hirth coupling
hirth coupling
(OP)
Hi
I'm looking for any info on the design of hirth teeth, primarily why the need for such a high surface finish and tolerance. I'm guessing the high tolerance is an alignment thing as probably these coupling are used for high speed applications.
Anything would be useful.
I've already viewed this thread:

I would be quite interested in a copy of arnoldh design notes, if they are still around.
thanks
allan

RE: hirth coupling
1) Hirth couplings are used for angular positioning. Machine tools use them on tool turrets. If you want to position the tool accurately then your teeth need to be accurate.
2) Load sharing between the teeth only works if the teeth are accurately spaced and sized.

Here is a fair bit of info from about four years ago.

Oops, didn't notice that, sorry!!
RE: hirth coupling
Would you have any references, best practice guidelines for tolerances?
thanks
