Abstract

L'invention concerne un procédé de fixation d'une douille sur un arbre, en particulier un procédé de fixation d'une douille respective (28, 30) sur l'arbre d'entrée (12) et l'arbre de sortie (14) d'un capteur de couple (10). L'arbre présente un contour pour l'assemblage avec la douille (28, 30) par déformation plastique. Une région repoussée (36a, 36b) est ici formée sur l'arbre (12, 14) comme partie d'un contour négatif (32, 34, 36) et la douille (28, 30) est enfoncée aux fins de blocage dans le contour. L'ensemble du contour ne dépasse pas du diamètre de l'arbre (12, 14), permettant ainsi une rotation et/ou une translation relative de la douille (28, 30) pour l'ajustement fin avant le blocage définitif.
