        abstract = {This study experimentally validates frequency domain analysis for fault diagnosis in a single-stage bevel gearbox. Vibration signals were acquired from a test rig under varying speeds and loads for nine conditions: healthy, isolated gear faults (wear, pitting, corrosion, fracture), isolated bearing faults (wear, pitting), and combined gear-bearing faults. The results demonstrate that characteristic frequencies provide definitive fault signatures. Gear faults, particularly fracture, elevated vibration amplitude at the gear mesh frequency and its harmonics. Bearing defects were identified by increased amplitude at their specific pass frequencies. Combined faults produced a superposition of these spectral features, with the coalesced gear fracture and bearing wear condition generating the most severe vibrational response. The method conclusively discriminates between fault types, providing a critical tool for precise condition monitoring of bevel gearboxes.},
