Cov cuab yeej thiab kev siv cov ntaub ntawv sib txhuam (Part 1)
Cov khoom sib txhuam yog cov khoom siv hauv cov tshuab fais fab uas tso siab rau kev sib txhuam kom ua tiav braking thiab kis tau tus mob. Txhua yam khoom siv tshuab thiab ntau lub tsheb txav yuav tsum muaj cov khoom siv braking lossis kis tau tus mob, thiab cov ntaub ntawv sib txhuam yog cov khoom tseem ceeb ntawm cov khoom siv braking lossis kis tau tus mob, uas ua rau cov cuab yeej siv tshuab thiab ntau lub tsheb ua haujlwm zoo thiab ntseeg tau.
Raws li cov chaw ua haujlwm sib txawv, cov ntaub ntawv sib txhuam tuaj yeem muab faib ua cov ntaub ntawv sib txhuam qhuav thiab cov ntaub ntawv sib txhuam ntub. Raws li lub npe qhia, cov ntaub ntawv sib txhuam qhuav feem ntau yog siv rau hauv qhov chaw qhuav; Cov ntaub ntawv sib txhuam ntub dej xa mus rau cov ntaub ntawv sib txhuam uas nyob hauv lub xeev lubricated hauv ib puag ncig kaw. Cov khoom siv kev sib txhuam thaum ntxov feem ntau siv cov khoom sib txhuam qhuav. Nyob rau hauv xyoo tas los no, vim lawv cov kev ua tau zoo tshaj plaws ntawm kev ntseeg siab, kev nyab xeeb thiab lub neej, cov ntaub ntawv sib txhuam ntub dej tau tsim sai heev thiab tau siv dav hauv tsheb, siv tshuab, tshuab ua liaj ua teb thiab ntau yam kev siv xws li brakes, clutches thiab gearboxes ntawm ntau yam kev lag luam machinery. .
Tam sim no, muaj ntau yam kev faib tawm ntawm cov ntaub ntawv sib txhuam ntub dej, suav nrog cov ntaub ntawv sib txhuam cov ntaub ntawv, cov ntaub ntawv sib txhuam hlau sintered, cov ntaub ntawv sib txhuam carbon, cov ntaub ntawv sib txhuam graphite, cov ntaub ntawv sib txhuam ntawm cov roj hmab, thiab lwm yam., txhua qhov sib txhuam cov ntaub ntawv. nws muaj nws tus kheej functions thiab zoo. Xav txog yam xws li cov txheej txheem tsim khoom, cov nqi tsim khoom thiab kev pabcuam lub neej, cov ntaub ntawv sib txhuam ntawm cov ntawv muaj qhov zoo dua thiab tau siv dav. Nrog rau kev txhim kho txuas ntxiv ntawm nws cov qauv thiab cov txheej txheem tsim khoom, cov ntaub ntawv niaj hnub-raws li kev sib txhuam cov ntaub ntawv tau siv dav hauv cov brakes ntub, clutches thiab gearboxes ntawm ntau lub tsheb thiab kev tsim kho tshuab.
2. Cov khoom tseem ceeb ntawm cov ntaub ntawv sib txhuam cov ntaub ntawv
Cov ntaub ntawv sib txhuam raws li cov ntaub ntawv yog cov khoom siv nrog lub network zoo li cov qauv ntxeem tau, uas yog tsim los ntawm cov khoom xws li fibers thiab fillers, thiab yog sib koom ua ke los ntawm cov resin los ua cov qauv ntxeem tau. Cov qauv ntxeem tau no tuaj yeem khaws cov roj lubricating. Thaum cov ntaub ntawv-raws li kev sib txhuam yog koom nrog kev sib txhuam ob peb, nws yog compressed thiab deformed, thiab cov roj lubricating hauv cov khoom yog nyem rau saum npoo los tsim cov roj lubricating; thaum sib cais, cov ntaub ntawv-raws li kev sib txhuam cov ntaub ntawv yuav rov zoo dua thiab rov zoo dua. Cov pores uas twb muaj lawm thiab roj rov qab nqus rau hauv qhov pores.
