Abstract
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.
