Bearing bushing, chinthu chofunikira kwambiri pamakina, kwenikweni ndi bushing yomwe imayikidwa pa shaft. Ntchito yake yayikulu ndikuthandiza shaft ndikuchepetsa kwambiri coefficient of friction. Amapangidwa makamaka ndi chitsulo ndipo amatha kusinthana ndi malo ovuta monga kutentha kwambiri, kuthamanga kwambiri, liwiro lalikulu komanso kulondola kwambiri. Bearing bushing sikuti imangochepetsa malo olumikizirana pakati pa shaft ndi chitsulo chakunja, motero imachepetsa kuwonongeka kwa shaft, komanso imakulitsa kwambiri moyo wa shaft. Kuphatikiza apo, pali mitundu yosiyanasiyana ya bearing bushing.

The Kutengera kwa Turntable Nyumba ndi mtundu wa nyumba yayikulu komanso yayikulu kwambiri yokhala ndi kapangidwe kapadera komwe kamatha kupirira katundu wambiri. Ili ndi kapangidwe kakang'ono, kuzungulira kosavuta, komanso kuyika ndi kukonza kosavuta. Kumene kuli mabearing, payenera kukhala malo othandizira. Malo othandizira amkati mwa bearing ndi shaft, ndipo chithandizo chakunja ndi chomwe chimadziwika kuti bearing housing.

Ubwino ndi kuipa kwa singano chozungulira maberiya

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.

Mabearing ndi zida zomwe zimagwiritsidwa ntchito kwambiri mu zida zamakanika. Ntchito yawo yayikulu ndikuthandiza magawo ozungulira a makina, kuchepetsa kuchuluka kwa kukangana panthawi yoyenda, ndikuwonetsetsa kuti akuzungulira molondola. Njira yodziwira kuyika mabearing kumbuyo ndiyofunikira kwambiri pakugwiritsa ntchito bwino komanso kusamalira mabearing. Zotsatirazi zipereka chiyambi chatsatanetsatane cha njira zodziwira kuyika koyenera komanso kobwerera m'mbuyo kwa mabearing.

Maberiyani ozungulira a cylindrical, monga zigawo zazikulu za makina, amadalira kukonza bwino nthawi yawo yonse komanso magwiridwe antchito awo. Njira zotsatirazi zosamalira zimachitika pang'onopang'ono kutengera miyezo yamakampani, kuphatikizapo kukonzekera kusokoneza, kuyeretsa ndi kuyang'anira, kukhazikitsa mafuta, ndi kuyang'anira pambuyo pake kuti zitsimikizire kuti maberiyani akugwira ntchito bwino panthawi yovuta yogwira ntchito.

Mu kupanga mafakitale ndi ntchito zamakina, ma bearing, monga zigawo zazikulu, amagwirizana mwachindunji ndi kukhazikika ndi moyo wautumiki wa zida. Ngati mtundu wa ma bearing suli wofanana ndi muyezo, sizingokhudza momwe zida zimagwirira ntchito, komanso zingayambitse kutayika kwachuma monga kuyimitsidwa kwa ntchito ndi kukonza. Ndiye, kodi munthu angadziwe bwanji mtundu wa bearing? Mu nkhani ya lero, tiyeni tikambirane mwadongosolo.

Shaft yolimba ya aluminiyamu yopangidwa ndi anodized ndi yopepuka komanso yosagwira dzimbiri. Chitsulo chosapanga dzimbiri cha mndandanda wa 3 chili ndi kukana bwino kwa mchere. Kulimba kwamtundu wa 4 ndi koyenera kugwiritsa ntchito ma bearing a mpira. Ulusi wa kaboni umakwaniritsa zofunikira zopepuka komanso zamphamvu kwambiri. Nkhaniyi ikufotokoza bwino za zinthu zisanu zazikulu za shaft kuti ikuthandizeni kukwaniritsa zosowa zanu za polojekiti.

Mukayamba kufufuza zinsinsi za ma bearing a linear, mutha kupeza kuti opanga osiyanasiyana amapereka mitundu yosiyanasiyana ya zinthu za shaft. Zipangizo za mitundu yosiyanasiyana ya ma bearing zimaphatikizapo ma shaft olimba a aluminiyamu, ma shaft achitsulo olimba pamwamba, zinthu zosiyanasiyana zosapanga dzimbiri, ndi ulusi wa carbon, ndi zina zotero. Mukayang'anizana ndi zosankha zambiri, mungasokonezeke: Kodi muyenera kuyamba bwanji kusankha mukayamba ntchito yatsopano? Musadandaule. Nkhaniyi ikupatsani kusanthula mwatsatanetsatane kwa mawonekedwe a chinthu chilichonse cha shaft ndikukupatsani chitsogozo chosankha mwachidule komanso momveka bwino.

Nthawi yomweyo, tidzatchulanso momwe mungagwiritsire ntchito ma bearing a mpira mosavuta pa zipangizo za shaft izi kuti mukwaniritse zosowa zanu zosiyanasiyana mu polojekitiyi.

Choyamba, tiyeni tiwone mozama mawonekedwe apadera a shaft yolimba ya aluminiyamu (6060-T66).

Maberiyani a Ceramic ndi otetezedwa ku dzimbiri, otetezedwa ku kutentha komanso opepuka, zomwe zimapangitsa kuti akhale oyenera malo ovuta kwambiri. Maberiyani achitsulo chosapanga dzimbiri ali ndi mphamvu yolimba komanso mtengo wotsika, ndipo ndi oyenera kugwiritsidwa ntchito nthawi zonse. Sankhani kutengera momwe zimagwiritsidwira ntchito kuti muwongolere magwiridwe antchito ndi moyo wa chipangizocho.

Mu zida zamakina, kusankha ma bearing kumakhudza mwachindunji magwiridwe antchito ndi moyo wa ntchito ya zidazo. Ma bearing a ceramic ndi ma bearing achitsulo chosapanga dzimbiri, monga mitundu iwiri yodziwika bwino, iliyonse ili ndi makhalidwe osiyana. Kumvetsetsa zabwino ndi zoyipa zawo kumathandiza popanga zisankho zoyenera pazochitika zosiyanasiyana zogwiritsira ntchito.

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 zigawo zomwe zimagwiritsidwa ntchito pothandizira komanso zigawo zomwe zimagwiritsidwa ntchito pothandizira kuzungulira kwa ma shaft. Ma bearing amatha kugawidwa malinga ndi momwe amagwirira ntchito m'ma bearing otsetsereka ndi ma rolling bearing. Malinga ndi momwe katundu wawo umayendera, pali ma radial bearing, ma thrust bearing, ndi ma radial thrust bearing, ndi zina zotero.
