It’s really weird to see how unnecessarily complex this mechanism is when it accomplishes the same goal as the first mechanism you built.

[@simonebraito3059]

Yes but you have a turn point in the midle while everything is blocked and you have 2 diferent point when it turns, so it minds that you can give two separate works. I mean, this type of mechanism you create it when you need it, not you create the mechanism and after you think how to use it

[@sheriffsad835]

The difference is that the secondary wheel rotates around the same axis as the input shaft. It’s Used in watch making since it’s incremental like the first one, but is used when the output needs to be in line with the input.

[@suicidalbanananana]

Im pretty sure it has a smaller footprint though, so that's likely why somebody even came up with this variation.

[@tbuk8350]

It seems like a combination of the mechanism he built that is used in old film stuff (the one that converts rotational movement into increments and the other mechanism that converts rotational movement into linear movement.

[@raphaelc9492]

@@suicidalbanananana these mechanisms often dont need a real purpose else than be buildable and precise cuz it looks for me like a test mechanism for people learning these things to build. so basically you get a building plan 3-4 months before you need to deliver this like a doctor or professor for his title to legitamently have dr. or prof. in germany if you want your master in many industrial jobs you need to do something like that if you are working in the metal industry and often this piece is only the testing for the actual build and its the meaning of them to be complex and precise cuz thats whats the test for to test you and not the mechanism. sry for my bad english im german and dont know all these words in english and google was down^^

[@TheTechAdmin]

It's a basic moving gear to solid dock mechanism. You can use it to do a solid shift of a minute hand, with the center 60 gear being constantly moving. Or a solid day shift hand, with the center 24 gear constantly moving. It's a design that allows the same goal as a Geneva device, but with a more stable transfer for higher ratio changes.

[@fireflightphoenix8710]

Hey Scrapman, at 15:21 you removed a block, that block was next to the purple, and it definitely was why the purple didn't slot in, as that was the only change you made between it not working and it semi-working.

[@techstuff9198]

It's because that point in the circle was rubbing against the stationary frame, among a few others that didn't cause dramatic failures.

[@final_catalyst]

Yeah, it was making just a bit extra friction so it would not go as far

[@aggeloskomiotis5432]

Well that's a 360 degree counter. Every full inner cycle is one "tik" on the outer.

[@DanielMether]

I assume you could add more disks under it with each disk pushing the next every 10 rotations to create an anolog rotation counter then.

[@magentawool2556]

@@DanielMether like a clock

[@myusernameisrighther]

Yeah, this is how an escapement mechanism works. And the yellow part is to stop unwanted rotation and ensure that regardless of other forces outside this mechanism will not adversely affect the movement. This could be used in a clock, but an analog clicker counter seems more likely. I agree that they would likely be stacked with a mechanism that turns the next disk in the series by one tick.

[@fredneckpetersw4100]

[@tuluppampam]

[@Wasbever_14]

Ey Nederland

[@Jamesdavey358]

Hey scrapman, I'm leeching off this comment so you'll see this but the inner wheel shouldn't be attached to the big green wheel. This causes the rotation the speed up / slow down when the big green one rotates

[@jipsvlogandgaming380]

The mechanism seems to do the same work as a Geneva drive so probably in some clocks or something

[@tdoyr]

It’s always the clocks that have the weird ones

[@bluecat2991]

I'm inclined to agree. Especially because a Geneva drive would require another pivot which there might not be space for.

[@thetos]

It also looks like it would have a different acceleration/deceleration than a geneva drive, it seems smoother. Maybe it could be used when the acceleration of a geneva drive is too brutal for its application.

if you build it on a bigger scale you can mitigate a bit of that "not 100% the exact degree due to grid building" due to how much 1 degree differ from 1 meter away vs 10 meters away

[@foxracerdrew]

Beginning to think that adding some of these mechanisms together to make an actual working mechanical clock would be cool.

[@suicidalbanananana]

I think the problem is related to the distance between the center and the pins on the big wheel, because of being limited to the block grid that distance means slight variations in angle, i feel like moving the purple pin inwards by 1 block would've put it more in line with the 36' angle difference of the rest of the pins. That said, it still made for an interesting build, keep these coming! :D

[@dutch_and_dimes]

Glad to Assist you with your Dilemma ScrapMan! This Mechanism is what we call a Rotation-Based Counting System! This Mechanism Measures 5 Full Rotations per Full Revolution (1800/360 Reduction). This Application, if utilized in Mechanical Clocks, would be used to measure One Unit of Time over Five Subunits (1/5 Reduction), which effectively means you're Measuring Seconds-per-Minute (or Minutes-per-Hour) over the Course of Five Rotations, which is Twelve Seconds (or Minutes) per Rotation. (60/5=12). Scientists considered changing the Standard Time Reduction to Fifths instead of Sixths, but later Rejected it because of Potential Inaccuracies that could add up over the course of Years. The more you know!

[@johns1307]

That hug bit put some tears in my eyes...

[@mathisurien4031]

scrapman, i'll try to explain this system as simply as i can. this is a form of intermittent gearing (it serves a similar fuction to a geneva drive in sone ways) used for translating a constant input into a non constant(intermittent) one. the most notable example of such a mechanism being used would be on a mechanical clock. you want the second hand to only tick once every second and don't want it to move constantly, both because it would make telling the time harder and also because it would cause the spring to loose it's tension very quickly and require constant rewinding. the secondary sliding piece that interacts with the smaller pins is simply a form of ratchet to prevent it from going out of alignment or spinning freely, notice how in the original 3d rendering it makes contact with the pin just as the main arm is releasing the large pin and vice versa. i'm trying to think of an analogy for it but the best i can think of would be how on a socket wrench there is a ratchet to stop it from going backwards the wrong way. but yeah, variations of this sort of gear are sometimes seen in either analogue clocks or large industrial mechanisms that require an intermittent movement for one reason or another. i recall seeing something similar to this on a very old printing machine where a long reel of paper was fed in, it would stay still long enough for the printing to take place and then move the paper to the next section to print again in a kind of jerky/stop-start motion.

The hug is there to prevent it from spinning when the driving arm is not connected. You don't have any load on the disc so nothing happens (and the speed appears "improved" when it derails), but imagine that was a wheel driving up a hill. As soon as the arm releases the pin, the wheel will immediately start rolling backwards since there is nothing to prevent it from doing so.

[@Frogly7]

You could use this on a mechanical clock, so that from a constantly spinning motor it will tick the minutes over one at a time. This way when it's half past the minute, you don't see the bottom half of 5 and the top half of 6. It will show 5 fully until it's time to tick over to 6.

Honestly I think the problem was that the yellow pin had a friction issue with the purple slider thingy I also believe it was that the yellow pin was on the wrong block so that is why it got the friction issue but the other pins didn’t because the yellow pin would be underneath the purple slider causing the friction issue and other pin weren’t because they were not underneath the purple slider while it was letting go of the pin to move and grab the purple pin For short: my theory is that the yellow was having the friction issue when the purple pin was in the spot to be grabbed

[@markjacobson4248]

I'm not sure if this has any name, but it looks like it would be significantly more compact than the Geneva mechanism, since the output wheel and input are aligned and very little extends past the edges. Additionally, the Geneva mechanism is primarily good with an output that has little load on it, because it has a pretty awful mechanical disadvantage with a much longer lever arm working against it than this mechanism does. Related to the mechanical advantage, the Geneva mechanism moves in an extremely jerky way, particularly with outputs with small numbers of steps

In case you are still wondering what this thing does: It provides constant periodical rotations up to 180 degree(exclusively) per cycle. The rotation angle is configured by distance between two pivots. And, yes, you fked it up - your rotation was not 72 degree per tick and that caused almost all your problems. To fix it, you need to place the outer pivot closer to the center.

The thing turns smooth circular motion into stepped circular motion. Every rotation becomes 5 ticks. A more complicated one of these could make a ticking second hand on a clock for example. Alternatively, this could be a REALLY rudimentary gear system that could be made with lower precision tools than real gears if smooth output motion isn't needed.

[@VesaKo]

I think the reason the purple failed is because it's a special part of the mechanism. Because all parts are on a grid, some consecutive pieces will have more distance between them. This is the most pronounced on the edges with two pins. The purple has the greatest distance in the entire mechanism between it and the pin let go by the guiding arm, causing it to be too short of the slot. When the speed was upped, the pins were turned farther by momentum. This made the purple pin work and all the other pins go a bit too far, causing slight issues with them.

It was interesting to see! :o I'm not sure because I only did a quick research (but still more than a Karen-level research I hope) to slightly confirm the thought I had, but this mechanism seems to be the base movement made to make steam locomotives roll on the rails. It's just that the steam engine (simplified like crazy) makes the yellow hugger piece move (I guess from steam pressure that forces the yellow piston to move back and forth). Your purple part would have in the situation more interactions with the wheels, because it would have two of them "connected". The throttling force generating enough inertia to ease the process, maybe? Maybe try to make the yellow piston move back and forth next time? I could be really interesting, I'm pretty sure. Because the videos showing mechanisms maybe lack the motor, the piece that actually triggers the contraption. It's not intended to, though. Just to show the movement.
