Re: COTS Worm Gearbox

The raw box is pretty hard to back drive if you set it up right. We consistently put 30-50 foot-pounds of torque on it each time we lifted 4 totes last year without backdriving.

We input 2 CIM motors into 10:1 VP's with CIM output shafts, then ran those into the RAW box.

If you keep the lever arm short enough, the raw box is going to have a lot less torque on it than that.
