Kugawidwa ndi njira yotsekera mphete yamkati (mndandanda itatu yayikulu)
Mndandanda wa UC: ya makina a zaulimi, mafani, zida zonyamulira, makina ophikira chakudya, ndi zina zotero, m'malo okhala ndi liwiro lapakati komanso katundu wokhazikika
Mndandanda wa UEL/UE: umagwiritsidwa ntchito kwambiri pamakina opangira nsalu, makina olongedza, ndi zina zotero, pazida zapakati zomwe zimafuna luso linalake losintha.
Mndandanda wa UK: woyenera zida zomwe zili ndi liwiro lozungulira kwambiri, katundu wolemera, kapena zomwe zimafunika kuchotsedwa ndi kusonkhana pafupipafupi, monga makina ena omanga ndi zida zamigodi. Amagawidwa malinga ndi mawonekedwe a nyumba yosungiramo zinthu (mitundu ya nyumba wamba) Nyumba yosungiramo zinthu ndi "mawonekedwe" okhazikitsa, ndipo mawonekedwe osiyanasiyana amatsimikizira njira yokhazikitsira ndi malo okhala. Tanthauzo la zilembo zodziwika bwino m'makhodi a mtundu wa nyumba ndi awa: P (wowongoka), F (sikweya), FL (rhombic), T (slider), C (wozungulira), ndi zina zotero.
Chitsulo chopangidwa ndi chitsulo chimagwiritsidwa ntchito popanga zinthu zonse, ndi mphamvu zambiri komanso kulimba, ndipo ndi mtundu womwe umagwiritsidwa ntchito kwambiri.
Nyumba yoyima: mtundu womwe umagwiritsidwa ntchito kwambiri. Ma code monga UCP, UCFP, ndi oyenera kugwiritsa ntchito zida wamba.
Nyumba ya sikweya: codeUCF, yokhala ndi malo oyikapo sikweya, nthawi zambiri imakhala ndi mabowo anayi oyikapo, ndipo ili ndi kapangidwe kakang'ono.
Nyumba ya Rhombic: code UCFL, yokhala ndi malo oyika rhombic, yoyenera kugwiritsidwa ntchito m'malo okhala ndi malo ochepa kapena komwe kukufunika kukhazikika m'mbali.
Nyumba yotsetsereka: khodi ya UCT, yokhala ndi nyumba yonyamulira yomwe imatha kutsetsereka m'malo mwake, yoyenera zochitika zomwe kupsinjika kwa malamba ndi unyolo kuyenera kusinthidwa.
Nyumba yozungulira: code UCC, yokhala ndi mawonekedwe ozungulira, yomwe nthawi zambiri imagwiritsidwa ntchito pa mapaipi ndi zida zozungulira.
Nyumba yoyimirira pakati (UCPH): yokhala ndi kutalika kwapakati kuposa nyumba yoyimirira wamba, yoyenera mtunda wapadera woyikira.
Chipinda choyimitsira/chopachikika (UCHA/UCB): choyimitsira, choyenera kuyikidwa pamwamba pa galimoto kapena makina apadera.
Nyumba zomangika: monga PF, PFL, PFT, zopangidwa ndi mapepala achitsulo oponderezedwa, okhala ndi mtengo wotsika komanso wopepuka, nthawi zambiri amagwiritsidwa ntchito pazida zosafunikira kwambiri zokhala ndi katundu wochepa.
Dziwani: Chigawo chimodzi cholumikizira nthawi zambiri chimatchedwa "bearing code + housing type code". Mwachitsanzo, UCP205, imayimira bearing yamkati ya UC205 ndipo imayikidwa mu vertical (P) house.
Kuti musankhe chotengera choyenera kwambiri, tikukulimbikitsani kutsatira njira zotsatirazi:
Fotokozani momwe ntchito ikuyendera: dziwani kukula kwa katundu (wozungulira/wozungulira), liwiro, kutentha kwa ntchito, ndi malo ozungulira (monga fumbi, chinyezi, kuwonongeka).
Dziwani njira yotsekera: kutengera ngati njira yozungulira ya shaft ndi yokhazikika, mulingo wa liwiro, komanso kuchuluka kwa kusweka, sankhani kuchokera ku mndandanda wa UC, UEL, UK.
Sankhani mawonekedwe a nyumba: kutengera malo oikira, malo, ndi njira yolumikizira yomwe yaperekedwa ndi zidazo, sankhani mtundu woyenera wa nyumbayo.
Tsimikizirani kukula kwa malo oyika: yang'anani kwambiri pakuwunika miyeso yofunika monga kukula kwa shaft, kutalika kwa pakati, ndi malo oyika mabowo kuti muwonetsetse kuti ikugwirizana ndi kapangidwe kake komwe kalikonse.
Ganizirani momwe zinthu zingagwiritsidwire ntchito pokonza: sankhani ma bearing okhala ndi ma doko amafuta ndi magwiridwe antchito abwino otsekera kuti muchepetse kukonza pambuyo pake ndikuwonjezera nthawi yogwira ntchito.
