Yuav ua li cas txiav txim siab qhov peev xwm ntawm nylon casters
Kev txiav txim siab lub nra ntawm nylon casters yuav tsum muaj kev ntsuas dav dav raws cov khoom lag luam cim, cov khoom tsim, thiab cov ntaub ntawv siv tiag tiag. Tus tseem ceeb tuaj yeem faib ua plaub kauj ruam hauv qab no:

Ua ntej, ua ntej txheeb xyuas cov khoom lag luam sau npe. Nylon casters tsim los ntawm cov neeg tsim khoom siv nrov nrov yuav muaj ib qho "rated load muaj peev xwm" qhia nyob rau ntawm lub log lub cev, log thau, lossis phau ntawv qhia cov log. Tus nqi no sawv cev rau cov chaw tsim khoom ntawm cov chaw tsim khoom rau kev txiav txim siab rau kev nyab xeeb los ntawm kev sim kev tshaj lij thiab yog ib qho tseem ceeb kom them sai sai rau. Nws yog ib qho tseem ceeb kom paub qhov txawv ntawm "ib qho {{{}} lub log load muaj peev xwm" thiab "tiav Cable Cable muab load muaj peev xwm." Piv txwv li, yog tias ib pawg ntawm plaub lub CASters muaj lub nqi zog thauj khoom muaj peev xwm ntawm 150kg ib lub log, theoretical load muaj peev xwm ntawm cov txheej tiav yog 600kg. Txawm li cas los xij, hauv kev siv tiag tiag, ib qho 20% -30% npoo yuav tsum tau tshwj tseg kom tiv thaiv kev sib tshooj thiab cov chaw thauj khoom tsis sib xws.

Thib ob, kwv yees raws cov nylon cov khoom siv. Lub nra hnyav muaj peev xwm ntawm ib lub log ua los ntawm dog dig unmodified nylon (xws li PA6 thiab PA66) yog 50 {}} 200kg. IAV -} reasleed nylon (xws li 30% iav fiber) tuaj yeem ncav cuag 200-500 kg vim nws lub zog siv zog ntxiv. Tshwj xeeb engineered nylon (xws li PA12 thiab PA46) lossis composite compified nylons muaj ntau lub log muaj peev xwm nqa tau tshaj 500kg. Nws yog ib qho tseem ceeb kom nco ntsoov tias lub log lub cheeb tsam tseem cuam tshuam rau kev thauj khoom muaj peev xwm. Rau tib cov ntaub ntawv, lub cheeb tsam loj dua cov chaw muaj peev xwm ntau dua (piv txwv li ntau dua, lub hlis twg los load muaj peev xwm ntau dua li 75mm diam log ntawm tib tus qauv).

Tsis tas li ntawd, xyuas lub zog ntawm tus qauv meter thiab cov khoom siv. Lub thauj khoom muaj peev xwm nyob ntawm tsis tsuas yog nyob ntawm lub log nws tus kheej tab sis kuj nyob rau Cheebtsam xws li lub log thav duab, bearings, thiab qag pins. Yog tias lub hnab ntim khoom dua yog ua los ntawm txias txias- Tus hlau thiab yog tsawg kawg nkaus 2 hli tuab heev yog farIn farpos thav ntawv. Xaiv cov pob los yog rab koob rau cov kabmob, raws li lawv disperse siab thiab txhim kho kev tsim hluav taws xob piv rau cov qauv tsim tshwj xeeb. Ib qho loj dua lub taub dej loj (piv txwv li, 8mm lossis loj dua) muab ntau dua shear tsis kam thiab tsis tshua ua txhaum. Yog tias muaj cov txheej txheem xaus (piv txwv li, kev tawm suab lossis kev coj tus xoob), tus kwv yees lub peev xwm yuav tsum tau txo.

Thaum kawg, kev kho kom haum yuav tsum tau ua raws li kev siv cov xwm txheej tiag tiag. Yog tias yuav siv cov khoom siv rau hauv cov chaw sib tsoo (piv txwv li, cov khoom muaj peev xwm ua kom muaj kev ntsuas (piv txwv li ntawm kev siv nyiaj ntau dhau los ua los ntawm kev co lossis cov rog tom qab. Rau ntev - lub sij hawm} Lub sij hawm zoo li qub Rau cov kabmob dynamic lo (piv txwv li, thawb lub laub), cov npoo ntxiv yuav tsum muab los tiv thaiv kev puas tsuaj los ntawm kev pib lossis nres.
