Abstract
A compliant hydrodynamic fluid journal bearing includes a bearing sleeve having a cylindrical bore which receives a bearing sheet having a radially inwardly facing bearing surface. The bearing sheet is supported by a compliant support element having spaced resilient projections for resiliently supporting the bearing sheet. One end of the support element is welded adjacent to one end of the bearing sheet with an intervening spacer block, and the assembly is fixed in the bearing sleeve. A second block is welded adjacent to the other end of the bearing sheet so that the ends of the bearing sheet extend slightly beyond the blocks. A spring is disposed between the two blocks and is retained in place by the bearing sheet overhangs. The spring exerts a circumferential spreading force on the two blocks and through them on the two ends of the bearing sheet. This spreading force holds down the ends of the bearing sheet for two-way shaft rotation, and has the effect of seating the bearing sheet firmly against the support element, and the support element firmly against the bearing sleeve for bearing clearance control and optimized damping.
