As I'm sure some of you guys are I have been having some fun lately going through CAD'ing different possible drive train designs. I have a few concerns though.
Three questions:
1) What is a good goal for total weight of the drive train? This would include all frame, wheel, axle, gearing, and motors.
2) I've seen lots of discussion on the smallest you should make your pulleys on a belt driven drive train. Would I be safe to use 18T Pulleys on an exact c-c distance setup with 15mm belts? I know you definitely shouldn't go that small with 9mm.
3) Should I be using the
WCP Belt Calc to get me exact c-c distance or do I need to do some more calculations?
Hopefully you drive train guys out there can give me a hand. Thanks!
Seriously, I figured we had until january before we started lawyering things again. - JamesBrown [more]
