IMPROVED HYDRODYNAMIC BEARING UNIT

摘要

A self-contained hydrodynamic bearing unit is disclosed. Centrifugal capillary seals are angularly defined between an outwardly tapered outer surface of a top screw (111) and an inwardly tapered inner surface of an annular clamp ring (187) at the top of the bearing unit as well as between an outwardly tapered outer suface of a seal plate (165) and an inwardly tapered inner surface of an annular clamp ring (167) at the bottom of the bearing unit.
