Awesome - i knew we had some 3d modeing experts here. So what else is needed to turn this into a functional gearbox? 2 gearmotors, 2 shafts, some screws, and (4?) bearings?
Can shafts be lifted from 3:1 gearboxes? Where to get gearboxes? Possibility for some kind of worm drive instead of planetary gearmotors?
Unfortunately, I don't know anything about motors, gearboxes, gear ratios, shafts, shaft couplings - nada. Which is part of what you are paying for when you buy someone's gearbox - the engineering knowledge that went into making it.
Does anyone know a source for electric motors and gearboxes and such, preferably with dimensions?
I wonder if the aluminum components can be replaced with bent sheet metal (if its good enough for an AK47 receiver...). But I assume the motor gearboxes are the expensive part.
The first time I looked at the ETO box I figured sheet metal would be cheaper than the machined billet frame he's got now.
