You need a flywheel on the highest Gear so it stops constantly losing momentum every time you stop cranking
@1992jamo 2 роки тому
Which would make it incredibly hard to move the crank at all. There is 512+ (include friction) times more torque to spin the crank. There is a reason he made the gears lighter towards the output.
@ZeldaIsMyLove 2 роки тому
@@1992jamo I'm curious how that would balance. A decently weighed flywheel would take more force to move, but would lose less to fiction. Since acceleration isn't important, it could theoretically go faster. Especially if he started at the flywheel.
@1992jamo 2 роки тому
@@ZeldaIsMyLove If the flywheel takes 0.5Nm to move, it would take 256Nm on the input shaft to move it. If the crank is 7cm, that's 3657N of force required at the end. That's 373KG of force on that 7cm crank, to get just 0.5Nm on the output shaft. Moving the flywheel first would work, but if it slows down even a little, it would be extremely hard to add energy back into the flywheel.

@TheRealLoganYT Kind of like how older axes are done so the handle can hold the axe head without worrying about the axe head flying off. If you look up videos of people making their own axe handles you'll probably see an example. Lots of machinery use keys in places where they have rods/axles as well (though positioned differently) because the key becomes the shear bolt so if anything is going to break, it's going to be the key instead of all the expensive stuff. The kind of things engineers have come up is pretty darn neat, god bless 'em

@Whyyyyyy 2 роки тому
Some ideas from an engineering dropout, rather than substantially thinner gears on the faster end, decrease the infill on the print, you're losing efficiency from the thin plastic flexing as it spins fast. Some combination via trial and error may be needed. You're never going to get adhesive bond to an axle to hold the kind of mechanical advantage you're working with on the handle, it's surprisingly easy to key a shaft with a dremel and then use a dab of jb weld to secure the key. Lastly, bearings might seem like cheating but you should definitely have something there. Might I suggest brass bushings and a bit of lubrication? They can work a dream and aren't too difficult to make.

Ceramic ball barings on the shafts, Taller mount so you can move it if needed. A keyway on the handle and shaft connection with a metal washer cover for the rear part up against the mount. A solid handle with a handle that rotates with the gears. Gear (the first gear) that can be locked down onto the drive shift with a keyway or flat ends of grommet screws onto the drive shaft. Maybe a clear cover so you can put a light amount of lube on the gears. Separate the gears on different shafts to make it easier to turn instead of just two shafts. Or put the gears after the first gear on barings.

Obviously bearings and lubricant would help, I also had the idea to go up by each gear but you covered that here. I think each gear should be solid on the outside like youve done previously. My only other fun idea would be put golf ball pips on the sides of the gears
@rajinkajin7293 2 роки тому
Golf ball pips would probably not help in this application. Hear me out. Golf ball pips do increase the range of golf balls by decreasing NET drag, but there are two different sources of drag at play. First, we have "frictional" drag, where the air that is stopped rubs against the air that is stuck to the surface of the object. Second, we have pressure drag. I'm terrible at explanation, but imagine a bullet traveling through water. If the bullet was traveling fast enough, as water has momentum, it would "jump" off the nose, and then come crashing back down together. The void that is created is very low pressure, and literally sucks on the bullet, slowing it down. Golf ball pips INCREASE frictional drag, but this energy goes into creating turbulence that extends the boundary layer, or the area around the ball where relative air velocity transitions from matching the ball to stationary. This causes a lower tendency to suffer from flow separation, and thus decreases parasitic drag. The same effect could be achieved by having a teardrop shape, like hypermile cars, but balls must remain rotationally symmetric. A gear has a constant cross section when rotating, save for the teeth, so I believe pips would only increase drag.

The spokes in those last gears might make them lighter, but it's also going to add drag. A solid gear with less infill will the job done better.. It'll probably help keep the fastest gears better in-circle as well. The last several gears would benefit in being balanced. The vibration and wobbling adds a ton of drag and is causing most of the plateau you are hitting. Reducing tolerances between the gears and shaft would help with that as well (+1 on the idea for quality ceramic ball bearings). With those tiny changes, I bet you could go a lot faster, and probably with much less force.

reduce vibration by improving light gears quality ( check equilibrium ), maybe add metal tube between gears and axes to reduce clearance, or use bearings on fastest gears And remove gear teeth on last spinnner to reduce air resistance Other idea: add a carter around and between gears to reduce air fluctuations

I mean, if you had durable enough materials, and a strong enough cranking mechanism, and enough gears... You could reach the speed of light. Odds are though it would require more force to turn than is possible to generate. X.x

@chrisseddon5823 2 роки тому
The final gear's perimeter is hitting less than 300km/h. It would take a force 3 million times stronger, with almost infinitely more durable materials to achieve this with the current conditions. Create a zero friction and resistance condition and it would still take a force way beyond our capabilities. And it would still break.

I love when companies say "stronger than steel" for processes and force that don't really apply to the strength of Steel. It is strong? most likely, but it is such a marketing term I can't take it seriously anymore on like... the tensile strength of balloons or trampolines.

You should use lubrication Mostly to reduce generated heat. Also scale down the last gear a lot so you have even less spinning mass. On top, maybe try belted gearing. It's more efficient! And use bearings for the gears

I am sure the suggestion is here, but I would flatten the sides of the main shaft where the handle connects so you can get so more torque. Second you can get a laser tachometer for under $30 to give you a pretty accurate read.

Definitely faster than most cars. I've been driviing karts a lot though and they still come out ahead. The largest RPM I've seen there was 17k RPM, my own motor got up to a max of 15.5k RPM. Gotta stress how not common this is for an engine with gears though. Even racecars tend to keep it below 8000-9000 RPM. NASCAR, F1, Indycar and similar go over.

That's great! I've been investigating how to easiest make a DIY oil filter centrifuge. But as I have zero experience with welding I wondered if it can be done with (tough) plastics. The main trouble is of course to have the spinning cylinder survive safely very high RPMs. 9000 RPMs are more than plenty for my purpose :) But now I also wonder if using J-B Weld with stainless steel parts (that will be spinning at several thousands RPMs) would be good enough.
