<p>The hydrodynamic bearing for journalled a shaft, comprises a bushing supported in a sleeve and journalling the shaft, and thrust plates on the shaft at opposite ends of the bushing. The bushing, shaft and thrust plates defines a clearance space between them for containing a lubricant. An internal helical channel is defined between the bushing and the sleeve and opening at the axial ends of it to the clearance space between the thrust plates and the bushing. A port through the bushing opening into the helical channel provides lubricant flow through the journal bearing and the clearance space. The bushing and sleeve define a number of internal helical channels.</p> |
