Повышение долговечности мобильной сельскохозяйственной и автотранспортной техники триботехнологиями приработки основных сопряжений деталей двигателей / В. В. Аулин, Т. Н. Замота, С. В. Лысенко // Технічний сервіс агропромислового, лісового та транспортного комплексів : науковий журнал. - 2017. - № 8. - С.55-68.2311-441Xhttps://dspace.kntu.kr.ua/handle/123456789/7280Для реализации триботехнологий приработки и восстановления ресурсоопределяющих сопряжений деталей двигателей СМХТ и АТТ предложена конструкция стенда и разработаны соответствующие режимы приработки. Представлены результаты стендовых и эксплуатационных испытаний экспериментальных, прошедших приработку триботехнологиями, и контрольных, обкатанных по стандартным методикам, двигателей 4Ч11/12,5 и Д-240. Выявлена эффективность триботехнологий приработки и их положительное влияние на технико-экономические показатели двигателя. The essence of the proposed method, electrochemical-mechanical running-in of the main mating parts of engines of mobile agricultural machinery (MAM) and auto transport technics (ATT), is considered. The classification of modes of this method with the indication of the runningin operations in cases of separate single-phase running-in such separate mates as mates of engines, and at jointly three-phase running-in for example of the mating parts of engines is given. The stand for the realization of tribotechnologies of jointly three-phase running-in of the main mating parts of MAM and ATT engines is proposed. Its characteristics are given and the specified operation modes and running-in are indicated. The sketch of jointly three-phase interconnection of the alternating electric current to the engine at running-in is shown. The regimes of accelerated testing on the example of the engine 4Ч11/12,5 are developed. It is shown that the bench testing of experimental engines D-240 compared with the control, tested according to standard methods, have a much higher sealing ability of the cylinder-piston group (CPG), three times reduces blowy into the crankcase, less wear on the piston cup, the gap in the pair "piston groove-ring" has not changed. The decrease of the wear of the running-in of the mate "ring-sleeve" and the conservability of surface porousness of side chrome surface of the ring are detected. During the operation on tractors overhaul life of experimental engines were increased in 3.7 times. It is shown that this occurred by improving the characteristics of surfaces and increasing their wear resistance by the using of the proposed running-in tribotechnologies. Conducted bench and operational tests of MAM and ATT engines have shown that the proposed running-in tribotechnology, applied to their overhaul life determining mates of parts, significantly increase durability.ruприработкасопряжения деталейузлыагрегатыстендобкаткаэксплуатацияресурсдолговечностьмобильная сельскохозяйственная и автотранспортная техникаrunning-in periodpairing of partscomponentsassembliesstandbreak-inoperationresourcedurabilitymobile agricultural machinery and auto transport technicsArticle
