Can you drive the worm using the worm gear? Is the overhauling worm gear used to transmit power?

RE: Gears
Perhaps you need to give the rest of us even the slightest indication of what you are attempting to do.

RE: Gears
Do you want it to act as a speed-reducer, or a speed-increaser?
Worm gears will work as speed reducers (in which input torque is applied to the worm, and output is taken from the mating gear) but they are not good in the opposite direction. Efficiency tends to be poor, even when used in the normal direction.
It would still really help if you gave us some idea of the application. Are you building a watch mechanism, and you need to translate the motion of the finger operated wind-up knob 90 degrees to wind up the spring? Or are you building an ocean-going vessel, and due to the orientation of the engine and propeller, you need to transmit 100,000 horsepower at 90 degrees to turn the propeller? Or somewhere in between. Explain yourself.
And there are always manufacturer's catalogs. www.sew-eurodrive.com

How much power are you hoping to generate? If you're only after a few watts, you can already (for the last 70+ years) get hub-mounted alternators that might allow you to dispense with gears, worms and shafts altogether.

Despite tens of thousands of efforts and re-designs lasting years and years, there is only a few times that has worked in real life. Call Tupelov. 8<)
RE: Gears
When you were talking about wanting to extract power from both wheels, I thought you must be talking about the second of these things, but once you start invoking multiple riders, I begin to wonder.
You probably don't need to worry too much about the "pedalling at different speeds" problem - that's one of the many things that's been done 'manywheres' and at many times.

RE: Gears
What is the harvested power going to be used for?
12 watts, 12 volts, both wheels ?

RE: Gears
Worm gears are not very efficient. If you use the gear to rotate the worm, you are making a speed increaser. Is that the plan?

Mechanical combination to feed a larger alternator/generator does not have these plusses, and adds the concerns related to exposed shafting, power combination and other stuff.
