So I modeled one of the Wankel Rotary engines from here on Grabcad. Unfortunately, it wasn't complete I'm now finding out as it's missing an essential gear to allow for rotation. In part of me using this as practice, I wanted to animate the engine so it properly rotated.
Here is where I run into the problem of this missing gear, that I have circled in red where it should go. I need to create a gear around the shaft than lines up with the green ring gear to make the animation properly work. Could someone give me a bit of guidance of how I will go about making a gear of smaller size that will fit the teeth of the larger green gear? I can upload any/all of the files if need be. Thanks!
