ABSTRACT:
A hydrodynamic compliant journal bearing for dynamically supporting a rotating shaft in a journal sleeve, includes three pads, each having a flexible bearing sheet attached to the sleeve along one edge and a resilient supporting structure attached to the sleeve under the bearing sheet for compliantly supporting the bearing sheet to support the shaft. The resilient support has a series of resilient elevations which increase in stiffness in the direction of shaft rotation so that the pad assumes a profile under hydrodynamic loading which increases in inclination with increasing shaft speed to maintain bearing stability over the full load range.
