Bearings yog cov khoom tseem ceeb hauv cov cuab yeej siv tshuab. Nws lub luag haujlwm tseem ceeb yog txhawm rau txhawb nqa lub tshuab tig lub cev kom txo tau qhov sib txhuam coefficient ntawm cov khoom siv thauj khoom thaum lub sijhawm sib kis ntawm cov khoom siv.
Bearings tau muab faib ua radial bearings thiab thrust bearings raws li qhov sib txawv load-nqa cov lus qhia los yog nominal contact angles.
Raws li hom dov cov ntsiab lus, lawv tau muab faib ua: pob bearings thiab cov menyuam bearings.
Raws li seb lawv puas tuaj yeem ua kom haum, lawv tau muab faib ua: tus kheej-aligning bearings thiab non-aligning bearings (rigid bearings).
Raws li tus naj npawb ntawm kab ntawm dov cov ntsiab lus, lawv tau muab faib ua: ib kab bearings, ob-kab bearings, thiab ntau kab bearings.
Raws li seb cov khoom puas tuaj yeem sib cais, lawv muab faib ua: sib cais bearings thiab tsis-separable bearings.
Kuj tseem muaj kev faib tawm raws li cov qauv tsim thiab qhov loj me.
Kab lus no feem ntau qhia cov yam ntxwv, qhov sib txawv thiab kev siv ntawm 14 hom bearings.
1 Angular contact pob bearings
Muaj lub kaum sab xis ntawm lub ferrule thiab lub pob. Lub kaum sab xis ntawm tus qauv yog 15 °, 30 ° thiab 40 °. Qhov loj dua lub kaum sab xis sib cuag, qhov ntau dua qhov axial load peev xwm. Qhov me me ntawm lub kaum sab xis sib cuag, qhov yooj yim rau kev sib hloov ceev. Ib kab kab bearings tuaj yeem dais radial load thiab unidirectional axial load. Structurely, ob kab ib leeg-kab angular hu rau pob bearings ua ke ntawm sab nraub qaum qhia lub nplhaib puab thiab sab nraud thiab tuaj yeem dais radial load thiab bidirectional axial load.
Lub hom phiaj tseem ceeb:
Ib kab: tshuab cuab tam spindle, lub cev muaj zog siab, roj turbine, centrifugal cais, me me tsheb pem hauv ntej log, sib txawv pinion ncej.
Ob chav kab: roj twj, Cov hauv paus hniav tshuab, cua compressors, ntau yam kev sib kis, roj txhaj twj, tshuab luam ntawv.
2 Aligning pob bearings
Ob chav kab ntawm cov pob steel, lub nplhaib sab nrauv yog ib hom kheej kheej kheej kheej, yog li nws tuaj yeem hloov kho qhov chaw nruab nrab tsis zoo los ntawm deflection lossis non-concentricity ntawm ncej lossis vaj tse. Lub tapered bore bearing tuaj yeem ntsia tau yooj yim ntawm tus ncej los ntawm kev siv cov fasteners. Feem ntau Dais radial load.
Kev siv tseem ceeb: woodworking machinery, textile machinery drive shafts, ntsug seated self-aligning bearings.
3 Spherical cov menyuam bearing
Hom kabmob no yog nruab nrog cov menyuam kheej kheej ntawm lub nplhaib sib tw kheej kheej thiab ob lub nplhaib sib tw sab hauv. Raws li cov qauv sib txawv, nws muab faib ua plaub hom: R, RH, RHA thiab SR. Txij li thaum lub arc nruab nrab ntawm lub nplhaib sab nrauv raceway yog Lub chaw bearing zoo ib yam thiab muaj kev ua haujlwm ntawm tus kheej, yog li nws tuaj yeem hloov kho qhov chaw nruab nrab tsis zoo los ntawm deflection lossis tsis yog concentricity ntawm lub ncej lossis vaj tse, thiab tuaj yeem tiv taus radial loads thiab bidirectional axial loads.
Lub ntsiab siv: papermaking machinery, txo lub zog, railway tsheb qag, dov zeb gearbox rooj, dov zeb rollers, crushers, vibrating screens, luam ntawv machinery, woodworking machinery, ntau yam muaj reducers, ntsug zaum spherical bearings.
4 Thrust spherical cov menyuam bearing
Lub spherical rollers nyob rau hauv hom kabmob no yog teem obliquely. Txij li thaum lub raceway nto ntawm lub rooj zaum lub nplhaib yog kheej kheej thiab muaj nws tus kheej-aligning zog, nws muaj peev xwm cia lub ncej qaij rau qee yam. Lub peev xwm axial load yog loj heev. Nws tuaj yeem dais ob peb axial loads tib lub sijhawm. Radial load, roj lubrication feem ntau yog siv thaum siv.
Kev siv tseem ceeb: hydraulic generators, ntsug motors, kiv cua shafts rau ships, reducers rau dov screws nyob rau hauv dov mills, ntauwd cranes, thee mills, extruders, thiab sib sau tshuab.
5 Tapered Cov Menyuam Bearings
Hom kabmob no yog nruab nrog truncated conical rollers. Cov rollers yog coj los ntawm cov tav loj ntawm lub nplhaib puab. Lawv yog tsim los kom cov apex ntawm conical nto ntawm lub puab nplhaib raceway nto, txheej nplhaib raceway nto thiab cov menyuam dov nto sib tshuam ntawm cov kab nruab nrab ntawm cov kabmob. Ntawm qhov taw tes. Ib-kab bearings tuaj yeem dais radial load thiab ib-txoj kev axial load, thaum ob-kab bearings tuaj yeem dais radial load thiab ob-txoj kev axial load, thiab yog tsim rau bearing hnyav loads thiab cuam tshuam loads.
Main siv: Tsheb: pem hauv ntej log, rear log, kis tau tus mob, sib txawv pinion shafts. Tshuab cuab tam spindles, kev tsim machinery, loj ua liaj ua teb machinery, railway tsheb iav txo cov cuab yeej, dov zeb yob caj dab thiab txo cov cuab yeej.
6 Deep Groove Pob Bearing
Structureally, txhua lub nplhaib ntawm ib tug sib sib zog nqus zawj pob bearing muaj ib tug nruam groove raceway nrog ib tug ntoo khaub lig-section kwv yees li ib feem peb ntawm lub equatorial ncig ntawm lub pob. Sib sib zog nqus groove pob bearings yog tsuas yog siv los dais radial loads thiab tuaj yeem dais qee qhov axial loads.
Thaum lub radial clearance ntawm cov kabmob nce, nws muaj cov yam ntxwv ntawm lub angular contact pob bearing thiab tuaj yeem tiv taus alternating axial loads hauv ob qho kev qhia. Piv nrog rau lwm hom bearings ntawm tib qhov loj, hom kabmob no muaj kev sib txhuam me me, kev txwv tsis pub ceev, thiab siab precision. Nws yog hom kabmob nyiam rau cov neeg siv thaum xaiv.
Main siv: tsheb, tsheb laij teb, tshuab cuab yeej, motors, twj tso kua mis, agricultural machinery, textile machinery, thiab lwm yam.
7 Thrust pob bearing
Nws muaj lub ntsej muag zoo li lub nplhaib sib tw nrog lub raceway thiab lub pob thiab lub tawb sib dhos. Lub nplhaib sib tw uas sib tw lub nplhaib yog hu ua lub nplhaib sib tw, thiab lub nplhaib sib tw uas sib tw lub plhaub yog hu ua lub nplhaib lub rooj. Ob txoj kev coj tus kheej sib tw rau lub zais zais ntawm lub nplhaib nruab nrab. Cov kabmob ib-txoj kev tuaj yeem dais ib-txoj kev axial load, thiab ob-txoj kev bearing tuaj yeem nqa tau ob-txoj kev axial load (tsis muaj peev xwm dais radial load).
Main siv: tsheb kauj vab pins, tshuab cuab tam spindles.
