                Jak ka\u017cda inna cz\u0119\u015b\u0107 samochodowa, tuleje wahaczy z czasem ulegaj\u0105 zu\u017cyciu. Powoduje to wzrost uci\u0105\u017cliwych wibracji, kt\u00f3re w skrajnych przypadkach mog\u0105 by\u0107 niebezpieczne. Tuleje w wahaczach r\u00f3wnie\u017c ulegaj\u0105 zu\u017cyciu z powodu obci\u0105\u017ce\u0144, jakie na nie wywieraj\u0105 ekstremalne warunki jazdy. Dodatkowo, czynniki \u015brodowiskowe i opony o zbyt du\u017cym rozmiarze przenosz\u0105 wi\u0119cej wibracji przez tuleje ni\u017c opony o konwencjonalnych rozmiarach. Niezale\u017cnie od przyczyny, tuleje mog\u0105 by\u0107 \u017ar\u00f3d\u0142em wielu problem\u00f3w.

                G\u0142\u00f3wn\u0105 przyczyn\u0105 p\u0119kania suchych tulei zaworowych jest niedopasowanie rozszerzalno\u015bci cieplnej rdzenia i ko\u0142nierza. Taka sytuacja mo\u017ce powa\u017cnie zagrozi\u0107 bezpiecze\u0144stwu systemu elektroenergetycznego. Aby poprawi\u0107 bezpiecze\u0144stwo suchych tulei zaworowych, zbadano rozw\u00f3j p\u0119kni\u0119\u0107 papieru impregnowanego \u017cywic\u0105 epoksydow\u0105 w r\u00f3\u017cnych warunkach. Do badania procesu p\u0119kania wykorzystano r\u00f3wnie\u017c sprz\u0119\u017cony model symulacji termomechanicznej.
                Pierwszym krokiem w diagnozie przyczyny zu\u017cycia i p\u0119kni\u0119\u0107 tulei jest kontrola wizualna. Tuleja wahacza dolnego jest przymocowana do ramy za pomoc\u0105 wspornika. Je\u015bli widoczne s\u0105 p\u0119kni\u0119cia, nale\u017cy wymieni\u0107 tulej\u0119. Nie ma jednak konieczno\u015bci wymiany ca\u0142ego zawieszenia. W niekt\u00f3rych przypadkach zu\u017cyte tuleje mog\u0105 powodowa\u0107 r\u00f3\u017cne problemy, takie jak przechylanie si\u0119 nadwozia, nadmierne zu\u017cycie opon i ha\u0142as podczas pokonywania zakr\u0119t\u00f3w.<\/p>\n

                Je\u015bli rozwa\u017casz zastosowanie bezobs\u0142ugowych tulei obrotowych do swojego kolejnego sworznia obrotowego, zastanawiasz si\u0119, na co zwr\u00f3ci\u0107 uwag\u0119. Tuleja chroni obudow\u0119 przed korozj\u0105 i utrzymuje j\u0105 pod ci\u015bnieniem. Jednak wielu u\u017cytkownik\u00f3w nie zdaje sobie sprawy z tego, jak te komponenty mog\u0105 si\u0119 sprawdzi\u0107 w ich zastosowaniach. W tym artykule przyjrzymy si\u0119 kilku przyk\u0142adom ca\u0142kowicie bezobs\u0142ugowych sworzni obrotowych i om\u00f3wimy ich wymagania.
                Jednym z najpopularniejszych typ\u00f3w tulei bezobs\u0142ugowych s\u0105 tuleje ko\u0142nierzowe i r\u00f3wnoleg\u0142e. W przeciwie\u0144stwie do tulei przek\u0142adni \u015blimakowych, te samosmaruj\u0105ce \u0142o\u017cyska metalowe idealnie nadaj\u0105 si\u0119 do r\u00f3\u017cnorodnych zastosowa\u0144 i warunk\u00f3w. Zmniejszaj\u0105 koszty awarii i przestoj\u00f3w, zapewniaj\u0105c jednocze\u015bnie d\u0142ugotrwa\u0142e smarowanie wymagane przez inne typy tulei. Poniewa\u017c tuleje te s\u0105 wykonane z materia\u0142u bezo\u0142owiowego, s\u0105 zgodne z dyrektyw\u0105 RoHS, co oznacza, \u017ce \u200b\u200bs\u0105 przyjazne dla \u015brodowiska. Innym popularnym typem tulei bezobs\u0142ugowych jest tworzywo sztuczne. Materia\u0142 ten jest \u0142atwiej dost\u0119pny w sprzeda\u017cy i stosunkowo niedrogi w produkcji. Nie nadaje si\u0119 jednak do zastosowa\u0144 wymagaj\u0105cych du\u017cych obci\u0105\u017ce\u0144, poniewa\u017c p\u0119ka pod du\u017cym obci\u0105\u017ceniem i uszkadza wsp\u00f3\u0142pracuj\u0105ce cz\u0119\u015bci. Tworzywa sztuczne mog\u0105 r\u00f3wnie\u017c odbiega\u0107 od normy, je\u015bli proces produkcji jest niedok\u0142adny. Tuleje plastikowe r\u00f3wnie\u017c mog\u0105 p\u0119ka\u0107 pod wp\u0142ywem du\u017cych obci\u0105\u017ce\u0144.

                W przypadku stosowania tulei samosmaruj\u0105cych nie ma potrzeby smarowania.

B\u0119dziesz wdzi\u0119czny za okazan\u0105 \u017cyczliwo\u015b\u0107.

Tuleje samosmaruj\u0105ce mog\u0105 by\u0107 stosowane w \u015brodowiskach o wysokich temperaturach i agresywnych mediach. Produkty te wytrzymuj\u0105 r\u00f3wnie\u017c ogromne ci\u015bnienie. Podczas stosowania tulei samosmaruj\u0105cych wa\u017cny jest dob\u00f3r odpowiedniego materia\u0142u.
                G\u0142\u00f3wn\u0105 zalet\u0105 stosowania tulei samosmaruj\u0105cych jest \u0142atwo\u015b\u0107 konserwacji. Nie wymagaj\u0105 one oleju do pracy i s\u0105 ta\u0144sze w zakupie.

Natomiast chrz\u0105stka w\u0142\u00f3knista zawiera wi\u0119cej kolagenu ni\u017c chrz\u0105stka szklista.

Zewn\u0119trzna, twarda warstwa ko\u015bci to ko\u015b\u0107 g\u0119sta, a wewn\u0119trzna warstwa jest g\u0105bczasta, zawieraj\u0105ca szpik kostny, naczynia krwiono\u015bne, nerwy itp. Ko\u015b\u0107 zawiera zar\u00f3wno substancje organiczne, jak i nieorganiczne, a proces twardnienia macierzy prowadzi do jej powstania. Z kolei chrz\u0105stka sk\u0142ada si\u0119 z chondrocyt\u00f3w i macierzy z\u0142o\u017conej z w\u0142\u00f3kien kolagenu i elastyny.

Ponadto tkanka \u0142\u0105czna sk\u0142ada si\u0119 z kom\u00f3rek, w\u0142\u00f3kien i macierzy.
                Podstawowym sk\u0142adnikiem chrz\u0105stki jest siarczan chondroityny, pozyskiwany ze zwierz\u0105t. Chocia\u017c chrz\u0105stka ro\u015bnie wolniej ni\u017c ko\u015b\u0107, jej mikrostruktura jest mniej zorganizowana.
