Abstract:
1. A system for transferring torque between a pair of independently, concurrently rotating shafts of an engine, the system comprising: a magnetic gearbox, the magnetic gearbox including a first ring structure, a second ring structure and an intermediate ring structure, each of the first, second and intermediate ring structure having an annular aperture therethrough and a plurality of magnetic pole pieces embedded therein, the intermediate ring structure disposed between the first ring structure and the second ring structure, each of the first, second and intermediate ring structure being coaxially disposed, concentric with, and independently rotatable with respect to the remaining ring structures; the first and second ring structures each being coupled to separate ones of the rotating engine shafts, and the intermediate ring structure cooperates with the first ring structure and second ring structure and determines the level of torque transferred between the pair of shafts.
