Li cas los xaiv cov kev qhia loj me me
Jun 12, 2025|
Xaiv cov kabmob sab xis (cov kabmob tseem ceeb thiab txuas cov pas nrig ntaus bearings) yog qhov tseem ceeb rau kev ua haujlwm cav thiab ntev. Ntawm no yog ib kauj ruam - {{2} -} Cov lus qhia loj rau koj tau txais qhov tseeb bearings rau koj lub cav.
1. NtsuasTus kws cog qoob looPhau ntawv ceevfaj deg
A. Siv micrometer
NtsuasPhau Ntawv Teev TsegthiabTso rau hauv Jouddiameters ntawm ntau lub ntsiab lus.
Kos rau:
Tawm - ntawm - round(sib txawv hauv lub taub ntawm tib txoj haujlwm)
Tus ntsia khuam(qhov sib txawv ntawm cov ntawv sau cia)
Qauv Qauv Qauv:
Phau Ntawv Tseem Ceeb:2.559" – 2.560"(65.00 - 65.02 hli)
Rod Journal:2.098" – 2.099"(53.28 - 53.30mm)
B. Tshawb xyuasTus kws cog qoob looYam tseem ceeb
Txheem (STD)- Tsis yog machining, thawj qhov loj.
Undersize (piv txwv li, 0.010 ", 0.020", 0.030 ", 0.040", 0.050 ")- Yog tias crank tau ua av.
A. tus qauv vs. undersize bearings
kev ua thiab kuaj cov khoom siv.
| Crankshaft Mob | Kaus Yuav Tsum Tau Ua |
|---|---|
| Unmodified (STD) | Txheem (STD) bearings |
| Machined (piv txwv li, 0.010 "hauv qab) | 0.010 "undersize bearings |
| Hnav loj heev (xav tau kev cai ua haujlwm) | Oversized bearings (tsis tshua muaj) |
B. Saib cov kabmob tsis meej
Clectance clearance:
Bearings Main: 0.0015" – 0.0025"(0.038 - 0.064mm)
Rod Bearings: 0.0010" – 0.0020"(0.025 - 0.051 hli)
Yuav ua li cas rau txheeb xyuas:
Kev sivPlastigau(yas ntsuas) ntsuas ntsuas ntsuas kom meej.
Ntsuas nrog aDial Bore Gale(ntau meej)
3. Xaiv cov kabmob khoom
Tooj dawb(OEM, nyob ntsiag to, ua cua sov zoo)
Tri - hlau (tooj liab - coj)(Kev ua yeeb yam, kho cov khoom siv siab siab)
Bimetal (hlau -} backed)(Kev khwv nyiaj txiag rov qab kho dua tshiab)
4. Kev txheeb xyuas zaum kawg ua ntej kev teeb tsa
✅ Khij cov cim(STD, 0.010, 0.020, thiab lwm yam)
✅ Xeem - haum bearings(Siv plastigau kom tshem tawm)
✅ Ntub ua ntej sib dhos(Siv lub cav sib dhos lube)
Kev ua txhaum ib txwm muaj kev zam
❌ Piv txwv tias txhua bearings yog tib yam(Honda b vs sib txawv!)
❌ Nws hom / hom(xws li, clevite mains nrog King Rods
❌ Tsis quav ntsej cov roj clearance(dhau nruj=Cav seizure, dhau xoob {{1} {1}= knecking)
