Incazelo eningiliziwe yeibhereizinhlobo ezihlukaniswe ngezimpawu zokusebenzisa

Ngokuya ngezimo zokusebenza ezahlukene kanye nezidingo zokusetshenziswa, ama-bearings angahlukaniswa ngezigaba ezilandelayo:amabheringi okushisa okuphezulu, amabheringi okushisa okuphansi, amabheringi amelana nokugqwala, amabheringi amelana nesibabule, amabheringi alwa nemagnethi, amabheringi e-vacuum, amabheringi azigcobayo, amabheringi e-ceramic kanye namabheringi ashesha kakhulu.

 

1.Amabheringi okushisa okuphezulu

Ifanele ukusetshenziswa lapho amazinga okushisa okusebenza edlula u-120°C, futhi isetshenziswa kabanzi ezinjinini ze-aerojet, kuma-reactor e-athomu, kumashubhu e-X-ray, emishinini yokukhiqiza ye-semiconductor, kanye nasemishinini yokuncibilikisa, yokumboza kanye neyokufaka i-electroplating.

 

2. Amabheringi okushisa aphansi

Yakhelwe amazinga okushisa aphansi kakhulu angaphansi kuka--60°C, njengephampu ze-LNG, amaphampu e-nitrogen/hydrogen aketshezi, amaphampu e-butane, amadivayisi okuqhubekela phambili koketshezi emkhathini nasezicibini. Izakhiwo ezivamile ama-single row deep groove ball bearing kanye nama-cylindrical roller bearing.

 

3. Amabheringi amelana nokugqwala

Isetshenziswa ezindaweni ezinomswakama noma ezigqwalisayo, njengamanzi olwandle, umusi kanye nezindawo ezine-acid-alkali. Yenziwe kakhulu ngezinto zensimbi engagqwali (njenge-9Cr18 kanye ne-9Cr18Mo), futhi ikheji livame ukwenziwa nge-0Cr19Ni9 noma ithusi le-beryllium; Insimbi engagqwali enokushisa okuphezulu njenge-Cr14Mo4 isetshenziswa ezindaweni ezinokushisa okuphezulu; Kuma-bearings amakhulu, izinsimbi ezingagqwali ze-martensitic (njenge-1Cr13 kanye ne-2Cr13) zenziwe kakhulu ngokwelashwa kwe-surface nitriding.

 

4. Amabheringi amelana nesibabule

Kwi-hydrogen sulfide (H? S) yezindawo zegesi ezinzima. Insimbi ejwayelekile yokuthwala kulula ukuyiqeda ngenxa yokuqhekeka kwe-hydrogen noma ukugqwala kwe-electrochemical, ngakho-ke kuyadingeka ukusebenzisa ama-bearings akhethekile enziwe ngama-alloys e-nickel-chromium njenge-00Cr40Ni55A13, kodwa ubulukhuni bayo (51~55HRC) buphansi kancane, amandla okuthwala alinganiselwe, futhi ukunaka okukhethekile kudingeka kukhokhwe ekuqineni kobuso lapho kusetshenziswa.

 

5. Amabheringi alwa nomagnetic

Yenziwe ngezinto ezingezona ezikagesi, inomoya omncane kakhulu futhi ifanele ukusetshenziswa ezindaweni ezinamasimu anamandla kazibuthe. I-Beryllium bronze (QBe2) iyinto esetshenziswa kakhulu enamandla amahle kakhulu, ukunwebeka, ukumelana nokuguguleka kanye nokumelana nokugqwala, futhi isetshenziswa kabanzi emoyeni, emanzini olwandle nakwezinye izindawo.

 

6. Ukuthwala i-vacuum

Isetshenziswa endaweni ene-vacuum ephezulu (izinga le-vacuum eliphakeme kune-1.33Pa), futhi ivame ukusetshenziswa emishinini yezindiza, amashubhu e-X-ray, ama-magnetron nakwezinye izinhlelo zokusebenza. Isakhiwo esijwayelekile ama-deep groove ball bearing noma ama-angular contact ball bearing, avame ukwenziwa ngezinto zensimbi engagqwali njengensimbi ye-GCr15 bearing noma i-9Cr18, kanti ama-alloy amasha njenge-G60 asetshenziswa kwezinye izikhathi ze-vacuum ezinengcindezi ephezulu.

 

7. Amabheringi azigcobayo

Inendlela yokugcoba eyakhelwe ngaphakathi futhi ayidingi uhlelo lokugcoba lwangaphandle. Ukwakhiwa okujwayelekile kufaka phakathi ama-single row angular contact ball bearing kanye nama-radial short cylindrical roller bearing emishini lapho ukugcoba kulinganiselwe noma kunzima ukukugcina.

 

8. Amabheringi e-Ceramic

Zivumelanise nezimo zokusebenza ezimbi kakhulu, njengesivinini esiphezulu, izinga lokushisa eliphezulu, izinga lokushisa eliphansi, ukugqwala okunamandla, insimu enamandla kazibuthe, i-vacuum kanye nendawo enomfutho ophezulu. Ilungele ukusetshenziswa okuphezulu ngenxa yomthamo wayo wokuthwala ophezulu, ukumelana nokushisa okuhle kakhulu, isivinini esiphezulu esiphezulu, ukungqubuzana okuphansi, impilo ende, ukumelana nokugqwala kanye nokufakwa kahle kukagesi.

 

9. Amabheringi asheshayo

Ifanele amanani e-Dm·n adlula u-1.0×10 mm·r/min (i-Dm ububanzi obumaphakathi bento egingqikayo, i-n ijubane lendandatho yangaphakathi). Njengamanje, inani selidlule u-3.0×10, futhi lafinyelela ngisho no-3.5×10, okusetshenziswa kabanzi kumathuluzi omshini asheshayo, imishini yezindiza kanye nokunemba.
