Description

Wynalazek dotyczy walu teleskopo¬ wego ze smarownica, za pomoca której smar doprowadza sie miedzy dwie telesko¬ powo przesuwne czesci walu.Rysunek przedstawia przyklad wyko¬ nania przedmiotu wynalazku w przekroju podluznym, czesciowo w widoku zewnetrz¬ nym.Na rysunku liczba 1 oznacza, wewnetrz¬ na czesc a liczba 2 teleskopowo z nia ze¬ spolona zewnetrzna czesc przedstawionego walu. Przekrój poprzeczny walu moze byc dowolny, np. okragly, kwadratowy, pro¬ stokatny, wieloboczny lub inny. Zewnetrz* na czesc 2 posiada mniej wiecej po srodku swej dlugosci wydrazony pierscien 3 i w jej sciance znajduje sie kilka otworów 4, rozmieszczonych na obwodzie. Na pierscie¬ niu 3 znajduje sie wkretka 5, umozliwiaja¬ ca wytlaczanie smaru wewnatrz smarowni¬ cy. Smarem wypelnia sie wydrazanie pier¬ scienia 3, który otworami 4 wnika miedzy czesci 1 i 2 walu teleskopowego. W ten sposób zostaja jego czesci od srodka po¬ wierzchni slizgowej ku koncom zaopatrzo¬ ne w smar, czyli smar rozprowadza sie w kierunku konców obydwóch czesci walu.Dzieki temu jest nie tylko ulatwiony wza¬ jemny przesuw tych czesci walu, lecz za¬ pobiega sie jednoczesnie wnikaniu kurzu lub innych zanieczyszczen na powierzchnie slizgowe wzglednie usuwa sie takie zanie-czys2cze»ia na zewnatrz. Zmniejsza to zuzycie, a tym samym, niebezpieczenstwo powstawania luzu migdzj^ czesciami walu teleskopowego; W ^celu f wstrzymywania wyciekania smaru na koncu zewnetrznej czesci 2 walu jest na ten koniec zalozony pierscien 6 z zacisnietymi w nim wkladka¬ mi uszczelniajacymi z filcu. Te wkladki sluza takze do usuwania kurzu i innych zanieczyszczen z czasowo wysuwajace} sie wewnetrznej czesci walu. PLThe invention relates to a telescopic shaft with a grease gun, by means of which the lubricant is supplied between two telescopic shaft parts. The drawing shows an example of the object of the invention in a longitudinal section, partly in an external view. In the figure, the number 1 indicates the inside of the shaft. ¬ on the part number 2 is telescoped with it, the outer part of the shaft shown. The cross-section of the shaft may be any, for example, round, square, rectangular, polygonal or otherwise. The outer * in part 2 has a hollow ring 3 approximately in the middle of its length and in its wall there are several holes 4 arranged around the circumference. There is a screw 5 on the ring 3, which enables the lubricant to be expelled inside the lubricator. The grease fills the cavity of the ring 3 which penetrates through the holes 4 between the parts 1 and 2 of the telescopic shaft. In this way, its parts are provided with grease from the center of the sliding surface towards the ends, i.e. the grease is distributed towards the ends of both parts of the shaft. As a result, mutual displacement of these shaft parts is not only facilitated, but also prevents simultaneous ingress of dust or other contaminants on the sliding surfaces or the removal of such contamination to the outside. This reduces the wear and therefore the risk of slack formation on the parts of the telescopic shaft; In order to prevent the leakage of the lubricant, a ring 6 is fitted at the end of the outer part 2 of the shaft with felt sealing inserts clamped therein. These inserts also serve to remove dust and other debris with the inner part of the shaft temporarily protruding. PL

Claims

Claims, 1, Telescopic shaft, characterized in that it is provided with grease nipples, by means of which the lubricant is supplied from the cavities under pressure between two of the other sliding telescopic parts, 2, Wal according to claim 1. 3. The lubricator is located approximately in the middle of the length of the sliding surfaces, 3, Wal according to claims 1 and 2, characterized in that the lubricators consist of a hollow ring surrounding several openings arranged on the circumference of the outer telescopic part shaft, which allow the lubricant to be introduced between the two parts of the shaft, 4, the shaft according to claim 1 - 3f characterized in that the ring protruding into the grease is provided with a screw for exerting pressure on the grease, Hasler A, G, Werke f i r Telephonie und P r a z i s i o n s m e c h a n i k.
