ABSTRACT:
An apparatus and method for transmitting a rotary input into counter-rotating outputs is disclosed herein. An exemplary apparatus for performing the method includes a planetary gear set having a sun gear rotatable by a rotary input, a plurality of planet gears in meshed engagement with the sun gear, a carrier coupling the plurality of planet gears together, and a ring gear encircling and in meshed engagement with the plurality of planet gears. The exemplary apparatus also includes a first shaft member coupled to the carrier for transmitting motion in a first rotational direction. The exemplary apparatus also includes a second shaft member coupled to the ring gear for transmitting motion in a second rotational direction opposite the first rotational direction. The first shaft member at least partially encircles the second shaft member.
