This report introduces a new bearing concept, the swing-pad bearing. The concept is a sliding-surface lubricated bearing in which the stationary bearing surface is segmented into pads that can displace through a motion resembling a swing to form a wedge-shape converging in the direction of motion with the rotating member. Viscous friction force moments are in the direction to form the converging wedge-shape fluid pressure force moments oppose wedge formation. The pad bearing surface stabilizes at a position where these moments are in balance. Exploratory experimental investigations conducted on model elastomer surface swing-pad bearings indicate exceptional performance characteristics. These characteristics are 1 low coefficients of friction representative of fluid lubrication under loadspeedfluid viscosity combinations that would produce boundary lubrication in conventional bearings 2 operation at rotational start-up and at extremely low speeds with applied loads that would cause stick-slip motion and squeal in conventional bearings.
