Abstract

The purpose of this research is to study wear mechanism and propagation of gear rotating components. The gear test rigs are design and develop for on-line vibration health monitoring system. This research exhibit the effects of wear propagation over time toward vibration level in a system using vibration analysis, in order to detect defects of rotating gears. The vibration signals of helical gear were collected and then analyzed using Fast Fourier Transform (FFT) technique. During the experiment, the sample of gear lubricant was collected in order to investigate the quality of wear characterization of the rotating gear. The lubricant is analyzing using wear debris analysis. Besides, the particle sizes of debris are also measured. From the study, it was found that the maximum amplitude of GMF value is 1.124 mm/s when 30 kg of load is applied to the rotating gear. The value is influenced by the occurrence of the debris and contaminant in the gear lubricant. The ferrous particle that presented show the certain wear mechanism happen on helical gear.
