High Torque Gearboxes

[AdamHeard]

If you're talking within the realm of COTS FRC, something has to give here.

With single CIM, the GEM500 from Andymark is reasonable.

If you provide another reduction after it, the plastic 3 stage gearbox from Vex would work too. Even if you paid to get some plates cut to build another stage it wouldn't be very expensive.

COTS gearing from other industries is unlikely to accept dual motor input, so that will rule out a good deal (you'll also find that gearing for pretty much any other industry will be more expensive).

This breaks the versaplanetary.


EDIT: Worth pointing out that 2 CIMs at 70:1 is enough torque under stall to break many things that sometimes are assumed to be bulletproof in FRC. You'll want to verify the material for the output shaft can handle the torque (along with whatever the output gearing is) and/or limit the systems ability to maintain full stull at full voltage.
