FIELD: engine building.
SUBSTANCE: invention relates to methods for diagnosis of technical condition of engine reduction gearboxes and can be used in assessment of technical condition of reduction gearboxes. Method consists in that signals are divided into positive and negative components, each component is analyzed, obtained results are compared by amplitude, note here that maxima of positive and negative areas are pre-selected to analyze them, to compare obtained data and to determine technical condition of gear transmission based on comparison results.
EFFECT: technical result is broader functional capabilities, high sensitivity of measurements.
