Nyob rau hauv kev xyaum, kev puas tsuaj los yog tsis ua hauj lwm feem ntau yog tshwm sim los ntawm ib tug ua ke ntawm ntau yam tsis ua hauj lwm mechanisms.Qhov ua rau ntawm cov kabmob tsis ua haujlwm yuav yog vim kev txhim kho tsis raug lossis kev saib xyuas, tsis xws luag hauv kev tsim cov kabmob thiab nws cov khoom nyob ib puag ncig;Qee qhov xwm txheej, nws kuj yuav yog vim txo tus nqi lossis tsis ua tiav qhov kev kwv yees ua haujlwm tau zoo.

Suab nrov thiab kev vibration

Bearing swb.Ua rau cov kabmob slippage Yog tias lub load me me dhau lawm, lub torque hauv cov kabmob yuav me me dhau los ua rau cov khoom siv dov tig, ua rau cov khoom dov plam ntawm txoj kev sib tw.Yam tsawg kawg nkaus ntawm cov kabmob: pob bearing P / C = 0.01;Cov menyuam kabmob P / C = 0.02.Hauv kev teb rau qhov teeb meem no, kev ntsuas tau suav nrog kev siv axial preload (preload caij nplooj ntoos hlav-pob bearing);Thaum tsim nyog, yuav tsum tau ua ib qho kev xeem thauj khoom, tshwj xeeb tshaj yog rau cov menyuam bearings cylindrical, kom ntseeg tau tias cov kev sim ntsuas ze rau qhov kev ua haujlwm tiag tiag;Txhim kho lubrication Raws li qee qhov xwm txheej, ua kom lub lubrication tuaj yeem txo qis ib ntus (hauv qee qhov kev siv);siv cov bearings blackened, tab sis tsis txo suab nrov;xaiv bearings nrog qis load peev.

Kev puas tsuaj.Cov kabmob nto strain tshwm sim los ntawm cov txheej txheem kev teeb tsa yuav ua rau lub suab nrov thaum cov kabmob khiav thiab dhau los ua qhov pib tsis ua haujlwm ntxiv.Qhov teeb meem no feem ntau tshwm sim hauv cov kab sib cais sib cais.Txhawm rau tiv thaiv qhov tshwm sim ntawm cov teeb meem zoo li no, nws raug nquahu kom tsis txhob thawb hauv cylindrical roller bearing ncaj qha thaum lub sijhawm teeb tsa, tab sis maj mam tig thiab thawb rau hauv, uas tuaj yeem txo cov txheeb ze zawv zawg;nws tseem tuaj yeem ua rau lub tes tsho qhia, uas tuaj yeem zam qhov kev teeb tsa zoo.'s pob.Rau qhov sib sib zog nqus groove pob bearings, mounting quab yuam yog siv rau lub nplhaib nruj nreem, zam lub mounting quab yuam los ntawm cov khoom dov.

False Brinell indentation.Cov tsos mob ntawm qhov teeb meem yog hais tias lub raceway nto muaj indentations zoo ib yam li lub installation tsis tsim nyog, thiab muaj ntau yam thib ob indentations ib sab ntawm lub ntsiab indentation.Thiab tib qhov deb ntawm cov menyuam.Qhov no feem ntau yog vim kev vibration.Qhov laj thawj tseem ceeb yog tias lub cev muaj zog nyob hauv lub xeev zoo li qub rau lub sijhawm ntev lossis thaum lub sijhawm thauj mus los ntev, thiab lub sijhawm ntev-tsawg zaus micro-vibration ua rau fretting corrosion ntawm cov kabmob raceway.Kev tiv thaiv kev tiv thaiv yog tias kev kho ntawm lub cev muaj zog yuav tsum tau ua kom zoo dua ntxiv thaum lub cev muaj zog tau ntim rau hauv lub hoobkas.Rau cov motors uas tsis tau siv ntev, cov bearings yuav tsum tau cranked tsis tu ncua.

Nruab eccentric.Lub eccentric bearing installation yuav ua rau kom cov kabmob tiv thaiv kev ntxhov siab, thiab kuj yooj yim ua rau kev sib txhuam ntawm lub tawb thiab lub ferrule thiab cov menyuam thaum lub sijhawm ua haujlwm, ua rau lub suab nrov thiab kev co.Ua rau ntawm qhov teeb meem no muaj xws li khoov shafts, burrs ntawm lub ncej los yog ntawm lub xub pwg nyom ntawm cov kabmob vaj tse, threads ntawm lub ncej los yog locknuts uas tsis siab compress lub ntsej muag bearing, tsis zoo sib xws, thiab lwm yam. Yuav kom tiv thaiv tau qhov tshwm sim ntawm qhov teeb meem no. , nws tuaj yeem daws tau los ntawm kev txheeb xyuas qhov khiav tawm ntawm lub tog raj kheej thiab lub rooj zaum bearing, ua cov ncej thiab cov xov tib lub sijhawm, siv cov khoom siv high-precision ntsuas phoo, thiab siv cov cuab yeej nruab nrab.

Lub lubrication tsis zoo.Ntxiv nrog rau kev ua suab nrov, lubrication tsis zoo tuaj yeem ua rau kev sib tw.Xws li cov teebmeem ntawm lubrication tsis txaus, impurities thiab cov roj uas muaj hnub nyoog.Kev tiv thaiv kev tiv thaiv muaj xws li xaiv cov roj uas tsim nyog, xaiv cov kabmob uas tsim nyog, thiab tsim cov roj lubrication lub voj voog tsim nyog thiab tus nqi.

Axial ua si loj heev.Lub axial clearance ntawm qhov sib sib zog nqus groove pob bearings yog loj dua qhov radial clearance, txog 8 mus rau 10 zaug.Nyob rau hauv kev npaj ntawm ob qhov sib sib zog nqus groove pob bearings, lub caij nplooj ntoos hlav preload yog siv los txo cov suab nrov los ntawm kev tshem tawm thaum ntxov ntawm kev ua haujlwm;Nws yog txaus los xyuas kom meej tias 1 ~ 2 cov ntsiab lus dov tsis muaj kev ntxhov siab.Lub preload quab yuam yuav tsum ncav cuag 1-2% ntawm qhov ntsuas dynamic load Cr, thiab lub preload quab yuam yuav tsum tau kho kom tsim nyog tom qab qhov pib clearance hloov.
