Theoretical substantiation of machine-tractor fleet technical maintenance system on the example of Omsk region agricultural enterprises

Abstract

Machine and tractor fleet increasing reliability problem solution in the production conditions of agricultural enterprises is an important and urgent task of agro-industrial complex engineering service. It can be solved by the machines downtime reducing for maintenance (maintenance service) with intensive method use of performing operations in the unstrained field work period, as well as maintenance service transfer to specialized technical service enterprises partly. One of the contradictions inherent in the of machine maintenance planned system is work timing coincidence of, that is, the more time, the more maintenance operations must be performed. As a result, during intense field work periods, the machine operator, in order to ensure high operating time, to the prevention detriment is forced to eliminate only failures consequences, which leads to their increase, machines productivity is reduced, and operation costs are increasing. In modern conditions, when the machine operator has more than one machine, he is not physically able to perform maintenance and repair operations on time. Therefore, it is advisable to transfer to specialized enterprises part of the work on complex maintenance and repair. The article proposes and justifies technical service formation structure at agro-industrial complex enterprises.
