Yuav Ua Li Cas Ntsuas Cov Menyuam Chain Elongation: Cov chains tsis yog "stretched" zoo li cov roj hmab band
Chain Elongation Feem ntau yog los ntawm Kev Sib Koom Tes
Tom qab cov hlua khi ua haujlwm rau lub sijhawm, nws qhov ntev tag nrho maj mam nce.
Feem ntau, cov saw tsis tas yuav ncab zoo li cov khoom siv elastic. Hloov chaw, elongation feem ntau yog tshwm sim los ntawm kev hnav ntawm qhov chaw sib cuag ntawm:
Pins
Bushings
Rollers
Raws li txhua txoj hlua sib koom ua ke tau ntsib me me ntawm kev hnav, qhov ua tau zoo ntawm txhua qhov txuas ntxiv me ntsis. Thaum qhov hnav no sib sau ntau qhov sib txuas, tag nrho cov saw ntev ntev ntev.
Kev nkag siab txog cov txheej txheem no yog qhov tseem ceeb vim tias tsuas yog hloov cov saw hlau yam tsis tau kuaj xyuas lub sprocket yuav tsis daws qhov teeb meem yog tias cov hniav sprocket twb hnav kom phim cov saw elongated.
Vim li cas Chain Elongation yuav tsum ntsuas hla ntau qhov chaw
Kev ntsuas tsuas yog ib qho saw hlau tuaj yeem yooj yim tsim cov txiaj ntsig tsis raug vim:
Caliper positioning yuam kev
Roller clearance
Localized hnav
Ib txoj kev ntsuas txhim khu kev qha ntau dua yog:
Ntxuav cov saw ua ntej kuaj.
Muab cov ntsuas ntsuas ncaj nraim rau ntawm qhov chaw tiaj tus.
Siv lub teeb nro kom tshem tawm slack.
Ntsuas hla ntau lub suab ntawm tus pin lossis cov ntsiab lus siv rau cov menyuam.
Siv cov saw hlau ntau dua txo qhov cuam tshuam ntawm tus kheej ntsuas qhov yuam kev thiab muab tus neeg sawv cev elongation tus nqi ntau dua.
Yuav ua li cas xam Chain Elongation Rate
Txoj kev suav yog:
Elongation Rate (%)=[(Measured Length − Nominal Length) ÷ Nominal Length] × 100%
Qhov twg:
n= tus lej ntsuas qhov ntsuas
p= txheem saw pitch
Nominal Ntev=n × p
Ntsuas Length=qhov ntsuas qhov deb L
Txoj kev ntsuas thiab cov ntsiab lus siv yuav tsum ua raws li cov chaw tsim khoom lag luam cov lus qhia kev saib xyuas. Cov kev ntsuas sib txawv yuav tsum tsis txhob sib xyaw, xws li sib piv cov qhov ntev ntawm sab hauv nrog rau sab nraud.
Thaum twg Yuav Tsum Tau Hloov Cov Roller Chain?
Qhov tso cai elongation txwv nyob ntawm:
Hom chains
Sprocket tus naj npawb
Kev khiav hauj lwm ceev
Load condition
Cov cai thov
Rau ntau tus qauv kev lag luam rau cov menyuam saw daim ntawv thov, cov chaw tsim khoom feem ntau pom zoo tshuaj xyuas thiab hloov kev txiav txim siab thaum elongation mus txog kwv yees li.1.5%–2%.
Txawm li cas los xij, cov ntawv thov sib txawv yuav xav tau cov kev txwv sib txawv:
Conveyor chains
Txuas chains
Lifting apps
Kev nyab xeeb- cov cuab yeej tseem ceeb
Cov txheej txheem hloov kho kom raug yuav tsum ua raws li cov khoom tsim khoom lossis cov khoom siv saw hlau cov lus qhia.
Ib qho kev txwv elongation yuav tsum tsis txhob siv rau txhua lub saw tsav.
Tshawb xyuas Sprockets thiab Kev puas tsuaj ntawm tus kheej ntawm tib lub sijhawm
Thaum cov saw elongation tshaj qhov txwv tau pom zoo, lub sprocket yuav tsum tau kuaj xyuas.
Tshawb xyuas:
Hook-zoo li tus sprocket hniav
Cov hniav loj
Cov hniav tsis sib xws
Cov saw nws tus kheej kuj yuav tsum tau soj ntsuam qhov txuas los ntawm qhov txuas rau:
Corrosion
Cov pob qij txha
Cov menyuam tawg
Tsis txawv txav tus pin txav
Cov saw hlau tawg
Ib txoj hlua nrog qhov nruab nrab elongation tau txais yuav tseem muaj qhov kev puas tsuaj loj hauv cheeb tsam thiab yuav tsum tsis txhob nyob twj ywm hauv kev pabcuam.
Yog vim li cas Lubrication txiav txim chains hnav tus nqi
Qhov tseem ceeb tshaj plaws lubrication cheeb tsam tsis yog sab nraud ntawm cov saw phaj. Lub ntsiab lus tseem ceeb ntawm lubrication yog qhov chaw txheeb ze ntawm:
Pin thiab bushing
Bushing thiab roller
Tsuas yog txau cov roj mus rau sab nraud ntawm cov saw hlau yuav tsis tso cai rau cov roj nplua nyeem nkag mus rau hauv qhov sib koom ua ke.
Qhov tseeb lubrication nyob ntawm:
Hom lubricant zoo
Kho roj qhov chaw xa khoom
Ntxuav tej yam kev mob
Nyob rau hauv ib puag ncig muaj plua plav, cov roj tuab ntau dhau tuaj yeem nyiam cov khoom abrasive thiab ua kom hnav. Lubrication txoj kev yuav tsum tau xaiv ib txwm raws li kev ua haujlwm tiag tiag.
Kev soj ntsuam kev sib txawv muaj kev ntseeg siab dua li ib qho -Tsev Sij Hawm
Ib qho kev ntsuas tsuas yog qhia txog qhov xwm txheej tam sim no. Kev taug qab tsis tu ncua muab kev txiav txim siab saib xyuas zoo dua.
Pom zoo xyaum:
Cov ntaub ntawv:
Tib saw seem
Tib tus naj npawb ntawm pitches
Tib txoj kev ntsuas
Hnub tshuaj xyuas
Lub sijhawm ua haujlwm
elongation feem pua
Ib qho kev nce ntxiv hauv elongation tus nqi yuav qhia tau tias:
Kev ua haujlwm dhau
Kev tsis ncaj ncees
Lubrication tsis ua hauj lwm
Sprocket kev puas tsuaj
Kev npaj hloov pauv feem ntau yog kev lag luam ntau dua li tos rau:
Saw dhia
Cov hniav hla
Kev npaj tsis tiav ntawm cov saw hlau
Reliable Roller Chain Hloov thiab Matching Solutions
Thaum txiav txim hloov chains, muab:
Ua kom tiav cov xov tooj
Tus naj npawb ntawm strands
Saw ntev
Cov ntawv txuas
Kev ua haujlwm ib puag ncig
Kev ntsuas ntsuas
Tianjin OuNaiDamuab kev txhawb nqa rau kev sib tw:
Cov menyuam chains
Txuas chains
Sprockets
Kev sib raug zoo ntawm cov saw hlau thiab sprocket yuav pab tiv thaiv kev hnav ntxov ntxov los ntawm kev hloov cov khoom siv tsis sib xws thiab txhim kho lub sijhawm ntev - kis tau tus mob.
