and raceways were utilized to consider the profiled roller and/or profiled guide rail. Next, the structural deformations of the carriage owing to the contact loads were computed using the finite element method. The associated displacements of the carriage top were derived systematically. Then, the total displacements of the carriage top were obtained by summing the displacements estimated from the rigid model and the induced structural displacements obtained by finite element method. The proposed model was validated by comparing the calculated displacements of the carriage with those from a commercial program under various loading conditions. Further investigation regarding the effect of preload on displacements of the linear roller bearing was conducted. The simulation results showed the dependence of carriage rigidity and internal load distribution on the linear roller bearing characteristics.

The different designs of rollers with varied convexity give different stress distribution and elastic deformation. It is directly related to the load capability and the life length of the roller bearing. With the Finite Element Method(FEM), by analyzing the stress distribution of roller busbar and raceway contact area in the design of different rollers with varied convexity of tapered roller bearing, the paper gets the best solution for the design of convexity of tapered rollers and the cause of roller bearings’ early destroy. The optimal result shows that the service life of this bearing has been improved by 93%. Hence, a more efficient method of improving the service life of rollers is got.
