Design and Analysis of Air Bearing using Orifice and Feed Hole Pocket

Nileshkumar T. Raval, Prof. M. Y. Patil

Abstract :

Air beås are extensively used in precision machines and equipment in recent years. Unlike conventional beås, there is no physical contact between the sliding surfaces. The moving surface can glide smoothly on the other surface, minimizing the control effort to achieve high accuracy and precision. Finally, a three–dimensional (3D) model was built for Computational Fluid Dynamics (CFD) analysis to verify the theoretical result. A test set–up was designed to measure and study the performance of different kind of air beås for future air beå development. The stiffness and forces of various geometric designs of aerostatic thrust beås were investigated under different operating conditions. The results also provided helpful design guidelines for gas–beå in high–precision machine applications. When value of pressure increased from 5 bars to 7 bars, forces and stiffness value decreased for geometries.
