Description

(54) УПЛОТНЕНИЕ ВРАЩАЮЩИХСЯ ДЕТАЛЕЙ(54) SEALING ROTATING PARTS

1one

Изобретение относитс  к области уплотнительной техники, нашример, к уплотнени м подшипниковых узлов.The invention relates to the field of sealing technology, our example, to seals for bearing assemblies.

Известны щелевые уплотнени  между вращающимис  детал ми. Недостатком их  вл етс  больша  трудоемкость изготовлени  сопр женных детален дл  обеспечени  минимальных зазоров.There are known gap seals between rotating parts. The disadvantage of them is the great complexity of manufacturing the mating details to ensure minimum clearances.

Преимущество насто щего изобретени  состоит в уменьшении трудоемкости и затрат при изготовлении сопр женных деталей, обеспечивающих минимальный зазор.The advantage of the present invention is to reduce the laboriousness and costs in the manufacture of mating parts, providing a minimum gap.

Отличие уплотнени  заключаетс  в том, что уплотнительный элемент выполнен из разм гчаемой под действием тепла трени  пластмассы таким образом, что при изготовлении уплотнительные кромки касаютс  ооверхности детали, а с началом работы оплавл ютс , образу  минимальный зазор.The difference between compaction lies in the fact that the sealing element is made of plastic softened by heat, so that during manufacture the sealing edges touch the surface of the part, and with the start of work they melt to form a minimum gap.

На фиг. 1 изображен пример применени  уплотнени  подшипника; на фиг. 2 показаны в увеличенном .виде уплотнительные элементы уплотнени ; на фи,г. 3 показан пример уплотнени  вала.FIG. 1 illustrates an example of a bearing seal application; in fig. 2 shows an enlarged view of the sealing elements of the seal; on fi g. 3 shows an example of a shaft seal.

Уплотнение состоит из уплотн емых между собой деталей 1 и 2 и уплотнительного элемента 3, имеющего уплотнительные кромки 4, диаметр di которых перед сборкой меньше диаметра da детали 1.The seal consists of parts 1 and 2 being sealed together and a sealing element 3 having sealing edges 4, the diameter of which before assembly is less than the diameter da of part 1.

Работа уплотнени  заключаетс  в следующем .The sealing operation is as follows.

Контакт между уплотнительными кромками 4 и деталью 1 вызывает трение после начала работы подшипника, отчего выдел етс  тепло. Нод действием тепла трени  происходит оплавление кромок 4 и между деталью 1 п кромками 4 образуетс  небольшой зазор.The contact between the sealing edges 4 and the part 1 causes friction after the bearing starts to work, which causes heat to be generated. The action of heat from friction causes the melting of the edges 4 and a small gap is formed between the part 1 and the edges 4.

Формула изобретени Invention Formula Уплотнение вращающихс  деталей, состо щее из закрепленного на одной детали уплотнительного элемента с симметричными кольцевыми кромками, сужающимис  в направлении второй детали и имеющими зазор с ней, о т л и ч а ющ е ее   тем, что, с целью снижени  трудоемкости изготовлени  сопр женных деталей , обеспечивающих минимальный зазор, уплотнительный элемент выполнен из разм гчаемой под действием тепла трени  нластмассы таким образом, что при изготовлении уплотнительные кромки касаютс  поверхности уплотн емой детали.Sealing rotating parts, consisting of a sealing element mounted on one part with symmetrical annular edges, tapering in the direction of the second part and having a gap with it, which is so that, in order to reduce the labor intensity of manufacturing the mating parts In order to ensure minimum clearance, the sealing element is made of heat-softened training material in such a way that, when fabricated, the sealing edges touch the surface of the part being sealed.
