Description

Pierwszenstwo: 11.03.1972 (P. 154002) Zgloszenie ogloszono: 31.05.1973 Opis patentowy opublikowano: 28.02.1975 75129 KI. 47f2,15/32 MKP F16j 15/32 Twórcy wynalazku: Waclaw Blachnio, Tadeusz Michel, Krzysztof Gilewicz Uprawniony z patentu tymczasowego: Akademia Rolnicza, Lublin (Pol¬ ska) Uszczelka Przedmiotem wynalazku jest Uszczelka do riisikJo- cisnieniowyóh zlacz hydraulicznych kojarzonych Obrotowo.Stosowane dotychczas uszczelki fibrowe do nisko- cisnieniowych zlacz hydraulicznych kojarzonych obrotowo mialy bardzo prosta komstnulkicje. Stano¬ wily je plaskie pierscienie, wkladane miedzy dwa elementy kojarzone obrotowo. , Takie rozwiazanie posiada szereg wad. Najwiek¬ sza wada jest nietrwalosc uszczelki, która podczas kojarzenia musi przeniesc bardzo duze naprezenia skrecajace. Taka uszczelka nie stanowi niezawod¬ nego uszczelnienia i bardzo czesto powoduje przecieki. Poza tym dla dokladnego uszczelnienia nalezy stosowac duze sily dociskajace, co nieraz powoduje uszkadzanie dokrecanych elementów.Celem wynalazku jest zaiprojekitawainie uszczelki, która bylaby trwalsza od opisanej, niezawodna w uzytkowaniu i nie potrzebowala bardzo duzych sil dociskajacych.Wytyczony cdi zrealizowano przez zaprojektowa¬ nie uszczelki, skladajacej sie z dwóch pierscieni fibrowych i dwóch pierscieni tetflonowych, ksztal- itam dopasowanych do powierzchni bocznych piers¬ cieni fibrowych, wlozonych miedzy dwa kojarzone obrotowe elementy zlacza w kolejnosci: pierscien fibrowy, dwa pierscienie teflonowe, pierscien fib¬ rowy.Dzieki takiemu rozwiazaniu uszczelki, podczas kojarzenia element wkrecany powoduje obrót sty¬ lo 15 Z kaljacego sie z nim pierscienia filbrowego oraz jed¬ nego pierscienia teflonowego, zas drugi pierscien teflonowy i drugi pierscien fibrowy pozostaja w bezruchu zwiazane silami tarcia z czescia nie ob¬ racajaca sie. Skutkiem tego elementy zaprojektowa¬ nej uiszczellki nie przenosza duzych naprezen skrecaljacyich, sa wiec trwafllsze, dzieki 'Wiekszej sprezystosci lepiej uszczelniaja i nie wymagaja bardzo duzej sdly docisku.Przyfklad wytoonania pokazano na rysunku. Za¬ projektowana uszczelke uzyto tutaj do zlacza pafli- wowego instalacji zasilania saffnochodu.Miedzy lbem srulby drazonej 3 a elementem do¬ prowadzajacym 4 znajduja sie dwa pierscienie fib¬ rowe 1 i dwa pierscienie z teflonu 2 usytuowane w nastepujacej kolejnosci: pierscien fibrowy, dwa pierscienie z teflonu, pierscien fibrowy. PLPriority: March 11, 1972 (P. 154002) Application announced: May 31, 1973 Patent description was published: February 28, 1975 75129 KI. 47f2,15 / 32 MKP F16j 15/32 Inventors: Waclaw Blachnio, Tadeusz Michel, Krzysztof Gilewicz Authorized by the provisional patent: Agricultural University, Lublin (Poland) Gasket The subject of the invention is a gasket for hydraulic couplings associated in Rotation. hitherto, fiber seals for low-pressure rotary couplings have been very simple. They were flat rings inserted between two pivoting elements. Such a solution has a number of disadvantages. The greatest disadvantage is the instability of the gasket, which must transfer very high torsional stresses during mating. Such a gasket does not provide a reliable seal and causes leakage very often. In addition, for accurate sealing, high pressing forces must be used, which sometimes causes damage to the screwed elements. The aim of the invention is to design a gasket that would be more durable than the described one, reliable in use and do not require very high pressing forces. consisting of two fiber rings and two tetflon rings, shape matched to the side surfaces of fiber rings, inserted between two associated rotating elements of the joint in the following order: a fiber ring, two Teflon rings, fiber rings. during mating, the screw-in element causes the rotation of style 15 from a sagging felt ring and one Teflon ring, while the other Teflon ring and the other fiber ring remain motionless, bound by the frictional forces of the non-rotating part. As a result, the elements of the designed pipe do not transmit high torsional stresses, so they are more durable, due to their greater elasticity, they seal better and do not require a very large clamping force. An example of the groove is shown in the figure. The designed gasket was used here for the waffle joint of the saffron feed system. Between the head of the hollow fiber 3 and the guide element 4 there are two fiber rings 1 and two Teflon rings 2 located in the following order: fiber ring, two rings made of Teflon, fiber ring. PL
