Doug,

Thanks for the interest. Bill has it right, but I will be more specific.

This design idea came from Steve Butler, an engineer on our team who was into racing. I made the detailed design, using his idea, and put it on our 2002 robot. This is a more refined version, put on our 2003 robot. Clark and Kyle Gilbert made this model in Inventor and created this nice "cut away" view.

The aqua colored parts that fit inside the gears (green and blue gears) are 3/8" id flange bearings. The gears freely spin on the red shaft and transfer the torque to the red shaft via the orange "dog" gear.

The purple and white bearings are the same as the aqua bearings (3/8" id flange ball bearings). They were just shown in different colors for clarity purposes, I believe (the Gilberts' idea).

I must say that these gearboxes really performed well for us this year. We had some drivetrain problems, but none were due to this gearbox (other gears and belts outside of this gearbox were more problematic).

My plan is to do an extensive white paper on this improved design and release it by mid-June. Next year, we'll probably use this design again, with more improvements.
