Abstract: A drive coupling configured to operate with an electrical power system of a machine is disclosed. The drive coupling includes a planetary gear system including a ring gear configured to receive input from an engine and a sun gear configured to drive a drive shaft of a generator, a plurality of planet gears each arranged on a planet gear shaft, the plurality of planet gears meshing with the sun gear and the ring gear, and a planet carrier includes a first planet carrier deck and a second carrier deck having an open portion therebetween to receive the sun gear and the plurality of planet gears. The drive coupling further includes a bearing arranged in the planet carrier configured to support the drive shaft of the generator.
