Patent ID: 7296495

Claim:
A mechanical power system, comprising: at least two power disc elements mounted for rotation about a central axis; a first system gear, mounted on a first system shaft which is offset from the central axis, wherein the first power disc element includes a first peripheral gear portion in the vicinity of a rear rim thereof for mating with the first system gear, wherein the first power disc element has a second peripheral gear portion in the vicinity of a forward rim thereof, and wherein the second power disc element has a plurality of outer gear members rotatably mounted to a rear surface thereof and positioned to mate with the second peripheral gear portion on the first power disc element, wherein the second peripheral gear portion on the first power disc element has a diameter which is substantially less than an outside diameter of the first power disc element; a central gear which is mounted so as to be fixed relative to the central axis and which is further mounted to mate with the outer drive gears on the second power disc element, such that rotation of the first system gear results in rotation of the first and then the second power disc element; and a second system gear mating with a forward peripheral gear portion of the second power disc element, located in the vicinity of the rim of the second power disc element, the second system gear mounted on a second system shaft which is offset from the central axis, wherein in operation a power change results between the first and second system shafts in operation of the mechanical power system.
