EVALUATION OF THE EFFECTIVENESS OF THE COMPANY REPAIR OF MACHINERY AND EQUIPMENT BASED ON STATISTICAL ANALYSIS OF WEAR

Abstract

Due to the economic crisis in all sectors of the economy, as well as insufficient funding, there is now a significant decline in the production of agricultural machinery. Therefore, agricultural enterprises are unable to purchase new equipment. In this regard there is a need of competent planning of use of the available equipment so that it could be used most effectively, with the minimum expenses for repair and maintenance. The economic efficiency of agricultural enterprises plays an important role in the reliability of equipment, so its forecasting by various means allows to reduce the total cost. Proper operation and timely repair of machinery and equipment can improve efficiency, thereby reducing downtime. Currently, there is a rather acute situation with the problem of reliability of machines. This is primarily due to the increasing complexity of the design of modern machines and mechanisms, their large number, intensification of work processes, severe operating conditions. The efficiency of solving the problem of replacement or repair of parts, and therefore the question of the economic efficiency of the repair company, is directly dependent on the degree of scientific and methodological support of relevant activities, one of which is the process of assessing the wear and tear of parts. Purpose: to investigate efficiency of work of the enterprise for repair of cars and the equipment on the basis of the statistical analysis of wear of a neck under a ball-bearing of 208 shaft of a primary gearbox MTZ-82 to establish that in this case more effectively-repair or replacement of the considered detail. Methodology in article: statistical analysis methods. Results: Received the most informative parameters indicating the wear of the neck under the bearing 208 of the primary shaft of the gearbox MTZ-82. On the basis of the conducted analysis it is established that, from the economic point of view, timely maintenance and repair of the considered part is more effective than its replacement with a new one. Practical implications: the results can be used to assess the economic efficiency of the enterprise for repair of machinery and equipment.
