Abstract
Abstract An improved gear system of greater efficiency having less bearing loading and less power requirement to rotate long gear trains. The system includes a plurality of large power gears serially mounted which receive rotative force from another power gear, the power gears positioned to turn respective power gear shafts. The power gear shaft transmits rotative forces to a drive gear which is smaller in diameter with respect to the power gear which drives it. The drive gear powers an individual satellite gear system of driven gears which drive a plurality of work producing satellite shafts. The large power gear in turn drive a downwardly positioned, similar, large power gear which in turn powers its own satellite gear train. In this manner the load of rotating the work producing shafts into a plurality of individual systems is broken up.
