Maberani ang'onoang'ono - mbale zazing'ono zogwiritsidwa ntchito pazikulu

 

Ma berearing ang'onoang'onoOnani mndandanda wa metric, wokhala ndi mainchesi akunja osakwana 9mm; mndandanda wa Imperial, mitundu yonse ya mabearing okhala ndi mainchesi akunja osakwana 9.525mm. Zipangizo zazikulu ndi chitsulo choberera, chitsulo chosapanga dzimbiri, pulasitiki, ceramic, ndi zina zotero, zomwe mainchesi amkati mwa Z akhoza kukhala 0.6mm, ndipo mainchesi amkati mwathunthu ndi 1mm.

 

Mabearing a mpira waung'onoAmapangidwa ndi chitsulo cha kaboni, chitsulo chonyamula zinthu, chitsulo chosapanga dzimbiri, pulasitiki, zoumba ndi zinthu zina, zomwe zimagwiritsidwa ntchito mosiyanasiyana, zoyenera kuzungulira mwachangu, mphamvu yochepa yokangana, kugwedezeka kochepa, komanso phokoso lochepa (zipangizo zachitsulo cha kaboni sizigwiritsidwa ntchito kawirikawiri ndi makasitomala, kwa makasitomala otsika).

 

1. Makhalidwe a malonda

 

Ma berearing ang'onoang'onondi oyenera mitundu yonse ya zida zamafakitale, ma mota ang'onoang'ono ozungulira, ndi zina zotero; M'zaka zaposachedwapa, pakhala kuwonjezeka kwa kufunikira kwa mitundu ya zida izi zochepetsera kutentha, zopepuka, komanso zopyapyala.

 

Mu mabearing ang'onoang'ono a ultra-small bore miniature, pali mitundu 18 ya mabearing ang'onoang'ono okhala ndi mainchesi amkati a φ2mm kapena kuchepera, ndi mitundu 6 ya mndandanda wa Imperial R

 

2. Ntchito zazikulu

Zipangizo za muofesi Ma micro motors, ma soft drives Ma pressure rotors, ma dental drills Ma hard disk motors, ma stepper motors Zojambulira makanema Ng'oma zamaginito, mitundu ya zoseweretsa Mafani a makompyuta, ma encoder ndi zina.

 

3. Sankhani zinthu 11 za ma micro bearing

 

Posankha ma micro bearing, zinthu zambiri ziyenera kuganiziridwa kuti mupewe mtundu wosankhidwa ndi zolakwika zina, ndipo tsopano fotokozani mwachidule zinthu 11 zazikulu posankha ma micro bearing kuti mugwiritse ntchito.

 

1. Katundu wozungulira wocheperako

 

Maberiya omwe makamaka amanyamula katundu wa radial ndi maberiya apakati. Ndi ngodya yolumikizana ya A0≤45°, maberiya ozungulira a kukula komweko amatha kupirira katundu wokulirapo wa radial kuposa maberiya a mpira.

 

Ma bearing a roller a mtundu wa N ndi NU cylindrical amatha kunyamula katundu wozungulira wokha, pomwe mitundu ina ya ma bearing a centripetal imatha kunyamula katundu wozungulira wozungulira komanso wozungulira.

 

2. Katundu wa mabearing ang'onoang'ono a Axial

Bearing yomwe imanyamula katundu wa axial nthawi zambiri imakhala ngati thrust bearing, ndipo ngodya yake yolumikizirana ndi dzina lake ndi A0>45°. Ma thrust bearing ndi thrust angular contact ball bearing amatha kupirira mphamvu za axial mbali imodzi kapena zonse ziwiri nthawi imodzi, kutengera kapangidwe kake. Pamene mphamvu ya bearing ili yokwera kwambiri, ma thrust cylindrical roller bearing ndi thrust spherical roller bearing ndi omwe amakondedwa.

 

Ma bearing ozungulira ozungulira ndi ma bearing ozungulira ozungulira amatha kunyamula katundu wa axial ndi radial, pomwe ma bearing ena amatha kunyamula katundu wa axial okha.

 

3. Kulipira kutalika kwa chimbalangondo chaching'ono chochokera kunja chokha

 

Kuthandizira shaft ndi bearing nthawi zambiri kumagwiritsa ntchito kuphatikiza kwa bearing yokhazikika ndi bearing yoyendayenda. Ma bearing oyendayenda amalipira zolakwika pa kutalika kwa shaft ndi kukula kwa kutentha.

Ma bearing a NU ndi N cylindrical roller ndi ma bearing abwino oyendayenda omwe amakwaniritsa kutalika kwawo okha. Mphete zamkati ndi zakunja za bearing zitha kumangidwa bwino.

 

4. Kulipira kutalika kwa kukwanira kwa bere laling'ono

Ma bearing ang'onoang'ono osalekanitsidwa, monga ma bearing a mpira wozama ndi ma bearing ozungulira, angagwiritsidwenso ntchito ngati ma bearing oyendayenda. Chimodzi mwa ma ferrule awiri a mtundu uwu wa bearing chimagwirizanitsidwa ndipo chilibe malo olumikizira axial. Chifukwa chake, chimodzi mwa ma ferrule a bearing chingasunthidwe pamwamba pake.

 

5. Zolekanitsidwamabearing ang'onoang'ono(kulondola)

 

Ichi ndi chogwirira chomwe chingathe kukhazikitsidwa padera ndi ma ferrule, ndipo ubwino wake umawonekera kwambiri pamene ma ferrule onse awiri ali olimba.

 

Ma bearing olekanitsidwa amaphatikizapo ma bearing a mpira wolumikizana ndi mfundo zinayi, ma bearing a mpira wolumikizana ndi mizere iwiri yokhala ndi mphete ziwiri zamkati, ma bearing a cylindrical roller, ma bearing a roller opendekeka, ma bearing a mpira wopindika, ma bearing a roller a cylindrical, ndi ma bearing a roller ozungulira opindika.

 

Ma bearing osalekanitsidwa ndi awa: ma bearing a mpira wozama, ma bearing a mpira wolumikizana ndi mzere umodzi, ma bearing a mpira wozungulira, ndi ma bearing a roller ozungulira.

 

6. Kutengera pang'onokulondola

 

Nthawi zambiri, zimakhala zokwanira kugwiritsa ntchito ma bereji ozungulira a kukula kwakukulu komanso kulondola kozungulira.

 

Pamene zofunikira zili zapamwamba, ma bearing amafunika kulondola kwambiri.

 

7. Ma berearing ang'onoang'onomusamalipire kusalowerera ndale

Kusalingana kumachitika pokonza malo olumikizirana kapena malo olumikizirana, makamaka pamene malo olumikizirana sanamalizidwe ndi chinthu chimodzi. Kusalingana kungachitikenso pogwiritsa ntchito malo olumikizirana (monga malo olumikizirana kapena malo oimirira). Pamene shaft yapindika ndi kusokonekera chifukwa cha katundu wogwirira ntchito, zomwe zimapangitsa kuti mphete zamkati ndi zakunja za bearing zipendeke, kusalingana kudzachitikanso.

 

Ma bearing ozungulira amatha kubweza zolakwika ndi kupendekeka, monga ma bearing ozungulira mpira, ma bearing ozungulira a centripetal ndi thrust. Ma bearing awa ali ndi njira yozungulira yozungulira yomwe chinthu chozungulira ndi mphete yamkati zimatha kuzungulira. Kuthekera kwa ma bearing awa kubweza ngodya yapakati ya shaft kumadalira mtundu wawo, kukula, ndi mbiri yawo yonyamula katundu.

 

Ma bearing ozungulira ndi ma bearing a mpira othamanga omwe ali ndi ma race ali ndi malo ozungulira: ngodya yopindika imatha kusinthidwa ikayikidwa mu race yozungulira yopingasa.

 

8. Liwiro lonyamula laling'ono

Kukangana kwa ma bearing a mzere umodzi ndi kochepa kwambiri, kotero n'zotheka kufika pa liwiro la Z-high. Ma bearing awa amapezeka m'ma bearing a mpira wozama kwambiri omwe amatha kupirira katundu wa radial ndi ma bearing a mpira wolumikizana ndi angular omwe amatha kupirira katundu wophatikizana.

 

Kuti muwongolere kulondola kwa miyeso, kulondola kozungulira ndi kuyanjana kwa gawo la chogwirira, kugwiritsa ntchito njira zodzola ndi zoziziritsira, komanso kugwiritsa ntchito mitundu yapadera ya zikho kungapangitse kuti liwiro lozungulira la chogwiriracho liwonjezeke.

 

Ntchito ya phokoso lochepa

 

Phokoso lochepa la ntchito nthawi zambiri limafunika m'ma injini ang'onoang'ono, zida zaofesi ndi zida zapakhomo.

 

9. Kutengera pang'onodzenje lozungulira

Mabearing okhala ndi mabowo ozungulira amatha kuyikidwa mwachindunji ku majenali opindika (monga mabearing a single ndi double row cylindrical roller mu zomangamanga zolondola kwambiri). Mukayika mabearing awa, mtunda woperekedwa ukhoza kusinthidwa.

 

Ma bearing ambiri ozungulira, ma bearing a drum roller ndi ma bearing ozungulira okhala ndi bore yozungulira amatha kuyikidwa pa jenali yozungulira yokhala ndi chikwama cholimba. Ma bearing awa ndi osavuta kwambiri kuyika ndi kuchotsa.

 

10. Kuuma kwa mayendedwe ang'onoang'ono

 

Kuuma kwa ma bearing ochokera kunja nthawi zambiri kumatanthauza mphamvu yofunikira kuti pakhale kusintha kwina kwa bearing. Ma bearing pa spindle ndi pinion shaft ya makina amafunika kulimba kwambiri. Chifukwa cha kusiyana kwa momwe zinthu zimagwirizanirana pakati pa chinthu chozungulira ndi raceway, kuuma kwa ma bearing ozungulira kumakhala kwakukulu kuposa kwa ma bearing a mpira.

 

11. Kukangana kwa microbearing

 

Kuwonjezera pa kutentha ndi kutayikira, kukangana kwamkati kumachitanso gawo lofunika kwambiri podziwa kutentha kwa bearing. Ma bearing otsika a friction ndi awa: ma bearing a mpira wozama kwambiri okhala ndi ma radial loads, ma bearing angular contact ball bearing angular ndi ma bearing a cylindrical roller okhala ndi ma cages. Ma bearing otsekedwa ndi contact-sealed, ma bearing a cylindrical roller bearing odzaza mokwanira, ndi ma bearing a thrust roller onse amapanga kukangana kwakukulu.
