Dab tsi yog cov txheej txheem txhawb nqa ntawm crankshaft
Mar 02, 2023| Cov txheej txheem txhawb nqa ntawm lub crankshaft muaj xws li zawv zawg bearing thiab dov bearing.
Sliding bearing: Lub crankshaft thiab bearing nto yog nyob rau hauv zawv zawg sib cuag thiab lubricated nrog lubricating roj zaj duab xis. Qhov zoo ntawm zawv zawg bearings yog cov qauv yooj yim, tsis tshua muaj nqi tsim khoom, tab sis kev sib txhuam loj loj thiab yooj yim los ua kom sov. Yog li ntawd, lawv tsim nyog rau cov tshuab qis thiab nruab nrab.
Rolling bearing: Lub crankshaft thiab bearing nto yog nyob rau hauv dov kev sib cuag nrog cov khoom los yog chais, thiab lubricated nrog ib tug lubricating roj zaj duab xis. Nrog tsis muaj kev sib txhuam poob, nws yog tsim rau high-speed engine. Qhov tsis zoo ntawm dov bearings yog cov qauv tsim thiab cov nqi tsim khoom siab.
Zuag qhia tag nrho, zawv zawg bearings yog tsim rau qis thiab nruab nrab ceev cav, thaum dov bearings yog haum rau kev kub ceev cav.
Cov kev txhawb nqa ntawm lub cav crankshaft feem ntau muab faib ua cov hauv qab no:
Kev them nyiaj yug zawv zawg: Lub cav crankshaft feem ntau yog txhawb nqa los ntawm zawv zawg bearings, uas txhawb kev txav ntawm lub crankshaft los ntawm cov yeeb yaj kiab ntawm cov roj lubricating. zawv zawg bearings muaj qhov zoo ntawm kev hnav tsis kam thiab muaj peev xwm loj, tab sis lawv nquag muaj teeb meem xws li lubrication tsis zoo thiab hnav nyob rau hauv high-speed, high-temperature, thiab siab load.
Rolling bearing kev them nyiaj yug: Lub cav crankshaft tseem tuaj yeem txhawb nqa los ntawm cov kabmob dov, uas txhawb kev txav ntawm lub crankshaft los ntawm dov cov ntsiab lus xws li cov khoom thiab cov menyuam. Rolling bearings muaj qhov zoo ntawm cov kabmob loj thiab lub neej ua haujlwm ntev, tab sis lawv cov nqi tsim khoom yog siab thiab lawv lub suab nrov.
Hydrostatic bearing: Hydrostatic bearing yog ib tug high-precision, high-ceev crankshaft bearing txoj kev uas txhawb lub zog ntawm crankshaft los ntawm kev tsim siab nyob rau hauv lub bearings nrog high-pressure kua. Hydrostatic bearings muaj qhov zoo ntawm cov kabmob loj, lub neej ua haujlwm ntev, thiab tsis muaj kev sib txhuam, tab sis lawv cov nqi tsim khoom thiab kev saib xyuas yog siab.
Magnetic suspension bearing: Magnetic suspension bearing yog ib txoj kev siv tshuab crankshaft uas txhawb nqa lub zog ntawm crankshaft los ntawm electromagnetic quab yuam. Nws muaj qhov zoo ntawm kev tsis sib cuag, tsis muaj kev sib txhuam, thiab kev ua haujlwm zoo, tab sis nws cov nqi tsim khoom thiab kev saib xyuas yog qhov siab heev, thiab nws daim ntawv thov tam sim no kuj tsis tshua muaj.
