Cov txiaj ntsig ntawm cov iav tawv thiab khib hniav
Ua yeeb yamKev kho mob saum npoo(xws li carburizing, carbonitrivate, nituction, induction harcees thiab racks yog ib qho kev ua tau zoo, thiab lub neej muaj peev xwm, thiab lub neej ua haujlwm, thiab lub neej thiab cov kev kho mob uas cuam tshuamsiab tawvrau cov hniav sib dhos thaum tswj hwm amuaj zog thiab tawv core, xa cov txiaj ntsig tseem ceeb tshaj plaws:
Cov txiaj ntsig (muaj feem xyuam rau ob qho tib si thiab racks):
Tseem ceeb txhim kho kev coj tsis kam:
Cov ntsiab tau zoo .Lub cev tawv tawv ua kom muaj zog ntau ntxiv (feem ntau hrc 58-62 lossis siab dua tawm tsamhnavtshwm sim los ntawm kev swb txhuam, dov txhuam, thiab tej peev xwm abrasives (hmoov av, paug) thaum nqus cov duab ntxau {}}
Zoo heevtxuas ntxiv cov kev pabcuam lub neejntawm ob lub zog thiab racks, tshwj xeeb tshaj yog nyob rau hauv cov nra hnyav, kev kub ceev, nres, nres, lossis hauv ib puag ncig tsis huv {}}
Txhim kho kom tsis kam rau pitting thiab spalling:
Hardness thiab tuscompressive residual kev ntxhov siabtsim los ntawm cov txheej txheem tawv tawv yooj yim txhim kho cov hniav tawm tsis kamHu rau kev nkees.
Txo pitting:Inhibits qhov tsim ntawm micro-tawg thiab pockmark-zoo li spalling (pitting) ntawm cov hniav nyob hauv cyclic kev tiv tauj kev ntxhov siab.
Tiv thaiv spalling:Txo qhov kev pheej hmoo ntawm tob spalling (loj chunks ntawm cov khoom tawg kom deb ntawm cov hniav tsis ua haujlwm), ib qho kev ua tsis taus hluav taws xob tsis ua haujlwm {}}
Nce load-nqa khoom muaj peev xwm:
Cov hniav tawv tawv tuaj yeem tiv thaivsiab dua kev ntxhov siab(Hertzian kev nyuaj siab) tsis muaj kev sib tw yas dhau los lossis ua ntej ua hauj lwm} Qhov no tso cai rau xa cov khoom xa tuaj thiab thauj khoom ntau dua .
Txhim kho cov qhab nia tiv thaiv:
Nyob rau hauv kev kub ceev, hnyav load, lossis tsis zoo lubrication lubrication tej yam kev mob, ib puag ncig cov dej kub tuaj yeem ua rau cov khoom siv hlau kom ua ke .
Cov kab mob tawv muaj qhov ntau melting taw tes thiab yog cov tiv taus yas ntxiv rau cov dej yas thiab cov nplaum nyob rau hauv kev hloov tsheb kub siab, yog liTxo txoj kev pheej hmoo ntawm kev sib tw.
Zoo dua Precision Lug:
Vim muaj kev txo qis, covDaim Ntawv Ua Haujlwm Thawj Cov Hniavntawm lub iav thiab cov khib tuaj yeem tswj tau kom muaj sijhawm ntev dua .
Qhov no yog qhov tseem ceeb rau cov ntawv thov uas xav tausiab txoj hauj lwm raug thiab backlash(e {. g {}}}}, cov cuab yeej siv tshuab, tiv thaiv kev ua yuam kev los ntawm kev coj .
Ua rau ntau cov kev cog lus kev cog lus:
Qhov muaj peev xwm thauj khoom-nqa tau qee zaum tuaj yeem tso cai rau kev tsim qauv ntawmme me, qhov hnyav duacov iav thiab cov khib poob thaum sib ntsib tib yam kev thauj khoom .
Cov txiaj ntsig ntxiv rau cov iav tawv nqaij tawv:
Txhim kho khoov li qaug zog qaug zog:
Tus hniav hauv pausCyclic Bending Kev Ntseeglub sij hawm meshing thiab muaj kev nquag ua kom qaug zog ua kom khov .
Qee txoj kev ua kom tawv (e {{{0} g}}}, carburizing, inducted hardened cov ntaub ntawv ntawm lub hauv paus, honce qhov khoov kev khoov rog dag zog ntawm lub hauv paus hniavthiab txo qhov kev pheej hmoo ntawm cov hniav breaky .
Txhim khu cov duab smoothness:
High-hardness, siab-precision hniav chaw ua rausmoother, quietermeshing thiab hwj chim kis, txo kev co thiab cov suab nrov .
Cov kev txiav txim siab ntxiv thiab cov txiaj ntsig tshwj xeeb rau txoj kev tawv nqaij tawv tawv:
Chaw Nyob Ntev Hnav:
Racks feem ntau yog ntev, thiab lawv cov hniav sib luag ua haujlwm thaum lub sijhawm ua haujlwm. qhov chaw tawv tawv ua kom muaj zogtag nrho cov hniav ua kom tau zoo flank muaj cov ris tsho zoo, tiv thaiv hauv zos ntev dhau los uas tuaj yeem ua rau kis tsis tau lossis poob ntawm txoj kev ua haujlwm raug {}}
Tsis kam ua cov chaw thau khoom tsis zoo:
Hauv qee cov ntawv thov (e {{{{0} g .zos kev nyuaj siab.
Pab txhawb kev kho thiab txo qis hloov tus nqi:
Racks feem ntau loj dua, ntev dua, thiab kim dua li lawv cov txiv mating .} kev txhim kho khib txoj kev tiv thaivtseem ceeb dua kev hloov nws lub sijhawm hloov, Txo cov nqi txij nkawm thiab downtime . Nyob rau hauv sib piv, hloov ib pinion, hloov ib qho yooj yim thiab tsawg dua.
Ntsiab lus:
Iav Hniav Kev tawv tawv:Cov hom phiaj tseem ceeb yogHnav tsis kam, pitting tsis kam, khoov zog qaug zog, muaj peev xwm thauj tau ntxiv, ua kom haum, thiab ua haujlwm smoothness{{0.} Tsom yog ntawm tus hniav flank thiab paus .

Cov kev txiav txim tseem ceeb:
Case:Cov ntaub ntawv qhov tob yuav tsum tau ua tib zoo tsim qauv raws li module, thiab hom (cuam tshuam cov khoom lag luam xav tau qhov kev pheej hmoo siab heev tob dhau yuav ua rau brittleness .
Cov tub ntxhais muaj zog:Nto hardening presupposes tusCov tub ntxhais tuav tau lub zog txaus thiab tawv(feem ntau ua tiav los ntawm quenching thiab tempering) los txhawb cov ntaub ntawv tawv thiab tiv thaiv kev cuam tshuam thauj khoom, tiv thaiv kev puas tsuaj britture {}}
Precision tswj:Cov txheej txheem tawv tawv tuaj yeem ua rau distortion . yog li ntawd,Tom ntej ua haujlwm (e {{{0} g .}}, sib tsoo)feem ntau yog qhov tseem ceeb rau lub siab-precision zog thiab racks kom ntseeg tau tias tus hniav kawg thiab cov txheej txheem tseeb.
Xaiv cov txheej txheem:
Carburizing / carbonitriding:Haum rau lub zog thiab hnyav thauj racks xav tauLub Zog Sib Txawv, Siab thauj khoom muaj peev xwm, thiab qib khoov rau lub zog(e {. g {}}}}}}}}, cua cov khoom kis tau, cua tshuab, loj tshuab cov cuab yeej siv).
Nitrivider:Haum rau cov ntawv thov yuav tsum tausiab hardness, siab hnav tsis kam, tsawg kawg distortion, thiab corrosion tsis kam, qhov twg load muaj peev xwm los yog hauv paus dabtsi yog khoov zog yuav tsum tau ua kom muaj huab (e {}
