Static Structural and Thermal Analysis of Single Row Deep Groove Ball Bearing

Abstract

Every mechanical system demands relative motion between different machine components. Due to wear and friction, relative motions cause loss of power and degradation of contacting surface. Bearings are machine parts that allow relative motion between two components as well as load transmission from one to another with the minimum amount of friction. Heat production in bearings is represented by transmission power losses. The advent of dilatation has a negative impact on the geometrical features of the bearings due to the rise in temperature caused by heat generation. Contact is a nonlinear complicated event that involves not just state changes but also electricity and heat. This work attempts to present a comparative study of deep groove ball bearing using FEA in Static and Transient Thermal analysis and analytical for a bearing system. In this work, efforts have been made for designing, Static and thermal analysis using ANSYS 18. The first analysis is performed on the SKF 6016 ball bearing in a static structure without the presence of thermal properties. Structural performance of the bearing model such as total deformation, von-mises stress, and life of the bearing is predicted. Next, thermal analysis is performed on the same model with the inclusion of internal heat generation elements and convection. The prediction results of temperature distribution and heat flux are presented. Also, the simulation results discovered that the computational values were reliable with theoretical values. The software tools CATIA and ANSYS Workbench have been employed for modeling and analysis.
