Abstract
Abstract An apparatus for transmitting torque from a prime mover to a load includes an input planetary gear unit adapted to be connected drivingly to the output of the prime mover, and an output planetary gear unit coupled to the input unit and adapted to be connected drivingly to the input of the load. A reaction member connects rigidly the output planet gears of the output planetary gear unit and one of the input sun gears of the input unit for causing the input planetary gears of the input unit to orbit about the input planet gears, whereby the input unit serves to unload the prime mover to enable it to operate more efficiently.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
115 words
An apparatus for transmitting torque from a prime mover to a load, comprising: an input planetary gear unit adapted to be connected drivingly to the output of the prime mover, said input unit including a plurality of input sun gears and a plurality of input planet gears; an output planetary gear unit coupled to said input unit and adapted to be connected drivingly to the input of the load, said output unit including a plurality of output sun gears and a plurality of output planet gears; and reaction means connecting rigidly said output planet gears and one of said input sun gears for causing said input planet gears to orbit about said input sun gears.
Claim 2
Independent Claim
115 words
An apparatus for transmitting torque from a prime mover to a load, comprising: an input planetary gear unit adapted to be connected drivingly to the output of the prime mover, said input unit including a plurality of input sun gears and a plurality of input planet gears; an output planetary gear unit coupled to said input unit and adapted to be connected drivingly to the input of the load, said output unit including a plurality of output sun gears and a plurality of output planet gears; and reaction means connecting rigidly said output planet gears and one of said input sun gears for causing said input planet gears to orbit about said input sun gears.
Claim 3
Dependent Claim
39 words
An apparatus according to claim 1, wherein at least some of said input planet gears mesh with one another and extend along an input pitch circle in a given direction of reaction from the load via said output unit.
Claim 4
Dependent Claim
89 words
An apparatus according to claim 2, wherein at least some of said output planet gears mesh with one another and extending along an output pitch circle in a direction of reaction from the load opposite from said given direction, said input pitch circle having substantially the same diameter as the diameter of said output pitch circle, said at least some of said output planet gears extending substantially further along said output pitch circle than said at least some of said input planet gears extend along said input pitch circle.
Claim 5
Dependent Claim
39 words
An apparatus according to claim 1, a small one of said gears of said input unit meshes with a larger one of said gears of said output unit to couple torque between said input unit and said output unit.
Claim 6
Dependent Claim
53 words
An apparatus according to claim 1, wherein one of said input sun gears of said input unit is connected fixedly to the output of the prime mover and meshes with one of the input planet gears, another one of said input sun gears of said input unit being fixed to said reaction means.
Claim 7
Dependent Claim
14 words
An apparatus according to claim 1, wherein said reaction means comprises a cylindrical housing.
Claim 8
Dependent Claim
59 words
An apparatus according to claim 1, wherein one of said input sun gears is adapted to be connected fixedly to the output of the prime mover, one of said output sun gears being adapted to be connected to the input of the load, the last-mentioned input sun gear being substantially smaller in diameter than the last-mentioned output sun gear.
Claim 9
Dependent Claim
39 words
An apparatus according to claim 7, wherein at least some of said input planet gears mesh with one another and extending along an input pitch circle in a given direction of reaction from the load via said output unit.
Claim 10
Dependent Claim
