THE CURRENT STATE OF THE ART OF FLUID BEARINGS WITH DISCRETE SLOT INLETS

This paper is intended to present the current state of the art of a novel type of externally pressurized bearing, in which the supporting fluid is fed to the bearing gap through strategically positioned discrete slots, as opposed to orifices or capillaries. The discrete slot formation lends itself to a wide variety of bearing configurations and shows to advantage in bearings of extremely low L/D ratios and also in small sizes. A brief assessment of performance is presented together with some current applications. Development of this bearing design is less than a decade old and much work is still to be undertaken. In view, however, of current widespread interest in the U.K. by Government Departments, research groups, and commercial organizations, this paper attempts to describe development to date. The concept of the bearing was conceived after fairly comprehensive study of the problems associated with the orifice design.
