초록

The top foil (12) of the hydrodynamic fluid film journal bearing (10) carries opposing tabs (23,25) at the side edges adjacent the free end (17) thereof and extends radially outward to fit adjacent to the side edges (19,21) of the intermediate foil 14 and the ends of the key 18 when rolled into a cylinder and inserted into the bore of sleeve (24) to prevent skewing of the top foil. In another embodiment skewing is prevented by incorporating opposing tabs (37,39,50,52) at the free ends (31,54) of the top foil (12a) and intermediate foil (14a) that project...
