A planetary gear assembly including:
- a sun gear defining a first axis of rotation;
- planetary gears engaging the sun gear;
- a ring gear arranged about the planetary gears, the ring gear engaging the planetary gears;
- and
- a carrier frame including one or more pairs of bearing containment bands, a plurality of connecting segments, a plurality of spoke portions, and a hub portion, wherein each pair of bearing containment bands is connected to an adjacent pair of bearing containment bands with a connecting segment of the plurality of connecting segments and a spoke portion of the plurality of spoke portions connects each connecting segment to the hub portion, wherein the carrier frame defines a second axis of rotation, wherein the spoke portion intersects the hub portion and defines an oblique angle defined by a portion of the spoke portion and the second axis of rotation.
