Press Fit (thin wall SS tube) 1

[notTiger]

Hi

Need some help in designing a press - interference fit

We have a 6-4 Titanium collar (OD 22.2mm ID TO BE DETERMINED) which we currently connect by loctite to a:

14.1mm OD,
13.1mm ID
304 Stainless tube (not annealed)
6mm insertion of tube into the titanium

Despite our best efforts the loctite works 95% of the time only!

I wonder if someone could help us design the ID of aperture in the titanium part- for a press fit

The press force available would be that normally availble in workshops only

We out source production and want to make some best guess prototypes, and as you know titanium is expensive +

Cheers Simon

Loctite won't work reliably if there is a press fit. Read the application notes for whichever Loctite product you are using.

Seee the FAQ section for a calculator for press fits.
