Bike com tração de ENGRENAGEM 3D

since we’ve already made a bicycle with a car toothed belt drive and a drive with a gate lock chain, so today is the day for us to make a bike with a gear instead of a chain And how we’re going to do it I don’t know I just know that I’m going to go looking for an old bicycle frame so I can start my project But I don’t know why but every time I go looking for a quarter bike it gives me the impression that they’re trying to run away from me But the first thing we’re going to do is get a grinder and give it a give it a good sanding because I was afraid to even look at it of getting tetanus from all the rust And you thought we were going to show it by assembling the bike again but this time we already have the bike assembled guys. I mean , the rear wheel is still missing , right ? At least that’s the intention, being able to do it is another thing. Even though I’ve never messed with this hub, I believe it will be easy to assemble. Let’s just put this and this and this and this and this and this and this. And our bikes are in the way where we can start making the support or our project itself, right? reinforced here Look, just so you can see how thick it is And the intention is for us to place it more or less like this and attach several and several gears to it เฮ So our art here is ready guys But now the real challenge, guys, is for us to be able to make the gears so that we can do the traction And if I tell you that we got a Ferrari for us to make these gears well, it’s not a real Ferrari but it’s considered a 3D printer Ferrari No even the packaging of the business has an absurd quality man It makes you want to save the packaging It makes you want to throw it away no man But right away we can start saying that it is one of the fastest printers there is Just to give you an idea a conventional printer prints at an average of 50 mm/second I have one that I have already presented to you that prints 100 mm/s so it is very fast This one prints nothing less than 500 mm/second Man, this business is absurd It’s as if it had comparing a Fiat uno not a fiat uno not a Beetle Comparing a Beetle and a Ferrari Like the Beetle will give you 100 km at most a Ferrari will give you almost 400 km but it comes with the AMS system that we’re going to take out of it here now With AMS we can put four rolls of filament so we can print with four colors at once And we can put three more but this way forming four so we can have 16 different colors man In other words, you don’t need to keep painting the parts after they leave the printer from here. It even just finished automatic calibration because it has an artificial intelligence system to do the automatic calibration. We don’t need to adjust the table by hand like others, man. And it doesn’t require any work for us to assemble it. It comes practically completely assembled. The only thing we did was remove some support due to transport, right, and we can do this installation here at AMS, connecting these little hoses from behind. But now that everything is in order for us to start printing our project, we just need to install the filaments But this printer here, folks, its model is from the brand Bambulab right so that when it comes to changing horns, it’s well aligned Man, look, you can see, did you recognize all the colors that I put there without us doing anything automatically Here through the panel we can make several adjustments here Here in this folder there is a folder that is full of models here that we just have to take and click and send the printer to print all at once But as we are going to make our exclusive project so we will have to go to the PC so we can make our drawing of our project Oh remember guys that this here is a professional tool to make money man This here is also for robotists but if you are interested man I will leave the links in the best way to buy here in the video description But then it was time to design our gear. I’m going to make the gear for the spark plug so that it will have 38 teeth and make some pattern marks in the middle so it doesn’t end up completely round. I’m going to make a 30 mm hole in the middle so we can fit the spark plug and make another smaller hole so we can fit that other ferrule for the spark plug that we’re going to use a monobloc sail foot. Give some modeling to the corner of it and export it to Bamboo Stúio, which is the original slicer from Bambu Lab And just send it to the printer to print And the good thing is that you don’t even need to keep filming because it has an internal camera that itself already films the entire timelapse inside it, man And look at the suit of our crown it’s big, hey, look so you can see But the size of it here is a strategy because this back part right here we have to remove everything here because it’s all the support Here there is a last layer of fillet here to remove to make it very smooth but I’m not going to make it smooth not too much because it will be hidden behind here Let’s take a 4.5 drill and drill five holes in our crown and take an M5 male and thread them all To assemble we will place the crown here from behind o And just come with these chamfered head screws so I already made the chamfer here so that the head of it can really fit there o And here it fits on the crown’s thread And after inserting the five screws and now tightening the head of the screws o it fits well Oh The other side like this And look for you to see guys There’s a thing that looks like it’s the same lathe service man Look for you to see The thing is very precise man Look for you to see o We put 30 mm there just right And look at the day that here Oh Man pressed man Pressed Look at it bro From the sky Very top man It’s even hard to fit o There’s no way it can’t be centered man Awesome show Now just assemble the normal candle foot And now we have it our crown means our gear, right? It means the crown mixed gear gives what the crowning gives And I just know it’s ready man Just for you to see man Great show bro Working the whole file oh But now we have to develop the gear that goes in the wheel hub So we started designing another gear with 19 teeth with a very large hole in the middle throw it in the hand of the printer and wait for it to be ready And our gear is ready We’re just going to remove this back part here which is the support too and we’re going to get a 3 mm drill and drill five holes in the pinion too and take an M4 male and make a thread in all of them And it will fit like this o We made the gear here of the correct model so it fits here in the pawn o It fit here o Justinho Ball show Now we just have to screw it o Dude, I’m very happy with the result man Look at it for you to see It’s very tight, too, man Ball show on the other side too, o 100% Hey, I fixed this one wheel here leaving only these little heads on the outside of the spoke I didn’t leave the knee because if I left the knee of the spoke outside it would take up more space and make it even more difficult for us to be able to get this project out there, But like this, man, it was a great show man You’re crazy I didn’t even think it was going to be that good, man There’s a curious thing about this hub that has a gear When you turn it backwards here , it turns falsely, right, like a ratchet But if you turn it forward, look at it you see what happens, you see, I turned it forward, the axle turns in reverse. If you don’t hold the axle, the wheel doesn’t turn, you see, so this axle has to be very, very fixed, really man. you see why it has to be locked properly because otherwise if it isn’t locked properly when you pedal the axle turns there and doesn’t pull the bike But now we’re going to chip the wheel in place But then the part of the spark plug and the wheel is already ready guys Now we have to insert the other gears that go here in the middle, right, until we attach it to the one at the back here But it’s not something as simple as the wall, just take the other gears and fit them here Guys, I made a sketch here I’ll show you for you to see, you just don’t notice the drawing because my 2 year old girl draws better than me But here is for you to understand, this big crown here, it will be rotating forwards But when one gear touches the other, the other one runs backwards It’s not like the chain is pulling that everything goes to one side When the gears touch, they rotate in reverse So this second one here will rotate in reverse, you see, then the third one here will rotate forwards again because it will be opposite this one The fourth one it also goes in the opposite direction, this one will rotate backwards The fifth one will rotate forwards The sixth one will rotate backwards And the seventh one will also rotate forwards So, did you notice here, this number one number 2 3 4 5 6 and 7 all here that are odd ones rotate forwards Look so you can see And the ones that are even ones rotate backwards in reverse So we have to put the amount of pulley there that will give the gears right, right that will work to turn the last one here forwards So we have to put either the fifth or the seventh because I want it to be more or less the right size here I don’t want to have one much bigger than the back or small So it has to be more or less all the same So we have to see this diagram of the right size to make everything work out like this man So in a magical way we developed three more gears with 16 teeth But here, I left this hole on the inside there with 13 mm and this one on the outside here with 22 mm because I have this bearing here with 22 mm and it has 7 mm like this So I made the cavity here with 7x 22 and we’re going to fit it here, and it fits in, pressed, very, very pressed. Cool Now, this bushing that I made here, I made it 12.5 m long so that it would be loose inside there, and a little wider, that inside part There, it’s 6 mm, I made it here with six, it’s 7 mm here, o So, it went through, at the top, like this, f in height, it went through, and here, in the diameter here, it got loose there, Now we come with the bearing and put it here because if we put the bearing with the screw pressing it without having a bushing in the middle so it doesn’t get stuck here, then we end up crushing the bearing and ruining it , but now we just put the screw in, man and it’s going to be great Man and with a rusty nail we’re going to drill the plate so we can screw the gears in well aligned Make the thread in all the holes and it even gives a light paint job to the whole bike which was all rusty Satisfactory moment in the video Can you believe that I can’t believe that I managed to make this project so 100% so perfect like this man And it turned out just right man Look for you to see, oh Justinho oh The little bit that moves there moves them all I put these tapes here so you can see exactly the direction of rotation that I was telling you o I turned it around forward, the second one is backwards, the third one is forwards, the fourth one is backwards and the fifth wheel is also forwards. Just look for you guys to see, Dude, what a great guy, this thing is enough to hypnotize the eyes of us looking at this thing, man. You’re crazy , really great. Now here, the gears are all going perfectly, right ? This time the thing worked great man You’re crazy The thing was too good But looking at it like this it gives the impression that on the first ride it looks like it’s going to break, it won’t hold, right guys just because it’s made of plastic but the thing is strong man But this personal project I did he’s learning along with you Man, I didn’t know anything about this 3D modeling business It’s about this printer too We’re all learning together. This is the detail that I did here later, I got the mothers to do it here in the Bambulab studio, man Why, if I had picked up these tricks before, man, I would have done some details here about other things, written something here, I don’t know, man, on this big gear But okay, we’re learning little by little But you But it’s already good, man You imagine our first project of 3D modeling I’ve already done something like this here, can you imagine the next ones, man? But I’m going to position the camera here and I’m going to show you the thing that’s happening here, man. Because this crown that we attach to our gear is warped, man. So it ‘s throwing our gear like this from one side to the other. Not by throwing it back and forth, it keeps rubbing against this one . Creque creque creque creque. very high resolution it keeps scraping here Look, just so you can see, When you pedal it keeps going from one side to the other Oh, you see, but here, when we’re pedaling here, testing it here, it doesn’t seem like there’s practically any noise, but when we pedal and apply force, it keeps scraping from one side to the other. So I believe that here we would have to either change this crown here, right, put one in place, we could have bought the new one Or we could file these teeth like this so that the teeth look good. smooth to crack there and nothing is going to happen Now I don’t know if we could put some grease on it too Could we put some grease on it man or maybe some silicone some Vaseline Let’s go for a walk then guys Oh rep Oh the little noise What does it do the more force it makes the more noise it makes Now I’m pushing with no o No noise Oh second gear there o You forced another cal Go third gear Dude everything is working fine man The gears o Fourth gear It’s Fifth gear now Wow train huh that’s it There was no engine, man, it’s a real show, man So, it’s making almost no noise, right, fourth gear But here to solve this little noise there, man, is to actually change that iron crown that we attached to it because it’s a little bent, but it’s really great, man This thing is making waves Everyone who passes by, man, we don’t keep filming because sometimes people get embarrassed, but everyone who passes by, man, looks like that Oh my God, what is this, too top, man But let’s do the following guys, Let’s do a speed test like this and see how much that we can pedal how many kilometers that we can do with it pedaling man Let’s go I’m going to put the GPS here, the cell phone with GPS to mark the speed Let’s do a test of this for us to see Will it hold up guys for us to do this speed test will it hold up for us to push it let’s go Oh it’s first gear Let’s go Oh second third Fourth Thursday Weighed see the legs won’t go anymore You’re crazy 35 per hour The legs won’t let us anymore The cars that were good with their legs will laugh in my face I know Oh, but it’s no longer possible , man, You’re crazy, But it’s good, man, I put a lot of force here, man, It reached 35 per oh It must have actually reached about 40 because GPS always throws it down But it’s great, man, It passed the test, man, It held up, man, You ‘re crazy Let’s do an extreme strength test here now, guys, so we can see if it’s going to break. my weight here, Oh, there, Oh, man, Don’t break it, I can handle our weight here, Oh, Man, Oh, I’m going to brake here, Oh, I’m going to brake here now, Show me from there, from here, right here, Just like that, I’m going to brake here now, It did it when I’m going up the hill, I’m going to put the weight here, Oh, Don’t break it, man, What a great man, Talk to you, man, This plastic thing has too much strength, man, You’re crazy You guys believe me I honestly thought that this video would be one of those where we do the project, it looks cute but it doesn’t work but this time I was wrong but I was really wrong guys The thing worked more perfectly guys It’s a shame for us to dismantle the project man I’m even going to leave it there in the description of the video and all the files there for anyone who wants to download so they can do the project there Hey man if you want to tag us on Instagram take a photo there and make a little video even imagine a project like this here at the science fair for those who are students Dude I think I think the guy got an 11 out of 10, man, it was really top, man But what about you, did you like our little project this time in our personal video, I think there was a lot of information like that in this video, very different, didn’t you guys, hey, if you liked it man, put it in the comments and let me know if you liked it if you didn’t because boy, I’m going to talk to you, I liked working with this thing, man, you can do a lot of interesting things, man, you can invent a lot of cool things, see, but let’s thank Bambulab a lot, guys, for having us sent this top 3D printer for us to be making this video, man Hey, guys, one thing I didn’t tell you is that the machine is it, man, it’s so smart that it even has a thing there that’s a humidity sensor for the filament. If the filament is damp, it tells you that the filament is damp and you need to change it . And man, a very interesting thing is about automatic lubrication, man. lubrication, the shaft needs lubrication” But you’re going to use grease, there’s even a little kit there with grease there for us. I think these things are very top-notch, these automated things. And another thing that I didn’t mention personally was when you’re going to print with it in different colors, it has this function, it discards the filament. When I go to change the color, it discards the filament waste because it’s a normal thing because otherwise, if it doesn’t do this, it doesn’t clean the nozzle that was used with the other color, you know, and it ends up getting stained. the piece So to avoid staining the piece, she disposes of it there, cleaning the nozzle first before adding another color. There’s even an app called Brambo Rand that we can download and get the ready-made models there , there’s a lot of stuff. People put a lot of cool stuff in. And look, you can see what I put there and I put it down there, right, and printed it. for you to see, But it goes up and down, lowers and goes up, right, man Really cool, man This stuff here is really great, I made this spatula here too, Look, just so you can see the finish there, man, Really cool , right? We’re going to stop here guys If I’m going to talk about all the features this printer has, we’re going to spend about two hours talking I even made a little post here, my girls have already done it already, but then guys, here’s the thing, I’m just going to talk to you if you liked the video, man, leave a like, subscribe to the channel and put more challenges for us there because we’re going to make some more videos on the printer, man Tell you, a few more top videos, but it has to be top stuff. We’re not going to keep making the boring little printer video. no Let’s do this from here on out man It just has to be something absurd It’s an absurd project man 3D Printing So guys I hope you enjoyed it and see you in the next video, God willing, follow us on social media, everything there I want to see you there Alright wow So you can have an idea
