Performance of Hydrostatic Spherical Gas Gyro Bearings

Journal of Lubrication Technology, 1976
Analysis and method of numerical solution for evaluating the performance of hydrostatic spherical gas gyro bearings at any gimbal angle and at any eccentricity have been developed. Performance data on load capacity, gas flow rate, drag torque, and error torque over some ranges of gimbal angle and eccentricity are presented.

Hydrostatic Gas Bearings

Journal of Basic Engineering, 1960
Orifice-regulated hydrostatic gas bearings offer significant advantages for instrument applications. In particular, gimbal bearings for inertial guidance systems can be designed with negligible starting torque and high stiffness, and for operation at extreme temperatures.

Investigation of the Spherical Hydrostatic Gas Bearing for Two-Axis Gyros

Journal of Lubrication Technology, 1971
Investigation shows that spherical hydrostatic gas bearings can be manufactured by coining of precision dimensions in aluminum die castings. The paper also shows that the goals of low competitive costs and high reliability can be achieved with commercial balls, filters, and gas cartridges.

Design Study of a Hydrostatic Gas Bearing With Inherent Orifice Compensation

Journal of Fluids Engineering, Transactions of the ASME, 1957
Abstract A hydrostatic gas bearing can provide shaft support with very low friction in high-speed devices such as centrifuges and gyroscopes and in precision static devices such as dynamometers. For comparable load conditions, the friction torque required to rotate a hydrostatic bearing is from 100 to 10,000 times less than the friction ...

The Hydrostatic Gas Journal Bearing With Journal Rotation and Vibration

Journal of Basic Engineering, 1964
This paper analyzes the load-carrying capacity of the externally pressurized gas journal bearing, including the effect of journal rotation and vibration. The analysis assumes small eccentricity ratio and small vibration amplitude such that a first-order perturbation solution is obtained.
