Abstract

A power source drives a main input shaft. A plurality of output shafts are located around a bull gear which is coupled to the main input shaft. A number of generators are each coupled to a respective one of the output shafts, such that each one of the output shafts drives a generator. A number of intermediate gears are located around a perimeter of the bull gear, alternating half of the intermediate gears on one side of the bull gear and half on an opposite side of the bull gear. Each one of the intermediate gears is pressure fitted to an intermediate pinion with teeth that engage the bull gear teeth. Each one of the output shafts has two pinions that engage two intermediate gears, one on one side of the bull gear and one on an opposite side of the bull gear.
