Ukuqhathaniswa kwama-bearings aginqikayo kanye nama-plain bearings

Okokusetshenziswa kweama-bearings, izakhiwo zokungqubuzana zama-bearings akhuphukayo zingahlukaniswa zibe ama-bearings agingqayo kanye nama-sliding bearings, singakhetha izinhlobo ezahlukene zokuthwala ngokuvumelana nezidingo ezithile zokusetshenziswa, ama-rolling bearings nama-sliding bearings anezici ezihlukene zokusetshenziswa,

Izici eziyinhloko zeama-bearings aginqikayoyilezi:

1. Ukunciphisa ukungqubuzana okuncane (okuhlobene nokuslayida okungewona uketshezi), ukuqala okuguquguqukayo;

2. Ingakwazi ukuthwala imithwalo ye-radial ne-axial ngesikhathi esifanayo, yenza kube lula isakhiwo esisekelayo;

3. I-radial clearance incane, futhi imvume ingabuye iqedwe ngendlela yokulayisha ngaphambili, ngakho-ke ukunemba kokujikeleza kuphezulu;

4. Ukushintshwa okuhle nokugcinwa kulula.

 

Izici eziyinhloko zeama-bearings alulayilezi:

1. Umsebenzi ozinzile futhi akukho msindo;

2. Ukunemba okuphezulu kokujikeleza;

3. Ukulahleka okuncane kokungqubuzana ngesikhathi sokugcoba uketshezi;

4. Usayizi omncane we-radial;

5. Amandla okuthwala aphezulu.

 

Yiziphi izinzuzo kanye nokubi kwama-bearings aginqikayo uma kuqhathaniswa nama-plain bearings? Ukuhlaziywa kungokulandelayo:

 

Uma kuqhathaniswa nama-bearings angenalutho, ama-rolling bearings anezinzuzo ezilandelayo:

1. I-coefficient ye-friction yama-rolling bearings incane kunaleyo yama-bearings ashelelayo, futhi ukusebenza kahle kokudlulisela kuphezulu. Ngokuvamile, i-coefficient yokungqubuzana kwamabheringi ashelelayo ingu-0.08-0.12, kuyilapho i-coefficient yokungqubuzana kwamabheringi agingqayo ingu-0.001-0.005 kuphela;

2. Ama-rolling bearings alinganiswe, ahlanganiswa futhi ajwayelekile, alungele ukukhiqizwa nokuhlinzekwa ngobuningi, futhi kulula kakhulu ukuwasebenzisa nokuyinakekela;

3. Ama-Rolling bearings enziwe ngensimbi enensimbi futhi angaphansi kokwelashwa okushisa, ngakho-ke ama-rolling bearings awagcini nje ngokuba nezakhiwo eziphakeme zemishini nempilo ende yesevisi, kodwa futhi angasindisa izinsimbi ezingabizi kakhulu ezisetshenziswa ekwenzeni ama-sliding bearings;

4. Ukukhishwa kwangaphakathi kwe-rolling bearing kuncane kakhulu, futhi ukunemba kwemishini kwengxenye ngayinye kuphezulu, ngakho-ke ukunemba kokugijima kuphezulu. Ngesikhathi esifanayo, ukuqina kwe-bearing kungakhuliswa ngokulayisha kuqala. Lokhu kubaluleke kakhulu emishinini enembayo;

5. Amanye ama-rolling bears angakwazi ukuthwala umthwalo we-radial kanye nomthwalo we-axial ngesikhathi esifanayo, ngakho-ke ukwakheka kwe-bearing bearing kungenziwa lula;

6. Ngenxa yokusebenza kahle kokudluliselwa okuphezulu kanye nokukhiqizwa kokushisa okuphansi kwama-rolling bearings, ukusetshenziswa kwamafutha okugcoba kungancishiswa, futhi ukugcoba nokugcinwa kulula kakhulu;

7. Ama-rolling bearings angasetshenziswa kalula ku-uranium kunoma iyiphi indlela yesikhala.

 

 

Kodwa-ke, konke kuhlukaniswe kabili, futhi ama-rolling bears nawo anemibi ethile, eyinhloko yilezi:

1. Umthamo wokuthwala umthwalo wama-rolling bearings uncane kakhulu kunalowo we-sliding bearings wevolumu efanayo, ngakho-ke, ubukhulu be-radial be-rolling bearings bukhulu. Ngakho-ke, ngesikhathi sokuthwala umthwalo omkhulu kanye nesenzakalo esidinga usayizi omncane we-radial kanye nesakhiwo esihlangene (njenge-crankshaft yenjini evuthayo yangaphakathi), ama-sliding bearings asetshenziswa kakhulu;

2. Ukudlidliza nomsindo wamabheringi agingqayo kukhulu, ikakhulukazi esigabeni sakamuva sokusetshenziswa, ngakho-ke, lapho izidingo zokunemba ziphakeme kakhulu futhi ukudlidliza kungavunyelwe, ama-rolling bearings anzima ukuba abe nekhono, futhi umphumela wama-sliding bearings ngokuvamile kangcono;

3. Ama-ringing bearings azwela kakhulu ezindikimbeni zangaphandle njengama-metal chips, futhi uma izinto zangaphandle sezingenile ku-bearing, azokhiqiza ukudlidliza okukhulu nomsindo okuphakathi nendawo, okuzophinde kubangele ukulimala kwangaphambi kwesikhathi. Ngaphezu kwalokho, ama-rolling bearings nawo asengozini yokulimala kwangaphambi kwesikhathi ngenxa yokufakwa kwensimbi. Ngisho noma umonakalo wangaphambi kwesikhathi ungenzeki, kunomkhawulo wempilo yama-rolling bearings. Ngamafuphi, ama-bearings agingqayo anempilo yesevisi emfushane kunama-plain bearings.

 

Uma kuqhathaniswa nama-bearings aginqikayo kanye nama-sliding bearings, ngalinye linezinzuzo nezinkinga zalo, futhi ngalinye lithatha isenzakalo esithile esisebenzayo, ngakho-ke, lezi ezimbili azikwazi ukufaka esikhundleni somunye ngokuphelele, futhi ngayinye ithuthuka ngendlela ethile futhi yandise insimu yayo. Kodwa-ke, ngenxa yezinzuzo ezivelele zama-rolling bearings, kunokuthambekela kokuthi abafika sekwephuzile banqobe. Njengamanje, ama-rolling bearings asethuthukile aba uhlobo oluyinhloko lwemishini yokusekela, futhi asetshenziswa kabanzi.
