PTFE Slide Bearings

Zigawo zonyamula zimatha kupezeka pakuyika ndi bolting, tack-welding, kuwotcherera kwathunthu kapena kuyika matope, ndipo mtundu woyenera wa kunyamula uyenera kusankhidwa molingana ndi njira yoyika.The PTFE ayenera mokwanira kutetezedwa ku weld spatter, utoto kutsitsi, zitsulo swarf etc, pa unsembe.

Mu ntchito zosiyanasiyana, PTFE Slide mayendedwe ndi apamwamba kuposa mbale ochiritsira ochiritsira, odzigudubuza ndi rocker mkono mtundu zothandizira.Amathandizira chomera cha petrochemical, makina olemera, mapaipi, nyumba ndi zomangira mlatho;amalola kukulitsa, kupindika ndi kusinthasintha kwina kulikonse komwe kumayenda chifukwa cha kutentha, zivomezi kapena mphamvu zosiyana.

Bearings za ntchito zotere ziyenera kugwira ntchito zolemetsa kwambiri komanso zothamanga kwambiri, ndipo zili pansi pazimenezi kuti katundu wodzipangira yekha wa PTFE ali pazipita.Izi, pamodzi ndi mawonekedwe ake opanda ndodo komanso odana ndi nyengo, ndiye chifukwa chake PTFE yakhala yopambana kwambiri ngati slide bearing material.

Ubwino wake

1 Kuphweka kwa mapangidwe ake ndi kuphweka kwake kupanga ndi kuyika kumapangitsa kuti mtengo ukhale wokwera mtengo.2 Mtengo wa zomangamanga ukhoza kuchepetsedwa popanga kukulitsa m'malo movutikira.3 Coefficient of friction on the bearing surface imakhalabe yosasinthasintha, ngakhale pansi. zinthu zoipa kwambiri.4 Zimbalangondo ndi yokonza kwaulere - PTFE ndi mwachibadwa kudzipaka mafuta, pamene dothi particles odzipereka mu zakuthupi.Chitetezo chosavuta chokha chimafunikira pakulowa kwakukulu kwa dothi.

Coefficients of Friction

The coefficient of friction of PTFE materials imadalira zosiyanasiyana zosiyanasiyana, kuphatikizapo kuthamanga, kutsetsereka liwiro ndi kutentha.Malingaliro amagawanika pa zotsatira za zosintha zina, ngakhale amavomereza kuti kuthamanga kwambiri ndi kutsika kwachangu kumakonda kukangana kochepa.

Coefficient ndi yocheperako kuposa yazinthu zina zilizonse zolimba zaukadaulo.Zanenedwa mosiyanasiyana kuyambira 0.02 mpaka 0.2, koma izi zimatengera kukonzekera pamwamba ndi njira yoyesera.Tchati cha katundu / mikangano ikuwonetsa zotsatira za katunduyo.

Kawirikawiri, coefficient of friction pakati pa mating pamwamba ndi PTFE slide kubala pad adzakhala osachepera pamene kupsyinjika mu PTFE ndi pa pazipita (zogwirizana ndi zovomerezeka malire amakwawa), kubereka anapangidwa kuchokera unfilled PTFE, ndi mapeto a mating pamwamba amapukutidwa kwambiri.

Komanso, chimodzi mwa zinthu zofunika kwambiri frictional makhalidwe a PTFE ndi kusowa kwa 'ndodo-kutsetsereka', chifukwa mosiyana ndi mayendedwe ena onse ochiritsira, ndi malo amodzi kukangana wa PTFE ndi wofanana kapena pang'ono apamwamba kuposa kukangana zazikulu.
