Clevis Pin Size
Clevis Pin Size
(OP)
This is not a topic I have any experience in so I'm hoping someone could give me a book reference as to the theory behind the design of these or something along those lines.
I need to determine whether or not a pin of 5.00" diameter can be used in a hole designed for a 5.25" diameter pin.
I imagine all I would need to check is for contact surface deformation, pin bending and shearing stesses...correct?
Would the extra clearance caused any problems?
Thanks...

RE: Clevis Pin Size
There are many reasons why what your proposing is plain dangerous.
RE: Clevis Pin Size
Is there something else that should be checked for in relation to the clearance of the proposed smaller pin? Or, is it just a matter of the previously mentioned items?
RE: Clevis Pin Size
Po=0.591*Sqrt[{(P1*E1*E2)/(E1+E2)}*(1/R1-1/R2)]
Note stresses can be very high due to the small contact area. To reduce the stress reduve the clearance between the two bodies.

I would say that, at first glance, I would be wary to use a pin .25" less in Ø, but it all depends on the variables involved.
Good Luck
