ABSTRACT:
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).
