Curvic coupling 1

[borjame]

Hello all, I'm looking for info on curvic couplings, their shape, standard sizes, how they're cut, load calcs, etc. I've contacted some machining suppliers, would like to get a head start. Any and all info would be appreciated.

Contact Gleason. They have booklets which explain how to design them (or they used to, cause I've got em). Gleason are the only people who make the machines which are used to make them, as far as I am aware. However, you would probably be better off with a Hirth coupling these days - and they are a lot simpler to design.

You might want to checkout these people. We did use them at one time. I'll try to check and see who we use now.

Hi CurvicGuy,

Probably you will prefer Curvic, but I have been told that hirth is even more accurate that curvic and much more cheaper than curvic. I think that in Europe most of machine-tool manufacturers use hirth but in Japan they use Curvic. What is the reason?

Do you know, apart from machine tool, where and who can use hirth couplings?

In hirth, I know Tedisa. I have been told they are very good.

. Do you another manufacturer for hirth? and for curvic?

Thank you

Here is a site posted by aamoroso for a company that makes both Hirth and Curvic couplings.

I do not have much experience with Hirth couplings, but thanks to unclesyd I will be able to increase my knowledge.
Thank you!
