@hyperundead Forget physics class. I designed this originally before I was even a teenager. It is much like a transmission. And is works because of my magical powers.
@makmegs 1) I am actually a construction blueprint estimator (I do VERY accurate takeoffs). I have A BS in Electronic Engineering and I have been writing computer software since age 12. Mechanical engineering has been a hobby that ties those two things to the real world. 2) See SergeTTL's comment. This is a proof of concept, an RC motor would make the wheels explode ( = 3) I have dismantled it already, but a clutch would be quite possible and necessary (I think). 4) Thanks! My 1st video.
this is quite clever. I have made a transmission based on the Dixon ZTR cone drive, used two plastic gears instead of cones and two small rubber wheels instead of dishes. here is a photo of the real thing:
@bachaddict I can't seem to bring up the pic (and yes I changed the DOT). I actually made a few dual cone designs with rubber bands prior to this. They worked fairly well, but they were a bit flimsy. I do wish to see your picture when you can find a workable link. Keep tinkering!
@ksp420 sorry about that, don't know what happened. go to their home page, then click on "Dixon ZTR Photo Gallery" then "Dixon ZTR 4421 Project Photos"
that should bring up photos of the inside.
will look at putting photos of LEGO model on flickr or similar
The point is, if you were building some sort of motor driven lego model, you don't have to vary the speed of the motor, you can have a purely mechanical way of changing the speed of the motor. The advantage is, because the input is always the same speed, the torque (or turning power) increases as the output gets slower, whereas with an electric motor it decreases.
I wanted to say thank you to all the great comments. I just wanted to share an old idea with the world. This is a design I came up with when I was 12 years old (~17 years ago). I threw it together in about 30 minutes and put the video up. I never expected 10,000+ hits! If anyone has a video of their designs, post them! Thank you and keep on building! 420!
I think you are correct, sir. But you could daisy chain them, even if scaled down, and create a wider range of ratios. You would lose circumference but gain length. I haven't thought about it in a while. This is a design I came up with when I was 12 years old (17 years ago).
It is a transmission that has an analog amount of output ratios, unlike your car that has four or five gears, this one has "infinite" and it slides up and down smoothly. No jerks for shifting. Imagine getting to 100mph and your engine running at 1000RPM (hypothetically), from stand still to top speed. Just maintaining friction at high temps is a problem in real world applications which speeds and power are great.
Thanks! Now I have to hook up an rc car motor to this. Just to see how fast I can get it before one of the pressure plates explodes. This could be fun.
You've gotta film this if you're really gonna do this! Maybe an additional rubber wheel on the opposite side of the brick wheel will be needed to achieve sufficient pressing and cohesion. BTW you could put some suspended paper around the wheel to watch it being torn into pieces and to better visualize the explosion :D.
Very cool, and I get how it works too, at first I wasn't paying too close attention, but I saw the mechanism in the middle moving. I want to make this now...
this is the way some lawnmower transmissions work. the ones with lots of gears. Just a wheel on a keyed shaft tho which would be hard to make with legos
Has a lego hit you in the face from it spinning to fast?

1. Are you an engineer of some sort(Mechanical, robotics?)
2. Have you connect the rc engine to it yet :P
3. Try building one with a clutch (if thats even possible) :P
4. This is not really a question but really good video dude! Glad you shared it with the rest of us for :D

@ShokaLion That's a much better explanation than mine. Thank you.
ksp420 1 year ago
You need to work on it some more and get the input and output running the same direction but I do like what you have so far.

it is a very very good idea but not very useful due to its large size if scaled down it would reduce the amount of ratios possible am i right?

Great variator! But it looks a little scary, because your output lego wheel can explode while rotating that fast... :D
