The design of this gearbox was heavily
inspired by other FRC teams who posted pictures or full 3D models of their designs. Admittedly, I am not the most creative designer (steal from the best, invent the rest, right?), so the inspiration is fairly obvious. In particular, the design was inspired by Team 254 and Team 973, who have been gracious enough to share their designs.
I designed my gearbox entirely in Autodesk Inventor before purchasing a single part. I started by choosing a gear ratio (which you can learn more about here
), and then ensured that there would be no clearance issues between the rotating parts using the sketch shown in the second picture. This sketch also helped me define the exact shape of the gearbox plates. From there, I designed the rest of the gearbox, part by part. Throughout the design process, I had to ensure that I could make each part that I designed on the tools available to me.
