Influences of Coefficient of Frictions on The Contact Behavior for Ball Bearings
The study presents the wear analysis assessment of a ball bearing using the finite element method. Ball bearings are used in various sectors, such as in the automotive, turbine and aircraft engine industries, to reduce rotational friction and support radial loads. However, ball bearings often experience failure due to wear as a result of contact pressure. Therefore, the main objective of this study was to examine the stress distribution for a wear analysis of a ball bearing. A 2-dimensional model with coefficients of friction of 0, 0.05, and 0.30 was used for the sliding wear analysis. The maximum von Mises stress position was closer to the surface of the inner ring when the coefficient of friction was high. Damage to the material occurred at the sub-surface in the inner ring when the coefficient of friction was 0.05, while spalling of the material occurred when the coefficient of friction was 0.30
