ABSTRACT:
An injection unit for an injection molding machine includes a screw cylinder, a plasticizing screw which can be driven therein axially and rotatably, the drive unit of which has an electric drive motor, a spindle drive coupled to the screw for the axial movement of the screw, and a rotary drive arranged coaxially with the spindle drive and allowing an axial displacement of the screw for the rotational movement of the screw. A differential gearing, is arranged between the drive motor, on the one hand, and spindle drive and rotary drive, on the other hand, with a differential cage, two driven gears and at least one compensating gear in between.
