Re: [FTC]: Drive Platform- Design Exercise

Big Wheel Design

We did some design and testing. We modeled the AM-0420 8" Wheel with an automotive "cogged V-belt", model # AX-23. The idea is that the belt will be flipped inside out and snugly fit the wheel OD. We're thinking well cement the 2 rubber surfaces together.

The auto parts store didn't have this small a fan belt, but I got a longer one with the same cog pattern and cross-section. We mocked up the 50 deg angle with a churro at the correct alignment, rigged the belt around an 8" wheel and rolled the wheel per design by hand. It felt like it should work; worked well enough that we ordered 4 wheels and 4 belts.
