I really appreciate these videos with your practical applications to real world situations. Having farmed in the midwest US for many years I sometimes applied the same techniques (such as shortening a bolt, or using a screw driver as a punch) in our farm "shop". At this time however I especially appreciate the Fusion techniques you're showing as I am quite a novice in this CAD program.

I love the jig you made to center the hole. If I may make a suggestion, you might want to enlarge the botton hole. On the top of the jig, you add a large round hole. You then can print a plug for that top hole with an appropriately sized hole in the plug. These plugs would be interchangeable and potentially single use, but it's easy and cheap to print them as required.

@antalz 4 жыл бұрын

Thanks! The interchangable plug idea is pretty good, that would cut down on the reprints by quite a lot. You would need some method of securing those plugs to the rest of the jig though, but that shouldn't be too hard. Another option is to use drill bushings, as I've shown here: kzfaq.info/get/bejne/p8t0aqd93qfcZ2g.html

I enjoyed that. It was good to see the design taken through to the finished article including printing tips and then how to improve it. I just want to throw in a few things. At 1:30, when running the "Spur Gear" script, go to the "Add-ins" tab instead. Run the "Spur Gear" script from there, either the C++ or Python version (most tutorials seem to prefer the Python version). The script will now run until you exit Fusion 360. You will find Spur Gear at the bottom of the "Create" drop-down list in the "Solid" tab. 11:00, you can right click on individual components in the "Browser" to save as STL. You can use this method to save individual bodies within components as well. 20:54 At Last, I now understand how and why to use "Project". Thank you. At 22:15, you mirror the screw and nut features so that you can add a screw from the opposite side. Meaning that your shaft had a flat side, will this throw the centre off?

@antalz 3 жыл бұрын

1:30 I know that works, yet I never do it that way for some reason. I probably should because it saves a few clicks. Strangely I can't get the add-in to run at startup 11:00 Another button that I know is there, but that I never use for some reason. Old habits die hard I suppose. 22:15 If you torque the screws down equally hard, they will push the gear out equally hard. The nuts also have exactly the same amount of plastic they can push against. The only difference is that the setscrew pushing into the flat will be slightly closer to the center, causing a slight mass imbalance, but that's really tiny. Make sure you torque both screws down in a roughly equal amount though. Thanks for watching so attentively!

@slimknight_ 4 жыл бұрын

Amazing video! I couldn't figure out how to get to, let alone use the gear extension. You might want to consider simply printing a gear with a 'D' shaped hole to fit the shaft Also right clicking the body or component will allow you to convert it to stl which is slightly easier

@antalz 4 жыл бұрын

I haven't ever tried printing a D shaped hole, I pretty much assume that it won't hold up to the torque. A generic stepper with a 5mm D-shaft produces 0.5Nm, that's 0.5/0.0025 = 200N of tangential force right at the shaft's edge. I just always assumed that such a force concentrated at the corner of a D-shaft hole wasn't going to work. Perhaps it will and I'm just being too pessimistic about it. Good tip on rightclicking bodies/components, I hadn't seen that before

@@antalz I will say I don't believe Creo has the same kind of convenient intuitive tool that Fusion 360 has as you're showing, though I am pretty much brand new to Creo. What I've been doing so far is manually creating the involute curves (like how you'd have to do one with pencil & paper) using the steps described in the textbook Shigley's Mechanical Engineering Design, chapter 13; I know that you can also generate the curve by inputting the parametric equation describing it but for now, I find it a little more fun and satisfying to do the pencil & paper process; lot better feel for the gear geometry this way.

Thanks for the informative video! What filaments do you recommend to print the gears in? My preference goes out to ASA (instead of ABS), but i saw better performance of PLA in some videos. While often stated that PLA should only be used for visual prints. I like to hear your thoughts!

@antalz 2 жыл бұрын

Most of my gears are PLA. PLA has better stiffness, and can resist higher forces, than most other filaments. Its only downside for gears is the low temperature resistance, which is a problem for high speed gearsets. PLA is definitely not just for visual prints.

@marcdraco2189 3 жыл бұрын

Brilliant. We were taught (many years ago) that a metal screw with a shaft as you showed here is a bolt, not a screw. A screw has threads all the way to the head.

@antalz 3 жыл бұрын

There are unfortunately many different opinions on this matter. The one followed by the machinery's handbook for example is that it's a bolt when you put it through a hole and put a nut on the other side, and it's a screw if the hole itself is threaded or the screw cuts its own threads. I dislike this definition a lot because it implies that what a thing is (screw or bolt) depends on how you use it, which seems silly and pointless to me. But that's just to illustrate there are tons of different viewpoints about this. Personally I tend to call small stuff screws, M6 and under, and larger stuff bolts. This too is a very arbitrary and meaningless distinction. I am also more inclined to call something a bolt when it has an external hex head, for use with a wrench. At the end of the day I recommend just not worrying about it.

@antalz 4 жыл бұрын

Thanks! I think that won't work, it's sortof like pulling yourself up by the bootstraps. If the screw head is pushing the washer back in by let's say 10N, then that's 10N less force of the screw tip pushing into the shaft. I feel like I should think about this more, there must be a better way to explain this.

@@antalz Yes I understand what you mean, the force would cancel out. I was thinking the screw head couldn't move the nut back down the thread but that doesn't matter, it's not where the force is coming from.

Nice lesson! Extruding rectangle for a nut is unnecessary action, cause later you anyway draw a poligon on a new scetch. Faster and easier is create an offset plane (or tangent plane for the compact gear from the video) and draw a poligon for a nut and a circle for a screw there

My hope is that this will be a layman's guide to designing decent and useful gears that's easy to understand. I don't need perfection, I'm not building a transmission. How does one decide how many teeth there should be? When should I use a bunch of small teeth, when should I use fewer big teeth, etc.

@antalz 4 жыл бұрын

That's what I'm currently aiming for. I'm currently trying to balance depth with complexity. My current idea is to use basic algebra to discuss number of teeth, size of teeth and shaft-to-shaft distance, and one line of elementary trigonometry for pressure angle. I don't want to talk about what pressure angle does to the shape of a tooth, I don't think people care, but I do want to show that spur gears push each other away while transfering torque. I definitely don't want to get into elaborate geometrical constructions or any integrals.

@antalz 3 жыл бұрын

Yeah I did consider Nylon. It should be quite good with a quite low friction. I do expect the teeth to warp, so I think a raft would be in order. I don't know if I can test how different materials compare when it comes to gears. I didn't do Nylon for this video because I don't want to make the subject more daunting. Nylon is quite hard to print, some Taulman blends are okay but true Nylon is quite hard, you need an all-metal hotend, enclosure and good moisture control. I do have a printer set up for it.

Thanks for sharing your tricks with fusion 360. For the screw you cut at the end of your video, grab its head with your drill and make it rotate (lowest speed) while creating a chamfer on the cut end with a rotary tool (mid speed) with little cutting disk. Use the face of the cutting disk and just touch the burred cut border. Take your time, those little cutting disk are fragile when used in this direction.

@antalz 6 ай бұрын

That sounds like a good trick, though does that mean you have to keep two tools running simultaneously? Or should you put the screw into the drillpress?

@rufo4004 6 ай бұрын

@@antalz Yes, you have to keep two tools running simultaneously. A drill press also works. Adding several nuts tightened to the head side will help in securing the screw to the drill (or drill press) so the head and the nuts are tightened together in the chuck. Do not forget the safety glasses. The screw in a drill (high speed) and a file will also works, but in my experience the rotary tool will provide better results. I also use this method to reduce the diameter of the head for tight locations. Hope this help.

@jeremyhicks6889 2 жыл бұрын

Late to the party, but as an engineer, I feel the need to comment. Gears need 100% infill. Yes, in general, material stresses run higher on the surface, but effectively having a hollow part creates surfaces on the inside as well. The sharp inside corner that the slicer will leave under each tooth combined with the inside corner created by the inside surface of the face will create sharp junction of three surfaces on the inside. This will be a huge stress concentrator. Use 100% infill. Also try setting the top/bottom surface thickness to the full thickness of the gear. I would expect that the diagonalized print lines of the top/bottom layer will act to brace the teeth. Also, I would experiment with the shell thickness. I would expect that would allow the diagonal lines to extend into the tooth somewhat, preventing the delamination/crazing at the root of the tooth.

@antalz 2 жыл бұрын

I don't think I agree entirely. You are correct about the stress risers in general, but if you ensure that the shell thickness is large compared to the width of the teeth, the "inside" surface becomes nearly cylindrical. Still it's a great basis for experiments, though at the moment I don't have a good test setup for testing gears.

Any strategies for those of us who don’t have Fusion 360? Great tutorial though. Thanks for taking time to show us. Doug

You can get Fusion360 with a free hobbyist license, but it has some limitations that I don't get with my pro license. You can try it out and see if it's still good for you. There is also Siemens Solid Edge community edition, but I haven't tried that myself. Finally there is FreeCAD, which is free and open source. I believe it's quite feature-complete, but it's a difficult program to learn I found, and there weren't too many tutorials about it when I used it years ago. That should be much better now though.

Simply amazing video ! I have a question please, do you think a carbon fiber nylon gear would hold if it was connected to a 32cc 3hp rc engine ?

@antalz 3 жыл бұрын

Thanks! Unfortunately I can't quite answer that question. The first thing you want to figure out is what module and number of teeth you're thinking about. The module determines how large the teeth are, and larger teeth can bear more force. The second thing is that you mainly want to look at torque, so it'd be better if you know how much torque the engine will produce. In video 2 I also discuss that the Pitch Diameter = module*(number of teeth). So what you want to do is Force = torque/radius, to find out how much force a single tooth will have to hold. Once you know that you can start looking into material strengths and whatnot. If you want to really get into it then you have to take a look at the Lewis bending equation, but you can also get a decent idea with a stress analysis. The other thing you can do is just try it, perhaps even with a PLA gear. If the PLA gear instantly shatters you have a problem, if it holds for a little while before it melts you might have something you can work with. I recommend checking out video 2, it has some of the maths and concepts you'll need to find an answer to your question: kzfaq.info/get/bejne/pc1zetRixrmxaGQ.html I wish I had an easier answer for you

@@antalz thank you so much for the reply ! I see what you mean i will follow your advice, torque is know in datasheet i dont remember i have to check the datasheet and the number of teeth is 38 because i am copying a metal gear which i am buying from the market, btw do you think a simulation can be done for a 3d printed gear ?

@antalz 3 жыл бұрын

@@Firashelou Yeah I'm pretty sure it can be, but I actually refrained from suggesting it because stress simulation will be removed for free Fusion360 users sometime soon. But if you have access to static stress simulation, you can slightly flatten an area around the pitch circle, which is where the force is transmitted, then apply the force to that slightly flattened area, then do a stress analysis. You do need to know the module before you can do that of course. I think that, because the force is entirely within layer lines, you don't have to worry about the anisotropy.

@antalz 3 жыл бұрын

@@Firashelou You'd get that from the datasheet from your filament vendor usually. For PLA you usually have around 50 MPa break stress. CNC Kitchen here on KZfaq also has some videos on testing filaments.

If you’re going to go to the trouble of mirroring everything to put an additional setscrew in, which pushed the piece away from the driveshaft, wouldn’t it be better to design it so it actually clamps on to the D shaft?

@antalz 3 жыл бұрын

I haven't really found a great way to do that. I don't think you can print an accurate enough D-shaped hole so that the gear goes on without excessive force, but also is locked to the shaft well enough that it can withstand 2-3 Nm worth of torque. If you have a more sophisticated design idea I'd like to learn more.

How can I achieve clutch mechanism in 3D printed parts? Please help! I want to develop a mechanism (positive drive preferable) that engage or disengages the motor shaft from another stationary shaft.

@antalz 3 жыл бұрын

I don't think I have a good solution for this. The best ideas I have are: 1) Put a crown gear-like thing on both shafts. You can then engage/disengage it, but the transition will be very sudden, it will create a pretty intense shock 2) Make a ring of magnets on both shafts. When far apart they won't transfer torque, but they will if you bring both rings close together. This doesn't transfer that much torque though even with strong neodymium magnets. The final idea is using a planetary gearset, and then applying/releasing a brake from one of the gears. I haven't explored this though and it's quite complicated. I don't know of anything that would really replace a true clutch.

Sir which one is better material for gears Nylon or Teflon From all point of view like strength, friction, durability, etc

@antalz 3 жыл бұрын

I'm not completely sure, but I think Nylon due to better stiffness. Friction and wear resistance are very good on both. Are you planning on cutting your gears from a blank? I believe 3D printing PTFE or Teflon is impossible to begin with.
