Abstract
A self-centering chuck for machine tools such as lathes includes jaw members (3) opened and closed by an electric motor (10-11) associated with an epicyclical reducing unit (19-20-21) which acts via a rotating nut (22) and rotationally fixed but axially moving screwsleeve (25) to operate wedge means (6a, 33) and radially move the jaws (3). The clamping force or torque on the workpiece, or bar, is obtained from the torque provided by the locked-rotor motor and is transmitted to the clamping jaws (3) by means of elastic means (27-28-29) disposed between the nut (25) and cylindrical wedge member 32, the value of the clamping force being held constant by means of an electromagnetic brake (14-15-16) acting on the rotor as this latter has achieved the desired clamping torque or by means of mechanical torque limiting means. <IMAGE>
