Qhib Tuag Forgings Chaw tsim tshuaj paus nyob rau hauv Suav teb

FORGED SHAFT / STEP SHAFT / SPINDLE / AXLE NTXIV



Daim ntawv thov teb ntawm forgings ncej yog
Ncej forgings (mechanical Cheebtsam) Ncej forgings yog cov khoom cylindrical uas hnav nyob rau hauv nruab nrab ntawm cov kabmob lossis hauv nruab nrab ntawm lub log lossis hauv nruab nrab ntawm lub iav, tab sis ob peb yog square. Lub taub hau yog ib qho khoom siv uas txhawb nqa ib feem thiab tig nrog rau kev xa cov lus tsa suab, torque lossis khoov lub sijhawm. Feem ntau, nws yog cov hlau pas nrig, thiab txhua ntu tuaj yeem muaj qhov sib txawv. Qhov chaw ntawm lub tshuab uas ua rau lub slewing txav yog mounted rau ntawm ncej. Suav lub npe ncej forging hom ncej, mandrel, tsav ncej khoom siv 1, carbon steel 35, 45, 50 thiab lwm yam high-zoo carbon structural steel vim hais tias ntawm nws cov high-qib neeg kho tshuab zog, ntau daim ntaub ntawv, uas 45 steel yog siv feem ntau dav. Txhawm rau txhim kho nws cov khoom siv kho tshuab, normalizing lossis quenching thiab tempering yuav tsum tau ua. Rau cov qauv shafts uas tsis tseem ceeb los yog muaj zog tsawg, carbon structural steels xws li Q235 thiab Q275 tuaj yeem siv. 2, alloy steel Alloy steel muaj ntau dua txhua yam khoom, tab sis tus nqi yog kim dua, feem ntau yog siv rau shafts nrog tshwj xeeb yuav tsum tau. Piv txwv li, shafts high-speed shafts siv zawv zawg bearings, feem ntau siv qis-carbon alloy structural steels xws li 20Cr thiab 20CrMnTi, tuaj yeem txhim kho qhov hnav tsis kam ntawm cov ntawv xov xwm tom qab carburizing thiab quenching; lub rotor ncej ntawm lub turbo generator ua haujlwm nyob rau hauv qhov kub thiab txias, kev kub ceev thiab hnyav load. Nrog rau cov khoom kub kub zoo, cov khoom siv hlau alloy xws li 40CrNi thiab 38CrMoAlA feem ntau siv. Qhov khoob ntawm cov ncej yog nyiam rau forgings, ua raws li cov hlau puag ncig; rau cov qauv loj los yog complex, cam khwb cia hlau los yog hlau ductile tuaj yeem txiav txim siab. Piv txwv li, kev tsim cov crankshaft thiab camshaft los ntawm cov khoom siv hlau muaj qhov zoo ntawm tus nqi qis, kev co zoo nqus, tsis tshua muaj siab rau kev ntxhov siab, thiab lub zog zoo. Cov qauv siv tshuab ntawm cov ncej yog cov nqaj, uas feem ntau yog tig, yog li nws qhov kev ntxhov siab feem ntau yog lub voj voog sib luag. Cov hom kev ua tsis tiav muaj xws li qaug zog tawg, overload tawg, thiab ntau elastic deformation. Qee qhov chaw nrog cov hubs feem ntau yog ntsia rau ntawm cov ncej, yog li feem ntau cov ncej yuav tsum tau ua rau hauv cov kauj ruam nrog cov khoom loj. Structural Classification Structural Design Cov qauv tsim ntawm cov ncej yog ib kauj ruam tseem ceeb hauv kev txiav txim siab cov qauv tsim nyog thiab tag nrho cov qauv ntawm cov ncej. Nws muaj cov hom, qhov loj thiab txoj hauj lwm ntawm qhov chaw mounted ntawm lub ncej, txoj kev ntawm ib feem yog tsau, xwm, kev taw qhia, qhov loj thiab kev faib ntawm lub load, hom thiab qhov loj ntawm cov kabmob, qhov khoob ntawm cov ncej, kev tsim khoom thiab kev sib dhos, kev teeb tsa thiab kev thauj mus los, cov ncej Lub deformation thiab lwm yam cuam tshuam. Tus tsim qauv tuaj yeem tsim raws li cov kev xav tau tshwj xeeb ntawm cov ncej. Yog tias tsim nyog, ntau lub tswv yim tuaj yeem muab piv rau xaiv qhov zoo tshaj plaws tsim.

Cov hauv qab no yog cov qauv ncej dav dav tsim qauv

1. Txuag cov ntaub ntawv, txo qhov hnyav, thiab siv lub zog sib npaug. Dimensional los yog loj seem coefficient cross-sectional duab.

2, yooj yim kom raug txoj hauj lwm, stabilize, sib sau ua ke, disassemble thiab kho qhov chaw ntawm lub ncej.

3. Siv ntau yam kev ntsuas los txo kev ntxhov siab thiab txhim kho lub zog.

4. Yooj yim los tsim thiab xyuas kom raug.

Kev faib tawm ntawm cov shafts Cov shafts Muaj peev xwm muab faib ua crankshafts, ncaj shafts, saj zawg zog shafts, khoom shafts, hollow shafts, rigid shafts, thiab saj zawg zog shafts ( saj zawg zog shafts ) nyob ntawm seb cov yam ntxwv ntawm cov ncej.

Cov ncej ncaj tuaj yeem muab faib ntxiv rau

1 ncej, uas yog raug rau ob qho tib si dabtsi yog khoov lub sij hawm thiab torque, thiab yog lub feem ntau ncej nyob rau hauv machinery, xws li shafts nyob rau hauv ntau yam ceev reducers.

2 mandrel, siv los txhawb qhov kev sib hloov tsuas yog ua rau lub sijhawm khoov yam tsis muaj kev sib kis torque, qee qhov kev sib hloov mandrel, xws li lub qag ntawm lub tsheb ciav hlau, thiab lwm yam., qee qhov mandrel tsis tig, xws li cov ncej txhawb nqa lub rub. .

3 Transmission ncej, feem ntau yog siv los xa cov torque yam tsis muaj dabtsi yog khoov lub sijhawm, xws li ntev optical axis hauv crane txav mechanism, tsav ncej ntawm lub tsheb, thiab lwm yam.

Cov khoom siv ntawm cov ncej yog cov pa roj carbon steel lossis hlau alloy, thiab cov hlau ductile lossis alloy cam khwb cia hlau kuj tseem siv tau. Lub peev xwm ua haujlwm ntawm cov ncej feem ntau yog nyob ntawm lub zog thiab nruj, thiab kev kub ceev nyob ntawm qhov kev vibration stability. Daim ntawv thov Torsional stiffness Lub torsional txhav ntawm lub ncej yog xam raws li tus nqi ntawm torsional deformation ntawm lub ncej thaum lub sij hawm ua hauj lwm, ntsuas nyob rau hauv cov nqe lus ntawm lub torsion lub kaum sab xis ib meter ntawm ncej ntev. Lub torsional deformation ntawm tus ncej yuav tsum cuam tshuam rau kev ua haujlwm thiab kev ua haujlwm raug ntawm lub tshuab. Piv txwv li, yog hais tias lub torsion lub kaum sab xis ntawm lub camshaft ntawm lub internal combustion engine yog loj heev, nws yuav cuam tshuam rau qhov tseeb qhib thiab kaw lub sij hawm ntawm lub valve; lub torsion lub kaum sab xis ntawm qhov kis tau tus mob ntawm lub gantry crane motion mechanism yuav cuam tshuam rau synchronism ntawm lub log tsav; Ib tug loj torsional txhav yog yuav tsum tau rau shafts uas muaj kev pheej hmoo ntawm torsional vibration thiab shafts nyob rau hauv lub operating system.

Cov kev cai 1. Machining raug

1) Dimensional accuracy Qhov tseeb qhov tseeb ntawm cov ncej feem ntau yog hais txog txoj kab uas hla thiab qhov tseeb ntawm cov ncej thiab qhov tseeb qhov tseeb ntawm qhov ntev ntawm ncej. Raws li cov kev xav tau ntawm kev siv, qhov tseeb ntawm cov ntawv xov xwm tseem ceeb feem ntau yog IT6-IT9, thiab cov ntawv xov xwm precision kuj yog mus txog IT5. Qhov ntev ntawm ncej yog feem ntau teev raws li qhov nominal loj. Rau txhua kauj ruam ntev ntawm cov kauj ruam ncej, lub siab ntev tuaj yeem muab raws li qhov yuav tsum tau siv.

2) Geometric precision Ncej qhov chaw feem ntau txhawb nqa ntawm cov kabmob los ntawm ob phau ntawv sau. Ob phau ntawv no yog hu ua phau ntawv txhawb nqa thiab tseem yog cov ntaub ntawv sib dhos rau cov ncej. Ntxiv nrog rau qhov tseeb qhov tseeb, qhov tseeb geometric (roundness, cylindricity) ntawm phau ntawv txhawb nqa yog feem ntau xav tau. Rau cov ntawv xov xwm ntawm qhov tseeb dav dav, qhov yuam kev geometry yuav tsum raug txwv rau txoj kab uas hla. Thaum qhov yuav tsum tau muaj siab, qhov kev kam rau siab tso cai yuav tsum tau teev rau ntawm daim duab kos.

3) Kev sib koom ua ke ntawm qhov tseeb Lub coaxiality ntawm mating journals (cov phau ntawv journal ntawm cov neeg tsav tsheb sib sau ua ke) nyob rau hauv cov ncej qhov txheeb ze rau cov ntawv xov xwm txhawb nqa yog ib qho yuav tsum muaj rau lawv qhov kev sib koom ua ke. Feem ntau, cov ncej nrog ib txwm precision, qhov sib txuam precision nrog kev hwm rau lub radial runout ntawm cov ntawv xov xwm txhawb nqa feem ntau yog 0.01-0.03 hli, thiab qhov siab-precision ncej yog 0.001-0.005 hli. Tsis tas li ntawd, qhov sib koom ua ke qhov tseeb kuj yog coaxiality ntawm sab hauv thiab sab nrauv cylindrical, qhov perpendicularity ntawm axially positioned kawg lub ntsej muag thiab cov kab axial, thiab lwm yam. 2, deg roughness Raws li qhov tseeb ntawm lub tshuab, kev ua haujlwm ceev, qhov kev xav tau ntawm qhov chaw ntawm cov ncej kuj txawv. Feem ntau, qhov nto roughness Ra ntawm phau ntawv txhawb nqa yog 0.63-0.16 μm; Qhov saum npoo roughness Ra ntawm cov ntawv sib txuam yog 2.5-0.63 μ m.

Kev siv thev naus laus zis 1, kev xaiv cov khoom siv ntawm cov khoom siv ntawm cov ncej, Feem ntau yog nyob ntawm lub zog, nruj, hnav tsis kam thiab kev tsim cov txheej txheem ntawm cov ncej, thiab siv zog rau kev lag luam.
