Rope and pulley modeling

Out of category

Hello

I would like to model a system of 3 pulleys including a pulley serving as a tensioner (one on the left, one on the right and between the two the tensioning pulley), with a Ø25mm rope.
The rope would make one full turn on the left wheel, two full turns on the right wheel and would be tangent to the upper part of the tension wheel.

I found this tutorial: https://openclassrooms.com/fr/courses/1553986-apprenez-a-utiliser-solidworks/1556643-exercice-une-courroie but this example doesn't take into account loops and therefore doesn't allow you to work on staggered shots. By following this tutorial, I find myself with an error message telling me that the sketches intersect (which is normal if you work on a single plane).

Is there a solution to represent this rope with the different turns on each pulley? I'd also like to create an animation to show the tension of the rope when the tensioner pulley is moved, and the rotation of the pulleys when one is moved...

Thank you!

Hello look here

or look there

it must correspond to your request if I understood  correctly ;-)

On the other hand, if I read correctly to do several turns, it is called a drum and no longer a pulley. It must be possible but I have never tried.

EDIT
in fact it exists look at the instructions here   ;-)

Hello

Thank you for your answers, I used a mix of the two to create my rope.

This one is not animated, but the dimension is realistic.
