I should have mentioned that I won't be using those narrow wheels from the kit too.  I'm going to be using something closer to 8" diameter, 2" wide pneumatic wheels. That is why I was having a rough time working with the two 21 tooth sprockets on the output shaft of the kit tranny. Their spacing doesn't quite allow for such a simple solution.
I suppose that the best way to solve this problem may be a simple use of spacing on the wheel shafts, leaving the sprockets at different positions on the shafts, but the wheels inline. I'll probably use keyed wheel shafts to make things a little easier. |
You could always just use one sprocket on the output shaft of the transmission and then send that directly to one of your wheels. On this wheel you would place another sprocket on the opposite side of the wheel from the chain coming from the tranny. If you ran a chain between the two wheels like that they would end up being inline. The only bad thing is you use more chain this way.
Now if your comfortable with using smaller chain, which I know some people would yell at you never to use smaller chain in the drivetrain, but we succesfully use the set up I just described on our robot this year without a single problem.
