| Abstract: | The static performance of externally pressurized gas journal-thrust bearing with slot restrictors is investigated by the finite element technique. Some factors which influence the radial and axial bearing capacity are discussed, such as slot width and bearing clearance. The interactional rules that exist between thejournal part and thrust part are discovered. The pressure distribution in the bearing is also studied. |
