- How do I transmit power from two shafts, rotating in the opposite directions at different speeds to one shaft perpendicular to both of them?
you mean make the two input shafts rotate in the same direction?Well it's kind of what a car differential does. You'd have to reverse one of the two to get them rotating the same way, but if you can't figure out how to do that, you're in the wrong business.
You have a 'mystery transmission element' in the picture. You mean you're not allowed to put gears or other moving parts inside that? If you are, then what restriction is preventing you from doing so?you mean make the two input shafts rotate in the same direction?
I can't do that, they absolutely have to rotate in the opposite direction heh

Do the two input shafts have to be coaxial? If you can offset them a bit from each other perpendicular to their axes, that would make it simpler.How do I transmit power from two shafts, rotating in the opposite directions at different speeds to one shaft perpendicular to both of them?
yes i can move them anywhere but they have to remain horizontalDo the two input shafts have to be coaxial? If you can offset them a bit from each other perpendicular to their axes, that would make it simpler.
Great. If you offset them you can use fairly simple gears in that transmission, IMO. Offset one shaft up and the other one down and use bevel gears or similar to couple the two input shafts to the output shaft. If the two input shafts need different gear ratios, use seperate bevel gears to do the coupling.yes i can move them anywhere but they have to remain horizontal
Let us assume that the perpendicular output shaft speed must be the sum of the speeds of the two counter-rotating, independent, input shafts.i can put anything in the mystery area

1. Three bevel gears.
2. One reversing gear and a differential.
3. Two hydraulic pumps, in parallel, driving one hydraulic motor.
4. Two DC voltage generators, in series, driving a DC motor.
5. Two shaft encoders, a microcontroller, and a servo or stepper motor to drive the output shaft.
I swear Im not playing dumb2. One reversing gear and a differential.
It is the simplest, but limited solution. The bevel gears would need tooth counts that allowed for a fixed ratio of input shaft speeds.How could 3 bevel gears work here?
One pinion drives a second pinion on a parallel side shaft, called a counter-shaft, which must then counter-rotate.Whats a reversing gear ?
Since the input shafts are counter-rotating, the subtraction would become an addition.How could 3 bevel gears work here?
if one is mounted on each of the shafts and the input shafts both interlock with the output shaft then won't the input shafts just subtract from each other?
