Dear all,

I am currently putting in place a linear guide. This assembly is composed of 2 pulleys, a belt (showing in red on the joined photo) and a sliding plate.

Currently I can create the belt/chain system between the 2 pulleys (excluding the sliding plate): this works fine and when I rotate one pulley by hand, I can see the other one rotating accordingly.

Now I am actually expecting the belt to drive the sliding plate. i.e. I am expecting to link the plate to the belt, the belt fitting a groove machined in the plate (showing in yellow on the joined photo). The belt is supposed to be tightened to the plate by a part not shown on the joined photo).

The problem is that the belt/chain feature does not seem to accept flat surfaces as input. I was actually expecting the belt/chain feature to cope with flat surfaces in order to have:

   * the belt deform to account for a misalignement between the belt and the groove,

   * the plate driven by pulley rotation (to transmit power from the belt to the plate).

I thought my design was really common and would be handled by SW out of the box. Did I miss something?

Do you have any idea how to design such a system in SW?

I have joined the assembly and part files of the exemple for a clearer view.

Regards,

Antoine.
