Abstract

L'invention vise à maîtriser, en cas d'étirement nécessaire, les forces importantes à appliquer sur une pièce support lors du montage d'éléments (10) annulaires externes pouvant changer de diamètre, en particulier de bagues d'étanchéité présentant un petit diamètre nominal de préférence inférieur à 5 mm, ainsi qu'à prévenir, lorsque les dimensions des bagues et la solidité des cordons deviennent de plus en plus faibles, tout danger de pincement de la bague d'étanchéité au niveau des segments racleurs et d'endommagement de l'étanchéité. À cet effet, la bague d'étanchéité (10) est élargie au moyen d'un cône de montage (1) introduit dans un masque de montage (7). Pour cela, la bague d'étanchéité (10) est amenée par un outil d'étirement de type pince (13) de l'extrémité pointue (4) à l'extrémité cylindrique (3) du cône de montage (1), le cône de montage (1) étant coulissé hors du masque de montage (7) et maintenu fixement par un outil de maintien et de positionnement (11). Le montage final de la bague d'étanchéité (10) dans la rainure annulaire d'une pièce support a lieu finalement sans étirement supplémentaire, de telle sorte que la pièce support presse à nouveau le cône de montage (1) dans le masque de montage (7), ce dernier enlevant la bague d'étanchéité (10) du cône de montage (1) dans la rainure annulaire.
