Crowned Profile Design of Roller Bearings Used in Rolling Mill Based on Three Dimension FEA

Abstract

Aiming at the characteristic of bearings supported in rolling mill and combining contact mechanics and finite element method, the edge effects of the cylindrical roller bearings used in the rolling mill are analyzed based on FEA for the Roller system of Rolling Mill and FEA of the bearing whole. According to the results of three dimensions FEA on the edge effects, different modification curves are taken to design crowned profiles of the cylindrical roller bearings. And comparison between the effects of the different modification curves is done through the simulation of 3D FEA, so the guides are offered to optimize the cylindrical roller bearings used in the rolling mill.
