Disc driven chuck

摘要

A chuck for use with a power driver includes a generally cylindrical body 20, a plurality of jaws and a driving disk 60 axially moveably disposed about the body in driving engagement with the jaws so that axial movement of the driving disk with respect to the body moves the jaws toward or away from the chuck body axis. The driving disk defines a threaded outer circumferential surface that engages a threaded inner circumferential surface 58 of a generally cylindrical sleeve so that relative rotation between the sleeve and driving disk axially moves the driving disk with respect to the body. The driving disk defines a plurality of cylindrical slots 106 extending at least partially radially therethrough. Each jaw includes a portion 68 thereof that is shaped cooperatively with respect to the cylindrical slot and that is received thereby so that the jaw is axially fixed, and radially slidable with respect to the driving disk.
