Abstract

An impact power tool includes one or more of the following features including a housing, a motor, an output spindle, a rotary impact assembly, and a planetary transmission having a fixed ring gear and rotatable planet gear carrier. In an aspect, the planetary transmission is configured to transmit rotational motion from a motor output shaft to a cam shaft at a single overall speed reduction ratio. The planetary transmission includes a sun gear rotatably driven by the motor output shaft, a planet carrier rotatably driving the cam shaft, a ring gear rotationally fixed relative to the tool housing, a first planet gear mounted to the planet carrier and meshed with the sun gear but not meshed with the ring gear and a second planet gear mounted to the carrier and meshed with the ring gear but not meshed with the sun gear.
