Non-parallel 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 tilt and rotation was made. The influences of aspect ratios, cone angles and resistance ratios on the static characteristics and stiffness and damping coefficients are reported.

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.

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.

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.

Energy Integral Approach for MHD Hydrostatic Thrust Bearing

Journal of Lubrication Technology, 1975
An attempt has been made to investigate the bearing characteristics by energy integral approach (an approximate technique) and the results so obtained are compared with those of Krieger, Day and Hughes [1], for normalized flow rate and normalized load capacity.

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.

Heat-Transfer Effects in Hydrostatic Thrust-Bearing Lubrication

Journal of Fluids Engineering, 1957
Abstract The limiting isothermal and adiabatic operating conditions of the hydrostatic thrust bearing have been investigated recently. However, the actual performance of such bearings is characterized by an intermediate situation in which heat transfer occurs in the lubricant and bearings.

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

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
