Abstract

L'invention porte sur un outil de montage de courroie qui permet de monter facilement une courroie sur une poulie, même si l'espace existant sur un côté de la poulie est insuffisant. Plus précisément, une section de montage (9) est formée d'une section de recouvrement (8) et de l'extrémité d'une vis de réglage (13) qui sert de section de saisie. Un outil de montage de courroie (1) est monté sur une poulie (5) par la section de saisie qui saisit la poulie (5) à la fois par le côté périphérique intérieur d'un évidement (10) présent dans une surface latérale de la poulie (5) et par le côté périphérique extérieur de la gorge (3) de la poulie. Une courroie (2) mise en prise avec la gorge (3) de la poulie est recouverte par la section de recouvrement (8) en partant du côté périphérique extérieur. La courroie (2) est enfoncée vers le fond de la gorge (3) de la poulie. La courroie (2) est empêchée de s'échapper de la poulie (5). La poulie (5) est tournée pour entraîner l'accessoire de montage de courroie (1) avec la poulie (5). Une zone de plus en plus grande de la courroie (2) est mise progressivement en prise avec la gorge (3) de la poulie et la courroie (2) est montée sur la poulie.
