An aerostatic thrust bearing with a stiffness of
Nanotechnology, 1996This paper proposes a new type of aerostatic thrust bearing in order to achieve 10 times larger bearing stiffness compared with that of conventional aerostatic bearings. In this bearing, a porous restrictor with 1 - 3 mm diameter is employed instead of a conventional feed-hole restrictor to restrain gas flow entering the bearing clearance to a very ...

Improving the operation of aerostatic bearings
Russian Engineering Research, 2008Means of improving the performance of aerostatic bearings are considered. The existing methods are described in detail and classified. The basic approaches ensuring the maximum possible rigidity and carrying capacity, without loss of dynamic properties, are identified.

Active Aerostatic Bearings for Ultraprecision Applications
2007For ultraprecision applications, two types of active control restrictors for aerostatic bearings are evaluated. The first restrictor is called an aerostatically controlled restrictor (ACR), a bearing-pressure-feedback type. The change in the pressure on the bearing surface directly controls the restriction gap, and the stiffness of the aerostatic ...

Frictional characteristics of an aerostatic linear bearing
Tribology International, 2006Frictional characteristics of an aerostatic linear bearing are evaluated in detail by means of a developing method. In the method, the resultant force acting on the moving part of the bearing is measured highly accurately as the inertial force using an optical interferometer. The velocity dependence of dynamic friction is focused on in this paper.

Design Procedure for Flat Aerostatic Bearings
1976A generalised design procedure has been put forward for the design of single and multipocketed flat aerostatic bearings. This design procedure helps to minimise the air consumption without sacrificing any of the requirements. A set of graphs and nomograms have been proposed to quickly arrive at the correct solution for given data.
