Ukuqhathaniswa kwama-rolling bearings nama-plain bearings

Ukusetshenziswa kweamabheringi, izakhiwo zokungqubuzana kwama-bearings okufaka zingahlukaniswa ngama-rolling bearings nama-sliding bearings, singakhetha izinhlobo ezahlukene zama-bearings ngokuya ngezidingo ezithile zokusetshenziswa, ama-rolling bearings nama-sliding bearings anezimpawu ezahlukene zokusetshenziswa,

Izici eziyinhloko zeamabheringi ajikelezayoziyi:

1. Ukunciphisa ukungqubuzana okuncane (uma kuqhathaniswa nokuthwala okushelelayo kokungqubuzana okungeyona uketshezi), ukuqala okuguquguqukayo;

2. Ingathwala imithwalo ye-radial kanye ne-axial ngesikhathi esisodwa, okwenza kube lula ukwakheka okusekelayo;

3. Isikhala se-radial sincane, futhi isikhala singasuswa ngendlela yokulayisha kusengaphambili, ngakho-ke ukunemba kokujikeleza kuphezulu;

4. Ukushintshana okuhle kanye nokugcinwa okulula.

 

Izici eziyinhloko zeamabheringi alulaziyi:

1. Umsebenzi ozinzile futhi ongenamsindo;

2. Ukunemba okuphezulu kokujikeleza;

3. Ukulahlekelwa okuncane kokungqubuzana ngesikhathi sokugcotshwa koketshezi;

4. Usayizi omncane we-radial;

5. Umthamo ophezulu wokuthwala.

 

Yiziphi izinzuzo kanye nokungalungi kwama-rolling bearings uma kuqhathaniswa nama-plain bearings? Ukuhlaziywa kungokulandelayo:

 

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

1. I-coefficient yokungqubuzana kwama-rolling bearings incane kuneye-sliding bearings, futhi ukusebenza kahle kokudlulisela kuphezulu. Ngokuvamile, i-coefficient yokungqubuzana kwama-sliding bearings ingu-0.08-0.12, kanti i-coefficient yokungqubuzana kwama-rolling bearings ingu-0.001-0.005 kuphela;

2. Ama-rolling bearings alinganiswe, ahlelwe ngokulandelana futhi ajwayelekile, afanele ukukhiqizwa ngobuningi kanye nokuhlinzekwa, futhi kulula kakhulu ukuwasebenzisa nokunakekela;

3. Ama-rolling bearings enziwe ngensimbi yokuthwala futhi aphathwa ngokushisa, ngakho-ke ama-rolling bearings awagcini nje ngokuba nezakhiwo eziphezulu zemishini kanye nokuphila isikhathi eside, kodwa futhi angasindisa izinsimbi ezingabizi kakhulu ezisetshenziswa ekwenziweni kwama-sliding bearings;

4. Isikhala sangaphakathi sebhereyi yokugoqa sincane kakhulu, futhi ukunemba komshini wengxenye ngayinye kuphakeme, ngakho-ke ukunemba kokusebenza kuphakeme. Ngesikhathi esifanayo, ukuqina kwebhereyi kungandiswa ngokulayisha kusengaphambili. Lokhu kubaluleke kakhulu emishinini yokunemba;

5. Amanye ama-rolling bearings angathwala umthwalo we-radial kanye nomthwalo we-axial ngasikhathi sinye, ngakho-ke isakhiwo se-bearing bearing singenziwa lula;

6. Ngenxa yokusebenza kahle kokudlulisa kanye nokukhiqizwa kokushisa okuphansi kwama-rolling bearings, ukusetshenziswa kukawoyela wokugcoba kungancishiswa, futhi ukugcotshwa nokugcinwa kulula kakhulu;

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

 

 

Kodwa-ke, konke kuhlukaniswe kabili, futhi ama-rolling bearings nawo anezinkinga ezithile, eziyinhloko yilezi:

1. Umthamo wokuthwala umthwalo wama-rolling bearings mncane kakhulu kunowama-sliding bearings anomthamo ofanayo, ngakho-ke, ubukhulu be-radial bama-rolling bearings bukhulu. Ngakho-ke, uma kwenzeka umthwalo omkhulu kanye nesikhathi esidinga usayizi omncane we-radial kanye nesakhiwo esincane (njenge-crankshaft bearing yenjini yokushisa yangaphakathi), ama-sliding bearings asetshenziswa kakhulu;

2. Ukudlidliza nomsindo wama-rolling bearings kukhulu, ikakhulukazi esigabeni sokugcina sokusetshenziswa, ngakho-ke, lapho izidingo zokunemba ziphezulu kakhulu futhi ukudlidliza kungavunyelwe, ama-rolling bearings kunzima ukuwasebenzisa, futhi umphumela wama-sliding bearings ngokuvamile ungcono;

3. Ama-rolling bearings azwela kakhulu ezintweni zakwamanye amazwe njengezinsimbi zensimbi, futhi uma izinto zakwamanye amazwe zingena ku-bearings, azokhiqiza ukudlidliza okukhulu nomsindo ngezikhathi ezithile, okuzophinde kubangele umonakalo wasekuqaleni. Ngaphezu kwalokho, ama-rolling bearings nawo asengozini yomonakalo wasekuqaleni ngenxa yokufakwa kwensimbi. Ngisho noma umonakalo wasekuqaleni ungenzeki, kunomkhawulo wokuphila kwama-rolling bearings. Ngamafuphi, ama-rolling bearings anempilo yenkonzo emfushane kune-plain bearings.

 

Uma kuqhathaniswa nama-rolling bearings nama-sliding bearings, ngalinye linezinzuzo nezinkinga zalo, futhi ngalinye lithatha isikhathi esithile esifanelekile, ngakho-ke, lokhu kokubili akukwazi ukushintshana ngokuphelele, futhi ngalinye lithuthuka ngendlela ethile futhi landisa insimu yalo. Kodwa-ke, ngenxa yezinzuzo ezivelele zama-rolling bearings, kukhona ukuthambekela kokuthi ama-rolling bearings anqobe. Njengamanje, ama-rolling bearings asethuthukile aba uhlobo oluyinhloko lokusekela lwemishini, futhi asetshenziswa kabanzi.
