Abstract
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.
