Abstract
A two-piece planet carrier for use in a power hand tool, the carrier comprising a drive portion mountable to a rotor of the tool and a pinned portion having a crank pin. The crank pin operatively connectable to a drive shaft of the tool to provide rotation and torque to the drive shaft. The pinned portion rotatably engaged with the drive portion such that rotation of the rotor will cause the drive portion and the pinned portion to rotate relative to each other as a function of a load applied to the drive shaft such that an offset between a crank pin center axis and a drive portion axis of rotation is variable as a function of the load, wherein the variance of the offset will vary a rotational speed and an amount of torque delivered to the drive shaft as a function of the load.
