Sheet Metal vs Tube Drivetrain

Pushing the pins back in, and using the correct number of links using a chain center to center calculator is about the best thing you can use when designing mechanisms/drivetrains with chain. If you use those two things alone correctly you will never have to worry about tensioning/stretching so long as you use large tooth count sprockets and the right chain pitch for the job. My team used #35 chain for our final reduction coming off our Drivetrain gearbox with fixed direct C-C and #25 chain going from wheel to wheel direct C-C with no tensioners on either and had ZERO issues. We love chain and will continue to use it because it is easier and does not require custom belt lengths for each year or each robot.

While i can not attest to reconnecting chain, I can say with utmost confidence. that belt is by far the easier of the two. Chain stretches making it inconsistent in slop. Belt does not stretch and is more accurate, lighter, cheaper, stronger(depends what kind you get), cleaner , etc. that's one of the reasons it's used in engines (and the fact that it can run at much higher speed without oil) Don't get me wrong. chain does have it's purposes, but drive wheels without any shielding to the chain is not one. (IMO) It's wonderful when making a forklift!
