He aha ka Bearing?

No ka bea ka hua'ōlelo bearing, ʻo ia hoʻi ke kākoʻo a amo paha.

Ke hoʻoikaika ʻia ka ʻaoʻao ma waena o ʻelua ʻāpana a inā kākoʻo kekahi ʻāpana i kekahi, ʻike ʻia ka ʻaoʻao kākoʻo he bearing.

No laila, ʻo ka bearing kahi ʻāpana mīkini o kahi ʻāpana mīkini e kākoʻo ana i kahi ʻāpana mechanical ʻē aʻe a i ʻole ʻāpana e pili ana me ia.

He laina laina a rotary paha ka neʻe pili.

E like me ke ʻano o ke poʻo ʻenekini a me nā alakaʻi, hana nā alakaʻi e like me nā bearings a ʻo ka neʻe pili ʻana he laina laina. Pēlā nō, hiki ke mālama ʻia nā ala o nā mīkini wili a me nā mīkini planar e like me nā bearings.

E like me na wiliwili o ka lathe, wili a me na mikini hooluu, axles o na kaa, crankshafts, etc.

Pono no nā Bearings.

Ma kahi kokoke i nā ʻano mīkini a pau, pono e hoʻouna ʻia ka neʻe a i ʻole ka mana ma o nā ʻāpana wili, ʻo ia hoʻi e paʻa ʻia e nā bearings.

Hāʻawi kēia mau bearings i ka hoʻololi manuahi a maʻalahi o nā kumu me ka liʻiliʻi liʻiliʻi. Hiki ke hōʻemi ʻia ka nalo ʻana o ka mana a i ʻole ka neʻe ʻana me ka lubrication kūpono o nā ʻili halihali.

ʻO ka pono a i ʻole ka pono o nā bearings no nā kumu ʻelua.

1. No ka hāʻawi ʻana i ke kākoʻo i nā lāʻau wili.

2. No ka ʻae ʻana i ka hoʻololi manuahi a maʻalahi o nā kumu.

3. E amo i ka hookui a me na ukana radial.

Nā ʻano o ka lawe ʻana.

ʻO ka maʻamau, hiki ke hoʻokaʻawale ʻia nā bearings i ʻelua ʻano penei:

1. ʻO nā bearings pili ʻana a me ka;

2. ʻO nā bearings pili kaʻa a i ʻole nā ​​​​pahu anti-friction.

1. Hoʻoheheʻe Hoʻopili Bearings;

He neʻe koʻikoʻi ko nā bearings pili a me nā kumu ma muli o ko lākou heʻe ʻana e pili ana i kekahi i kekahi. Ma keʻano laulā, hiki ke kapa ʻia nā bearings a pau ʻaʻole i hoʻohana i nā wili a me nā pōpō e like me nā bearings contact sliding.

Hoʻokaʻawale ʻia ʻo Sliding Contacts Bearings i nā ʻano like.

i. Laina pololei a alakai paha;

Inā like ke kuhikuhi o ka neʻe pili a me ka hoʻoheheʻe ʻana o nā ʻili, ʻike ʻia ka ʻaoʻao ʻo ka laina pololei a i ʻole alakaʻi alakaʻi e laʻa, nā alakaʻi ma nā poʻo keʻa ʻenekini, nā ala o nā mīkini wili a me nā milo o nā mīkini wili a me nā mīkini ʻoluʻolu.

ii. ʻO Radial a i ʻole ka puke moʻolelo;

Inā he rotary ka neʻe pili ma waena o ka lāʻau a me ke kau ʻana a inā pili ka ukana i ke koʻi o ke kumu a i ʻole ma ka radius o ka lāʻau, ua ʻike ʻia ka bearing he journal bearing a radial bearing.

ʻO ka ʻāpana o ke kumu i hoʻopaʻa ʻia e ka bearing i ʻike ʻia he puke pai.

iii. Hāpai ʻia;

Inā like ka ukana ma luna o ke kuʻi me ke koʻi o ka lāʻau, ua ʻike ʻia ka bearing ma ke ʻano he pahu pahu.

iv. Ka wāwae wāwae a i ʻole ka Pivot Bearing;

Ma ke kuʻi ʻana, inā e pau ka hopena o ke kumu ma ka hoʻomaha ʻana ma luna o ka ʻili o ke kuʻekuʻe, ʻike ʻia ʻo ia ka wāwae wāwae a i ʻole ka pivot bearing.

v. Hāpai Kola;

Ma ke kuʻi ʻana, inā e hoʻolōʻihi ʻia nā wēlau o ka lāʻau ma waho a ma o ka ʻili o ke alo, ua ʻike ʻia ʻo ia ʻo ke kolar bearing. ʻO ke koʻi o ka lāʻau e noho paʻa.

vi. Kūleʻa Puhi;

Hōʻike ʻia ke ʻano maʻalahi o ka bearing bushed ma ##Fig. 1.8 lalo. Aia i loko o ke kino hao hao a me ka nahele i hana ʻia me ke keleawe a i ʻole ka pū.

He kumu huinahā ko ke kino. Hana ʻia ke kumu i awāwa e hōʻemi i ka ʻāpana ʻili o ka mīkini. Hāʻawi ʻia ʻelua puka elliptical ma ke kumu no ka hoʻopaʻa ʻana i ka bearing.

Hāʻawi ʻia kahi lua aila ma luna o ke kino e holo ana ma ka nahele. No laila, hiki ke hana i ka lubrication no ka lāʻau a me ka nahele ma ka lua aila.

Ua like ke anawaena o loko o ka nahele me ke anawaena o ke kumu. Hoʻopaʻa ʻia ka lāʻau e kahi wīwī grub i pale ʻia kona hoʻololi ʻana a i ʻole ka paheʻe ʻana me ka shaft.

Inā pau ka lāʻau, hoʻololi ʻia e kahi mea hou. Hiki ke hoʻokomo ʻia ke kumu i loko o ka bearing end-wise. ʻO kēia kekahi o nā hemahema o kēia bearing.

Loaʻa ka hoʻohana ʻana o Bushed bearing i nā haʻawe māmā a me nā māmā haʻahaʻa.

vii. Pedestal Bearing;

Ua ʻike nui ʻia ʻo Plummer block i ka piʻi wāwae. Ua kapa ʻia ʻo ia he puʻupuʻu puʻupuʻu mahele a mahele paha.

Loaʻa iā ia kahi poloka hao i kapa ʻia ʻo pedestal, kahi pāpale hao hao, nā keleawe pū i loko o ʻelua ʻāpana, ʻelua mau poʻo poʻo huinaha kila māmā a me ʻelua pūʻulu o nā nati laka hexagonal e like me ka hōʻike ʻana ma ka ##Fig. 1.9 ma lalo.

ʻO ke ʻano o ka bearing he ʻano māhele; hanaia i elua hapa.

Ua kapa ʻia ka ʻaoʻao o luna i ka pāpale, i hoʻopaʻa ʻia i ke kino nui i kapa ʻia ʻo pedestal ma o nā bolts poʻo ʻehā a me nā nati hexagonal.

ʻO kēia māhele ʻana a i ʻole ka hoʻokaʻawale ʻana i ka hali e hoʻomaʻamaʻa maʻalahi i ka waiho ʻana a me ka wehe ʻana i ke kumu a me nā ʻāpana o ka nahele.

Ua ʻike ʻia nā lāʻau ʻāpana he keleawe a i ʻole nā ​​ʻanuʻu.

Hāʻawi ʻia kahi snug i loko o kahi lāʻau haʻahaʻa haʻahaʻa i kūpono i loko o ka lua i hāʻawi ʻia i loko o ke kino.

No laila ua pale ʻia ka hoʻololi ʻana o ka lāʻau me ka lāʻau, a pale ʻia ka neʻe ʻana o ke axial e nā flanges collar ma nā wēlau.

He keleawe, keleawe, metala keʻokeʻo, etc.

Noho ka lāʻau ma luna o ka lāʻau maʻi lalo. Hoʻokomo ʻia ka lāʻau ʻoki luna ma luna o ke kumu, a ma hope, ua paʻa ka pāpale.

Ua waiho ʻia kahi ʻokoʻa liʻiliʻi ma waena o ka pāpale a me ke kino e kōkua i ka wā e hoʻohaʻahaʻa ʻia ai ka pāpale ma muli o ka hoʻopakele ʻana i ka nahele me nā linings hou.

ʻIke ʻia kēia bearing i kona hoʻohana ʻana i ka wikiwiki kiʻekiʻe a me nā ʻaoʻao like ʻole o ka ukana.

viii. Hali wāwae wāwae a i ʻole Pivot bearing.

Ma ka wāwae wāwae a i ʻole ka pivot bearing, hana like ke kaomi me ke koʻi o ke kumu a kau ʻia ka lāʻau i ke kuʻi ma kona ʻaoʻao hoʻokahi.

Loaʻa iā ia he poloka pōʻai poʻo a i ʻole kino me kahi kumu ʻāʻī a me kahi lāʻau pū, e like me ka mea i hōʻike ʻia ma ka ##Fig. 1.10 ma lalo.

Loaʻa i ka poloka ka hopena hāmama kahi i hoʻokomo ʻia ai ke kumu. Kau pololei ka lāʻau ma luna o kahi diski kila me ka hoʻopuehu concave.

Kāohi ʻia ka disc mai ka hoʻololi ʻana me ke kumu ma ke ʻano o kahi pine i hoʻokomo ʻia ka hapalua i loko o ka disc a me ke kino.

Kāohi ʻia ka hoʻololi ʻana o ka lāʻau me ke kumu ma ke ʻano o ka snug i hāʻawi ʻia ma kona ʻāʻī ma lalo pono o ke kola.

Loaʻa kēia mau bearings i nā noi i ka mīkini o nā textiles, pepa, a me nā mea ʻē aʻe, i hoʻohana ʻia no nā ukana māmā a me nā wikiwiki haʻahaʻa.

I ka lawe ʻana i nā kapuaʻi, paʻakikī ka lubrication no ka mea e hoʻolei ʻia ka ʻaila i waho mai ke kikowaena e ka ikaika centrifugal.

2. Nā Bearings Hoʻopili ʻO Rolling a i ʻole Anti-friction Bearings.

I ka ʻōwili ʻana i nā bearings pili, ʻo ka neʻe pili ʻana ma waena o ke kumu a me ka bearings ke kumu ma muli o ka ʻōwili ʻana o nā pōpō a me nā wili i hoʻohana ʻia i nā bearings.

No laila, ua kapa ʻia kēia mau mea he rolling contact bearings a i ʻole ball a roller bearings.

ʻOi aku ka liʻiliʻi o ke kuʻekuʻe ʻana ma mua o ka paheʻe ʻana i nā bearings pili, a ʻoi aku ka liʻiliʻi o ka abrasion o nā mīkini e koi pinepine ai e hoʻomaka a kū ma lalo o ka ukana.

No laila, ua kapa ʻia kēia mau bearings he anti-friction bearings.

Aia ʻelua ʻano o nā bearings anti-friction, a ʻo lākou;

1. ʻO nā kinipōpō a me;

2. ʻO ka huila.

i. Huina poepoe;

Hoʻohana ʻia nā pōpō pōʻai i nā bearings.

Aia ʻelua ʻano o nā ʻano kinipōpō;

(i) Uku kinipopo Radial a me (ii) Hoʻokuʻu ʻia i nā bearings kinipōpō.

Piʻi kinipopo Radial hoʻohana ʻia no ka lawe ʻana i nā haʻahaʻa radial a i ʻole nā ​​ukana e kū pono ana i ke koʻi o nā kumu, ʻoiai ke hoʻohana ʻia nei nā pahu pahu no nā haʻalulu, ʻo ia hoʻi, nā ukana e hana like ana me ke axis o ke kumu.

Hoʻokuʻu ʻia i nā bearings kinipōpō hoʻohana ʻia no ka lawe ʻana i nā haʻahaʻa hoʻopaʻa ma nā kumu.

He poepoe kila paakiki lakou i hoonohoia mawaena o na heihei elua. He mau apo kila paakiki na heihei. Hoʻololi kekahi lāhui me ke kumu, a paʻa kekahi i loko o ka hale bearing.

Mālama ʻia nā pōpō i ke kūlana ma o nā hīnaʻi. ʻO nā hīnaʻi nā mea hoʻokaʻawale o nā kinipōpō i hana ʻia me ke keleawe paʻi ʻia.

Hōʻike ʻia ka hoʻonohonoho ʻana o ke kuʻi maʻalahi ma ##Fig. 1.11 ma lalo. Hoʻohana ʻia nā bearings pōpō pana a hiki i ka wikiwiki o 2000 rpm.

No ka wikiwiki o ka hoʻouka ʻana, hoʻohana ʻia nā bearings ball contact angular. Ma lalo o ka wikiwiki kiʻekiʻe, hoʻokuʻu ʻia nā pōpō i waho o nā heihei ma muli o ka ikaika centrifugal i hoʻomohala ʻia i loko o nā bearings thrust.

ii. Huina Roller;

Hiki ke hoʻokaʻawale ʻia nā huila wili e like me ka radial roller bearings a me ka thrust roller bearings. Lawe ʻia nā bearings radial a me thrust roller bearings i kēlā me kēia.

Hiki ke hoʻokaʻawale ʻia kēia mau bearings ʻelua ma ke kumu o nā ʻano wili i hoʻohana ʻia, e like me nā bearings rol cylindrical, nā bearings needle roller, a me nā bearings roll tapered.

Ke hoʻohālikelike ʻia me nā bearings, ʻoi aku ka nui o ka paʻa ʻana o nā huila wili akā ʻoi aku ka nui o ka ukana. No nā noi haʻahaʻa māmā, hoʻohana ʻia nā bearings pōpō nona ka mālama ʻana i ʻoi aku ka liʻiliʻi ma mua o ka nui o nā bearings roller.

Eia naʻe, inā he kaumaha ka ukana a hiki ke hoʻouka ʻia nā bearings, hoʻohana wale ʻia nā bearings.

Nā pōmaikaʻi a me nā pōʻino o ka pōleʻa a me nā huila;

Ke hoʻohālikelike ʻia me nā bearings sliding contact bearings, loaʻa nā mea maikaʻi a me nā pōʻino ʻole.

Nā pono.

1. He haʻahaʻa ka hoʻomaka ʻana a me ka holo ʻana.

2. He maʻalahi ka hoʻololi.

3. Hiki ke hoʻohana ʻia no nā ukana radial a axial.

4. He maʻalahi ka lubrication.

5. He haʻahaʻa ke kumukūʻai mālama.

Nā pōʻino.
