How do I lock 2 gears in a gear mate

douglas_kimber

I have 2 identical gears mounted to a plate. Each gear has a pin that protrudes from the face. The gears are mated to the plate with revolute mates, and to each other with a gear mate. I need the pins to both be at the top together as the gears rotate. This means they will also be at the bottom together, towards the middle together, etc. I can suppress the gear mate and rotate them each to the top, but when I un-suppress the gear mate one of them jumps to a different rotation.

How do I lock them to each other once I have set their relative position correctly, without having them change position?

Here's a demo of the problem I'm trying to solve: https://cad.onshape.com/documents/77f731975463821636bbfea8/w/d522a6e3f970e234226c374f/e/02c3a0353f13160421de2779

Even though the revolute mate allows the gear to freely spin, you need to adjust how it's clocked. You can do this with 90 degree increments using the "Reorient secondary axis" button:

You can further dial in the clocking to whatever amount you need by editing the mate connectors:

However, with your gears designed as is, the teeth don't mesh with both pins at TDC. You'll need to adjust something.

Thanks! I hadn't realized you could adjust the revolute mates by expanding them in the tree. It looks like I will need 2 different gears to get the teeth to mesh and also have the pins where I want them.
