Abstract

L'invention se rapporte à un accouplement d'arbres, qui se caractérise en ce qu'un élément de montage (6) côté arbre menant est monté sur la surface circonférentielle externe d'une partie terminale (2) d'un arbre menant, en ce que des éléments coulissants en métal (10a, 10b) côté arbre menant ayant chacun une surface externe coulissante qui est parallèle au plan X-Z sont montés sur l'élément de montage, en ce qu'un élément de montage (8) côté arbre mené est monté sur la surface circonférentielle externe d'une partie terminale (4) d'un arbre mené, en ce que des éléments coulissants en métal (12a, 12b) côté arbre mené ayant chacun une surface externe coulissante qui est parallèle au plan Y-Z sont montés sur l'élément de montage, et en ce qu'on prévoit un élément de transmission de force rotatif en forme de disque (14), qui comporte des trous traversants ayant chacun une surface interne coulissante qui coulisse par rapport à la surface externe coulissante de l'élément coulissant côté arbre menant, et des trous traversants ayant chacun une surface interne coulissante qui coulisse par rapport à la surface externe coulissante de l'élément coulissant côté arbre mené. Cet accouplement d'arbres permet non seulement la réalisation d'un mécanisme d'excentrique, l'existence d'un angle de déflexion et la création d'un mouvement dans une direction de poussée entre l'arbre menant et l'arbre mené, pour qu'une force de rotation puisse être transmise sans à-coups et avec une perte faible, mais également de simplifier la construction, l'assemblage et la maintenance.
