Ntxiv rau qhov preset clearance bearing Cheebtsam, Timken tau tsim tsib txoj hauv kev uas siv tau rau kev teeb tsa cov kabmob clearance (xws li SET-RIGHT, ACRO-SET, PROJECTA-SET, TORQUE-SET thiab CLAMP-SET) raws li phau ntawv hloov kev xaiv.Xa mus rau Table 1- "Kev sib piv ntawm tapered roller bearing set clearance method" los piav qhia txog ntau yam ntawm cov txheej txheem no nyob rau hauv lub rooj hom.Thawj kab ntawm cov lus no piv cov peev txheej ntawm txhua txoj hauv kev kom tswj tau qhov "ntau" ntawm cov kabmob kev tshem tawm.Cov txiaj ntsig no tsuas yog siv los piav qhia tag nrho cov yam ntxwv ntawm txhua txoj hauv kev teeb tsa kev tshem tawm, tsis hais seb qhov kev tshem tawm puas tau teeb tsa rau "preload" lossis "axial clearance".Piv txwv li, nyob rau hauv SET-RIGHT kem, qhov kev cia siab (siab tshaj qhov ncua sij hawm lossis 6σ) tshem tawm kev hloov pauv, vim yog cov kabmob tshwj xeeb thiab kev tswj hwm vaj tse / ncej, tuaj yeem nyob ntawm qhov tsawg kawg nkaus ntawm 0.008 ntiv mus rau 0.014 ntiv tes.Qhov kev tshem tawm tuaj yeem muab faib nruab nrab ntawm axial clearance thiab preload kom ua tiav qhov kev ua tau zoo ntawm cov kabmob / daim ntawv thov.Xa mus rau daim duab 5- "Thov Siv Txoj Kev Tsis Siv Neeg los Teeb Cov Kabmob Clearance".Daim duab no siv plaub lub log tsav tsheb ua liaj ua teb tsim qauv ua piv txwv los piav qhia txog kev siv dav dav ntawm tapered roller bearing setting clearance method.
Peb yuav tham txog cov ntsiab lus tshwj xeeb, kev xav thiab cov txheej txheem raug cai ntawm txhua txoj kev thov hauv cov tshooj hauv qab no ntawm cov qauv no.Txoj kev SET-RIGHT tau txais qhov yuav tsum tau tshem tawm los ntawm kev tswj lub siab ntev ntawm cov kabmob thiab cov txheej txheem kev teeb tsa, tsis tas yuav tsum tau kho tus kheej TIMKEN tapered roller bearing.Peb siv cov cai ntawm qhov yuav tshwm sim thiab kev txheeb cais los kwv yees cov txiaj ntsig ntawm cov kev zam no ntawm kev coj tus kheej.Feem ntau, txoj kev SET-RIGHT yuav tsum nruj dua kev tswj ntawm machining tolerances ntawm lub tog raj kheej / bearing vaj tse, thaum tswj nruj me ntsis (nrog rau kev pab ntawm cov qhab nia raug thiab cov lej) qhov tseem ceeb kam rau ua ntawm cov bearings.Txoj kev no ntseeg hais tias txhua yam khoom siv hauv lub rooj sib txoos muaj qhov tseem ceeb rau kev ua siab ntev thiab yuav tsum tau tswj xyuas nyob rau hauv ib qho chaw.Txoj cai lij choj ntawm qhov tshwm sim qhia tau hais tias qhov tshwm sim ntawm txhua qhov kev sib koom ua ke yog ib qho kev kam rau me me lossis kev sib xyaw ua ke ntawm qhov loj me me heev.Thiab ua raws li "kev faib tawm ntawm kev ua siab ntev" (Daim duab 6), raws li kev cai lij choj, lub superposition ntawm txhua qhov ntau thiab tsawg yuav poob rau hauv nruab nrab ntawm qhov ua tau ntev ntawm kev kam rau siab.Lub hom phiaj ntawm SET-RIGHT txoj kev yog los tswj tsuas yog qhov tseem ceeb tshaj plaws kam rau ua uas cuam tshuam cov kabmob clearance.Cov kev kam rau siab no tuaj yeem nyob hauv cov kabmob, lossis tuaj yeem koom nrog qee qhov kev sib txuas (piv txwv li, qhov dav A thiab B hauv daim duab 1 lossis daim duab 7, nrog rau cov ncej sab nraud thiab cov kabmob vaj tsev sab hauv txoj kab uas hla).Qhov tshwm sim yog tias, nrog qhov tshwm sim siab, qhov kev tshem tawm cov kabmob yuav poob rau hauv txoj kev siv tau SET-RIGHT.Daim duab 6.
