<p>The invention describes an actuator having a drive (1) for a shaft (2), on which two belts or ropes can be wound and unwound in a double helical winding pattern. The belts or ropes are in each case guided by a first (7) and second (9) deflection unit and drive the at least one disk-like actuator unit (8, 8'). The displaceability of the position of the deflection units (7, 9) (or the drive, see fig. 2), affects a constant winding angle (a).</p> |
