Ob Chav Kab Cylindrical Cov Menyuam Bearings
Nta
Ob chav kab cylindrical cov menyuam bearings:
NN hom: lub nplhaib puab muaj tav, thiab lub nplhaib sab nrauv tsis muaj tav. Lub nplhaib sab nrauv thiab lub rooj sib dhos sab hauv tuaj yeem ntsia tau sib cais, uas tsis txwv qhov kev hloov ntawm axial ntawm tus ncej lossis lub tsev, thiab tsis tuaj yeem nqa lub axial load. Piv nrog rau ib kab cylindrical roller bearing ntawm tib lub radial loj, nws tuaj yeem tiv taus qhov hnyav dua radial. Cov qauv yog compact, lub deformation nyob rau hauv load yog me me, thiab nws yog tshwj xeeb tshaj yog haum rau kev txhawb nqa ntawm spindle ntawm lub tshuab cuab yeej.
Hom NN…K:
Cov qauv yog tib yam li NN hom, tab sis lub puab qhov ntawm cov kabmob yog tapered, uas yog yooj yim rau fine-tuning lub radial clearance ntawm cov kabmob thiab yooj yim rau kev sib dhos thiab disassembly. Hom kabmob no feem ntau yog siv nyob rau hauv lub ntsiab ncej ntawm lub tshuab cuab yeej thiab tau nruab rau ntawm cov ncej tapered. Lub radial clearance yog kho los ntawm tus nqi nias ntawm lub nplhaib puab.
Hom NNU, NNU…K:
Lub nplhaib sab nrauv muaj ribs thiab lub nplhaib puab tsis muaj tav. Muaj ob hom cylindrical qhov thiab conical qhov. Nws tsis txwv qhov axial txav ntawm lub ncej lossis vaj tse thiab tsis tuaj yeem nqa axial loads. Piv nrog rau ib kab cylindrical roller bearing ntawm tib lub radial loj, nws tuaj yeem tiv taus qhov hnyav dua radial.
Hom NNCF:
Lub nplhaib puab muaj peb tav thiab lub nplhaib sab nrauv muaj ib lub tav rau axial positioning nyob rau hauv ib qho kev taw qhia. Lub nplhaib sab nraud yog haum nrog lub nplhaib tuav ntawm sab nraud ntawm tus tav kom cov kabmob hauv ib thooj.
NCV Type:
Lub nplhaib puab muaj peb ribs, lub nplhaib sab nrauv tsis muaj tav, thiab muaj cov nplhaib nres ntawm ob sab los ua ib qho kev sib cais.
NWS:
Lub nplhaib puab muaj peb ribs, lub nplhaib sab nraud tsis muaj ribs, thiab muaj ib lub nplhaib xauv nruab nrab nyob rau hauv nruab nrab ntawm lub nplhaib sab nraud, uas dhau los ua ib qho kev sib cais. Cov ncej thiab cov kabmob lub rooj zaum tso cai rau qee qhov kev hloov pauv axial thiab tuaj yeem siv los ua cov kabmob dawb kawg.
Daim ntawv thov
Xws li bearings yog tsuas yog siv nyob rau hauv lub tshuab cuab tam spindles, internal combustion engine, roj turbines, reducers, loading thiab unloading machinery thiab ntau yam muaj machinery.
Qhov ntau thiab tsawg:
Ob chav kab cylindrical cov menyuam bearings:
Sab hauv txoj kab uas hla: 50mm ~ 1500mm
Sab nraud txoj kab uas hla: 80mm ~ 2300mm
Dav loj ntau yam: 23mm ~ 800mm
Kev kam rau siab: Cov khoom lag luam raug muaj qib zoo tib yam, qib P6, qib P5, thiab qib P4 cov khoom tuaj yeem ua tiav yog tias tus neeg siv muaj cov kev cai tshwj xeeb.
Radial clearance
Cov khoom txheem ntawm ob kab cylindrical cov menyuam kabmob muaj 1 txheej ntawm kev tshem tawm, thiab cylindrical bore bearings tuaj yeem muab 2 lossis 3 txheej ntawm kev tshem tawm.
Tapered bore bearings kuj muaj nrog 2 pawg ntawm kev tshem tawm.
Bearings nrog radial clearance loj los yog me dua tus qauv tus nqi kuj tuaj yeem tsim raws li cov neeg siv khoom xav tau.
tawb
Ob chav kab cylindrical cov menyuam bearings feem ntau siv tshuab tooj dag tawb, thiab qee zaum nylon tawb kuj muaj.
