Abstract

L'invention concerne un accouplement pour mécanisme de transmission. Il est placé entre des pièces rotatives 105 et 106 qui sont en relation d'entraînement par l'intermédiaire de dents 194 en prise axiale et qui peuvent être séparées par un ressort 197, une des pièces ayant deux éléments 190 et 193 couplés par des cannelures hélicoïdales 192, dont l'un, 193, est monté sur un élément fusible 200. La fusion de l'élément 200 en cas d'élévation excessive de la température permet le déplacement axial des éléments 190 et 193 grâce aux cannelures 192, si bien que les dents 194 sont séparées et qu'il se produit un effet de rochet entre les pièces 105 et 106. L'invention s'applique à des mécanismes de transmission à vitesse très élevée, notamment à des mécanismes fournissant une vitesse constante à un alternateur d'avion.
