Hey guys. I'm doing a project on designing epicyclic gearbox. You are meant to be able to change the ratio and the diameter of the sun gear. The problem is that I can't think of a way to make them always mesh. So any ideas??

You will need to carefully check your radii, gear ratios, initial angles, and number of planets. This can all be related algebraically, and some of these items will constrain the others.
