Abstract

L'invention concerne un tendeur conçu de telle sorte qu'un second élément d'arbre est propulsé de façon stable. Un premier élément d'arbre interne (3) et un second élément d'arbre externe (4), qui sont reliés par des sections de vis (8, 10), et un ressort de poussée (5) pour pousser le premier élément d'arbre (3) dans une direction, sont reçus dans un carter (2). La rotation du second élément d'arbre (4) est empêchée, et une force de poussée rotative du ressort de poussée (5) est convertie en force de propulsion du second élément d'arbre (4). Le premier élément d'arbre (3) est amené à tourner avec sa partie d'extrémité d'arbre directement ou indirectement en contact avec le carter (2). Un élément de frottement (6) pour générer une force de frottement entre lui-même et le premier élément d'arbre (3) est disposé de façon à être directement ou indirectement en contact avec le premier élément d'arbre (3). Un élément élastique (7) est disposé sur le côté radialement externe du second élément d'arbre (4). L'élément élastique (7) pousse l'élément de frottement (6) dans la direction dans laquelle il est en contact avec le premier élément d'arbre (3), et ceci stabilise la propulsion du second élément d'arbre (4).
