“…Based on the results of studies of maintenance regimes for complex equipment [12][13][14], the need to consider the most important of them -diagnostics -was determined. Modern diagnostic tools that determine the technical condition of an energy-saturated equipment during operation, including non-contact diagnostics, use a large number of control indicators (fuel consumption, temperature conditions, crankshaft rotation speed, pressure pulsation, etc.)…”

Agricultural production in Russia solves the most important national problems - food security and import substitution. The conducted research substantiates the need to improve the engineering service of the agro-industrial complex through the introduction of modern innovative technologies. The article outlines the basic principles and technical means that determine the system of maintenance and repair of machines in the agro-industrial complex, as well as the mechanism of relations between manufacturers and consumers of technical means. Current issues of individual subsystems of the repair and maintenance base in the engineering service of the agro-industrial complex and the main groups of repair and maintenance impacts on domestic agricultural machinery were considered, and a relationship was established for foreign-made machines with all elements of maintenance, repair, modernization and disposal. Information is presented on depreciation rates and recommended distributions of the volume of repair and maintenance work by facility.

“…Therefore, diagnostics by the temperature measured on the outer surface of the bearing assembly has no practical application [10][11][12][13][14][15]. Modern technologies and technical means of temperature measurement make it possible to perform thermal diagnostics automatically, without manual labour, but only when measuring the temperature of the outer surface of the bearing assembly [16][17][18][19].…”

The purpose of this work is to prove the effectiveness of a practical study of the temperature regime for diagnosing bearing assemblies of mechanical transmissions. Using the example of a two-row roller bearing of the rear support of the intermediate shaft of the vehicle transmission, the temperature in the friction zone under different transmission operating modes on a KAMAZ-5320 was calculated. Finite element analysis of temperature fields made it possible to determine the relationship between the temperature on the outer surface of the bearing assembly and the temperature in the friction zone through the coefficient k=0.327. The zone for temperature measurement -the bearing cover is determined and the maximum temperature of its heating is set. Thermal imaging observations confirmed the effectiveness of the developed method of technical diagnostics of bearings.

“…It is often when hydraulic pumps are resource-limiting components of the units in whose design they are included, and the condition of the hydraulic pump determines the performance and efficiency of the entire unit. The importance of diagnosing hydraulic units is evidenced, for example, by the fact that according to National State Standard 20793-2009, when the internal-combustion engine (IС engine) reaches 1000 engine hours, motor maintenance (MM-3) is carried out, which are combined with resource diagnostics (RD) to obtain initial information on predicting the residual resource including the hydraulic pump [1,2].…”

It is well known that often hydraulic pumps are resource-limiting components of the units in whose design they are included, and the condition of the hydraulic pump determines the performance and efficiency of the entire unit. The purpose of the work was to develop a prototype of a diagnostic tool that provides monitoring of the technical condition of hydraulic pumps during operation. An analysis of the tools produced by the Federal Scientific Agro-Engineering Center VIM for diagnosing the technical condition of hydraulic pumps of agricultural machinery was carried out. The material of research was a prototype of a tool for diagnosing the technical condition of hydraulic units, which was based on the method of amplitude-phase characteristics for rapid assessment of the technical condition of pumps during operation. On the base of our research we came to conclusions that for further development of the technology and subsequent implementation of the presented prototype in the process of diagnosing hydraulic pumps by pulsation coefficient it is necessary to increase the controllability of hydraulic systems of agricultural machinery by installing diagnostic points for connecting pressure sensors. Also together with manufacturers of hydraulic units, develop criteria for nominal, permissible, limit states, characterized by both the supply coefficient KQ and the pulsation coefficient ɛ.
