Spinning a Lego wheel FAST!

I’ve modified the Saw whilst I wait for the metal blade to come! Lets see just how fast you can spin a Lego Technic wheel! 50,000 RPM?
I’ve used 14 L motors and 6 powered up hubs with 7.2v rechargeable batteries!
I lubricated the axles with olive oil to prevent damage!
I had fun doing this one :)
Welcome to all the new subs! It’s greatly appreciated 😀

That crazy fast and you should make a mechanism where it releases wheels at full speed!

[@GazRsExtremeBrickMachines]

Chris that’s a really crazy but good idea! Any ideas how you do it with two axles like here lol. I will be trying with half of the machine tomorrow! 😀

[@chrissbrick4989]

@@GazRsExtremeBrickMachines maybe you could use gears that don’t have friction on the inside and have a motor pull the axle out

[@GazRsExtremeBrickMachines]

I’ll experiment later! I’m wondering if it works will the tyre just sit there spinning on the spot until it realises it should be going forward… I can see quite delay until it gains traction!

[@chrissbrick4989]

@@torbendk2777 yeah

[@Mr.Pidgeon]

The reason that the higher ratios don't make that much difference is that it takes an amount of energy to spin it at that speed, changing the ratio is like the length of a lever, yes theoretically youd achieve more speed, but you'd need more power to do it

[@GazRsExtremeBrickMachines]

Yes agree it didn’t have the torque with the big wheel! I’m using 22 motors next time so will see the difference! Thanks for the comment 😀

[@VINCE-pp3es]

@@GazRsExtremeBrickMachines and use some wd40 if i remember what this vid showed kzbin.info/www/bejne/qWSlpHd8a7qdebM

[@carlsberg1668]

I get what you are saying but usually a longer lever helps reduce effort/power needed to move a load. Having said that, if you increase the length of the lever from the fulcrum without increasing the thickness/strength of the lever you will run into problems. Or am i missing something?

[@GazRsExtremeBrickMachines]

Cheers Vince

[@Mr.Pidgeon]

@@carlsberg1668 that's more or less correct, it takes x power to move something, in this case spinning, so changing how the power gets there doesn't make a difference

[@quinnobi42]

I think that you could increase the maximum RPM by a good bit by swapping all of the bevel-type gears to the standard spur gears, which have less transmission losses due to the smaller teeth that mesh better.

[@GazRsExtremeBrickMachines]

The bevels did surprise me as I thought they had more friction! You’re definitely right though! Improved version in a week 😀

[@dlux6700]

@@GazRsExtremeBrickMachines Can't wait for that!

[@dallagen3423]

@@GazRsExtremeBrickMachines I would also recommend using a better lubricant than olive oil for the gears and axels, a teflon suspended pfpe grease would probably work phenomenally and minimize losses

[@BeastOfSoda]

Yup. I'd say something like boron nitride, which is the stuff used to lube moving parts in RC cars (one such compound is Tamiya Cera Grease); another good option would be PTFE, WD40 comes in one such formula.

[@K-Effect]

I would be so afraid of something shattering and the pieces flying into my eyeballs. But besides that very cool

[@GazRsExtremeBrickMachines]

Lol Kevin i did get nervous here when the tyres were on! Also you can see me with the saw at the end I’m clearly afraid and it’s only plastic!! And thank you very much 😀

[@DagoDuck]

‘Only plastic‘ That could be the worst last words someone would have ever said. If spinning fast enough, it‘s even possible to cut through hard plastic with paper. (There is a video in which someone cuts some scissors with a spinning piece of paper)

[@GazRsExtremeBrickMachines]

I’ll take a look at that thanks! 😀 I was aware though it was quite dangerous, just the noise it made was quite daunting.

[@djsomeguy]

@@GazRsExtremeBrickMachines you definitely should be wearing a full face shield at minimum...but I'd really prefer a solid piece of plexi or something between me and something spinning at that rate. A small 4cm wheel spinning at 50,000rpm experiences something like 1100+ g's and has a surface speed of somewhere around 40km/h. Looking at a lego wheel chart, at 4cm they're about 15g...which works out to a apparent weight (based on the g force) of around 16 kilograms. So to put it in perspective, imagine getting hit with a 16kg weight traveling 40km/h and that's roughly the amount of energy contained in that wheel. That's only accounting for the weight and rotational energy of the wheel and not the rest of the gear train either. (Very rough math, probably a bit off given I'm assuming all the rotational energy is translated into linear energy but it's in the ballpark and makes a point)

[@GazRsExtremeBrickMachines]

Hey there thank you for that and I will do! Fascinating read it’s much appreciated and put s things into context 😀

[@Logarithm906]

lego pulley wheel with a 24mm rim spinning at 731.8 times a second works out to be 0.024*pi*731.8= 55.18m/s at the rim. Which is 198.6 km/h or 123.4 mph

[@GazRsExtremeBrickMachines]

Hey great thank you! At a rough guess then the larger wheel was covering more ground?

[@GazRsExtremeBrickMachines]

Indeed!

[@paulsmyers203]

You mention oiling the axles, but what about the gear teeth? One drop on each gear pair might net you a few more percentage in final output rotation speed. Obviously add the oil when it's at low RPM or it'll just get splattered everywhere ;)

[@GazRsExtremeBrickMachines]

Hey nice suggestion! I did do it btw you might be able to just see them shine, maybe. This difference was very noticeable aswell! I’m making a new rig now with 22 motors to see if it can pull the 1:375 ratio😀

[@girishbh7816]

small wheel: instantly decelerates Tire of small wheel: spinny spinny boi

[@GazRsExtremeBrickMachines]

I was really confused at first at what the noise was until I saw the tyre was spinning so fast still lol

[@fluz1006]

I see the wheels can’t reach theoretical top speed, since the friction is overcoming the torque power of the engines, i recommend lowering the gear ratios to get more torque, since you don’t need those insane ratios with your current power Also, try to use bigger/smaller gears for the ratios, since those will be lead to less friction in numbers

[@GazRsExtremeBrickMachines]

Hi there nice comment! I was struggling for the bigger gears so I may need to change the setup and you’re right there’s less friction with them. I thought the second to last ratio was the optimum though with this power despite losing x % Any lower and it lost speed like the one before! I’m using more motors next time(22) so I reckon the second to last ratio will get nearer to its potential! The last ratio was very hard to turn😀

[@microwave3497]

I love how it starts to sound like an air raid siren.

[@okboing]

One thing that's hard to notice unless you hand crank the wheel is how it can go from really resistive to smooth like butter as soon as the wheel goes from wobbling to loosely holding on

[@aadityajain5286]

With the tire is a prime example of why we construct car tires with metal fibers in a special pattern.

[@leftaroundabout]

The metal fibres are mainly needed so the tyre can contain the air pressure without ballooning up to a round shape that wouldn't have good ground contact. Against _unseating by centrifugal_ forces, the tyre bead would be enough.

[@zackschwenzer4892]

I'm no Lego expert but I'm still surprised the plastic wasnt trying to melt at those speeds. I'm sure friction still exists here.
