ABSTRACT:
A fluid bearing with a multicomponent membrane which is inflated to form a torus defining a plenum chamber. The preferred three layer membrane has a fluid impermeable inner layer, a middle layer of a dimensionally stable fabric, and an abrasion resistant outer layer. The layers may be replaced independently. A number of different mechanisms for attaching the layers to the load-carrying member of the bearing are shown, and different membranes having different lift heights may be used with a single load-carrying member. In one embodiment one of a series of interchangeable metal rings of different diameters used with the middle layer of the membrane may be selected to control the lift height. The bearing also includes a replaceable orifice plate which controls the rate of flow into the plenum chamber and into and out of the torus membrane. A valve operates during the usual gradual start up to block flow of fluid to the plenum until the pressure in the torus membrane is one or two p.s.i. above atmospheric.
