Name for this part/mechanism? 6

[NextDaVinci]

I am referring to the gear-like circular faces that interlock when forced together and allow rotation when unlocked on these arms. I want to design one, but I can't seem to find out what its called.

Any advice as to how to make these out of metal in a basic machine shop is also welcome.

Thanks!

Hirth coupling?

We make Hirth couplings all the time in our prototype shop. A rotary indexer and the desired angle of vee cutter is all that's required. (and a milling machine, of course)

It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.

Thank you, you guys are awesome.

In the future, are there any tips or resources for how I might go about figuring that out without asking the forum?

Cheers.

I assumed I didn't know what it was and simply used google for "toothed rotational joint" and was able to find reference to a hirth joint in the first page that came up. But didn't find it so easily with Bing.. take that microsoft.. Google > Bing now matter what your commercials say

They can put bing where the sun don't shine.

That's where it came from.


Thanks for identifying the Hirth joint - my little bit of learning for today.

depending on the accuracy and increment a simpler jaw or dog coupling might suffice
