“…The Time Synchronized Analysis (TSA) widely used, for instance in [6], became the most usable technique for gear vibration development allowing to suppress the external vibration sources. The authors also used the above techniques in their studies for different gear types including planetary ones [7]. In [8] the study of transfer functions was discussed, including the dependence on the type of the excitation source, as well as experimental techniques of the transfer function identification were considered.…”

The paper presents the approach allowing quantitative evaluation of gear damages, which makes it possible to estimate the technical condition of the machine where the gear applied. The models of dynamic loads in a gear and vibrations are described, and specialties of gear transfer function are discussed. The diagnostic parameter is presented that allows quantitative evaluating the gear damage using tri-axial vibrations. The proposed algorithm of diagnostic parameter computation was experimentally tested, and the results of its validation are presented. There are conclusions about capability of the proposed algorithm for quantitative estimation of gear technical condition.
