Computer Aided Rating of Large Diameter Rotation Bearings

Abstract

An interactive computer aided analysis program is developed to assist in the rating of large diameter, special configuration, case hardened, four point contact ball bearings. The rating equations are developed from the results of two models. The finite element method is used for one model. The second model will consist of equations that are developed assuming the bearing race remain rigid when loaded. With dimensional parameters from several bearings, moment, radial, and thrust loads will be applied to both models. As needed, relationships between the two models will be obtained for the rating equations.
