I ka hana ʻana o Precision Bearings, no ke aha e pono ai ka mīkini honing, he aha kāna mau hana, a pehea ke ʻano o ka hana honing?

1. No ke aha e pono ai ka mīkini honi i ka hana ʻana i ka lawe pololei ʻana

Pono ka Honing no ka meaKe koi nei nā bearings i ka pololei kiʻekiʻe kiʻekiʻe, ka poepoe, ka cylindricity, a me ka pau ʻana o ka ʻilii nā mea e like menā apo o loko, nā apo o waho, a me nā lima lima. ʻAʻole hiki i ka wili wale ʻana ke hoʻokō pono i kēia mau koi pololei ma muli o ke koena o ke koʻikoʻi o ka ʻili, ka micro{1}}ʻeleʻele, a me ka hoʻowaliwali o ke ʻano.

Nā kumu nui:

Loaʻa i ka Ultra -Kōleʻa Kiʻekiʻe

Pono nā bearings i ka hoʻomanawanui i kamicron a i ʻole sub{0}}micron range ( I lalo a i ʻole like me 1–2 μm).

Hoʻopau ʻo Honing i nā micrometers hope loa o nā mea e hoʻokō ai i kēia mau ʻae ʻana ma hope o ka wili ʻana a i ʻole ka mālama wela.

Hoʻomaikaʻi i ka hoʻopau ʻana i ka ʻili

Pono nā ala heihei a me nā lua e hoʻopau i ka laulā oRa 0.02–0.2 μm.

Hoʻopau ʻo Honing i nā kaha wili a hana i kahi pāpū -like me ka ʻili no ka lubrication maikaʻi a me ka hoʻemi ʻana i ka friction.

Hoʻoponopono i nā hewa Geometric

Hoʻoponopono i nā hemahema liʻiliʻi e like mema waho o-o-poepoe, li'ili'i, a me ka naluma muli o nā kaʻina hana mua.

E hōʻoia i nā ala heihei a me nā lua he cylindrical a me ka coaxial.

Hoʻonui i ka pale ʻana a me ke ola ʻana

Mālama ka ʻili i hoʻomaʻemaʻe ʻia i nā kiʻiʻoniʻoni lubricant ʻoi aku ka maikaʻi, e hōʻemi ana i ka metala-i-pili metala.

Hoʻemi i ka wela frictional a hoʻomaikaʻi i ke ola hana.

2. Nā Hana o ka Mīkini Honi i ka Hana ʻana i nā Bearing

3. Pehea e hoʻokō pono ʻia ai ke kaʻina hana hoʻonani

ʻO ka hana honing no nā bearings e pili ana i ka mea (ke apo i loko, ke apo o waho, a i ʻole ka lima), akā maʻamau e hahai i kēia mau pae:

Ka Papa 1: Hoʻomākaukau

Hoʻopaʻa ʻia ka mea hana (e laʻa me ke apo o loko) a hoʻopaʻa mua ʻia.

Hoʻopili ʻia ka wahi i hoʻonani ʻia (ʻo ka lua a i ʻole ke alanui heihei) ma kahimīkini honing horizontal or vertical honing machine.

KaʻAnuʻu Hana 2: Kau ʻana i ka Mea Hana Honing

A honing mandrel a i ʻole hui pōhakuhookomoia iloko o ka lua.

Aia ka mea paahanapohaku abrasive(diamond, CBN, a i ʻole alumini oxide) e hoʻonui radial e pili i ka ʻili.

KaʻAnuʻu Hana 3: Honing Action

ʻO ka mandrelkaʻawili a pānaʻii ka manawa like.

ʻO ka huirotary + reciprocatinghoʻopuka ka neʻe i kahi hoʻomalucrosshatch pattern.

Hoʻohana ʻia ke kaomi ʻai e hoʻonui mālie i nā pōhaku ke wehe ʻia nā mea.

Nā ʻāpana maʻamau:

Ka māmā holo: 100–600 rpm (hoʻololi)

Paʻi: 10–50 mm/s (ka pānaʻi)

Wehe ʻia ka waihona: 2–20 µm

KaʻAnuʻu Hana 4: Ana a me ka Manaʻo Manaʻo

I loko o nā laina kuhi pololei, i ka -kaʻina hana e hoʻohui pinepine ʻia.

Nānā 'ia ka nui o ka lua a me ka geometry i ka -manawa maoli, me ka ho'ololi 'akomi i ka hānai no ka mālama 'ana i ke ahonui.

KaʻAnuʻu Hana 5: Hoʻomaʻemaʻe a nānā

Ma hope o ka honing, hoʻomaʻemaʻe ʻia ka mea hana e wehe i nā abrasives a me nā koena aila.

Hōʻoia ka nānā ʻana i nā dimensional:

ʻO ke anawaena lua i loko o ±1 μm

Poe ʻAʻole i like a i ʻole 0.5 μm

ʻO ka pau ʻana o ka ʻili Ra ʻAʻole i like a i ʻole like me 0.1 μm

4. Nā Laʻana i nā ʻāpana Bearing

5. Hōʻuluʻulu manaʻo: No ke aha e pono ai ka Honing
