| 摘要 |
The invention relates to a drive device (1) comprising a roll body screw (11, 12). A hollow rotor (6) is mounted inside the roll body screw's housing that, transversal to the rotation axis, is divided into two housing parts (2, 3). An antifriction mounting (12, 25) permits the hollow rotor to rotate. A threaded spindle (20, 28) of the roll body screw (11, 22) is guided through said rotor (6). The threaded spindle (20, 28) is rotationally mounted on a spindle nut (10, 27) of the roll body screw (11, 22), said spindle nut being drive-connected to the rotor (6), and the antifriction mounting (11, 22) is provided on only one housing part (3) of the housing (2). |
