Yuav ua li cas Nylon casters ua rau sab nraum zoov cov plag tsev?

Kev tsom xam ntawm kev ua tau zoo thiab sib xyaw ntawm nylon casters nyob sab nraum zoov vaj tse nyob sab nraud
Sab nraum zoov cov plag tsev (feem ntau tsis tau muab cov pob zeb ua kom zoo dua los yog tsis {{0} {} {tsis muaj qhov ua kom muaj kev cuam tshuam loj, thiab muaj cov kev hloov pauv loj, thiab muaj cov kev hloov pauv loj, thiab muaj cov kev hloov pauv loj. Cov kev ua tau zoo ntawm nylon casters yuav tsum tau txiav txim siab raws li cov khoom siv (hnav} tiv taus tab sis muaj zog tiv thaiv huab cua). Zuag qhia tag nrho, lawv pom "hnav {{4 4}}}}}} {tiv taus tab sis nrog qee qhov kev txwv," raws li cov ncauj lus kom ntxaws hauv qab no:

 

I. Cov ntsiab lus zoo: Hnav Cov Khoom Siv Ya Dej Kom Tsis Yooj Yim Rau Cov Hnyav Rau Cov Hnyav, muab cov ruaj ruaj thauj khoom {{1} {cov kabmob muaj peev xwm
Siab coj kev tawm tsam thiab kev ua siab ntev rau kev sib txhuam hauv av
Nylon (tshwj xeeb yog iav {{- fiber ntau dua (rockwell hardness ntau dua los yog sib npaug. Tiv thaiv ntau dua li cov roj roj roj hmab zoo li qub. Thaum dov ntawm sab nraum zoov cov plag tsev, nws tuaj yeem tiv thaiv tau los ntawm gravel thiab me me bumps- sib piv rau cov roj hmab log, uas muaj ntau dua kev hnav vim yog cov ntxhib cov chaw. Nylon log muaj cov nqi qeeb qeeb dua li roj hmab log, tsis suav nrog cov ntug Fuzz thiab cov ntoo hauv zos. Thaum siv ntawm lub teeb - rau nruab nrab {9} Cov khoom siv rebar qis dua lossis sib npaug ntawm 1-2 xyoos, 30% ntev dua li cov log roj hmab.

 

Zoo heev load - bearing} bearing rabe thiab muaj zog rau deformation. Nylon lub zog kho tshuab zog ua rau nws tsis tshua muaj cov log hauv tsev, xws li nqa cov khoom siv hluav taws xob hnyav, thaum nqa cov khoom siv hluav taws xob hnyav Nylon log tswj lawv cov duab puag ncig, tiv thaiv kev ncua rab los ntawm kev deformation log. Lawv tsim nyog rau kev siv sab nraum zoov uas yuav tsum muaj cov chaw nyob ruaj khov, xws li cov khoom siv sib tw ntawm cov chaw tsim khoom thiab cov khoom siv txhawb nqa sab nraud sab nraud. Kev tiv thaiv huab cua tiv thaiv huab cua, hloov tau rau sab nraum zoov kub hloov pauv.

 

Zoo dog dig nylon tuaj yeem tiv taus sab nraum zoov qhov kev hloov pauv sab nraud ntawm 60℃(piv txwv li cov plag tsev mus txog 60℃hauv lub caij ntuj no) tsis muaj qhov muag pom kev muag muag lossis tawg. Huab cua-resistant hloov nylon (nrog ntxiv Uv inibitors thiab antioxidants thiab tiv thaiv brittleness thiab kev tawg ntawm lub log tsuj. Nws yog qhov haum rau sab nraum zoov ib puag ncig hauv feem ntau thaj tsam (tshwj tsis yog cov chaw kub uas kub siab tshaj 80℃lossis qis qis qis qis dua hauv qab-16 degree).

 

Ii. Cov shortcomings loj: tsis muaj zog elasticity thiab yooj yim cuab yeej ntawm impurities, kev cuam tshuam cov neeg siv khoom thiab kev ua neej.

Txom nyem elasticity, tseem ceeb kev co thiab cov teeb meem suab nrov.

Nylon muaj cov modulity loj heev (kwv yees li 2.8 GPA), ntau dua qis dua roj hmab (kwv yees 0.005 GPA). Thaum dov ntawm sab nraum zoov cov plag tsev (uas feem ntau muaj cov kab tawg thiab tsis sib luag), nws tsis tuaj yeem ua pob txha pob thiab cov chaw xa khoom hauv av ncaj qha rau cov cuab yeej. Qhov no tuaj yeem ua rau cov ntaub ntawv yuam kev thaum siv los nqa cov cuab yeej precision (xws li sab nraum zoov ntsuas ntsuas lub tawb ntsuas). Tsis tas li ntawd, kev sib tw sib tiv tauj cov suab nrov siab (cov suab nrov dua> 60 --20 decibels rouder tshaj qhov tseem ceeb (xws li tu cov cuab yeej nyob ze cov chaw nyob). Impurities yooj yim tau nyam, ua kom nrawm nroos hnav thiab jamming.

 

Cov Flasor Caas sab nraum zoov muaj feem dhau los tuav cov khib nyiab xws li xuab zeb, plua plav, thiab nplooj poob. Qhov sib txawv ntawm cov nylon tawb lub cev thiab lub log thav duab (tshwj xeeb yog cov qauv tsis muaj kev sib tsoo nrog cov xuab zeb thiab pob zeb me me. Qhov no tuaj yeem ua: ① Cov ris nrawm nrawm (xuab zeb thiab gravel rubbing tawm tsam cov xeeb ntxwv sab hauv phab ntsa); ② Lub zog hauv zos concentration ntawm lub log nto (impurities tau daig ntawm lub log tsheb thiab hauv pem teb, tsim kev sib cuag tsis xwm yeem " Yog tias tsis ntxuav tsis tu ncua, qhov no tuaj yeem ua rau lub neej ua ntej tsis ua tiav (ua kom ntev li qub {}} purses} xyoo lifesp rau tsawg dua rau lub hlis). Kev cuam tshuam tsis muaj zog tiv thaiv ua rau lawv raug kev puas tsuaj los ntawm cov khoom ntse, cov khoom tawv.

 

Nylon ua lub zog ntawm tsawg kub (kev txo qis qis dua hauv qab -10 degree). Yog tias lub hnab nylon tawm sab nraum zoov pob zeb ua ke nrog cov rebar (xws li cuam tshuam cov rebar los yog pob zeb), nws tuaj yeem tawg yooj yim lub log lossis txawm so. Piv rau roj hmab log, uas cushion cuam tshuam los ntawm elasticity, nylon log muaj kev tsis zoo. Qhov no ua kom nrawm nrawm tus nqi nyob hauv ib puag ncig nrog qib siab ntawm cov khib nyiab, xws li cov chaw tsim khoom thiab cov phiaj xwm kev tsim kho.

 

III. Kev Hloov Kho Cov Lus Taw Qhia: Qhov Kev Ntsuas Kev Ntsuas thiab Kev Ntsuas Kev Tsim Kho

 

1. Txoj cai nyob rau sab nraum zoov zeb pob zeb teeb tsa pem teb
Lub teeb -} rau {{1} {{{{2} Cov Khoom Siv Hluav Taws Xob (xws li cov khoom siv sab nraum zoov (xws li cov khoom siv sab nraum zoov (xws li cov thawv tso tawm sab nraum zoov thiab cov kua dej).

 

Cov xwm txheej nyob rau qhov chaw ua haujlwm ntsiag to tsis yog qhov yuav tsum tau ua tiav thiab siv tau cov tsheb thauj mus los hauv kev siv tsheb thauj khoom (qhov twg cov thav duab log) txhua hnub).

 

2. Cov lus qhia kom tsis txhob muaj

Nqa cov twj paj nruag zoo thiab cov khoom tsis txaus ntseeg: xws li sab nraum zoov ntsuas ntsuas ntsuas thiab kev thauj khoom iav (kev co tau yooj yim tuaj yeem yooj yim);

 

Cov xwm txheej nrog cov chaw mos thiab cov khib nyiab: xws li cov chaw tsim khoom (nrog cov rebar thiab gravel rau hauv av) thiab cov khoom siv rhuav tshem (nrog cov thooj av hauv av);

 

Cov chaw kub heev: xws li thaj chaw suab puam nyob rau lub caij ntuj sov (qhov chaw nyob hauv av> 80℃tau yooj yim sab nraud (qhov twg kub sab nraum zoov (qhov twg kub.

 

3. Kev siv kho kom zoo

Xaiv cov neeg siv nylon nrog cov bearings: qhov no tiv thaiv cov xuab zeb thiab gravel los ntawm nkag mus rau cov kabmob, txo qis thiab hnav.

Kev tu thiab txij nkawm: siv lub siab - lub siab huab phom phom los tshem tawm cov khib nyiab los ntawm lub log thav duab thiab cov kis tau. Tshawb xyuas lub log tread ib hlis ib zaug rau cov kab nrib pleb thiab ntxuav cov khib nyiab pov tseg tam sim ntawd.

 

Siv cov kev poob siab: yog tias kev co kom txo qis yog yuav tsum tau (xws li sab nraum zoov Tool), nruab cov roj av poob siab {}}}} Cov khoom siv rau cushion tej pob. Hauv cov ntsiab lus, nylon casters yog "hnav - Tsis txhob txaus tab sis tsis xis nyob" ntawm sab nraum zoov cov plag tsev. Lawv tsim nyog rau lub teeb mus rau nruab nrab loads, tsis muaj qhov tsim nyog rau kev co lossis suab nrov, thiab cov xwm txheej uas yuav tsum tau tu ncua ib txwm. Yog tias cov teeb meem uas tsis cuam tshuam kev thaiv kev thaiv thiab kev co tau hais meej tshwj xeeb, lawv tuaj yeem zoo hloov kho rau kev siv sab nraum zoov. Yog tias qhov xwm txheej yuav tsum muaj kev tshem tawm poob siab, ntsiag to tsis kam, nws pom zoo los hloov lawv nrog cov roj hmab log lossis cuam tshuam} tsis kam hloov polyurethane log.
