Abstract
A power driver may include a housing, a tool chuck and a power take off mechanism. The tool chuck may have an input shaft mounted for rotation on the housing. The input shaft may support chuck jaws. A chuck actuating shaft may be mounted for rotation on the input shaft. The power take off mechanism may be connected to the tool chuck. The power take off mechanism may be adjustable into a DRILL/DRIVE MODE to rotationally drive the input shaft and the chuck actuating shaft together as a unit. Here, a brake may resist relative rotation between the input shaft and the chuck actuating shaft. The power take off mechanism may be adjustable into a CHUCK MODE in which a gear mounted on the input shaft may rotationally drive the chuck actuating shaft relative to the input shaft. Here, the brake may be deactivated.
Claims19
A power driver comprising:
- a housing;
- a tool chuck having
- an input shaft mounted for rotation on the housing and supporting chuck jaws, and
- a chuck actuating shaft mounted for rotation on the input shaft;
- a gear mounted on the input shaft, such that the input shaft is internal of the gear;
- and
- a power take off mechanism connected to the tool chuck, the power take off mechanism being adjustable into
- a DRILL/DRIVE MODE so that the input shaft and the chuck actuating shaft are rotatable together as a unit, and
- a CHUCK MODE to use the gear to rotationally drive the chuck actuating shaft relative to the input shaft.
A power driver comprising:
- a housing;
- a tool chuck having
- an input shaft mounted for rotation on the housing and supporting chuck jaws, and
- a chuck actuating shaft mounted for rotation on the input shaft;
- a gear mounted on the input shaft;
- and
- a power take off mechanism connected to the tool chuck, the power take off mechanism being adjustable into
- a DRILL/DRIVE MODE so that the input shaft and the chuck actuating shaft are rotatable together as a unit, and
- a CHUCK MODE to use the gear to rotationally drive the chuck actuating shaft relative to the input shaft:
- wherein the gear is rotationally coupled to the chuck actuating shaft via a clutch when the power take off mechanism is in the CHUCK MODE.
