AIR BEARING STRUCTURE

摘要

An air bearing structure, which is a porous air bearing. In the air bearing structure, a porous material is combined with an aluminum layer with vents to provide double restrictions so as to enhance the degree of freedom in adjusting the diameter parameter of porous material. The vents are distributed in a matrix pattern and have a diameter of nanometer order. Therefore, the uniformity of the vents and the unification of the infiltration can be ensured. Also, the vents can be directed in the same direction to enhance the bearing ability, air film stability and static rigidity.

主权项

1. An air bearing structure comprising:
a porous main body having a base section and an air cavity formed in the base section, the air cavity being composed of multiple voids formed in the base section in communication with each other; and a throttling layer section disposed on one face of the porous main body, the throttling layer section being formed of an aluminum layer having multiple vents with predetermined length, the vents passing through the aluminum layer and being directed in the same direction in communication with the air cavity.
