Shrink fit of a stainless ring onto a shaft 7

[Tiogar]

Hello all,

I'm working on a new procedure at work (machinist/welding), and I've gotten conflicting answers on the formulas I need. I just started a ME program, but we haven't covered this yet.

I'm trying to shrink fit a stainless steel ring onto a stainless shaft, rather than us welding it up and machining it down.

The OD of the ring is 120mm, with an ID of 114mm and a width of 7mm. The shaft is 114 mm, with no ID. I'm trying to do the largest shrink fit I can, without causing materiel failure in the ring.

I can do the calcs for how strong the fit is, but I'm having trouble finding the calc for the max interference fit I can have without causing the ring to fail. It's a non-load bearing part. It's there to act as a corrosion barrier.

I've seen online calculators, but I'd rather know the math and theory behind it, if anyone can point me in the right direction.

Thanks!
Jeremy

I would gladly provide a copy, but, sorry to say, I don’t use Excel. I produced the template using Mathcad.
