Thank you for this video. It helped me understand several aspects. I wish to create a hypoid spiral and the basic principles are hard to grasp. This helped a lot.

[@peteredwards2371]

Hi, I’ve read the various comments below and I already knew that your design was not engineered correctly to be a true gear but, for all those who don’t like it, remember this was stated in the video and reference was made to documentation detailing how to calculate all the relevant data. I learned a great deal from this and your other videos on how to use Fusion to create these parts. With the knowledge gained here, I am now able to design and draw several types of gear assemblies for which I am very grateful.

[@Fusion360NewbiesPlus]

Hi Peter, You are 100% correct. My videos are about the techniques you can use to achieve your goals even though F360 don't have the specific tools for them. I'm glad you noticed that and that my videos helped you :) Cheers / Ben

@@Fusion360NewbiesPlus I've been doing CAD for 30yrs and understood that this was only to pass on info about how basic graphic representation and Motion is and can be done in Fusion, not to be confused with Engineering param. Good job Peter

[@mroek]

Interesting technique. It seems kind of an ad-hoc method that doesn't take into account all of the special equations and methods of creating gears (like involutes, pressure angles and such), so I'd be inclined to believe that this method isn't suitable for machined gears or gears that need to be very accurate and/or silent and/or durable. However, for 3D-printing that probably doesn't matter, so I'll definitely look into your method some more. Thanks for taking the time to create this, I think it will be useful! :-) Edit: I took a look at your file, and as I suspected, the gears don't really mesh correctly. Try adding a section analysis that cuts the area where the teeth mesh, and then rotate, and you'll see that there is a rather significant overlap between the teeth in some areas. If the gears/teeth were correct, then the clearance would be constant at all times during the rotation. However, for 3D-printing (at least FDM) this will still probably work fine, due to the not-so-great precision of th printing process.

[@Fusion360NewbiesPlus]

Just change the clearance (maybe the profile as well) and everything will be just fine. You should focus on the technique and not the measurements! If you need help, please let me know.

[@mroek]

Yes, of course it is possible to change the clearance, but that's besides my point. My point was that this technique does not create what could be thought of as a "correct" gear mesh. Increasing the clearance is just a way to camouflage the error. But again, I'm not saying this method isn't suitable for 3D-printed gears, because I'm certain that it is.

[@gusbisbal9803]

You are correct sir. This is a case of a designer producing something that he doesn't have to manufacture. If he was CNC milling this then HE would be having to fit the two together and saying,"Shit, I screwed this up" These are models that look like gears instead of engineering that you built in CAD. If you want to BUILD helivcal bevel gears this is not a valid technique.

[@Fusion360NewbiesPlus]

The bedst way to know if it's a valid technique or not, is to try it. This guy used the same technique, but for a Worm Gear and it worked for him. Maybe it worked for him because he printed it. Unfortunately, No body gave me a feedback in regards to a CNC yet! forums.autodesk.com/t5/design-validate-document/help-the-best-way-to-construct-a-worm-gear/m-p/6997880#M106517

[@marianosihuen1470]

mroek do you know any software to generate real gears?

[@BlaiseBarrette]

In the "Motion link" dialogue box, you can simply enter the gear number for ratio instead of doing the calculation. 21 for the large one and 12 for the small one. Fusion will take care of the rest! Thanks for you work!

[@Fusion360NewbiesPlus]

Great idea, thank you for sharing!

[@akshayd211]

Thank you Dudes! 8)

[@OCDRex11]

Can you explain this more please? I open the dialogue box and only see rotational values and changing those is only the rotation not size. I know your comment is 6 years old but hey, worth a try!

[@dfergenson]

Thanks for a great tutorial and for providing the source files.It's a huge help. I noticed a couple of things. First, the trailing end of the teeth interfere with each other as I turn your example drawing. This can be manually accounted for but it may also fixed by using the math that mroek mentioned. If I get a handle on that math, I'll post some pointers here. Otherwise, if anyone does know enough about it to post here, I'd greatly appreciate it. Second, a more reliable way of creating a tangent plain for the gear teeth to be engraved into/protrude from is to use the initial sketch and then construct a plan at an angle from the line that intersects the two faces. That way, the teeth are always centered on both parts. Thanks again for an excellent tutorial.

Hey Andreas, I'm glad I could help :) Please contact me at [e-mail] - I have a question to ask you!

[@Fusion360NewbiesPlus]

thanks for the feedback. We are about to release a new platform that will help users to buy a new hardware for their software, and we're looking for Fusion 360 users like yourself. Would you be interested to be a tester?

[@mccunnj]

Awesome! Thanks, very insightful! FYI, the gears and ratios link seems to link to a page that doesn't show calculations....

[@lolaa2200]

Nice way to create something that looks like bevel gear. But those are not proper functional gear. The teeth profile can not be "however you want" if you want a gear that mechanically perform correctly. So for me that's only suitable for decorative object, not for mechanics.

[@gauravmathur4940]

this is amazing ! thanks

[@bushcraft-thijs-bod]

It looks like the gear teeth are intertwining at the edges, at various times they collide. Other than that a nice video, but I don't think this will run smoothly in practice.

[@bikramdeb8459]

Please make more videos this will help us

[@anandhuviswanath2726]

Thanks alot.

[@alexw8753]

Thanks for sharing souce file and for all you time whit this! I think you are doing a really good job whit this video, strait and clean explaining and understandable english :) I really like your methods in Fusion:360 is easy to use and fast to manipulate (few steps) There is room for improvement!. hope you don't mind, me being hornest, but whitout calculations of the gear radius/teeth, circular pitch/tooth thickness etc. its just pixel's Would be really nice if you had some more details on the theoretical side of crafting gear's mathematically correct formulas for the diffence gears.. Anyway thanks again.. you rock !! :)

[@Fusion360NewbiesPlus]

Hey Alex, Thanks for your feedback, especially for the constructive feedback which I really appreciate! There is a good reason for, why some of my videos are not detailed enough. The goal for my videos and this channel is to tech technics and to help people think more creatively and out of the box. If I'll go into details, people will focus on how to create that specific model and forget about the technic. Moreover, I'm more of a designer than an engineer and getting into the math aspect of gears, I'll prefer to leave it for the experts! BTW, Stay tuned, - very soon I'm coming out with some really exciting news. Something that will help to solve a HUGE problem for people in our Software industry and general media ;) I'll probably need some great guys like yourself to run the first test and I hope you don't mind me contacting you some time in the near future.

[@Fusion360NewbiesPlus]

Hi Alex, How's your F360 project is doing? Please send me an email to [e-mail], subject "New Project". I'm working on a new Platform and I would like your opinion on it. Thanks.

[@daveincaol]

I was frustrated when trying to animate the model. The video was made using the earlier version of Fusion 360. I've replayed the video so many times but cannot see the menus and labels clearly enough to work out how to complete the task. I've created .stl files and will carry out a practical test of the bevel gear after printing.

[@Fusion360NewbiesPlus]

Does the printed parts work?

[@daveincaol]

Sorry for the delayed reply. As I recall the model was too large for me to consider printing. I'll look through my files and try to remember to reply.

thanks for ur kind reply. i have already done the forum, and got a solution. thanks again.

[@Fusion360NewbiesPlus]

I'm glad to hear that!

[@dfergenson]

Well, as promised I'm reporting back on the math and I have some good news and some bad news. * Having read up on involutes (those are the shapes of meshing gear teeth) I can report that, unfortunately, they are mathematically fairly complicated. * Fortunately, good tools exist to automatically create them. Here's a good example: www.otvinta.com/tutorial03.html. * Unfortunately, Fusion 360 doesn't allow mathematical functions to draw sketch lines. According to the Fusion forums, this is a planned future feature. * Fortunately, you can use a freeware application called Blender to design the gears and then export a .STEP that you can import to Fusion. Details about Blender are found in the Otvinta link above. *Unfortunately, Blender is pretty complicated unto itself but, fortunately, it's power seems to be worth the effort to learn. So, the bottom line is: keep an eye out for the addition of mathematically-determined sketch lines in Fusion 360 and, as a stop gap, use the link above to draw your gears in Blender and export/import them into Fusion 360 and then animate them as described in this video.

[@Fusion360NewbiesPlus]

Hey David, Yes I know about the Otvinta website. As you mentioned, Helical Bevel Gear are not easy to make even in Blender! But, if the Helical Bevel Gear that you need doesn't have to be 100% mathematically correct, then you can use my technique. I know it's working, because someone has tried it and it worked for him. I'm sure Fusion 360 one day will have Helical Bevel Gear feature, but until then, we will have to figure out our self how to do it according to our needs. Cheers.

DO NOT USE THIS TECHNIQUE - THIS IS AD-HOC BAD ENGINEERING AND WILL ALMOST NEVER MESH CORRECTLY. YOU WILL WASTE TIME, MATERIAL, AND HAVE TO UNLEARN EVERYTHING HERE

[@comageist2463]

Great video! Thank you for posting. I was wondering if you have tried an off-set hypoid gear set? I am trying to model a Ford differential and can't seem to create a proper hypoid pinion gear that has both a conic shape and a spiral tooth pattern that will then mesh up nicely with a ring/crown gear. I watched your video on the worm gears and tried to combine the two concepts, but with little success. You can find me on Instagram @comageist if you want to see what I have going on so far. Thank you!

[@Fusion360NewbiesPlus]

Hey Chris, Thanks for the feedback. I have to admit, this is a very interesting challenge. Could you please send me a link to the exact hypoid gear you are tying to create? I have checked you Instagram and you have got some really cool stuff! Good job :) Cheers.
