Technical Specifications thiab Industry Practices for Gear Skiving Machine Implementation Standards

Raws li cov cuab yeej tseem ceeb rau precision iav machining, iav skiving tshuab 'kev siv cov qauv yog ncaj qha ntsig txog qhov raug, kev ntseeg tau, thiab kev pab cuam lub neej ntawm iav kis. Cov kev qhia tshwj xeeb nruj yog siv ob qho tib si thoob ntiaj teb thiab hauv tsev kom ntseeg tau tias kev ua haujlwm zoo ib yam. Cov qauv tseem ceeb suav nrog ISO, DIN, GB, thiab cov qauv kev lag luam xws li JB / T.
Hais txog geometric raug, lub iav skiving tshuab yuav tsum ua tau raws li ISO 230-1 cov kev cai dav dav rau cov cuab yeej siv tshuab geometric raug. Cov tsis tseem ceeb xws li axial runout thiab radial runout feem ntau yog tswj rau qib micron (piv txwv li, ± 2μm). Kinematic raug cov qauv yuav tsum tau spindle rotation raug kom ua tau raws li cov qauv teev nyob rau hauv ISO 230-2 los xyuas kom meej cov hniav meshing. Tsis tas li ntawd, GB / T 17421.1-2016, "Txoj Cai Tswjfwm rau Kev Tshuaj Xyuas Cov Cuab Yeej Siv Tshuab," qhia cov ncauj lus kom ntxaws txog qhov tseeb ntawm qhov chaw thiab rov ua dua ntawm cov iav skiving tshuab. Cov qauv high-end yuav tsum ua kom tau raws li qhov yuav tsum tau ua ntawm tsawg dua 0.005mm. Hais txog cov khoom siv thiab cov qauv txheej txheem, cov khoom tseem ceeb xws li cov ntxaiv thiab cov cuab yeej yuav tsum tau ua los ntawm cov hlau muaj zog hlau thiab ua tiav qhov tawv tawv ntawm HRC58-62 los ntawm cov txheej txheem kho cua sov (xws li carburizing thiab quenching). Lub tshuab lubrication yuav tsum ua kom tau raws li cov roj huv huv tau teev tseg hauv ISO 3448 (NAS qib 9 lossis siab dua) kom txo tau qhov cuam tshuam ntawm kev hnav ntawm qhov tseeb. Cov qauv kev nyab xeeb nruj me ntsis ua raws li ISO 13849-1, yuav tsum muaj lub sijhawm nres thaum muaj xwm txheej ceev tsawg dua 0.2 vib nas this thiab kev teeb tsa ntawm cov khoom siv tiv thaiv overload.
Hauv kev lag luam kev lag luam, German DIN 3960 tus qauv teeb tsa cov kev xav tau ntau dua rau cov hniav sib txawv (F Tsawg dua lossis sib npaug ntawm 12μm) thiab kev qhia cov hniav sib txawv (F Tsawg dua lossis sib npaug li 15μm) rau cov iav skiving tshuab machining involute iav, thaum lub tsev JB / T 8360{{5} automotive gears 2013. Nrog rau kev txhim kho ntawm kev tsim khoom ntse, tshiab - tiam iav skiving tshuab tau maj mam sib koom ua ke cov qauv ntsuas kev ua tau zoo tau teev tseg hauv ISO 230-4, optimizing machining stability los ntawm kev saib xyuas lub sij hawm ntawm kev co zaus (feem ntau txwv rau 50Hz). Kev siv nruj ntawm cov qauv no tsis yog tsuas yog qhov tseem ceeb rau kev ua haujlwm ntawm cov iav kis tau tus mob tab sis kuj tseem ceeb heev rau kev txhawb nqa kev loj hlob zoo hauv kev tsim khoom lag luam. Cov tuam txhab lag luam yuav tsum xyuas kom lawv cov cuab yeej txuas ntxiv ua kom tau raws li cov kev qhia tshwj xeeb los ntawm kev ntsuas tsis tu ncua (pom zoo txhua 2,000 teev) thiab cov qauv kev sib piv cov qauv.
