Distributed powertrain that increases electric power generator density

An electric power-generating device that converts a source of energy to electricity comprising:

• A main input shaft coupled to said source of energy;
• A two-stage torque-dividing gearbox coupled to said main input shaft;
• Said two-stage torque-dividing gearbox having a plurality of output shafts located around said main input shaft;
• A plurality of generators, each connected to a respective one of said torque-dividing gearbox output shafts;
• A first stage of said two-stage torque-dividing gearbox being a circular gear coupled to said main input shaft;
• and,
• A second stage of said two-stage torque-dividing gearbox being two intermediate gears, adjacent intermediate gears being on opposite sides of said circular gear and each driven by a respective intermediate shaft that engages said circular gear;
• Each one of said torque-dividing gearbox output shafts being driven by two adjacent intermediate gears.

An electric power-generating device that converts fluid flow of wind or water to electricity comprising:

• A rotor having blades that rotate in response to fluid flow;
• A main input shaft coupled to said rotor;
• A circular gear having gear teeth around a perimeter of said circular gear, said circular gear being coupled to said main input shaft;
• A number of intermediate gears arranged around said circular gear, adjacent intermediate gears being on opposite sides of said circular gear, each one of said intermediate gears being connected to an intermediate pinion that engages said gear teeth on said circular gear;
• A number of high-speed output pinions, each high-speed output pinion engaging two adjacent intermediate gears;
• and,
• A number of power generators, each one of said power generators coupled to one of said high-speed output pinions.
