ABSTRACT:
A power-actuated chuck comprises a chuck body in which a plurality of chuck jaws are radially displaceable, each jaw having inclined teeth engageable by a substantially linearly displaceable wedge or camming element on the chuck body. A drive ring is connected to all of these wedge members for the joint displacement thereof and is, in turn, actuated by a tangentially displaceable slider which is shifted by an axially displaceable member connected to an axially effective piston-and-cylinder arrangement.
