Abstract

Accouplement glissant comprenant: un arbre d'accouplement (26) entraîné en rotation par une source motrice, une paire de pignons glissants (29, 30) portés par l'arbre d'accouplement (26) de manière à pourvoir tourner autour de celui-ci, une paire d'éléments glissants (32, 33) portés par l'arbre d'accouplement (26) de manière à pourvoir tourner à l'unisson avec l'arbre d'accouplement (26) et mobiles dans la direction axiale de l'arbre d'accouplement (26) et de manière à réaliser un contact à friction avec les pignons glissants (29, 30) au droit du côté intérieur de chacun de ceux-ci, un ressort hélicoïdal de compression (36) interposé entre les éléments glissants (32, 33) et amenant ces éléments glissants (32, 33) en contact à friction avec les pignons glissants (29, 30), et un arbre de sortie (17) entraîné en rotation par l'un de la paire de pignons glissants (29, 30).
