Patent ID: 8568034

Claim:
A bushing installation comprising: a workpiece having an opening, the workpiece including residual compressive stresses in a portion of the workpiece surrounding the opening; an outer member in an installed, radially expanded configuration positioned in the opening, the outer member having an inner surface and an outer surface, the inner surface having an inner perimeter and defining a passageway, the outer surface having an outer perimeter forming an interference fit with the workpiece; and an inner member positioned in the passageway of the outer member, the inner member having an outer surface forming an interference fit with the inner surface of the outer member, the inner member both supporting and limiting radial contraction of the outer member from the installed, radially expanded configuration, the inner member including an inner surface that defines a passageway through the inner member, the inner surface including a coating, plating, or lining that is unaltered from the installation of the inner member and the outer member in the workpiece, wherein the outer member is configured to elastically contract from an intermediate, radially expanded configuration to the installed, radially expanded configuration so as to form the interference fit between the outer member and the inner member.
