Dziko la uinjiniya wamakina limadalira kuzungulira kosalala komanso kolondola kwa chinthu chooneka ngati chosavuta: bearing. Kuyambira ma rotor akuluakulu a wind turbine mpaka ma spindles ang'onoang'ono mu hard drive, ma bearing ndi ngwazi zosaimbidwa zomwe zimathandiza kuyenda. Kulondola kwa bearing—kuzungulira kwake, kuthamanga kwake, ndi kutha kwake pamwamba—ndikofunikira kwambiri pa magwiridwe antchito ake ndi moyo wake. Koma kodi kusiyana kwa microscopic kumeneku kumayesedwa bwanji molondola kwambiri? Yankho silili m'zida zamagetsi zamakono zokha, komanso m'maziko okhazikika, osagwedezeka: nsanja yolondola ya granite. Ku ZHONGHUI Group (ZHHIMG®), tawona momwe ubale wofunikira pakati pa maziko okhazikika ndi chida chomvera ukusinthira gawo la metrology ya bearing.
Vuto: Kuyeza Chosaoneka
Kuyang'anira ma bearing ndi gawo lovuta kwambiri la metrology. Mainjiniya ali ndi ntchito yoyesa mawonekedwe a geometric monga radial runout, axial runout, ndi concentricity ku sub-micron kapena nanometer tolerances. Zipangizo zomwe zimagwiritsidwa ntchito pa izi—monga CMMs, roundness testers, ndi ma laser system apadera—ndizosavuta kumva. Kugwedezeka kulikonse kwakunja, kutentha, kapena kusintha kwa kapangidwe ka maziko oyezera kumatha kuwononga deta ndikupangitsa kuti mawerengedwe abodza.
Apa ndi pomwe mphamvu zapadera za granite zimagwira ntchito. Ngakhale chitsulo chingaoneke ngati chisankho chanzeru kwambiri pa maziko a makina, chili ndi zovuta zazikulu. Chitsulo ndi chowongolera kutentha chabwino, chomwe chimapangitsa kuti chikule ndikuchepa ngakhale kutentha pang'ono. Chilinso ndi coefficient yotsika yonyowa, zomwe zikutanthauza kuti chimatumiza kugwedezeka m'malo mozitenga. Pa choyimilira choyesera cha bearing, ichi ndi cholakwika chachikulu. Kugwedezeka pang'ono kuchokera ku chipangizo chakutali kumatha kukulitsidwa, zomwe zimapangitsa kuti muyeso ukhale wolakwika.
Chifukwa Chake ZHHIMG®'s Granite Ndi Maziko Abwino Kwambiri
Ku ZHHIMG®, takonza bwino kugwiritsa ntchito ZHHIMG® Black Granite pakugwiritsa ntchito molondola kwambiri. Ndi kuchuluka kwa pafupifupi 3100kg/m3, granite yathu ndi yolimba kwambiri kuposa zipangizo zina. Umu ndi momwe imagwirizanirana ndi zida za metrology kuti ikwaniritse kulondola kosayerekezeka pakuyesa ma bearing:
1. Kuchepetsa Kugwedezeka Kosayerekezeka: Mapulatifomu athu a granite amagwira ntchito ngati chodzipatula chachilengedwe. Amayamwa bwino kugwedezeka kwa makina kuchokera ku chilengedwe, kuwaletsa kufika pa ma probe oyesera osavuta komanso bearing yomwe ikuyesedwa. Mu workshop yathu yolamulidwa ndi nyengo ya 10,000m2, yomwe ili ndi pansi pa konkriti wokhuthala kwambiri komanso ngalande zotsutsana ndi kugwedezeka, timasonyeza mfundo iyi tsiku lililonse. Kukhazikika kumeneku ndi sitepe yoyamba, yofunika kwambiri pakuyesa molondola.
2. Kukhazikika Kwambiri kwa Kutentha: Kusintha kwa kutentha ndi chifukwa chachikulu cha zolakwika mu metrology. Granite yathu ili ndi coefficient yochepa kwambiri ya kukula kwa kutentha, zomwe zikutanthauza kuti imakhalabe yokhazikika ngakhale kutentha kwa mlengalenga kukusintha pang'ono. Izi zimatsimikizira kuti pamwamba pa nsanjayo—ziro-point pa miyeso yonse—sikusuntha. Kukhazikika kumeneku ndikofunikira kwambiri pa nthawi yayitali yoyezera, komwe ngakhale kukwera pang'ono kwa kutentha kungasokoneze zotsatira zake.
3. Mzere Wabwino Kwambiri Wofotokozera: Kuyesa ma bearing kumafuna malo ofotokozera opanda cholakwika. Akatswiri athu aluso, omwe ali ndi zaka zoposa 30 zokumana ndi manja, amatha kumaliza nsanja zathu za granite mpaka kufika pamlingo wodabwitsa, nthawi zambiri kufika pamlingo wa nanometer. Izi zimapereka malo olinganizidwa bwino kuti zida zizigwiritsidwa ntchito, kuonetsetsa kuti muyeso wake ndi wa bearing yokha, osati maziko ake. Apa ndi pomwe Ndondomeko Yathu Yabwino imagwirira ntchito: "Bizinesi yolondola singakhale yovuta kwambiri."
Kuphatikiza ndi Zida
Ma granite surface plates ndi ma custom bases athu apangidwa kuti azigwirizana bwino ndi zida zosiyanasiyana zoyesera ma bearing. Mwachitsanzo, choyesera chozungulira—chomwe chimayesa momwe bearing imapatuka kuchoka pa bwalo langwiro—chimayikidwa pa nsanja ya granite kuti chichotse phokoso lililonse logwedezeka. Bearing imayikidwa pa granite V-block kapena fixture yokonzedwa, kuonetsetsa kuti yasungidwa bwino komanso molondola motsutsana ndi reference yokhazikika. Masensa ndi ma probe amayesa kuzungulira kwa bearing popanda kusokonezedwa. Mofananamo, pa ma CMM omwe amagwiritsidwa ntchito poyang'anira ma bearing akuluakulu, maziko a granite amapereka maziko olimba komanso okhazikika ofunikira kuti ma axel oyenda a makinawo agwire ntchito molondola.
Ku ZHHIMG®, timakhulupirira njira yogwirira ntchito limodzi. Kudzipereka kwathu kwa Makasitomala ndi "Osachita chinyengo, Osabisa, Osasokeretsa". Timagwira ntchito ndi mabungwe otsogola a metrology ndi ogwirizana nawo padziko lonse lapansi kuti tipange ndikukonza nsanja za granite zomwe zikugwirizana bwino ndi zofunikira zenizeni zowunikira ma bearing. Timadzitamandira kukhala maziko chete, osasuntha omwe miyeso yolondola kwambiri padziko lonse lapansi imapangidwa, kuonetsetsa kuti kuzungulira kulikonse, mosasamala kanthu kuti ndi kwachangu kapena pang'onopang'ono bwanji, kumakhala kwangwiro momwe kungakhalire.
