The purpose of condition monitoring, and fault diagnostics are to detect faults occurring in machinery, in order to reduce operational and maintenance costs, and provide a significant improvement in plant economy. The condition of a model drive-line was investigated. This model drive-line consists of various interconnected rotating parts, including a gearbox, two bearing blocks, and an electric motor, all connected via flexible coupling and loaded by a disc brake. The drive-line was run in its normal condition, and then single and multiple faults were intentionally introduced to the gearbox, and bearing block. The faults investigated on the drive-line were typical bearing and gear faults, which may develop during normal and continuous operation of this kind of machinery. This paper presents the investigation carried out in order to study both bearing and gear faults introduced together to the drive-line. It is shown that, by using multilayer artificial neural networks on the condition monitoring data, single and multiple faults were successfully classified. The real time domain signals obtained from the drive-line were pre-processed by Wavelet transforms for the network to perform fault classification.
