Abstract
A four-jaw self-centering chuck comprises a housing (1,12) having mounted therein radially movable clamping jaws (3,14) cooperating with a self-centering mechanism operatively connected with a drive for imparting radial motion to the jaws (3,14). The self-centering mechanism includes four levers (6, 25) having their pivot axles (7, 24) carried by a member of the drives. The clamping jaws (3, 14) are adapted to receive therein the ends of the adjacent levers (6, 25) forming a closed force circuit (11, 28).
