Power Transmission Shaft
Design a power shaft by torsional rigidity (twist ≤0.25°/m) and shear strength; take the larger diameter.
Inputs
Formula
T=9550P/n; d_rig=⁴√(32T/(πGθ)); d_str=∛(16T/(π[τ]))
How to use
- Fill in Power P, Speed n, Shear mod. G, Allow. shear [τ], Allow. twist in the Inputs section (watch the unit on each field).
- Click Calculate; the tool evaluates the formula shown above.
- Read Torque T, By rigidity, By strength, Recommended in the results area.
Formula notesShaft power P = T·ω = T·2πn/60 (kW); torque T = 9550·P/n (P:kW, n:r/min).
