Inertia Effects in Hydrostatic Thrust Bearings

Journal of Basic Engineering, 1961
This paper includes the predominant inertia terms in an analysis of hydrostatic thrust bearings. The influence of centripetal accelerations on the distribution of pressure is found to be considerable.

Experimental and theoretical study on the dynamic stiffness of circular oil hydrostatic shallow recess thrust bearings [PDF]

Tribology International, 2023
The dynamic stiffness of traditional (deep recess) hydrostatic bearings decreases due to the fluid compressibility between the bearing and a compensation device, e.g., a capillary. Shallow recess bearings, on the other hand, reduce the influence of fluid

Recess Depth Optimization for Rotating, Annular, and Circular Recess Hydrostatic Thrust Bearings

Journal of Tribology, 2010
Inertial effects due to the centripetal forces may become dominant at high rotational speeds in hydrostatic thrust bearings. Although this influence has been recognized in literature, bearings are commonly optimized with respect to the minimum friction ...

Characteristics of a hydrostatic thrust bearing

International Journal of Mechanical Sciences, 1962
Summary The static and dynamic behaviour of a hydrostatic thrust bearing has been fully analysed starting from the Navier-Stokes equations for two-dimensional flow. An expression has been derived giving the force exerted by the oil in terms of the variables, amplitude of vibration, thickness of oil film and frequency.

Pressure Measurements for Translating Hydrostatic Thrust Bearings

International Journal of Fluid Power, 2005
AbstractThe objective of this study is to take insitu measurement of the pressure profile that exists between a sliding thrust bearing and a stationary thrust surface. Using a two-dimensional model of the bearing and the classical one-dimensional Reynolds equation, the experimental results are explained and the minimum fluid film thickness and the tilt

Film Recession in Hydrostatic Thrust Bearings

Proceedings of the Institution of Mechanical Engineers, 1973
In general, hydrostatic thrust bearings are designed to operate with parallel bearing surfaces and it is assumed that the lubricant film completely fills the bearing clearance. In practice, bearings almost inevitably operate in a tilted condition and this modifies the behaviour of the bearing. In addition, when the surface approaching the bearing under

An Experimental Analysis of Hydrostatic Thrust Bearing

Journal of the Association of Engineers, India, 2011
Hydrostatic lubrication is a type of fluid lubrication where the bearing surfaces are kept separated by a film of fluid. The pressure which supports the load on the bearing is supplied to the film by an external source like pump, accummulator etc.
