Pali mitundu yambiri ya mayendedwe, ndipo zotengera zomwe ziyenera kugwiritsidwa ntchito pazida zosiyanasiyana, liwiro komanso kulondola ndizosiyana.Mitundu ya zitsulo zimayikidwa molingana ndi kukula kwa mayendedwe ogubuduza: mayendedwe ang'onoang'ono, mayendedwe ang'onoang'ono, apakati ndi ang'onoang'ono, apakati ndi akuluakulu amtundu, ma bere akuluakulu, owonjezera akuluakulu.Zimbalangondo zimagawidwa kukhala zonyamula mpira ndi zodzigudubuza malinga ndi mitundu ya zinthu zogubuduza.
Pakati pawo, mayendedwe odzigudubuza amagawidwa kukhala: mayendedwe a cylindrical wodzigudubuza, mayendedwe a singano, ma tepi odzigudubuza, ndi zozungulira zozungulira malinga ndi mtundu wa odzigudubuza.Ma bearings amatha kugawidwa m'mabere odzipangira okha komanso osagwirizanitsa malinga ndi momwe amadzipangira okha panthawi ya ntchito.
Ma bearings amagawidwa molingana ndi mtundu wa mawonekedwe ogubuduza: ma radial bearings, thrust bearings, axial contact bearings, ndi mayendedwe amakona olumikizana.
Ndiye ndi mitundu yanji yatsatanetsatane ya ma bere?Tsopano tiyeni tiphunzire pamodzi
1. Kodi mumadziwa bwanji za ma berelo odutsa?
Zodzigudubuza za ma cylindrical roller bearings nthawi zambiri zimayendetsedwa ndi nthiti ziwiri za mphete imodzi.Odzigudubuza khola ndi mphete yowongolera amapanga kuphatikiza, komwe kumatha kupatulidwa ndi mphete ina yonyamula, yomwe imakhala yolekanitsa.
Mtundu woterewu ndi wosavuta kukhazikitsa ndi kusokoneza, makamaka pamene mphete zamkati ndi zakunja zimafunika kuti zikhale ndi kusokoneza koyenera ndi shaft ndi nyumba.Mtundu woterewu nthawi zambiri umangogwiritsidwa ntchito kunyamula katundu wa radial, mzere umodzi wokha wokhala ndi nthiti pa mphete zamkati ndi zakunja zimatha kunyamula katundu wochepa wokhazikika wa axial kapena katundu wambiri wapakati wa axial.
Malo ogwiritsira ntchito: ma motors akulu, masipingo a zida zamakina, mabokosi a axle, ma crankshafts a injini ya dizilo, magalimoto, ma gearbox omwe amakumbukira, ndi zina zambiri.
2. Tapered wodzigudubuza mayendedwe
Mtundu woterewu uli ndi ma rollers a truncated truncated, omwe amatsogoleredwa ndi nthiti yaikulu ya mphete yamkati.Kapangidwe kameneka kamapangitsa ma vertices a mawonekedwe a conical amkati mwa mphete yamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wakunja, njira yakunja yamphete komanso chodzigudubuza chozungulira chiwoloka pakati pa chimbalangondo.mfundo pamwamba.Mizere ya mzere umodzi imatha kunyamula katundu wa radial ndi njira imodzi ya axial, pamene mizere iwiri ya mizere imatha kunyamula katundu wa radial ndi njira ziwiri za axial, ndipo amagwiritsidwa ntchito makamaka kunyamula katundu wolemera ndi katundu wokhudzidwa.
Mapulogalamu: Magalimoto: Mawilo akutsogolo, mawilo akumbuyo, ma transmissions, ma pinion shafts.Makina opangira zida zamakina, makina omanga, makina akulu aulimi, zida zochepetsera zida zamagalimoto a njanji, makosi opukusa mphero ndi zida zochepetsera.
Chachinayi, cholumikizira olowa
Chipinda chozungulira chozungulira ndi mtundu wamtundu wopindika.Malo ake ogubuduza ndi opindika mkati ndi kunja kopindika.Ikhozanso kuzungulira ndi kugwedeza mbali iliyonse panthawi yolimbitsa thupi.Zapangidwa ndi njira zosiyanasiyana zopangira.Chigwirizano cha mafupa chimakhala ndi mphamvu zonyamula katundu waukulu, kukana kukhudzidwa, kukana kwa dzimbiri, kukana kuvala, kudzigwirizanitsa, ndi mafuta abwino.
Mipira isanu, yolumikizana ndi mfundo zinayi
Itha kunyamula katundu wa radial ndi bidirectional axial load.Chidutswa chimodzi chingathe m'malo mwa mpira wolumikizana ndi wolumikizana kutsogolo kapena kuphatikiza kumbuyo, ndipo ndichoyenera kunyamula katundu wa axial kapena katundu wamagulu okhala ndi zigawo zazikulu za axial katundu.Mtundu woterewu ukhoza kunyamula chilichonse mwa ma angles okhudzana nawo akhoza kupangidwa pamene katundu wa axial ali mbali iliyonse, kotero kuti ferrule ndi mpira nthawi zonse zimakhala zogwirizana ndi mbali ziwiri ndi mipeni itatu pa mzere uliwonse.
Malo ogwiritsira ntchito: injini za jet ndege, makina opangira gasi.
6. Kukankha cylindrical wodzigudubuza mayendedwe
Zimapangidwa ndi mphete zojambulira zowoneka ngati ma washer (ma shaft ochapira, ochapira mipando), ma roller ozungulira ndi ma cage.Ma cylindrical rollers amapangidwa ndikukonzedwa ndi malo owoneka bwino, kotero kugawa kwapakati pakati pa odzigudubuza ndi malo othamanga kumakhala kofanana, ndipo kumatha kunyamula katundu wamtundu umodzi wa axial, wokhala ndi mphamvu yayikulu ya axial ndi kulimba kwa axial.
Malo ogwiritsira ntchito: makina obowola mafuta, makina achitsulo ndi zitsulo.
7. Kukankha singano wodzigudubuza mayendedwe
Zimbalangondo zolekanitsa zimakhala ndi mphete zojambulira, zodzigudubuza za singano ndi zomangira za khola, ndipo zimatha kuphatikizidwa mosasamala ndi mphete zoonda zapamsewu kapena mphete zodulidwa ndi makina okhuthala.Zimbalangondo zosalekanitsidwa ndi mayendedwe ophatikizika omwe amapangidwa ndi mphete zodinda bwino, zodzigudubuza za singano ndi zomangira za khola, zomwe zimatha kunyamula katundu wa unidirectional axial.Zonyamula zoterezi zimakhala ndi malo ochepa ndipo zimakhala zopindulitsa pamapangidwe opangidwa ndi makina.Ambiri a iwo amangogwiritsa ntchito masingano a singano ndi khola, ndipo amagwiritsa ntchito malo osonkhanitsira patsinde ndi nyumba ngati malo othamanga.
Malo ogwiritsira ntchito: zida zosinthira liwiro zamagalimoto, olima, zida zamakina, ndi zina.
Zisanu ndi zitatu, zopindika zopindika
Mtundu uwu wa kunyamula uli ndi truncated truncated wodzigudubuza (mapeto aakulu ndi ozungulira pamwamba), ndi wodzigudubuza molondola motsogozedwa ndi nthiti ya raceway mphete (shaft washer, mpando washer), ndipo anapangidwa kuti mpikisano pamwamba. washer wa shaft ndi mphete ya mpando ndi odzigudubuza Pamwamba pamtundu uliwonse wa conical padziko lapansi umadutsa pamtunda wapakati pa mzere wonyamula, njira imodzi yokha imatha kunyamula katundu wa axial wa njira imodzi, ndi ziwiri- njira yonyamula imatha kunyamula katundu wanjira ziwiri.
Munda wogwiritsira ntchito Njira imodzi: mbedza ya crane, chowotcha mafuta.Njira ziwiri: kugudubuza mphero khosi.
Zisanu ndi zinayi, zolondola kwambiri, zolimba kwambiri, zolemetsa kwambiri, zothamanga kwambiri
Matebulo a rotary ali ndi mphamvu yonyamula ma axial ndi ma radial, kuuma kopendekeka kwambiri komanso kulondola kwambiri, ndipo ndi oyenera kunyamula makonzedwe pamatebulo ozungulira komanso muyeso ndi kuyesa.Mukayika mtundu uwu wa kunyamula, ndikofunikira kuwongolera torque yomangika ya zomangira zomangira.
10. Slewing kubala ndi sanali muyezo mwamakonda
Kunyamula slewing kumatha kunyamula katundu wamkulu wa radial, axial katundu ndi mphindi yogubuduza ndi katundu wina wokwanira nthawi yomweyo.Zimagwirizanitsa ntchito zosiyanasiyana monga kuthandizira, kuzungulira, kutumiza, ndi kukonza.Nthawi zokhala ndi liwiro lotsika kwambiri, monga makina onyamulira, zofukula, matebulo ozungulira, makina opangira mphepo, zowonera zakuthambo ndi ma tank turrets, amagwiritsidwa ntchito kwambiri.
Kuchuluka kwa mayendedwe ndi makonda a mayendedwe osagwirizana ndi omwe akupezeka kuti athandizire makasitomala pakuyesa ndi kupanga misa.
