Abstract
A gearbox is described that includes a magnetic gear irrotationally mounted on one shaft and a set of gears on another shaft, wherein the one gear is in sequential magnetic interaction with the set of gears to alter to rotational speed of either the one gear or the set of gears.
Claims13
A gearbox for magnetic gears, said gearbox comprising:
- a first shaft having a longitudinal axis;
- a first magnetic gear shiftable along said first shaft, said first magnetic gear being irrotational on said first shaft;
- a second shaft having a longitudinal axis, said first shaft and said second shaft being coplanar and non-parallel;
- a set of magnetic gears mounted on said second shaft, said set of magnetic gears being irrotatable on said second shaft and not being shiftable along said second shaft, and wherein said set of magnetic gears on said second shaft have respective peripheries, said respective peripheries of said set of magnetic gears on said second shaft are enveloped within a conical surface of rotation, and said respective peripheries are in sequence generally tangent and in magnetic interaction with the periphery of said first magnetic gear on said first shaft;
- said first magnetic gear being shiftable along said first shaft to be in sequential magnetic interaction with said set of magnetic gears on said second shaft, wherein one of said first magnetic gear and said set of magnetic gears being initially rotatable at a rotational speed, and effecting the sequential increasing or decreasing rotational speed of adjacent magnetic gears of said set of magnetic gears on said second shaft as said first magnetic gear is shifted along said first shaft and being in sequential magnetic interaction with said respective magnetic gears in said set of magnetic gears on said second shaft.
