A spring for a spring?

[Ganser]

Hello everyone:

After reviewing the threads and not find an answer, I pose my dilemma.

I'm trying to simulate the behavior of the spring shown in the illustrations, in which I put the initial and final state, with maximum compression (about twenty degrees).

To achieve this, one of the moving parts (Partes móviles in picture one) will receive the pressure and the other -spiral- must rotate accordingly to this pressure (at least as I understand it). The part marked as fixed (Parte fija, in picture one) is backed against a stop and does not move.

Well, I can not simulate it without "breaking" the piece.

I would appreciate very much any suggestions or recommendations to make it work.

Thanks in advance.

Cordial greetings.
