A finite element analysis of an elastic contact between a layered cylindrical hollow roller and flat contact

Purpose - The purpose of this paper is to present a finite element analysis (FEA) which shows the comparison between a layered cylindrical hollow roller bearing and hollow roller bearing. Design/methodology/approach - In this work, FEA is carried out to solve the elastic contact between a layered cylindrical hollow roller and flat contact for different hollowness percentages ranging from 10 to 80 per cent. Graphical solution is developed to determine the optimum hollowness of a cylindrical roller bearing for which induced bending stress should be within endurance limit of the material. Findings - Different parameters such as von Mises stress, contact pressure, contact width and deformation are shown here. Originality/value - The value of this research work is the calculation of contact width and other parameters using FEA for layered cylindrical hollow roller bearing.
