This is a very similar approach. We have specialized software that can create precise 3D model files and process them with high precision. Suitable for fields such as models, robots, fishing gear, helicopters, etc.

Waiting for part 2 for 5 years

Great tutorial, thanks!

It's so kind of you to share such a nice video

The gear is not done yet, the upside shape of the theet should look as a trapez with the imaginary intersection of the unparalleled sides of the trapez, faced to outside of the gear

Hi we are facing some difficulties in fusion 360 and we are hoping you would help us out

where is part 2

If you make the loft towards the center, wouldn't the teeth become tighter on the inside and not mesh properly? My first instinct is to draw the tooth with correct dimensions on the inner circle and project the other side away from center on the outer circle. Am I wrong?

This video served me well, mainly by helping to jump-start my skills in Fusion 360. Looking at boring lessons never work Your video differs since this info is very useful (IMO), and is unique in providing something that doesn't really exist out there in KZbin land. Keep up the great work and Thanks!

could you please help me where I should change this process to design 30deg flat root Involute spline gear. I will be very grateful. btw love your videos

I tried to mess spur gear with crown gear but not get success, teeth inspecting to each other how to slove it

This will only roll against another flat rack if you want to make it mesh against another spur gear ... you're kinda screwed as the geometry gets crazy complicated in a hurry

I love the simplicity of the method .. every other tutorial uses some script or spreadsheet ..

awesome thank you, best fusion bevel gear tutorial

Hi, interesting video, thanks for sharing. How would you model a spiral bevel gear? I mean not lofting the profile along a straight line but along a curved one? Thank you!

I love your video (I slowed it down on the Laptop and followed along). I struggled for a long time on this one as I just could not get the Equivalent Spur to line up with the first....then I saw it! At 5:47 your slide says that the first of the three circles created has a Radius as BackConeRad but when you entered the formula you entered BackConeRad*2...now works fine. It was honestly killing me as I just could not get my Equivalent gear to line up to the use for the Loft. Thanks again.

I discovered why the below results were realized. My mistake. Once fixed the results were on target

Thanks for doing this youtube... It is a very good approximation to get started making this type of gear and helps one understand. There is a slight error result when using 360 Degrees/(4*teeth) to set the PD width. Once implemented the Measured results showed a difference in the material left in the gear, which should be the profile upside down. They were off enough to effect results. Instead of this method I drew the tooth profile in a similar way except diverged in dimensional technique. As follows Addendum + Dedendum = total space taken by a tooth plus it's negative AD = Addendum + Dedendum = Pitch Diameter * Pi / Tooth Count In drawing the tooth profile draw a construction line where the Addendum line will be. Make it equal to AD. Draw an approximate Addendum Line, AL, on top of construction line. Draw another line from the AL to AD end. This segment equals the Dedendum line length. Set this segment and Dedendum equal. The AL will self calculate. This resulted in positive & negative teeth being equal. I cannot say why the other technique did not work. My gear is small and has small teeth and is subject to jamming with minor errors. This video got me going in the right direction resulting in experimenting with tooth profiles. Eventually figuring out a good method for approximating decent tooth profiles for straight crown and beveled gears.

finally someone showing the maths of it, thank you very much!

Thank you so much for taking the time to do this. You've just clearly and concisely furnished me with the information I've been struggling to find, that my lecturers had failed to provide - actual lifesaver <3

If you take it the full 90 degs for the generation of the involute curve, you can use this to generate any gear shape (even non-standard, non-meshing gears). Very useful.

Why is base circle diam = pitch circle diam * cos(20)? Is it not simply pitch circle diam - 2 x module? Edit. I apologize. I realize now that your base circle is the circle for generating the involute and takes the pressure angle into account.

DAMN!!! Wish I had thought of this method. Can be done in other non parametric CAD too. Thanks very much for the idea.

I worked it at the slowest speed and managed to make my own sized wheel and pinion, owe you a drink, thank you so much, phew a long day that one :-)

I noticed that you're using a simpler approach for the involute here (compared to the spur gear video), using an arc and tangents instead of projecting the involute from the base circle. It's a far simpler method here, which is great, but is it as accurate as the other method? Also, could you explain a bit more why it is that the 1/4 of the tooth angle dimension (at 1:23) works? Also, many thanks for making these videos!! I think these are the only tutorials that explain how to actually draw the involute. All the others are just walkthroughs on how to install and use the existing addins. :P Cheers

How did you create the joints?

That's way too fast to follow, even if you freeze frame it, you can't see what's being written.

Wow! Serious use!

Thanks this is a fantastic tutorial. I'd been beating my head against a wall trying to figure out how to build exactly this type of model.

hard work bro

sir what is d16 and d38

Thanks @Kishore for this video. Similar to @AbartG I noticed that after I rotated the second gear in place, fusion calculates an interference between both gears. I know too little about bevel gears but correct me if I am wrong: Shouldn't mathematical perfect gears to mesh perfectly?

I'm sure its good content, but it races so fast that I've spent more time rewinding than learning :(

Thank you for this video. Very helpful!

Very useful, but where does the pressure angle come in, or am I missing something.

Anyone else noticed gears modeled this way intersect each other? Or am I doing something wrong?

Thank you so much! really helpful tutorial.

I realize this is an old video. Can you provide the source of the formulas you used in defining the parameters used in this video?

Can you explain how the parameters you used affect the model? If I wanted to make smaller gears, what dimensions do I change? Can you show how to make a joint between the 2 gears so they move together?

Please! Please! Please! Before creating a sketch in a tutorial, go through the preferences so we can set ours to be the same as yours. That way, we see on our Fusion window, the same thing you show in the tutorial, as far as the orientation is concerned.As far as speed, record at a slower pace, let the user speed up or slow down the video as they feel necessary.

For all that have problems following this video for it speed, just set the video at 0.25 speed :-D and mute it :-D !! You welcome !! btw this was more a showoff than a tut lol but i like it!!! thx man.

This is one of the best and most accurate demonstrations of the true involute gear profile that I've found on youtube. Great job and thank you!

Thanks, this is a new knowledge for my company

Exellent video. You realy need to make an app for this. And you deserve more views too.

Thanks so much for the tutorial!! This one and the spur gear one! How do you make crown gears and a spur gear that fit together though? I can't tell if this gear fits with the spur gear tutorial and I'm not sure what it is that allows gears to fit together.

I am also starting a manufacturing of 3d printed plaster can we chat ??

Why is the base circumference equal to Pi * Pitch Diameter * cos(20)? I don't get the cosine part.

the video is way to fast.. and there is parts where there is only a frame of info, it is amazing to watch the video but useless to me sorry, just need to find another way to do the grears

Terrible - it is too fast for the beginner. The method is very good. Please make a slow video in 2 parts. Thanks

it won’t let me write pitchdia
