Feem ntau koj yuav hnov cov txheej txheem sib txawv los ntawm kev siv tshuabcov iav bevel, uas suav nrog cov iav bevel ncaj, cov iav bevel sib dhos, cov iav crown lossis cov iav hypoid.
Qhov ntawd yog Milling, Lapping thiab Grinding. Milling yog txoj hauv kev yooj yim los ua qhovcov iav bevelTom qab ntawd tom qab milling, qee tus neeg siv khoom xaiv lapping, qee tus neeg siv khoom xaiv kev sib tsoo. Qhov txawv yog dab tsi?
Kev lapping yog ib qho kev ua tiav, lub hom phiaj tseem ceeb tshaj plaws ntawm kev tshawb fawb cov hniav yog kom txo qhov suab nrov thiab txhim kho qhov kev sib cuag ntawm cov hniav iav. Lapping yog ib txoj kev ua tiav rau kev kho cov hniav me me thiab txhim kho qhov zoo ntawm qhov chaw. Vim yog qhov yuam kev los ntawm kev txiav milling lossis kev kho cua sov deformation ntawm cov kauj ruam dhau los, qhov tseeb ntawm meshing raug txo qis, lub hom phiaj ntawm cov hniav yog kom dim ntawm qhov chaw sib cuag ntawm lub log kom txhim kho cov yam ntxwv dov du ntawm cov hniav lwj, xyuas kom meej tias cov hniav log ntsiag to, txhim kho lub peev xwm ntawm tus neeg tuav.
Lapping yog ib qho me me ntawm cov txheej txheem txiav hlau, uas ua tiav los ntawm qhov ceev thiab lub zog cuam tshuam nrog qhov rov qab rau ntawm qhov chaw hniav. Yam tsawg kawg tus kws kho hniav xav kom txo qhov suab nrov, qib ntawm kev txo qhov suab nrov txawv nyob ntawm cov txheej txheem hniav txheej txheem thiab cov iav hauv qab pib mob. Kev txhim kho ntawm cov hniav mus rau suab nrov tuaj yeem ntsuas los ntawm ntau yam kev ntsuas siab. Cov hniav tshawb fawb kuj tsis tas yuav muaj peev xwm thauj khoom ntawm cov iav khub, los ntawm lwm lub kaum sab xis, uas yog, thaj chaw sib cuag thawj zaug ntawm cov hniav tsis ua puas lub log, nws yog qhov zoo tshaj plaws los txhim kho thaj chaw sib cuag tig.
Txawm hais tias lapping tsis tuaj yeem hloov kho kom raug rau cov iav khub zoo li txoj kev sib tsoo, txhim kho qib kev raug ntawmiav, tab sis los ntawm qhov chaw nyob tsim nyog tswj kev siv tshuab, torque tiag tiag tswj kev siv tshuab, thiab lwm yam, lossis tuaj yeem txhim kho thaj chaw sib cuag tig tau zoo. Piv txwv li, raws li cov txheej txheem xav tau, cov duab ntawm lub nruas hniav hauv cov hniav lossis qhov ntev ntawm cov hniav nce ntxiv, thiab thaj chaw sib cuag ntawm cov hniav me dua hauv qhov ntev ntawm kev sib cuag, qhov chaw thiab lub xeev deflection.
Vim li cas rau Lapping
1. Tus nqi ntawm kev kho hniav qis, tus nqi khoom siv qis dua, thiab nws yog qhov tseeb kom txo qhov suab nrov;
2. Yuav tsum siv lub iav sib txuas ua ke nrog cov hniav, tab sis qhov chaw ntawm cov hniav ntawm lub log loj thiab lub log me yog qhov zoo tshaj plaws.
3. Tom qab cov hniav yog cov iav kho cua sov, ob lub iav raug sib tsoo rau ib leeg, cov iav no tsis ua rau lub plhaub tawv puas tsuaj, thiab cov hniav sib xws, ua kom lub neej ntawm cov iav;
4. Rau tag nrho lub cev kis ntawm lub tsheb, qhov ceev tseem ceeb ntawm lub tsheb (qhov kis kawg) tsis tseem ceeb tom qab siv cov hniav sib tsoo, vim tias lub cev kis ntawm lub cev kis, xws li lub cev kis, thiab thoob plaws lub cev kis. Qhov tseeb ntawm lub tshuab tsis siab dhau;
5. Txawm tias muaj cov ntaub ntawv xa tuaj los xij, kev kho cua sov yog siv los siv kev tshawb fawb rau lapping, thiab tus nqi tsim khoom tsis siab dua li kev sib tsoo.
Kev Sib Tsoo:Qhov kev kho cua sov deformation raug tshem tawm tom qab cov hniav tawv, thiab txhim kho qhov precision ntawm cov iav thiab txhim kho qhov roughness ntawm cov hniav, thiab tseem yog raws li cov txheej txheem sib tsoo.
Cov Kev Cai Rau Cov Hniav Iav Ua Ntej Sib Tsoo
1. Kev sib npaug ntawm cov ntaiv yuav tsum sib npaug
Vim yog qhov deformation tom qab cov iav carbon quenching, qhov tseeb yuav tsum poob los ntawm 1-2 qib, thiab qhov sib tsoo yuav tsum tau kho, yog li qhov loj ntawm cov iav khaws cia ntug yuav tsum yog qhov deformation siab tshaj plaws ntawm cov iav tom qab carburizing quenching. Tseeb. Feem ntau, qhov sib txawv siab tshaj plaws yog feem ntau cuam tshuam nrog lub peev xwm ua haujlwm thermal ntawm cov khoom siv, cov txheej txheem kho cua sov, cov qauv ntawm cov iav thiab geometry ntawm geometry, yog li tus nqi seem yuav tsum xav txog cov yam saum toj no.
2. Lub iav yuav tsum muaj ib lub ru tsev nyob rau hauv lub hauv paus cag, thiab muaj peb qho laj thawj:
2. 1 Txij li thaum sib tsoo, yuav tsum muaj qee qhov txiav hauv paus kom ua lub luag haujlwm ntawm cov hniav.
2. 2 Tom qab lub iav raug tua, qhov kev ntxhov siab seem ntawm lub iav yog compressive, uas yog qhov zoo heev rau kev txhim kho lub zog khoov ntawm lub iav, thiab cov hauv paus hniav sib tsoo yuav tig qhov kev ntxhov siab seem ntawm qhov chaw kom rub qhov kev ntxhov siab, uas yuav ua rau lub log hniav Lub zog tiv thaiv kev khoov raug txo los ntawm kwv yees li 17-25%.
2. 3 Los ntawm lub zog khoov ntawm lub log, nws yog qhov yuav tsum muaj qee lub hauv paus ntawm lub hauv paus ntawm lub iav. Yog tias tsis muaj lub hauv paus ntawm lub hauv paus hauv paus, cov kauj ruam ntawm lub hauv paus yuav tsim cov kauj ruam, uas yuav ua rau muaj kev ntxhov siab ntau dua, uas cuam tshuam loj heev rau lub peev xwm tiv thaiv kev khoov ntawm lub iav.
3. 3 Qhov ntev ntawm lub iav nram qab tsis zoo
Nws yuav tsum ntev txaus, vim tias cov hauv paus hniav yog cag, nws muaj peev xwm ua kom qhov ntev ntawm lub iav tom qab kev sib tsoo ntawm lub iav, ua rau qhov hnyav ntawm lub iav txo qis, yog li tsim kev co thiab suab nrov thaum lub sijhawm meshing, thiab tseem txo qhov muaj peev xwm nqa khoom ntawm lub iav. Yog li ntawd, lub iav sib tsoo yuav tsum muaj kab ntev txaus kom ntseeg tau tias kev ua haujlwm du ntawm lub iav.
Cov Zoo ntawm Kev Sib Tsoo
1. Rau cov iav kauv thiab cov iav quasi-bib, kev sib tsoo tuaj yeem ua tiav kev sib pauv, tsis tas yuav siv lawm, thiab cov iav ntawm cov hniav yuav tsum tau siv, yog li qee tus nqi tuaj yeem rov ua dua;
2. Kev sib tsoo tuaj yeem txhim kho qhov tseeb ntawm lub iav, txhim kho qhov tseeb ntawm kev sib kis, thiab lub lapping tsuas yog tuaj yeem ua rau qhov roughness ntawm lub iav nce ntxiv;
3. Kev sib tsoo tuaj yeem txuag tau ntau yam khoom uas tsis tuaj yeem tho qhov, txo ntau qhov pov tseg;
4. Rau ntau cov hlau hauv tsev, tsis muaj qhov yuav tsum tau ua, ua rau muaj kev hloov pauv ntau dhau tom qab kev kho cua sov, siv cov txheej txheem sib tsoo los kho qhov cuam tshuam no, thiab cov hniav tshawb fawb tsis tuaj yeem ua tiav qhov cuam tshuam no;
5. Cov chaw tsim khoom iavCov neeg uas tau qhia txog kev siv tshuab sib tsoo hauv Suav teb tau ua tiav cov txiaj ntsig zoo rau kev lag luam; ntau lub tuam txhab tsim khoom siv iav sib tsoo tau siv cov txheej txheem sib tsoo:
6. Nrog kev txhim kho ntawm kev sib tsoo ua haujlwm, qhov nce ntawm cov khoom tsim tawm, tus nqi tsim khoom yuav raug txo qis heev
Sau luv luv
Nws tsis tuaj yeem tsis lees paub tias kev sib tsoo qeeb dua li lapping thiab kim dua li lapping.
Piv txwv li, ib khub lub iav cone xav tau ob lub tshuab sib tsoo, txhua lub iav xav tau ob feeb; lub lapping kuj xav tau ob feeb, tab sis tsuas yog xav tau ib lub tshuab lapping xwb. Tsis tas li ntawd, tus nqi sib tsoo ntawm lub tshuab sib tsoo yog peb npaug ntawm tus nqi lapping ntawm lub tshuab lapping.
Txawm li cas los xij, cov nqi pov tseg thiab cov lus tsis txaus siab ntawm cov neeg siv khoom siv rau thaj chaw tshwj xeeb tsuas yog 1% lossis tsawg dua, thaum cov khoom lapping ncav cuag 3-7%. Cov iav pov tseg muaj cov nqi ntawm txhua cov txheej txheem, tab sis kuj ntxiv cov nqi khoom siv, yog li ntawd 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 haujlwm sib txawv heev hauv tus nqi, zoo dua 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 khoom siv sib tsoo log tshiab, kev siv txoj kev ua tiav ib nrab thiab ntau lwm yam kev ua tiav tau ua tiav, thiab cov molars muaj yav tom ntej ci ntsa iab heev, ua rau nws yog txoj kev ua haujlwm zoo heev.
