Ma bearings ndi zinthu zofunika kwambiri pazida zamakina. Ntchito yake yayikulu ndikuthandizira makina ozungulira thupi kuti achepetse kugundana kwamphamvu yamakina panthawi yotumizira zida.
Ma bearings amagawidwa kukhala ma radial bearings ndi ma thrust bears motengera mayendedwe osiyanasiyana onyamula katundu kapena ngodya zolumikizirana mwadzina.
Malinga ndi mtundu wa zinthu zogubuduza, zimagawidwa kukhala: mayendedwe a mpira ndi mayendedwe odzigudubuza.
Malingana ndi momwe angagwirizanitsire, amagawidwa kukhala: mayendedwe odzipangira okha ndi osagwirizana (olimba).
Malingana ndi chiwerengero cha mizere ya zinthu zogubuduza, iwo amagawidwa kukhala: mayendedwe a mzere umodzi, mizere iwiri, ndi mizere yambiri.
Malingana ndi ngati zigawozo zikhoza kulekanitsidwa, zimagawidwa kukhala: mayendedwe olekanitsidwa ndi osagwirizana.
Palinso magulu otengera mawonekedwe ndi kukula kwake.
Nkhaniyi imagawana makamaka mawonekedwe, kusiyana ndi kugwiritsiridwa ntchito kofanana kwa 14 mayendedwe wamba.
8 Kuwombera mpira
Mapiritsi a thrust roller amagwiritsidwa ntchito pazitsulo zomwe zimanyamula katundu wambiri wa axial ndi katundu wosakanikirana, koma meridional katundu sayenera kupitirira 55% ya katundu wa axial. Poyerekeza ndi mayendedwe ena odzigudubuza, kunyamula kotereku kumakhala ndi kugundana kocheperako, kuthamanga kwambiri kozungulira, ndipo kumatha kusintha. Zodzigudubuza za 29000 zokhala ndi ma asymmetric spherical rollers, omwe amatha kuchepetsa kutsetsereka pakati pa ndodo ndi msewu wothamanga pakugwira ntchito. Zodzigudubuza ndi zazitali ndipo zili ndi mainchesi akulu. Amakhala ndi ma rollers ambiri komanso katundu wambiri. Nthawi zambiri amapaka mafuta. Kupaka mafuta kungagwiritsidwe ntchito pa liwiro lotsika.
Ntchito zazikulu: majenereta a hydraulic, mbedza za crane.
9 Cylindrical Roller Bearings
Zodzigudubuza za ma cylindrical roller bearings nthawi zambiri zimayendetsedwa ndi nthiti ziwiri za mphete yonyamula. Chodzigudubuza cha khola ndi mphete yolondolera zimapanga msonkhano womwe ungathe kulekanitsidwa ndi mphete ina yonyamula ndipo ndi mayendedwe olekanitsidwa.
Mtundu woterewu ndi wosavuta kukhazikitsa ndi kusokoneza, makamaka pamene kusokoneza kuli pakati pa mphete zamkati ndi zakunja, shaft ndi chipolopolo chimafunika. Mtundu woterewu nthawi zambiri umagwiritsidwa ntchito ponyamula katundu wa radial. Mizere ya mzere umodzi wokha wokhala ndi nthiti pa mphete zamkati ndi zakunja zimatha kunyamula katundu wochepa wokhazikika wa axial kapena katundu wamkulu wapakati wa axial.
Kugwiritsa ntchito kwakukulu: ma motors akulu, masipiko a zida zamakina, mabokosi a axle, ma crankshafts a injini ya dizilo, magalimoto, mabokosi otumizira okhala ndi mayendedwe, ndi zina zambiri.
10 Mfundo zinayi zolumikizana ndi mpira
Imatha kunyamula katundu wa radial ndi bidirectional axial load. Chovala chimodzi chimatha kulowa m'malo mwa mpira wolumikizana ndi wolumikizana kutsogolo kapena kuphatikiza kumbuyo. Ndizoyenera kunyamula katundu wa axial kapena katundu wopangidwa ndi gawo lalikulu la axial katundu. Mtundu woterewu ukhoza kupirira njira iliyonse. Mmodzi wa kukhudzana ngodya akhoza kupangidwa pamene pali axial katundu, kotero ferrule ndi mpira nthawi zonse kukhudzana ndi mfundo zitatu mbali zonse za mzere kukhudzana.
Ntchito zazikuluzikulu: injini zandege, makina opangira gasi.
11 Gwirani ma cylindrical roller bearings
Zimapangidwa ndi mphete yojambulira ngati washer (mphete ya shaft, mphete yapampando) ndi cylindrical roller ndi zida za khola. Wodzigudubuza wa cylindrical amatengera ma convex pamwamba pokonza, kotero kuthamanga pakati pa chogudubuza ndi malo othamanga kumagawidwa mofanana, ndipo kumatha kupirira njira imodzi ya axial. Ili ndi mphamvu yayikulu ya axial komanso kulimba kwa axial.
Ntchito zazikulu: zopangira mafuta, makina opangira chitsulo ndi zitsulo.
12 Phunzirani singano yodzigudubuza
Zimbalangondo zolekanitsidwa zimakhala ndi mphete zanjira yothamanga, zodzigudubuza za singano ndi zomangira khola, ndipo zimatha kuphatikizidwa mosasamala ndi mphete zoonda zopindika kapena mphete zodulidwa zokhuthala. Ma fani osasiyanitsidwa ndi ma fani ophatikizika omwe amapangidwa ndi mphete zodinda bwino, zodzigudubuza za singano ndi zomangira khola. Iwo amatha kupirira unidirectional axial katundu. Mtundu woterewu umatenga malo ochepa ndipo umathandizira kupanga makina ophatikizika. Ambiri a iwo okha wodzigudubuza singano ndi khola msonkhano ntchito, ndi okwera pamwamba kutsinde ndi nyumba ntchito ngati mpikisano pamwamba.
Ntchito zazikulu: zida zotumizira zamagalimoto, olima, zida zamakina, ndi zina.
13 Mapiritsi a ma tapered odzigudubuza
Mtundu woterewu umakhala ndi zodzigudubuza zooneka ngati cone (mapeto akulu ndi ozungulira). Odzigudubuza amatsogoleredwa molondola ndi nthiti za mphete yothamanga (mphete ya shaft, mphete ya mpando). Mapangidwewa amatsimikizira kuti malo othamanga a mphete ya shaft ndi mphete ya mpando ndi kupukuta pamwamba pa odzigudubuza Pamwamba pamtundu uliwonse wa conical umadutsa pamtunda wapakati pa mzere wonyamula. Ma mayendedwe anjira imodzi amatha kunyamula katundu wanjira imodzi, ndipo njira ziwiri zimatha kunyamula katundu wanjira ziwiri.
Cholinga chachikulu:
Njira imodzi: Chingwe cha crane, chobowolera mafuta chozungulira.
Mayendedwe onse: kugudubuza mphero mpukutu khosi.
14 Ikani mpira wozungulira wokhala ndi mpando
Mpira wozungulira wokhala pansi umapangidwa ndi mpira wozungulira wokhala ndi zisindikizo mbali zonse ziwiri ndi mpando (kapena chitsulo chosindikizidwa) wokhala ndi mpando. Mapangidwe amkati a mpira wozungulira wakunja ndi wofanana ndi wakuya kwa groove mpira, koma mphete yamkati yamtunduwu ndi yotakata kuposa mphete yakunja. Mphete yakunja ili ndi malo ozungulira akunja, omwe amatha kulumikizidwa ndi malo ozungulira a concave pampando wonyamula.
Main ntchito: migodi, zitsulo, ulimi, makampani mankhwala, nsalu, kusindikiza ndi utoto, kufalitsa makina, etc.
