Re: Gearbox Design for an FTC Robot
Quote:
NeverRest 20/40/60 (all the same motor with a different gearbox attached) Tetrix 12v (almost complete garbage) Matrix (also pretty bad, but I don't have a ton of experience with them) VEX 393 (completely underpowered here) A variety of servos (not what we're looking for) If they're 40s in there, they might be able to lift with 1 or 2 60s depending on their robot's weight, but that also might be slower than they want. It's a pretty limited motor pool for FTC, especially compared to FRC. I don't doubt they might be able to crunch some numbers and come up with a "better" solution, but we don't know what numbers they've already run and exactly how fast they need to pull up how much weight. As for improving it: While this might be fine, generally I prefer to place the motors as few stages away from the shaft they're driving as possible. If you can, I'd second the motion to drive the winch gear with each of the motors directly next to it instead of driving them through each other. This is generally good practice for gearbox design. It looks like you might have small bearings in the gearbox plate-- this is good, keep it up. For something that gets a lot of stress, you want to avoid cantilevered shafts, so supporting both sides is good. Last edited by cadandcookies : 02-03-2016 at 13:46. |
