Njira yosankha mtundu wa ma bearing a mota

Kusankha kwa mitundu yonyamula Mitundu yomwe imagwiritsidwa ntchito kwambiri pakugudubuza kwa ma mota ndi mayendedwe a mpira wakuya, ma cylindrical roller bearings, mayendedwe ozungulira ozungulira, ndi mayendedwe amipira olumikizana.Ma mayendedwe a malekezero onse a ma motors ang'onoang'ono amagwiritsa ntchito mayendedwe a mpira wakuya, ma mota apakati amagwiritsa ntchito mayendedwe odzigudubuza kumapeto (nthawi zambiri amagwiritsidwa ntchito ponyamula katundu wambiri), ndi mayendedwe a mpira kumapeto osanyamula (koma palinso milandu yosiyana). , monga ma motors 1050kW).Ma motors ang'onoang'ono amagwiritsanso ntchito mayendedwe ang'ono a mpira.Mapiritsi ozungulira ozungulira amagwiritsidwa ntchito makamaka pama motors akulu kapena ma mota oyimirira.Magalimoto onyamulasafuna phokoso lachilendo, kugwedezeka pang'ono, phokoso lochepa, ndi kukwera kochepa kwa kutentha.Mogwirizana ndi malamulo osankhidwa mu tebulo ili m'munsimu, zinthu zotsatirazi nthawi zambiri zimaganiziridwa kuti zifufuze njira yosankha polojekiti.Malo oyikapo chonyamulira amatha kukhala ndi kukula kwake mu malo oyikapo.Chifukwa kulimba ndi kulimba kwa shaft kumatsimikiziridwa popanga shaft system, kutalika kwa shaft nthawi zambiri kumatsimikiziridwa poyamba.Komabe, pali mitundu yosiyanasiyana ya kukula ndi mitundu ya mayendedwe ogubuduza, pomwe miyeso yoyenera kwambiri iyenera kusankhidwa.

Katundu Kukula, mayendedwe ndi chikhalidwe cha katundu wonyamula [kuchuluka kwa katundu wonyamula katundu kumasonyezedwa ndi katundu woyambira, ndipo mtengo wake ukuwonetsedwa mu tebulo la kukula kwake] Katundu wonyamulira ndi wodzaza ndi kusintha, monga kukula kwa katundu, kaya pali katundu wa radial okha, komanso ngati katundu wa axial ndi njira imodzi kapena njira ziwiri, mlingo wa kugwedezeka kapena kugwedezeka, ndi zina zotero.Mukaganizira zinthu izi, sankhani mtundu woyenera kwambiri wonyamula katundu.Nthawi zambiri, kuchuluka kwa ma radial a NSK okhala ndi mainchesi amkati omwewo amasiyanasiyana malinga ndi mndandanda, ndipo katundu woyengedwa akhoza kufufuzidwa molingana ndi chitsanzo.Mtundu wonyamulira womwe liwiro lake limatha kutengera liwiro lamakina [mtengo wocheperako womwe umawonetsedwa ndi liwiro la malire, ndipo mtengo wake ukuwonetsedwa mu tebulo la kukula kwake] Kuthamanga kwa malire sikungotengera mtundu wonyamula. , komanso amangokhala ndi kukula kwake, mtundu wa khola, ndi mlingo wolondola , zinthu zolemetsa ndi njira zopangira mafuta, ndi zina zotero, choncho, izi ziyenera kuganiziridwa posankha.Zinyamuliro zamapangidwe omwewo okhala ndi mainchesi amkati a 50 ~ 100mm ali ndi liwiro lalikulu kwambiri;kulondola kozungulira kuli ndi kulondola kozungulira kofunikira kwa mtundu wonyamula [kulondola kwa kukula ndi kulondola kwa kuzungulira kwa zotengera zatsimikiziridwa ndi GB molingana ndi mtundu wonyamula].

Kulondola kwa kubereka kumatsimikiziridwa molingana ndi chiŵerengero cha liwiro la liwiro la malire.Kukwera kolondola, kumapangitsanso kuthamanga kwa malire ndi kucheperachepera kwa kutentha.Ngati ipitilira 70% ya liwiro la malire, gawo lolondola la kunyamula liyenera kuwongolera.Pansi pa chilolezo chofanana cha radial choyambirira, chocheperako m'badwo wa kutentha, kutengera kwa mphete yamkati ndi mphete yakunja.Kuwunika kwazomwe zimayambitsa kupendekera kwa mphete yamkati ndi mphete yakunja (monga kupatuka kwa shaft chifukwa cha katundu, kusalondola bwino kwa shaft ndi nyumba) Kapena cholakwika choyika), ndikusankha mtundu wonyamula. zomwe zingagwirizane ndi chikhalidwe chautumiki ichi.Ngati kupendekera kwachibale pakati pa mphete yamkati ndi mphete yakunja ndi yayikulu kwambiri, kunyamula kudzawonongeka chifukwa cha katundu wamkati.Chifukwa chake, chonyamula chodzigudubuza chomwe chimatha kupirira malingaliro awa chiyenera kusankhidwa.Ngati kupendekerako kuli kochepa, mitundu ina ya ma bearings imatha kusankhidwa.Kusanthula njira yosankha chinthu Chotengera chosinthira shaft chimathandizidwa ndi mayendedwe awiri mumayendedwe a radial ndi axial, ndipo mbali imodzi ndi yokhazikika, yomwe imanyamula katundu wa radial ndi axial., yomwe imagwira ntchito mu kayendedwe ka axial pakati pa shaft yokhazikika ndi nyumba yonyamula.Mbali inayi ndi yaulere, yomwe imanyamula katundu wa radial yokha ndipo imatha kusuntha pang'onopang'ono kumbali ya axial, kuti athetse vuto la kukulitsa ndi kutsika kwa shaft chifukwa cha kusintha kwa kutentha ndi kulakwitsa kwa malo omwe amaikidwa.Pazitsulo zazifupi, mbali yokhazikika ndi yosadziwika bwino ndi yaulere.

Chovala chokhazikika chimasankhidwa kuti chikhale cha axial positioning ndi kukonza chotengeracho kuti chibereke bidirectional axial load.Pakuyika, mphamvu yofananira iyenera kuganiziridwa molingana ndi kukula kwa axial katundu.Kawirikawiri, mayendedwe a mpira amasankhidwa ngati mapeto osasunthika komanso omasuka amasankhidwa kuti apewe.Kukula ndi kupindika kwa shaft komwe kumachitika chifukwa cha kusintha kwa kutentha panthawi yogwira ntchito, ndipo malo axial omwe amagwiritsidwa ntchito posinthira kunyamula kuyenera kunyamula katundu wozungulira, ndipo mphete yakunja ndi chipolopolo nthawi zambiri zimatengera chilolezo, kuti shaft ikhale axially. kupewedwa pamodzi ndi kunyamula pamene kutsinde likukulirakulira., Nthawi zina kupewa kwa axial kumapangidwa pogwiritsa ntchito malo ofananirako a shaft ndi mphete yamkati.Kawirikawiri, cylindrical roller bearing imasankhidwa ngati mapeto aulere mosasamala kanthu za mapeto okhazikika ndi mapeto aulere.Pamene kunyamula kumasankhidwa, pamene mtunda pakati pa mayendedwe ndi wochepa ndipo chikoka cha kukula kwa shaft ndi kakang'ono, gwiritsani ntchito mtedza kapena ma washers kuti musinthe chilolezo cha axial pambuyo poika.Nthawi zambiri, awiri amasankhidwa.Mipira yakuya ya groove kapena mayendedwe awiri ozungulira ozungulira angagwiritsidwe ntchito ngati chithandizo cha mapeto okhazikika ndi mapeto aulere kapena pamene palibe kusiyana pakati pa mapeto okhazikika ndi mapeto aulere.Kukwera ndi kutsika pafupipafupi komanso njira yokwezera ndi kutsika, monga kuwunika pafupipafupi, zida zoyikira ndi kutsitsa zimafunikira pakukweza ndi kutsika.Liwiro ndi katundu ndi zinthu ziwiri zofunika.Malingana ndi kuyerekezera pakati pa liwiro ndi kusinthasintha kwa malire, ndi kuyerekezera pakati pa katundu wolandiridwa ndi katundu wovomerezeka, ndiko kuti, moyo wotopa wovotera, mawonekedwe apangidwe amatsimikiziridwa.Zinthu ziwirizi zafotokozedwa pansipa.
