ABSTRACT:
A power operated chuck comprises a rotatable chuck body having a plurality of clamping jaws which are radially movably mounted on the chuck body. An axially movable piston on the chuck body is moved by a moving mechanism which includes several hooks or hook members having wedge-shaped interengaging surfaces for effecting relative movement therebetween. The chuck body has a plurality of recesses with counterweights which are slidably movable or pivotally movable in the recesses. The cover covers the recess adjacent an end of the chuck body. A pressure member alongside each of the counterweights is laterally offset relative to the center of gravity of the associated counterweights and is mounted in the chuck body for rotary movement in a manner such that the centrifugal forces produced by rotation of the counterweights at the chuck body are applied against the exterior of the piston adjacent the wedge-shaped portion of the hooks.
