Abstract

Les systèmes de paliers tels que les paliers magnétiques sont largement utilisés de nos jours. Toutefois, ils sont tous susceptibles d'avoir des défaillances. C'est pourquoi on utilise souvent des systèmes de renfort en combinaison avec un système de paliers principal. Le système de douilles de renfort de la présente demande s'utilise avec un ensemble à volant d'inertie qui est aligné et tourne autour de l'axe d'un arbre fixe et comprend une première douille sensiblement fixe par rapport à l'axe, et qui présente un première partie de contact, et une deuxième douille, espacée par rapport à la première et sensiblement fixe par rapport à l'axe, et qui présente un deuxième partie de contact. Si l'ensemble à volant d'inertie subit un mouvement de décentrage par rapport à l'axe, il entre en contact avec les première et deuxième douilles. A l'entrée en contact, les douilles agissent pour contenir la rotation de l'ensemble à volant d'inertie entre les parties de contact, ce qui maintient sensiblement l'alignement de cet ensemble par rapport à l'axe et empêche le 'flottement'.
