The invention relates to a shaft and hub connection (20) for transmitting torque, a common longitudinal axis (X-X) comprising the following components: a shaft (22) which rotates about the longitudinal axis (X-X) and comprises an entraining longitudinal section having an untrue outer contour (26), and a hub (24) that is coaxial to the shaft (22) and encloses the shaft (22) with its internal contour (28) at least in the area of the entraining longitudinal section. The invention is characterized in that the outer contour (26) of the entraining longitudinal section of the shaft (22) and the inner contour (28) of the hub (24) have the shape of a perfect cone to such a degree that, when the shaft (22) and the hub (24) are assembled, they automatically self-lock, thereby holding the shaft and hub connection (20) together. The connection also comprises connecting means which prestress the shaft (22) and the hub (24), when assembled, in the direction of the longitudinal axis (X-X).
L'invention concerne un assemblage arbre-moyeu (20) destiné à la transmission d'un couple et comportant les composants suivants ayant un axe longitudinal (X-X) commun: un arbre (22) tournant autour de l'axe longitudinal (X-X) et ayant une section longitudinale d'entraînement au contour externe (26) ovale et un moyeu (24) qui est coaxial à l'arbre (22) et qui, au moins dans la zone de la section longitudinale d'entraînement, entoure l'arbre (22) de son contour interne (28). L'invention est caractérisée en que le contour externe (26) de la section longitudinale d'entraînement de l'arbre (22) et le contour interne (28) du moyeu (24) ont une forme de cône réel telle que lorsque l'arbre (22) et le moyeu (24) sont assemblés, ils règlent un auto-blocage qui maintient l'assemblage arbre-moyeu (20), et en ce qu'un élément de liaison serre l'arbre (22) et le moyeu (24) dans la direction longitudinale (X-X) en mode assemblé.
