Shaft calculation

Shaft calculation

Shaft calculation

(OP)
I calculated shear stress of the shaft based on the torque and found it is within the torsional yield of the material. Can I say design is safe. Or should I need to find angle of twist?

RE: Shaft calculation

might want to consider bending moment...

RE: Shaft calculation

Add fatigue analysis in case the system has cyclic stresses.

RE: Shaft calculation

For shaft calculations in addition to the above you need to evaluate bending stress along with torsional stress, and decide on an appropriate safety factor. So, no I would not consider it safe.

RE: Shaft calculation

How is the torque getting into and out of the shaft?
Does the torque vary over time?
How long would you like it to last?

RE: Shaft calculation

Google shaft design
