Installation thiab sealing:
Lub installation ntawm cov kabmob muaj qhov cuam tshuam zoo rau lub neej. Kev teeb tsa ntawm cov kabmob yuav tsum muaj kev sib raug zoo, cov khoom sib khi tiv thaiv kev nkag mus ntawm cov plua plav, cov khoom thiab dej, thiab kev ua haujlwm radial clearance yuav tsum tau kho kom haum.
Dynamic load:
Thaum cov hlau daig, txias dov hlau, thiab cov khoom txawv teb chaws nkag mus rau hauv yob, nws yuav ua rau 10 mus rau kaum tawm lub sij hawm cuam tshuam lub zog. Yog li ntawd, kev ua haujlwm ntawm lub tshuab dov yuav tsum tau ua raws li tus qauv txhawm rau tiv thaiv cov hlau daig thiab lwm yam tshwm sim kom tsis txhob muaj kev puas tsuaj thaum ntxov ntawm cov kabmob.
kub:
Yog tias qhov ntsuas kub ua haujlwm siab tshaj 120 degrees Celsius, qhov kub ntawm cov rollers thiab raceways yuav siab dua (kwv yees li 150 degrees Celsius), uas yuav siab tshaj qhov kub ntawm cov bearings, thiab qhov hardness thiab qhov tseeb ntawm cov kabmob yuav ua rau cov roj tsis ua haujlwm zoo. .
lubricating:
Lub lubrication tsis zoo yuav ua rau muaj kev sib txhuam ntau dhau thiab kub nce, uas yuav ua rau muaj kev puas tsuaj thaum ntxov rau cov kabmob.
Kev puas tsuaj ntxov ntxov rau cov kabmob tshwm sim los ntawm kev siv ntau yam lossis ib puag ncig yog qhov pov tseg zoo ntawm cov peev txheej. Kev siv lub neej ntev ntawm cov kabmob tuaj yeem hais tau tias muaj kev cuam tshuam tseem ceeb hauv kev txuag hluav taws xob, kev tiv thaiv ib puag ncig, thiab kev txuag nyiaj.
Kev tshuaj xyuas kev puas tsuaj ua rau cov kabmob loj loj
Thiab kev tiv thaiv lub neej ntev
A. Kev ua haujlwm tsis raug
Kev teeb tsa tsis raug, kev ua haujlwm lossis kev tshem tawm tuaj yeem ua rau deformation lossis tsis zoo ntawm lub tawb.
Kev ntsuas ceev faj: Siv cov khoom tsim nyog, kev teeb tsa thiab tshem tawm cov cuab yeej.
B. lubrication tsis txaus
Tsis txaus los yog tsis tsim nyog lubrication yuav ua rau cov khoom khawb los yog loj bearing deformation.
Kev tiv thaiv kev tiv thaiv: txhim kho lub lubrication system, rov ua dua lossis hloov cov roj nplaum tsis tu ncua thiab tsim nyog.
C. xeb thiab corrosion
Kev sib cuag nrog dej tuaj yeem ua rau xeb thiab xeb ntawm cov kabmob, thiab cov kabmob xeb tuaj yeem tev tawm thaum ua haujlwm.
Kev Tiv Thaiv Kev Tiv Thaiv: Tshawb xyuas lub foob tsis tu ncua kom ntseeg tau tias muaj kev sib khi zoo thiab khaws cov kabmob kom raug.
D. Tam sim no
Thaum lub bearing tig, energization yuav ua rau grooves los yog nicks. Thaum cov kabmob nyob ruaj ruaj, kev ua haujlwm tsis raug hluav taws xob tuaj yeem ua rau muaj kev kub nyhiab me.
Kev ntsuas ceev faj: Ua ntej vuam qhov chaw uas tsis yog cov kabmob, txo lossis zam dhau tam sim no los ntawm cov kabmob los ntawm kev sib txuas hauv av kom raug.
E. Cov khoom siv sab nraud
Kev sib kis ntawm cov khoom abrasive thiab kev nkag mus ntawm cov khib nyiab tuaj yeem ua rau hnav, puas thiab dents ntawm cov kabmob ua haujlwm.
Kev tiv thaiv kev tiv thaiv: tshem tawm cov khoom invading thiab cov khib nyiab, hloov cov roj nplua nyeem, xyuas lub kaw lus kaw.
F. Eccentricity
Eccentricity, qaij lossis load ntau dhau tuaj yeem ua rau geometric stress concentration lossis nto tev tawm.
Kev tiv thaiv kev ntsuas: precision machining ntawm cov rooj zaum thiab lub xub pwg nyom.
