Re: Prototype transmission for potential use this year

If you put some wide-grippy traction wheels on this you'd be destroying your worm gears left and right. The only reason I haven't pointed this out is because the limited traction of the omni wheels will impart very little force back into the gears in the case of an immediate stop or getting pushed. I'm pretty sure this transmission would not last you more than one competition on anything other than omni wheels. The other issue with this is that the gears will lock up much easier with slight damage and wear than a normal transmission would. Slight bends in the teeth are much more prone to locking up worm gears than normal gears.

Here's a quote from cory (who knows more about this stuff than 99% of this forum) mentioning the dangers of using worm gears and relatively soft metals for drivetrains. This comment was from the first picture that softwarebug2.0 posted.
