TI  - GEARBOX FAULT CLASSIFICATION BY USING FREQUENCY BASED FEATURE EXTRACTION
AB  - Gearboxes are the fundamental elements of rotational systems to provide speed adjustment ratios from a rotating power sourceto another. In industrial applications, the existence of any kind of faults in rotational systems may be hazardous unless the earlydetection and maintenance procedures are applied. Incipient types of faults such as a few chipped or worn teeth at the gearboxmechanism may deteriorate and cause the maladjustment of the rotation and even the mechanism may stop to rotate which maycause loss of the production. Preventive maintenance strategies such as monitoring of the vibration signals and comparison ofthe frequency domain irregularities with normal operation case with healthy gearbox elements is essential to ensure safe andaccurate rotational speed transmission in industrial systems. In this work, frequency domain characteristics of three differentpinion conditions; healthy, a chipped tooth, and three consequent worn teeth are analyzed, and frequency domain features areproposed for classification of the pinion state. Proposed features obtained from the statistical properties of the coefficients ofthird level Wavelet packet decomposition. After feature extraction process, classification of the gear condition is made withdifferent Support Vector Machine based classifiers and significant classification success observed with the proposed technique.
