<p>In this device, the movement-converting system (3) is arranged on a rotationally drivable work spindle (1) of a machine tool in such a way as to rotate with the work spindle (1) and is to be actuated by a servo-motor (4) arranged in a stationary position. It has two regulating gears (61, 62) which are rotatable on the work spindle (1) and are to be rotated relative to one another in opposite directions of rotation for actuating the movement-converting system (3). Revolving differential gearing (7) is arranged between the regulating gears (61, 62) and the servo-motor (4). The rotary movement introduced by the servo-motor (4) via a drive member (8) is transmitted in the differential gearing (7) via two output gears (91, 92). The output gears (91, 92) are each connected in a rotary manner to one of the regulating gears (61, 62), reversal of the direction of rotation being effected between the output gear (91) and the corresponding regulating gear (61). The rotation of the regulating gears (61, 62) is converted into axial adjustments of the regulating bar (2) via threaded clamping spindles (501, 502). …<IMAGE>… </p> |
