Abstract: A final drive assembly for a machine includes an input shaft drivably coupled to a prime mover. The input shaft is coupled to and drives a first stage gear assembly. The first stage gear assembly further drives a second stage gear assembly. The first and second stage gear assemblies drive a ring gear which is coupled to a wheel of the machine. The first and second stage gear assemblies are disposed between a first bearing assembly and a second bearing assembly. A spring member preloads the first bearing assembly to limit an axial movement of the first and second stage gear assemblies.

Abstract: A floating spacer assembly for a gear mounted on a shaft, such as a planet gear mounted to a planet carrier, is disclosed. The gear may be mounted on the shaft with a pair of roller bearings with inner races and bearing rollers, and a gear bore having a gear groove defined therein functioning as the outer races of the roller bearings. The floating spacer assembly may include an annular spacer ring having one or more sector slots circumferentially spaced around the spacer ring, and a spacer sector disposed within each of the sector slots and extending radially outward from the spacer ring and into the gear groove when the floating spacer assembly is installed between the roller bearings. The spacer sectors may engage surfaces of the gear groove and the spacer ring may engage the bearing rollers to limit axial movement of the gear relative to the shaft.

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.
