| 摘要 |
A hydrodynamic journal bearing including a rotary journal shaft which is circular in cross section, a journal bearing surrounding the journal shaft and having at least two arcuate bearing surfaces, each arcuate surface defined by a radius slightly greater than that of the journal shaft so that the journal shaft will be in lubricated contact with at least the mid portion of each arcuate bearing surface while the ends of each arcuate bearing will be spaced from the surface of the rotary journal shaft, and seals to assure that lubrication almost completely fills all spaces between the rotary journal shaft surface and that of the journal bearing surface.
