Zikafika pamitundu yama bere, aliyense atha kunena kuti ndi mitundu yanji ya ma bearings omwe amagwiritsidwa ntchito?Lero, tiyeni tikutengereni kuti mudziwe mawonekedwe amitundu yosiyanasiyana ndi magawo awo ogwiritsira ntchito.
Ma bearings amagawidwa kukhala ma fani a radial ndi ma thrust fani kutengera komwe amalowera kapena ngodya yolumikizirana mwadzina.
Malingana ndi mtundu wa chinthu chogubuduza, chimagawidwa kukhala mpira ndi wodzigudubuza.
Itha kugawidwa m'magulu odziyimira pawokha komanso osadziyimira pawokha (okhazikika) molingana ndi momwe angakhalire wokhazikika.
Malingana ndi chiwerengero cha mizati ya chinthu chogubuduza, chimagawidwa kukhala mzere umodzi, wokhala ndi mizere iwiri ndi mizere yambiri.
Malingana ndi ngati zigawozo zikhoza kulekanitsidwa, zimagawidwa kukhala mayendedwe olekanitsidwa ndi mayendedwe osalekanitsidwa.
Kuphatikiza apo, pali magulu malinga ndi mawonekedwe ndi kukula kwake.
1. Angular kukhudzana mpira
Pali ma angles olumikizana pakati pa ferrule ndi mpira.The muyezo kukhudzana ngodya ndi 15 °, 30 ° ndi 40 °.Kukula kwa ngodya yolumikizana, ndikokulirapo kwa mphamvu ya axial.Kuchepa kwa ngodya yolumikizana, kumapangitsanso kusinthasintha kothamanga kwambiri.Mzere umodzi wonyamula ukhoza kupirira katundu wa radial ndi unidirectional axial load.Mizere iwiri imodzi yokha yolumikizana ndi mpira, yomwe imaphatikizidwa kumbuyo, imagawana mphete yamkati ndi mphete yakunja, ndipo imatha kupirira katundu wa radial ndi bidirectional axial load.
Angular kukhudzana kwa mpira
Cholinga chachikulu:
Mzere umodzi: spindle chida cha makina, mota yothamanga kwambiri, turbine yamagetsi, cholekanitsa chapakati, gudumu lakutsogolo lagalimoto yaying'ono, pinion shaft yosiyana.
Mizere iwiri: pampu yamafuta, chowuzira mizu, kompresa ya mpweya, ma transmission osiyanasiyana, pampu ya jakisoni wamafuta, makina osindikizira.
2, Kudzigwirizanitsa ndi mpira
Mipira yachitsulo yamizere iwiri, msewu wakunja wa mphete ndi wamtundu wamkati wozungulira, kotero umatha kusintha kusintha kolakwika kwa axis chifukwa cha kupatuka kapena kusakhazikika kwa shaft kapena nyumba.Bowo lokhala ndi tapered limatha kuyikidwa mosavuta pa shaft pogwiritsa ntchito zomangira, makamaka zonyamula ma radial.
Kunyamula mpira
Ntchito zazikuluzikulu: makina opangira matabwa, shaft yotumizira makina opangira nsalu, yoyima yodzigwirizanitsa ndi mpando.
3, Self aligning wodzigudubuza kubala
Mtundu woterewu uli ndi zodzigudubuza zozungulira pakati pa mphete yakunja ya msewu wozungulira komanso mphete yamkati yanjira yapawiri.Malingana ndi mapangidwe osiyanasiyana amkati, amagawidwa m'mitundu inayi: R, Rh, RHA ndi Sr. chifukwa arc pakati pa msewu wakunja wa mphete imagwirizana ndi malo oberekera, imakhala ndi ntchito yokhazikika, kotero imatha kusintha kusokonezeka kwa axis chifukwa cha kupotoza kapena kusayenda bwino kwa shaft kapena chipolopolo chakunja, ndipo imatha kunyamula katundu wa radial ndi bidirectional axial load.
Zovala za Spherical Roller
Ntchito zazikulu: makina amapepala, chochepetsera, chitsulo cha njanji, mpando wa gearbox wogubuduza, njanji ya mphero, chopondapo, chotchinga chonjenjemera, makina osindikizira, makina opangira matabwa, zochepetsera zosiyanasiyana zamafakitale, zodziyimira zokha zokha ndi mpando.
4. Kukankhira wodzigudubuza wodzigudubuza kubala
Mu mtundu uwu wa kunyamula, odzigudubuza ozungulira amapangidwa mozungulira.Chifukwa msewu wa mpikisanowu ndi wozungulira ndipo umakhala ndi magwiridwe antchito apakatikati, shaft imatha kuloledwa kukhala ndi zokonda zingapo.Mphamvu ya axial katundu ndi yayikulu kwambiri.Imatha kunyamula ma radial angapo ponyamula katundu wa axial.Kupaka mafuta nthawi zambiri kumagwiritsidwa ntchito.
kukankhira wodzigudubuza wodzigudubuza
Ntchito zazikulu: jenereta wa hydraulic, vertical motor, shaft propeller ya zombo, chochepetsera chopukutira zitsulo zopukutira zitsulo, crane tower, mphero yamakala, extruder ndi kupanga makina.
5. Tapered wodzigudubuza kubereka
Kunyamula kotereku kumakhala ndi chodzigudubuza chooneka ngati cone, chomwe chimayendetsedwa ndi flange yayikulu ya mphete yamkati.M'mapangidwe, nsonga yamkati mwa mphete yamtundu wamtundu wamtundu, mawonekedwe akunja a mphete ndi mawonekedwe opindika amtundu wodzigudubuza amadutsana pamlingo wapakati.Mzere umodzi wonyamula katundu ukhoza kunyamula katundu wa radial ndi njira imodzi ya axial katundu, ndipo mizere iwiri yonyamula mizere imatha kunyamula katundu wa radial ndi njira ziwiri za axial katundu, zomwe zimakhala zoyenera kunyamula katundu wolemera ndi katundu wokhudzidwa.
Tapered wodzigudubuza wonyamula
Ntchito zazikulu: Galimoto: gudumu lakutsogolo, gudumu lakumbuyo, kufalitsa, kusiyanitsa kwa pinion shaft.Makina opangira zida zamakina, makina omanga, makina akulu aulimi, makina ochepetsera magalimoto a njanji, khosi lopukutira mphero ndi chochepetsera.
6, Kuzama kwa mpira wozama
Mwamadongosolo, mphete iliyonse ya mpira wakuya wa groove ili ndi msewu wopitilira muyeso wokhala ndi gawo limodzi mwamagawo atatu a circumference ya equatorial bwalo la mpirawo.Mpira wozama wa groove umagwiritsidwa ntchito makamaka kunyamula katundu wa radial, komanso amatha kunyamula katundu wina wa axial.
Pamene chiwongolero cha radial chiwongolero chikuwonjezeka, chimakhala ndi mphamvu yolumikizana ndi mpira ndipo imatha kunyamula katundu wosinthasintha wa axial mbali ziwiri.Poyerekeza ndi mitundu ina ya mayendedwe omwe ali ndi kukula kofanana, mtundu uwu wa kunyamula uli ndi coefficient yaing'ono yotsutsana, kuthamanga kwa malire ndi kulondola kwambiri.Ndilo mtundu wamtundu womwe umasankhidwa kuti ogwiritsa ntchito asankhe.
Mpira wakuya wakuya
Ntchito zazikulu: magalimoto, thirakitala, zida zamakina, mota, mpope wamadzi, makina aulimi, makina opangira nsalu, etc.
7. Kuthamanga kwa mpira
Zimapangidwa ndi mphete yojambulira ngati washer yokhala ndi msewu wothamanga, mpira ndi msonkhano wa khola.Mphete yothamanga yomwe imagwirizanitsidwa ndi shaft imatchedwa mphete ya shaft, ndipo mphete yothamanga yofanana ndi nyumbayo imatchedwa mphete ya mpando.Njira ziwirizi zimagwirizana ndi mphete yapakati ndi shaft yobisika.Njira imodzi imatha kunyamula katundu wa axial wa njira imodzi, ndipo njira ziwiri zimatha kunyamula katundu wa axial wanjira ziwiri (ngakhalenso sungathe kunyamula katundu wa radial).
Kuthamanga kwa mpira
Kugwiritsa ntchito kwakukulu: pini yowongolera galimoto, makina opangira zida.
8, Kuthamangitsa wodzigudubuza kubala
The thrust roller bearing imagwiritsidwa ntchito kunyamula tsinde ndi axial katundu ngati katundu wamkulu, ndipo katundu wautali sayenera kupitirira 55% ya katundu wa axial.Poyerekeza ndi mayendedwe ena odzigudubuza, kunyamula kotereku kumakhala ndi ma coefficient otsika, kuthamanga kwambiri komanso kudzigwirizanitsa.Wodzigudubuza wa 29000 wonyamula ndi asymmetric spherical roller, yomwe ingachepetse kutsetsereka kwa ndodo ndi mpikisano wothamanga pa ntchito.Komanso, wodzigudubuza ndi yaitali ndi lalikulu m'mimba mwake, ndi ambiri odzigudubuza ndi lalikulu katundu mphamvu.Nthawi zambiri amapaka mafuta, ndipo mafuta amatha kugwiritsidwa ntchito pakanthawi kochepa.
Chovala chodzigudubuza
Ntchito zazikulu: jenereta ya hydraulic, mbedza ya crane.
9, Cylindrical wodzigudubuza kubereka
Wodzigudubuza wa cylindrical roller bearing nthawi zambiri amatsogoleredwa ndi mbali ziwiri za mphete yonyamula.Chodzigudubuza khola ndi mphete yolondolera zimapanga msonkhano, womwe ukhoza kupatulidwa ndi mphete ina yonyamula.Ndi ya chimbalangondo cholekanitsidwa.
Kubereka ndikosavuta kukhazikitsa ndi kusokoneza, makamaka pamene mphete zamkati ndi zakunja zimafunika kuti zisokonezedwe ndi shaft ndi nyumba.Mtundu woterewu nthawi zambiri umagwiritsidwa ntchito ponyamula katundu wa radial.Mzere umodzi wokha wokhala ndi mphete zamkati ndi zakunja zokhala ndi m'mphepete mwake ungathe kunyamula katundu wocheperako wokhazikika wa axial kapena katundu wamkulu wapakatikati.
Zovala za cylindrical roller
Ntchito zazikulu: ma motors akulu, masipiko a zida zamakina, mabokosi a axle, ma crankshafts a injini ya dizilo, magalimoto, mabokosi osinthira, ndi zina zambiri.
