Kev sib piv ntawm cov pob bearings thiab cov menyuam bearings
Qhov txawv tseem ceeb ntawm Pob kabmobs thiab cov menyuam bearings yog cov duab thiab hom kev sib cuag ntawm cov khoom dov, uas cuam tshuam ncaj qha rau lawv cov kev ua tau zoo thiab cov xwm txheej ntawm daim ntawv thov.
Cov qauv thiab txoj cai ua haujlwm
Pob kabmob:
Cov khoom dov ntawm lub pob bearings yog spherical thiab qhov sib cuag nrog cov raceways yog point contact. Thaum lub load nce, qhov sib cuag yuav dhau los ua thaj chaw elliptical, uas ua rau cov pob bearings tsis tshua muaj kev sib txhuam thiab tsis tshua muaj cua sov thaum tig ntawm qhov ceev ceev, tsim nyog rau cov xwm txheej tig ceev ceev.
Cov khoom dov ntawm cov kabmob yog cylindrical lossis conical zoo li, thiab qhov sib cuag nrog cov raceways yog kab sib cuag. Thaj chaw sib cuag loj tuaj yeem faib cov khoom thauj ntau dua, yog li muaj peev xwm nqa tau ntau dua, tab sis kuj muaj kev sib txhuam ntau dua, tsim nyog rau cov khoom thauj hnyav tab sis qhov ceev tig qis.
Cov yam ntxwv ntawm kev ua tau zoo
Pob kabmob:
Qhov Zoo: Kev sib txhuam pib tsawg, kev sib txhuam ua haujlwm tsim nyog, muaj peev xwm tiv taus kev sib xyaw ua ke ntawm radial thiab axial, tsis hnov mob rau kev cuam tshuam ntawm lubrication, yooj yim pib ntawm qhov kub qis.
Qhov tsis zoo: Kev poob siab tsis zoo, qhov radial clearance loj, uas yuav ua rau muaj kev co thiab suab nrov ntau dua.
Cov menyuam bearing:
Qhov zoo: Lub peev xwm nqa tau zoo, kev ua haujlwm raug siab, cov qauv compact, tus nqi qis.
Qhov tsis zoo: tsis kam rau kev cuam tshuam, lub neej luv dua nyob rau hauv kev kub ceev thiab kev thauj khoom hnyav, kev sib xyaw ua ke ntawm cov nplhaib sab hauv thiab sab nraud, nyuaj rau nruab.
Cov xwm txheej ntawm daim ntawv thov
Cov kabmob pob:
Haum rau cov ntawv thov uas xav tau kev kub ceev, thauj khoom me me thiab kev lag luam zoo, xws li cov motors, kiv cua, thiab lwm yam.
Cov kabmob rau cov menyuam:
Haum rau cov ntawv thov nrog qhov ceev qis, cov khoom loj lossis cov khoom cuam tshuam, xws li cov tshuab hnyav, tsheb, kev thauj mus los ntawm tsheb ciav hlau, thiab lwm yam.
Uas muaj peev xwm nqa tau ntau dua, pob bearings lossis roller bearings？
Hais txog kev ua haujlwm ntawm lub nra hnyav, muaj qhov sib txawv tseem ceeb ntawm cov kabmob menyuam thiab cov kabmob pob. Cov kabmob menyuam, nrog lawv cov qauv ruaj khov uas muaj cov nplhaib sab hauv, cov nplhaib sab nraud, cov menyuam thiab cov tawb, qhia tau tias muaj peev xwm nqa tau zoo heev. Lawv ua haujlwm tau zoo tshwj xeeb hauv cov khoom siv radial siab thiab cov khoom siv radial sib dua mus rau nruab nrab, ua rau lawv yog qhov kev xaiv zoo tshaj plaws rau cov tshuab thiab khoom siv hnyav thiab hnyav heev, xws li cov tshuab hnyav, cov tshuab tsim kho thiab cov gearbox loj. Hauv kev sib piv, txawm hais tias cov kabmob pob muaj cov qauv yooj yim, qhov tseeb siab thiab kev sib txhuam tsawg, lawv lub peev xwm nqa tau qis dua me ntsis thiab lawv tsim nyog dua rau cov xwm txheej thauj khoom nruab nrab. Cov kabmob pob suav nrog ntau hom xws li cov kabmob pob sib sib zog nqus, cov kabmob pob sib cuag angular thiab cov kabmob pob sib dhos tus kheej, txhua tus tsim nyog rau cov khoom siv nrog qhov ceev sib txawv thiab qhov yuav tsum tau thauj khoom. Yog li ntawd, thaum xaiv hom kabmob, yuav tsum xav txog txhua yam raws li cov xwm txheej thauj khoom tshwj xeeb thiab ib puag ncig siv ntawm cov khoom siv tshuab. Cov kabmob menyuam tsim nyog dua rau kev tiv taus cov khoom siv radial loj dua thiab hnyav, thaum cov kabmob pob ua haujlwm tau zoo dua hauv cov khoom siv nruab nrab.
Cov txiaj ntsig thiab qhov tsis zoo ntawm cov menyuam bearings thiab pob bearings yog dab tsi?
Cov kabmob rau cov menyuam thiab cov kabmob pob txhua tus muaj lawv tus kheej qhov zoo thiab qhov tsis zoo. Cov kabmob rau cov menyuam muaj thaj chaw sib cuag loj nrog cov kab sib tw vim tias cov khoom dov yog cylindrical, uas ua rau lawv tuaj yeem tiv taus cov khoom thauj radial loj. Lawv kuj muaj kev ruaj khov zoo thiab ruaj khov thaum lub sijhawm ua haujlwm ceev ceev, tab sis lawv cov coefficient sib txhuam yog qhov loj heev. Cov khoom dov ntawm cov kabmob pob yog spherical, nrog cov coefficient sib txhuam qis thiab kev ua haujlwm yooj ywm. Lawv tsim nyog rau cov ntawv thov uas xav tau kev ua haujlwm siab thiab kev ua haujlwm ceev ceev. Txawm li cas los xij, thaum raug cov khoom hnyav, lawv yuav ua rau muaj kev sib cuag tsis ruaj khov vim yog qhov cuam tshuam ntawm lub zog centrifugal. Hom kabmob twg xaiv tshwj xeeb tseem nyob ntawm koj qhov xwm txheej thov thiab cov kev xav tau tiag tiag.
Qhov twg zoo dua rau kev ua haujlwm ceev ceev, cov menyuam bearings lossis pob bearings?
Cov kabmob uas dov feem ntau yog qhov tsim nyog dua rau kev ua haujlwm ceev ceev. Cov kabmob uas dov muaj cov khoom siv dov cylindrical, uas ua rau thaj chaw sib cuag loj nrog cov raceways. Lawv tuaj yeem tiv taus cov khoom hnyav thiab muaj kev ruaj khov zoo thiab ruaj khov thaum lub sijhawm ua haujlwm ceev ceev. Cov khoom siv dov ntawm cov kabmob pob yog spherical. Txawm hais tias qhov coefficient ntawm kev sib txhuam me me, thaum lub sijhawm ua haujlwm ceev ceev, kev sib cuag ntawm cov pob thiab cov raceways yuav tsis ruaj khov vim yog qhov cuam tshuam ntawm lub zog centrifugal. Tau kawg, qhov kev xaiv tshwj xeeb ntawm cov kabmob twg yuav siv tseem yuav tsum tau txiav txim siab raws li koj qhov xwm txheej siv tiag tiag thiab cov kev xav tau.
