Elastic Orifices for Gas Bearings

Abstract

This report describes an examination of the merits of an elastic orfice in externally pressurized gas bearings. The use of an elastic orifice in a test bearing demonstrated a threefold increase in bearing stiffness over a conventional fixed orifice when the two were compared at a common operating point as defined in this report. This increase should be welcomed wherever externally pressurized bearings are used. In addition, increased bearing stiffness may allow the use of these bearings in some applications formerly restricted to pressurized liquid and rolling contact bearings. Information is included to allow construction of working models of these orifices and duplication of experimental results.
