Dab tsi yog cov kabmob sib xyaw
Cov kabmob uas muaj cov khoom sib txawv (hlau, yas, cov khoom siv lubricating) yog hu ua cov kabmob sib xyaw, uas yog lawv tus kheej cov kabmob, thiab cov kabmob sib xyaw, tseem hu ua bushings, pads lossis lub tes tsho bearings, feem ntau yog cylindrical thiab tsis muaj qhov txav.
Standard configurations muaj xws li cylindrical bearings rau radial loads, flange bearings rau radial thiab lub teeb axial loads, spacers thiab tig-over gaskets rau hnyav axial loads, thiab zawv zawg daim hlau ntawm ntau yam duab. Cov qauv tsim kev cai kuj muaj, suav nrog cov duab tshwj xeeb, nta (supp, qhov, notches, tabs, thiab lwm yam) thiab qhov ntau thiab tsawg.
Composite bearingsyog siv rau zawv zawg, rotating, oscillating los yog reciprocating motion. Daim ntawv thov Plain feem ntau yog siv los ua cov bearings, bearings gaskets, thiab hnav daim hlau. Cov zawv zawg qhov rooj feem ntau yog tiaj tus, tab sis kuj tuaj yeem ua cylindrical thiab ib txwm txav mus rau hauv txoj kab ncaj nraim, tsis yog kev sib hloov. Cov ntawv thov teb suav nrog lub ntsej muag cylindrical thiab ib lossis ob qho kev qhia ntawm kev mus ncig. Oscillating thiab reciprocating tsab ntawv tsa suab muaj feem xyuam rau qhov chaw tiaj tus lossis cylindrical taug kev hauv ob qho tib si.
Cov kabmob sib xyaw ua ke tuaj yeem ua tau zoo lossis sib cais pob tw (pob kabmob) rau kev txhim kho yooj yim. Kev sib piv cov kabmob rau qhov kev thov yog qhov tseem ceeb. Cov loads siab yuav tsum tau bearings nrog qhov chaw sib txuas ntxiv thiab muaj peev xwm nqa tau siab. Khoom lubricant bearings yog tsim los ua haujlwm ntawm qhov kub siab tshaj li cov roj lubricating thiab roj lubricated bearings. Kev siv kub-kub yuav tsum tau tshwj xeeb lubrication ntsuas kom txo cov cua sov tsim thiab kev sib txhuam.
Composite bearingsyog tsim nyob rau hauv cov qauv sib txawv. Kev xaiv ntawm cov khoom yog nyob ntawm qhov kev ua haujlwm thiab kev ua haujlwm ntawm kev ua haujlwm.
Hom kev sib txhuam ntawm cov khoom siv qis qis
Cov hlau sib xyaw bearings muaj cov hlau thim rov qab (feem ntau yog hlau lossis tooj liab) uas cov ntxeem tau tooj liab interlayer yog sintered, impregnated nrog PTFE thiab additives kom tau ib tug khiav nto nrog anti-kev sib txhuam thiab siab coj bearing zog. Cov kabmob no tuaj yeem ua haujlwm qhuav lossis lubricated sab nraud.
Composite bearings tseem tuaj yeem ua los ntawm cov yas engineering, uas muaj kev hnav zoo heev thiab tsis muaj kev sib txhuam, thiab siv dav hauv kev sib txhuam qhuav thiab lubrication kev ua haujlwm. Txhaj tshuaj molded, uas tuaj yeem tsim los ua yuav luag txhua yam thiab yog tsim los ntawm ntau hom resins sib xyaw nrog cov fibers reinforcing thiab cov khoom lubricants. Cov kabmob no muaj qhov zoo ntawm qhov ruaj khov, qis coefficient ntawm kev sib txhuam thiab zoo thermal conductivity.
Fiber-reinforced composite bearings yog lwm hom kev sib xyaw bearings, uas yog tsim los ntawm filament-qhov txhab, fiberglass-impregnated, epoxy hnav-resistant low-friction bearing linings thiab ntau yam backings. Qhov kev tsim kho no tso cai rau cov kabmob tuaj yeem tiv taus siab zoo li qub thiab cov khoom hnyav, thiab cov khoom siv inertness ua rau nws zoo tagnrho rau kev siv nyob rau hauv ib puag ncig corrosive.
Monometal, bimetal, thiab sintered tooj liab composite bearings yog tsim los siv rau hauv av thiab underwater kev lag luam daim ntaub ntawv, qhov uas lawv txav mus qeeb nyob rau hauv siab loads. Lubricant-impregnated khoom tooj liab bearings muab kev txij nkawm-dawb kev ua haujlwm nyob rau hauv high-temperature daim ntaub ntawv, thaum mono- thiab bimetal-based bearings yog tsim los rau lubrication daim ntaub ntawv.
Qhov txawv ntawmsib xyaw bearingsthiabdov thiab koob cov menyuam bearings
Muaj qhov sib txawv tseem ceeb ntawm kev sib xyaw thiab dov bearings, yog li lawv tsis hloov pauv.
1. Rolling bearings, vim lawv txoj kev tsim ntau yam sib xyaw, cov qauv tsim thiab kev teeb tsa zoo, feem ntau kim dua li cov kabmob sib xyaw.
2. Rolling bearings yog qhov tsim nyog rau cov ntawv thov uas xav tau txoj haujlwm ntawm cov ncej thiab / lossis kev sib txhuam qis heev.
3. Composite bearings, vim lawv qhov chaw sib cuag loj dua thiab hloov tau yooj yim, tuaj yeem muab cov kabmob muaj peev xwm ntau dua thiab ua rau muaj kev cuam tshuam rau cov loads siab thiab cov concentrated loads ntawm qhov kawg.
4. Composite bearings compensate rau misalignment zoo dua li ib co dov bearings kom txo cov kev cuam tshuam ntawm concentrated load thaum kawg.
5. Cov kabmob sib xyaw tau txais cov qauv tsim ultra-nyias ib leeg, uas tuaj yeem txo qhov loj ntawm lub plhaub, txuag chaw thiab qhov hnyav rau qhov loj.
6. Cov kabmob sib xyaw muaj zog tiv thaiv kev sib txuas lus, uas tuaj yeem ua rau lub neej ntev ntawm cov kabmob.
7. Cov kabmob sib xyaw yuav tsis raug puas tsuaj los ntawm kev hnav los ntawm kev zawv zawg ntawm cov khoom dov thaum khiav ntawm kev kub ceev thiab qis dhau, thiab muaj kev ua haujlwm zoo heev.
8. Muab piv nrog cov kabmob dov, cov kabmob sib xyaw tsis muaj qhov txav mus rau hauv, yog li lawv khiav ntau ntsiag to thiab yuav luag tsis muaj kev txwv ntawm kev ceev hauv qab lub tshuab lubricated kom zoo.
9. Kev teeb tsa ntawm cov kabmob sib xyaw yog qhov yooj yim, tsuas yog lub plhaub machining yuav tsum tau ua, thiab nws yuav tsis ua rau cov khoom puas tsuaj piv nrog cov kabmob dov.
10. Piv nrog cov qauv dov bearings, non-metallic composite bearings muaj zog corrosion kuj.
11. Cov kabmob sib xyaw tuaj yeem ua kom qhuav yam tsis muaj nqi ntxiv cov roj nplaum, cov roj nplaum thiab cov khoom siv poob qis thaum lub sijhawm tu.
12. Cov kabmob sib xyaw tuaj yeem ua haujlwm kom qhuav nyob rau hauv cov xwm txheej ntawm qhov kub thiab txias.
