Off-centered agitator shaft design

Off-centered agitator shaft design

Off-centered agitator shaft design

(OP)
We need to determine the size of a off-centered agitator shaft with no bottom steady bearing. We are concerned about the fatigue issue because of an additional bending force due to the off-center. Can anyone help on how we can estimate that force without CFD or how much bigger the shaft probably needs to be compared to center-mounted one if it off set by 20% of the tank ID. Thank you,

I can't help you with the calcs, but if it were me I'd call Chemineer and/or Lightnin for a quote, or do ya'll buy pieces parts and make your own?

Good luck,
Latexman

We are going to make it our own. I think I need to apply a service factor for the off-center but I could find how much it need to be. Thank you

Sorry, I mean I could not find the service factor for off-centered shaft design.
