two cylinders in contact

Hi, dear community,

hope I don't annoy you with my novice's questions but how can you bring two sylinders with parallel axes in contact and the revolution of one causes the revolution of the other in fusion 360?

Thank you for your attention.

You need to create at least 3 components: two axes, first cylinder and second cylinder. Then apply rotation joints to cylinders and their axes. An then use "Motion link" from assemble menu to link that two rotation joints together.

Thank you for your reply. I understand you placed the two axes in a distance R1 + R2 so that the perimeters touch. Is there a simple way to place the big cylinder so that it lies on the two that are already posissioned? I send screen shot.

Is the big cylinder intended to be mounted somehow? Why do not draw this mount first?

The big cylinder would be a carpet roll placed on the other two that will roll it and a cutting disk will cut it. So you think I have to redesign the three cylinders starting from a new sketch with a isosceles triangle? The "move" command has an option "point to point", I wonder if there is something like "surface to surface" or "point to surface". If not, I wonder if that would be a very usefull feature to add. (or am I saying something foolish in my ignorance). Any way, thank you very much for your kindness. Sorry for the delay of my reply but I was away for a couple of days. What are the kudos?

Create mount frame with a slot for top cylinder. Then use joint with "pin-slot" type. Limit this joint to the size of slot. Then create "contact set" between all cylinders, so they will not intersect.

I'm curious, how did you create that roll of carpet? That's pretty neat!

@zaaephod

It's just a square coil in spiral mode. And then "Press Pull"ed to make it prolonged.
