Analysis of Whole Contact Stresses of Tapered Roller Bearings under Radial Forces，Axial Forces and Moment Loads

Abstract

Abstract: Firstly, the equilibrium equations of a single tapered roller bearing under radial, axial and bending moment loads were derived, according to the conditions of deformation compatibility and force balance, a mathematical model of the whole contact analyses was established, the whole balance equation of the tapered roller bearings was finally formulated to solve a set of nonlinear equations. Then the numerical solution procedure was programmed by MATLAB, through the iterative method, the solutions to the whole balance equation were obtained. Finally, an example was given to verify the analyses.

Key words: tapered roller bearing, contact stress, numerical solution； balance equation
