Planetary Gears Motion
See attached file. I added one more joint then 4 motion links. If you enable component drag you'll be able to drag the gears around.

Don't know if you're going to try and make this but you have a problem with the outer gear. Actually thinking about it a bit more the problem is the small gear, gears with less than about 20 teeth need undercuts to get around the problem below. There's some info here if you're interested.

What do you want help with, the joint setup or the gear under cuts?

@zenkustumz First off you've made quite a mess moving bodies around instead of components, it took quite a while to fix. You should have just used Joints not the Move command for this.
Here you can see your origins are all over the place and at odd angles.
The first thing I did was move all the bodies back to their origins and reset their rotations. Then I made this screencast to show a workaround for the undercut, it's not perfect but it's works with a rack, you'll see at the end it doesn't quite work with your ring gear. In the attached file I've cut the centre of the ring gear a bit bigger so I could add fillets as @TheCADWhisperer suggested. I also added 2 more fillets to the small gear.

Here's another screencast that shows how to make copies of the small gear and finish setting up the motion links.

Attached are Module 2 gears created in Gearotic, so the tooth form should have the correct form. They are in stl form, so you can use the mesh tools to create a regular 3d model.
