Modeling and Structural Analysis of A Ball Bearing

Abstract


The bearings provide relative positioning and rotating freedom while usually transmitting a load between shaft and housing. Ball rolling contact bearing is also call anti-friction ball bearing due to low friction generate between balls, lower and outer races. Ball bearing used for both radial and axial forces. The major issue in ball bearing application is formation of noise while be in working condition. Optimization of contact angle with proper material in ball bearing is helps to reduce the noise.

Angle of contact is defined as the angle between line joining contact points of ball and races. The contact angle of the ball bearing typically varies from 15 degrees and is measured in relative proportion to the line running perpendicular to the bearing axis.This project include about optimization of noise (less stress, deformation and frequency ) in ball bearings using finite element analysis software. Analysis of ball bearing was done in Ansys software. Also different materials are used for optimization of stress, deformations and frequency, best material is suitable to ball bearing. Design of ball bearing passed through NX CAD software.
