Analysis of Pulley/Sheave Pins Question
Analysis of Pulley/Sheave Pins Question
(OP)
Can the pins in pulleys/sheaves be modeled as fixed-fixed?...if so, what standards must be followed for hole sizing? Is their a standard to follow?
I have always modeled them as pinned-pinned(symply supported), but I was asked this question and not sure about it.
I also found this info on the engineersedge website, but not sure if it would apply:

I am also doing shear stress calcs, I just thought I needed to include bending calcs as well.
So based on what your saying the worst case for pins is shear stress.....Right?

I have referenced "Schaum's Machine Design" for clevis design and he includes bending caculation for a clevis pin.
Here is the link to his book:

This should of been the question I asked in the first place.
I am still debating what mode of stress defines my system.
I am leaning towards doing simply supported and design for shear stress and make sure that the bending stress does not go over yield strength.
