“…The simulation of gearbox components was also used to identify the causes of gear failures including TE, macro and micro geometrical errors, material homogeneity errors and other possible causes of gear noise to optimize and improve gearbox life [15]. Zhang et al incorporated the unavoidable meshing errors in their study on the gear tooth modification (GTM) and provide an improved shape for the gear dynamic performance [16]. The effects of constant and fluctuating loads and the shaft speed on the helical gear dynamic response were used to establish a direct relation between shaft speed and its alignment [17].…”

Failure in gears, transmission shafts and drivetrains is very critical in machineries such as aircrafts and helicopters. Real time condition monitoring of these components, using predictive maintenance techniques is hence a proactive task. For effective power transmission and maximum service life, gears are required to remain in prefect alignment but this task is just beyond the bounds of possibility. These components are flexible, thus even if perfect alignment is achieved, random dynamic forces can cause shafts to bend causing gear misalignments. This paper investigates the change in energy levels and statistical parameters including Kurtosis and Skewness of gear mesh vibration and airborne sound signals when subjected to lateral and angular shaft misalignments. Novel regression models are proposed after validation that can be used to predict the degree and type of shaft misalignment, provided the relative change in signal RMS from an aligned condition to any misaligned condition is known.
