Comparative Analysis of Sn–Pb–Sb Babbitt bearing alloys material with and without copper

The most frequently used bearing is the deep groove ball bearing. It is found in almost all kinds of products in general mechanical engineering. Babbitts, also known as white metals, are either tin or lead-base alloys having excellent embed abilityand conformability characteristics. The Babbitts,are among the most widely used materials for lubricated bearings.The development of new advanced material is an important activity for continues progress in science and technology. Considerable research and development efforts are underway towards the development of tin-based bearing alloys. The effect of Copper in Babbittmaterial is considered as the Bearing Materials for comparative analysis in between the Babbittshaving copper and doesn't. A Numerical analysis has been carried out for constant speed and at different bearingloads. The comparative analysis is based on the parameters like Elastic Strain, Maximum Principal Elastic Strain, Maximum Shear Elastic Strain, Equivalent Stress (MPa), Maximum Principal Stress (MPa), Maximum Shear Stress (MPa), Stress Ratio, Strain Energy (J) and Safety Factor. A structural analysis has been carried out. The design considers for the study of SKF6003 Bearings with the maximum load carrying capacity of 35MPa.As the results it has been find out that the copper mixing of 5% in Babbitt consider for study is profitable for enhancing the material property for the bearing applications.
