Parameter Based Hirth Joint in Fusion 360 | DOWNLOAD | How To Design A Hirth Joint

[@alan5171]

Thank you again. I didn't realise how powerful the parameters are. Will be having a look into how to use them in my future drawings.

Glad it was helpful!

Thanks so much for this video! I'm struggling to figure out how to fill that gap you discussed at 28:20 between the teeth and the revolved body. Any input would be much appreciated.

[@LearnEverythingAboutDesign]

at 26:34 we show the revolve to "connect" the teeth. What we could do is make the upper edge of that profile higher so that it fills in the gaps. The other thing we could do is with the triangle profile for the loft we could add a square section on the bottom of it so that the profile in the end overlaps the one next to it.

[@bradcavallaro4829]

@@LearnEverythingAboutDesign Awa I see. I hadn't thought about adding a square section to the triangle loft. Thanks so much!

Are both sides (or pieces) of the hirth joint identical? If you created a duplicate of that and tried marry them together there would be a gap on the ID side

[@LearnEverythingAboutDesign]

Yes. As long as the number of teeth, hirth angle and the ID/OD values match they should fit. Keep in mind if you are 3d printing these the height when you screw two together may increase based on the type of printing you are doing.

Thank you so much for making this video! It’s exactly what I was looking for!

Hey, exactly what i was looking for ! well made video. I chose to simply download from the updated link you gave since i dont really know my way in design and fusion but everytime i change the values only 1 teeth remains and i cant seem to fix it.

[@LearnEverythingAboutDesign]

which values are you trying to change?

[@Edouard03]

@@LearnEverythingAboutDesign ID OD and number of teeth and teeth angle

[@LearnEverythingAboutDesign]

@@Edouard03 I just tried some variations with this file a360.co/3i9ne8w and it worked. I changed the OD to 150. the ID to 100, the HirthAngle to 65 and the number of teeth to 60. all updated ok. if you let me know the numbes you are trying i can see if they work for me.

[@Edouard03]

@@LearnEverythingAboutDesign I messed around a bit and it seems to be the ID causing issues, i need the ID to be 6.1 mm but the lowest i could make it work is 14mm, anything smaller breaks it

[@LearnEverythingAboutDesign]

@@Edouard03 If you expand the sketches, sketch 12 defined the hole in the middle which is currently set to 24mm. The design wasn't set up to be able to go that low so you would need to dive in a bit deeper. Sketch9 defines an offset value for the tooth cut and it used an arbitrary offset number of 3mm to make sure it extended far enough. The problem when you make the ID so small is that it now crosses the axis of revolution which it really doesn't like. What might be easier if you just need a 1 off is to get the ID and OD to a larger multiple of what you need, and scale the whole thing down. Say you make it 18.3mm ID then scale it down to 1/3 the size.

Great video explanation is easy to follow, would you consider doing a tutorial on a Planar Index Joint (might be the wrong term) but there are a couple of videos of them being shown

[@LearnEverythingAboutDesign]

Great suggestion! Do you mind linking me to a video on the topic?

[@ChrisOndrovic]

@@LearnEverythingAboutDesign I tried to reply a couple of times but for whatever reason they didn't post kzbin.infokPQaCk-VqMw

[@LearnEverythingAboutDesign]

@@ChrisOndrovic That is odd. YT doesn't like links sometimes, even to their own site :) you can always email me [e-mail] too. I see that is a cool joint! I won't how long that ball end bit would last.

[@magnehoiberg]

toothangle formula gives me an error all the time, can you post a copy off yours, so i can check what i am doing wrong?

[@LearnEverythingAboutDesign]

The download file in the description should have it no? There was an updated to Fusion after this video was made where more parameter functionality was included so ill have to give a shot on my end as well and get back to you if I have problems.j

Hirth angle, Hirth angle, oh won't you be miiiine?

ahahah. That instantly takes me to back to the future. I am your density, uh destiny

Very nice explanation.
