O-ring groove design for non-circular groove
Hi,
I am designing a static seal with an o-ring.
The particularity is that the groove is non-circular. It has an oval-like shape (see picture in link below).
I am wondering how to calculate groove dimensions.
The medium is compressed air of 10 bar.
Pressure is on the inside, so the o-ring is pressed to the outermost groove wall.
I was thinking to calculate the groove the standard way as if the o-ring was placed in a circular groove, using some online calculator or the Parker Handbook.
Then, I would calculate my oval groove so that the outside wall ('outside circumference') of the oval groove has the same length as the outside wall of the circular groove.
Groove width and depth according to the standard calculations.
Would this be an acceptable calculation method?
Kind regards
Ray

O-ring groove design guides offer default dimensional guidance on the most basic o-ring groove design applications. The best o-rings are useless without the right groove design which becomes increasingly important the more demanding the application environment. Review the general o-ring groove design considerations before moving onto the specific o-ring gland design type.
