Abstract
A gear train assembly which includes a ring gear, a drive gear and at least one planetary gear which revolves about the drive gear within the ring gear. The gear train assembly also includes a universal carrier having a plurality of mechanical interfaces disposed thereon which anchor one end of a stanchion and a universal carrier cover having a complimentary plurality of mechanical interfaces which anchor the other end of the stanchion. A pivot assembly with a bushing mounts the planetary gear to a swing arm which is coupled to the stanchion. The gear ratio of the gear train can be selectively manipulated simply by changing the size and location of the gears which, in turn, alters the number of stanchions and the size and location of the pivot assemblies. In this manner, the same carrier and carrier cover plate can be used with multiple gear ratios.
