NONCONVENTIONAL METHOD OF SPHERICAL ROLLER BEARING DESIGN, USING FEA

Abstract

This paperwork presents the analysis of roller bearing design, in order to optimize the classical process, using the finite element method or Finite Element Analysis (FEA). First of all, it was studied theoretically modelling/simulation with finite element to understand in the best way how this works and how to obtain the best results of the study. Then it was brought a general presentation of spherical roller bearing and in the very next phase some types of spherical roller bearings were designed using the 3D software Creo Parametric, to import the geometry created in the finite element software Ansys. Next step was to initiate a study of static load conditions of spherical roller bearings and the variation of equivalent elastic strain and elastic stress, using Ansys Workbench and Ansys Mechanical Design. In the last part of the paper, using the results obtained with Ansys and the multiple-criteria decision, it was elaborated a new design version of spherical roller bearing.
