Nā bearings liʻiliʻi - nā papa kino liʻiliʻi no nā hoʻohana nui

 

Nā bearings liʻiliʻiE pili ana i ka moʻo metric, me ke anawaena waho ma lalo o 9mm; ʻO ka moʻo Imperial, nā ʻano bearings āpau me ke anawaena waho ma lalo o 9.525mm. ʻO nā mea nui e halihali ana i ke kila, ke kila kila, ka plastic, ka seramika, a pēlā aku, nona ke anawaena o loko Z he 0.6mm, a ʻo ke anawaena o loko maʻamau he 1mm.

 

Nā mea hoʻopaʻa pōpō liʻiliʻiHana ʻia me ke kila kalapona, ke kila hali, ke kila kila, ka plastic, nā keramika a me nā mea ʻē aʻe, me kahi ākea o nā hoʻohana, kūpono no ka wili wikiwiki, ka torque friction haʻahaʻa, ka haʻalulu haʻahaʻa, nā koi walaʻau haʻahaʻa (ʻaʻole hoʻohana pinepine ʻia nā mea kila kalapona e nā mea kūʻai aku, no nā mea kūʻai aku haʻahaʻa).

 

1. Nā ʻano huahana

 

Nā bearings liʻiliʻikūpono no nā ʻano lako hana ʻoihana āpau, nā motika rotary liʻiliʻi, a pēlā aku; I nā makahiki i hala iho nei, ua hoʻonui ʻia ke koi no ka miniaturization, māmā, a me nā ʻano lahilahi o kēia mau mea hana.

 

I loko o nā bearings miniature liʻiliʻi loa, aia he 18 mau ʻano o nā bearings micro me ke anawaena o loko o φ2mm a i ʻole ka liʻiliʻi, a me 6 mau ʻano o ka moʻo imperial R.

 

2. Nā hoʻohana nui

Nā lako keʻena Nā motika micro, nā ʻauʻau palupalu Nā rotors kaomi, nā wili niho Nā motika paʻa paʻa, nā motika stepper Nā mea hoʻopaʻa wikiō Nā pahu magnetic, nā mea pāʻani Nā peʻahi kamepiula, nā encoders a me nā kahua ʻē aʻe.

 

3. E koho i 11 mau mea o nā bearings micro

 

I ke koho ʻana i nā bearings micro, pono e noʻonoʻo ʻia nā kumu he nui e pale aku i ke ʻano koho a me nā hewa ʻē aʻe, a i kēia manawa e hōʻuluʻulu i nā mea nui he 11 o ke koho ʻana i nā bearings micro no kāu kuhikuhi.

 

1. Ukana radial liʻiliʻi

 

ʻO nā bearings e halihali nui ana i nā ukana radial he mau bearings centripetal. Me kahi kihi pili maʻamau o A0≤45°, hiki i nā bearings wili o ka nui like ke kū i nā ukana radial nui aʻe ma mua o nā bearings pōpō.

 

Hiki i nā bearings wili cylindrical N-type a me NU ke halihali i nā ukana radial wale nō, ʻoiai ʻo nā ʻano bearings centripetal ʻē aʻe ke halihali i nā ukana radial a me axial.

 

2. Ka ukana axial o nā bearings liʻiliʻi

ʻO ke kaulahao e halihali nui ana i nā ukana axial he kaulahao thrust ia, a ʻo kona kihi pili inoa A0>45°. Hiki i nā kaulahao thrust a me nā kaulahao pōpō hoʻopili angular thrust ke kū i nā ikaika axial i hoʻokahi a i ʻole nā ​​ʻaoʻao ʻelua i ka manawa like, ma muli o ke ʻano. Ke kiʻekiʻe loa ka ikaika o ke kaulahao, makemake ʻia nā kaulahao wili cylindrical thrust a me nā kaulahao wili spherical thrust.

 

Hiki i nā bearings wili poepoe thrust a me nā bearings pōpō hoʻopili angular thrust unidirectional ke hali i nā ukana axial a me radial, ʻoiai ʻo nā bearings thrust ʻē aʻe hiki ke hali i nā ukana axial wale nō.

 

3. ʻO ka uku lōʻihi o ka micro imported bearing ponoʻī

 

ʻO ke kākoʻo ʻana i kahi ʻau a me ka bearing e hoʻohana pinepine i ka hui pū ʻana o ka bearing paʻa a me ka bearing huakaʻi. Hoʻoponopono nā bearing huakaʻi no nā hewa o ka lōʻihi o ke ʻau a me ka hoʻonui ʻana o ka wela.

ʻO nā bearings wili cylindrical NU a me N nā bearings huakaʻi kūpono e hoʻoponopono i ka lōʻihi ma o lākou iho. Hiki ke hoʻopaʻa pono ʻia nā apo o loko a me waho o ka bearing.

 

4. Ka uku lōʻihi no ke kūpono paheʻe o ka bearing miniature

Hiki ke hoʻohana ʻia nā bearings liʻiliʻi hiki ʻole ke hoʻokaʻawale ʻia, e like me nā bearings ball groove hohonu a me nā bearings roller spherical, ma ke ʻano he bearings huakaʻi. Hoʻopili ʻia kekahi o nā ferrules ʻelua o kēia ʻano bearing a ʻaʻohe ʻili hoʻopaʻa axial. No laila, hiki ke hoʻoneʻe ʻia kekahi o nā ferrules o ka bearing ma luna o kona ʻili bearing.

 

5. Hiki ke hoʻokaʻawale ʻianā bearings liʻiliʻi(pololei)

 

He bearing kēia e hiki ke hoʻokomo ʻokoʻa ʻia me nā ferrules, a ʻike nui ʻia kona mau pono ke hoʻopaʻa pono ʻia nā ferrules ʻelua.

 

ʻO nā bearings hiki ke hoʻokaʻawale ʻia e komo pū me nā bearings pōpō pili ʻehā-kiko, nā bearings pōpō pili kihi pālua lālani me nā apo hapalua pālua o loko, nā bearings wili cylindrical, nā bearings wili tapered, nā bearings pōpō thrust, nā bearings wili cylindrical thrust, a me nā bearings wili poepoe thrust.

 

ʻO nā bearings hiki ʻole ke hoʻokaʻawale ʻia: nā bearings pōpō hohonu hohonu, nā bearings pōpō hoʻopili kihi lālani hoʻokahi, nā bearings pōpō poepoe, a me nā bearings wili poepoe.

 

6. ʻO ka hali liʻiliʻipololei

 

I ka hapanui o nā hihia, ua lawa ka hoʻopili ʻana i nā bearings wili o ka nui maʻamau a me ka pololei o ka wili ʻana.

 

Ke kiʻekiʻe aʻe nā koi, pono nā bearings i nā helu pololei kiʻekiʻe aʻe.

 

7. Nā bearings liʻiliʻimai uku no ke kūlike ʻole

Hiki ke kū ʻole ke ʻano i ka wā e hana ana i ka mīkini ʻana i ka ʻili pili puke pai a i ʻole ka ʻili pili hale, ʻoiai inā ʻaʻole i hoʻopau ʻia ka ʻili pili i hoʻokahi kau ʻana. Hiki nō hoʻi ke kū ʻole ke ʻano i ka wā e hoʻohana ai i nā hale (no ka laʻana, nā hale flange a i ʻole nā ​​hale kū pololei). Ke kūlou a hoʻololi ʻia ke koʻokoʻo ma muli o ka ukana hana, e hopena ana i ke kūlou ʻana o nā apo o loko a me waho o ka bearing, e kū pū kekahi ka kū ʻole.

 

Hiki i nā bearings poepoe ke hoʻoponopono no ka hewa a me ke kūlou ʻana, e like me nā bearings poepoe poepoe, nā bearings centripetal a me nā thrust spherical roller bearings. Loaʻa i kēia mau bearings kahi ala holo apo poepoe waho concave kahi e hiki ai i ka mea ʻōwili a me ke apo o loko ke wili. ʻO ka hiki o kēia mau bearings ke hoʻoponopono no ke kihi deflection waena o ke koʻokoʻo e pili ana i ko lākou ʻano ponoʻī, ka nui, a me ke ʻano ukana.

 

Loaʻa i nā bearings poepoe ʻelua a me nā bearings pōpō hoʻokuʻi me nā heihei kahi ʻilikai bearing poepoe: hiki ke hoʻoponopono ʻia ke kihi deflection i uku ʻia i ka wā e hoʻokomo ʻia ai i loko o kahi heihei poepoe concave.

 

8. Ka wikiwiki o ka halihali liʻiliʻi

He haʻahaʻa loa ka friction o nā bearings lālani hoʻokahi, no laila hiki ke hiki i nā wikiwiki Z-kiʻekiʻe. Loaʻa kēia mau bearings i nā bearings ball groove hohonu hiki ke kū i nā ukana radial a me nā bearings ball contact angular hiki ke kū i nā ukana i hui pū ʻia.

 

No ka hoʻomaikaʻi ʻana i ka pololei o ka dimensional, ka pololei o ka wili a me ka ʻāpana male o ka beaver, ka hoʻohana ʻana i nā ʻano lubrication a me nā hoʻomaʻalili, a me ka hoʻohana ʻana i nā ʻano cages kūikawā e hoʻonui i ka wikiwiki o ka wili ʻana o ka beaver.

 

Hana walaʻau haʻahaʻa

 

ʻO ka mea maʻamau, pono ka walaʻau hana haʻahaʻa i nā motika liʻiliʻi, nā lako keʻena a me nā lako hale.

 

9. ʻO ka hali liʻiliʻipuka ʻōniʻoniʻo

Hiki ke hoʻopili pololei ʻia nā bearings me nā lua conical i nā journal tapered (e laʻa me nā bearings cylindrical lālani hoʻokahi a me ʻelua i nā kūkulu kikoʻī kiʻekiʻe). I ke kau ʻana i kēia mau bearings, hiki ke hoʻoponopono ʻia kahi radial clearance i hāʻawi ʻia.

 

Hiki ke hoʻopaʻa ʻia ka hapa nui o nā bearings poepoe poepoe, nā bearings wili pahu a me nā bearings wili poepoe me ka lua conical i kahi puke pai cylindrical me kahi lima paʻa. He maʻalahi loa kēia mau bearings e hoʻouka a wehe.

 

10. ʻOʻoleʻa o ka hali liʻiliʻi

 

ʻO ke ʻano paʻakikī o nā bearings i lawe ʻia mai e pili ana i ka ikaika e pono ai e hana i kahi deformation elastic o ka bearing. Pono nā bearings ma ka spindle mīkini a me ke koʻokoʻo pinion i kahi kiʻekiʻe o ka paʻakikī. Ma muli o nā kūlana pili like ʻole ma waena o ka element wili a me ke ala holo, ʻoi aku ke kiʻekiʻe o ka paʻakikī o nā bearings roller ma mua o nā bearings pōpō.

 

11. Ka ʻūlū ʻana o ka micro bearing

 

Ma waho aʻe o ka hoʻomehana ʻia a me ka hoʻoheheʻe ʻia ʻana, he kuleana koʻikoʻi nō hoʻi ka friction kūloko i ka hoʻoholo ʻana i ka mahana hana o ka bearing. ʻO nā bearings friction haʻahaʻa: nā bearings pōpō groove hohonu me nā ukana radial, nā bearings pōpō hoʻopili angular hoʻokahi lālani liʻiliʻi a me nā bearings roller cylindrical me nā cages. ʻO nā bearings i hoʻopaʻa ʻia me ka pilina, nā bearings roller cylindrical i hoʻouka piha ʻia, a me nā bearings roller thrust a pau e hoʻoulu i ka friction kiʻekiʻe.
