ABSTRACT:
A compliant hydrodynamic fluid film bearing includes a flexible bearing sheet overlying and supported by a resilient support element having two corrugated spring foil support elements arranged in a staged, parallel spring array. The top spring element is more compliant in the bottom spring element and provides a compliant support for the bearing sheet at low rotor speeds to provide early development of load bearing capacity. With increasing rotor speed, the top support element deflects to the level of the second or lower support element which is stiffer and provides stronger support at higher speeds. At these higher speeds, the combined support element supports the bearing sheet at the correct profile to the moving bearing member and prevents collapse of the support element so that the bearing remains operative at high and ultra high speeds despite the increased load and stiffness of the hydrodynamic fluid film.
