JQCZAG. RESOURCE-SAVING SYSTEM OF MAINTENANCE AND REPAIR OF MACHINES

Abstract

The article presents the results of research on the maintenance and repair of agricultural machinery, as well as strategies for maintaining it in working condition. The system of technical support and repair of machinery in agriculture is maximally focused on the strategy of performing repair and maintenance actions with periodic or continuous monitoring. (Research purpose) The research purpose is studying the possibility of using a new resource-saving tolerance system for machine parts in the existing maintenance and repair system. (Materials and methods) The assessment of the technical condition of individual units and (or) tractor systems with the use of built-in and portable devices and the determination of their residual life make it possible to predict a repair time and prepare the workplace, spare parts, replacement units, aggregates in a timely manner. The technical and economic condition of the agro-industrial complex is mainly determined by two factors: providing agricultural producers with a regulatory need for agricultural machinery, its reliable maintenance and repair using modern technologies, including the use of a system for assessing the operational properties of the main indicators of machine reliability. (Results and discussion) The article presents the issues of import substitution of repair and technological equipment during the repair and maintenance of agricultural machinery. Authors have developed promising directions for the strategy for the maintenance and repair of agricultural machinery. The repair technologies and reliability indicators of agricultural machines were described. (Conclusions) As a result of the conducted research, the article presents the methods of improving the system of technical service of agricultural machinery, recommendations for their improvement and modernization. We have developed a maintenance and repair strategy based on minimizing the residual life of machine parts.
