An Analytical Study of Contact Stress and Contact Zone Analysis of Cylindrical (Roller) & Spherical (Ball) Bearings in Epicycloid Condition

This paper reports Contact Stress and Contact Zone Analysis of cylindrical (Roller) & Spherical (Ball) Bearings using M. F. Spotts Analytical Equation for epicycloid condition. The different combinations of ratios of its outer radius and inner radiusi.e. (R2, R1) and the elasticity of the material E1, E2 have been considered to investigate the compressive stresses (P0), and the contact zone (a) on the surfaces of the ball & Roller bearing i.e. Analytical method is applied for the analysis of both spherical and cylindrical type of Ball Bearing Cavity. The results are compared between both type of bearings and final interpretation has been made.
