Hauv kev ua haujlwm ntawm lub tshuab khawb av, lub thoob pin, ua ib feem tseem ceeb uas txuas lub boom, linkage thiab lub thoob, raug rau lub zog loj heev thiab torque. Qhov loj ntawm lub thoob pin, kev tsim qauv thiab kev ua haujlwm ntev yog txawv rau ntau qhov tonnages ntawm cov tshuab khawb av, thiab kev xaiv zoo yog qhov tseem ceeb los txuas lub neej ntawm cov khoom siv thiab txhim kho kev ua haujlwm ntawm kev tsim kho.
1. 5 ~ 8 tons mini excavator: qhov tseem ceeb ntawm kev ywj pheej, qhov yuav tsum tau ua kom raug siab
Cov qauv no feem ntau yog siv rau hauv kev tsim kho nrog qhov chaw tsawg, xws li txoj kev hauv nroog thiab kev ua vaj tse, nrog rau kev txav mus los ntau zaus, xav tau qhov tseeb ntawm kev sib hloov thiab kev hnav tsis kam ntawm lub thoob thoob. Pom zoo siv kev kho mob tempered + nitriding ntawm cov pa roj carbon nruab nrab hlau alloy steel thoob thoob, lub cheeb feem ntau yog ntawm 45 ~ 60mm, lub teeb yuag, teb sai.
2. 13 ~ 20 tons ntawm cov excavators nruab nrab: lub zog thiab kev cuam tshuam yog ob qho tseem ceeb
Cov khoom siv no feem ntau siv rau hauv kev tsim kho vaj tse, vaj tse thiab cov haujlwm hauv nroog, nrog rau kev ua haujlwm siab. Cov thoob khib nyiab yuav tsum muaj kev tiv thaiv tensile thiab shear siab dua, feem ntau siv cov ntaub ntawv 40Cr lossis 42CrMo, qhov chaw ntawm kev kho mob quenching siab. Txoj kab uas hla yog 65 ~ 80 hli, yuav tsum tau siv nrog cov bushing tuab.
3. Cov tsheb khawb av loj tshaj 30 tons: qhov kev xaiv ruaj khov rau cov khoom thauj hnyav heev
Cov tsheb khawb av loj feem ntau siv rau hauv cov mines, quarries thiab lwm yam kev ua haujlwm hnyav, lub thoob thoob yuav tsum tsis txhob tsuas yog tiv taus kev cuam tshuam, tab sis kuj rau kev sib ntswg thiab qaug zog. Nws feem ntau yog ua los ntawm cov hlau alloy muaj zog, uas yog forged tag nrho thiab quenched los ntawm qhov nruab nrab zaus quenching thiab tempering. Lub cheeb tsam feem ntau yog ntau tshaj 100 hli, thiab qhov hnyav tuaj yeem yog kaum tawm kilograms.
Cov Lus Qhia Xaiv:
- Thov xyuas kom tseeb tias qhov kam rau ntawm txoj kab uas hla ntawm lub thoob thiab lub qhov rooj zaum yog nyob rau hauv ± 0.02 hli.
- Ua tib zoo saib cov khoom siv thiab lubrication ntawm lub tes tsho kom tsis txhob muaj kev sib txhuam qhuav.
- Qhov chaw ua haujlwm kub heev, nws raug pom zoo kom siv cov khoom siv tiv taus cua sov uas tawv.
(Kev xaiv kom raug tsis yog tsuas yog txhim kho kev tsim kho kom zoo ntawm tag nrho lub tshuab xwb, tab sis kuj tseem ua rau lub neej ua haujlwm ntawm lwm cov khoom siv (xws li tes txav, thoob) thiab txo qhov kev tawg.)
Peb muaj ntau hom thoob thoob, txhawb nqa qhov ntau thiab tsawg thiab hom khoom haum, txais tos hu rau peb kom tau txais cov lus qhia xaiv thiab kev txhawb nqa kev tshaj lij.
