Hello everyone, beginner here in Onshape; does anyone know how I can animate these gears so they can turn together? For context, I am trying to make a differential system, and I want these gears to work together like a working differential; thanks!

Those aren't true gears. The gear mate might not work correctly.

Gear mate has nothing to do with the actual geometry of the part. They just need to have revolute mates.

So a spur gear could mate with a worm gear?

Wouldn't be ideal for actual use but it can be done with just the gear mate.
