He wehewehe kikoʻī o nā ʻano bearing i hoʻokaʻawale ʻia e nā ʻano hoʻohana
He wehewehe kikoʻī ohāpai ʻananā ʻano i hoʻokaʻawale ʻia e nā ʻano hoʻohana
Wahi a nā ʻano hana like ʻole a me nā pono hoʻohana, hiki ke hoʻokaʻawale ʻia nā bearings i nā ʻāpana penei:nā bearings wela kiʻekiʻe, nā bearings wela haʻahaʻa, nā bearings kūpaʻa i ka palaho, nā bearings kūpaʻa sulfur, nā bearings anti-magnetic, nā bearings vacuum, nā bearings lubrication ponoʻī, nā bearings seramika a me nā bearings wikiwiki.
He kūpono ia no nā noi me nā mahana hana i ʻoi aku ma mua o 120°C, a hoʻohana nui ʻia i nā ʻenekini aerojet, nā reactors atomic, nā paipu X-ray, nā lako hana semiconductor, a me nā lako hoʻoheheʻe, uhi ʻana a me ka electroplating.
2. Nā bearings mahana haʻahaʻa
Hoʻolālā ʻia no nā mahana haʻahaʻa loa ma lalo o -60°C, e like me nā pamu LNG, nā pamu naikokene/hauwai wai, nā pamu butane, nā mea hoʻoneʻe wai i loko o nā mokulele a me nā missiles. ʻO nā ʻano maʻamau he lālani hoʻokahi o nā bearings ball groove hohonu a me nā bearings cylindrical roller.
3. Nā bearings pale i ka palaho
Hoʻohana ʻia ia i nā mea hoʻohaʻahaʻa a ʻino paha, e like me ke kai, ka mahu a me nā wahi waikawa-alkali. Hana nui ʻia ia me nā mea kila kila (e like me 9Cr18 a me 9Cr18Mo), a hana pinepine ʻia ka pā hao me 0Cr19Ni9 a i ʻole ke keleawe beryllium; Hoʻohana ʻia ke kila kila kiʻekiʻe e like me Cr14Mo4 i nā wahi wela kiʻekiʻe; No nā bearings nui, hana nui ʻia nā kila kila martensitic (e like me 1Cr13 a me 2Cr13) me ka mālama ʻana i ka nitriding ʻili.
4. Nā bearings pale sulfur
No ka hydrogen sulfide (H? S) o nā wahi kinoea ʻino. He maʻalahi ka hāʻule ʻana o ke kila hali maʻamau ma muli o ka hydrogen embrittlement a i ʻole ka electrochemical corrosion, no laila pono e hoʻohana i nā bearings mea kūikawā i hana ʻia me nā alloys nickel-chromium e like me 00Cr40Ni55A13, akā ʻoi aku ka haʻahaʻa o kona paʻakikī (51 ~ 55HRC), ua kaupalena ʻia ka hiki ke hali, a pono e uku ʻia ka nānā kūikawā i ka pono o ka ʻili i ka wā e hoʻohana ai.
5. Nā bearings anti-magnetic
Hana ʻia me nā mea ʻaʻole magnetic, he haʻahaʻa loa kona permeability a kūpono no ka hoʻohana ʻana i nā wahi me nā kahua magnetic ikaika. ʻO Beryllium bronze (QBe2) kahi mea i hoʻohana pinepine ʻia me ka ikaika maikaʻi loa, elasticity, pale ʻana i ka ʻaʻahu a me ke kūpaʻa i ka corrosion, a hoʻohana nui ʻia i ka lewa, ka wai kai a me nā wahi ʻē aʻe.
6. Ka hali ʻana o ka vacuum
Hoʻohana ʻia ia i kahi kaiapuni vacuum kiʻekiʻe (ʻoi aku ke kekelē vacuum ma mua o 1.33Pa), a hoʻohana pinepine ʻia i nā lako aerospace, nā paipu X-ray, nā magnetrons a me nā noi ʻē aʻe. ʻO ke ʻano maʻamau he mau bearings ball groove hohonu a i ʻole nā bearings ball contact angular, i hana pinepine ʻia me nā mea kila kila e like me ke kila bearing GCr15 a i ʻole 9Cr18, a hoʻohana ʻia nā alloys hou e like me G60 i kekahi mau hanana vacuum kiʻekiʻe.
7. Nā bearings lubrication ponoʻī
Loaʻa iā ia kahi ʻano lubrication i kūkulu ʻia a ʻaʻole pono kahi ʻōnaehana lubrication waho. ʻO nā kūkulu maʻamau e pili ana i nā bearings pōpō hoʻopili angular hoʻokahi lālani a me nā bearings wili cylindrical pōkole radial no nā lako kahi i kaupalena ʻia ai ka lubrication a paʻakikī paha e mālama.
Hoʻololi i nā kūlana hana koʻikoʻi, e like me ka wikiwiki kiʻekiʻe, ke ana wela kiʻekiʻe, ka mahana haʻahaʻa, ka pala ikaika, ke kahua magnetic ikaika, ka vacuum a me ke kaiapuni kaomi kiʻekiʻe. He kūpono ia no nā noi kiʻekiʻe ma muli o kona hiki ke hāpai kiʻekiʻe, ke kūpaʻa wela maikaʻi loa, ka wikiwiki hope loa, ka haʻalulu haʻahaʻa, ke ola lōʻihi, ke kūpaʻa i ka pala a me ka insulation uila maikaʻi.
9. Nā bearings wikiwiki
Kūpono no nā waiwai Dm·n i ʻoi aku ma mua o 1.0 × 10 mm·r/min (ʻO Dm ke anawaena awelika o ka mea wili, ʻo n ka wikiwiki o ke apo o loko). I kēia manawa, ua ʻoi aku ka waiwai ma mua o 3.0 × 10, a hiki i ka 3.5 × 10, kahi i hoʻohana nui ʻia i nā mea hana mīkini wikiwiki, aerospace a me nā lako kikoʻī.
Ka manawa hoʻouna: Iune-03-2025
