Bearing yog dab tsi?
Bearings yog cov khoom siv kho tshuab tsim los txhawb kev sib hloov shafts, txo kev sib txhuam, thiab nqa cov khoom thauj. Los ntawm kev txo qis kev sib txhuam ntawm cov khoom txav, bearings ua kom smoother thiab ua haujlwm zoo dua, txhim kho kev ua haujlwm thiab kev ua haujlwm ntev ntawm cov tshuab. Bearings muaj nyob rau hauv suav tsis txheeb daim ntaub ntawv, los ntawm automotive engines mus rau industrial machines.
Lo lus "kev coj tus kheej" yog los ntawm cov lus qhia "rau dais," xa mus rau lub tshuab uas ua rau ib feem los txhawb lwm tus. Daim ntawv yooj yim tshaj plaws ntawm cov kabmob muaj xws li cov kabmob uas zoo li tus lossis muab tso rau hauv ib qho kev tivthaiv, nrog rau ntau theem ntawm precision hais txog cov duab, qhov loj, roughness, thiab qhov chaw ntawm qhov chaw.
Muaj nuj nqi ntawm Bearings:
Txo kev sib txhuam: Bearings txo kev sib txhuam ntawm cov khoom txav, uas txhim kho kev ua haujlwm thiab kev ua haujlwm ntev ntawm cov tshuab.
Kev them nyiaj yug Load: Bearings txhawb nqa ob qho tib si radial (perpendicular rau lub ncej) thiab axial (piav mus rau lub ncej) loads, kom ruaj khov.
Txhim kho Precision: Los ntawm kev txo qis kev ua si thiab tswj kev sib raug zoo, bearings txhim kho qhov tseeb ntawm cov tshuab.
Cov khoom siv bearing:
Hlau: Cov khoom siv feem ntau vim nws lub zog thiab kav ntev.
Ceramics: Siv rau kev siv ceev ceev thiab ib puag ncig nrog qhov kub thiab txias.
Plastics: Haum rau lub teeb yuag thiab corrosive ib puag ncig.
Bearing Components:
Bearing Components removebg saib ua ntej
Inner Race (Inner Nplhaib)
Cov haiv neeg sab hauv, feem ntau hu ua lub nplhaib puab, yog ib feem ntawm cov kabmob uas txuas rau lub rotating ncej. Nws muaj ib tug du, precision-machined zawj qhov twg cov khoom dov txav. Raws li cov kabmob ua haujlwm, lub nplhaib no tig nrog rau cov ncej, tuav lub zog uas tau siv thaum siv.
Outer Race (Lub nplhaib sab nraud)
Nyob rau sab nraud yog cov haiv neeg sab nrauv, uas feem ntau nyob twj ywm hauv lub tsev lossis lub tshuab. Zoo li cov haiv neeg sab hauv, nws kuj muaj qhov zawj, hu ua raceway, qhov twg cov ntsiab lus dov zaum. Cov haiv neeg sab nrauv pab hloov cov khoom thauj los ntawm cov khoom sib hloov mus rau qhov seem ntawm cov qauv.
Rolling Elements
Cov no yog cov pob, chais, lossis rab koob uas zaum ntawm cov kev sib tw sab hauv thiab sab nrauv. Cov duab ntawm cov khoom no nyob ntawm seb hom kabmob. Pob bearings siv cov npas kheej kheej, thaum cov menyuam bearings siv lub tog raj kheej lossis tapered rollers. Cov ntsiab lus no yog dab tsi pab txo kev sib txhuam thiab tso cai rau kev sib hloov.
Cage (Retainer)
Lub tawb yog feem ntau saib tsis tau tab sis tseem ceeb ntawm cov kabmob. Nws pab kom cov dov cov ntsiab lus sib npaug sib npaug thaum lawv txav mus los, tiv thaiv lawv los ntawm kev sib koom ua ke thiab tswj kev ua haujlwm du. Cages yog tsim los ntawm cov ntaub ntawv xws li hlau lossis yas, nyob ntawm seb hom kabmob thiab nws qhov kev siv.
Seals thiab Shields
Cov no yog cov yam ntxwv tiv thaiv. Cov ntsaws ruaj ruaj yog tsim los kom tsis txhob muaj cov kab mob xws li av thiab noo noo tawm ntawm cov kabmob, thaum khaws lubrication hauv. Shields ua haujlwm zoo sib xws tab sis tso cai rau me ntsis kev ywj pheej ntawm kev txav mus los. Cov ntsaws ruaj ruaj feem ntau yog siv nyob rau hauv ib puag ncig hnyav, thaum cov ntaub thaiv npog siv qhov kev sib kis tsis tshua muaj kev txhawj xeeb.
Lubrication
Bearings xav tau lubrication kom ua haujlwm tau zoo. Txawm hais tias roj lossis roj, lubrication txo kev sib txhuam ntawm qhov txav thiab pab tiv thaiv kev hnav. Nws kuj pab kom txias cov kabmob, uas tuaj yeem yog qhov tseem ceeb hauv kev siv high-speed.
Kev sib tw
Txoj kev sib tw yog qhov zawj hauv cov kev sib tw sab hauv thiab sab nrauv uas cov khoom txav txav mus. Qhov saum npoo no yuav tsum raug tsim los ua kom ntseeg tau tias kev txav mus los thiab txawm tias faib cov khoom thauj.
