Abstract

Un ensemble mécanique (100) comprend au moins des première et deuxième pièces axisymétriques (110, 120) assemblées l'une avec l'autre au niveau d'une zone de chevauchement de la première pièce sur la deuxième pièce. La première pièce axisymétrique (110) comprend une première rainure annulaire (111) présente sur la surface interne de la première pièce dans la zone de chevauchement avec la deuxième pièce. La deuxième pièce axisymétrique (120) comprend une deuxième rainure annulaire (121) présente sur la surface externe de la deuxième pièce dans la zone de chevauchement avec la première pièce. Les première et deuxième rainures (111, 121) étant en vis-à-vis l'une de l'autre. Au moins une tige (130) est présente à la fois dans les première et deuxième rainures annulaires (111, 121).
