Qhov txawv ntawm Plain Bearing thiab Bushing yog dab tsi?
Aug 27, 2024
Plain bearings thiab bushings yog cov khoom siv tseem ceeb siv hauv ntau lub tshuab tshuab kom txo qis kev sib txhuam ntawm cov khoom txav. Txawm hais tias lawv yuav zoo li zoo sib xws, lawv muaj qhov sib txawv hauv lawv qhov tsim, kev ua haujlwm, thiab kev siv.
Plain bearings, tseem hu ua lub tes tsho bearings lossis phau ntawv xov xwm bearings, yog cov khoom siv yooj yim tsim los txhawb kev sib hloov lossis zawv zawg ncej. Lawv muaj lub tes tsho cylindrical uas haum nyob ib ncig ntawm lub ncej, muab lub ntsej muag du rau cov ncej kom tig los yog swb tawm tsam. Plain bearings feem ntau yog tsim los ntawm cov ntaub ntawv xws li tooj liab, tooj dag, hlau, los yog cov ntaub ntawv sib xyaw, thiab lawv cia siab rau ib txheej ntawm lubrication kom txo qis kev sib txhuam thiab hnav.
Cov yam ntxwv tseem ceeb:
Tsim thiab Qauv: Plain bearings feem ntau muaj tus qauv ncaj nraim, muaj lub tes tsho lossis bushing uas haum nyob ib ncig ntawm lub ncej. Lawv tsis muaj cov khoom dov zoo li cov pob lossis cov chais.
Lubrication: Lubrication yog qhov tseem ceeb rau kev ua haujlwm zoo ntawm cov bearings. Lawv xav tau cov roj nplua nyeem tas li txhawm rau txo kev sib txhuam thiab tiv thaiv kev sib cuag ntawm cov hlau-rau-hlau, uas tuaj yeem ua rau hnav thiab tsim kua muag.
Daim ntaub ntawv: Plain bearings yog dav siv nyob rau hauv daim ntawv thov uas siab precision tsis tseem ceeb tab sis kev ntseeg tau thiab yooj yim yog qhov tseem ceeb. Feem ntau siv xws li automotive engines, industrial machinery, thiab cov khoom siv hauv tsev.
Qhov zoo: Lawv muaj peev xwm thauj khoom zoo thiab tuaj yeem ua haujlwm hauv qhov chaw hnyav uas muaj kev sib kis yuav cuam tshuam rau lwm hom kabmob. Plain bearings kuj yog tus nqi-zoo thiab yooj yim los tswj.
Disadvantages: Lawv feem ntau muaj kev sib txhuam ntau dua piv rau dov cov kabmob thiab tej zaum yuav xav tau ntau lub lubrication thiab tu. Lawv kuj tsis tshua haum rau cov ntawv thov kev kub ceev vim muaj peev xwm ua kom sov.
Bushings
Bushings, tseem hu ua bush bearings, yog ib hom kev coj tus kheej uas ua haujlwm zoo sib xws tab sis feem ntau nrog cov ntawv thov tshwj xeeb. Bushings feem ntau yog me me thiab tsim kom haum rau hauv vaj tse lossis mounting uas txhawb nqa tig los yog zawv zawg ncej.
Cov yam ntxwv tseem ceeb:
Tsim thiab Qauv: Bushings feem ntau yog cylindrical tab sis tuaj yeem ua ntau yam duab thiab ntau thiab tsawg, suav nrog flanged lossis unflanged versions. Lawv feem ntau yog muab tso rau hauv ib lub vaj tsev los yog bracket thiab muab ib qho kev sib txhuam qis rau cov ncej.
Khoom siv: Bushings feem ntau yog tsim los ntawm cov ntaub ntawv xws li tooj liab, yas, lossis cov khoom sib xyaw, nyob ntawm daim ntawv thov. Yas lossis polymer bushings feem ntau yog siv rau cov ntawv thov uas tsis muaj kev sib txhuam thiab nws tus kheej-lubricating zog.
Daim ntaub ntawv: Bushings yog siv nyob rau hauv ntau yam kev siv, xws li tsheb ncua kev kawm ntawv, tshuab, thiab ntau yam khoom siv. Lawv feem ntau pom nyob rau hauv qhov chaw uas qhov chaw muaj tsawg lossis qhov chaw uas cov kabmob yuav tsum tau hloov tau yooj yim.
Qhov zoo: Bushings yog qhov zoo nyob rau hauv daim ntawv thov qhov chaw txwv lossis tshwj xeeb mounting yuav tsum muaj. Lawv kuj tuaj yeem tsim los ua tus kheej lubricating, txo cov kev xav tau ntawm kev saib xyuas.
Qhov tsis zoo: Thaum bushings muaj kev ua tau zoo rau ntau daim ntawv thov, lawv yuav tsis haum rau kev kub ceev lossis siab load yam tsis muaj lubrication zoo. Tsis tas li ntawd, lawv tuaj yeem ua tau tsawg dua nyob rau hauv qhov kub siab lossis qis qis piv rau lwm hom kabmob.
Cov ntsiab lus ntawm qhov sib txawv
Tsim: Plain bearings feem ntau loj dua thiab yooj yim dua hauv kev tsim, muab cov kabmob nto rau cov ncej. Bushings feem ntau me me thiab tsim kom haum nyob rau hauv ib lub vaj tsev los yog bracket.
Khoom siv thiab lubrication: Ob leeg tuaj yeem ua los ntawm cov khoom zoo sib xws, tab sis bushings feem ntau yog ua los ntawm cov yas los yog cov ntaub ntawv sib xyaw rau kev siv tshwj xeeb. Plain bearings feem ntau yuav tsum tau lubrication sab nraud, thaum bushings yuav yog tus kheej lubricating.
Daim ntaub ntawv: Plain bearings yog siv nyob rau hauv ntau yam kev siv, nrog rau cov uas yuav tsum tau muaj peev xwm load. Bushings feem ntau yog siv rau hauv daim ntawv thov nrog tshwj xeeb mounting xav tau los yog qhov chaw txwv.
