Amabheringi okushisa okuphezulu

Kuyini i-High Temperature Bearing?

Lokhu okubizwa ngokuthi i-bearing yokushisa okuphezulu kubhekisela ekutheni izinga lokushisa lokusebenza liphakeme kunezinga lokushisa le-bearing evamile, kanye ne-bearing esetshenziswa ekushiseni okujwayelekile kokusebenza okungaphezu kuka-150 degrees.° ibizwa ngokuthi i-bearing enokushisa okuphezulu.

 

Izici zama-bearings okushisa okuphezulu:

 

1. Ukuthambisa impilo yonke, akukho grisi engezwayo ngesikhathi sokusetshenziswa.

 

2. Isebenza kahle, ikhwalithi iphakeme kaningi kuneye-bearings evamile.

 

3. Izuze ukwethenjwa ngamakhasimende ethu ngempilo yesevisi ende.

 

4. Ama-bearings anokushisa okuphezulu asetshenziswa kabanzi ekusetshenzisweni kwensimbi, kuma-oven, engilazini, kuma-oven okuqhuma, emishinini yokupenda kanye neminye imishini ngaphansi kwemisebenzi yokushisa okuphezulu.

 

Ama-bearings okushisa okuphezulu asetshenziswa kakhulu ezinjinini zezindiza, kuma-turbine egesi, ezinhlelweni ze-nuclear reactor, kuma-disc e-tungsten e-X-ray tube, ezimotweni zesivinini esikhulu, amarokhethi, kanye nasemkhathini.

 

Ukufakwa kwama-bearings okushisa okuphezulu

Ngaphezu kwalokho, uma ingcindezi ifakwa ohlangothini olulodwa lwendandatho (njengendandatho yangaphandle), kanti olunye uhlangothi lwendandatho (njengendandatho yangaphakathi) lucindezelwa kulo ngesici sokugoqa, lokhu kuvame ukubangela ukugoba noma ukuklwebheka ebusweni bokugoqa, futhi akumelwe kusetshenziswe, ikakhulukazi uma ibhere elingahlukaniseki lifakwe kushaft kanye nendlu yokuthwala ngesikhathi esisodwa.

 

Enkambisweni yokushisa nokufaka i-bearing, kubalulekile ukuqonda ububanzi bokushisa be-bearing yokushisa okuphezulu ngaphansi kwama-bearing ahlukahlukene okushisa okuphezulu.

 

Ukufaneleka kweamabheringi okushisa okuphezulu

1. Ukuphazamiseka

 

Indandatho yangaphakathi nendandatho yangaphandle yento egoqayo inamathele kushaft noma ebhokisini lokuthwala, futhi uma ilayishwa, indandatho kanye neshaft noma ibhokisi lokuthwala azinazo izinyakazo ezihlobene ze-radial, axial kanye ne-rotational, futhi lokhu kunyakaza okuhlobene kuzobangela ukungqubuzana, ukungqubuzana ukugqwala noma imifantu yokungqubuzana ebusweni bokuhlangana, ukuze kubangele umonakalo kubhereyi, ushaft kanye nebhokisi lokuthwala, bese kuba yimpuphu yokukhuhla exutshwe kubhereyi, okuba yimbangela yokusebenza kabi, ukushisa okungavamile noma ukudlidliza.

 

Ngokuphathelene nendlela yokuthwala engaguquki, kungcono ukushiya inani lokuphazamiseka ebusweni bokuhlangana kwendandatho kanye nomgodi noma indlu yokuthwala, futhi ukulingana okungaguquki kube kuhle kakhulu, ukuze umthwalo wendandatho enodonga oluncane usatshalaliswe ngokulinganayo endaweni ezungezile ngaphandle kokuthinta umthamo womthwalo webheringi.

 

Kodwa-ke, ngaphezu kokuphazamiseka kokuhlanganisa nokwehlisa i-bearing, ayikwazi ukusetshenziswa kuzo zonke izimo lapho i-bearing ihlukanisiwe futhi ayikwazi ukushukunyiswa nge-axial lapho i-bearing ihlukanisiwe lapho kusetshenziswa i-bearing.

 

2. Ukukhetha okufanele

 

Ukukhetha ukulingana ngokuvamile kwenziwa ngokwemigomo elandelayo:

 

(1) Ngokuya ngesiqondiso kanye nohlobo lomthwalo osebenza kubheriya nokuthi yiliphi uhlangothi lwezindandatho zangaphakathi nezangaphandle ezijikelezayo, umthwalo othwalwa yindandatho ngayinye ungahlukaniswa ngomthwalo ojikelezayo, umthwalo omile, noma umthwalo ongaqondile, indandatho ethwala umthwalo ojikelezayo kanye nomthwalo ongaqondile kufanele ithathe ukulingana okungaguquki (ukulingana kokuphazamiseka), indandatho ethwala umthwalo ongaqondile ingathatha ukulingana kokuguquka noma ukulingana okuguquguqukayo (ukulingana kokuvula), lapho umthwalo wokuthwala umkhulu noma uthwala ukudlidliza kanye nomthwalo wokushaqeka, ukuphazamiseka kumele kwandiswe, lapho kusetshenziswa i-hollow shaft, ibhokisi lokuthwala elinodonga oluncane noma i-alloy elula kanye nebhokisi lokuthwala lepulasitiki, Kubalulekile futhi ukwandisa inani lokuphazamiseka.

 

(2) Uma kudingeka ukuze kugcinwe ukunemba okuphezulu kokujikeleza, kufanele kusetshenziswe amabheringi anokunemba okuphezulu, futhi ukunemba kobukhulu be-shafts namabhokisi okuthwala kumele kuthuthukiswe, ukuze kugwenywe ukuphazamiseka okukhulu, uma ukuphazamiseka kukhulu kakhulu, ukunemba kwejiyometri yebhokisi lebhereyi noma le-axle kungathinta ijiyometri yendandatho yokuthwala, ngaleyo ndlela kulimaze ukunemba kokujikeleza kwebhereyi, uma izindandatho zangaphakathi nezangaphandle zamabheringi angahlukanisi (njenge-deep groove ball bearing) zilingana kahle, khona-ke ukufakwa kwebheringi nokuhlukaniswa kwayo akulungile kakhulu, futhi kungcono ukusebenzisa ukulingana okuguquguqukayo kolunye uhlangothi lwendandatho yangaphandle.

 

3. Kunconywa ukusebenzisana

 

Ngokuphathelene nobubanzi bomgodi kanye nokubekezelelana kosayizi webhore webhore kanye nendlu yokuthwala lapho kufakwe khona amabheringi, i-ISO283 (ukubekezelelana kobukhulu kanye nokufanelana) isetshenziswe ochungechungeni lwe-metric, ngakho-ke ukubekezelelana kokufaneleka kunqunywe ngokuya ngobubanzi bomgodi kanye nokubekezelelana kosayizi webhore okukhethiwe.
