STUDY ON LOADING ROLLER NUMBER AND MAXIMUM STRESS OF ROLLER BEARING USED IN ROLLING MILL BASED ON FEA

摘要

The support manner of the roller bearings used in rolling mill is different from that of the roller bearings used in conventional condition, so the loading roller number and maximum stress of the bearings can not be calculated accurately through conventional methods.Based on characteristic of the bearings, the model of the bearing is made combining contact mechanics with finite element method.The loading roller number and maximum stress of the bearings are calculated by FEA software.The work of this paper offers a reference to design and manufacture this kind of bearings.
