On the Design of Combined Hydrostatic and Dynamic Bearings,
Abstract
Hydrodynamic bearings offer lubrication only within a certain range of speeds, typically 15-20 meters per second relative displacement. Hydrostatic bearings provide lubrication at all speeds, but require auxiliary pressure apparatus. In addition, hydrodynamic effects frequently occur in hydrostatic bearings. The parameters of bearings can all be determined if the pressure is known at all points in the gap between the surfaces. A mathematical expression can be formulated for the laminar flow of a viscous fluid, but in the general case it is unsolvable, since the solution is statistically indeterminate. However, by applying both zero and nonzero boundary conditions, it is possible to develop expressions which can yield results. (Author)
