ABSTRACT:
A hydrodynamic bearing which includes a carrier and a plurality of bearing pads circumferentially spaced about the carrier. The carrier is formed with a series of circumferentially spaced groups of pad support openings. Each group of pad support openings includes two or more pad support openings each of which is capable of supporting a pad, but only one of which supports a pad at any one time. The carrier is designed such that the openings formed therein are supported as sets of supports such that each group of openings includes one opening of each set of openings. The carrier supports the openings such that the support of each opening within each set is substantially identical to that of the other openings in its set, but different than the support of the openings of other sets such that each set of bearing pad openings is adapted to support bearing pads for a distinct characteristic deflection.
