Mating two threads

Hi,

anyone have an idea who to mate two threads together.

Take for example a vise with one moveable jaw and one fixed jaw. Is it
possible to mate moveable jaw and leading screw so that when you
"turn" the handle moveable jaw moves? I am especilally interested
mating the threads in those parts..

Thanks!

If you don't really need the rotate/screw action, you can just slide the
leadscrew in and out and the movable jaw would go with it. If you are
really good, you could rotate and slide at the proper ratio and make it
appear to thread itself through.

Thanks to all of you!

It wasn't so hard after all.

Contructing true threads may be a nightmare for performance. You could
mate a point on a jaw with an helix curve on the vise. But I found a
better solution for SW2004. First create a dummie part made only by a
sketch with a circle and a point on its circumference. Bigger the
circle diameter, better the simulation. Put your dummie part in your
assembly and mate coincident the point on the circle with a face of
the jaw. Add a gear mate between the leading screw and the dummie
part. The gear ratio controls the speed of the jaw. Hide the dummie
part. For better simulation add a tangent mate between the circle on
the dummie part and the cilindrical surface of the screw. Rotating the
screw causes the jaw to move along the screw axis.
