Abstract

La présente invention se rapporte à un ensemble pour la mise en place d'une courroie, qui empêche la torsion pendant la mise en place d'une courroie. Plus particulièrement, un ensemble (1) pour la mise en place d'une courroie est doté d'un moyen de fixation (6) destiné à être fixé à une poulie (2). Une surface de retenue (8) est conçue pour recevoir une partie d'une courroie (4) et retenir ladite courroie (4) plus à l'extérieur dans la direction de l'axe de la poulie que ne l'est un flasque (7) de poulie. Une pièce (10) empêchant la torsion est utilisée pour empêcher la torsion de la courroie (4). Cette pièce (10) empêchant la torsion se trouve plus en avant dans la direction de rotation de la poulie (2) que ne l'est la surface de retenue (8), et plus à l'extérieur dans la direction de l'axe de la poulie que ne l'est la poulie (2). Ladite pièce (10) empêchant la torsion empêche la torsion à l'endroit où la courroie (4) passe entre les poulies (2, 3) par l'extérieur dans la direction de l'axe de la poulie (2).
