The Design of Partly Grooved, Externally Pressurized Journal Bearings

Abstract

The equation for the pressure buildup in these bearings is subjected to a first-order perturbation with respect to parallel as well as skewed displacements of the center lines of journal and bearing. Fluid film forces and their points of application can thus be found. Several configurations of these bearings are discussed. One configuration acts as a simple support, and two others act as a clamped support to the rotatable journal. Promising applications in machines are also discussed.
