Abstract

A drive unit for a power tool has a motor driven output gear rotatable about an output axis, a rotatable carrier plate, and a plurality of idler gears rotatably mounted on pins affixed to the carrier plate such that the gears engage the periphery of the output gear. The unit includes a drive shaft supported at one end by the carrier plate, and a non-rotatable ring gear floatingly mounted for engagement with the idler gears, whereby rotation of the output gear is coupled to the drive shaft, and hence to the tool bit, through the carrier plate and the carrier plate is urged toward rotational alignment with the axis of the output gear through the action of rotational forces.
