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.

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).

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.

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

The pressure distribution in a hydrostatic thrust bearing

International Journal of Mechanical Sciences, 1965
Abstract An expression is obtained for the pressure distribution in a hydrostatic thrust bearing using an existing series expansion solution for radial flow between parallel planes. It is shown that the same result can be obtained by a simple uni-directional flow analysis. The present results are compared with those of earlier investigations in which

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.

The thermohydrodynamic flow equations for hydrostatic thrust bearings

Meccanica, 1970
This paper studies the flow in rotating hydrostatic thrust bearings lubricated with incompressible fluids under pressure. It considers, besides the effects of inertia on the lubricant, its increase in temperature in the film due to fluid friction (thermohydrodynamic flow).

The dynamic characteristics of a hydrostatic thrust bearing

International Journal of Machine Tool Design and Research, 1961
Abstract The dynamic behaviour of a hydrostatic thrust bearing is subjected to a relatively simple analysis, based on an equivalent spring-damper system. The validity of this approach is justified with results obtained from an experimental investigation. The results indicate that the dynamic stiffness of a massless system is at all times greater than

Performance study of a hydrostatic air thrust bearing

Wear, 1981
Abstract In this paper we present the results of an extensive experimental investigation into the performance of a capillary-compensated hydrosatic six-pocket air thrust bearing under static loading and at different journal rotational speeds. The supply pressure ranged from 114 to 276 kPa and the applied load ranged from 53 to 623 N.

Design of tilted hydrostatic thrust bearings

Wear, 1981
Summary Hydrostatic bearings are usually designed to operate under parallel conditions, but structural and thermal deformations cause tilting of the pad. A semianalytical solution of the pressure equation is used. It is shown that tilting of hydrostatic thrust bearings gives rise to negative pressures and that cavitation may occur depending on the tilt
