Abstract

L'invention concerne un tendeur (10), destiné à une courroie sans fin, qui comprend une structure fixe sur laquelle est monté un bras de tension (13) rotatif pourvu d'une poulie de renvoi (11). Un ressort (15) situé entre le bras de tension (13) et la structure fixe (16) sollicite la poulie (11) contre la courroie, et applique ainsi une tension. L'invention concerne un dispositif unidirectionnel utilisable en réponse à l'étendue du mouvement rotatif du bras de tension (13) dans un sens, afin d'établir différentes positions dans lesquelles le mouvement rotatif en sens inverse est limité. Un système d'amortissement (44) est utilisé afin de resteindre le mouvement rotatif du bras de tension (13) suite à des mouvements vibratoires soudains de courte durée ou à des vibrations dynamiques dans des conditions à froid.
