Техническая возможность и экономическая целесообразность ремонта автомобильных агрегатов с восстановлением изношенных деталей

Abstract

Goal – identification of conditions for the economic feasibility of repairing units with the restoration of parts in comparison with the repair based on the use of new parts. Research – techno‑economic methods were used, taking into account the changing cost items for technological operations of repairing automobile units in various versions. The limitation was the provision of after‑repair running hours of repaired units, not inferior to the standard operating time of new units. Score/results – the review shows the conditions under which the main quality indicators in the form of wear resistance and fatigue strength of the restored parts, which determine their durability, are not inferior to the development to the limit state of new parts. Originality/value – the cost of restoring individual parts during the repair of units is 8–60% of the price of new products. The conditions of concentration of production with an increase in its volumes are given, which reduces the complexity of the restoration of parts up to two times.
