Zipangizo ndiye maziko a zinthu zopangira. Kupanga kumafuna kugwiritsa ntchito zipangizo mosalekeza. Nthawi yofunikira kuti zipangizo zigwiritsidwe ntchito ndi yayitali, ndipo nthawi yokonza zida iyenera kuchepetsedwa. Pali kusiyana pakati pa kupanga ndi kukonza zida. Kasamalidwe ka sayansi ndi kukonza Zipangizo zikadali zofunika kwambiri.
Kuti apange bwino ntchito yokonza zida, ogwira ntchito yokonza zida ayenera kudziwa momwe zida zimagwirira ntchito, kumvetsetsa kapangidwe ndi mfundo za zida, kudziwa momwe angasamalire zida, kudziwa momwe angakhazikitsire ndikusamalira zida, komanso kudziwa bwino kukula kwa zida. Pa nthawi yokonza yapakatikati, kugwiritsa ntchito bwino zida zosinthira, komanso kukonza bwino zida kuti zibwezeretse magwiridwe antchito a zida kungathandize kukonza luso la kasamalidwe kaukadaulo wa zida.
Ma shaft akuluakulu ndi ma motor shaft a zida zogwirira ntchito monga ma compressor, mafani, ndi mapampu a centrifugal nthawi zambiri samakhala osavuta kuvala ndi kuwononga, pokhapokha ngati kupotoka kwa kulumikizana kwa cholumikizira kuli kwakukulu kwambiri, kapena nati yotsekera ya bearing siikutsekedwa, kapena nangula Mlingo wolimba wa ma bolts sukwaniritsa zofunikira ndipo umamasuka panthawi yogwira ntchito ya zida, kapena kusonkhana kwa ma motor bearing sikukwaniritsa zofunikira, ndi zina zotero, zomwe zimapangitsa kuti shaft iwonongeke ndikuwonongeka.
Malo omwe shaft yawonongeka chifukwa cha kuwonongeka nthawi zambiri amakhala pamalo operekera. Ndi kusiyana pakati pa bearing ndi shaft komwe kumapangitsa kuti zida zisagwire ntchito bwino. Mphete yakunja ya bearing yozungulira ndi shaft yowunikira, ndipo dzenje la mpando wofanana, ena amagwiritsa ntchito kukula kwa dzenje lowunikira, ndipo ena amagwiritsa ntchito kusintha komwe kumapangidwa ndi shaft yoyambira; bwalo lamkati la bearing yozungulira ndi dzenje lowunikira, ndipo shaft yofananira imagwiritsa ntchito kukula kwa dzenje lowunikira. Kulumikizana pang'ono. Mphete yakunja ndi dzenje la bearing la mabearing ozungulira nthawi zambiri sizimavalidwa kawirikawiri. Ngakhale mphete yakunja ya bearing ndi dzenje la bearing yokhala ndi malo otseguka, kuwonongeka kwa dzenje la bearing housing ndi kochepa kwambiri. Malo omwe shaft imavala kwambiri chifukwa cha kusagwira bwino ntchito kwa zida nthawi zambiri amakhala pamalo operekera shaft. Ngati malo operekera shaft atha, padzakhala kusiyana pakati pa mphete yamkati ya bearing yozungulira ndi shaft, zomwe zimapangitsa bearing "kuyendetsa bwalo lamkati". Izi zimafuna kukonza malo operekera shaft kuti ifike pa kukula kwake koyambirira.
Pali njira zitatu zazikulu zokonzerera malo ochitira zinthu zoberekera: imodzi ndi kupanga "diso lachilendo" lolimba pamalo ochitira zinthu zoberekera a shaft, kotero kuti mphete yamkati ya bearing ndi shaft sizingamasulidwe, koma malo ochitira zinthu zoberekera sangakhale coaxial ndi shaft yayikulu, koma ndi kwakanthawi kuti athane ndi kukonza. Ina ndikuchita welding pamalo ochitira zinthu zoberekera, yesani kuonetsetsa kuti shaft siikuwonongeka panthawi yoweta, kenako n’kuikonza pa lathe pambuyo poweta. Kukonza kumeneku kungatsimikizire kuti shaft ikugwira ntchito bwino, koma ntchito yokonza ndi yovuta kwambiri. Ina ndikugwiritsa ntchito chitsulo chokonzera zinthu zoberekera pamalo ovulala. Wokonza akauma, gwiritsani ntchito fayilo, nsalu ya emery, chopukusira, rula, vernier caliper, ndi zina zotero kuti muikonze pamanja. Popeza yakonzedwa pamanja, siingatsimikizire malo okonzera zinthu zoberekera. Shaft yayikulu ndi coaxial, ndipo m'mimba mwake mulinso zopinga. Panthawi yoyeserera, zida zimagwedezeka kwambiri, ndipo zida zina sizingagwire ntchito bwino.
