Eccentric operation of conical hydrostatic thrust bearings

Wear, 1983
Abstract A theoretical study of the behaviour of capillary-compensated annular recess conical hydrostatic thrust bearings under conditions of eccentricity and rotation is reported. The influence of aspect ratios, cone angles and resistance ratios on the static and dynamic characteristics is discussed.

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

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. For parallel surface bearings of constant film thickness the inertia effects are found to be detrimental to load capacity.

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 ...

Inertia-induced cavitation in hydrostatic thrust bearings

Wear, 1961
Abstract The critical rotational speed at which inertia-induced cavitation is initiated in the lubricant film of hydrostatic thrust bearings is established. The lubricant mass flow and bearing load capacity at speeds exceeding this critical are determined and presented in the form of master plots of flow and load for all speeds.

A rotating field mhd hydrostatic thrust bearing

Applied Scientific Research, 1969
It is found that the load capacity of a magnetohydrodynamic thrust bearing with a rotating disk can be increased by rotating the axial magnetic field at a suitable speed in a direction opposite to that of the disk rotation. This method of improving the bearing performance is considered to be efficient if the Hartmann number is not too large. Thus for a

HYDROSTATIC THRUST BEARING WITH REDUCED POWER LOSSES

Tribologia, 2018
In many cases in rotating machinery, axial load is carried by tilting pad thrust bearings which have been developed since the beginning of 20th century. For high reliability and simplicity, most commonly the bearings are bath lubricated. In the times of sustainable development, however, minimization of friction losses becomes an important criterion for

The MHD Hydrostatic Thrust Bearing—Theory and Experiments

Journal of Lubrication Technology, 1967
An analytical and experimental investigation is made of magnetohydrodynamic lubrication flow between parallel stationary disks in an axial magnetic field. The effect of the fluid inertia is analyzed by a single iteration of the appropriate differential equations.

Theoretical and Experimental Analysis of Hydrostatic Thrust Bearings

Journal of Basic Engineering, 1960
This paper presents theoretical and experimental analysis of two types of circular hydrostatic thrust bearings, using incompressible lubricants. Design equations for load-carrying capacity, stiffness, and flow, are given for three different types of flow restriction—orifice, capillary, and constant flow.

Adiabatic solution of a tilted hydrostatic thrust bearing

Wear, 1983
Abstract Solutions are presented for thermal effects on tilted hydrostatic thrust bearings. The governing Reynolds equation is solved simultaneously with the adiabatic energy equation by finite difference methods. The results show that thermal effects are significant at higher values of the bearing number and the tilt parameter.
