Momwe mungapangire mabawuti otentha a dip kukhala abwinoko

Zomangamanga za ulusi ndi zina mwazinthu zofunika kwambiri pamakina opangira mphepo, milatho ndi zitsulo. Kuphatikiza pa zinthu zosiyanasiyana monga zida ndi zida, coefficient of friction ndi kusungidwa kwa ulusi wonse kumakhudzidwa kwambiri ndi nyengo zosiyanasiyana. Zomangira zingapo zolumikizira zikugwiritsidwa ntchito pano: ma seti a ISO bolt, ma seti a friction grip bolt, ndi ma seti a bawuti okhazikika, onse opangidwa ndi bawuti, chochapira chimodzi ndi nati. Monga lamulo, amapangidwa ndi zipangizo zamphamvu kwambiri. The coefficient of friction ndi chinthu chofunikira kwambiri cha zomangira zodalirika. Mtengowu umafotokoza kuchuluka kwa torque yodzaza ndipo zimatsimikiziridwa ndi zinthu ziwiri: kugundana kwa ulusi ndi kugundana kwamutu. Kuthamanga kwa katundu komwe kumagwira pamtunda ndiko kudzaza, komwe kumapangitsanso kuti bolt ikhale yotalika komanso momwe masika amayendera. Makokedwe, kumbali ina, amakhudza ulusi pamwamba ndi malo olumikizana, ndipo amagawidwa m'magawo atatu a torque: torque ya ulusi, kugundana kwamutu, ndi gawo lomwe limasinthidwa mwachindunji kukhala preload. Chifukwa chake, kuyika komaliza komaliza kuti mukwaniritse torque yotchulidwayo kumadalira kuchuluka kwa mikangano. Ma friction coefficients µges ndi k amakhudzidwa ndi zinthu zosiyanasiyana monga nthunzi, malo, mafuta kapena kuvala. Komabe, kutentha kozungulira, chinyezi ndi mvula zimakhudzanso kwambiri maulalo a ulusi. Apa, osati mapindikidwe zotanuka zimachitika, zimene zikafika poipa kwambiri kungachititse kuti ameta ubweya wa bawuti kapena kulephera kukwaniritsa preload chofunika. Izi zimadzetsa kuyimitsidwa kwa ntchito yomanga ndi kuwononga ndalama zambiri komanso kuchedwa kwa nthawi yokonzanso kapena kusintha magawo. Ichi ndichifukwa chake DÖRKEN ndi Peiner Umformtechnik adaganiza zopanga yankho limodzi. Peiner ndiwotsogola ogulitsa zomangira zama turbines amphepo ndi zida zachitsulo, zomwe zimapanga ma seti a bawuti okhazikika komanso ma seti a friction clamp bolt kukula kwake M12 mpaka M36. "Vuto la polojekiti yathu yogwirizana linali lokonzekera malata wamba omwe ali ndi zochapira zowonjezera komanso mtedza, zomwe zikutanthauza kuti mvula kapena dzuwa sizingakhudze kukhazikika kwa chomangira," akutero Christos, VP Sales, Industrial Coatings Tselebidis. anafotokoza. Delken. "Kuti tikwaniritse izi, tidayesa kwambiri ndikuyesa kozama kwa zinc flake topcoat kwa miyezi isanu ndi umodzi tisanapeze yankho la topcoat." Ngakhale kutentha kwa dip galvanizing ndi koyambira komwe kumateteza zolumikizira za ulusi kuti zisawonongeke, kugunda kwachitsulo cha zinc flake top coat kumatsimikizira kuti mtedzawo umangika bwino osachotsa chitetezo chilichonse cha dip dip galvanizing. Kuphatikiza pakuyesa kolimba kwambiri kwa ma labotale, mitundu ina ya zokutira yatsimikiziranso kufunika kwake pamayesero osiyanasiyana am'munda. "Zotsatira zake ndi zochititsa chidwi - pafupifupi ma bawuti 3 miliyoni aperekedwa ndikuyika popanda kulephera," akutero Valery Shram, Mtsogoleri wa Structural Engineering ndi Wind Energy ku Peiner Umformtechnik. zimatsimikizira kuti njira zodalirika zomwe sizinawonedwepo m'mbuyomu zitha kukwaniritsidwa pamalo omanga." Claire wakhala akugwira ntchito m'makampani opanga makina kwa zaka khumi ndipo wakumana ndi zinthu zonse kuchokera ku mphero zazitsulo, opanga ma fasteners, ogulitsa, ogulitsa, ogulitsa, komanso omanga makina ndi makampani opanga ma electroplating. Claire amadziwa zomangira. Kumvetsetsa mozama mbali zonse. Kuphatikiza pa kuyendera makampani ambiri, ziwonetsero zamalonda ndi misonkhano padziko lonse lapansi, a Claire amafunsa anthu otchuka, akuyang'ana pamitu yofunika kwambiri yomwe ikukhudza makampani komanso kudziwitsa owerenga zomwe zachitika posachedwa pamsika.
