COTS & Custom Worm Gearboxes

[Rauhul Varma]

Can anybody with a RawBox comment on it's backdriveability?

While I do not have very much experience with the AndyMark RAW Box, I did play with it at champs and it is based on our 2012 gearbox. Our gearbox was designed to be very high efficiency (for a worm) and be backdrivable so we used a 4 start worm which (IIRC) AndyMark used in their version. The RAW box is therefore most probably backdrivable.

Worm drives are backdrivable, but it takes some torque. The four/two start worms will backdrive pretty quickly after being worn in, and if you load a 1 start worm enough, it'll back drive. I'd be willing to guess that this is for some surgical tubing launcher thing, and my suggestion is to use a transmission from a dewalt drill (remember those?). They don't backdrive.
