Bearing sinayikidwe bwino. Vutoli ndi lalikulu kwambiri!

Ogwiritsa ntchito nthawi zonse amadandaula za nthawi yogwira ntchito ya ma bearing, koma 80% ya ma bearing amalephera msanga chifukwa cha kuyika kolakwika. Kuyika bwino ma bearing sikungowonjezera nthawi yogwira ntchito yawo ndikuchepetsa ndalama, komanso kumawonjezera kwambiri magwiridwe antchito.

Monga momwe zimadziwikira, ma bearing okha ndi zinthu zomwe zimagwiritsidwa ntchito pothandizira komanso ndi zinthu zomwe zimagwiritsidwa ntchito pothandizira kuzungulira kwa ma shaft. Ma bearing amatha kugawidwa m'magulu malinga ndi momwe amakhalira ndi ma bearing otsetsereka ndi ma rolling bearing. Malinga ndi momwe katundu wawo umayendera, pali ma radial bearing, Kunyamulas, ndi ma radial thrust bearing, ndi zina zotero.

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 bere otsetsereka ofunikira

Maberiya otsetsereka ophatikizana, omwe amadziwika kuti ma bushings, ndi njira yosavuta kwambiri yotsatsira ma beriya. Amasonkhanitsidwa makamaka pokanikiza mkati ndi kuponya. Nthawi zina, njira yoyikamo yotentha imagwiritsidwa ntchito. Ma bushings ambiri amapangidwa ndi mkuwa kapena chitsulo chopangidwa ndi chitsulo. Pakusonkhanitsa, muyenera kusamala. Amatha kusonkhana pomenya ndi nyundo yamatabwa kapena nyundo yokhala ndi chipika chamatabwa. Ngati kulekerera kusokoneza kuli kwakukulu, ayenera kukanikiza mkati ndi kukanikiza. Kaya yagwetsedwa kapena kukanikiza mkati, kupendekeka kuyenera kupewedwa. Pambuyo posonkhanitsa, mpata wamafuta ndi dzenje lamafuta ziyenera kukhala pamalo ofunikira.

Pa ma bearing ofooka atasonkhana, 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 oyenera ndi shaft mkati mwa mulingo wololera. Pofuna kupewa kuti shaft sleeve isazungulire panthawi yogwira ntchito, ma pini oyika kapena zomangira zopingasa zimayikidwa pamwamba pa malo olumikizirana pakati pa shaft sleeve ndi housing. Chifukwa cha kuuma kosiyana kwa thupi la bokosi ndi zida za shaft sleeve, pobowola, zimakhala zosavuta kuti drill bit itsamire kumbali yofewa ya zinthu. Mayankho ake ndi awa: choyamba, gwiritsani ntchito kubowola chitsanzo kuti mubowole dzenje kumbali yolimba ya zinthu musanabowole; chachiwiri, gwiritsani ntchito drill bit yayifupi kuti muwonjezere kulimba kwa drill bit pobowola.

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.

● Kupanga chitsamba chonyamula katundu 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.

● 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.

● Kukwapula kwa zipolopolo zonyamula katundu

Pa zipolopolo zogawanika, malo opukutira shaft ofanana amagwiritsidwa ntchito. Nthawi zambiri, chipolopolo chonyamulira chimachotsedwa kaye, kenako chipolopolo chapamwamba chimachotsedwa. Kuti ziwongolere kugwira ntchito bwino, 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 kukuwonjezeka. Chivundikiro chonyamulira chikakamizidwa, shaft imatha kuzungulira momasuka popanda kuonekera bwino, ndipo malo olumikizirana akukwaniritsa zofunikira, kukwawa kumamalizidwa.

● Kuyeza kwa chilolezo chonyamula katundu

Kukula kwa malo operekera zitsulo kungasinthidwe ndi gasket pakati pa mtunda kapena pokanda mwachindunji chitsamba choperekera zitsulo. Malo operekera zitsulo nthawi zambiri amayesedwa pogwiritsa ntchito njira yokanikiza zitsulo. Tengani magawo angapo a waya wotsogolera ndi mainchesi akulu kuposa malo operekera zitsulo ndikuziyika pa journal ndi pamwamba pa malo operekera zitsulo. Kenako limbitsani nati kuti mukanikize bwino malo operekera zitsulo pakati, masulani nati, chotsani chivundikiro cha zitsulo, ndikuchotsa mosamala waya wotsogolera wophwanyika. Gwiritsani ntchito micrometer kuti muyese makulidwe a gawo lililonse lomwe latengedwa. Kutengera makulidwe apakati a waya wotsogolera, malo operekera zitsulo amatha kudziwika. Malo operekera zitsulo ayenera kukhala 1.5-2.5 mm (mm) ya mainchesi a shaft. Pamene mainchesi ali akulu, malo operekera zitsulo ayenera kutengedwa. Ngati mainchesi a shaft ndi 60mm, malo operekera zitsulo ayenera kukhala pakati pa 0.09 ndi 0.15mm.

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 olembedwa 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 chogwiriracho chasonkhanitsidwa pa shaft ndi m'dzenje la nyumba, sipayenera kukhala chopindika.

Pakati pa mabearing awiri omwe ali pa mzere womwewo, munthu ayenera kuyambitsa shaft kusuntha pamene shaft ikukula motentha.

Pomanga 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℃.
