At least one embodiment of the invention generally relates to a bushing kit (102) and method of installing the same with a mandrel (300) having a tapered region (304). The bushing kit comprises an inner member (110) and an outer bushing (108). The inner member may include an inner surface (126) having an engagement portion, such as a coating, plating, and/or lining, such as a self- lubricating coating. The method of installing the bushing kit (102) includes passing the tapered portion of the mandrel through the outer bushing (108) to radially expand the outer bushing into the structural workpiece (104) and possibly induce some amount of residual compressive stress in the structural workpiece (104). Contemporaneously, the inner member (110) is passed into the radially-expanded outer bushing (108) before the outer bushing is permitted to radially inwardly rebound or spring back. The outer bushing (108) is then permitted to radially contract onto the inner member to form an interference fit therewith.
Au moins un mode de réalisation de l~invention concerne généralement un kit de coussinets (102) et un procédé d~installation de celui-ci avec un mandrin (300) présentant une région taraudée (304). Le kit de coussinets comprend un élément interne (110) et un coussinet externe (108). L~élément interne peut contenir une surface interne (126) possédant une partie d~engagement, comme un revêtement, placage et/ou garniture, comme un revêtement autolubrifiant. Le procédé d~installation du kit de coussinets (102) consiste à faire passer la partie taraudée du mandrin à travers le coussinet externe (108) pour dilater radialement le coussinet externe dans la pièce d~usinage structurelle (104) et éventuellement induire une certaine quantité de contrainte de compression résiduelle dans la pièce d~usinage structurelle (104). Simultanément, l~élément interne (110) passe dans le coussinet externe dilaté radialement (108) avant que le coussinet externe ne puisse rebondir radialement rentré vers l~intérieur ou revenir par un effet de ressort. Le coussinet externe (108) peut alors se contracter radialement sur l~élément interne pour constituer un ajustement serré avec celui-ci.
