Chain normally (in my experience) is a flipping nightmare, chains stretch, masterlinks brake, sprockets strip, etc,etc.
Here is a document found on vex's website "Belt vs. Chain Drive Evaluation" by FIRST Robotics Competition Team 234(credits to 234!)
Hope this has help in some way  |
I really don't understand why so many people are chiming in about chain being such a problem. Chain is a very, very powerful tool if used correctly. It is even more powerful if you DO NOT use master links. After becoming familiar with the dark soul chain tool, I have to say, it is the best thing ever made for chain. 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.
