Description
Изобретение относитс к области двигателестроени .The invention relates to the field of engine building.
Известно уплотнение поршней в цилиндрах двигателей внутреннего сгорани при помощи поршневых колец, например стальных .Known sealing pistons in the cylinders of internal combustion engines using piston rings, such as steel.
Однако срок службы уплотнительных колец невелик, приработка колец длительна, а расход смазочных материалов велик.However, the service life of the sealing rings is small, the running-in of the rings is long, and the consumption of lubricants is high.
Цель изобретени - увеличение продолжительности службы уплотнени , экономии смазочных материалов.The purpose of the invention is to increase the life span of the seal, saving lubricants.
Эта цель достигаетс тем, что в качестве уплотнени поршней в цилиндрах используют кольца из металлокерамики в сочетаНИИ со стальными.This goal is achieved by using rings made of metal-ceramic in combination with steel as a seal for pistons in cylinders.
Кроме того, металлокерамические кольца изготовл ют спеканием порошков железа, 1,8% графита и 2,7% хрома.In addition, cermet rings are made by sintering iron powders, 1.8% graphite and 2.7% chromium.
Такое уплотнение поршней в цилиндрах увеличивает продолжительность его службы , ускор ет приработку и экономит смазочные материалы.Such a piston seal in cylinders increases its service life, accelerates burn-in and saves lubricants.
На фиг. 1 показано уплотнение поршней в цилиндрах новых и капитально отремонтированных двигателей; на фиг. 2 - то же,FIG. 1 shows the piston seal in the cylinders of new and overhauled engines; in fig. 2 - the same
Ё изношенных цилиндрах; на фиг. 3 - вариант выполнени уплотнени по фиг. 1 и 2. Уплотнение поршн 1 в цилиндре 2 осушествл ют при помоши компрессионных металлокерамических колец 3 в сочетании со стальными кольцами 4, используемыми в качестве компрессионных или маслосъемных колец 5 (см. фиг. 1, 2 и 3). Металлокерамические кольца изготовлены путем спекани порошков железа, графита 1,8% и хрома 2,7%.Worn cylinders; in fig. 3 shows an embodiment of the seal of FIG. 1 and 2. The sealing of the piston 1 in the cylinder 2 is carried out with the help of compression cermet rings 3 in combination with steel rings 4 used as compression or oil wiper rings 5 (see Fig. 1, 2 and 3). Metal-ceramic rings are made by sintering iron powders, graphite 1.8% and chromium 2.7%.
