| 摘要 |
The invention relates to a combination drive for a plastic injection-molding machine having a rotary drive (1) for driving a screw shaft (9) so as to rotate and a linear drive (2) for driving the screw shaft (9) so as to perform a linear movement in the axial direction in relation to the rotary drive (1). When the linear drive (2) performs a linear movement, the rotary drive (1) is linearly entrained, thereby avoiding any axial forces on the rotary drive (1).
