Description
Przedmiotem wynalazku jest kraznik z lozyskami slizgowymi wraz z uszczelnieniem wykonanym z materia¬ lu o malym wspólczynniku tarcia dla przenosników tasmowych i rolkowych stosowanych do transportu materia¬ lów sypkich i przedmiotów.Znane sa wedlug patentu nr 95958 krazniki z lozyskami slizgowymi wykonanymi z materialów o malym wspólczynniku tarcia, których segmenty posiadaja ksztaltowe zakonczenia kolnierzowe. Uszczelnienie kraznika zawierajacego dwusegmentowe lozyska slizgowe wykonane jest z odpowiednio uformowanego kolnierza tworza¬ cego uszczelnienie membranowo-przylgowe zamykajace wspólne gniazdo uszczelniajace. Dwusegmentowe lozy¬ ska slizgowe wykonane sa z materialu o malym wspólczynniku tarcia. Kraznik wedlug wynalazku zawiera dwu¬ segmentowe lozyska slizgowe uszczelniajace wspólpracujace z tulejami lozysk slizgowych osadzonych miedzy cylindrycznymi powierzchniami segmentów lozysk slizgowych uszczelniajacych. Tuleje lozyska slizgowego wykonane sa z materialu o malym wspólczynniku tarcia. Zaleta wynalazku jest znaczne zwiekszenie trwalosci kraznika oraz lepszeuszczelnienie. - Przedmiot wynalazku uwidoczniony w przykladzie wykonania na rysunku fig. 1 - kraznik w przekroju wzdluznym z lozyskiem slizgowym i z lozyskiem slizgowym z uszczelnieniem membranowo-przylgowym.Kraznik sklada sie z stalowego plaszcza 1 polaczonego z segmentem wewnetrznym 4 lozyska slizgowego 3 za pomoca piasty 2 a segment zewnetrzny 5 osadzony jest nieruchomo na osi 6 kraznika.Cylindryczna czesc segmentu wewnetrznego 4 osadzona jest na tulei 9 dodatkowo wprowadzonego miedzy segmenty lozyska slizgowego. Segment zewnetrzny 5 wspólpracuje z tuleja 10 dodatkowo wprowadzonego lozyska slizgowego.Uszczelnienie membranowo-przylgowe 7 kraznika tworzy ksztaltowe zakonczenie kolnierzowe segmentu zewnetrznego 5 uformowanego równolegle do cylindrycznej czesci segmentu lozyska slizgowego 3 tworzac rynne, w której znajduje sie koniec ksztaltowego kolnierza tworzacego pierscien nachylony do cylindrycznej czesci segmentu wewnetrznego 4 pod katem ostrym w kierunku na zewnatrz kraznika i zamykajacego wspólne2 99647 gniazdo uszczelniajace 8. Segmenty lozyska slizgowego 3 oraz lozyska skladajacego sie z tulei 9 i 10 wykonane sa z materialu o malym wspólczynniku tarcia. PLThe subject of the invention is a roller with plain bearings with a seal made of a material with a low coefficient of friction for belt and roller conveyors used for the transport of loose materials and objects. According to the patent No. 95958, wheels with slide bearings made of materials with a low coefficient of coefficient are known. friction, the segments of which have shaped flange ends. The seal of the wheel with two-segment slide bearings is made of a suitably formed flange creating a membrane-rebate seal closing a common sealing seat. Two-segment plain bearings are made of a material with a low coefficient of friction. The roller according to the invention comprises two-segment sealing plain bearings cooperating with plain bearing sleeves mounted between the cylindrical surfaces of the sealing plain bearing segments. The plain bearing bushes are made of a material with a low coefficient of friction. The advantage of the invention is a significant increase in the durability of the rotor and better sealing. - The subject of the invention is shown in an example of the embodiment in Fig. 1 - a roller in a longitudinal section with a plain bearing and a plain bearing with a diaphragm-rebate seal. The roller consists of a steel shell 1 connected to an internal segment 4 of a plain bearing 3 by means of a hub 2 and a segment the outer 5 is mounted immobile on the axis 6. The cylindrical part of the inner segment 4 is mounted on the sleeve 9 additionally inserted between the segments of the plain bearing. The outer segment 5 cooperates with the sleeve 10 of the additionally introduced plain bearing. The diaphragm-rebate seal 7 of the abutment creates a shaped flange ending of the outer segment 5 formed parallel to the cylindrical part of the plain bearing segment 3 forming a gutter in which the end of the cylindrical flange forming an inclined flange is located of the inner segment 4 at an acute angle towards the outside of the idler and closing the joint2 99647 sealing seat 8. The segments of the plain bearing 3 and the bearing consisting of sleeves 9 and 10 are made of a material with a low coefficient of friction. PL
