Research on Controlled Hydrostatic Bearing

Transactions of the Japan Society of Mechanical Engineers, 1964
For controlled hydrostatic bearings having variable restrictions, it is possible to make their static stiffness increase greatly by means of the automatic regulation of recess pressure; namely the recess pressure controlled by a spool valve rises rapidly according to the displacement of journal or shaft, thus the bearings possess very high load ...

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
