If by "gearbox" you mean "Pulley" -- a setup such as this is probably most efficiently done by just putting a big (wide) pulley on the front crankshaft accessory belt and correct diameter pulley on the alternator, to get to whatever the target RPM of the alternator and whatever low RPM works under maximum load for the motor. Put the whole thing on a reinforce pallet and you're done.
This whole setup almost certainly isn't going to be able to supply "north america normal household power demand" volumes of power reliably for months at a time, but almost certainly do whatever a cheapo generator was doing before that cheapo's sketchy 150cc motor crapped out.
- bluGill 3y agoBy gearbox I mean anything to change from one RPM to another. Chains, belts, or gears are the obvious options. They all have pros and cons, but any would work. There are other options as well, but they tend to be a lot less efficient which destroys the whole point.
- lostlogin 3y agoI’m very much not an engineer, but a below and pulley changing the ratio seems the most efficient.
- worik 3y ago> By gearbox I mean anything to change from one RPM to another I thought you meant the car's gearbox
- bluGill 3y agoUntil people replied I hadn't considered that. It would be an option, but I was thinking about a surplus gearbox which you can sometimes pickup with a fixed gear ratio.
