simulation of bevel gears using contact rather than transitional constraints

Sorry if this is a very basic question but have been stuck on this for a few days now:  I'm trying to run a simulation of 2 bevel gears without using the transitional/rotation constraint, but using the contact between the surfaces to simulate the rotation of the gears - basically I have an L-shaped shaft running through both centers and want to have the upper gear grounded, make the lateral gear rotate around its own axis - the goal is simply to see the contact between the gears make the side gear rotate around the  vertical part of the l-shaped shaft, due to the contact forces.  I think I may need to review the definition of contact types, but not really sure what to do.  Any help is greatly appreciated.

Why not use the Rotational/Translation constraint?

Did you model the gears or are they Design Accelerator created?

The DA gears are approximations and probably won't work well with Contact Sets as they already interfer.

Hi JD,

 

thanks for the reply - that makes sense, there's just too much interference, I'll see if I can't get the same result using the constraints.
