1. Kev faib tawm los ntawm Load Direction
Radial (cov ntawv xov xwm) zawv zawg bearings: Dais radial loads thiab yog hom ntau tshaj plaws, siv nyob rau hauv lub ntsiab bearings ntawm turbines thiab generators.
Thrust (axial) zawv zawg bearings: Dais axial loads thiab yog siv los tso rau qhov chaw axial ntawm rotating shafts, xws li thrust dab tshos txhawb nqa hauv cov twj loj.
Radial-thrust ua ke bearings: Dais ob radial thiab axial ua ke loads ib txhij.
2. Kev faib tawm los ntawm Lubrication Condition
Hydrodynamic lubrication bearings: Cia siab rau lub twj tso kua mis uas tsim los ntawm cov ntawv xov xwm rotating kom tuaj yeem tsim cov roj yeeb yaj kiab hauv cov kab sib txawv - zoo li qhov sib txawv. Tsis xav tau lub twj tso kua mis sab nraud, haum rau siab - nrawm nrawm- lub xeev.
Hydrostatic lubrication bearings: Siab- roj siab yog muab los ntawm ib qho kev hydraulic sab nraud kom yuam ua cov load- bearing roj zaj duab xis. Lawv tuaj yeem dais qhov hnyav tsis hais qhov nrawm, haum rau qis - nrawm hnyav- daim ntawv thov lossis cov xwm txheej uas xav tau siab heev.
Tus kheej -lubricating (roj-dawb) bearings: Cov khoom siv bearing nws tus kheej muaj kev tiv thaiv kev sib txhuam (xws li tooj liab alloys embedded nrog cov roj lubricants) thiab tuaj yeem ua haujlwm nyob rau hauv cov xwm txheej tsis muaj roj lossis nrog ciam lubrication.
3. Kev faib tawm los ntawm Cov Qauv Txheej Txheem
Integral zawv zawg bearings (bushings): Qhov yooj yim tshaj plaws cylindrical bearings, ntsia hauv tsev los ntawm nias.
Daim ntawv thov: Tsawg-ceev, lub teeb- thauj khoom, lossis cov xwm txheej tsis sib xws, xws li me me - kawg bushings ntawm txuas rods.
Split zawv zawg bearings: Muaj cov kabmob vaj tse, cov kabmob cap, thiab lub plhaub sab sauv thiab sab qis, txuas nrog bolts raws li qhov sib cais.
Qhov zoo: Ib qho yooj yim installation thiab tshem tawm kev hloov kho, yooj yim rau kev txij nkawm. Lawv yog cov kev xaiv tseem ceeb hauv cov khoom nruab nrab thiab loj, xws li crankshaft bearings.
Tilting pad bearings: Muaj ntau yam ntaub ntawv ywj pheej uas tuaj yeem hloov pauv kom haum rau kev hloov pauv hauv kev thauj khoom thiab ceev.
Qhov zoo: Muaj zog tiv thaiv cov roj zaj duab xis oscillation, ruaj khov heev, haum rau siab -ceev lub teeb- load tej yam kev mob, xws li siab - ceev turbine machinery.
4. Kev faib tawm los ntawm Cov Khoom Siv Bearing
Babbitt hlau bearings: Mos alloys raws li cov tin los yog txhuas, nrog rau zoo heev embedability thiab ua raws, thiab tsis yooj yim rau kev puas tsuaj rau phau ntawv. Haum rau hnyav -load, siab -ceev turbines thiab loj motors.
Copper-raws li alloy bearings: Xws li tin bronze thiab txhuas bronze, nrog siab load-cov kabmob muaj peev xwm thiab qaug zog. Haum rau kev sib xyaw nrog cov cav tov, dov mills, thiab lwm yam kev cuam tshuam rau kev thauj khoom.
Aluminium-raws li alloy bearings: Lub teeb yuag, zoo thermal conductivity, corrosion-resistant, haum rau turbocharged cav, thiab lwm yam.
Khoom -lubricant embedded bearings: Graphite los yog molybdenum disulfide embedded nyob rau hauv ib tug siab - zog tooj dag puag, muaj peev xwm ua tau ntev- lub sij hawm txij nkawm- tsis pub ua hauj lwm nyob rau hauv siab - kub, qis - ceev, thiab nyuaj -lubricate{{7} ib puag ncig
