Kev paub txog cov khoom hauv qab rau excavator

1 Txheej txheem cej luam:

Plaub lub log hauv "plaub lub log thiab ib txoj siv" yog hais txog: sprocket, idler, taug qab cov menyuam thiab cov menyuam nqa khoom.Belt hais txog kev khiav.Lawv muaj feem cuam tshuam ncaj qha rau kev ua haujlwm ntawm kev ua haujlwm thiab kev taug kev ntawm excavator, thiab nws qhov hnyav thiab kev tsim khoom tus nqi rau ib feem peb ntawm cov nqi tsim khoom ntawm excavator nws tus kheej.

2. — TRACK GROUP:

TRACK GROUP yog xa tawm lub ntiajteb txawj nqus ntawm lub excavator thiab lub nra ntawm kev ua haujlwm thiab taug kev mus rau hauv av.Excavators tuaj yeem muab faib ua steel TRACK GROUP thiab roj hmab TRACK GROUP raws li cov khoom siv.Cov hlau TRACK GROUP muaj kev hnav zoo, kev saib xyuas yooj yim thiab kev lag luam zoo, yog li nws tau siv dav.Roj Hmab TRACK GROUP feem ntau yog siv rau ntawm cov hydraulic excavators me me los tiv thaiv txoj kev puas tsuaj.

Cov khau khiav rau steel khiav kev faib tawm: muaj ob hom kev sib xyaw ua ke thiab sib xyaw ua ke.Kev sib koom ua ke TRACK GROUP taug qab nkawm khau muaj cov hniav mesh, uas zoo li mesh nrog cov sprocket, thiab cov khau khiav nws tus kheej dhau los ua cov kev sib tw ntawm cov log xws li cov menyuam.Nws cov yam ntxwv yog: yooj yim los tsim, tab sis hnav ceev.

Tam sim no, ntau lub hom phiaj ua ke ntawm excavators yog tus cwj pwm los ntawm lub suab me me, zoo revolving, thiab ceev ceev taug kev ntawm excavators.Lub neej ua haujlwm ntev, cov khoom siv ntawm cov khau khiav feem ntau yog dov phaj uas yog lub teeb hauv qhov hnyav, siab zog, yooj yim hauv kev tsim kho thiab pheej yig tus nqi.Rolled sheets muaj nyob rau hauv Shuzhong cov ntaub ntawv xws li ib leeg-bar, ob-bar thiab triple-bar.Tam sim no excavators siv peb tav.Nws cov yam ntxwv yog tias qhov siab ntawm cov tav yog me me, lub zog ntawm cov khau khiav yog loj, lub zog yog du, thiab lub suab nrov me me.

Muaj 4 qhov sib txuas ntawm lub phaj khiav, thiab muaj ob lub qhov ntxuav hauv nruab nrab, uas yog siv los txiav cov av nplaum.Muaj qhov sib tshooj ntawm ob lub khau uas nyob ib sab, thiab ob lub khau uas nyob ib sab tau ua rau hauv qhov sib tshooj.Tiv thaiv kom nruj dhau los ntawm kev sib tsoo ntawm cov lem.

Lub excavator ntawm cov av ntub dej tuaj yeem siv daim duab peb sab TRACK GROUP khau, thiab nws cov hlaws yog daim duab peb sab, uas tuaj yeem ua rau hauv av mos thiab txhim kho kev txhawb nqa.

3. — Sprocket:

Lub zog ntawm hydraulic excavator cav yog xa mus rau TRACK GROUP los ntawm kev mus ncig lub cev thiab lub log tsav.Nws yog qhov yuav tsum tau ua kom lub log tsav tsheb thiab cov saw hlau ntawm TRACK GROUP yog qhov zoo meshed, kev sib kis tau zoo, thiab TRACK GROUP tseem tuaj yeem ua tau zoo meshed thaum lub tes tsho tus pin hnav thiab ncab.Qhov tshwm sim ntawm "dhia hniav".Cov sprockets ntawm cov khiav khiav iav feem ntau yog muab tso rau tom qab.Nyob rau hauv txoj kev no, qhov ntev ntawm qhov tensioning seem ntawm txoj kev khiav yuav luv luv, lub zog poob tuaj yeem raug txo, thiab kev pabcuam lub neej ntawm txoj kev tuaj yeem txhim kho.

Raws li cov qauv, nws tuaj yeem muab faib ua: ib hom thiab cais hom

Raws li lub suab, nws tuaj yeem muab faib ua: sib npaug suab thiab suab tsis sib npaug

Khoom siv: 50Mn 45SIMN, thiab ua kom nws hardness ncav cuag HRC55-58

4.—Idler:

Lub idler yog siv los coj txoj kev khiav kom raug, uas tuaj yeem tiv thaiv nws los ntawm kev sib txawv thiab deviating ntawm txoj kev.Feem ntau ntawm cov hydraulic idlers kuj ua lub luag haujlwm ntawm rollers, uas tuaj yeem ua rau kom muaj kev sib cuag ntawm qhov chaw khiav mus rau hauv av thiab txo qhov tshwj xeeb siab., Lub log nto ntawm lub idler feem ntau yog ua los ntawm du nto, thiab muaj lub xub pwg nplhaib hauv nruab nrab rau kev taw qhia.Lub torus ntawm ob sab tuaj yeem txhawb nqa txoj kab tsheb ciav hlau thiab ua lub luag haujlwm ntawm cov menyuam.Qhov me me ntawm qhov kev ncua deb ntawm qhov ze tshaj plaws, qhov zoo dua qhov kev ua haujlwm idler

Khoom siv: feem ntau 40/50 steel los yog 35MN, cam khwb cia, quenched thiab tempered, hardness HB230-270

Qhov zoo: Txhawm rau kom tus idler ua haujlwm thiab ua kom nws lub neej ntev, lub radial khiav tawm ntawm lub log uas tig mus rau qhov chaw nruab nrab yuav tsum tsawg dua lossis sib npaug li 3MM, thiab nws yuav tsum raug muab tso rau hauv nruab nrab thaum nruab.

5. - Track roller:

Lub luag haujlwm ntawm cov chais yog xa tawm qhov hnyav ntawm lub excavator mus rau hauv av.Thaum lub excavator tsav tsheb ntawm txoj kev tsis sib xws, cov chais yuav raug cuam tshuam los ntawm av.Yog li ntawd, cov chais yog raug rau cov loads loj thiab kev ua haujlwm tsis zoo, feem ntau hauv plua plav.Qee lub sij hawm nws kuj tseem ntub dej hauv av nkos, yog li yuav tsum muaj lub foob zoo.

Khoom siv: Siv ntau tshaj 50mn los tsim.Lub log nto yog quenched, thiab hardness mus txog HRC48 ~ 57 kom tau txais kev hnav zoo.

Nta: Feem ntau ntawm lawv tau txais kev txhawb nqa los ntawm zawv zawg bearings.Thiab dustproof nrog floating roj foob.

Feem ntau tsuas yog yuav tsum tau ntxiv butter ib zaug thaum lub sijhawm kho dua tshiab, uas yooj yim rau kev saib xyuas ib txwm ua haujlwm ntawm excavator.

6.—— Cov menyuam nqa khoom

Lub luag haujlwm yog tuav lub TRACK GROUP, kom TRACK GROUP muaj qee qhov kev nro.

Raws li cov kev paub saum toj no, peb tuaj yeem nkag siab qhov kev paub zoo ntawm thaj tsam plaub-log, thiab muaj kev nkag siab dav dav ntawm thaj tsam plaub-log.

Raws li ib tug excavator, lub chassis taug kev ntaus ntawv ntawm lub bulldozer account rau ib quarter ntawm cov nqi tsim khoom ntawm tag nrho cov tshuab, uas qhia nws qhov tseem ceeb.

Rau ib co domestic thiab thoob ntiaj teb excavator hom thiab cov lis dej num yog raws li nram no:

Hauv tsev: Sany (SY) Liugong (CLG) Yuchai (YC) Xiamen Engineering (XG) Xugong (XE) Longgong (LG) Tuam Tshoj United (ZE) Sunward Intelligent (SWE)

Nyiv: Komatsu~(PC) Hitachi~(EX, UH, ZAX) Kobelco~(SK, K) Sumitomo~(SH) Kato~(HD) Kubota~(U, K, KH, KX) Ishikawa Island~ (IS , IHI) Takeuchi ~ (JB)

Kauslim: Doosan/Daewoo (DH, DX) Hyundai (R)

Tebchaws Asmeskas: Caterpillar (CAT) Case (CX)

Sweden: Volvo (VAVO, EC)

Lub teb chaws Yelemees: Atlas (ATLS)

thiab ntau ntxiv………

Hauv Komatsu excavators: PC hauv excavators stands rau TRACK GROUP hydraulic excavators, thiab D stands rau TRACK GROUP bulldozers.

Tus lej tom qab lub PC qhia qhov hnyav ua haujlwm ntawm lub excavator, uas tseem yog lub hauv paus rau kev paub qhov txawv ntawm qhov loj ntawm excavator.Piv txwv li, PC60, PC130, thiab PC200 sawv cev rau TRACK GROUP hydraulic excavators ntawm 6T, 13T, thiab 20T qib, feem.Txawm li cas los xij, yog tias PC200-2 tshwm sim, qhov kawg -2 ntawm no sawv cev rau algebra, yog li peb tuaj yeem nkag siab nws yog cov khoom thib ob ntawm Komatsu 200 TRACK GROUP hydraulic excavator nrog 20 tonnage.

Kev paub txog cov khoom lag luam kom nkag siab qee yam, tom qab ntawd cov txheej txheem tsim khoom ntawm cov txheej txheem tsim khoom yuav tsum muaj kev nkag siab dav dav:

Cov txheej txheem technical ntawm cov menyuam muaj cov kauj ruam hauv qab no:

Lub log lub cev: blanking → forging → tsheb ua → kev kho cua sov → roj drilling → hluav taws xob vuam → tiav tig → kom sib dhos → nias lub tes tsho tooj liab

Pem hauv ntej npog: blanking → roughing thiab tiav tig → drilling → countersinking → hloov hniav → oiling thiab cia

Txhawb nqa ncej: blanking → ntxhib tig → roj drilling → kho cua sov → zoo sib tsoo → cia

Tom qab tag nrho cov txheej txheem saum toj no ua tiav, cov txheej txheem sib dhos zaum kawg yog ua tiav.Cov haujlwm tshwj xeeb yog raws li hauv qab no:

Ntxuav thiab polishing → sib dhos → kev sim siab → refueling → sib tsoo → pleev xim → ntim thiab cia

Cov txheej txheem khiav ntawm idler suav nrog cov kauj ruam hauv qab no:

Lub log lub cev: blanking → casting → ntxhib thiab zoo tig → milling tshuab → drilling mounting qhov → chamfering → txuam → cia

Bracket: blanking → ntxhib tig → kho cua sov → milling tshuab (qee yam tsis xav tau milling) → nplua sib tsoo → sib txuam

Tom qab ua tiav ob kauj ruam saum toj no, mus rau qhov kawg kev sib dhos txheej txheem ua haujlwm.Cov haujlwm tshwj xeeb yog raws li hauv qab no: polishing → tu → lub log lub cev nias lub tes tsho tooj liab → sib dhos → kev sim siab → refueling → sib tsoo → pleev xim → ntim thiab cia

Cov txheej txheem thev naus laus zis ntawm lub log tsav yog raws li hauv qab no:

Forging → Thaum tshav kub kub kho → ntxhib thiab zoo tig → drilling (installation qhov) → chamfering → sib tsoo → kho → painting → ntim thiab cia

Cov txheej txheem chains yog raws li nram no:

Blanking → ob-sided milling → drilling → chamfering → puab square qhov milling
