Interference fit of a ring in a groove

[Calculost]

Imagine a thick cylinder with a retaining ring groove cut in the ID. I'm replacing the retaining ring with a split ring pressed into the groove.

The split ring I'll have made along with the tool to install it.

What I would like to determine is the amount of interference and the force required to press the ring into the groove.

I can do pin and hole press fit calcs all day and twice on Sunday. Now I'm not looking for a formula...unless it's in Mathcad, then by all means ... I'm just looking for a starting point.. an idea where I should look.


Cheers!
Ken

The best place to start is to measure the exact dimensions of the groove, as well as the exact dimensions of the split ring. You can then use a tool like FEA or a mechanical calculator to determine the amount of interference and force required to press the ring into the groove. Additionally, if you have access to a press, you can use it to test different combinations of rings and grooves to determine the optimal fit.
