Kuyesa m'malo otsetsereka ndi kugubuduza kukhudzana kumawoneka kuti kunali kosangalatsa ngakhale m'nthawi yakale. Mliri wa chithunzicho ndi chojambula pakhoma ku Igupto. Mwala wawukulu ukunyamulidwa mosavuta pazipila zogubuduza zomwe zaikidwa pansi pake. Momwe zipika zomwe zimagwiritsidwa ntchito zimanyamulidwira kutsogolo zikuwonetsa momwe makina ozungulira amagwirira ntchito masiku ano.
Ngakhale kuti zoyenda zozungulira zozungulira zimayambira kalekale, sizinagwiritsidwe ntchito ngati zida zamakina mpaka kumayambiriro kwa zaka za m'ma 1900, pomwe ma bere oyenda okhala ndi mizere yozungulira amagwiritsa ntchito mipira yachitsulo pamayendedwe awo olondola komanso osalala. adathandizira kugwiritsa ntchito makina olondola.
The Basic mechanism of rolling elementzimbalangondo zoyendainakhazikitsidwa mu 1946 pamene kampani ya ku United States, Thomson, inagulitsa malonda a mpira (mtundu wokonzanso mpira). Maziko a maupangiri amasiku ano (magawo ogubuduza okhala ndi njanji) amatha kuwoneka mu patent yomwe idaperekedwa ku France mu 1932. Patent iyi, ngakhale ikuphatikiza ntchito zonse zofunika za maupangiri apamizere, idayenerabe kudikirira kwazaka zambiri ntchito yawo isanayambike pamsika. Panthawiyo, zida zingapo zamakina zomwe zimagwiritsa ntchito zinthu zogudubuza monga zomangira za mpira kapena splines za mpira zidagulitsidwa. Mitundu yosiyanasiyana ya ma bushings a mpira (mizere yozungulira mpira) idabweretsedwanso kumsika, kuphatikiza ma bere otseguka. Pakadali pano, zopanga zambiri komanso zokongoletsedwa zamitundu yofananira zidapangidwaotsogolera mzere.
Ife,PYG-Zhejiang Pengyin Technology Development Co., LTD, ndi makampani apamwamba kwambiri omwe amayang'ana kwambiri kafukufuku ndi chitukuko cha zigawo zowongoka bwino komanso mapangidwe apamwamba kwa zaka zoposa 20. Kuti akwaniritse zofuna zapadziko lonse lapansi, PYG ikupitiriza kukulitsa kupanga zida zopangira, kuyambitsa zida zotsogola zapadziko lonse lapansi ndiukadaulo wamakono, PYG imatha kupanga mizere yolondola kwambiri komanso yolondola kwambiri yocheperako kuposa 0.003 mm.
