Description
(54) УПЛОТНИТЕЛЬНАЯ ШАЙБА(54) SEAL WASHER
1one
Изобретение относитс к области машиностроени .The invention relates to the field of engineering.
Известна уплотнительна шайба, содержаш ,а тарельчатый корпус и уплотнительное кольцо из пластичного материала, контактируюш ,ее своей опорной поверхностью с детальюKnown sealing washer, containing, and the disk housing and the sealing ring of plastic material, in contact, its bearing surface with the part
удлинении резьбового стержн под действием температуры шайба должна, не наруша герметичности соединени , компенсировать образуюшиес зазоры. Однако известна шайба из-за недостаточной упругости пластичного материала неудовлетворительно герметизирует соединение. the elongation of the threaded rod under the action of the temperature of the washer must, without violating the tightness of the joint, compensate for the gaps. However, the known washer due to insufficient elasticity of the plastic material unsatisfactory seals the connection.
В предлагаемой уплотнительной шайбе дл повышени ее упругих свойств с целью обеспечени посто нного нат га в резьбовом соединении крепежных деталей тарельчатый корпус выполнен с расположенными по его периферии подогнутыми лепестками, частично охватывающими уплотнительное кольцо со стороны его опорной поверхности.In the proposed sealing washer, in order to increase its elastic properties in order to ensure constant tension in the threaded connection of fasteners, the disk-shaped body is provided with bent petals located on its periphery, partially covering the sealing ring on the side of its supporting surface.
На фиг. 1 представлена предлагаема шайба , продольный разрез; на фиг. 2 - вид по стрелке А на фиг. 1.FIG. 1 shows the proposed washer, longitudinal section; in fig. 2 is a view along arrow A in FIG. one.
Шайба состоит из тарельчатого корпуса 1 с подогнутыми лепестками 2, расположенными по его периферии со стороны его опорной поверхности. Лепесткп частично охватывают уплотнительное кольцо 3.The washer consists of a dish-shaped body 1 with folded petals 2 located along its periphery on the side of its supporting surface. Petals partially cover the sealing ring 3.
При зат гивании резьбового соединени лепестки подгибаютс и сжимают уплотнительиое кольцо. Материал последнего заходит в зазор 4 между стержнем резьбового элемента 5 и деталью 6.When tightening the threaded joint, the petals bend and compress the sealing ring. The material of the latter enters the gap 4 between the stem of the threaded element 5 and the part 6.
При температурном удлинении резьбового элемента лепестки корпуса частично распр мл ютс , высота уплотнительного кольца 3 измен етс и герметизаци соединени не нарушаетс .At temperature elongation of the threaded element, the petals of the housing partly expand, the height of the sealing ring 3 is changed, and the sealing of the joint is not disturbed.
Обшее усилие зат жки Роб дл герметизации соединени будет равно:The total Rob tightening force for sealing the joint will be:
Ро5 Рт+Рп,Ro5 Rt + Pn,
где РШ. - усилие, соответствующее пределуwhere is RS. - force corresponding to the limit
текучестиyield strength
PSI. - усилие, создаваемое подогнутыми лепестками.Psi. - the force created by folded petals.
