Hopefully you drive train guys out there can give me a hand. Thanks! |
That URL will work to give you a good center-center distance. That said, if I were you I would also implement some sort of tensioner in my drive to keep my belts from slipping.
Personally, I love #35 chain over belts because chain does not have to be as precisely tensioned and most powerful (4 or 6 CIM) FRC drive applications are actually a little out of spec for either HTD 5mm belts or #25 Chain.
I look for robustness first in a drive, and for that reason chain (with a pair of direct driven wheels) is my favorite torque transmission solution.
A good drive weight depends on the type of drive. For the 6-cim monstrosity that 3061 ran last year, 35 lbs was the target weight not including control electronics.
