Feem ntau niaj hnub piston sab hauv combustion engine yog nruab nrog lub cev pib nrog lub tshuab hluav taws xob.Kev sib kis ntawm torque los ntawm lub oob khab mus rau lub crankshaft yog nqa tawm los ntawm lub nplhaib iav mounted ntawm lub flywheel - nyeem tag nrho cov no, nws lub hom phiaj, tsim, xaiv thiab kho nyob rau hauv tsab xov xwm.
Dab tsi yog flywheel crown?
Lub flywheel nplhaib iav (flywheel iav rim) yog ib feem ntawm lub piston sab hauv combustion engine, ib tug loj-inch iav uas muab torque kis tau tus mob ntawm lub oob khab mus rau lub cav crank mechanism.
Lub kaus mom yog ob qho tib si ntawm KShM thiab lub cav pib qhov system, nws yog nruj nreem mounted ntawm lub flywheel thiab koom nrog cov pib iav.Thaum pib, lub torque los ntawm lub oob khab kis tau los ntawm lub iav, nplhaib thiab flywheel mus rau lub crankshaft thiab cov seem ntawm lub cav tshuab, thiab tom qab tig tawm lub pib system, lub nplhaib ua raws li ib tug ntxiv loj ntawm lub flywheel.
Txawm hais tias tus qauv tsim yooj yim, flywheel crown plays lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm lub cav, yog li, yog tias tsim nyog, hloov thiab kho, koj yuav tsum ua lub luag haujlwm rau kev xaiv ntawm ntu no.Thiab txhawm rau ua qhov kev xaiv zoo, koj yuav tsum nkag siab txog tus qauv tsim, cov yam ntxwv thiab cov yam ntxwv ntawm cov yas.
Hom, tsim thiab yam ntxwv ntawm flywheel crown
Ua ntej ntawm tag nrho cov, nws yuav tsum tau muab sau tseg tias niaj hnub no ob hom flywheels yog siv - nrog ib tug tshem tau thiab tsis tshem tau crown.Feem ntau yog cov flywheels nrog lub nplhaib tshem tawm - cov khoom no yooj yim dua thiab txhim khu kev qha hauv kev ua haujlwm, lawv muaj kev ruaj ntseg siab thiab tso cai rau koj txuag ntawm kev tsim thiab kho tsheb.Peb yuav tsis xav txog flywheels nrog cov yas tsis tshem tau ntawm no.
Structurely, tag nrho cov crowns yog heev yooj yim: nws yog ib tug steel rim, nyob rau sab nrauv uas cov hniav yog tig mus koom nrog lub starter iav.Lub crown yog ua los ntawm ntau qib ntawm cov hlau, nws yog rigidly mounted ntawm flywheel thiab yuav tsum tau hloov yog tias tsim nyog.
Roj siab sensors ua ob lub luag haujlwm tseem ceeb:
• Ceeb toom tus neeg tsav tsheb txog cov roj tsawg hauv lub cev;
• Tswb txog qis / tsis muaj roj hauv lub cev;
• Tswj cov roj siab hauv lub cav.
Cov sensors txuas nrog cov roj tseem ceeb ntawm lub cav, uas tso cai rau koj los saib xyuas cov roj siab thiab nws qhov muaj nyob rau hauv cov roj system (qhov no kuj tso cai rau koj los xyuas cov roj twj tso kua mis, yog tias nws ua haujlwm tsis zoo, cov roj tsuas ua tau. tsis nkag rau kab).Niaj hnub no, sensors ntawm ntau hom thiab lub hom phiaj yog ntsia rau ntawm lub cav, uas yuav tsum tau piav qhia ntau yam ntxiv.
Pressurized flywheel nplhaib
Bolt-on flywheel nplhaib
Nyob rau hauv rooj plaub thib ob, flange nrog ib tug xov tooj ntawm bolt qhov yog muab nyob rau hauv lub puab nto ntawm lub crown, uas yog ib feem ntawm lub flywheel.Feem ntau, cov yas zoo li no tau siv rau ntawm lub cav muaj zog, thaum pib uas cov iav txhuam hniav raug rau cov khoom tseem ceeb.Qhov kev sib txuas bolted tso cai rau koj los hloov lub kaus mom hnav yooj yim yam tsis siv cov cuab yeej tshwj xeeb lossis cov khoom siv.
Flywheel crowns muaj peb yam tseem ceeb:
• Txoj kab uas hla;
• Cov hniav Z;
• Meshing module (cov hniav module, log module) m.
Txoj kab uas hla thiab tus naj npawb ntawm cov hniav ntawm cov yas nyob rau hauv ntau qhov kev txwv, cov yam ntxwv no yuav txawv txawm tias cov cav ntawm tib cov qauv, tab sis nrog ntau hom kev pib.Feem ntau, tus naj npawb ntawm cov hniav nyob hauv thaj tsam ntawm 113 - 145 daim, thiab txoj kab uas hla ntawm cov yas yog los ntawm 250 hli ntawm cov neeg caij tsheb cav txog 500 hli lossis ntau dua ntawm cov tshuab hluav taws xob muaj zog.
Lub meshing modulus yog qhov piv ntawm txoj kab uas hla ntawm lub voj voog sib faib rau tus naj npawb ntawm cov hniav ntawm cov yas.Lub voj voog sib faib yog lub voj voog raws li kev faib cov hniav ntawm cov iav ua ob ntu (sab ceg thiab lub taub hau), nws nyob ze li ntawm nruab nrab ntawm qhov siab ntawm cov hniav.Tus nqi ntawm lub meshing modulus ntawm flywheel nplhaib iav yog li ntawm 2 mus rau 4.25 increments ntawm 0.25.Lub meshing module yog cov yam ntxwv tseem ceeb tshaj plaws hauv kev xaiv ntawm lub kaus mom thiab lub iav oob khab - cov khoom no yuav tsum muaj tus nqi zoo ib yam, txwv tsis pub lawv cov hniav yuav tsis sib xws, uas yuav ua rau hnyav hnyav ntawm qhov chaw, lossis lub tsheb ciav hlau yuav tsis sib haum. ua haujlwm txhua.
Raws li txoj cai, cov yam ntxwv tseem ceeb ntawm cov nplhaib (meshing module thiab tus naj npawb ntawm cov hniav) tau qhia los ntawm cov chaw tsim khoom, cov lej no tuaj yeem siv ncaj qha rau lub kaus mom.Tag nrho cov yam ntxwv yuav tsum raug coj mus rau hauv tus account thaum xaiv cov yas.
Teeb meem ntawm kev xaiv thiab hloov lub nplhaib flywheel
Thaum lub sijhawm ua haujlwm ntawm lub cav, cov hniav ntawm lub kaus mom tau raug mob hnyav, uas tuaj yeem ua rau hnyav dua los ntawm kev ua haujlwm tsis raug ntawm lub oob khab (piv txwv li, yog tias Bendix tsis tshem lub iav tam sim ntawd ntawm lub kaus mom thaum pib lub cav lossis ua haujlwm tsis raug. lub iav txheeb ze rau lub crown).Yog li ntawd, thaum lub sij hawm, cov hniav ntawm lub crown grind thiab nti, uas ua rau ib tug deterioration nyob rau hauv pib lub cav los yog txawm mus rau qhov tsis muaj peev xwm ua tau nrog lub oob khab.Yog hais tias cov hniav hnav tawm, lub crown yuav tsum muab tig los yog hloov nrog ib tug tshiab.
Dismantling ntawm nias lub nplhaib iav
Cov hniav ntawm cov yas hnav tsuas yog los ntawm lub kaum sab xis sab saud, thiab sab ntawm cov hniav uas tig mus rau lub flywheel tseem nyob tsis tu ncua.Yog li ntawd, thaum hnav tseem ceeb heev, cov yas tuaj yeem raug tshem tawm, tig, thiab ntsia nrog tag nrho cov hniav sab nraud.Thaum hloov, nws yog ib qho tsim nyog yuav tau soj ntsuam qhov tseeb installation ntawm lub rim thiaj li tsis mus tsoo qhov seem ntawm flywheel.Lub cim tshwj xeeb ntawm lub kaus mom thiab flywheel pab ua qhov no.Nrog rov hnav dua, lub crown tsuas hloov mus rau ib qho tshiab.
Yuav hloov, koj yuav tsum xaiv ib tug toothed flywheel rim nrog zoo tib yam yam ntxwv uas qhov qub muaj.Kev saib xyuas tshwj xeeb yuav tsum tau them rau meshing module m - tus yam ntxwv no yuav tsum muaj lub ntsiab lus zoo ib yam li cov yas qub.Yog hais tias, nrog rau lub flywheel crown, lub oob khab pib kuj hloov, ces ob qho tib si yuav tsum muaj tib qhov kev koom tes module.Ntawd yog, thaum kho, nws yog qhov ua tau kom siv lub iav thiab lub nplhaib nrog ntau tus hniav sib txawv, tab sis tib lub sijhawm lawv cov m yuav tsum muaj tus nqi tib yam.
Lub crown yog hloov ntawm lub dismantled flywheel raws li cov lus qhia kho rau lub tsheb tshwj xeeb no.Raws li txoj cai, pressed crowns yuav raug tshem tawm thiab ntsia tsuas yog tom qab cua sov - ib feem nthuav thaum rhuab thiab yuav raug tshem tawm los yog ntsia nws lub rooj.Tom qab hloov pauv, nws yuav tsim nyog kom sib npaug ntawm flywheel, qhov kev ua haujlwm no yuav tsum tau ua rau ntawm qhov chaw tshwj xeeb.Nyob rau hauv lub neej yav tom ntej, lub crown tsis xav tau kev kho tshwj xeeb.
Nrog rau txoj kev xaiv thiab hloov cov flywheel nplhaib iav, lub cav yuav pib ntseeg siab, thiab lub iav tsheb ciav hlau yuav raug hnav tsawg heev.
