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).

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.

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.

Centrifugal Effects in Misaligned Hydrostatic Thrust Bearings

Journal of Lubrication Technology, 1983
An analysis is conducted and solutions are provided for the effect of centrifugal forces on hydrostatic misaligned thrust bearings. The results show that centrifugal forces reduce considerably the load capacity, the friction torque and increase the lubricant flow rate.

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

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.

Static Load Performance of a Water-Lubricated Hydrostatic Thrust Bearing

Journal of Engineering for Gas Turbines and Power, 2017
In 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).

A note on hydrostatic thrust bearings with offset load

Wear, 1973
Abstract The note outlines a general method of solution for a hydrostatic (externally pressurized) multi-recess thrust bearing with offset load using an incompressible lubricant.

Inertia Effects in MHD Hydrostatic Thrust Bearing

Journal of Lubrication Technology, 1969
An 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, 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.
