how on gods green earth do you measure a curvic coupling pitch??
:?
Dunno, but it sounds x-rated to me...
I know NOTHING about Curvic Coupling. So out of curiosity, I did a little web searching. It sounds like the people who would know are CMM experts. The various results I found talked about measuring it with a CMM. Don't know if that's of any help.
Gleason's website says:
http://www.gleason.com/b_services_sgs.html
Gleason designed, developed and patented the Curvic® Coupling, along with the machines that produce the unique Curvic Coupling tooth form. We have unique expertise and comprehensive resources allowing us to provide Master, and Curvic Couplings – everything from the initial special design to manufacture including precision grinding, inspection and certification. Gleason can provide the same expertise for those customers seeking to upgrade an existing Gleason-Hurth serration coupling design to the higher precision and accuracy of Gleason Curvic Couplings.
Metrology
Gleason can validate your gears using the latest metrology equipment and inspection techniques. We can inspect and certify all types of gears from cylindrical, bevel and hypoid, worms and worm gears, special tooth forms such as Curvic Coupling, etc. We have the capability to perform elemental inspection checks, single flank and double flank composite checks and structure-borne noise analysis.
For further details, contact your Regional Sales Manager or call (585) 473-1000 ([email protected]). You could contact them and see if they would be willing to share their procedure. Alternatively, you could have them calibrate it and reverse-engineer your own procedure from the cert; make sure to get the one with data. HTH
Thanks
Most people use a blue technique when testing them. No way will this part ever be sent to anyone outside of this base for checking as it's too important.
There has got to be a way to check the pitch with an Optical comparator.
I will ask Gleason if they will share.
A "blue technique"? Pray tell.
Glad to help; hope it did.
