ABSTRACT:
An extruder device includes an extruder worm and a worm drive that has a drive motor, which is provided with a rotor. The rotor is connected to the extruder worm during operation in such a way that the rotor and extruder worm rotate at the same speed during operation. The rotor can be connected to detachable torque-transmitting elements which transmit torque between the rotor and the extruder worm and which can be detached when refitting occurs. The detachable torque-transmitting elements include a torque-transmission point at which torque is transmitted from a bushing to a connecting section which is at least partially encompassed by the bushing. The torque-transmission point in an axial direction is located outside the rotor.
