I am trying to produce, what I thought would be a simple animation. I am either missing the blindingly obvious or the problem is more complex than I thought.
The attached image will help with the description below.
If the big blue wheel moves say 45 degrees in the direction of the arrow, it will drive the chain / belt which is attached to the fixed support at either end,, this will cause the sub assembly containing 2 small rollers and a carrier to move in the same direction as the large wheel, BUT the carrier will not move as far (it should be somwhere around half)
Ideally the animation will oscilate ±45°... but I would like to understand one part of the process at a time....
Thanks in advance
