Abstract
This study performs a behavioural numerical analysis of stress, strain and deformation of chromium (UN367) and tungsten (EN1088) alloy materials for rolling bearing element. Radial internal clearance within the rings and rolling element of a bearing is a critical factor in deciding the life span of rolling element bearings. Chromium alloys are mostly used for making bearings to resist corrosion and compatible with lubricants. Tungsten alloys are good materials which have properties slightly stronger than chromium. Solidworks 2019 was used in designing the model bearings and exported to Ansys Workbench 2019 for simulation numerical analysis of the two materials. Results show that the stress value in UN367 with minimum of 0.040189 to maximum value of 3.866e +14 bearing was higher than stress in EN1088 with minimum of 0.3668 to maximum 1.0912e+13 in the bearing. Numerical result also indicated that UN367 (chromium) deformed more than EN1088 (tungsten). EN1088 resisted deformation better than UN367. The minimum equivalent strain values for EN1088 and UN367 were discovered to be 3.8546e-12 and 5.9065e-12; maximum values of 1078.5 and 1089.2 respectively. Simulation results also show that UN367 was found to have stretched more than EN1088. It is therefore recommended that the EN1088 should be used for manufacturing of roller bearing.
