<p>A self-gripping chuck has a basic body (1) which is cylindrical at least in certain areas and carries a screwed-in coaxial thrust spindle (8) on which gripping jaws (9) coupled to it in a positive-locking manner are axially supported. The gripping jaws are guided in a jaw support (13) which, together with an annular closure part (14) interacting with the gripping jaws, is connected to a sleeve (18) in such a way as to be fixed in terms of rotation, which sleeve (18) is rotatably mounted on the basic body. A wrap spring clutch with a wrap spring (22) coaxial to the basic body is arranged between the sleeve and the basic body. Relative rotation between the sleeve and the basic body in the release direction of the gripping jaws can be blocked by the wrap spring clutch. …<IMAGE>… </p> |
