Sindingathe kusiyanitsa mitundu yosiyanasiyana ya mabearing Makhalidwe, kusiyana ndi momwe amagwiritsidwira ntchito mitundu 14 ya mabearing (gawo 2)
Mabearing amagawidwa m'magulu a ma radial bearing ndi Kunyamulas kutengera komwe katundu akupita kapena ngodya yolumikizirana ndi dzina.
Malinga ndi mitundu ya zinthu zozungulira, zimagawidwa m'magulu monga: mipira yoyendera ndi chozungulira maberiya.
Malinga ndi ngati zingathe kudzilungamitsa zokha, zimagawidwa m'magulu a ma bearing odzilungamitsa okha ndi ma bearing osadzilungamitsa okha (rigid bearings).
Malinga ndi kuchuluka kwa mizere ya zinthu zozungulira, zimagawidwa m'magulu awa: ma bearing a mzere umodzi, ma bearing a mzere umodzi, ndi ma bearing a mzere wambiri.
Malinga ndi ngati zigawozo zitha kulekanitsidwa, zimagawidwa m'magulu monga: ma bearing olekanitsidwa ndi ma bearing osalekanitsidwa.
Kuphatikiza apo, pali kugawa kutengera mawonekedwe ndi kukula kwa kapangidwe kake.
- Mabearing a Roller Oponderezedwa
Mabeya ozungulira othrust amagwiritsidwa ntchito pa ma shaft omwe amanyamula katundu wa axial ndi katundu wophatikizana wa radial, koma katundu wa radial sayenera kupitirira 55% ya katundu wa axial. Poyerekeza ndi mabeya ena ozungulira othrust, mtundu uwu wa bearing uli ndi coefficient yotsika ya friction, liwiro lozungulira lapamwamba, komanso luso lodzilamulira lokha. Ma rollers a 29000 type bearing ndi ma asymmetric spherical rollers, omwe amatha kuchepetsa kutsetsereka pakati pa ma rollers ndi raceways panthawi yogwira ntchito. Ma rollers ndi aatali, ali ndi mainchesi akulu, ndipo ali ndi ma rollers ambiri okhala ndi mphamvu yayikulu yonyamula katundu. Nthawi zambiri amathiridwa mafuta, ndipo nthawi zina amathiridwa mafuta pang'ono, mafuta odzola angagwiritsidwe ntchito.
Ntchito zazikulu: Majenereta amagetsi, zingwe zolumikizira ma crane.
- Mabeya ozungulira a cylindrical
Ma rollers a cylindrical roller bearing nthawi zambiri amatsogozedwa ndi ma flanges awiri a mphete imodzi yoberekera. Chozungulira cha khola ndi mphete yotsogolera zimapanga gawo logwirizana lomwe lingathe kulekanitsidwa ndi mphete ina yoberekera, ndipo ndi la ma bereings olekanitsidwa.
Mtundu uwu wa bearing ndi wosavuta kuyika ndi kusokoneza, makamaka pamene mphete zamkati ndi zakunja zonse zikufunika kuti zigwirizane ndi shaft ndi nyumba, ubwino wake ndi wowonekera kwambiri. Mtundu uwu wa bearing nthawi zambiri umagwiritsidwa ntchito popirira katundu wa radial. Ma bearing a mzere umodzi okha omwe ali ndi ma flanges pa mphete zamkati ndi zakunja amatha kupirira katundu waung'ono wa axial kapena katundu wamkulu wa axial wosinthasintha.
Ntchito zazikulu: Ma injini akuluakulu, ma spindles a zida zamakina, mabokosi a axle a magalimoto, ma crankshafts a injini za dizilo, magalimoto, ma gearbox a ma brackets, ndi zina zotero.
- Mabeya a mpira wolumikizana ndi mfundo
Imatha kupirira katundu wozungulira komanso katundu wozungulira wa axial. Bearing imodzi imatha kusintha ma bearing a mpira wolumikizana kutsogolo kapena kumbuyo. Ndi yoyenera kunyamula katundu wozungulira wa axial kapena katundu wophatikizana wokhala ndi gawo lalikulu la katundu wozungulira. Mtundu uwu wa bearing ukakumana ndi katundu wozungulira mbali iliyonse, ngodya imodzi yolumikizirana imatha kupangidwa. Chifukwa chake, mphete ndi mipira nthawi zonse zimakhala ndi kukhudzana kwa mfundo zitatu mbali zonse ziwiri za mzere uliwonse wolumikizirana.
Ntchito zazikulu: Ma injini a ndege, ma turbine a gasi.
- Ma bereji ozungulira ozungulira
Imapangidwa ndi mphete za raceway zooneka ngati chotsukira (mphete za shaft, mphete za mipando), ma cylindrical rollers ndi ma cage assemblies. Ma cylindrical rollers amakonzedwa ndi malo ozungulira, kotero kugawa kwa kuthamanga pakati pa ma rollers ndi malo a raceway ndi kofanana. Amatha kupirira katundu wozungulira wolunjika, ali ndi mphamvu yayikulu yozungulira, komanso ali ndi kulimba kwamphamvu kwa axial.
Ntchito zazikulu: Makina obowola mafuta, makina opangira zitsulo ndi zitsulo.
- Ma beringi ozungulira singano
Maberiya olekanitsidwa amapangidwa ndi mphete za msewu wa raceway, ma needle roller ndi ma cage assemblies, ndipo amatha kuphatikizidwa momasuka ndi mphete zopyapyala za msewu wa raceway zomwe zimakonzedwa pogwiritsa ntchito stamping kapena ma raceway ang'onoang'ono omwe amakonzedwa pogwiritsa ntchito kudula. Ma beriya olekanitsidwa ndi ma beriya ofunikira omwe amapangidwa ndi mphete za msewu wa raceway zosindikizidwa bwino, ma needle roller ndi ma cage assemblies. Amatha kupirira katundu wozungulira wolunjika. Mtundu uwu wa bearing umatenga malo ochepa ndipo umakhala wothandiza pakupanga makina ochepa. Ambiri mwa iwo amangogwiritsa ntchito ma needle roller ndi ma cage assemblies, pomwe malo oyikapo shaft ndi nyumba amagwiritsidwa ntchito ngati malo a raceway.
Ntchito zazikulu: Zipangizo zosinthira liwiro la magalimoto, ma tiller, zida zamakina, ndi zina zotero.
- Ma bereji ozungulira opindika
Mtundu uwu wa bearing uli ndi ma rollers okhala ndi conical (okhala ndi malekezero ozungulira), omwe amatsogozedwa molondola ndi ma flanges a raceway rings (shaft ring, seat ring). Kapangidwe kake kamatsimikizira kuti ma vertices a conical a pamwamba pa raceway a shaft ring ndi seat ring komanso malo ozungulira a ma rollers amakumana pamalo amodzi pakati pa bearing. Ma bearing olunjika amodzi amatha kupirira katundu wa axial wolunjika umodzi, pomwe ma bearing olunjika awiri amatha kupirira katundu wa axial wolunjika mbali zonse ziwiri.
Ntchito zazikulu
Njira imodzi: Chingwe cha crane, mphete yozungulira ya chobowolera mafuta.
Kuzungulira mbali zonse ziwiri: Khosi lozungulira la mphero yozungulira yachitsulo.
- Chophimba cha mpira chozungulira chokhala ndi nyumba
Choyimirira mpira chozungulira chokhazikika chimapangidwa ndi ma bearing a mpira wozungulira wokhala ndi zisindikizo mbali zonse ziwiri ndi nyumba yonyamulira (kapena yachitsulo). Kapangidwe ka mkati ka choyimirira mpira chozungulira chozungulira ndi kofanana ndi ka choyimirira mpira chozama, koma mphete yamkati ya mtundu uwu wa choyimirira ndi yayikulu kuposa mphete yakunja. Mphete yakunja ili ndi malo akunja ozungulira ozungulira, omwe amatha kugwirizana okha ndi malo ozungulira ozungulira a nyumba yonyamulira.
Ntchito zazikulu: Migodi, zitsulo, ulimi, makampani opanga mankhwala, nsalu, utoto ndi kusindikiza. Makina onyamulira katundu, ndi zina zotero.
