    摘要： A power tool that includes a housing assembly, a motor received in the housing assembly, a trigger, an output spindle, a transmission and a bearing. The transmission is received in the housing assembly and transmits rotary power between the motor and the output spindle. The transmission has an output planetary stage with an output planet carrier. The transmission also has a member that is axially movable between a first position, which causes the transmission to operate in a first speed ratio, and a second position in which the transmission operates in a second speed ratio that is different than the first speed ratio. The bearing is disposed radially between and engages both the housing assembly and the output planet carrier. The output spindle is at least partially received into the output planet carrier such that the bearing indirectly supports the output spindle.

    摘要： A power tool includes a housing, a motor contained in the housing, an output shaft extending proximate a front of the housing, an end effector coupled to the output shaft and configured to hold an accessory; and a transmission disposed in the housing between the motor and the output shaft. The transmission includes a variable ratio gear set configured to transmit power from the motor to the output shaft at a substantially variable speed ratio. The transmission may further include a constant ratio gear set configured to transmit power from the motor at a substantially constant speed ratio. The transmission may be automatically or manually shiftable between a first mode where it transmits power through the constant speed ratio gear set and a second mode where it transmits power through the variable speed ratio gear set.

    摘要： A vibration dampening handle for a powered apparatus includes an elongate gripping member including a first end, a second end opposite the first end, a longitudinal axis extending through the first end and the second end, and a wall defining a bore having an inner surface. The bore extends along the longitudinal axis at least partially through the gripping member, and opens on the first end of the gripping member. A mass is disposed at the second end of the gripping member. An elastic beam is attached to or integral with the gripping member. The beam extends along the longitudinal axis and a portion of the beam is disposed within the bore and is spaced apart from the inner surface. The beam includes a first end that extends beyond the first end of the gripping member and includes a fastening member adapted to connect the handle to the powered apparatus.
