Abstract

L'invention concerne un entraînement à courroie (1) comprenant une courroie (6), au moins un disque pour élément de traction (2) entraînant et au moins un disque pour élément de traction (3) entraîné ainsi qu'un dispositif de tension (4) placé au niveau du brin de retour (8) de la courroie (1). Le ou les disques pour moyen de traction (2) entraînants et/ou le ou les disques pour moyen de traction (3) entraînés ont une forme ovale et/ou sont montés de manière excentrique. L'invention vise à augmenter davantage et au moins à pouvoir conserver le rendement d'un entraînement à courroie (1) de type susmentionné, qui le cas échéant, fonctionne déjà dans sa plage limite avec des moyens techniques simples et peu de matériaux. A cet effet, le dispositif de serrage (4) comprend un rouleau de tension (4a) ovale qui, de son côté, peut être réglé par un élément excentrique (7) en direction de la courroie (6) et pouvant être fixé, constitue un centre de rotation (9).
