Abstract
A hydrodynamic fluid film journal bearing assembly includes a journal sleeve having a key slot formed therein in a substantially longitudinal direction, a bump foil wrapped in a substantially cylindrical shape adjacent to the journal sleeve and having a bent end portion engaged with the key slot, an intermediate foil wrapped in a substantially cylindrical shape adjacent to the bump foil, a top foil wrapped in a substantially cylindrical shape adjacent to the intermediate foil, a first top foil cutout window formed adjacent to the bent region, and a first end tab formed at a free end of the top foil. The first end tab is wrapped with the top foil in the substantially cylindrical shape of the top foil, and extends into the first top foil cutout window to reduce skewing. The top and intermediate foils are joined at a bent region that engages the key slot.
