Description

Pierwszenstwo: 12.01.1972 (P. 152888) Zgloszenie ogloszono: 30.05.1973 Opis patentowy opublikowano: 15.04.1975 74628 KI. 60a,15/26 MKP F15b 15/26 Twórca wynalazku: Wieslaw Jankowski Uprawniony z patentu tymczasowego: Kieleckie Zaklady Wyrobów Metalowych, Kielce (Polska) Sposób zabezpieczania pierscienia prowadzacego przed wysunieciem w teleskopowych silownikach hydraulicznych Wynalazek dotyczy sposobu zabezpieczania piers¬ cienia prowadzacego przed wysunieciem w telesko¬ powych isalojwnikach hydraulicznych stosowanych zwlaszcza w pojazdach samochodowych samowyla¬ dowczych.Znany jest sposób zabezpieczenia pierscienia pro¬ wadzacego polegajacy na zapunktowaniu pierscie¬ nia z cylindrem iw kilku punktach na obwodzie. Spo¬ sób ten ze wzgledów wytrzymalosciowych nie spel¬ nia swego zadania i wystepuja przypadki wysunie¬ cia sie pierscienia z cylindra na skutek wysokiego cisnienia oleju.Znane sa równiez sposoby zabezpieczenia polega¬ jace na wprowadzeniu wkreta lub kolka w otwory wykonane w kilku punktach laczacych cylinder z pierscieniem, lub tez na wprowadzeniu gwintowa¬ nego pierscienia ograniczajacego iw górna czesc cy¬ lindra. Sposoby te wprawdzie zabezpieczaja .piers¬ cien przed wypadnieciem, jednak wymagaja duzej pracochlonnosci w montazu i wystepuje niebezpie¬ czenstwo uszkodzenia gladzi cylindra.Celem wynalazku jest usuniecie tych niedogod¬ nosci, czyli wyeliminowanie pracochlonnej obróbki zwiazanej z zabezpieczeniem pierscienia w cylin¬ drze. zgodnie z wynalazkiem sposób zabezpieczania pierscienia przed wysunieciem z cylindra polega na tym, ze uprofiloiwana górna koncówke cylindra za- walcowuje sie dosrodkowo na krawedzi pierscienia prowadzacego. Zawalcowamie to wykonuje sie na znanych .urzadzeniach. Przygotowanie powierzchni cylindra pod zawalcowanie polega na tym, ze górna 10 15 20 25 30 jego czesc zostaje zwezona do maksimum 1/4 pier¬ wotnej grubosci scianki, a /wielkosc promienia wy¬ nosi równiez nie mniej jak 1/4 -tej grubosci.Przyklad sposobu zabezpieczania pierscienia w cy¬ lindrze pokazano na rysunku, na którym fig. 1 .przedstawia przekrój podluzny cylindra z pierscie¬ niem w stanie zabezpieczonym, a fig. 2 szczegól cy¬ lindra z przygotowana powierzchnia pod zawalcowa- nie. Górna czesc cylindra 1 poddana jest obróbce skrawajacej w celu wykonania zwezenia do wielkos¬ ci „a" stanowiacej maksimum 1/4 pierwotnej gru¬ bosci scianki cylindra, a wielkosc promienia „r" wynosi równiez nie mniej jak 1/4 tej grubosci. Po wcisnieciu w tuleje cylindra 1 pierscienia prowa¬ dzacego 2, na znanych urzadzeniach dociska sie prze¬ wezona tuleje 3 na powierzchnie czolowa pierscie¬ nia 4. PL PLPriority: January 12, 1972 (P. 152888) Application announced: May 30, 1973 Patent description was published: April 15, 1975 74 628 KI. 60a, 15/26 MKP F15b 15/26 Inventor: Wieslaw Jankowski Authorized by the provisional patent: Kielce Zaklady Wyrobów Metalowych, Kielce (Poland). Telescopic and hydraulic cylinders used in particular in self-tipping automobiles. There is a known method of securing the guide ring by punching a ring with a cylinder and at several points around the circumference. This method, for strength reasons, does not fulfill its task and there are cases of the ring protruding from the cylinder due to high oil pressure. There are also known methods of securing it by inserting a screw or a pin into holes made at several points connecting the cylinder with a ring, or on the insertion of a threaded limiting ring and in the upper part of the cylinder. Although these methods prevent the breast from falling out, they require a lot of effort in assembly and there is a risk of damage to the cylinder liner. The aim of the invention is to eliminate these inconveniences, i.e. to eliminate the time-consuming treatment related to securing the ring in the cylinder. according to the invention, the method of securing the ring against sliding out of the cylinder consists in that the profiled top end of the cylinder is rolled centrally on the edge of the guide ring. This is done on known devices. Preparation of the cylinder surface for rolling consists in that its upper part is tapered to a maximum of 1/4 of the original wall thickness, and the radius is also not less than 1/4 of its thickness. The method of securing the ring in the cylinder is shown in the drawing, in which Fig. 1 shows a longitudinal section of the cylinder with the ring in the secured condition, and Fig. 2 shows a particular cylinder with a prepared surface for rolling. The upper part of the cylinder 1 is machined to taper to the size "a" being a maximum of 1/4 of the original wall thickness of the cylinder, and the radius "r" is also not less than 1/4 of this thickness. After pressing the guide ring 2 into the cylinder 1 sleeve, the known devices press the indented sleeve 3 against the face of the ring 4. EN EN
