Abstract
A chuck for use with a power driver having a rotatable drive spindle is provided. The chuck may comprise a plurality of jaws, a front body, a nut, a rear body, and a clutch. The clutch may be configured to move between a working position and a jaw actuating position. In the working position, the clutch teeth may be engaged with the rear body teeth such that rotation of the rear body by the drive spindle rotates the clutch, the front body, and the jaws. In the jaw actuating position, the clutch teeth may not or need not be engaged with the rear body teeth and the rear body may be configured to rotate the nut relative to the front body to move the jaws relative to the front body.
Claims19
A chuck for use with a power driver having a rotatable drive spindle, the chuck comprising:
- a plurality of jaws, each jaw including jaw teeth;
- a front body, wherein the plurality of jaws are configured to rotate with the front body about a center axis of the chuck, wherein the plurality of jaws are also configured to move relative to the front body in an opening or closing direction;
- a nut operably coupled with at least some of the jaw teeth of the jaws such that rotation of the nut relative to the front body moves the jaws relative to the front body;
- a rear body configured to rotate with a drive spindle of the power driver;
- and
- a clutch operably coupled to the front body such that the clutch rotates with the front body in at least one of a working position and a jaw actuating position, wherein the clutch is configured to move between the working position and the jaw actuating position;
- wherein, in the working position, the clutch and rear body are configured such that rotation of the drive spindle rotates the front body and the jaws, and
- wherein, in the jaw actuating position, the clutch and the rear body are configured such that rotation of the drive spindle rotates the nut relative to the front body to move the jaws relative to the front body;
- wherein the chuck further comprises an intermediate gear, wherein, in at least one of the working position and the jaw actuating position, rotation of the rear body causes rotation of the intermediate gear, and the intermediate gear is configured to operably couple the rear body to turn the nut.
