Kunyamula ndi gawo lothandizira shaft m'makina, ndipo shaft imatha kuzungulira pazomwe zikuchitika. China ndi chimodzi mwazimwezi zoyambirira padziko lapansi kuti padziko lapansi lizipanga rillings. M'mabuku akale achi China, kapangidwe ka axle kwalembedwa kale. "
Mbiri Yachitukuko yokhudzana ku China
Zaka zikwi zisanu ndi zitatu zapitazo, zosewerera zamagalimoto pang'onopang'ono zimawonekera ku China
Gudumu la woumba ndi disc ndi shaft yowongoka. Dongo losakanikirana kapena dongo loyipa limayikidwa pakati pa gudumu kuti lizipanga gudumu, pomwe dongo limapangidwa ndi dzanja kapena lopukutidwa ndi chida. Maluwa ophulika pa liwiro lake limagawidwa ndi gudumu lothamanga komanso kuwonda pang'ono, inde, gudumu lothamanga limapangidwa pamaziko a gudumu locheperako. Malinga ndi zojambula zakale kwambiri zaposachedwa, gudumu lofulumira lidabadwa, kapena kusinthidwa, zaka 8,000 zapitazo. Mu Marichi 2010, mawilo a mitengo ya cutten a Cuahuqao amapezeka patsamba la quahuqao, lomwe limatsimikizira kuti ukadaulo wa vatery ku China anali woposa zaka zoposa 2000 zapitazo kuposa kuti kumadzulo kwa Asia. Ndiye kuti, China iyamba kugwiritsa ntchito mavalidwe, kapena mfundo ya kugwiritsa ntchito mapepala, m'mbuyomu kuposa Asia.
Mbali yamatanda ya cutten ili ngati nsanja ya trapezoidal, ndipo pali silinda yaying'ono pakati pa nsanja, yomwe ndi shaft ya magudumu. Ngati kugwedezeka kumapangidwa ndikuyikidwa pamatumba a supn cutter, gudumu lathunthu la mbiya chidzabwezeretsedwa. Pambuyo pa guwa lamphamvu limapangidwa, thumba lonyowa limayikidwa pambale yozungulira ndikusagwirizana mosamala. Plate yozungulira imazungulira ndi dzanja limodzi ndipo tayala lomwe limakwezedwa limakonzedwa limalumikizidwa ndi matabwa, fupa kapena miyala yomwe ili ndi dzanja linalo. Pambuyo pamayendedwe angapo, chingwe chozungulira chomwe chingachitike pa tayala. Monga tafotokozera pamwambapa, kusandulika kumakhudzidwa pano, ndipo pali shaft yothandizira, yomwe ndi yolondola yazomwe zikubereka.
Kapangidwe ka gudumu lamphamvu kumawonetsedwa m'chigawo pansipa:
Chithunzichi pansipa ndicho kubwezeretsanso gudumu lothamanga, lomwe limakhazikitsidwa pa gudumu lothamanga ku Tang mzera wamfumu. Ziyenera kukhala zapamwamba kwambiri kuposa gudumu lokhazikika, koma mfundozo zimakhalabe chimodzimodzi, kupatula kuti zinthuzo zimasinthidwa kuchokera ku nkhuni kupita ku chitsulo.
