Description
(54) СПОСОБ ВОССТАНСеЛЕНИЯ ИЗНСШЕННЫХ ДЕТАЛЕЙ (54) METHOD OF RESTORING EXHAUSED PARTS
1one
Изобретение относитс к судоремонту, а именно к ремонту топливных насосов высокого давлени (1НВД) судовых дизелей , предназначено, в частности, дл восстановлени изношенных плунж ных пар ТНВД на судоремонтных гредгфи - ти х различных ведомств, и может быть использовано дл восстановлени других изношенных деталей цилиндрической формы.The invention relates to ship repair, in particular to the repair of high pressure fuel pumps (1NVD) of marine diesel engines, in particular, for restoring worn plunger injection pump pairs at various ship repair facilities, and can be used to repair other worn cylindrical parts forms.
Известны способы восстановлени изношенных деталей, состо щие из операций пористого хромировани и абразивной обработки с применением смазочно-охлаждающей жидкости ij.Methods are known for restoring worn parts, consisting of porous chrome plating and abrasive operations using coolant ij.
Недостатком известных способов вл етс низкое качество восстановлени изношенных деталей.A disadvantage of the known methods is the low quality of repairing worn parts.
Цель изобретени - повышение качества восстановлени изношенных деталей.The purpose of the invention is to improve the quality of restoring worn parts.
Поставленна цель достигаё тс тем, что одновременно с абразивной обработкой гфоизвод т выглаживание восстанавливаемых поверхностей алмазными брусками. ЦИЛИНДРИЧЕСКОЙ ФОРМЫThe goal is achieved by the fact that, simultaneously with the abrasive treatment, the smoothing of the surfaces being repaired with diamond bars is carried out. CYLINDRICAL FORM
подачу которых выбирают в пределах О,О8-О,12 мм/об.the flow of which is chosen in the range of O, O8-O, 12 mm / rev.
Этот способ, относ щийс к детал м, восстанавливаемых пористым-хромированием , позвол ет уменьщить шероховатость офаботанной поверхности, повысить твердость поверхностного сло . Ущзочненив деталей, восстанавливаемых Бористым хромированием , поверхностным пластическим дефс мированием вл етс эффективным This method, related to parts repaired by porous-chromium plating, makes it possible to reduce the roughness of the surface and increase the hardness of the surface layer. Improving the parts restored by Borista chromium plating with surface plastic repair is effective.
10 средством повышени их обшей фочностн и снижени скорости роста трещин.10 means of increasing their overall fairness and reducing the rate of crack growth.
Остаточные напр жени сжати , возникающие в поверхностном слое детали 1ФИ алмазном выглаживании, оказывают The residual compressive stresses arising in the surface layer of the 1-FD diamond smoothing part have
и существенное вли ние на развитие тре-щин . Происходит значительное увеличение срока службы деталей за счет более медленного роста трещин, как по периферии, так и по глубине у1фочненного сло .and a significant impact on the development of cracks. There is a significant increase in the service life of parts due to the slower growth of cracks, both in the periphery and in the depth of the first layer.
