A hydrodynamic fluid film journal bearing assembly (10) includes a journal sleeve (12) having a key slot (22) formed therein in a substantially longitudinal direction, a bump foil (28) wrapped in a substantially cylindrical shape adjacent to the journal sleeve and having a bent end portion (34) engaged with the key slot, an intermediate foil (30) wrapped in a substantially cylindrical shape adjacent to the bump foil, a top foil (32) wrapped in a substantially cylindrical shape adjacent to the intermediate foil, a top foil cutout formed in the top foil adjacent to the bent region, and an end tab (48) formed at a free end of the top foil. The end tab is wrapped with the top foil in the substantially cylindrical shape of the top foil, and extends into the top foil cutout to reduce skewing. The top and intermediate foils are joined at a bent region (38) that engages the key slot. |
