Abstract

L'invention concerne un système de transmission à volant d'inertie destiné à un appareil d'exercice/réadaptation. Un arbre principal (201) auquel est appliqué le couple, est relié à un volant d'inertie (204) tournant autour de l'axe de l'arbre principal (201) et l'entraîne par l'intermédiaire d'un mécanisme d'engrenage. Ce système sert essentiellement à apporter une solution aux problèmes techniques posés par le système de transmission à volant d'inertie des vélos d'exercice de l'état de la technique, qui présentent une structure complexe, occupent un espace important et présentent des risques de glissement, de défaut d'alignement et de chute de la courroie d'entraînement. Ce système permet d'améliorer l'efficacité de la main-d'oeuvre lors de la fabrication, de réduire les coûts de production et le taux de rebut. Parallèlement, ce système est compact et occupe moins d'espace.
