A REVOLUTIONARY DEVELOPMENT IN ROTATING BEARINGS
The Swing-Pad Bearing, a new basic form of a lubricated rotating bearing invented at the David W. Taylor Naval Ship Research and Development Center, is expected to have significant impact on the design of machinery for future ships. The novelty of the Swing-Pad Bearing form is that the friction force itself is used to deflect the bearing surface to produce the converging wedge. The stationary bearing surface is segmented. Each segment is a "pad." These pads are supported by curved segments of laminated elastomer with the center of the curvature located above the pad bearing surface. The laminated elastomer, stiff in compression and soft in shear, will support the bearing load and allow the pads to displace around the center of the curvature, swinging their surfaces to admit lubricant at the leading edges. This forms a load-carrying wedge of fluid. The pads displace through a motion resembling a swing. The construction is simple, rugged, and inexpensive. Included are diagrams and drawings illustrating the construction and operation of the bearing.
