Fusion 360 Tutorial: Modelling Crown Face Gear

[@TRCFL]

I was so impressed when I hit OK on the circular pattern and the resulting gear geometry was perfect. Been trying to figure this out for a week and your video was spot on to what I needed to do. Thanks so much. Now its time to tackle a worm gear.

Thanks Chris for those encouraging words..Good luck with the worm gear..A small suggestion, if u find the two gears interfere..Increase the centre distance or else incorporate some clearance..

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!

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

[@Oggies100]

Great tutorial, easy to follow, thanks for taking the time

[@saikishoret99]

Thanks Mark..Hope this is useful to you..

[@BurkeDEV]

Great tutorial, thanks!

[@jackberriman9530]

Great video - very informative! Although, in the description you have suggested that rack teeth will cause considerable error - why is this?

[@danakelley2535]

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.

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

[@PichanPerkele]

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?

[@JohnYu-y9t]

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.

[@joefalvo8339]

Awesome video! Thank you for explaining how each parameter is defined. Can you explain how to create an involute spur pinion that will properly mesh with this gear? Thank you.

[@saikishoret99]

Thanks.....and check out this video..kzbin.info/www/bejne/iojKe418jLWaitU, It involves creating a spur gear from a Involute curve...and for meshing you can Rotate/Move after modelling..We also need to give some clearances to account for Interference....you can message me if this is not what you asked..

[@potionpi747]

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.

[@beniaminbaciu4456]

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

[@Jungmin_Seo]

Thank you so much! really helpful tutorial.

[@mihailazar2487]

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

[@mattzera1]

What are the benefits of using a crown gear over a normal bevel gear.... I've been looking online but i couldn't find anything

[@saikishoret99]

We can use spur gear to mesh with crown gear.. I am not sure it is acceptable in high load applications..but this configuration is heavily used in toys and low load applications

[@calebburgess94]

Do you have any advice on generating an epicycloidal tooth flank profile to make this face gear model a functional prototype?

[@saikishoret99]

Sorry Caleb, I am not sure at this moment but I will let you know if I find anything

[@AncientMantis]

Brilliant

[@danakelley2535]

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