How to Combine Stress Concentrations for Multiple Keyways on a Shaft?

Click For Summary
SUMMARY

The discussion focuses on combining stress concentrations for multiple keyways on a shaft, specifically addressing the adaptation of Soderberg shaft design calculations for feather type keyseats and parallel keyways. A recommendation is made to consult "Machinery's Handbook" for comprehensive information on stress concentrations. The need for accurate calculations in the presence of multiple keyways is emphasized to ensure structural integrity and performance.

PREREQUISITES
  • Understanding of Soderberg shaft design calculations
  • Knowledge of stress concentration factors for keyways
  • Familiarity with feather type keyseats
  • Access to "Machinery's Handbook" for reference
NEXT STEPS
  • Research stress concentration factors for feather type keyseats
  • Learn methods for combining stress concentrations in mechanical design
  • Study the Soderberg design criteria in detail
  • Explore additional resources on shaft design and keyway configurations
USEFUL FOR

Mechanical engineers, design engineers, and students involved in shaft design and analysis, particularly those working with keyways and stress concentration calculations.

Hello

I have done a Soderberg shaft design calculation, taking into account the stress concentration for a keyway. However, I've just noticed that I might need to adapt this for a feather type keyseat, or 2 (parallel, 180deg apart) keyways in the same cross section.

I'm sure I read somewhere about how to combine the stress concentrations in this situation, but I can't find where I read it. Does anyone know off the top of their heads?

Cheers

Try Machinery's Handbook. I don't have it in front of me, but it has a lot of information on stress concentrations.
