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.

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.

Rubber supported hydrostatic thrust bearings with rigid bearing surfaces

Tribology International, 1997
Abstract The film pressure of tilted hydrostatic thrust bearings results in a tilt opposing moment. This self-aligning action of the tilt opposing moment can be used effectively to reduce the deflection of the film contour. For this reduction some adjustment (elasticity) of the bearing system is necessary.

Centrifugal Effects in Hydrostatic Porous Thrust Bearing

Journal of Lubrication Technology, 1979
In this analysis the customary neglected centrifugal effects on the performance of hydrostatic porous thrust bearing with incompressible lubricant has been studied and the effects of their interaction of pressure distribution and load capacity illustrate the possibility of replacement of the nonporous bearing material by porous one.

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

Control Method of Heavy Hydrostatic Thrust Bearing

2009 International Conference on Intelligent Human-Machine Systems and Cybernetics, 2009
A hybrid fuzzy control scheme was applied to improve the rigidity of hydrostatic thrust bearing. The bearing oil film control was realized by coupling oil film thickness of four controllable chambers. The chamber flow can be regulated by electro hydraulic servo valve-control variable pump according to the surface roughness, load, cutting force, and ...

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.

Experimental assessment of hydrostatic thrust bearing performance

Tribology International, 1996
This work presents an experimental study to assess the performance characteristics of hydrostatic thrust bearings. A test rig is designed for testing two configurations of hydrostatic bearings compensated by a capillary tube, one with a mid-circular recess and the other with multi-sectors (four recesses of different recess radii ratios).
