The MHD Hydrostatic Thrust Bearing—Theory and Experiments
Journal of Lubrication Technology, 1967An 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, 1960This 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.

A non-central feeding hydrostatic thrust bearing
Journal of Fluid Mechanics, 1975In 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.

Eccentric operation of conical hydrostatic thrust bearings
Wear, 1983Abstract 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.

HYDROSTATIC THRUST BEARING WITH REDUCED POWER LOSSES
Tribologia, 2018In 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

Rubber supported hydrostatic thrust bearings with rigid bearing surfaces
Tribology International, 1997Abstract 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.

Static Load Performance of a Water-Lubricated Hydrostatic Thrust Bearing
Journal of Engineering for Gas Turbines and Power, 2017In rotating equipment, thrust bearings aid to balance axial loads and control shaft position. In turbomachinery, axial loads depend on shaft speed and pressure rise/drop on the impellers. This paper details a water-lubricated test rig for measurement of the performance of hydrostatic thrust bearings (HTBs).

Inertia Effects in MHD Hydrostatic Thrust Bearing
Journal of Lubrication Technology, 1969An approximate analytical study is made of inertia effects in magnetohydrodynamic lubrication flow between two parallel disks, one of which rotates at a constant angular velocity in an axial magnetic field. Fairly good accuracy of the approximate solution is confirmed in the special limiting case of zero rotating speed.

Adiabatic solution of a tilted hydrostatic thrust bearing
Wear, 1983Abstract 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.
