Koj yuav kho lub iav tawg li cas?
Txoj kev kho cov iav feem ntau suav nrog: txoj kev sib hloov, txoj kev ntog, txoj kev kub forging, ntxig txoj kev thiab lwm yam.
(1) Kho txoj hauv kev rau kev puas tsuaj ntawm cov hniav iav
① Qhov kawg lub ntsej muag thim rov qab txoj kev kho cov hniav nto. Rau cov iav nrog ib nrab (xws li ib qho kawg) hnav ntawm tus hniav nto los yog hnav ntawm ib qho chaw ua haujlwm (ib txoj kev sib hloov), yog tias cov iav hnav yog qhov sib luag hauv lub dav hlau axial, nws yog kev lag luam siv lub ntsej muag kawg rov qab. (axial tig) txoj kev kho nws. nrog haum. Piv txwv li, qee qhov gearbox gearbox, vim kev hloov pauv ntau zaus thiab hloov, feem ntau muaj kev cuam tshuam rau ntawm ib qho kawg ntawm cov hniav iav. Piv txwv li, lub zog yog axially symmetrical, thiab lub taub hau tuaj yeem hloov kho kom txhim kho qhov cuam tshuam. Qee lub zog tau tsim los coj mus rau hauv tus account qhov tshwj xeeb uas yuav tsum tau yooj yim hloov thiab kho tom qab lawv cov khoom hauv zos (ntawm ib sab) thiab ib qho chaw ua haujlwm tau hnav.
② Cov txheej txheem surfacing kho cov hniav nto. Thaum cov iav hnav hnyav heev thiab muaj qhov hnyav hnyav los yog tawg, cov txheej txheem surfacing tuaj yeem xav txog kev kho. Feem ntau, txoj kev surfacing tuaj yeem tau txais txiaj ntsig kev lag luam ntau dua rau kev puas tsuaj ntawm cov iav loj thiab tseem ceeb, thiab nws tseem tuaj yeem rov pib tsim khoom sai li sai tau. Cov txheej txheem ntawm iav surfacing yog: annealing ua ntej vuam → tu → vuam → machining → tshav kub kho → tiav.
③ Cov hniav nto yog kho los ntawm kub forging. Thaum cov hniav ua hauj lwm ntawm cov iav iav yog hnav hnyav thiab cov hniav tuab yog txo qis, cov hlau ntawm cov hniav saum toj kawg nkaus tuaj yeem raug extruded mus rau cov hniav ua hauj lwm los ntawm kub forging kom tau cov hniav tuab nrog rau cov nyiaj machining rau cov hniav zoo. , thiab tom qab ntawd tsuas yog Weld overlay rau saum cov iav hniav. Piv nrog rau cov hniav nto surfacing txoj kev, txoj kev no yog ib qho yooj yim rau kev khiav lag luam, cov hlau fusion lub xeev yog zoo dua, thiab qhov zoo yog ib qho yooj yim los xyuas kom meej, tab sis nws yuav tsum tau kub forging txheej txheem thiab coj complex khoom txhawb nqa, thiab tus nqi kuj yog siab.
(2) Kho txoj kev rau cov hniav tawg
① Cov txheej txheem hniav ntxig yog siv los kho cov hniav tawg. Rau ib tus neeg cov hniav tawg, lwm cov hniav iav ntawm lub iav tsis zoo (tshwj xeeb yog cov hniav uas nyob ib sab ntawm cov hniav tawg yuav tsum tau them nyiaj rau); nyob rau tib lub sijhawm, yog tias qhov tseeb ntawm lub iav tsis siab heev thiab kev ua haujlwm ceev yog qhov tsawg, nws tuaj yeem kho tau los ntawm txoj kev ntxig ntxig.
② Splicing txoj kev los kho cov hniav tawg. Thaum lub nplhaib loj loj tawg, lossis thaum ib feem ntawm cov hniav ntawm cov iav loj dua puas lawm, nws tuaj yeem kho tau los ntawm splicing. Siv roj welding los yog saws (los yog toothless saw) txiav tawm qhov puas ntawm cov iav, thiab tom qab ntawd siv cov cuab yeej tshwj xeeb los kho cov iav deformed rau nws qhov qub, raws li pom hauv daim duab 9-30. Tom qab ntawd tshem tawm qhov yuav tsum tau ua los ntawm tib lub iav uas tsis tuaj yeem kho, lossis ua ib feem ntawm lub nplhaib iav nrog cov khoom qub lossis cov khoom zoo ib yam li cov iav qub raws li qhov loj thiab cov duab ntawm qhov thais, thiab txuas mus rau qhov thais.
Ua ntej welding, 45 degree zawj yuav tsum yog hauv av ntawm qhov chaw vuam raws li qhov dav ntawm 8-10 hli, thiab kev siv tshuab yuav tsum tau ua tom qab vuam. Txhawm rau kom ntseeg tau tias lub suab sib txawv ntawm qhov sib txuas thiab cov iav qub, qhov ntev ib txwm W yuav tsum tau ntsuas ntau zaus thaum tag nrho cov txheej txheem ntawm splicing.
③ Txoj kev surfacing kho cov hniav tawg. Thaum siv txoj kev surfacing los kho tus neeg cov hniav tawg, cov hniav tawg yuav tsum tau ua tib zoo txiav txim siab ua ntej vuam.
Cov kab nrib pleb, tshwj xeeb tshaj yog qaug zog, yuav tsum tau muab tshem tawm mus rau qhov tawg ua ntej vuam. Txhawm rau kom tsis txhob muaj kev cuam tshuam thermal ntawm cov txheej txheem vuam, cov iav tuaj yeem muab tso rau hauv dej, tsuas yog qhov chaw vuam tau raug rau saum npoo dej, thiab qhov chaw nyob ib sab ntawm qhov chaw vuam yog npog nrog ntaub asbestos.
(3) Kho cov iav tawg
① Kho cov iav qaug zog tawg. Rau qhov pib qaug zog micro-cracks ntawm iav hniav los yog rims thiab webs, drilling (passivation qhov) nyob rau hauv pem hauv ntej ntawm tawg propagation tuaj yeem tiv thaiv nws los ntawm kev nthuav dav kom ntev nws lub neej kev pab cuam. Nyob rau hauv qhov tseeb, rau qhov hnyav dua iav hniav qaug zog tawg, qhov kev nthuav tawm pem hauv ntej tsis meej, thiab nws yog qhov nyuaj rau nrhiav thiab txheeb xyuas txawm tias tsis muaj kev puas tsuaj. Nws tuaj yeem txiav txim siab pom tawm ntawm cov hniav seem raws li cov kev taw qhia tawg, thiab tom qab ntawd kho lawv raws li cov hniav tawg.
② Kho cov kab nrib pleb hauv iav tshuab. Rau qhov chaw (los yog subsurface) cov kab nrib pleb uas tseem loj hlob tsis tu ncua, lawv tuaj yeem raug tshem tawm los ntawm kev sib tsoo lossis ua ntaub ntawv kom ntev lawv lub neej kev pab cuam. Thaum tshem cov kab nrib pleb, txheej txheej deformation ntawm qhov tawg yuav tsum tau muab tshem tawm thiab.
③ Kho cov kab nrib pleb hauv cov khoom siv iav. Tom qab localization thiab quantification los ntawm kev ntsuam xyuas tsis muaj kev puas tsuaj, cov tshuab tawg yog siv los ntsuas lub neej seem, thiab tom qab ntawd muab pov tseg kom tsim nyog; txwv tsis pub siv, los yog muab pov tseg thiab hloov.
(4) Kho qhov deformation mus tas li ntawm cov iav
① Kho me ntsis yas deformation ntawm iav. Kev puas tsuaj tsawg tsawg, xws li burrs, me me indentations, ridges, thiab lwm yam, tuaj yeem txiav los ntawm kev ua ntaub ntawv thiab txiav cov yas deformed convex. Yog hais tias cov khoom siv ntawm cov hniav yog mos heev, qhov chaw ntxiv dag zog (los yog kev kho mob hauv zos), xws li kev txhaj tshuaj peening, tuaj yeem muab tau. Yog tias lub lubrication tsis zoo, lub lubrication tuaj yeem txhim kho. Piv txwv li, rau lub zog nrog kev puas tsuaj, lub siab-viscosity lubricating roj uas muaj huab cua additives tuaj yeem siv los txhim kho cov txheej txheem lubrication.
② Kho cov yas deformation loj ntawm cov iav. Rau kev puas tsuaj loj xws li qhov kawg ntawm lub ntsej muag cuam tshuam cov yas deformation, nyob rau hauv cov xwm txheej ntawm axially adjustable lub taub hau, qhov kawg lub ntsej muag rov qab txoj kev yog siv rau cov khoom puas. Los yog thaum nws muaj txiaj ntsig (xws li cov khoom loj) thiab kub forging muaj, nws tuaj yeem kho los ntawm kub forging. Rau cov iav uas muaj cov yas deformation loj heev, ntxiv rau kev siv cov kev ntsuas saum toj no los kho, qhov tshwj xeeb thauj khoom lossis (thiab) ib puag ncig thiab lwm yam uas ua rau kev puas tsuaj yuav tsum raug cais tawm.
③ Kho cov yas khoov loj deformation ntawm iav ncej. Thaum lub iav ncej muaj dabtsi yog khoov yas deformation, nws tuaj yeem kho tau los ntawm kev siv lub siab (nrog rau cov xovxwm) straightening thiab txias straightening. Yuav kom kov yeej cov kev cuam tshuam ntawm elastic tsis ua hauj lwm, rau iav ncej nrog ib txoj kab uas hla (qhov siab tshaj plaws txoj kab uas hla) tsawg tshaj li 50 hli, nws yuav tsum tau rhuab mus rau 400 ~ 500 degree thiab khaws cia rau 0.5 ~ 1h; rau iav shafts nrog txoj kab uas hla loj thiab (los yog) loj deformation, ces cov cua kub yuav tsum tau kom tsim nyog ({6}} degree), vim straightening nyob rau hauv xws li kub tej yam kev mob yuav xyuas kom meej stability ntawm straightening rov qab.
