Nā Bearings Air Granite: Pehea lākou e hana ai a no ke aha ʻo Granite ka mea alakaʻi kūpono

Hoʻokō nā bearings ea i ka mea hiki ʻole i kahi bearing pili ke: neʻe me ka ʻole o ka ʻaʻahu, me ka ʻole o ka paheʻe ʻana a me ka ʻole o ka lubrication, ma nā pae pololei sub-micron. Akā, ʻo ka bearing ea e like me ka maikaʻi o ka ʻili e lana ai. Hōʻike kēia ʻatikala i ka physics o nā kiʻiʻoniʻoni ea, no ke aha ʻo ka granite kūlohelohe maikaʻi ka mea hoʻopili kūpono, he aha ka pololei o ka ʻili e koi ai ke ala alakaʻi, a ma hea nā pae bearing ea granite e hāʻawi ai i ka waiwai nui loa - mai nā kahua motika linear a hiki i nā ʻōnaehana nānā optical.

1. Pehea e hana ai nā bearings ea: Ke holo nei ma luna o kahi kiʻiʻoniʻoni microscopic o ka ea

Kākoʻo kahi ea ea i kāna ukana ma luna o kahi ʻili lahilahi i hoʻopaʻa ʻia, ma ke ʻano he 3-15 µm ka mānoanoa. ʻElua mau loina lako e hoʻomalu nei:

• uku hoʻēmi.Kahe ka ea ma o nā lua i ka nui kūpono i loko o kahi ʻeke pāpaʻu a i ʻole ke awāwa; hoʻoponopono ponoʻī ke kaomi i ka loli ʻana o ka hakahaka. Maʻalahi a paʻa, akā kūpono ka hiki ke ukana a ua maʻalahi ke kiʻiʻoniʻoni i nā hewa o ka ʻili kūloko.
• Pānaʻi porous.Hoʻokahe like ka ea ma o kahi mea porous (pinepine kalapona), e hana ana i kahi ʻili paʻa loa a hoʻomanawanui i ke tilt me ​​ka damping kiʻekiʻe.

ʻO kēlā me kēia ʻano, ua like ke ʻano o ka physics hoʻomalu: pili ka paʻakikī o ke kiʻiʻoniʻoni i ka huinahā o ke kaulike o ka hakahaka. Inā he waviness ka ʻili o ke alakaʻi e like me ka mānoanoa o ke kiʻiʻoniʻoni, ʻike ke kahua i ka modulation pressure - ʻike ʻia e like me ka hewa pololei, ka ʻōwili, a i ʻole ka ʻino, ka hāmare pneumatic (self-excited oscillation).ʻO ke ala alakaʻi, ʻaʻole ke bearing, e hoʻonohonoho i ka palena maikaʻi o ka ʻōnaehana.

2. No ke aha ʻo Granite ka mea alakaʻi kūpono

I kekahi manawa, nīnau nā ʻenekinia no ke aha e holo nui ai nā pae ea ma luna o ka granite ma mua o ke kila a i ʻole nā ​​alahao keramika. ʻO nā kumu he physics-material, ʻaʻole kuʻuna:

• ʻAno palaoa maikaʻi a like.Hoʻopaʻa ʻia ka granite ʻeleʻele Igneous mai kahi heheʻe hoʻokahi; ʻaʻohe hoʻokaʻawale dendritic, inclusions a i ʻole matrix palupalu e like me ka hao i hoʻolei ʻia. Hōʻike ka lapping i kahi ʻili homogeneous, no laila e noho like ka hakahaka ea ma ke kaʻina holoʻokoʻa - ʻo ia ke kumu nui loa no ke kūpaʻa o ka ʻili.
• Hoʻonui wela haʻahaʻa (≈5–8 µm/m·°C).He mau microns wale nō nā hakahaka ea; hiki i ka hapalua kekelē o ka loli o ka mahana ke hoʻoneʻe i kahi ala hao ma mua o kahi hakahaka ea. Mālama ke kūpaʻa o Granite i ke ʻano kiʻiʻoniʻoni i nā pōʻaiapuni ao-pō.
• ʻAʻohe pala, ʻaʻohe ʻaila.ʻAʻole pono ka granite ʻōlohelohe i nā uhi a ʻaʻohe lubricant - he mea koʻikoʻi ia i loko o nā lumi maʻemaʻe, kahi e hōʻole ai ka hoʻopuka ʻana i ke kinoea a me ka hana ʻana i nā ʻāpana i nā alahao i hamo ʻia.
• Ka hoʻomāmā kiʻekiʻe.Hoʻopau ka damping kūloko o Granite i ka hoʻoili haʻalulu mai ka papahele a me nā hoʻokele, e hoʻomaikaʻi ana i ke ʻano hana o ke kahua lana.
• Hiki ke hoʻopili ʻia a hiki i ka palahalaha o ka pae micron ma luna o nā mika.Hiki ke hoʻopaʻa lima ʻia nā ala granite lōʻihi a hōʻoia ʻia i kekahi mau microns ma luna o kekahi mau mika - kahi mea hiki ʻole i ka mīkini wale nō ke hoʻokō.

3. He aha ka pololei o ka ʻili e pono ai kahi alakaʻi ea?

Pili ke kikoʻī i ke ʻano o ka bearing a me ka maikaʻi o ka neʻe ʻana o ka pahuhopu, akā nā koi maʻamau no ka pololeika hali ʻana o ka ea graniteʻōnaehana:

ʻAʻole hiki ke hoʻokaʻawale ʻia ka hōʻoia mai kēia mau helu: ʻo ke ana ʻana i ka pololei ma luna o kahi alahao 2 m me ka maopopo ʻole o ka sub-micron e pono ai nā pae uila, nā autocollimators a i ʻole ka laser interferometry i loko o kahi lumi i kāohi ʻia ka mahana. ʻO ia ke kumu e koʻikoʻi ai ka hiki ke ana o ka mea hoʻolako alakaʻi e like me kā lākou mau noho lapping - wehewehe mākou i kā mākou ʻano hana i kā mākouka nānā ʻana a me ka hoʻoponopono ʻana o ka granitekaʻina hana.

4. Nā noi maʻamau

• Nā kahua motika laina.Hāʻawi nā motika linear hao ʻole i ka ikaika laumania me ke ʻano ʻole o ka cogging; i hui pū ʻia me nā alakaʻi ea granite, hiki i nā pae i ka pololei sub-micron i nā wikiwiki o 1-2 m/s - ke ʻano maʻamau no ka nānā ʻana i ka wafer a me ka nānā ʻana i ka laser.
• Nā pae kikoʻī XY.ʻO nā pae ea i hoʻomoe ʻia a planar paha ma luna o kahi kumu granite e hoʻokō i ka hana hou ʻana i ka pae nanometer no ka metrology e pili ana i ka lithography, nā kāleka probe a me ka nānā ʻana i ka hōʻike.
• Nā ʻōnaehana nānā ʻōpiko.Pono nā ʻōnaehana sensor confocal, interferometric a me chromatic i ka neʻe scan me ka ʻole o ka haʻalulu a me ke komo ʻole; ʻaʻole hoʻohui ka ʻili ʻaʻohe-hoʻopili i nā ʻāpana a ʻaʻohe hysteresis.
• Nā mea hoʻohālikelike nuipa a me nā keʻena hoʻokolohua metrology.ʻO nā kaʻa ea ma luna o nā ala granite e lawelawe i nā wahi e pono ai ka maʻemaʻe a me ka hemolele geometric.

Ma kēia mau hihia a pau, ʻelua kuleana o ka granite i ka manawa hoʻokahi: ke kumu hoʻonohonoho a me ke alakaʻi pololei. ʻO ka hoʻohui ʻana i nā mea ʻelua i hoʻokahi mea - hoʻokahi kaʻina hana lapping, hoʻokahi ʻano thermal, hoʻokahi hōʻoia - wehe i nā interfaces e hoʻokomo i ka hewa. Loaʻa nā kikoʻī noi hou aku ma kā mākounā lako semiconductornā hoʻonā.

5. Nā memo hoʻolālā ma mua o kou kuhikuhi ʻana

1. Wehewehe i ka huakaʻi, ka ukana a me ke kikowaena o ka umekaumaha— ua ana ʻia ka paʻakikī o ke kiʻiʻoniʻoni a me ka ukana mua o ke bearing a puni lākou.
2. E kuhikuhi i ka maikaʻi o ka ea— maʻamau he ea maʻemaʻe a maloʻo me ka kānana a hiki i ka 0.01 µm; ua maʻemaʻe wale ke kiʻiʻoniʻoni e like me ka lako.
3. E hoʻoholo i ka datum ana— ʻo wai ka mea nona ka kuhikuhi pololei: ka mea hana bearing, ka mea hana base, a i ʻole ka ʻōnaehana i hoʻākoakoa ʻia?
4. E hoʻolālā i ke kaiapuni— 20 ± 0.5 °C a me kahi kahua i hoʻokaʻawale ʻia e ka haʻalulu e mālama i ke ʻano i hōʻoia ʻia.
5. E noi i ka hōʻike nānā me ka ʻāpana— ana i nā waiwai pololei/palahalaha me ka ʻike ʻana o ka mea hana a me ka hiki ke hahai ʻia, ʻaʻole wale kahi leka māka.

Hopena

He hui like nā bearings ea a me ka granite: hāʻawi ka bearings i ka neʻe ʻana me ka ʻole o ka friction, a hāʻawi ka granite i ka ʻili geometrically stabil, thermally mālie, ʻaʻohe ʻāpana e hana ai i ka ʻili. Ke hana ʻia a hōʻoia ʻia nā mea ʻelua, ʻo ka hopena he ʻano neʻe ʻaʻole hiki i nā ʻōnaehana pili ke hiki.

Ke hoʻomohala nei i kahi kahua ea a i ʻole kahi kahua neʻe? E hoʻouna mai iā mākou i ka laulā huakaʻi, ka ukana, ka pololei e pono ai a me ke kaha kiʻi interface - e hana ʻenekinia a hōʻoia ʻo ZHHIMG® i nā ʻāpana alakaʻi granite no kāu ʻōnaehana, me kahi hōʻike nānā hiki ke hahai ʻia.
