Description

Создание гидравлических прессоБ с большими усили ми требует применени  в них надежных уплотнении. При сверхвысоких давлени х в гидроцилиндрах возникает резко выраженное унругое деформирование етенок. Внутренний и наружный диаметры цилиндра под действием давлени  жидкости увеличиваютс , ири этом известные манжетные уплотнительные устройства быстро выход т ii3 стро Описываемое уплотнение цилиндров гидропрессов лии:ено указанного недостатка и срок службы его значительно повышаетс . Это достигаетс  тем, что одна из опор маижеты выполнена в виде размещенного в нажимном фланце разрезного металлического кольца, со скошенной контактируюшей с манжетой поверхностью, одновременно прижимаемого к плунжеру пружиной, расноложе1Н10Й во внешней выточке кольца.The creation of hydraulic presses with great effort requires the use of reliable compaction in them. At ultrahigh pressures, pronounced uniform deformation of the shade appears in the hydraulic cylinders. The inner and outer diameters of the cylinder increase under the effect of the pressure of the fluid, and the known lip seal devices quickly exit ii3. The described seal of the hydraulic press cylinders does not: the indicated deficiency and its service life increases significantly. This is achieved by the fact that one of the mageta supports is made in the form of a split metal ring placed in the pressure flange, with a beveled surface in contact with the cuff, simultaneously pressed to the plunger by a spring, which is located 1N10J in the outer ring undercut.

На фиг. 1 показано онисываемое уплотиенне; на фнг. 2-разрез по АА на фиг. 1.FIG. 1 shows on-line seal; on fng. 2 is a section along AA in FIG. one.

Уплотнение представл ет собой эластичную манжету 1, котора  одним концом опираетс  иа направл юшую втулку 2 в гндроцилнндре 3, а другим - на разрезное кольцо 4, расноложенное в кольцевой выточке прижимного фланца 5. Коитактпруюнда  с манжетоГ поверхность 6 разрезного кольца выполнена иа конус дл  лучшего прижима к манжете. Дл  прижима к плунжеру 7 разрезного кольца во внешней выточке 8 поеледнего размешена нружина 9,The seal is an elastic cuff 1, which at one end rests on the guide sleeve 2 in the windrow 3, and on the other on the split ring 4, which is located in the annular recess of the pressure flange 5. Coitactrund with the cuff surface 6 of the split ring is made cone for a better hold to the cuff. For clamping to the plunger 7 the split ring in the outer groove 8, a spring 9 is placed,
