Tsheb bearings hom

Rolling bearings yog qhov tseem ceeb ntawm cov khoom siv hauv ntau lub tshuab, ua kom muaj zog thiab ua haujlwm zoo thiab txo kev sib txhuam. Muaj ntau ntau hom dov bearings, txhua tus tsim los rau kev siv tshwj xeeb. Nyob rau hauv no blog ncej, peb yuav piav qhia txog ib co ntawm cov feem ntau dov bearings, nrog rau cov pob bearings thiab cov menyuam bearings, qhia lawv hom thiab lawv muaj peev xwm nyob rau hauv cov nqe lus ntawm quab yuam, ceev, thiab load.

Rolling bearing yog cov cuab yeej siv tshuab uas muaj lub nplhaib sab hauv, lub nplhaib sab nraud, cov khoom dov (pob lossis cov menyuam), thiab lub tawb. Lawv yog siv los tiv thaiv radial thiab / lossis axial loads, pab txhawb kev sib hloov los yog tawm suab, thiab txo kev sib txhuam ntawm cov khoom txav.

Axial Load vs Radial Load

Lub ntsiab lus tseem ceeb ntawm kev sib piv ntawm ntau hom bearings yog lawv cov load- nqa peev xwm. Lub load yog hais txog lub zog siv rau cov kabmob. Cov loads no tuaj yeem yog radial lossis axial. Radial load yog ib qho load thov perpendicular mus rau lub ncej, thaum lub axial load yog ib tug load thov nyob rau hauv tib txoj kev raws lub ncej. Ib qho kev sib xyaw ua ke yog ib qho kev thauj khoom uas siv ob qho tib si radial thiab axial rog rau cov kabmob ib txhij. Cov kabmob sib txawv muaj qhov sib txawv ntawm qhov sib txawv - nqa lub peev xwm.

Pob Bearings vs. Cov Menyuam Bearings

Pob bearings thiab cov menyuam bearings yog ob hom sib txawv ntawm dov bearings, nrog rau qhov sib txawv tseem ceeb hauv lawv cov qauv tsim thiab kev ua haujlwm. Pob bearings tsav kev txav los ntawm dov steel pob ntawm sab hauv thiab sab nrauv raceways. Lawv muaj kev sib txhuam qis thiab zoo heev - kev ua haujlwm ceev. Thaum lub pob bearings ua tau zoo nyob rau hauv siab - daim ntawv thov ceev, cov menyuam bearings yog qhov zoo dua rau cov dej num hnyav -. Cov menyuam bearings siv cylindrical los yog tapered rollers los nqa loads. Vim qhov chaw sib cuag loj dua ntawm cov khoom dov, cov menyuam bearings muaj kev nruj dua, ruaj khov, thiab thauj khoom- nqa lub peev xwm dua li pob bearings.

Pob bearings

Sib sib zog nqus groove pob bearings: Sib sib zog nqus groove pob bearings yog hom pob bearing feem ntau. Lawv muaj qhov sib sib zog nqus raceway grooves thiab tuaj yeem tiv taus radial thiab axial loads. Lawv cov yam ntxwv torque qis ua rau lawv zoo tagnrho rau kev siv siab - ceev. Sib sib zog nqus groove pob bearings yog ib qho yooj yim los tswj thiab tsis tshua muaj kev cuam tshuam rau kev ua haujlwm, ua rau lawv haum rau ntau yam kev siv.

Tus kheej-aligning pob bearings: Nws tus kheej-aligning pob bearings muaj ob kab ntawm cov npas uas txav raws li kev taw qhia ntawm lub tawb thiab muaj ob - kab hauv lub nplhaib sab hauv. Vim yog lawv cov qauv tshwj xeeb, cov kabmob no tuaj yeem ua rau muaj qhov tsis sib xws ntawm cov ncej thiab cov kabmob vaj tse, ua rau lawv tsim nyog rau kev siv qhov twg ncej deflection lossis misalignment yuav tshwm sim. Lawv muaj peev xwm load radial zoo thiab feem ntau siv hauv nruab nrab - daim ntawv thov ceev.

Angular contact pob bearings: Vim lawv cov qauv tshwj xeeb, angular contact pob bearings tuaj yeem tiv taus cov khoom sib xyaw. Muaj qhov sib txawv txav ntawm qhov sib tw sab hauv thiab sab nrauv raws cov kabmob axis. Raws li lub kaum sab xis ntawm kev sib cuag (lub kaum sab xis ntawm txoj kab sib txuas ntawm lub pob thiab qhov chaw sib tw hauv lub dav hlau radial thiab ib txoj kab ncaj nraim rau ntawm cov kabmob axis) nce, axial load peev kuj nce. Qhov kev tsim no tso cai rau lawv tiv taus siab axial loads thaum tseem muaj peev xwm radial zoo.

Thrust pob bearings: Thrust pob bearings yog tsim los tiv thaiv axial loads nkaus xwb thiab yuav tsum tsis txhob muaj radial loads. Lawv muaj nyob rau hauv unidirectional thiab ob - qauv kev taw qhia. Tus qauv tsim unidirectional muaj ob lub grooved washers (shaft washer thiab vaj tsev ntxhua khaub ncaws) nrog cov khoom dov (pob) nyob nruab nrab ntawm lawv. Ib qho kev qhia ob - qauv tsim muaj peb lub tshuab ntxhua khaub ncaws thiab ob lub pob tawb sib dhos, sib cais los ntawm lub tshuab ntxhua khaub ncaws. Thrust pob bearings yog ib qho yooj yim rau disassemble thiab sib hloov, ua rau lawv zoo tagnrho rau tsawg- daim ntawv thov ceev.

Cov menyuam bearings

Tapered roller bearings: Tapered cov menyuam bearings tuaj yeem tiv taus unidirectional ua ke loads. Lawv tapered thiab khob-zoo li tus raceways zoo kis radial thiab axial rog. Tapered roller bearings tuaj yeem muab faib ua ob-kab lossis plaub- kab teeb tsa, ua rau lawv tuaj yeem tiv thaiv ob txoj kev sib xyaw ua ke. Tapered roller bearings yog qhov zoo tshaj plaws rau nruab nrab -kev sib xyaw ua ke ntawm cov ntawv thov ceev.

Spherical roller bearings: Spherical roller bearings yog tsim los tiv taus cov radial loj thiab nruab nrab axial loads. Lawv cov qauv tsim zoo ib yam li ntawm tus kheej -aligning pob bearings, tab sis lawv siv spherical rollers li dov cov ntsiab lus. Qhov no tso cai rau lawv los them nyiaj rau misalignment. Spherical roller bearings muaj lub thoob - zoo li lub nplhaib sab nraud thiab ob kab ntawm cov menyuam, thiab tuaj yeem qhib lossis kaw. Spherical roller bearings ua tau zoo heev hauv kev siv nrog kev kub ceev, hnyav hnyav, thiab kev cuam tshuam.

Cylindrical roller bearings: Cylindrical roller bearings muaj peev xwm loj heev radial load thiab nruab nrab axial load peev xwm, nrog rau cov peev txheej tshwj xeeb nyob ntawm lawv cov qauv. Lawv muaj cov cylindrical rollers thiab tsim nyog rau cov ntawv thov uas tiv taus siab radial rog thiab kev kub ceev, thaum tseem muaj peev xwm tiv taus qhov cuam tshuam.

Koob cov menyuam bearings: Koob cov menyuam bearings siv cylindrical rollers, uas ua rau lub compact qauv thiab siab load- nqa peev xwm. Lawv yog tshwj xeeb tshaj yog haum rau daim ntaub ntawv uas txwv radial qhov chaw thiab siab radial load yuav tsum, tab sis tsis rau axial loads. Qhov ntev ntawm rab koob rau cov menyuam yog ob peb zaug nws txoj kab uas hla, thiab hauv qee qhov kev tsim, nws tuaj yeem ncav cuag 10 npaug ntawm txoj kab uas hla. Koob cov menyuam bearings yog qhov zoo tshaj plaws haum rau cov ntawv thov nrog qhov chaw txwv thiab cov khoom siv radial siab.

Cov saum toj no yog cov lus qhia yooj yim rau qee qhov feem ntau siv bearings. Kev nkag siab txog ntau hom bearings thiab lawv lub peev xwm nyob rau hauv cov nqe lus ntawm quab yuam, ceev, thiab load pab nyob rau hauv xaiv cov bearings haum rau ib tug tshwj xeeb daim ntawv thov. Los ntawm kev xav txog cov xwm txheej no, engineers thiab designers tuaj yeem xyuas kom meej tias lawv cov tshuab thiab cov tshuab ua tiav kev ua haujlwm zoo, ua haujlwm ntev, thiab ua haujlwm tau zoo.
