The research is aimed at revealing the problems of modeling technical diagnostics of mechanisms and machines. To assess the technical condition of machines and the formation of diagnostic features, a method based on the application of the mathematical theory of pattern recognition is proposed. It is shown that technical diagnostics of machines and mechanisms can be interpreted as the recognition of classes of technical condition of the object by the set of its technical characteristics. At the same time, it is established to what class the current recognized state belongs. The conducted studies are covered against the background of the assessment of gear defects. Such studies have shown that in the early stages of defect development there is a process when synchronous components do not grow, and all the extra power from the defect is concentrated in asynchronous harmonics.
