摘要： A planetary wheel drive uses a single wall output planet carrier includes an internal spline fixed against rotation through an interconnection with an external spline of the stationary spindle. A locking lug of the single wall output planet carrier extends into a notch of a bearing nut. The locking lug prevents the bearing nut from unthreading itself from the stationary spindle. An output planet thrust plate is bolted to an output planet pin.

摘要： A planetary wheel drive uses a thrust washer residing between a cover and a thrust plate to absorb axial loads. The thrust washer is has a slip fit to the cover. The surface area of the thrust washer engaging the cover is larger than the surface area of the thrust washer engaging the thrust washer.

摘要： A compact planetary wheel drive uses a high speed input planet carrier partially residing with a stationary spindle, and, an input planet gear engaging an internal ring gear within the stationary spindle. Inclusion of the input planet gear within the stationary spindle enables use of an additional stage of the planetary wheel drive while keeping the planetary wheel compact. Two and three stage planetaries may be accommodated with use of the same internal output ring gear of the rotatable output housing.
