Mukayika, musamenye molunjika kutsogolo ndi kopanda kupsinjika.Press block, sleeve kapena zida zina zoyika ziyenera kugwiritsidwa ntchito kupanga mphamvu yofananira ndi 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 amafunikira chilolezo chocheperako, 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 chogwira ntchito chikhoza kusungidwa kwa mayendedwe odzigudubuza.Kuphatikiza apo, palibe chilolezo cha kubereka kopatukana;Pomaliza, chilolezo chogwira ntchito cha chonyamulira pambuyo pa unsembe chiyenera kukhala chaching'ono kuposa chilolezo choyambirira chisanakhazikitsidwe, chifukwa chotengeracho chiyenera kunyamula kasinthasintha wina wa katundu, komanso kupunduka kwa zotanuka chifukwa cha kubereka 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 momwe zimakhalira zomwe zimagulitsidwa ndi wothandizira, zomwe zimalepheretsa mwachindunji njira yowonongeka ya zinthu za granular ndikuonetsetsa kuti mkati mwake muli ukhondo.Kapangidwe kameneka kamapangitsa kuti malo otenthetsera kutentha apangidwe ndipo samawononga pang'ono pakuchita zotsutsana ndi kutopa kwa chiberekero.
2. Ngakhale kuti njira yosindikizira yakunja imakhala ndi zotsatira zabwino zosindikizira, njira yochepetsera kutentha imatsekedwa, choncho zigawo zoziziritsa ziyenera kuikidwa.Chipangizo chozizira chimatha kuchepetsa kutentha kwa ntchito ya mafuta, ndipo kutentha kwapamwamba kwa mayendedwe kungapewedwe kupyolera mu kutentha kwachilengedwe pambuyo pozizira.
