Abstract:
1. A drive device for a machine for the plasticization and injection of synthetic material, said drive device comprising: a main drive having a hollow shaft which is rotatable about an axis of rotation; an axially bipartite inner reception region formed by the hollow shaft and having a first part region and a second part region; rotation transmission means, arranged at least partially in the first part region, for transmitting a rotational movement of the hollow shaft solely in a first direction of rotation to an extruder worm which is rotatable about the axis of rotation; and conversion means, arranged at least partially in the second part region, for transmitting a rotational movement of the hollow shaft in the first and a second direction of rotation to a supporting shaft rotatable about the axis of rotation and displaceable axially in the first and second directions, and for converting the transmitted rotational movement into an axial movement of the supporting shaft.
