ABSTRACT:
A power-operated chuck with gripping jaws guided radially in a chuck body, each of the jaws being driven by a spur toothing from a drive jaw which is movable radially inside the chuck body. The drive jaws are driven by a chuck piston which is axially movable in the chuck body and operates all the drive jaws in common. Independently of the corresponding gripping jaw, each drive jaw is guided in the radial direction and guided non-displaceably in the tangential direction and fixed in position in the axial direction directly in the chuck body. As a result there occurs an indirect securing of the positive connection between the clamping jaws and driving jaws, which positive connection is directly provided by the spur toothing. The chuck piston which is guided directly in the chuck body can be moved beyond the working stroke into a position in which it is out of engagement with the drive jaws.
