Luyini uhlobo lwe-bearing evaliwe, uhlobo lwe-bearing seal

 

I-bearing ebizwa ngokuthi i-sealed bearing iyi-bearing engangeni uthuli, ukuze i-bearing ivalwe kahle ukuze i-bearing igcine izimo ezibushelelezi kanye nendawo yokusebenza evamile, inike ukusebenza okugcwele kwe-bearing, yandise impilo yesevisi ye-bearing, futhi ibe ne-seal efanelekile ye-bearing egoqayo ukuze kugwenywe ukuvuza kwe-ejenti ebushelelezi kanye nokuhlasela kothuli, umhwamuko wamanzi noma olunye ukungcola. Lokhu kusiza ekuvikelweni kwe-bearing.

 

Uhlobo Lokufaka Uphawu:

TIsakhiwo sedivayisi yokuvala ama-rolling bearings sihlukaniswe kakhulu ngezimpawu zokuxhumana kanye nezimpawu ezingezona ezokuxhumana.

 

Ukuvalwa kwama-bearings okungenakuthintana

 

Ukuvala i-bearing non-contact kuyindlela yokuvala eklama igebe elincane phakathi kwe-shaft kanye nesembozo sokugcina sendlu yokubeka i-bearing. Lolu hlobo lwesakhiwo sokuvala aluthinti i-shaft, ngakho-ke akukho ukungqubuzana nokuguguleka, futhi lufanelekela ukujikeleza ngesivinini esikhulu. Ukuze kuthuthukiswe umphumela wokuvala, igebe lingagcwaliswa ngamafutha. I-bearing non-contact seals ihlanganisa ikakhulukazi: i-gap seal, i-oil groove seal, i-labyrinth seal, i-oil slinger seal, njll.

 

1. Ukuvala izikhala

I-gap seal kufanele ishiye igebe elincane eli-annular phakathi kwe-shaft kanye nesembozo se-bearing ngokusebenzisa imbobo, igebe le-radius lingu-0.1-0.3mm, uma igebe lide futhi lincane, umphumela wokuvala uba ngcono.

 

2. Ukuvalwa kwe-groove kawoyela

 

I-oil groove seal icutshungulwa nge-annular oil groove ephephabhukwini lengaphakathi lesembozo sokugcina uphawu lokuthwala, kanti i-oil guide groove isatshalaliswa ngemisebe, futhi i-annular oil ngayinye ixhumana nge-oil guide groove futhi ixhumana nethangi likawoyela, futhi inani le-annular oil groove kanye ne-oil guide groove linqunywa ngobukhulu besembozo sokugcina uphawu.

 

3. Ukuvalwa kwe-labyrinth

Isimiso esiyisisekelo salokhu kuvalwa ukudala isiteshi sokugeleza esivalweni ngokumelana okukhulu kokugeleza. Ngokwesakhiwo, kwakheka igebe elincane eligobile phakathi kwengxenye engashukumi nengxenye ejikelezayo ukuze kwakheke "i-labyrinth".

 

4. Ukuvalwa kwe-oyili slinger

 

Izimbozo zokuthintana zamabheringi

Ukuvala ngocingo kuyindlela yokuvala yomshini wokuxhumana wokugcina noma wezindebe ngerabha yokwenziwa eyenziwe nge-vulcanized ku-skeleton yensimbi, futhi ukusebenza kwayo kokuvala kungcono kunokuvala ngocingo olungenakho ukuxhumana, kodwa ukungqubuzana kukhulu, futhi izinga lokushisa liphakeme kakhulu. Indawo yokuxhumana yomshini kanye nophawu idinga ukugcotshwa, ngokuvamile nge-lubricant efanayo ne-bearing. Izimpawu zokuxhumana zifaka phakathi: ukuvala ngendandatho ye-felt, ukuvala ngebhodlela lesikhumba, ukuvala ngendandatho yokuvala, ukuvala ngendandatho ye-skeleton, ukuvala ngendandatho yokuvala, njll.

 

1. Ukuvalwa kwendandatho ye-Felt

Kuvulwa umsele we-trapezoidal esembozweni sebheyi, bese kuthi i-felt encane yengxenye engunxande ibekwe emseleni we-trapezoidal ukuze ithintane nomgodi, noma i-gland icindezelwe nge-axial ukuze indandatho ye-felt icindezelwe futhi ikhiqize ingcindezi ye-radial ukuze iyibambe emseleni, ukuze kufezwe injongo yokuvala.

 

2.Isitsha sesikhumba sivaliwe

 

Isitsha sesikhumba esivaliwe (esakhiwe ngezinto ezifana nerabha edonswa uwoyela) sifakwa esembozweni sebheyi bese sicindezelwa ngqo emshafini. Ukuze kuthuthukiswe umphumela wokuvala, kucindezelwa isiphethu sekhoyili yendandatho engaphakathi kwesitsha sesikhumba, ukuze indandatho engaphakathi yesitsha sesikhumba ivumelane kakhulu nomshafini..

 

3. Indandatho yokuvala ivaliwe

Izivalo zivame ukwenziwa ngesikhumba, ipulasitiki noma irabha engangeni uwoyela futhi zingenziwa ngamaphrofayili ahlukene njengoba kudingeka. Indandatho yokuvala enobunjwa obungu-0 inephrofayili eyindilinga, ithembele emandleni ayo okunwebeka ukuze icindezele emshaft, ngesakhiwo esilula kanye nokuhlanganiswa okulula nokuhlukaniswa. Izivalo ezinobunjwa obungu-J kanye no-U nazo zivame ukusetshenziswa, zombili ezinesakhiwo esinobunjwa obungu-lip.

 

4. Ukuvalwa kwamathambo

 

Ukuze kuthuthukiswe amandla aphelele esivalo sesitsha sesikhumba, ulwelwesi lwensimbi olunengxenye evundlile enomumo we-L kanye nesimo se-annular lufakwa ngerabha engangeni uwoyela, ukuze uphawu lwesitsha sesikhumba kungabi lula ukulushintsha, futhi impilo yenkonzo ithuthuke. Endabeni ye-<7m/s, iningi lamabhokisi okuthwala iphampu ye-centrifugal okwamanje livalwe ngohlaka.

 

5. Ukuvalwa kwendandatho yokuvala

Lolu uhlobo lophawu oluhlanganisiwe olune-notch, lufakwa emseleni wendandatho wesikhafu, isikhafu sijikeleza kanye nomgodi, futhi indandatho yokuvala icindezelwa odongeni lwembobo yangaphakathi yengxenye engashukumi ngenxa yokuqina kwe-notch ecindezelwayo, futhi ingadlala indima yokuvala, futhi lolu hlobo lokuvala luyinkimbinkimbi kakhulu.

 

Ukukhethwa kwesakhiwo sophawu lokuthwala

 

Uma ukhetha isakhiwo sesivalo sokuthwala, izici eziyinhloko okufanele uzicabangele yilezi: i-lubricant, okungukuthi, kungaba uwoyela noma i-grease; Ijubane eliqondile lezingxenye zokuvala; iphutha lokufakwa kwe-shaft; Usayizi kanye nezindleko zendawo yokufaka, njll.
