Abstract

In this paper a novel design of aerostatic thrust bearing<br> is proposed and is analyzed numerically. The capillary restrictor and<br> bearing disk are made of elastomer like silicone and PU. The<br> viscoelasticity of elastomer helps the capillary expand for more air<br> flux and at the same time, allows conicity of the bearing surface to<br> form when the air pressure is enhanced. Therefore the bearing has the<br> better ability of passive compensation. In the present example, as<br> compared with the typical model, the new designs can nearly double<br> the load capability and offer four times static stiffness.
