Bearing sinayikidwe bwino. Vutoli ndi lalikulu kwambiri!

Kusonkhanitsa ma berea otsetsereka

Ma bearing otsetsereka ndi mtundu wa bearing wokhala ndi makhalidwe otsetsereka otsetsereka. Amadziwika ndi ntchito yosalala, kudalirika, phokoso lochepa, komanso kuthekera kopirira katundu wolemera komanso katundu wofunika kwambiri. Malinga ndi mitundu yosiyanasiyana ya kapangidwe kake, amatha kugawidwa m'magulu awiri: mtundu wophatikizika, mtundu wogawanika, ndi mtundu wa block, ndi zina zotero.

1. Kusonkhanitsa ma berea otsetsereka ofunikira

Maberiya otsetsereka ophatikizana, omwe amadziwika kuti ma bushings, ndi njira yosavuta kwambiri yotsetsereka. Amasonkhanitsidwa makamaka pokanikiza mkati ndi kuponda. Nthawi zina, njira yokwezera yotentha imagwiritsidwa ntchito. Ma bushings ambiri amapangidwa ndi mkuwa kapena chitsulo chopangidwa ndi chitsulo.
    
Pa nthawi yosonkhanitsa, muyenera kusamala. Zitha kusonkhana pozimenya ndi nyundo yamatabwa kapena nyundo yokhala ndi chipika chamatabwa. Ngati kulekerera kusokoneza kuli kwakukulu, ziyenera kukakamizidwa ndi kukanikiza. Kaya zagwetsedwa kapena zalowetsedwa, kupendekeka kuyenera kupewedwa. Pambuyo posonkhanitsa, mpata wamafuta ndi dzenje lamafuta ziyenera kukhala pamalo oyenera.
    
Pa mabearing ofooka atasonkhanitsidwa, mabowo amkati ayenera kudulidwa. Pa ang'onoang'ono, ma reamer angagwiritsidwe ntchito podula; pa akuluakulu, ma scraper ayenera kugwiritsidwa ntchito. Nthawi yomweyo, samalani ndi kuwongolera malo olumikizirana ndi shaft mkati mwa mulingo woyenera kupirira.
    
Pofuna kupewa kuti chigoba cha shaft chisazungulire panthawi yogwira ntchito, ma pini oikira kapena zomangira zopingasa zimayikidwa pamalo olumikizirana pakati pa chigoba cha shaft ndi nyumbayo. Chifukwa cha kuuma kosiyana kwa thupi la bokosi ndi zipangizo za chigoba cha shaft, pobowola, zimakhala zosavuta kuti chobowolacho chiziyang'ana mbali yofewa ya zinthu. Mayankho ake ndi awa:
* Choyamba, gwiritsani ntchito chitsanzo cha kubowola dzenje kumbali yolimba musanaboole.
* Chachiwiri, gwiritsani ntchito chobowola chachifupi kuti muwonjezere kulimba kwa chobowolacho panthawi yobowola.

2. Kusonkhanitsa mabearing ogawanika

Ma bearing ogawanika, omwe amadziwikanso kuti ma bearing ogawanika, ali ndi kapangidwe kosavuta ndipo ndi osavuta kusintha ndikuchotsa. Ma bearing shells awiri amaikidwa pa ma bearing shells, ndipo gasket imagwiritsidwa ntchito pamalo olumikizirana kuti asinthe mpata woyenera.

*A. Kusonkhanitsa chitsamba choberekera ndi Nyumba Yonyamula
Kulumikizana pakati pa zipolopolo za pamwamba ndi pansi ndi dzenje lamkati la chipolopolo cha bearing kuyenera kukhala kwabwino. Ngati sichikukwaniritsa zofunikira, gwiritsani ntchito dzenje lamkati la chipolopolo cha bearing shell chokhala ndi makoma olimba ngati chizindikiro cha kukanda kumbuyo kwa chipolopolo cha bearing. Nthawi yomweyo, masitepe awiri kumapeto onse a chipolopolo cha bearing shell ayenera kukhala pafupi ndi malekezero awiri a chipolopolo cha bearing shell. Pa zipolopolo za bearing shell zokhala ndi makoma ochepa, ndikofunikira kupanga midplane ya chipolopolo cha bearing pafupifupi 0.1mm kuposa ya chipolopolo cha bearing shell, ndipo palibe chifukwa chochikanda.
    
*B. Zofunikira pa malo
Chitsamba chonyamulira chimayikidwa m'nyumba yonyamulira ndipo sichiloledwa kukhala ndi kusuntha kulikonse kaya mozungulira kapena mozungulira. Nthawi zambiri, chimayimitsidwa ndikuyikidwa ndi masitepe kumapeto onse a chitsamba chonyamulira kapena pogwiritsa ntchito mapini oyika.
    
*C. Kukwapula kwa zipolopolo zonyamulira
Pa zipolopolo zogawanika, malo opukutira shaft ofanana amagwiritsidwa ntchito. Nthawi zambiri, chipolopolo chonyamulira chimachotsedwa kaye, kenako chipolopolo chapamwamba chimachotsedwa. Kuti zigwire bwino ntchito, chipolopolo chonyamulira ndi chivundikiro sizifunika kuyikidwa pochotsa chipolopolo chonyamulira. Pamene malo olumikizirana a chipolopolo chapansi chonyamulira akukwaniritsa zofunikira, chipolopolo chapamwamba chonyamulira ndi chivundikiro chapamwamba zimakanikizidwa mwamphamvu. Pochotsa chipolopolo chapamwamba chonyamulira, malo olumikizirana a chipolopolo chapansi chonyamulira amakonzedwanso. Pochotsa, kulimba kwa shaft kumatha kusinthidwa mwa kusintha makulidwe a gasket pamene kuchuluka kwa nthawi zokwawa kumawonjezeka. Pamene Chivundikiro Chonyamula yakhazikika, shaft imatha kuzungulira momasuka popanda kuonekera bwino, ndipo malo olumikizirana akukwaniritsa zofunikira, kukwapula kwatha.
    
*D. Kuyeza kwa chilolezo chonyamula katundu
Kukula kwa malo operekera bearing kungasinthidwe ndi gasket pakati pa ndege kapena pokanda mwachindunji chitsamba choperekera bearing. Malo operekera bearing nthawi zambiri amayesedwa ndi njira yokanikiza lead:
1. Tengani magawo angapo a waya wa lead wokhala ndi mainchesi akuluakulu kuposa malo operekera katundu
2. Ziikeni pa jenali ndi pamwamba pa malo olekanitsira pakati
3. Limbitsani nati kuti mukanikize bwino malo olekanitsira pakati
4. Tsegulani nati ndikuchotsa chivundikiro cha bere
5. Chotsani mosamala waya wopyapyala wa lead
6. Gwiritsani ntchito micrometer kuti muyese makulidwe a gawo lililonse
        
Kutengera makulidwe apakati a waya wotsogolera, malo operekera chithandizo amatha kudziwika. Malo operekera chithandizo ayenera kukhala 1.5-2.5 mm (mm) ya m'mimba mwake wa shaft. M'mimba mwake mukakhala waukulu, malo operekera chithandizo ayenera kukhala ochepa. Ngati m'mimba mwake wa shaft ndi 60 mm, malo operekera chithandizo ayenera kukhala pakati pa 0.09 ndi 0.15 mm.

Kusonkhanitsa mabearing ozungulira

Mabearing ozungulira ali ndi ubwino wa kukangana kochepa, kukula kochepa kwa axial, kusintha kosavuta komanso kukonza kosavuta.

Zofunikira zaukadaulo pakupangira:

* Mapeto a mabearing ozungulira okhala ndi ma code ayenera kuyikidwa mbali yooneka kuti zitsimikizire bwino panthawi yosintha.
* Utali wa arc pa sitepe ya journal kapena housing earth uyenera kukhala wocheperako kuposa womwe uli pamalo ofanana pa bearing.
* Pambuyo poti bearing yasonkhanitsidwa pa shaft ndi m'dzenje la nyumba, sipayenera kukhala chopinga.
* Pakati pa mabearing awiri omwe ali pa mzere umodzi, munthu ayenera kuyambitsa shaft kusuntha pamene shaft ikukula motentha.
* Polumikiza ma bearing ozungulira, ndikofunikira kwambiri kuti dothi lisalowe m'ma bearing.
* Pambuyo pomanga, mabearing ayenera kugwira ntchito mosinthasintha, kupanga phokoso lochepa, ndipo kutentha kwa ntchito nthawi zambiri sikuyenera kupitirira 65℃.
