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.

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

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.

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).

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

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.

A non-central feeding hydrostatic thrust bearing

Journal of Fluid Mechanics, 1975
In a conventional hydrostatic thrust bearing, the lubricant is supplied from the centre and flows radially outwards. It has been found that the load capacity of such a bearing decreases with increasing angular speed of the rotor. The bearing fails when a critical rotor speed is reached at which the load capacity becomes zero.

Non-parallel operation of rectangular hydrostatic thrust bearings

Wear, 1984
Abstract A theoretical study of the behaviour of capillary-compensated rectangular hydrostatic thrust bearings with tilt and sliding was made. The influence of the aspect ratio on the load-carrying capacity, flow and stiffness and damping characteristics is discussed.

Fluid-Inertia Effects in Spherical Hydrostatic Thrust Bearings

A S L E Transactions, 1967
This paper includes the predominant centripetal inertia terms in a comprehensive analysis of hydrostatic thrust bearings of spherical form. The analysis considers continuous spherical surfaces which are not interrupted by grooves and solutions are presented for spheres having radii equal to and less than the radius of the hemispherical seal.
