Circlip resistance calculation

[Faroukpin]

Hello
I'm designing a stainless steel hinge with bronze bushings, and I've chosen to secure the pin using two E-type circlips.
I would like to know if the circlips can withstand the loads (which I don't know how to calculate).

I would like to create a calculation note to verify whether my design solution is suitable.

Could you help me, please?

Here are the conditions.


Here are the allowable forces specified by the circlip manufacturer.

I can't understand how your hinge is supposed to work.

What are the orange parts?

Where is the pin?

The axial load on a typical door hinge pin is very close to zero. I have a door where the hinge pin defies gravity and moves up. It takes about 10 years to get to where it looks like a problem.

Why do you suppose there is any meaningful load on the circlips?

EDIT: And why are you not just buying hinges?

100kg is pretty heavy for a door. I agree determining the axial load on these pins is very nebulous, but
1) why not an off-the-shelf hinge ?
2) are a hinge producer make you a custom one (if you feel your needs are special) ?
3) just drop a bolt in, as a pin (what would cause the pin to migrate upwards significantly ?)
4) is there some security issue (like you don't want people to tamper with it) ?

Ok, so the orange parts are the bronze bushings.

You understand that only one of them is in the load path, right?

I still don't see a pin.

Hello and thank you for your responses
I'm trying to explain my need.
What I'm interested in is whether there are forces on the circlips that could make them pop off.
The leaves, the pin, and the self-lubricating bushings will not be on the study.

Here is my reasoning:
The moment created by the weight of the door will generate forces that I want to calculate.

There is a gravitational force, and when I transfer that force into the hinge (shown in red),
and if I break down the moment transferred into the hinge, I think there will be two components, F1 and F2 (in green).

Is my reasoning correct?
And how can I calculate this force?

Thank you
