Abstract

a. Accouplement par emboîtement dans lequel les deux éléments de l'accouplement portent respectivement une partie mâle et une partie femelle s emboîtant l'une dans l'autre. b. La partie femelle est constituée par un évidement central pourvu de plusieurs entailles périphériques comprenant chacune une face d'appui parallèle à un plan passant par l'axe d'accouplement, afin de transmettre un couple élevé dans un sens de rotation déterminé, et une face dite d'éjection, inclinée par rapport à ce plan et divergeant vers l'extérieur, permettant seulement de transmettre un couple relativement faible dans l'autre sens. c. Vis indévissables.
