Nkhani za Kampani

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 kupopera mchere. Kulimba kwambiri kwa mndandanda wa 4 ndi koyenera Maberamu a MpiraUlusi wa kaboni umakwaniritsa zofunikira zopepuka kwambiri komanso zamphamvu kwambiri. Nkhaniyi ikufotokoza bwino zinthu zisanu zazikulu zomwe zimagwiritsidwa ntchito popanga shaft kuti zikuthandizeni kukwaniritsa zosowa zanu za polojekiti.

Mukayamba kufufuza zinsinsi za Kunyamula mzeres, mungapeze 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. Mukakhala 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.

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 dziko la makina, ma thrust bearing ndi zinthu zofunika kwambiri zomwe zimaonetsetsa kuti ntchito ikuyenda bwino komanso kulimbikitsa kupita patsogolo kolondola kwambiri m'makampani. Amatumiza mphamvu ya axial kudzera mu zinthu zozungulira ndipo, ndi mapangidwe osiyanasiyana monga mipira, ma rollers ndi ma needle rollers, amagwiritsidwa ntchito mu ma transmissions a magalimoto, machitidwe oyendetsa sitima zapamadzi ndi injini za aero, kuthandizira chitukuko chabwino cha mafakitale osiyanasiyana ndi magwiridwe ake apadera.

Kusiyana kwakukulu pakati pa ma bearing a mpira ndi ma roller bearing ndi mawonekedwe ndi momwe chinthu chogudubuza chimagwirira ntchito, zomwe zimakhudza mwachindunji magwiridwe antchito awo ndi momwe amagwiritsidwira ntchito.

Nthawi zina timalandira ndemanga kuchokera kwa makasitomala za momwe ma bearing ayenera kusamalidwa ndi kukonzedwa. Kotero lero tiyeni tikambirane za kukonza ndi kusamalira ma bearing.

Ma bearings a mitundu yosiyanasiyana amagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana amafakitale chifukwa cha mawonekedwe awo komanso kusiyana kwa magwiridwe antchito.
