摘要： A chuck for a manual or powered driver having a rotatable driveshaft includes a body having a front section and a rear section. A plurality of jaws are operatively associated with the body, and the jaws are adapted to engage a tool to be utilized by the driver. The body's rear section includes serrations extending outwardly therefrom. A sleeve member is pressed onto the serrations whereby the serrations dig into the sleeve to at least assist in rotationally securing the sleeve to the body.

摘要： A non-impact keyless chuck suitable for use with manual or powered drivers is disclosed. The chuck comprises a body which carries a rotatable split nut having a relatively fine thread and a plurality of slidable jaws, which may be identical, driven by the rotatable nut. An anti-friction bearing is disposed between the rotatable nut and a bearing thrust ring mounted on the body. A clutch or torque limiting mechanism is provided to limit the tightening torque to a predetermined value while the loosening torque may be limited or unlimited. The front sleeve, and rear sleeve, if used, may be formed from a structural plastic to reduce manufacturing costs. A relatively soft elastomeric grip boot may be placed on the front sleeve to improve the grip and temporarily restrain and center the tool during chuck tightening or loosening operations. A relatively soft elastomeric grip boot may also be placed on the rear sleeve, if used.
