Yuav xaiv hom kabmob li cas

Thaum xaiv hom kabmob, nws yog ib qho tseem ceeb kom nkag siab zoo txog cov xwm txheej uas yuav siv tau.

Xaiv txoj kev:

1) Qhov chaw teeb tsa cov kabmob tuaj yeem nkag mus rau hauv qhov chaw teeb tsa ntawm cov kabmob vim tias qhov nruj thiab lub zog ntawm cov ncej tau them nyiaj rau thaum tsim cov ncej, yog li txoj kab uas hla feem ntau txiav txim siab ua ntej, uas yog, sab hauv. txoj kab uas hla ntawm cov kabmob.

Txawm li cas los xij, dov bearings tuaj nyob rau hauv ntau yam loj series thiab hom, thiab hom kabmob uas haum tshaj plaws yuav tsum tau xaiv los ntawm lawv.

 

2) Qhov luaj li cas, kev taw qhia thiab qhov xwm txheej ntawm cov kabmob load [lub peev xwm ntawm cov kabmob yog qhia los ntawm qhov yooj yim rated load, thiab nws cov nqi muaj nyob rau hauv cov kabmob loj lub rooj] Cov kabmob load yog qhov sib txawv, xws li qhov loj me. lub load, txawm hais tias tsuas muaj ib tug radial load, seb lub axial load yog unidirectional los yog bidirectional, lub degree ntawm kev co los yog poob siab, thiab lwm yam.

 

Feem ntau, radial load peev xwm ntawm bearings nrog tib bore nce nyob rau hauv cov nram no kev txiav txim: sib sib zog nqus groove pob bearings < angular hu pob bearings < cylindrical roller bearings < tapered roller bearings < spherical roller bearings .

 

3) Hom kabmob uas nws qhov kev sib hloov ceev tuaj yeem hloov mus rau qhov kev sib hloov ceev [qhov txwv tus nqi ntawm cov kabmob ceev yog qhia los ntawm qhov txwv ceev, thiab nws cov nqi muaj nyob rau hauv cov kabmob loj lub rooj] Qhov kawg ceev ntawm cov kabmob tsis yog tsuas yog coj los ntawm hom kabmob, tab sis kuj txwv rau cov kabmob loj, hom tawb, qib raug, thauj khoom thiab cov txheej txheem lubrication, thiab lwm yam, yog li cov khoom no yuav tsum tau txiav txim siab thaum xaiv.

 

Feem ntau ntawm cov bearings hauv qab no yog siv rau kev sib hloov ceev:

Sib sib zog nqus groove pob bearings, angular contact pob bearings, cylindrical cov menyuam bearings

 

4) Kev sib hloov qhov tseeb: Hom kabmob uas yuav tsum tau muaj kev sib hloov qhov tseeb Tshuab cuab yeej spindle, roj turbine thiab tswj lub tshuab yuav tsum tau siv cov kev sib hloov siab, kev kub ceev thiab kev sib txhuam qis, yog li cov bearings nrog qib 5 raug lossis ntau dua yuav tsum tau siv.

 

Cov bearings hauv qab no feem ntau yog siv:

Sib sib zog nqus groove pob bearings, angular contact pob bearings,cylindrical cov menyuam bearings

 

5) Bearing hom uas nws rigidity ua tau raws li qhov rigidity yuav tsum tau rau cov neeg kho tshuab shafting Nyob rau hauv qhov chaw xws li tshuab cuab tam spindles thiab tsheb zaum kawg theem txo cov cuab yeej, nws yog tsim nyog los txhim kho lub rigidity ntawm ncej thiab rigidity ntawm cov kabmob.

 

Lub deformation ntawm cov menyuam bearings yog tsawg dua li ntawm pob bearings.

 

Siv preload (tsis zoo tshem tawm) rau cov kabmob tuaj yeem txhim kho qhov nruj. Txoj kev no yog tsim rau angular contact pob bearings thiab tapered roller bearings.

 

6) Txheeb xyuas qhov sib txheeb qaij nruab nrab ntawm lub nplhaib puab thiab lub nplhaib sab nraud ntawm cov kabmob (xws li lub deflection ntawm lub ncej los ntawm kev thauj khoom, qhov tsis zoo ntawm cov ncej thiab lub plhaub lossis qhov yuam kev ntawm kev teeb tsa), thiab xaiv hom bearing uas tuaj yeem hloov kho raws li kev siv. Yog hais tias tus txheeb ze inclination ntawm lub nplhaib puab mus rau lub nplhaib sab nraud loj heev, cov kabmob yuav raug puas vim lub load sab hauv. Yog li ntawd, ib hom kabmob uas tuaj yeem tiv taus qhov qaij no yuav tsum tau xaiv.

 

Feem ntau, qhov tso cai qaij lub kaum sab xis (los yog lub kaum sab xis) yog nce hauv qhov kev txiav txim hauv qab no:

Cylindrical cov menyuam bearings, tapered menyuam bearings, sib sib zog nqus groove pob bearings (angular hu pob bearings), kheej kheej cov menyuam (pob) bearings

 

7) Thaum lub sij hawm sib dhos thiab disassembly xws li installation thiab disassembly lub sij hawm soj ntsuam thiab sib dhos thiab disassembly txoj kev yog nquag, nws yog yooj yim dua los siv cylindrical roller bearings, koob rau cov menyuam bearings thiab tapered menyuam bearings uas yuav raug cais tawm ntawm lub nplhaib puab thiab lub nplhaib sab nrauv.

 

Spherical ball bearings thiab spherical roller bearings nrog tapered bore tau yooj yim sib dhos thiab disassembled los ntawm kev siv cov fasteners lossis lub tes tsho tshem tawm.
