Yuav Ua Li Cas Xaiv Fit Tolerances rau Bearing Installation? Lub nplhaib puab nrog ncej, thiab lub nplhaib sab nraud nrog cov kabmob vaj tse puas siv cuam tshuam haum lossis tshem tawm haum?

Cov ntsiab cai tseem ceeb rau kev xaiv haum
Kev xaiv haum haum nyob ntawm qhov kev taw qhia ntawm kev thauj khoom, kev hloov lub xeev ntawm cov kabmob rings, thiab cov kev pabcuam (xws li, qhov kub thiab txias, qhov xav tau).
Txoj cai tseem ceeb: Lub nplhaib uas tig nrog lub nra yuav tsum siv qhov cuam tshuam kom haum; lub nplhaib nyob ruaj ruaj tuaj yeem siv qhov kev tshem tawm haum lossis kev hloov pauv haum.
Haum rau puab nplhaib & ncej
Kev xaiv ua ntej: cuam tshuam haum (xws li, H7 / k6, H7 / m6 rau nruab nrab loads; H7 / n6 rau hnyav loads lossis siab precision).
Yog vim li cas: Lub nplhaib puab feem ntau tig nrog cov ncej thiab bears radial loads. Ib qho kev cuam tshuam haum tiv thaiv tus txheeb ze slipping (skidding) nruab nrab ntawm lub nplhaib puab thiab ncej, tsis txhob hnav los yog kev puas tsuaj rau lub ncej ncej.
Kev zam: Rau lub teeb loads, tsis tshua muaj ceev, los yog cov xwm txheej uas yuav tsum tau yooj yim disassembly, kev hloov haum (xws li, H7 / h6) yuav siv tau.
Haum rau Lub Nplhaib Sab Nraud & Bearing Vaj Tsev
Qhov tseem ceeb xaiv: Clearance haum (xws li, H7 / j6, H7 / h7) los yog xoob hloov haum.
Yog vim li cas: Lub nplhaib sab nraud feem ntau nyob ruaj ruaj rau cov kabmob vaj tsev. Lub clearance haum tso cai rau cov kabmob nthuav dav nrog qhov kub thiab txias thaum lub sijhawm ua haujlwm, tsis txhob muaj kev ntxhov siab sab hauv uas tuaj yeem cuam tshuam rau kev sib hloov precision lossis puas rau cov kabmob.
Kev zam: Yog tias lub nplhaib sab nraud xav tau tig (xws li, qee qhov tshwj xeeb kis tau tus mob), kev cuam tshuam haum yuav tsum tau siv rau lub nplhaib sab nraud, thaum lub nplhaib puab txais kev pom zoo / kev hloov pauv.
Cov Lus Qhia Ntxiv
Rau siab - cov khoom siv precision (piv txwv li, cov cuab yeej siv tshuab), cov qib siab kam rau ua (piv txwv li, IT5-IT6) raug pom zoo los xyuas kom meej qhov kev sib hloov.
Rau cov ntawv thov uas muaj qhov sib txawv ntawm qhov kub thiab txias, qhov haum yuav tsum tau hloov kho kom tsim nyog- nce clearance rau siab - qhov kub thiab txias ib puag ncig los them rau thermal expansion.
