I was trying to make a planetary gear set without a chain but what ended up happening was that the motor that spins the carrier didn’t change the speed and also didn’t contribute any speed to the final outcome. But might contribute torque but I don’t know how to test this.
I’ve already built a working version with the chain and the only thing I did was move the ring gear onto the inside. The only thing that’s connected to the main axle is the 36 tooth normal gear that furthest from the motors. My code basically says to spin the inner ring gear and the carrier gear at the same speed both times except it reverses the carrier gear speed. Which should change the speed of the output. It would be great to know what I’m doing wrong or if having the ring gear on the inside doesn’t work. Also if I forgot to say something then tell me what I forgot.
This is not how it supposed to work. The direction of rotation for the 36t gears needs to be opposite, and you have them rotating in the same direction.
You will need an even number of 12t gears between 36ts, like this:
They’re super useful, and VEX employees if you’re watching, we would appreciate it if they were sold separately.
Now that we’re on the subject of metal gears, metal versions of the rest of the low strength gears would be amazing. My main issue with the VEX gears is that that bend and the teeth slip, but that wouldn’t be an issue with metal gears.
The OP picture has them using the 12 tooth plastic to drive the high strength, this gear would be their best choice. Put an insert into it if you don’t want the larger shaft.
Hard to say why they havent. I think a lot of people would prefer them over the thicker ones. Good news is it’s easy to cut a 12t metal gear to make one yourself if you need to
