The invention relates to an extruder device comprising an extruder worm (4) and a worm drive (1,2) comprising a drive motor (1), which is provided with a rotor (8). The rotor (8) is connected to the extruder worm (4) during operation in such a way that the rotor (8) and extruder worm (4) rotate at the same speed during operation. The rotor can be connected to detachable torque- transmitting elements (6, 14, 15) which transmit torque between the rotor (8) and the extruder worm (4) and which can be detached when refitting occurs. The detachable torque-transmitting elements (6, 14, 15) include a torque- transmission point at which torque is transmitted from one bushing (14) to a connecting section which is at least partially encompassed by the bushing (14). The torque-transmission point in an axial direction is located outside the rotor (8).

Dispositif d'extrusion qui comporte une vis (4) d'extrudeuse et une transmission (1, 2) à vis sans fin comportant un moteur d'entraînement (1) pourvu d'un rotor (8). En fonctionnement, le rotor (8) est couplé à la vis (4) d'extrudeuse de manière telle que le rotor (8) et la vis (4) d'extrudeuse tournent à la même vitesse de rotation. Le rotor peut être couplé à des éléments de transmission (6, 14, 15) de couple détachables qui transmettent le couple entre le rotor (8) et la vis (4) d'extrudeuse et qui peuvent être démontés lors de travaux de rééquipement. Les éléments de transmission (6, 14, 15) de couple détachables comportent un point de transmission de couple auquel le couple est transmis d'un manchon (14) à un segment de couplage (6) entouré au moins en partie par le manchon (14). Le point de transmission de couple dans le sens axial se trouve à l'extérieur du rotor (8).
