Mosebetsi oa Bearings
Li-bearings tsa borokho li sebelisetsoa ho fetisetsa matla ho tloha mohahong o moholo ho ea mohahong o ka tlaase, ho lumella mefuta e latelang ea metsamao ea superstructure: Metsamao ea phetolelo;li kheloha ka litsela tse otlolohileng le tse tšekaletseng ka lebaka la matla a sefofane kapa a tsoang kantle ho sefofane joalo ka moea le boima ba 'mele.Metsamao ea ho potoloha;lebaka ka baka la nako.Ho fihlela bohareng ba lekholo lena la lilemo, li-bearings tse neng li sebelisoa li ne li e-na le mefuta e latelang:
· Pin
· Rolara
· Rocker
· Metal sliding libering
Pin bearing ke mofuta oa li-bearings tse tsitsitseng tse amohelang lipotoloho ka tšebeliso ea tšepe.Liphetoho ha lia lumelloa.Pini e kaholimo e entsoe ka libaka tse kaholimo le tse tlase tse hahelletsoeng ka semicircular tse nang le phini e tiileng ea selikalikoe lipakeng.Hangata, ho na le likatiba lipheletsong tse peli tsa phini ho thibela phini hore e se ke ea thella litulo le ho hanela meroalo ea ho phahamisa ha ho hlokahala.Letlapa le ka holimo le hokahantsoe le poleiti e le 'ngoe ka ho bolting kapa ho cheselletsa.Letlapa le kobehileng le tlase le lutse holim'a poleiti ea masonry.Rotational Movement e lumelletsoe.Metsamao ea morao-rao le ea ho fetolela e thibetsoe.
Mefuta ea Roller Bearings
Bakeng sa lits'ebetso tsa ho itšehla thajana ho itšehla thajana ho mochini, ho sebelisoa lirolara le ho beha bolo.E kenyelletsa li-roller tsa cylindrical le libolo.Ho lekane ho hanela metsamao ea lits'ebeletso le damping ho latela thepa e sebelisoang.
AASHTO e hloka hore lirolara tse atolositsoeng li be le "li-bars tse kholo tsa mahlakoreng" 'me li tataisoe ke gearing kapa mekhoa e meng ea ho thibela motsamao oa lateral, skewing, le creeping (AASHTO 10.29.3).
Tloaelo e akaretsang ea mofuta ona oa ho jara ke tšekamelo ea ho bokella lerōle le lithōle.Ho sisinyeha ha longitudinal ho lumelloa.Metsamao ea Lateral le Lipotoloho li thibetsoe.
Mofuta oa Rocker Bearing
Rocker bearing ke mofuta oa katoloso o tlang ka mefuta e mengata e fapaneng.Hangata e na le phini ka holimo e thusang ho potoloha, le sebaka se kobehileng ka tlase se amohelang metsamao ea phetolelo.Li-rocker le li-pin li sebelisoa haholo ka marokho a tšepe.
Sliding Bearings
Letlapa le thellang le sebelisa poleiti e le 'ngoe ea tšepe e thellisang ho e 'ngoe ho amohela liphetolelo.The sliding bearing surface e hlahisa matla a khohlano a sebelisoang ho superstructure, substructure, le bearing ka boeona.Ho fokotsa matla ana a khohlano, PTFE (polytetrafluoroethylene) hangata e sebelisoa e le thepa e thellang.PTFE ka linako tse ling e bitsoa Teflon, e reheletsoeng ka mofuta o sebelisoang haholo oa PTFE.Sliding Bearings e ka sebelisoa e le mong kapa hangata e sebelisoa e le karolo ea mefuta e meng ea libere.Li-bearings tse hloekileng tse thellang li ka sebelisoa feela ha ho potoloha ho bakoang ke ho kheloha ho litšehetso ho sa tsotellehe.Ka hona li lekanyelitsoe ho bolelele ba bolelele ba limithara tse 15 kapa ka tlase ho ASHTTO [10.29.1.1]
Sistimi ea ho thella e nang le coefficient e boletsoeng esale pele ea khohlano e ka fana ka khethollo ka ho fokotsa lebelo le matla a fetisoang.Li-slider li khona ho fana ka khanyetso tlas'a maemo a ts'ebeletso, ho feto-fetoha ha maemo le ho falla ka matla ka ho thella.Hangata li-slider tse nang le sebopeho kapa tse chitja li ratoa ho feta litsamaiso tse thellang tse bataletseng ka lebaka la ts'ebetso ea tsona ea ho khutlisa.Li-slider tse bataletseng ha li na matla a ho khutlisa hape ho na le menyetla ea ho falla ka litšisinyeho tse latelang.
Knuckle Pinned Bearing
Ke mofuta o ikhethileng oa Roller Bearing eo ho eona ho fanoang ka Pini ea Knuckle bakeng sa ho sisinyeha habonolo.Pini ea knuckle e kenngoa pakeng tsa ho lahla holimo le tlase.Ho lahla holimo ho hoketsoe ho sebopeho se seholo sa Bridge, ha karolo e ka tlase e lutse holim'a letoto la lirolara.Knuckle pin e ka amohela metsamao e meholo mme e ka amohela ho thella le ho potoloha
Pitsa Bearings
POTEKA e na le silindara ea tšepe e sa tebang, kapa pitsa, holim'a axis e otlolohileng e nang le "neoprene disk" e mosesane hanyane ho feta silinda mme e kenngoe ka thata ka hare.Piston ea tšepe e kenella ka har'a silinda le libere ho neoprene.Masale a koporo a bataletseng a sebelisetsoa ho tiisa rabara pakeng tsa piston le pitsa.Rabara e sebetsa joalo ka mokelikeli oa viscous o phallang ha ho potoloha ho ka etsahala.Kaha ho beleha ho ke ke ha hanela nako ea ho kobeha, e tlameha ho fanoa ka setulo sa borokho se lekanang.
Plain Elastomeric Bearings (Sheba PPT)
Laminated Elastomeric Bearings
Li-bearings tse entsoeng ka likarolo tse rapameng tsa rabara ea maiketsetso kapa ea tlhaho ka likarolo tse tšesaane tse tlanngoeng pakeng tsa lipoleiti tsa tšepe.Li-bearings tsena li khona ho tšehetsa meroalo e holimo e emeng e nang le mefokolo e nyane haholo.Li-bearings tsena lia tenyetseha tlas'a meroalo ea lateral.Lipoleiti tsa tšepe li thibela likarolo tsa rabara hore li se ke tsa phunyeha.Ho fanoa ka li-lead cores ho eketsa matla a ho phophoma kaha li-elastomeric bearings li sa fane ka pholiso e kholo.Hangata li bonolo ka lehlakoreng le tšekaletseng 'me li thata ho ea holimo.
E na le lesela la laminated elastomeric le nang le silindara e etellang pele bohareng ba bere.Mosebetsi oa karolo ea rabara-tšepe ea laminated ea ho jara ke ho jara boima ba sebopeho le ho fana ka elasticity ka mor'a lihlahisoa.The lead core e etselitsoe ho holofala ka polasetiki, ka hona e fana ka phokotso ea matla a mongobo.Li-rabara tse nang le loto li sebelisoa libakeng tse nang le litšisinyeho tsa lefatše ka lebaka la ts'ebetso ea tsona tlas'a litšisinyeho tsa lefatše.
