    摘要: A control system is provided for use in a power tool. The control system includes: a rotational rate sensor having a resonating mass and a controller electrically connected to the rotational rate sensor. The rotational rate sensor detects lateral displacement of the resonating mass and generates a signal indicative of the detected lateral displacement, such that the lateral displacement is directly proportional to a rotational speed at which the power tool rotates about an axis of the rotary shaft. Based on the generated signal, the controller initiates a protective operation to avoid further undesirable rotation of the power tool. The control scheme employed by the power tool may initiate different protective operations for different tool conditions.

    摘要: 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, and a CHUCK MODE to rotationally drive the chuck actuating shaft relative to the input shaft. The power take off mechanism may be internal of the housing. The power take off mechanism in the CHUCK MODE may rotationally fix the input shaft to the housing.

    摘要: A power driver may include a motor that rotates upon receiving an input current. A tool chuck may have chuck jaws to hold an accessory. The tool chuck may be coupled to the motor. A power take off mechanism may be connected between the motor and the tool chuck. The power take off mechanism may be adjustable into a CHUCK MODE to one of open and close the chuck jaws while the motor rotates. An electronic clutch may interrupt the input current to the motor if the power take off mechanism is in the CHUCK MODE and if the input current exceeds a trip value.

    摘要: Provided are various embodiments of structures that may utilized in a power driver, particularly in a power driver having an optional reciprocating “hammer” action, for retaining an outer bearing during assembly and/or operation of the power driver. In particular, the disclosed structures provide one or more surfaces, particularly inner peripheral surfaces, that limit outward axial movement of the bearing along the input shaft. These structures may include combinations of surfaces defined by retaining means, an input shaft, biasing means and chuck shields for positioning the outer bearing within the power driver.
