Abstract

This air bearing is manufactured of materials which are lightweight and compatible. The air bearing consists of plenum 10 supplied with air or inert gas at above ambient pressure, by conduit 12 from a source, not shown. Bearing plate 14, shown broken away, includes a plurality of holes in a desired pattern. Plenum 10 and bearing plate 14 are connected by a heat curable adhesive. The plenum chamber may include one or more partitions 16 which support and stiffen bearing surface 14. The bearing surface has a thickness of between about 0.005 to 0.020 inch.

Air Bearing Construction

This air bearing is manufactured of materials which are lightweight and compatible. The air bearing consists of plenum 10 supplied with air or inert gas at above ambient pressure, by conduit 12 from a source, not shown. Bearing plate 14, shown broken away, includes a plurality of holes in a desired pattern. Plenum 10 and bearing plate 14 are connected by a heat curable adhesive. The plenum chamber may include one or more partitions 16 which support and stiffen bearing surface 14. The bearing surface has a thickness of between about 0.005 to 0.020 inch.

Adhesive bonding between the air bearing plate 14 and plenum 10 is with moderate temperature curing modified epoxy, nylon modified epoxy, or epoxy- phenoxy. The adhesive is preferably in a solvent solution form and coated on the portions of the plenum 10 and/or bearing surface where connection is to be made, while avoiding blocking the air holes. After the adhesive is applied to the parts and dried, the surface and plenum are clamped together and heated to a temperature sufficient to cure the adhesive. Alternatively, nitrile phenolic is coated on selected portions of the plate or plenum 10 and temperature cured. Subsequently, modified epoxy is applied to matching portions of the other part. The parts are then clamped together and heated at a low temperature to complete curing.

The material of choice for bearing plate 14 is nonmagnetic stainless steel. Holes in the bearing surface are prefer...
