    摘要： A power tool that includes a housing, a motor, a planetary transmission, a first bearing and a second bearing. The motor is disposed in the housing and includes an output shaft. The planetary transmission has a sun gear, a plurality of first planet gears, a first ring gear and a carrier. The sun gear is driven by the output shaft. The first planet gears are driven by the sun gear and have teeth that are meshingly engaged to teeth of the first ring gear. The carrier includes a rear carrier plate and a front carrier plate between which the first and second planet gears are received. The rear carrier plate includes a first bearing aperture. The first bearing is received in the first bearing aperture and is configured to support the output shaft. The second bearing is received onto the rear carrier plate to support the carrier relative to the housing.

    摘要： A power driver may include a housing, a tool chuck and a sleeve. The tool chuck may have a chuck body mounted for rotation on the housing and supporting threadless chuck jaws, and a chuck drive shaft mounted for rotation on the chuck body. The sleeve may be mounted on the tool chuck for adjustment into a DRILL DRIVE MODE to rotationally lock together the chuck body and the chuck drive shaft, and a CHUCK MODE to rotationally lock together the chuck body and the housing.

    摘要： A power tool having a rotary impact mechanism and a mode change mechanism. The impact mechanism is driven by an output member of a transmission and includes a hammer and an anvil. The mode change mechanism includes a mode collar that is movable between a first position, in which the mode collar directly couples the hammer to the transmission output member to inhibit movement of the hammer relative to the spindle, and a second position in which the mode collar does not inhibit movement of the hammer relative to the spindle. A power tool having an impact mechanism with an external adjusting member that can be moved to vary a trip torque of the impact mechanism is also provided.

    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, that may be utilized for retaining an outer bearing during driver assembly and during subsequent operation of the power driver. In particular, the disclosed structures provide one or more surfaces, particularly inner peripheral surfaces, that limit the outward axial movement of the bearing. These structures may include combinations of surfaces defined by retaining members including, for example, one or more flanges, clips and threaded members, an input shaft, biasing mechanisms, typically a spring or other resilient structure, and chuck shield assemblies for positioning the outer bearing within the power driver.

    摘要： An improved method is provided for controlling a power tool having a rotary shaft. The method includes: disposing an inertial mass in a housing of the power tool, such that the inertial mass is freely rotatable about an axis of rotation which is axially aligned with the rotary shaft; monitoring rotational motion of the power tool in relation to the inertial mass during operation of the power tool; and activating a protective operation based on the rotational motion of the power tool in relation to the inertial mass.
