Kusintha miyeso mavuto pambuyo kubala unsembe

Mukayika, musamenye molunjika kutsogolo ndi kopanda kupsinjika. Pakani chipika, manja kapena zida zina zoyikira ziyenera kugwiritsidwa ntchito kupanga mphamvu yofananira ya chimbalangondo. Osakhazikitsa ndikugudubuza thupi. Ngati kukwera pamwamba ndi mafuta, kumapangitsa kuti kuyikako kukhale kosalala. Ngati kusokonezedwa koyenera kuli kwakukulu, kuyenera kutenthedwa mpaka 80 ~ 90 ℃ mumafuta amchere ndikuyika posachedwa, kuwongolera kutentha kwamafuta sikupitilira 100 ℃, kuti tipewe kuchepetsa kuuma kwa kuuma komanso kukhudza kukula kuchira. Mukakumana ndi zovuta mu disassembly, ndi bwino kuti mugwiritse ntchito disassembly chida kukokera panja pamene mosamala kuthira mafuta otentha pa mphete yamkati, kutentha kumapangitsa kuti mphete yamkati ikhale yowonjezera, kuti ikhale yosavuta kugwa.

Sikuti mayendedwe onse amafuna chilolezo chochepa chogwirira ntchito, muyenera kusankha chilolezo choyenera malinga ndi momwe zilili. Padziko lonse lapansi 4604-93, chilolezo cha ma radial clearance of rolling bearings chimagawidwa m'magulu asanu: gulu 2, gulu 0, gulu 3, gulu 4 ndi gulu 5. chilolezo. Basic radial chilolezo gulu ndi oyenera zikhalidwe ntchito ambiri, kutentha ochiritsira ndi kusokoneza wamba zoyenera; Chilolezo chachikulu cha radial chiyenera kusankhidwa pazitsulo zomwe zimagwira ntchito pansi pazikhalidwe zapadera monga kutentha kwakukulu, kuthamanga kwambiri, phokoso lochepa komanso kukangana kochepa. Small zozungulira chilolezo ayenera kusankhidwa mwatsatanetsatane spindle ndi makina chida zitsulo zopota; Chilolezo chaching'ono chogwirira ntchito chikhoza kusungidwa kwa ma rola. Kuonjezera apo, palibe chilolezo cha kubereka kosiyana; Pomaliza, chilolezo chogwira ntchito chonyamula pambuyo pa unsembe chiyenera kukhala chaching'ono kuposa chilolezo choyambirira chisanakhazikitsidwe, chifukwa chonyamula chiyenera kunyamula kasinthasintha wina wa katundu, komanso kupunduka kwa zotanuka chifukwa cha kubereka koyenera ndi katundu.

Poganizira vuto la kusindikiza kwa ma bearings okhala ndi kusindikiza, pali njira ziwiri zomwe ziyenera kuchitidwa mosamalitsa pokonza.

1. Chisindikizo chosindikizidwa chosindikizira chimasinthidwa kumbali zonse ziwiri za kunyamula, ndipo mawonekedwe oyikapo amasinthidwa kuchokera ku zipangizo. Kulumikizana kwachindunji ndi kubereka sikofunikira, ndipo kuberekako ndi umboni wa fumbi kuchokera kunja kwa kubereka. Kusindikiza kwa kapangidwe kameneka ndikwapamwamba kuposa kunyamula komwe kumagulitsidwa ndi wothandizira, omwe amalepheretsa mwachindunji njira yowukira ya zinthu za granular ndikuwonetsetsa ukhondo wa mkati. Kapangidwe kameneka kamapangitsa malo otenthetsera kutentha kwa chotengera ndipo sichiwononga pang'ono pakuchita zotsutsana ndi kutopa kwa kubereka.

2. Ngakhale njira yosindikizira yakunja yonyamula imakhala ndi zotsatira zabwino zosindikizira, njira yochepetsera kutentha imatsekedwa, choncho zigawo zoziziritsa ziyenera kuikidwa. Chipangizo chozizira chimatha kuchepetsa kutentha kwa ntchito ya lubricant, ndipo kutentha kwapamwamba kwa mayendedwe kungapewedwe kupyolera mu kutentha kwachilengedwe pambuyo pozizira.
