Health monitoring of rotating machinery, particularly gearboxes, is crucial for ensuring operational efficiency and preventing unexpected failures. Gearboxes are among the most critical components in rotating machinery, with gears playing an essential role in transmitting torque and maintaining appropriate speeds. Due to the importance of fault diagnosis and predicting the remaining useful life (RUL) of gearboxes, numerous studies have recently been conducted in this area. One widely used method for predicting the RUL of equipment is accelerated life testing. To achieve this, a test bench was designed using CATIA software to estimate the RUL of spur gears, which are key components of gearboxes. Subsequently, dynamic and vibrational analyses were conducted using ADAMS software. These analyses included investigating the impact of vibration interference caused by the operation of the crank and spring mechanism—a load applicator on the gear teeth. Simulation results were compared with experimental data, confirming the model's accuracy. Additionally, vibrations from the crank and spring mechanism did not affect data related to gear faults. Experimental data collected from the system showed that the engagement frequency range of the gear increased from 44.5 dB to 66.87 dB, and the presence of sidebands around this frequency indicated wear-related faults. The findings of this research suggest that the collected data can be effectively used to estimate the remaining useful life of gearboxes.
