Abstract

L'invention concerne un composant et une structure de raccord de fixation, un procédé de montage pour la structure de raccord de fixation, un procédé de retrait pour celle-ci et un mécanisme de raccordement de vilebrequin et une structure de piste comprenant la structure de raccord de fixation. La structure de raccord de fixation comprend un parent (15), une fixation (16) et un composant de raccord de fixation. Le composant de raccord de fixation comprend un boulon fileté (1), un écrou de fixation (2) et un manchon d'arrêt de rotation (3). Sur la paroi d'un premier trou d'arrêt de rotation (18) et/ou le manchon d'arrêt de rotation (3) se trouve une structure d'extraction (23) servant à extraire le manchon d'arrêt de rotation (3). La tige filetée (1) s'étend à travers le parent (15) et la fixation (16) pour venir se raccorder par filetage avec l'écrou de fixation (2). Le manchon d'arrêt de rotation (3) est monté et limité axialement sur l'extérieur de l'écrou de fixation (2) et à l'intérieur du premier trou d'arrêt de rotation (18). Une première partie d'arrêt de rotation (5) sur la périphérie de l'écrou de fixation (2) ajuste une deuxième partie d'arrêt de rotation (12) sur la paroi d'un trou traversant d'arrêt de rotation (10) du manchon d'arrêt de rotation (3) pour restreindre la rotation de l'écrou de fixation (2) par rapport au manchon d'arrêt de rotation (3). Une troisième partie d'arrêt de rotation (14) sur la périphérie du manchon d'arrêt de rotation (3) ajuste une quatrième partie d'arrêt de rotation (20) sur la paroi du premier trou d'arrêt de rotation (18) pour restreindre la rotation du manchon d'arrêt de rotation (3) par rapport à la fixation (16). La tige filetée (1) et l'écrou de fixation (2) sont montés de manière non rotative avec la fixation (16) et le parent (15). Ainsi, l'écrou de fixation (2) ne tourne pas en sens inverse et ne se desserre pas par rapport à la tige filetée (1) et le manchon d'arrêt de rotation (3) peut être extrait de manière pratique, rapide et fiable à partir du premier trou d'arrêt de rotation (18).
