Drivetrain question (Cheesy Poofs)

Ah okay that is pretty interesting. And it seems that the pillow blocks have a little part for tensioning. Thanks for the help!

Here is an actual picture of the 2 halfs. The left one goes on the inside of the frame and slides into the one on the right which is mounted outboard of the frame.

I noticed that 968 would tighten a bolt in the front of their frame to tighten their chain. How would that bolt interface to the piece pictured above? I don't see a place for the bolt to attach to the machined part.

There is a steel cam that pushes up against one of the edges when it is turned of the inner pillow block which moves the block.

Only on our robot. As can be seen here

968 tensioned their chains differently. Travis can explain how when he sees this.

We had an aluminum clevis that bearing housing screw went through. Tightening the bolt would thread the bolt further into the clevis and would in turn pull the bearing housing assemblyy outward, tensioning the chain. The weight is negligible between the two, we just didn't have the time to make the cams.
