ABSTRACT:
A hydrodynamic bearing constructed entirely of non-newtonian fluidic materials such as rubber, plastic and the like. The bearing is extrudable and includes a bearing pad support structure and a plurality of bearing pads formed with bearing pad support structure. The bearing pads may be formed of a material which is softer than the support structure. The bearing may also include a number of deflection control members fused to the bearing pads and/or the bearing pad support structure.
The method of making the bearing inlcudes the steps of extruding one or more materials to form an uncured tubular extrusion, curing the tubular extrusion, cutting the tubular extrusion into bearing segments and sizing the bearing segments by machining the individual segments to the desired inner and outer diameters.
