And now you do not manufacture hirth couplings for turbines or you just changed your job?
Yes, I really had already heard that Siemens, for example, uses hirth couplings in it turbines, but never sawed anywhere else than in tool machines.
i think that aeronautics also uses hirth (or maybe...
Hi Dynoguy68,
What is the application you would use the coupling? Anyhow, I think that hirth couplings is more accurate and much cheaper, as teeth in both pieces are the same and in curvic the profile of the grinding wheel is different in each of the pieces, fact that increases the cost of...
I also think that in www.tedisa-hirth.com have some formulas to calculate and design the hirth teeth. They also have some standard coulpings, so I believe they have already been calulated to support a high torque force.
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...
You should visit this page: www.tedisa-hirth.com
The webpage is a bit old but they will probably help you. I know some people who use their hirth couplings and they just told me that the accuracy and the quality was fantastic. Before he used curvic coupling but he has definetely changed to hirth...
