Kufotokozera mwatsatanetsatane mitundu ya zonyamula zomwe zimagawidwa malinga ndi momwe zimagwiritsidwira ntchito
Kufotokozera mwatsatanetsatane kwachogwiriramitundu yogawidwa malinga ndi makhalidwe ogwiritsira ntchito
Malinga ndi malo osiyanasiyana ogwirira ntchito ndi zosowa zogwiritsira ntchito, ma bearing akhoza kugawidwa m'magulu otsatirawa:ma bearing otentha kwambiri, ma bearing otsika kutentha, ma bearing osagwira dzimbiri, ma bearing osagwira sulfure, ma bearing otsutsana ndi maginito, ma bearing a vacuum, ma bearing odzipaka okha, ma bearing a ceramic ndi ma bearing othamanga kwambiri.
Ndi yoyenera kugwiritsidwa ntchito ndi kutentha kopitilira 120°C, ndipo imagwiritsidwa ntchito kwambiri mu injini za aerojet, ma atomu reactors, ma X-ray tubes, zida zopangira ma semiconductor, komanso zida zosungunulira, zokutira ndi zopangira ma electroplating.
Yopangidwira kutentha kotsika kwambiri pansi pa -60°C, monga mapampu a LNG, mapampu a nayitrogeni/hydrogen amadzimadzi, mapampu a butane, zida zoyendetsera madzi mumlengalenga ndi ma roketi. Kapangidwe kofala ndi ma bearing a mpira wa mzere umodzi wozama ndi ma bearing a cylindrical roller.
3. Mabearing osagwira dzimbiri
Amagwiritsidwa ntchito m'malo onyowa kapena owononga, monga madzi a m'nyanja, nthunzi ndi malo okhala ndi asidi. Amapangidwa makamaka ndi zitsulo zosapanga dzimbiri (monga 9Cr18 ndi 9Cr18Mo), ndipo khola nthawi zambiri limapangidwa ndi 0Cr19Ni9 kapena beryllium bronze; Chitsulo chosapanga dzimbiri chotentha kwambiri monga Cr14Mo4 chimagwiritsidwa ntchito m'malo otentha kwambiri; Pa ma bearing akuluakulu, zitsulo zosapanga dzimbiri za martensitic (monga 1Cr13 ndi 2Cr13) zimapangidwa makamaka ndi mankhwala oyeretsera pamwamba.
4. Mabearing osagonjetsedwa ndi sulfure
Pa hydrogen sulfide (H? S) ya mpweya wovuta. Chitsulo chonyamula katundu wamba chimalephera mosavuta chifukwa cha kuphulika kwa hydrogen kapena electrochemical corrosion, kotero ndikofunikira kugwiritsa ntchito ma bearing apadera opangidwa ndi nickel-chromium alloys monga 00Cr40Ni55A13, koma kuuma kwake (51~55HRC) ndikochepa pang'ono, mphamvu yonyamula katundu ndi yochepa, ndipo chisamaliro chapadera chiyenera kuperekedwa ku umphumphu wa pamwamba pa chinthucho mukachigwiritsa ntchito.
5. Mabeya otsutsana ndi maginito
Yopangidwa ndi zinthu zopanda maginito, imakhala ndi mpweya wochepa kwambiri ndipo ndi yoyenera kugwiritsidwa ntchito m'malo okhala ndi mphamvu zamaginito zamphamvu. Beryllium bronze (QBe2) ndi chinthu chomwe chimagwiritsidwa ntchito kwambiri chomwe chili ndi mphamvu zabwino kwambiri, kusinthasintha, kukana kuvala komanso kukana dzimbiri, ndipo chimagwiritsidwa ntchito kwambiri mumlengalenga, m'madzi a m'nyanja ndi m'malo ena.
6. Kunyamula vacuum
Amagwiritsidwa ntchito pamalo odzaza vacuum (vacuum digiri yoposa 1.33Pa), ndipo amagwiritsidwa ntchito kwambiri mu zida zamlengalenga, machubu a X-ray, ma magnetron ndi ntchito zina. Kapangidwe kake kamakhala ma bearing a mpira wozama kapena ma bearing a angular contact ball, omwe nthawi zambiri amapangidwa ndi zipangizo zosapanga dzimbiri monga GCr15 bearing steel kapena 9Cr18, ndipo ma alloys atsopano monga G60 amagwiritsidwa ntchito nthawi zina zodzaza vacuum.
7. Mabearing odzipaka okha
Ili ndi njira yopangira mafuta odzola yomwe imamangidwa mkati mwake ndipo siifuna njira yopangira mafuta odzola yakunja. Kapangidwe kake kamakhala ndi ma bearing a mpira wolumikizana ndi mzere umodzi ndi ma bearing afupiafupi a cylindrical roller a zida zomwe mafuta odzola amakhala ochepa kapena ovuta kusamalira.
Sinthani malinga ndi momwe zinthu zilili pa ntchito, monga liwiro lalikulu, kutentha kwambiri, kutentha kochepa, dzimbiri lamphamvu, mphamvu yamphamvu yamaginito, vacuum ndi malo opanikizika kwambiri. Ndi yabwino kwambiri chifukwa cha mphamvu yake yonyamula katundu, kukana kutentha kwambiri, liwiro lalikulu, kukangana kochepa, kukhala nthawi yayitali, kukana dzimbiri komanso kutchinjiriza bwino magetsi.
9. Maberiyani othamanga kwambiri
Yoyenera kugwiritsa ntchito Dm·n yoposa 1.0×10 mm·r/min (Dm ndi m'mimba mwake wapakati wa chinthu chozungulira, n ndi liwiro la mphete yamkati). Pakadali pano, mtengo wake wapitirira 3.0×10, ndipo wafika ngakhale 3.5×10, yomwe imagwiritsidwa ntchito kwambiri mu zida zamakina zothamanga kwambiri, ndege komanso zida zolondola.
