ʻO ka ʻimi ʻana no ke ola lōʻihi, ka wikiwiki kiʻekiʻe, a me ka ʻoi aku ka maikaʻi o ka mīkini he mea pau ʻole ia. ʻOiai ke ʻano kumu o ka bearing pōpō hohonu e mau ana me ka manawa ʻole, ke hana nei kahi kipi mālie ma ka pae mea. Ke neʻe nei ka hanauna hou o kēia mau bearings ma mua o ke kila kuʻuna, e hoʻokomo ana i nā keramika ʻenekinia holomua, nā hana ʻili hou, a me nā mea i hui pū ʻia e wāwahi i nā palena hana ma mua. ʻAʻole kēia he hoʻomaikaʻi iki wale nō; he hoʻololi paradigm no nā noi koʻikoʻi.
ʻO ka piʻi ʻana o nā Bearings Hybrid a me Full-Ceramic
ʻO ka ulu nui ʻana o nā mea hana, ʻo ia ka hoʻohana ʻana i nā keramika ʻenekinia, ʻo ia hoʻi ʻo Silicon Nitride (Si3N4).
Nā Bearings Pōpō Hohonu Hybrid: Loaʻa i kēia mau mea nā apo kila i hui pū ʻia me nā pōpō silicon nitride. He mea hoʻololi nā pono:
ʻO ka Density Haʻahaʻa a me ka Hoʻemi ʻia o ka Mana Centrifugal: ʻOi aku ka māmā o nā pōpō seramika ma kahi o 40% ma mua o ke kila. I nā wikiwiki kiʻekiʻe (DN > 1 miliona), hoʻemi nui kēia i ka ukana centrifugal ma ke apo waho, e ʻae ana i ka wikiwiki hana a hiki i ka 30%.
Hoʻonui ʻia ke kūpaʻa a me ka paʻakikī: ʻO ke kūpaʻa ʻana i ka ʻaʻahu kiʻekiʻe e alakaʻi i kahi ola luhi lōʻihi i helu ʻia ma lalo o nā kūlana kūpono.
Palekana Uila: Kāohi i ka pōʻino mai ka arcing uila (fluting) i nā motika hoʻokele alapine loli (VFD), kahi ʻano hāʻule maʻamau.
Hana ma nā Mahana Kiʻekiʻe: Hiki ke hana me ka lubrication liʻiliʻi a i ʻole i nā mahana ambient kiʻekiʻe aʻe ma mua o nā bearings kila āpau.
Nā Bearings Keramika Piha: Hana ʻia me ka silicon nitride a i ʻole zirconia. Hoʻohana ʻia i nā wahi ʻino loa: hoʻokomo kemika piha, vacuum kiʻekiʻe loa kahi hiki ʻole ke hoʻohana ʻia nā lubricants, a i ʻole i nā mīkini magnetic resonance imaging (MRI) kahi e pono ai ka non-magnetism piha.
ʻEnekinia ʻIli Kiʻekiʻe: Ka Mana o kekahi mau Microns
I kekahi manawa, ʻo ka hoʻonui ikaika loa he papa microscopic ma luna o ka ʻili o kahi bearings kila maʻamau.
ʻO nā uhi kalapona Diamond-Like (DLC): He uhi paʻakikī loa, laumania loa, a haʻahaʻa hoʻi i hoʻopili ʻia i nā ala holo a me nā pōpō. Hoʻemi nui ia i ka ʻaʻahu pipili i ka wā hoʻomaka (lubrication palena) a hāʻawi i kahi pale e kūʻē i ka pala, e hoʻolōʻihi nui ana i ke ola lawelawe i nā kūlana lubrication maikaʻi ʻole.
Nā Uhi Hoʻokahe Kohu Kino (PVD): Hoʻonui nā uhi Titanium Nitride (TiN) a i ʻole Chromium Nitride (CrN) i ka paʻakikī o ka ʻili a hōʻemi i ka friction, kūpono no nā noi me ka paheʻe kiʻekiʻe a i ʻole ka lubrication marginal.
ʻAno Laser: Ke hoʻohana nei i nā lasers e hana i nā lua liʻiliʻi a i ʻole nā kahawai ma ka ʻili o ke ala holo. Hana kēia mau mea ma ke ʻano he mau waihona liʻiliʻi no ka lubricant, e hōʻoiaʻiʻo ana i kahi kiʻiʻoniʻoni e kū mau ana, a hiki ke hōʻemi i ka friction a me ka mahana hana.
Nā Hana Hou i ka ʻenehana Polymer a me Composite
Nā Hale Paʻa Polymer o ka Hanauna Hou: Ma waho aʻe o ka polyamide maʻamau, hāʻawi nā mea hou e like me Polyether Ether Ketone (PEEK) a me Polyimide i ke kūpaʻa wela kūikawā (hana mau > 250°C), ke kūpaʻa kemika, a me ka ikaika, e hiki ai i nā hale paʻa māmā a mālie no nā noi hana koʻikoʻi.
Nā Huihui i Hoʻoikaika ʻia e ka Fiber: Ke hoʻomau nei ka noiʻi ʻana i nā apo i hana ʻia mai nā polymers i hoʻoikaika ʻia e ke kalapona (CFRP) no nā noi māmā loa e like me nā spindles aerospace a i ʻole nā turbochargers miniature, kahi e koʻikoʻi ai ka hoʻemi ʻana i ke kaumaha.
Ka Pilikia Hoʻohuihui a me ka Nānā i ka Wā e Hiki Mai Ana
ʻAʻole nele ka hoʻohana ʻana i kēia mau mea holomua i nā pilikia. Pono pinepine lākou i nā lula hoʻolālā hou (nā coefficients hoʻonui wela like ʻole, nā moduli elastic), nā kaʻina hana mīkini kūikawā, a hele mai i kahi kumukūʻai mua kiʻekiʻe. Eia nō naʻe, ʻaʻole hiki ke lanakila ʻia kā lākou Total Cost of Ownership (TCO) i ka hoʻohana kūpono.
Hopena: Ke ʻenekinia ʻana i ka palena o ka mea hiki
ʻAʻole wale ka wā e hiki mai ana o ka bearing pōpō hohonu e pili ana i ka hoʻomaʻemaʻe ʻana i ke kila. E pili ana i ka hoʻohui akamai ʻana i ka ʻepekema mea me ka hoʻolālā mīkini maʻamau. Ma ka hoʻolaha ʻana i nā bearing seramika hybrid, nā ʻāpana i uhi ʻia me ka DLC, a i ʻole nā pahu polymer holomua, hiki i nā ʻenekinia ke kuhikuhi i kahi bearing pōpō hohonu e hana wikiwiki ana, lōʻihi, a ma nā wahi i manaʻo ʻia he pāpā. Hōʻoia kēia hoʻomohala alakaʻi mea e hoʻomau kēia ʻāpana kumu i ka hoʻokō a me ka hoʻokele ʻana i nā koi o nā mīkini holomua loa o ka lā ʻapōpō, mai nā mokulele uila āpau a hiki i nā mea hana ʻeli hohonu. Ua hiki mai ka wā o ka bearing "mea akamai".
