Loaʻa nā mea hoʻopalapala ʻōwili i nā mea no ka ʻōwili ʻana i nā ʻāpana a me nā hīnaʻi, rivets a me nā mea kōkua ʻē aʻe.

ʻO nā bearings rolling a me kā lākou mau ʻāpana i hana ʻia i ke kila.ʻO nā kila wili kaʻa maʻamau he kila chromium kiʻekiʻe a me ke kila carburized.Me ka hoʻomohala ʻana o ka ʻepekema a me ka ʻenehana hou a me ka hoʻonui ʻana i ka hoʻohana ʻana i nā bearings rolling, ke piʻi aʻe nei nā koi no nā bearings, e like me ke kiʻekiʻe kiʻekiʻe, ke ola lōʻihi a me ka hilinaʻi kiʻekiʻe.No kekahi mau bearings kūikawā, pono e loaʻa nā waiwai o ke kūpaʻa wela kiʻekiʻe, ka pale ʻana i ka corrosion, non-magnetic, ultra-low temperature, a me ka pale radiation.Eia kekahi, hoʻokomo pū nā mea halihali i nā mea hao, nā metala non-ferrous a me nā mea non-metallic.Eia kekahi, hoʻohana ʻia nā bearings i nā mea seramika i nā locomotives, nā kaʻa, nā subways, aviation, aerospace, chemical and other fields.

ʻO nā koi kumu o ka rolling bearings no nā mea e hilinaʻi nui i ka hana hana o ka bearing.Inā kūpono ke koho ʻana i nā mea no nā bearings rolling e loaʻa ka hopena nui i kāna hana a me ke ola.Ma keʻano laulā, ʻo nā ʻano hemahema nui o nā bearings ʻo ka luhi ʻana ma lalo o ka hana o ke koʻikoʻi hoʻololi, a me ka nalowale o ka pololei o ka lawe ʻana ma muli o ka friction a me ka ʻaʻahu.Eia kekahi, aia nā māwae, indentations, rust a me nā kumu ʻē aʻe e hōʻino ai i ka bearing.No laila, pono ke kū'ē kiʻekiʻe o nā bearings i ka plastic deformation, ka liʻiliʻi o ka friction a me ka ʻaʻahu, ka pololei o ka rotation maikaʻi, ka pololei a me ka paʻa, a me ke ola luhi lōʻihi.A ʻo ka nui o nā waiwai i hoʻoholo ʻia e nā mea hana a me nā kaʻina hana wela.

No ka mea ua hoʻoholo ʻia nā koi kumu no nā mea o ka rolling bearings e ke ʻano o ka pōʻino o nā bearings, pono nā mea e pono ai e hana i nā bearings rolling i kēia mau waiwai ma hope o ka mālama ʻana i ka wela i ke kaʻina hana aʻe:

a High contact fatigue ikaika

ʻO ka hoʻopili ʻana i ka luhi luhi ke ʻano nui o ka hāʻule maʻamau.I ka wā e hana ai ka ʻōwili ʻana, ʻo nā mea ʻōwili ma waena o nā raceways o nā apo o loko a me waho o ka bearing, a ʻo ka ʻāpana pili e halihali i nā ukana hoʻololi manawa, hiki ke hiki i nā haneli haneli mau manawa i kēlā me kēia minuke.Ma lalo o ka hana mau ʻana o ke koʻikoʻi hoʻololi i kēlā me kēia manawa, ʻike ʻia ka ʻili pili i ka ʻili ʻana i ka luhi.I ka hoʻomaka ʻana o ka ʻōwili ʻana i ka ʻili, e hoʻonui ʻia ka haʻalulu a me ka walaʻau, a piʻi nui ka mahana hana, e pōʻino ai ka bearing.Kapa ʻia kēia ʻano pōʻino i ka pōʻino luhi pili.No laila, pono ke kila no nā bearings e loaʻa i ka ikaika luhi hoʻopili kiʻekiʻe.

b Kiʻekiʻe abrasion kū'ē

Ke hana maʻamau ka ʻōwili ʻana, ma waho aʻe o ke kuʻekuʻe kaʻa, ua hui pū ʻia me ka friction sliding.ʻO nā ʻāpana nui o ka friction sliding: ʻo ka ʻili pili ma waena o ka mea ʻōwili a me ke ala heihei, ka ʻili pili ma waena o ka mea ʻōwili a me ka ʻeke pahu, ma waena o ka hale a me ka ʻaoʻao alakaʻi apo, a me ka ʻaoʻao hope o ka roller a me ke alakaʻi apo E kali. ma waena o nā paia ʻaoʻao.ʻO ka loaʻa ʻana o ke kuʻekuʻe paheʻe i loko o nā bearings ʻolokaʻa ʻo ia ka mea e hoʻopau ai i nā ʻāpana amo.Inā maikaʻi ʻole ka pale ʻana o ke kila bearing, e nalowale ka ʻōwili ʻana i kona pololei ma mua o ka ʻaʻahu ʻana a i ʻole ka emi ʻana o ka pololei o ka rotation, e hoʻonui ai i ka haʻalulu o ka bearing a hoʻemi i kona ola.No laila, koi ʻia ka mea kila e loaʻa ai ke kūpaʻa kiʻekiʻe.

c palena elastic kiʻekiʻe

I ka wā e hana ana ka ʻōwili ʻana, no ka mea liʻiliʻi ka wahi hoʻopili ma waena o ka mea ʻōwili a me ka raceway o ke apo, ʻoi aku ka nui o ke kaomi hoʻopili ʻana o ka ʻili pili i ka wā e kau ʻia ai ka bearing, ʻoi aku ma lalo o ke kūlana o ka ukana nui.I mea e pale aku ai i ka nui o ka plastic deformation ma lalo o ke koʻikoʻi hoʻopili kiʻekiʻe, ka nalowale o ka pololei o ka lawe ʻana a i ʻole ka ʻili o ka ʻili, pono e loaʻa kahi palena elastic kiʻekiʻe.

d Ka paakiki kupono

ʻO ka paʻakikī kekahi o nā hōʻailona koʻikoʻi o nā bearings rolling.He pili pili loa ia me ka ikaika o ka luhi, ka pale ʻana, a me ka palena elastic, a pili pono i ke ola o nā bearings rolling.Hoʻoholo pinepine ʻia ka paʻakikī o ka bearing e ke kūlana holoʻokoʻa o ke ʻano haʻahaʻa a me ka nui, ka nui a me ka mānoanoa o ka pā.Pono e kūpono ka paʻakikī o ke kila wili, nui a liʻiliʻi paha e hoʻopili i ke ola lawelawe o ka bearing.E like me kā mākou e ʻike ai, ʻo nā ʻano hemahema nui o nā bearings e pili ana i ka luhi luhi a me ka nalo ʻana o ka pololei o ka lawe ʻana ma muli o ke kūpaʻa maikaʻi ʻole o ka ʻaʻahu a i ʻole ke ʻano instability;inā ʻaʻohe ʻano o ka paʻakikī o nā ʻāpana amo, e hoʻokumu ʻia lākou e ka haki ʻana i ka wā i hoʻokau ʻia i nā ukana hopena nui.ʻO ka luku ʻana i ka bearing.No laila, pono e hoʻoholo ʻia ka paʻakikī o ka bearing e like me ke kūlana kikoʻī o ka halihali a me ke ala o ka pōʻino.No ka nalo ʻana o ka pololei o ka lawe ʻana ma muli o ka luhi ʻana a i ʻole ka pale ʻana i ka ʻaʻahu, pono ke koho ʻia ka ʻoi aku ka paʻakikī no ka lawe ʻana i nā ʻāpana;no nā bearings e pili ana i nā ukana hopena nui (e like me nā wili wili: nā bearings, nā alahao kaʻaahi a me kekahi mau bearings automotive, etc.), pono lākou e hoʻemi kūpono Pono pono ka paʻakikī no ka hoʻomaikaʻi ʻana i ka paʻakikī.

e kekahi hopena oolea

Nui nā bearings rolling e hoʻokau ʻia i kahi haʻahaʻa hopena i ka wā o ka hoʻohana ʻana, no laila e koi ʻia ke kila bearing e loaʻa kahi pae o ka paʻakikī e hōʻoia i ka pōʻino ʻole o ka bearing ma muli o ka hopena.No nā bearings e kū'ē i nā ukana hopena nui, e like me nā bearings rolling mill, bearings railway, etc., pono nā mea e loaʻa ai ka paʻakikī hopena kiʻekiʻe a me ka paʻakikī haʻihaʻi.Kekahi o keia mau bearings hoʻohana bainite quenching wela kaʻina lapaʻau, a me kekahi hoʻohana carburized mea kila.E hōʻoia i kēia mau bearings i ʻoi aku ka maikaʻi o ka hopena a me ka paʻakikī.

f Ke kūpaʻa maikaʻi

ʻO nā bearings ʻo ia nā ʻāpana mechanical precision, a ua helu ʻia ko lākou pololei i nā micrometers.I ke kaʻina o ka mālama ʻana a me ka hoʻohana lōʻihi, hoʻololi i ka hui kūloko a i ʻole nā ​​hoʻololi ʻana i ke koʻikoʻi e hoʻololi i ka nui o ka bearing e hoʻololi i ka pololei o ka bearing.No laila, i mea e hōʻoiaʻiʻo ai i ka pololei o ka nui o ka bearing, pono ke kūpaʻa maikaʻi o ka mea hao.

g Hana maikaʻi i ka anti-rust

He nui nā kaʻina hana a me ka pōʻai hana lōʻihi.Pono e mālama ʻia kekahi mau ʻāpana semi-hoʻopau a hoʻopau ʻia no ka manawa lōʻihi ma mua o ka hui ʻana.No laila, ʻoi aku ka maikaʻi o ka lawe ʻana i nā ʻāpana i kahi degere o ka corrosion i ka wā o ka hana ʻana a i ʻole ka mālama ʻana i nā huahana i hoʻopau ʻia.Aia i loko o ka ea haʻahaʻa.No laila, koi ʻia ka mea kila e loaʻa ai ke kūpaʻa maikaʻi.

h Hana maikaʻi ke kaʻina hana

I ke kaʻina hana o ka rolling bearings, pono kāna mau ʻāpana i nā kaʻina hana anuanu a wela.Pono kēia e loaʻa i ke kila bearing nā waiwai kaʻina hana maikaʻi, e like me ke anuanu a me ka wela, ka ʻoki ʻana, ka hana wili a me ka hana wela wela, etc. .

Eia kekahi, no nā bearings i hoʻohanaʻia ma lalo o nā kūlana hana kūikawā, ma waho aʻe o nā koi kumu i'ōleloʻia ma luna nei, pono e hoʻokomo i nā koi kūikawā kūikawā kūpono no ke kila i hoʻohanaʻia, e like me ke kiʻekiʻe o ka mahana wela, ka wikiwiki wikiwiki, ka paleʻana i ka corrosion a me ka hana antimagnetic.
