Abstract The properties of the time synchronous averaging method, aimed at identifying informative components in the process of gear diagnostics, are considered, which makes it possible to improve the signal-to-noise ratio of the vibration signal and determine which element of a transmission unit with several rotating shafts is the source of increased vibration. This method of processing the vibroacoustic signal also makes it possible to assess the condition of individual elements of gear systems. The relevance of using the time synchronous averaging method in vibration diagnostics of transmission systems of mobile machines is shown, due to the possibility of averaging signals both for stationary processes and at varying rotational speeds. The algorithm of the time synchronous averaging method used in the vibration monitoring system of gear drives developed by the Joint Institute of Mechanical Engineering of the NAS of Belarus is described. As part of the further development of the comprehensive methodology developed by the authors for detecting, localizing and identifying incipient gear damage, the use of a number of dimensionless discriminants in vibration diagnostics of a planetary gearbox is considered. As an example of their application, the analysis of experimental data obtained as a result of vibration monitoring of the technical condition of the motor-wheel gearbox of a mining dump truck is given.
