An improved and enhanced hydrodynamic fluid film bearing (110) for rotatably supporting a shaft journal (114) is provided and includes a stationary retaining member (112), at least two generally cylindrical foil elements (120,124) attached to one another and forming an anti-rotation fin (130), and a generally cylindrical resilient backing (126) member. The retaining member (112) has an inner surface defining a cylindrical opening (116) for receiving a shaft journal (114). The inner surface also includes a longitudinally extending slot (118) in which the anti-rotation fin (130) formed by the foil elements (120,124) is mounted so that the foil elements (120,124) line at least a portion of the cylindrical opening (116). The resilient member (126) is also disposed within the cylindrical opening (116) generally concentric to and radially outward from the foil elements (120,124). The foil elements (120,124) may be discrete elements attached together to form the anti-rotation fin (130), or alternatively formed from a single foil with a bend defining the anti-rotation fin (130). |
