Ama-Bearings angenye yezingxenye zemishini ezivame ukusetshenziswa kakhulu, ezithwala ukujikeleza nokunyakaza okuphindaphindiwe kwe-shaft, ukushelela ukuhamba kwe-shaft nokusekela.Uma kusetshenziswa ama-bearings, ukungqubuzana nokuguga kungancishiswa.Ngakolunye uhlangothi, uma ikhwalithi yokuthwala iphansi, izobangela ukwehluleka komshini, ngakho-ke ukuthwala kubhekwa njengenye yezingxenye ezibalulekile zemishini.
Ngakho yiziphi izinhlobo zama-bearings akhona?
Kunezinhlobo ezimbili eziyinhloko zama-bearings: ama-sliding bearings nama-rolling bearings.
I-Sliding bearing:
Ibheyili eshelelayo ngokuvamile yakhiwa isihlalo esithwalayo kanye nesihlahla esithwalayo.Kuma-bearings ashelelayo, i-shaft ne-bearing surface kuthintana ngqo.Ingakwazi ukumelana nesivinini esikhulu kanye nokuthuthumela kwemithwalo.Ama-bearings angenalutho asetshenziswa ezinjini zezimoto, imikhumbi, nemishini.
Yifilimu yamafutha esekela ukujikeleza.Ifilimu yamafutha iyifilimu yamafutha esakazwa kancane.Lapho izinga lokushisa lamafutha likhuphuka noma umthwalo unzima kakhulu, ifilimu yamafutha izoba mncane, ibangele ukuthintana kwensimbi nokuvutha.
Eminye imisebenzi ihlanganisa:
1. Umthwalo ovumelekile mkhulu, ukudlidliza nomsindo kuncane, futhi kungagijima buthule.
2. Ngokusebenzisa isimo sokuthambisa kanye nokugcinwa, impilo yesevisi ingasetshenziswa unomphela.
I-Rolling bear
Ama-rolling bearings afakwe amabhola noma ama-roller (imigoqo eyindilinga) ukunciphisa ukumelana nokungqubuzana.Ama-rolling bearings afaka: ama-deep groove ball bearings, ama-angular contact ball bearings, tapered roller bearings, ama-thrust bearings, njll.
Eminye imisebenzi ihlanganisa:
1. Ukungqubuzana kokuqala okuphansi.
2. Uma kuqhathaniswa nama-bearings ashelelayo, kukhona ukungqubuzana okuncane.
3. Njengoba ubukhulu nokunemba kulinganiselwe, kulula ukuthenga.
Ukuqhathaniswa kwezimo zokusebenza zama-bearings amabili:
Ukuqhathaniswa kokusebenza:
Ulwazi olungeziwe: ulwazi oluyisisekelo lokuthambisa uketshezi
Ukugcotshwa kwe-Fluid kubhekisela esimweni sokuthambisa lapho okubili kuhlukaniswa ngokuphelele yifilimu ewuketshezi.Ku-shaft eshelelayo, ukucindezela okukhiqizwa uketshezi ku-aber kanye negebe le-shaft lisekela umthwalo ekuthwaleni.Lokhu kubizwa ngokuthi i-fluid film pressure.Ukugcotshwa kunciphisa ukuguga nokungqubuzana ngokunyakaza okushelelayo.Uma isetshenziswe isikhathi eside, amafutha okugcoba ayadingeka.
Ukufingqa, ama-bearings angenye yezingxenye ezisetshenziswa kakhulu (izingxenye ezijwayelekile) ekwakhiweni kwemishini.Ukusetshenziswa kahle kwama-bearings kungathuthukisa ukusebenza komkhiqizo futhi kunciphise izindleko.Ngakho-ke, kubaluleke kakhulu ukwazi kahle ulwazi olufanele lwama-bearings.
