Gear reduction assembly and winch including gear reduction assembly

摘要

A gear reduction assembly may include a main input shaft, a carrier coupled to the main input shaft, and at least one carrier shaft coupled to the carrier and spaced from the main input shaft. The gear reduction assembly may also include at least one spur gear pair including a first spur gear coupled to the carrier shaft, and a second spur gear, wherein the first and second spur gears are coupled to one another such that they rotate together. The gear reduction assembly also includes a first internal gear engaged with the first spur gear, a second internal gear engaged with the second spur gear, and a hub associated with the first internal gear. The first internal gear has a first number of teeth, the second internal gear has a second number of teeth, and the first and second numbers of teeth differ by from one to five teeth.
