A combination (12) comprises a belt (14) trained about a plurality of pulleys (16, 18) and a tensioner assembly (10) including a rotary member (30) rotatively engaged by one side of the belt (14) at an operative position. The rotary member (30) is rotatably mounted on an arm (20) pivoted about a fixed pivotal axis (41) and has a rotational axis (31) parallel with the fixed pivotal axis (41). The vector force (70) applied by the belt (14) to the periphery of the rotary member (30) at the bisector of the belt wrap angle (72) extends through the rotational axis (31) and is related by at least a small angle (74) to a line (76) passing through the rotational (31) and pivotal axis (41). The vector force (70) acts in a direction to bias the arm (20) to pivot about the pivotal axis (41) in a direction to move the rotary member (30) into the operative position. The rotary member (30) is initially installed into the operative position by moving the arm (20) in the direction from an installation position.
L'invention concerne une combinaison (12) comprenant une courroie (14) entraînée autour de plusieurs poulies (16, 18) et un ensemble tendeur (10) comportant un élément rotatif (30) couplé rotatif à un côté de la courroie (14) en position fonctionnelle. L'élément rotatif (30) est monté rotatif sur un bras (20) pivotant autour d'un axe de rotation fixe (41) et comprend un axe de rotation (31) parallèle à l'axe de rotation fixe (41). La force vectorielle (70) appliquée par la courroie (14) sur le pourtour de l'élément rotatif (30) au niveau de la bissectrice d'un angle de contact (72) s'étendant à travers l'axe de rotation (31) et étant relié par au moins un petit angle (74) à une ligne (76) passant à travers les axes de rotation (31) et (41). La force vectorielle (70) agit dans une certaine direction afin de polariser le bras (20) pivotant autour de l'axe de rotation (41) dans une certaine direction afin de déplacer l'élément rotatif (30) dans la position fonctionnelle. L'élément rotatif (30) est initialement installé en position fonctionnelle par mouvement du bras (20) dans ladite direction à partir d'une position d'installation.
