Abstract:
A torque transfer assembly adapted for use in a planetary gear train, the gear train including a sun gear rotatable about an axially extending central axis, a concentric outer ring gear, and a plurality of planet gears mechanically intermediate said sun gear and said ring gear and in meshing engagement therewith, the plurality of planet gears adapted for receiving torque input from the sun gear, said torque transfer assembly comprising:a planetary carrier rotatable about said axially extending central axis and adapted to rotatably support said plurality of planet gears on a plurality of axles between first and second axle ends, said first and second axle ends defining first and second planes respectively, said plurality of axles being parallel to the central axis and the first and second planes being perpendicular to the central axis, the planet gears being circumferentially located on the planetary carrier about the central axis, the carrier having a first connecting member extending therefrom; and a torque transfer coupling adapter disposed concentrically with said planetary carrier and rotatable therewith, said torque transfer coupling adapter having a central torque output element and a second connecting member extending therefrom, said second connecting member adapted to be engaged with said first connecting member to structurally join the coupling adapter and the planetary carrier, said first and second connecting members being structurally joined together between said first and second planes.
