A shaft transmits torque and rotates with the connected components, while an axle primarily supports rotating elements without transmitting torque. Shafts are designed for torsional loads, while axles handle bending loads.
Shaft diameter is calculated using torsion formula: d = (16T/πτ)^(1/3), where T is torque and τ is allowable shear stress. Additional factors include fatigue loading, bending moments, and safety factors per ASME B106.1M.
Common causes include fatigue from cyclic loading, torsional overload, corrosion fatigue, improper heat treatment, stress concentrations at keyways or splines, and resonance at critical speeds.
