The article shows the relevance of improving the maintenance system of belt conveyors. The work features of mining gearboxes and the complexity of diagnosing the processes of wear in their elements are considered. On the one hand, the variable character of the load and changeable speed of the conveyor in accordance with the needs of the technological process from another part interferes in the operation of diagnostic systems. The results of the distribution of the overall level of vibration on the same type of gearboxes show different rates of degradation of their nodes. A solution to the problem of assessing the technical condition of the gearbox elements using the “floating” reference spectral masks is proposed. Spectral masks are created for several speeds of the belt movement. The amplitude levels of the velocity vibration characterize defects. They are changing depending on the frequency. They so to say “float”. The spectral masks of the “warning” level and the results of assessing the state of the gearbox with their use are shown.
