Re: Worm Gear Gearbox

I will vouch for the workability of the worm gear gearbox in a drivetrain. In 02 my high school team tested it. Just make sure that you pay attention to the forces that your gearbox will be subject to, and lube like a madman. The forces don't work out the same as with spur gears as there is more axial force on the worm gear and worm, so putting a large amount of force through a worm gear gearbox can cause an improperly considered structure to flex and bind even if you were precise in your machining. (it can still work just design the box structure and shafts to take the forces)

Also make sure that you check the torque ratings on your gears. The fact that they don't backdrive also means that much of the shock of hits goes soley to the teeth of the worm gear.

We also got our gears from boston gear.
