Worm System

13 October 2010, 22:12, by Imagineer2017

I recently built a Unimog (my own design, though I do love this one), and used a worm gear. Although slow, it worked well.
I wanted some more speed, so I used gears and removed the worm, resulting in a 1:1.429 gear ratio. Problem is, it would move about an inch, then the gears would slip.
I checked the transmission, and all the gears were still in place, the structure hadn’t failed. Also, it is not 4WD, so could this have been one of the factors causing it to slip?
Any suggestions?

Many thanks!
