Static and Dynamic Characteristics of Cirular Aerostatic Porous Thrust Bearings.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1996
Recently brittle porous materials such as graphite and advanced ceramics have been used in the fabrication of aerostatic bearings because gas flow through these porous materials can be limited to a small amount. However, aerostatic bearings consisting of these porous materials are prone to cause pneumatic hammer instability. Therefore, it is considered

The Simulation of Gas Film Flow Field in Aerostatic Thrust Bearing

Sustainable Development Research
Based on the CFD software, the numerical simulation and visualization of the gas flow in the gas film gap are carried out. Considering the influence of gas flow, the laminar flow model was adopted when the clearance is relatively small and a realizable model was adopted for large gaps.

Numerical investigation on dynamic tilt characteristics of aerostatic thrust bearings

Journal of Physics: Conference Series
Abstract Aerostatic bearings are widely used in ultra-precision measurement due to their near-zero friction. However, their inevitable tilt can cause angular error motion, reducing the measurement system’s precision. This study establishes a dynamic model of the bearing’s tilt characteristics using the tilt-perturbed Reynolds equation ...
