Goodevening,
I have to design the slow shaft of a motorgear that is subjected to bending and torsion.
I was given this conceptual design of the shaft (the portion with a larger diameter is the gear):
There is a keyseat that cuts into the shoulder of the pinion, making it difficult for me to determine the Kt coefficient, since a case where the shoulder effect and the keyseat effect are both present is not documented on Peterson's handbook.
I thought I could use a FEA but I would always need the Kt coefficient to dimension the model, so I find myself in a dead end.
Moreover I don't understand the use of the fillet in the red circle.
Any advice is welcome,
thanks
