Inverted rotaion.

[IJC]

Good day,
First I must apologyse for I am not sure that I may be able to properly get my point across.
I am working on a power generation project. The shaft of a generator has to turn a certain direction, however, the problem is that the "driver" shaft spins half a turn in one direction and 180* in the other, on and on. The generator is 12VDC so it will never see much stres. In other words, take two cylinders, one needs to spin in one direction only (generator) and the driving cylinder will alternate rotation constantly. Is there such a gear out there for this type of aplication?
Any help would be most apreciated.
Thanks in advance.

I guess I should add, pretty much a racheting action system without the clicks. Or would this pretty much the the only way to go about it?

The 'generator' in modern automobiles is really an alteranator. From an electrical perspective, it doesn't care in which direction its shaft rotates. HOWEVER, its cooling fan _does_ care about the shaft rotation.

So, if you could drive your cooling fan in just one direction, e.g. with an electric motor, you could use an alternator for power generation, and do away with the mechanical complexity of a ratcheting drive.

It may not be accurate to say that the generator/alternator will not see much stress because of the low voltage. Low voltage implies large wires, possibly subject to fatigue under constant acceleration and deceleration. It's something you need to check.

Thank you very much Mike, I think I over-thought about this and tried to make things far more complicated than they need to be.
