Designing the Partially Porous Journal Bearings of an Aerostatic Spindle
Applied Mechanics and Materials, 2017 The aerostatic journal bearings are widely used in ultra-precision machine tools. Due to remarkable ability of the porous medium in flow restriction, the porous aerostatic journal bearings are better than other types of aerostatic bearings in load carrying capacity, stiffness, damping and dynamic stability.

Dynamic Characteristics of Aerostatic Porous Journal Bearings With a Surface-Restricted Layer
Journal of Tribology, 2010 Aerostatic porous bearings have been successfully applied to various precision devices such as machine tools and measuring equipment to achieve a higher accuracy of motion. However, aerostatic porous bearings have a disadvantage in that they are prone to cause pneumatic hammer instability.

Static characteristics of aerostatic porous journal bearings with a surface-restricted layer
Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology, 2003Graphite porous materials have been successfully used in an aerostatic bearing. This is because graphite porous materials have a lower permeability than porous metal, which makes it possible to achieve a higher stiffness in aerostatic bearings. However, aerostatic porous bearings have a disadvantage in that they are prone to cause pneumatic hammer ...

Recently, aerostatic porous bearings have been used in ultra precision machine tools and precision-measuring equipment because they have higher stiffness and larger damping coefficients than other types of aerostatic bearings. However, an aerostatic porous bearing has a disadvantage in that it is prone to cause pneumatic hammer instability.

Key Engineering Materials, 2017 The influence of the spacing of the partially porous aerostatic journal bearings and the rotating speed of the spindle on the pressure distribution in the bearing gap and the housing gap were studied. Based on the finite volume method and the pressure-velocity coupling scheme of the SIMPLE algorithm with the standard k-ε turbulent model, A CFD software

Abstract Numerical and experimental research on the effects of manufacturing errors on the static performance of aerostatic porous journal bearings is presented. The effects of circumferential waviness, taper, concavity, and convexity on the bearing film thickness were modeled based on the experimental results.
