Evaluation and correction methods for geometric errors of hydrostatic thrust bearings. [PDF]
Sci RepThe value and direction angle of the perpendicularity error of the thrust surface and bearing bush in hydrostatic thrust bearings directly affect the motion accuracy. In this paper, a rapid onsite measurement method and evaluation model for the value and direction angle of the perpendicularity error of the thrust surface and bearing bush in hydrostatic

Optimization of Hydrostatic Thrust Bearings
Journal of the Japan Society of Precision Engineering, 1978 In this paper, the theoretical studies on the optimization of the operating condition of the hydrostatic thrust bearings are presented. Total amount of power consumption is treated as an objective function, while the bearing clearance, static stiffness, damping ratio of the bearing, lubricant viscosity and the initial lift up pressure are considered as

Theoretical Study of Hydrostatic Thrust Bearings
Bulletin of JSME, 1958 The load capacity of hydrostatic bearings can be increased by making a pocket which keeps effective fluid pressure on the bearing surface, and their dynamic stability can be improved by arranging a suitable restrictor like a capillary or an orifice which corresponds to the bearing dimensions and the optimum clearance in the fluid supply-line.

Thermoelastohydrodynamic Behavior of Hydrostatic Thrust Bearings
Hydraulics & Pneumatics, 1990 The thermoelastic behavior of hydrostatic thrust bearings is analyzed numerically. Mineral oils, HWCF, seawater, and tap water are studied as working fluids. The physical properties of these fluids are expressed as a function of temperature and pressure. The heat transfer and thermoelastic distortion of the bearings are considered.

Thrust bearing with a hydrostatic floating disk.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1989 This paper is concerned with the reduction of the power loss of the thrust bearing. A thrust bearing with a disk floated by externally pressurized oil is proposed, and the static characteristics of the thrust bearing are investigated by experiments and simplified analysis in the laminar regime.

Advanced Engineering Materials, EarlyView.This work studies the anisotropic behavior of circular notched tensile specimens of Ni‐base superalloy single crystals during high‐temperature tensile creep along [001], [110], and [111]. Correlative scale‐bridging imaging of specimens reveals early rupture along [110] because 1) plastic deformation proceeds faster at notch center; 2) more (brittle ...

Turbulent lubrication for hydrostatic thrust bearing with a circular recess.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1987 This paper is concerned with the characteristics of hydrostatic thrust bearings operating in the turbulent regime. Using the calculated results of the three-dimensional turbulent mean velocity between a rotating disk and a fixed wall as already proposed, the pressure distribution, the load capacity and the oil flow rate of the hydrostatic thrust ...
