RFI Belt feature on eccentric pulleys

[Rudnie]

Hi Guys

I'm designing a pulley mechanism to change the speed of an oscillating piston. i.e. moving one way faster than the other. I have run into some issues in solidworks as it does not allow the use of the belt feature on such an eccentric pulley. Does anyone know of a separate belt solution or workaround for such a design? Any help will be greatly appreciated.

Kind regards

Rudi

Depending on what you are wanting out of it, could you not draw it manually? If I am remembering correctly the belt feature just gives you a sketch that you can just sweep/extrude or whatever. I know it does some nice things like moving components after you set the belt length and maybe I am oversimplifying it, but I don't think it's anything you couldn't do yourself?

Thanks for the response.
I have drawn the belt path manually however as soon as you rotate some of the components the sketch relations go all over the show.
I am working with offset shafts on round pulleys and that seems to have done the trick.
Will set some goals to see if I achieve the speed reduction I am after.
Thanks
