Abstract

Cette invention se rapporte à un dispositif d'entraînement utilisant un aimant permanent comprenant une partie de prise de force et une partie d'entraînement. La partie de prise de force comprend un arbre principal non magnétique (4) supporté par des paliers (3). De nombreuses pièces attirées (5) sont fixées en spirale sur la surface de l'arbre principal (4) dans la direction axiale. La partie d'entraînement comprend une courroie (8) et des supports de courroie (9). De nombreux aimants permanents (10) sont fixés sur la surface extérieure de la courroie (8). Dans la plage de fonctionnement, la courroie (8) et l'arbre principal (4) sont axialement parallèles. Il existe un espace entre l'aimant permanent (10) et les pièces attirées (5). La distance entre les aimants permanents adjacents (10) est égale au pas de spirale de la pièce attirée. Le dispositif d'entraînement convertit un mouvement linéaire en un mouvement rotatif en utilisant la force magnétique de l'aimant permanent. Il n'y a pas de frottement mécanique direct au cours de la transmission et cela réduit la pollution sonore.
