I'm still working on fixing the animations. Did trouble shooting all day, still having issues. IDK if its the curve I am using, or SolidWorks itself - more CAD testing needs to be completed. Fine Tuning Motion Analysis
Motion analysis is used to test/animate the motion of assemblies in SolidWorks. Right now, I figure that if I can't get the cycloidal gear to work as intended in SolidWorks Motion study, theres a good chance that it won't work IRL. I've been having a lot of trouble getting the current rev1 design to animate properly. So, I decided to design a super basic new version of the cycloidal drive to try and figure out where I messed up.
For this isolated test, I increased the 3D contact resolution from the basic version, and decreased the accuracy to these settings: I also changed the frames to 15 fps so stuff would render faster.
To set up the motion study, you need to make sure SolidWorks motion add in is enabled, go to "motion study" and select "Motion Analysis".
I applied a 40 RPM rotation on the motor shaft, and defined contact between the cycloidal disc and ring housing. I also defined a contact group between all of the outer shaft ring pins and cycloidal disc 1 to start. I turned off material and friction when defining contact points, as I'm too unfamiliar with motion studies to figure out how much of an affect they have on your results. I left the elastic properties on the current default settings.
This yielded some good results, as you can see below:

I had some trouble initially setting up the motion study for the double disc operation, as you can see below there is interference meshing between the outer disc and walls.

However, I realized this was my bad: you need to make sure that you PROPERLY line up the output and input pins at the start of the study to get things to move correctly, as the discs are asymmetrical. After making some fixes, I got it to work.

I know solidworks is fine, so now I need to figure out wtf is going on with rev1...
Next Steps
Obvious next steps are testing and refining. Here are the things in particular I want to do
