Roller Following A Tube

[ScottJohnson]

I have a set of rollers that when I drag the assembly need to adjust the angle of the rollers. I can do it in one section of the tube, but not the whole length. How do I identify the mechanisms? I did best with a 3D contact. The parts are highlighted. Move the orange assembly, the magenta rollers adjust around the cyan tube and rollers stay on each side.  This post was an admin edit and originally posted on August 11th 2023 8:27 AM

I'd say what you need is a Slot constraint. Put a point in between the rollers and have a curve that follows the center of the tube. Slot will let the point follow the curve. Then you need a second constraint, such as a Planar, to keep it from rotating.  This was an admin edit originally posted on August 23, 2023 7:55 AM
