A Calculating Method in Design Flat Air Bearing with Central Feedhole and Pocket

Abstract:

This article presents a calculation method for simple flat air bearing with central feed hole and pocket. A non-dimension relative expression between the load and air lift is obtained by applying some assumptions for the flow, Navier Stokes equations and the equation of equilibrium. The diameter of the feed hole and the central pocket are computed in order to work in optimal regime for the case the working lift is 20µm and the load is 20kG. The results of the theoretical calculation are match with the experimental results and used to manufacture air-bearing slide carrier at Hanoi University of Technology.
