Abstract

Powertrains for high torque, low RPM wind turbines and ocean current turbines.
The turbine consists of a large, input power shaft-mounted, rotating sun-gear with stationary powertrains mounted around its periphery. The gear teeth on the sun gear rotate past the teeth on the pinions, causing the pinions to turn and delivering power to each smaller powertrain. Alternatively, the powertrains are attached in a spindle around the perimeter of a main power input drive shaft, and rotate as the shaft rotates. Each input drive shaft to smaller powertrain gearboxes is fitted with a pinion. As the main power input shaft turns, the generators, gearboxes and pinions rotate, moving the pinions around the interior of a stationary ring gear. Reduction and distribution of torque is similar to the sun-gear embodiment of the powertrain. In the sun-gear configuration, each smaller powertrain is stationary, reducing stress caused by rotation.
