Abstract: A power tool that includes a housing, a motor, a pair of motor bearings, a transmission, an output spindle and front and rear spindle bearings. The motor is received in the housing and includes a stator and an output shaft that extends through the stator. The motor bearings support the output shaft for rotation relative to the housing and are disposed on opposite ends of the stator. The transmission is driven by the motor and includes an input pinion that is mounted to the output shaft for rotation therewith. The output spindle is driven by the transmission. The front spindle bearing is mounted to a front end of the output shaft radially between the housing and the output shaft. The rear spindle bearing is mounted to a rear end of the output spindle and a portion of the rear spindle bearing rotates with the output shaft.

Abstract: A power tool with a housing, a motor, a transmission, a spindle and an impact mechanism. The motor has an output shaft that drives the transmission. The transmission has a plurality of planet gears, a planet carrier journally supporting the planet gears for rotation about an axis, and a ring gear that is in meshing engagement with the planet gears. The impact mechanism has a plurality of anvil lugs, an impactor and an impactor spring. The anvil lugs are coupled to the ring gear and are not engaged by the planet gears. The impactor is mounted to pivot about the spindle and has a plurality of hammer lugs. The impactor spring biases the impactor toward the ring gear to cause the hammer lugs to engage the anvil lugs. 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.

Abstract: A power tool with a motor, a housing, a transmission, an output spindle, a front bearing and a rear bearing. The motor has an output shaft. The transmission is disposed in the housing and receives a rotary input from the output shaft. The transmission includes an input planetary stage, which has an input planet carrier, and an output planetary stage. The output spindle is driven by the transmission and has a first end, which extends at least partly through the input planetary stage, and a second end opposite the first end. The front bearing is disposed between the output spindle and the housing to support the second end of the output spindle for rotation about the spindle axis. The rear bearing indirectly supports the first end of the output spindle in the housing for rotation about the spindle axis.
