Shaft Torque vs Stress Explained

該当する場合

Use this guide when you need to explain how a shaft can carry torque yet still fail on stress or stiffness long before a detailed machine-element study is complete.

使うツール

Torsional shear stress and angle of twist for solid or hollow circular shafts.

手順

  1. 1Start from the applied torque and the shaft geometry you are screening.
  2. 2Compute the shaft polar moment and peak torsional shear stress.
  3. 3Estimate angle of twist if shaft length and shear modulus matter for stiffness.
  4. 4Compare solid and hollow concepts on both stress and torsional stiffness logic.
  5. 5Escalate to fatigue, keyway, and combined-loading checks for final shaft design.

例

  • Checking whether a shaft concept is stress-driven or twist-driven.
  • Comparing hollow and solid shafts for the same torque requirement.

避けること

  • Confusing torque capacity with allowable stress directly.
  • Ignoring stress concentrations from keyways or shoulders.
  • Skipping twist checks when alignment or backlash matters.

よくある質問

Does a lower stress always mean a better shaft?

Not necessarily. Stiffness, fatigue, geometry, and manufacturability can still govern.

Can I use this for keyways and splines?

Not directly. This guide assumes a simple circular shaft without local concentration features.
