Feem ntau koj tuaj yeem hnov txog txoj hauv kev los ntawm kev siv lub tshuab bevel, uas suav nrog cov iav ncaj ncaj, kauv bevel iav, iav iav lossis cov iav hypoid.
Qhov ntawd yog Milling, Lapping thiab Sib Tsoo.Milling yog txoj hauv kev yooj yim los ua cov iav bevel.Tom qab ntawd tom qab milling, qee cov neeg siv khoom xaiv lapping, qee cov neeg siv khoom xaiv sib tsoo.Qhov txawv yog dab tsi?
Lapping belongs rau kev ua tiav, lub hom phiaj tseem ceeb tshaj plaws ntawm kev tshawb fawb cov hniav yog kom txo cov suab nrov thiab txhim kho qhov chaw sib cuag ntawm cov hniav iav.Lapping yog ib txoj kev ua tiav rau kev kho cov hniav zoo thiab txhim kho qhov zoo.Vim yog qhov yuam kev los ntawm kev txiav / milling lossis kev kho cua sov deformation ntawm cov kauj ruam dhau los, qhov tseeb meshing yog qis dua, lub hom phiaj ntawm cov hniav yog kom dim ntawm qhov chaw ntawm lub log los txhim kho cov yam ntxwv ntawm cov hniav lwj, xyuas kom lub log hniav ntsiag to, txhim kho tus neeg muaj peev xwm.
Lapping yog ib qho me me ntawm cov txheej txheem hlau txiav, uas yog ua tiav los ntawm kev ceev thiab quab yuam cuam tshuam nrog qhov sib txawv ntawm cov hniav.Yam tsawg kawg tus kws kho hniav yuav tsum kom txo suab nrov, qib ntawm cov suab nrov txo qhov sib txawv nyob ntawm cov txheej txheem cov txheej txheem cov hniav thiab cov iav sub-initial tej yam kev mob.Kev txhim kho ntawm cov hniav mus rau lub suab nrov tuaj yeem ntsuas los ntawm ntau yam precision mem tes theem.Cov hniav kev tshawb fawb kuj yuav tsum tsis muaj peev xwm thauj khoom ntawm lub iav khub, los ntawm lwm lub kaum sab xis, uas yog, thawj zaug kev sib cuag cheeb tsam ntawm cov hniav tsis rhuav tshem lub log, nws yog qhov zoo tshaj plaws los txhim kho qhov kev sib cuag ntawm qhov chaw.
Txawm hais tias lapping tsis tuaj yeem hloov kho kom raug rau cov iav khub zoo li txoj kev sib tsoo, txhim kho qhov tseeb ntawm cov iav, tab sis los ntawm qhov chaw tsim nyog qhov chaw nyob tswj tshuab, torque real-time tswj thev naus laus zis, thiab lwm yam, los yog tuaj yeem txhim kho kev sib cuag. cheeb tsam.Piv txwv li, raws li cov txheej txheem yuav tsum tau, cov hniav nto nruas zoo nyob rau hauv cov hniav los yog cov hniav ntev yog nce, thiab cov hniav nto tiv tauj cheeb tsam yog me me nyob rau hauv kev sib cuag ntev, txoj hauj lwm thiab deflection xeev.
Yog vim li cas rau Lapping
1. Tus nqi ntawm kev kho hniav yog tsawg, cov cuab yeej siv tus nqi qis, thiab nws yog qhov pom tseeb los txo cov suab nrov;
2. Lub khob hliav qab iav rau cov hniav yuav tsum tau siv, tab sis cov hniav nto ntawm lub log loj thiab lub log me me yog qhov zoo tshaj plaws.
3. Tom qab cov hniav yog cov iav iav kho cua sov, ob lub iav yog hauv av rau ib leeg, xws li iav tsis ua kom lub plhaub tawv tawv, thiab cov hniav sib xws, ua kom lub neej ntawm cov iav;
4. Rau tag nrho cov kis tau tus mob ntawm lub tsheb, lub ntsiab ceev ntawm lub tsheb (kawg kis tau tus mob) tsis yog ib qho tseem ceeb tom qab siv cov hniav sib tsoo, vim hais tias cov kis tau tus mob ntawm lub kis tau tus mob system, xws li kis tau tus mob, thiab tag nrho cov kis tau tus mob.Qhov tseeb ntawm chav tsev tsis yog siab dhau;
5. Txawm tias muaj cov khoom siv txawv teb chaws, kev kho cua sov yog siv los siv kev tshawb fawb rau lapping, thiab cov nqi tsim khoom tsis siab tshaj qhov sib tsoo.
Sib tsoo:Kev kho cua sov deformation yog tshem tawm tom qab cov hniav tawv tawv, thiab ntxiv dag zog rau cov iav precision thiab txhim kho qhov roughness ntawm cov hniav nto, thiab tseem yog feem ntau raws li cov txheej txheem sib tsoo.
Yuav Tsum Tau Siv Cov Hniav Ua Ntej Sib Tsoo
1. Qhov sib npaug ntawm lub railing yuav tsum zoo ib yam
Vim lub deformation tom qab iav carbon quenching, qhov tseeb yuav tsum poob los ntawm 1-2 qib, thiab kev sib tsoo yuav tsum tau kho, yog li qhov luaj li cas ntawm cov iav tuav cov npoo yuav tsum yog qhov siab tshaj plaws deformation ntawm lub iav tom qab carburizing quenching.Tseeb.Feem ntau, qhov kev hloov pauv siab tshaj plaws yog feem ntau cuam tshuam nrog cov txheej txheem thermal muaj peev xwm ntawm cov khoom siv, cov txheej txheem kev kho cua sov, cov qauv ntawm cov iav thiab cov duab ntawm cov geometry, yog li cov nyiaj seem yuav tsum tau txiav txim siab txog cov ntsiab lus saum toj no.
2. Lub iav yuav tsum muaj ib lub ru tsev nyob rau hauv lub hauv paus cag, thiab muaj peb yam:
2. 1 Los ntawm cov txheej txheem sib tsoo, nws yuav tsum muaj qee cov hauv paus txiav hauv paus los ua lub luag haujlwm ntawm cov hniav.
2. 2 Tom qab lub iav yog quenched, qhov seem ntawm cov iav yog compressive, uas yog qhov zoo heev los txhim kho qhov khoov lub zog ntawm lub iav, thiab cov hauv paus hniav sib tsoo yuav tig qhov seem ntawm qhov kev ntxhov siab los rub cov kev ntxhov siab, uas yuav ua rau lub log hniav Lub zog tiv thaiv kev khoov yog txo los ntawm 17-25%.
2. 3 Los ntawm kev khoov lub zog ntawm lub log, nws yuav tsum muaj qee yam ntawm cov hauv paus hniav ntawm cov iav.Yog tias tsis muaj cov hauv paus hniav ntawm cov hauv paus hniav, cov kauj ruam ntawm cov hauv paus hniav yuav tsim cov kauj ruam, uas yuav ua rau kom loj dua Cov kev ntxhov siab concentration, uas cuam tshuam rau lub peev xwm los tiv thaiv kev khoov ntawm cov iav.
3. 3 Asymptom ntev ntawm lub rear iav
Nws yuav tsum tau ntev txaus, vim hais tias cov hauv paus hniav yog rooted, nws muaj peev xwm ua rau lub sib tsoo ntev ntawm lub iav tom qab sib tsoo cov iav, uas ua rau ib tug txo nyob rau hauv qhov hnyav ntawm lub iav, yog li tsim kev co thiab suab nrov thaum lub sij hawm meshing txheej txheem. , thiab kuj txo cov load nqa lub peev xwm ntawm lub iav.Yog li ntawd, kev sib tsoo iav yuav tsum muaj ib txoj kab ntev txaus kom ntseeg tau tias kev ua haujlwm zoo ntawm cov iav.
Qhov zoo ntawm kev sib tsoo
1. Rau cov khoom siv kauv thiab quasi-bib iav, kev sib tsoo tuaj yeem ua tiav kev sib hloov, tsis tas yuav tsum tau siv, thiab lub zog ntawm cov hniav yuav tsum tau siv, kom qee cov nqi tuaj yeem hloov tau;
2. Kev sib tsoo tuaj yeem txhim kho qhov tseeb ntawm cov iav, txhim kho qhov tseeb ntawm qhov kis tau tus mob, thiab lub lapping tsuas tuaj yeem ua kom lub ntsej muag roughness ntawm lub iav;
3. Kev sib tsoo tuaj yeem txuag tau ntau yam khoom uas tsis tuaj yeem tho, txo ntau qhov pov tseg;
4. Rau ntau yam steels hauv tsev, tsis muaj qhov yuav tsum tau ua, ua rau muaj kev deformation ntau dhau tom qab kev kho cua sov, siv cov txheej txheem sib tsoo los kho qhov cuam tshuam, thiab cov hniav tshawb fawb tsis tuaj yeem ua tiav cov txiaj ntsig no;
5. Cov tuam txhab lag luam uas tau qhia txog kev sib tsoo tshuab hauv Suav teb tau ua tiav kev lag luam zoo heev;ntau lub tshuab ua kom zoo tshaj plaws kauv lub khob iav ntau lawm tau siv cov txheej txheem sib tsoo:
6. Nrog rau kev txhim kho kev sib tsoo efficiency, qhov nce hauv ntau lawm batch, cov nqi tsim khoom yuav raug txo kom tsawg.
Cov ntsiab lus
Nws yog undeniable tias kev sib tsoo yog qeeb dua lapping thiab kim dua lapping.
Piv txwv li, ib khub ntawm lub khob iav yuav tsum muaj ob lub tshuab sib tsoo, txhua lub iav yuav tsum tau ob feeb;lub lapping kuj yuav tsum tau ob feeb, tab sis tsuas yog ib lub tshuab lapping yuav tsum tau.Tsis tas li ntawd, lub tshuab sib tsoo cov nqi sib tsoo yog triple tus nqi ntawm lub tshuab lapping tus nqi.
Txawm li cas los xij, cov nqi pov tseg thiab cov neeg siv khoom tsis txaus siab siv rau thaj chaw tshwj xeeb tsuas yog 1% lossis tsawg dua, thaum cov khoom siv lapping ncav cuag 3-7%.Cov iav khib nyiab muaj cov nqi ntawm txhua qhov txheej txheem, tab sis kuj ntxiv cov nqi khoom, yog li hauv kev xav txog cov nqi pov tseg, kev sib tsoo muaj kev lag luam zoo dua.
Tsuas yog tsib xyoos dhau los, ob txoj kev ua tau zoo sib txawv ntawm tus nqi, muaj txiaj ntsig zoo rau cov hniav, tab sis niaj hnub no, kev tshawb fawb qhia tau hais tias nrog kev txhim kho ntawm cov cuab yeej siv tshuab, kev tsim cov tshiab sib tsoo log abrasives, semi-tiav zoo daim ntawv thov thiab ntau yam. lwm yam kev ua tiav tau tiav, thiab cov molars muaj lub neej yav tom ntej zoo heev, ua rau nws txoj kev ua haujlwm zoo nkauj heev.
