Yintoni intsimbi etywiniweyo, uhlobo lwetywina

 

Okubizwa ngokuba yintsimbi etywiniweyo yintsimbi yothuli, ukwenzela ukuba ukuthwala kutywinwe kakuhle ukugcina ukuthwala iimeko ezigudileyo kunye neendawo eziqhelekileyo zokusebenza, ukunika umdlalo opheleleyo kumsebenzi wokuthwala, ukwandisa ubomi benkonzo yokuthwala, kwaye ube nesitywina esifanelekileyo kwi-rolling bear ukuze ugweme ukuvuza kwe-arhente egudileyo kunye nokuhlasela kothuli, umphunga wamanzi okanye olunye ukungcola. Oku kuluncedo ekukhuseleni ukuthwala.

 

Ukuthwala iTywina yeTywina:

TIsakhiwo sesixhobo sokutywina seebheringi eziqengqelekayo sahlulwe ikakhulu ngamatywina oqhagamshelwano kunye nezitywina ezingaqhagamshelwanga.

 

Ukutywinwa okungaqhagamshelwanga kweebheringi

 

Ukuthwala ukutywinwa kokungadibanisi kuyindlela yokutywina eyenza isithuba esincinci phakathi kwe-shaft kunye nesimbozo sokugqibela sendlu yokuthwala. Olu hlobo lwesakhiwo sokutywina aluqhagamshelani ne-shaft, ngoko akukho ngxabano kunye nokugqoka, kwaye ifanelekile ukujikeleza kwesantya esiphezulu. Ukwandisa umphumo wokutywinwa, isithuba singazaliswa ngamafutha. Ukuthwala amatywina angadibananga ikakhulu kubandakanya: i-gap seal, i-oil groove seal, i-labyrinth seal, i-oil slinger seal, njl.

 

1. Ukutywinwa kwesithuba

Ukutywinwa kwe-gap kukushiya i-gap encinci ye-annular phakathi kwe-shaft kunye ne-covering cover ngokusebenzisa umngxuma, i-gap ye-radius yi-0.1-0.3mm, ixesha elide isithuba sincinci kwaye sincinci, ngcono umphumo wokutywinwa.

 

2. Ukutywinwa kwe-oil groove

 

Isitywina se-oil groove sicutshungulwa kunye ne-oyile ye-annular kwijenali yomgodi ongaphakathi wesivalo esinetywina, kwaye i-oyile yesikhokelo isasazwa nge-radially, kwaye ioyile nganye ye-annular inxibelelana nge-oyile yesikhokelo kwaye inxibelelana netanki yeoli. , kunye nenani le-oyile ye-annular kunye ne-oil guide groove inqunywe ngubukhulu besiciko sokugqibela sesitywina.

 

3. Ukutywinwa kweLabyrinth

Umgaqo osisiseko woku kutywinwa kukudala umjelo wokuhamba kwitywina kunye nokumelana okukhulu nokuhamba. Ngokwesakhiwo, i-gap encinci ye-tortuous yenziwa phakathi kwendawo emileyo kunye nenxalenye ejikelezayo ukwenza "i-labyrinth".

 

4. Ukutywinwa kwe-oyile ye-slinger

 

Amatywina oqhagamshelwano kwiibheringi

Ukutywinwa koqhagamshelwano yindlela yokutywina yokuphela okanye i-lip contact shaft yerabha eyenziwe vulcanized kwi-skeleton yensimbi, kwaye ukusebenza kwayo kokutywinwa kungcono kunokokutywinwa okungadibanisiyo, kodwa ukungqubana kukhulu, kwaye ukunyuka kwamaqondo obushushu kuphezulu. Ummandla woqhagamshelwano we-shaft kunye nesitywina kufuneka uthanjiswe, ngokuqhelekileyo kunye ne-lubricant efanayo kunye nokuthwala. Iimpawu zoqhagamshelwano ikakhulu ziquka: ukutywinwa komsesane ozivayo, ukutywinwa kwesitya sesikhumba, ukutywinwa komsesane wokutywina, ukutywinwa kwamathambo, ukutywinwa komsesane, njl.

 

1. Ivalwe ukutywinwa kweringi

I-trapezoidal groove iyavulwa kwisigqubuthelo esithweleyo, kwaye ukuva okucolekileyo kwenxalenye yoxande ibekwe kwi-trapezoidal groove ukuze idibane ne-shaft, okanye idlala licinezelwe nge-axially ukwenza iringi ezivayo icinezelwe kwaye ivelise uxinzelelo lweradial ukuyibamba. ishaft, ukuze kuphunyezwe injongo yokutywinwa.

 

2.Isitya sesikhumba sivaliwe

 

Isitya sesikhumba esitywiniweyo (esenziwe ngezinto ezifana ne-rubber eyenziwe nge-oyile) ifakwe kwi-cover cover kwaye icinezele ngokuthe ngqo kwi-shaft. Ukuze kuphuculwe umphumo wokutywinwa, i-coil spring spring icinezelwe kwindandatho yangaphakathi yesitya sesikhumba, ukwenzela ukuba umsesane wangaphakathi wesitya sesikhumba ube nokuqina okuhambelana ne-shaft..

 

3. Umsesane wokutywina utywinwe

Amatywina ahlala enziwe ngesikhumba, iplastiki okanye irabha enganyangekiyo kwi-oyile kwaye inokwenziwa kwiiprofayili ezahlukeneyo njengoko kufuneka. Umsesane wokutywina owenziwe nge-0 uneprofayili ejikelezayo, exhomekeke kumandla ayo a-elastic ukucinezela kwi-shaft, kunye nesakhiwo esilula kunye nokuhlanganisa okulula kunye nokuqhaqha. Iitywina ezimile okwe-J kunye ne-U nazo zisetyenziswa ngokuqhelekileyo, zombini zinesakhiwo esimise okomlebe.

 

4. Ukutywinwa kwamathambo

 

Ukuze kuphuculwe amandla onke okutywinwa kwesitya sesikhumba, intsimbi yentsimbi ene-L-shaped cross-section kunye ne-annular shape ifakwe kwirabha enganyangekiyo yeoli, ukuze isitywina sesikhumba sesikhumba singabi lula ukonakala, kwaye ubomi benkonzo buphuculweKwimeko ye-<7m/s, uninzi lweebhokisi zempompo ze-centrifugal ngoku zitywinwe nge-skeleton.

 

5. Ukutywinwa komsesane wokutywina

Olu luhlobo lwesitywina se-annular kunye nenotshi, ifakwe kwi-groove ye-sleeve, umkhono ujikeleza kunye ne-shaft, kwaye umsesane wokutywina ucinezelwe kudonga olungaphakathi lomngxuma wengxenye emileyo ngokunyanzeliswa kwe-elasticity. inotshi icinezelwe, kwaye inokudlala indima yokutywina, kwaye olu hlobo lokutywina lunzima ngakumbi.

 

Ukukhethwa kwesakhiwo setywina esithwele

 

Xa ukhetha isakhiwo sokutywinwa, izinto eziphambili zokuqwalasela: i-lubricant, oko kukuthi, ingaba ioli okanye igrisi; Isantya somgca weendawo zokutywina; impazamo yokufakela i-shaft; Ubungakanani kunye neendleko zendawo yokufakela, njl.
