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.
