Chuck

摘要

Chuck with a chuck body as well as chuck jaws radially movable relative to the chuck body. Each of the chuck jaws consists of a basic jaw and an interchangeable auxiliary jaw, and a centrifugal weight radially movable relative to the chuck body is allocated to each chuck jaw to compensate for the different centrifugal forces acting on various auxiliary jaws, and this centrifugal weight, via a double-arm lever pivotable with respect to the chuck body and having a variable lever-arm length ratio, is in operative connection with this chuck jaw in such a way that a movement of the centrifugal weight radially outwards corresponds to a movement of the chuck jaw to the inside.
