I remember that I was making a sketch of a gearbox 1 or 2 weeks ago, using 17T and 84T for the first stage, and it did work.
After plugging in values into JVN, I'm getting 18.91fps for high gear and 7.88fps for low gear. I think the low gear should be around the 6-range if the robot were to last longer in a pushing match. Also, those gears are coming out to be pretty large (there's a 84T, a 50T, and a 70T). At this point, I would consider keeping the weight at a minimum and look for another solution.
What if there was something like a large idler gear (singular) above the 84T gear, and the CIM gears go to that idler gear, and instead of shoulder bolts, I can have that gear be mounted by a hex shaft secured on both sides with some sort of retaining ring?
