dc.description.abstractThis paper investigates gear diagnostics using laboratory measurements on a specially-designed planetary gearbox test-rig. Planetary gearboxes present a unique challenge to the condition monitoring community. They are complex units, comprising many rotating components, and any vibration signal arising from a faulty gear or bearing, as measured on the outer casing, is likely to contain a substantial amount of extraneous information. While a number of signal processing techniques have been developed in attempts to overcome these difficulties, in this paper we investigate the potential of using an internally-mounted accelerometer to give improved diagnostic performance in the case of seeded planet gear faults. The vibration is also measured on the outside of the gearbox casing and the diagnostic potential of the two measurements is compared. It is found that in most cases the internal measurements actually give inferior diagnostic performance, although some problems with the internal signals preclude a complete comparison. Along with the measurement points, two diagnostic procedures are compared, both based on the kurtosis of the residual signal obtained after removing regular gear meshing components. The first is based on the well-known FM4 parameter, which uses time synchronous averaging to establish the regular meshing pattern. The second focuses on kurtosis enhancement using autoregressive linear prediction filtering followed by spectral kurtosis. The latter method was found to greatly increase the detection capability, with very high kurtosis values obtained in most fault cases.
