Iyini i-bearing evaliwe, uhlobo lophawu olunophawu

 

Okubizwa ngokuthi i-sealed bear iyinhlangano evimbela uthuli, ukuze ukuthwala kuvalwe kahle ukuze kugcinwe izimo ezibushelelezi kanye nemvelo evamile yokusebenza, ukunikeza ukudlala okugcwele emsebenzini wokuthwala, ukwandisa impilo yesevisi ye-bearing, futhi ube nesigxivizo esifanelekile se-rolling bear ukugwema ukuvuza kwe-ejenti eshelelayo kanye nokuhlasela kothuli, umhwamuko wamanzi noma okunye ukungcola. Lokhu kuhambisana nokuvikelwa kwe-bearing.

 

Uhlobo Lophawu Lokufaka:

TIsakhiwo sedivayisi yokufaka uphawu samabhere agingqayo sihlukaniswe ikakhulukazi ngezimpawu zokuxhumana kanye nezimpawu ezingezona othintana nazo.

 

Ukuvalwa okungaxhunywanga kwama-bearings

 

Ukufaka uphawu olungelona othintana naye kuyindlela yokuvala eklama igebe elincane phakathi kwe-shaft kanye nesembozo sokugcina sezindlu ezithwalayo. Lolu hlobo lwesakhiwo sokubeka uphawu aluxhumani ne-shaft, ngakho-ke akukho ukungqubuzana nokugqoka, futhi kufanelekile ukujikeleza ngesivinini esikhulu. Ukuthuthukisa umphumela wokuvala, igebe lingagcwaliswa ngamafutha. Ukufaka ama-non-contact seals ikakhulukazi kufaka phakathi: i-gap seal, i-oil groove seal, i-labyrinth seal, i-oil slinger seal, njll.

 

1. Ukuvalwa kwegebe

I-gap seal iwukushiya igebe elincane le-annular phakathi kwe-shaft kanye nesembozo sokuthwala ngembobo, igebe le-radius lingu-0.1-0.3mm, isikhathi eside igebe lincane futhi lincane, ngcono umphumela wokuvala.

 

2. Ukuvalwa kwe-oil groove

 

I-oil groove seal icutshungulwa nge-annular oil groove kujenali yomgodi ongaphakathi wekhava yokugcina uphawu, futhi i-oil guide groove isatshalaliswa ngokulinganayo, futhi uwoyela ngamunye we-annular uxhumana nge-groove yomhlahlandlela kawoyela futhi uxhumana nethangi likawoyela. , kanye nenombolo ye-annular oil groove kanye ne-oil guide groove inqunywa ubukhulu besembozo sokugcina uphawu.

 

3. Ukuvalwa kwe-labyrinth

Isimiso esiyisisekelo salokhu kubekwa uphawu ukwakha isiteshi sokugeleza esicini esinokumelana okukhulu nokugeleza. Ngokwesakhiwo, igebe elincane elihlukumezayo liyakhiwa phakathi kwengxenye emile kanye nengxenye ejikelezayo ukuze kwakhiwe "i-labyrinth".

 

4. Ukuvalwa kwe-slinger kawoyela

 

Xhumana nezimpawu zama-bearings

Ukuvala othintana naye kuyindlela yokuvala yesiphetho noma i-lip contact shaft yenjoloba yokwenziwa evundile kuhlaka lwamathambo ensimbi, futhi ukusebenza kwayo kokuvala kungcono kunokovala okungekhona ukuthintana, kodwa ukungqubuzana kukhulu, futhi izinga lokushisa liphezulu uma kuqhathaniswa. Indawo yokuxhumana ye-shaft kanye ne-seal idinga ukugcotshwa, ngokuvamile nge-lubricant efanayo ne-bearing. Izimpawu zokuxhumana ikakhulukazi zihlanganisa: ukuvalwa kwendandatho ezwakele, ukuvala isitsha sesikhumba, ukuvala indandatho, ukuvalwa kwamathambo, ukuvala indandatho, njll.

 

1. Izwa ukuvalwa kwendandatho

I-trapezoidal groove ivulwa phezu kwekhava ethwele, futhi umuzwa ocolekile wengxenye engunxande ufakwa emseleni we-trapezoidal ukuze uthintane nomphini, noma indlala icindezelwa nge-axially ukuze indandatho ezwayo icindezeleke futhi ikhiqize umfutho we-radial ukuze uyibambe. umphini, ukuze kufezwe inhloso yokuvala uphawu.

 

2.Isitsha sesikhumba sivaliwe

 

Isitsha sesikhumba esivaliwe (esenziwe ngezinto ezifana nerabha edonswe ngamafutha) sifakwa embozweni yokuthwala bese sicindezelwa ngqo ku-shaft. Ukuze kuthuthukiswe umphumela wokuvala, isiphethu sekhoyili esiyindandatho sicindezelwa eringini yangaphakathi yesitsha sesikhumba, ukuze indandatho yangaphakathi yesitsha sesikhumba ibe nokulingana okuqinile ne-shaft..

 

3. Indandatho yokuvala ivaliwe

Izigxivizo zivame ukwenziwa ngesikhumba, ipulasitiki noma irabha engazweli uwoyela futhi ingenziwa ngamaphrofayili ahlukene njengoba kudingeka. Indandatho yokuvala enomumo ongu-0 inephrofayili eyindilinga, ethembele kumandla ayo anwebekayo ukuze icindezele ku-shaft, enesakhiwo esilula nokuhlanganisa kalula nokuqaqa. Izigxivizo ezimise okwe-J nezimise okwe-U nazo zivame ukusetshenziswa, zombili zinesakhiwo esimise okwezindebe.

 

4. Ukuvalwa kwamathambo

 

Ukuze kuthuthukiswe amandla aphelele ophawu lwesitsha sesikhumba, ulwelwesi lwensimbi olune-cross-section emise okwe-L kanye ne-annular shape lufakwa kurabha engamelana nowoyela, ukuze uphawu lwesitsha sesikhumba lungabi lula ukonakala, futhi impilo yesevisi ithuthukisiweEndabeni ye-<7m/s, amabhokisi amaningi aphethe iphampu aphakathi nendawo okwamanje avaliwe ngohlaka lwamathambo.

 

5. Ukuvalwa kwendandatho yokubeka uphawu

Lolu uhlobo lophawu lwe-annular olunenotshi, lufakwa endaweni eyindandatho yomkhono, umkhono uzungeza kanye ne-shaft, futhi indandatho yokuvala icindezelwe odongeni lwembobo yangaphakathi yengxenye emile ngenxa yokunwebeka inothi iyacindezelwa, futhi ingadlala indima yokuvala, futhi lolu hlobo lokubeka uphawu luyinkimbinkimbi kakhulu.

 

Ukukhethwa kwesakhiwo se-bearing seal

 

Lapho ukhetha isakhiwo se-bearing seal, izici eziyinhloko okufanele zicatshangelwe yilezi: i-lubricant, okungukuthi, kungakhathaliseki ukuthi amafutha noma amafutha; Isivinini somugqa wezingxenye zokuvala; iphutha lokufakwa kwe-shaft; Usayizi nezindleko zesikhala sokufaka, njll.
