Abstract
A trans-planetary mechanical torque impeller utilizes at least two sets of input planetary pinion gears of differing sizes, which are supported by a planetary carrier. These input planetary pinion gears rotate with respect to primary and secondary annulus gears which, in turn, drive bevel gears which engage a differential pinion gear to drive an output shaft. The output shaft load causes the torque impeller to automatically vary its gear ratio to match the input shaft or motor power output capability to the output shaft load.
Claims4
A trans-planetary torque impeller capable of infinitely responding to changing load conditions while providing specific low input shaft to output shaft ratios at start-up, said torque impeller comprising:
- a rotatable input shaft;
- a planetary carrier supported on and rotatable with said input shaft;
- at least two sets of joined input planetary pinion gears rotatably supported by said planetary carrier, a primary planetary pinion gear in each of said sets of joined input planetary pinion gears being larger in circumference than an adjoining secondary planetary pinion gear;
- a primary annulus gear supported on, and rotatable with respect to said input shaft, and a secondary annulus gear supported by an extension of said input shaft with said at least two sets of joined input planetary pinion gears revolving in unison with each other, said primary and said secondary planetary pinion gears meshing with and planetarily revolving within said primary and said secondary annulus gears;
- an output shaft rotatably supported in said mechanical torque impeller;
- a primary beveled ring gear rotatably driven by one of said primary and said secondary annulus gears, and being in meshing engagement with differential pinion gears housed in a differential drive carrier, said differential pinion gears being in meshing engagement with an output shaft beveled ring gear which is splined to said output shaft, the other of said primary and said secondary annulus gears being splined to said differential drive carrier to constitute the main driving force for said differential pinion gears, said output shaft beveled ring gear being driven by said differential pinion gears, wherein for each revolution of said input shaft and said at least two sets of planetary pinion gears at start-up, said circumferential difference between said primary planetary pinion gears and said secondary planetary pinion gears is applied to said primary annulus gear and to said secondary annulus gear which together drive said differential pinion gears an equal circumferential distance to thereby affect a rotation of said output shaft which is slower than said input shaft rotation at start-up and under load conditions, and to infinitely and continually seek a 1 to 1 ratio between said input shaft and said output shaft as said input shaft speed increases, and as the load on said output shaft decreases.
