Abstract
A chuck for use with a power driver may include a plurality of jaws, a body assembly, a nut, a sleeve, and a lock ring. The lock ring may include a lock ring interface configured to, when the lock ring is in an unlocked position, permit rotation of the nut relative to the body assembly in a first rotational direction and also permit rotation of the nut relative to the body assembly in a second rotational direction. The lock ring interface may also be configured to, when in the locked position, prevent rotation of the nut in the second rotational direction and apply an anti-vibration compression force on the sleeve, via a damping member, to increase an engagement force between sleeve and the body assembly to reduce vibration in the chuck when the lock ring is in the locked position.
Claims20
A chuck for use with a power driver having a rotatable drive spindle, the chuck comprising:
- a plurality of jaws;
- a body assembly configured to rotate with the drive spindle, wherein the plurality of jaws are configured to rotate with the body assembly about a center axis of the chuck, wherein the plurality of jaws also move relative to the body assembly in an opening or closing direction;
- a nut operably coupled to the jaws such that rotation of the nut relative to the body assembly moves the jaws relative to the body assembly in the opening or closing direction;
- a sleeve coupled to the nut and the body assembly;
- and
- a lock ring operably coupled to the nut and the sleeve and configured to rotate with the nut, the lock ring comprising a lock ring interface with a damping member, the lock ring interface being configured to:
- when the lock ring is in an unlocked position relative to the sleeve, permit rotation of the nut relative to the body assembly in a first rotational direction to move the jaws in the closing direction and also permit rotation of the nut relative to the body assembly in a second rotational direction to move the jaws in the opening direction, the second rotational direction being opposite the first rotational direction;
- and
- when the lock ring is in the locked position, permit rotation of the nut relative to the body assembly in the first rotational direction to move the jaws in the closing direction, prevent rotation of the nut relative to the body assembly in the second rotational direction, and apply an anti-vibration compression force by the damping member on the sleeve to increase an engagement force between sleeve and the body assembly to reduce vibration in the chuck when the lock ring is in the locked position.
6 more elements
A chuck comprising:
- a body assembly;
- a plurality of jaws, wherein the plurality of jaws rotate with the body assembly about a center axis of the chuck, wherein the plurality of jaws also move relative to the body assembly in an opening or closing direction;
- a nut operably coupled to the jaws such that rotation of the nut relative to the body assembly moves the jaws relative to the body assembly in the opening or closing direction;
- a sleeve;
- and
- a lock ring operably coupled to the nut and the sleeve, the lock ring being coupled to the nut such that the lock ring and the nut rotate together, the lock ring being coupled to the sleeve such that the lock ring rotates relative to the sleeve when transitioning between a locked position and an unlocked position;
- wherein the lock ring comprises a damping member configured to apply an anti-vibration compression force on the sleeve to increase an engagement force between sleeve and the body assembly to reduce vibration in the chuck when the lock ring is in the locked position, wherein the anti-vibration compression force is not applied when the lock ring is in the unlocked position;
- wherein, when the lock ring is in a locked position, rotation of the nut relative to the body assembly to move the jaws in the opening direction is prevented.
5 more elements
A chuck comprising:
- a body assembly;
- a plurality of jaws, wherein the plurality of jaws rotate with the body assembly about a center axis of the chuck, wherein the plurality of jaws also move relative to the body assembly in an opening or closing direction;
- a nut operably coupled to the jaws such that rotation of the nut relative to the body assembly moves the jaws relative to the body assembly in the opening or closing direction;
- a sleeve;
- and
- a lock ring operably coupled to the nut and the sleeve, the lock ring being coupled to the nut such that the lock ring and the nut rotate together, the lock ring being coupled to the sleeve such that the lock ring rotates relative to the sleeve when transitioning between a locked position and an unlocked position;
- wherein the lock ring comprises a ring portion and a damping arm, the ring portion defining a ring portion plane, the damping arm extending from the ring portion at an angle such that an end of the damping arm is out of the ring portion plane;
- wherein the damping arm exhibits a damping mechanical bias and the damping arm is configured to apply an anti-vibration compression force that is directed parallel to the center axis of the chuck, via the damping mechanical bias, on the sleeve to increase an engagement force between internal sleeve and the external sleeve to reduce vibration in the chuck when the lock ring is in the locked position, wherein the anti-vibration compression force is not applied when the lock ring is in the unlocked position;
- wherein, when the lock ring is in a locked position, rotation of the nut relative to the body assembly to move the jaws in the opening direction is prevented.
