TECHNOLOGICAL METHODS OF INCREASING WEAR RESISTANCE AND DURABILITY OF DETAILS
Olena Trukhanska – Ph.D, Associate Professor, the Department of Agroengineering and Technical Services of the Vinnytsia National Agrarian University (Sonyachna St.3, Vinnytsia, 21008, Ukraine e-mail: email@example.com).
Improving the reliability and service life of machines, components, units is an important factor in reducing the cost of restoration, downtime of equipment in repair, reducing the number of spare parts.
The introduction of the latest technologies of agricultural production, as well as constant modern improvement, the complexity of agricultural machinery is a natural result of its development.
Parts restoration technologies are among the most resource-saving, because compared to the manufacture of new parts costs are reduced by up to 70%. The main source of resource savings is the cost of materials.
At longtime use of machines wear of details is followed by decrease in operational indicators, causes deterioration of quality of products.
The tractor PTO shaft is subjected to significant static and dynamic loads. The high wear rate is due to constant friction with the grafting disc, gear, inner bearing rings. The production of a new power take-off shaft requires significant costs, so the development of new technological processes of repair and restoration is relevant.
It is rational at restoration of the previous sizes and return of a detail of normal mechanical properties. The remanufactured part is consuming its life, like a new part, and may exceed the service life of the new part.
With the increase in the equipment of agricultural production with more advanced equipment, the conduct of complex mechanization and increasing the efficiency of the use of equipment, repair production is developing and changing. The development of the field of restoration of worn parts is based on close cooperation of repair production with branch and basic science, and achievement of scientific and technical progress.
A promising direction of restoration technology in the organizational plan is the deepening of the method of group restoration technology - the creation of a unified group equipment for the restoration of surfaces. It is established that the majority of details of the restored cars are rejected at the expense of insignificant wear of working surfaces, making no more than 1% of initial weight of details. Experiments and practice show that the repair of agricultural machinery is technically impossible to avoid. Most worn parts have a high residual value: their restoration consumes 20-30 times less metal and materials than the manufacture of new ones, which is economically feasible.
Problems are considered: the choice of technological process of restoration, the choice of technological equipment, tools.
