Yam dab tsi tshwm sim tshwj xeeb cuam tshuam rau kev poob siab nqus thiab load-bearre muaj peev xwm ntawm cov casers?

Qhov poob siab nqus thiab load-bearre muaj peev xwm ntawm cov casters yog cov khoom siv ua tau zoo, suav nrog cov khoom siv, cov qauv kev qhia tshwj xeeb, thiab kev ua haujlwm. Hauv qab no yog cov ncauj lus kom ntxaws tshuaj xyuas ntawm cov tshwj xeeb cuam tshuam:

Cov ntsiab lus tseem ceeb cuam tshuam rau kev nqus cov kev nqus kev chim siab
Kev nqus dej poob siab yog qhov tseem ceeb ntawm lub tawb muaj peev xwm rau cushion thiab nqus cov deeg. Nws feem ntau nyob ntawm cov elasticity ntawm cov khoom, cov txheej txheem cushioning tsim, thiab sib xyaw nrog hauv pem teb. Cov ntsiab lus tshwj xeeb muaj xws li:

1. Elasticity thiab Hardness Ntawm Lub Log Khoom
Elasticity: Ntau dua cov elasticity ntawm cov khoom (xws li roj hmab muaj roj hmab lossis roj av zoo dua thiab ua kom zoo dua nws cov nyhuv dosping. Hloov siab, cov ntaub ntawv khuam (xws li cam khwb cia hlau los yog hard nylon) tau yuav luag tsis muaj kev nqus kom haum.
Hardness: Lub log hardness (ntsuas hauv ntug dej A lossis Shore D) ncaj qha cuam tshuam rau kev nqus tau. Piv txwv li, mos polyurethane / roj hmab log nrog ntug dej hiav txwv thiab muaj zog nqus dej nrog ib tug ntawm 95 lossis siab dua muaj kev poob siab tsis zoo.

2. Cov log qauv tsim
Daim qauv sib xyaw: Siv "cov tub ntxhais ua haujlwm nyuaj + tsim qauv txheej txheem" ​​Tsim (piv txwv li cov steel tub ntxhais, nyuaj ntse qhwv hauv roj hmab). Cov txheej elaste txheej muab cov cushioning, thaum lub zog sab hauv cov qauv ruaj ntseg, txhim kho kev nqus khoom khov kho thaum tswj cov kabmob thauj khoom-muag.

Hollow / Honeycomb Tus qauv: Hollow Grooves lossis cov tswv cuab honeycomb-zoo li tsim hauv lub log lub cev kom nqus kev co los ntawm cov qauv kev lag luam ntawm qee lub log). Qhov no yog tshwj xeeb yog tsim nyog rau nruab nrab thiab lub teeb thauj khoom.
Log txoj kab uas hla thiab dav: loj dua los yog sib npaug nrog 100mm) tau yooj yim dua mus ua pob thiab khoob hauv av, txo cov pob. Dav log treads (log dav ntau dua los yog sib npaug nrog thaj chaw sib ze nrog hauv av, txo qis siab thiab tsis sib xws.

3. Cushinging tsim ntawm lub bracket thiab kev sib txuas qauv
Poob siab yuav nqus ua ke los ua ke: springs, roj hmab ntxhua khaub ncaws (xws li kev poob siab ntawm lub tawb kho mob ntawm lub tsheb sib tw. Smookness ntawm lub log qag thiab bearings: zoo-zoo pob bearings lossis cov menyuam cov kabmob tuaj yeem txo kev sib txhuam los ntawm kev sib txhuam thiab kev txhim kho kev poob siab ruaj khov.

4. Cov kev yoog raws rau cov xwm txheej hauv av
Ntxhib, potholed nthwv dej yuav tsum muaj cov zog cushioning (xws li huab cua cushioning ntawm pneumatic log); du surfaces feem ntau yog nyob ntawm elasticity ntawm lub log khoom (piv txwv, polyurethane lub log tuaj yeem muab kev nqus dej tsis zoo).

Cov Ntsiab Lus Tseem Ceeb cuam tshuam rau kev thauj khoom-cov kabmob muaj peev xwm
Ntsaws cov peev xwm yog lub peev xwm ntawm ib qho caster kom tiv thaiv ntev ntev loads yam tsis muaj kev ua tsis tiav (deformation lossis pob txha lov). Nws nyob ntawm cov khoom siv lub zog, cov khoom tsim-cov kabmob-cov kabmob tsim, thiab kev faib khoom. Cov ntsiab lus tshwj xeeb muaj xws li:

1. Lub zog Khoom Siv Zog thiab Hnav Kuj
Cov khoom siv tshuab hluav taws xob: cov ntaub ntawv xws li hlau (cam khwb cia hlau, hlau), High-zog bolyurethane yog qhov siab dua load-cov xeeb ntxwv muaj peev xwm ntau dua cov roj hmab muag lossis zoo tib yam.
Kev qaug zog tiv: cov khoom muaj peev xwm tiv thaiv kev laus thiab hnav nyob rau hauv cov roj hmab hnyav (piv txwv li, muaj cov xwm txheej zoo dua, hnyav-thauj-thauj cov xwm txheej).

2. Tus qauv zog ntawm lub log tub ntxhais tub ntxhais thiab lub log lub cev
Lub log cov khoom siv: cov hlau pob khoom hlau (hlau, cam khwb cia hlau txuas ntxiv (kylon)
Log lub log tuab thiab cov pob tw: cov tuab tuab lub log log thiab cov pob zeb sab hauv (xws li radial ribs), qhov ntau dua deformation tiv taus cov load txwv.

3. Load-beary tsim cov nkhaus thiab cov txuas
Cov Khoom Siv Bracket thiab cov tuab: Txias-rolled steel (tuab ntau dua los yog sib npaug ntawm cov hlau loj dua li cov hlau (qis dua lossis sib npaug. Lub zog ntawm lub vuam / riveting cov txheej txheem tseem ncaj qha cuam tshuam cov khoom muaj zog tag nrho.
Cov Kabmob Hom: Rau cov ntawv thov hnyav, cov menyuam yaus muaj peev xwm txo qis dua lossis sib npaug rau 100kg) kom tsis txhob muaj cov kabmob pob txha lov thiab ua tsis tiav.

4. Tus naj npawb ntawm cov log thiab load faib
Ntau lub log-kev sib txuas ua ke: nyob rau hauv tib lub nra, ntau dua cov khoom siv bears, thiab nws yog qhov tseem ceeb tshaj plaws kom tsis txhob muaj kev thauj khoom tsis sib xws).
Matching Log Thiaer taub mus rau thauj: Loj-diam log (ntau dua lossis sib npaug ntawm cov xeeb ntxwv log (tsawg dua los yog sib npaug ntawm 75 hli).

5. Kev Nyab Xeeb Qhov thiab Siv Tau
Muaj kev nyab xeeb txog kev nyab xeeb yuav tsum tau tso cai rau cov khoom thauj khoom tiag tiag (feem ntau 1.2-1.5 zaug tus ntaus nqi) kom tsis txhob muaj kev qaug zog los ntawm overload. Kev kub siab thiab cov av noo tuaj yeem txo cov khoom siv zog (piv txwv, roj hmab muag yooj yim ntawm cov khoom siv kub siab), yog li ib qho khoom siv tiv thaiv ib puag ncig), yog li cov khoom siv tiv thaiv ib puag ncig

Cov ntsiab lus: poob siab yog feem ntau cuam tshuam los ntawm cov khoom elasticity, thaum lub log tsheb cushioning yog nyob ntawm cov khoom siv lub zog, thiab thauj khoom ruaj khov. Qhov sib npaug ntawm ob qho yuav tsum tau ua ke nrog cov xwm txheej zoo nkauj, thiab cov khoom siv nyuaj + lub log uas tsim nyog) thiab ib puag ncig kev yoog.
