  • Tool chuck for a turning machine such as a drill
    Patent number: 5186478
    Abstract: A chuck includes a body mounted on the motor shaft of a machine. A plurality of jaws is mounted to slide in bores and converge forward. A sleeve surrounds the body and is mounted to pivot around the latter. The jaws have an outer threaded part which meshes with a nut surrounding the jaws and integral with the sleeve surrounding the body. A series of balls is interposed between the face of the nut which faces rearward and the body of the chuck. The balls abut a ring made of a hard material, and that ring in turn abuts a ring made of synthetic material which exhibits shock-absorbent characteristics and is locked against the body.
