Abstract: A carrier for a planetary gear train includes a hub disposed about an axis of rotation, the hub having an external cylindrical surface including a plurality of splines extending along a longitudinal direction, the longitudinal direction being parallel to the axis of rotation; and a deck extending away from the hub along a radial direction, the radial direction being transverse to the longitudinal direction. The deck defining a plurality of holes therethrough, each hole of the plurality of holes being configured to receive an axle of a planet gear of the plurality of planet gears, the hub being disposed between the plurality of holes and the axis of rotation along the radial direction. The splines have a value of a parameter (P) that is not less than 2.5 and not greater than 6.0.
