I have been working on a robot for the Science Olympiad Robot Ramble event. I’m using chains for some parts of the lift arm and a door on a box, but I keep breaking the chains. Due to size limits of the event, I do not have room to make a more efficient, complex chain system. I have decided to order metal roller chain from an industrial supply company, and would like to know the pitch (in inches) of the chain so I can still use the Vex sprockets with it, as the other company’s sprockets sell for $10 each.
I haven’t read the definition of “Chain pitch” recently; but I’ll bet that it is the same as the pitch of the sprockets and that by counting the teeth on a sprocket or two; and by knowing the diameter of those sprockets, you can compute the pitch value you need.
