DIN 5402 yog hais txog tus qauv kev lag luam German uas qhia txog qhov ntev thiab kev ua siab ntev rau cov menyuam bearings. Tshwj xeeb tshaj yog, DIN 5402-1 cuam tshuam nrog cylindrical roller bearings thiab lawv cov khoom, thaum DIN 5402-3 npog koob rau cov menyuam bearings. Cov qauv no ua kom muaj kev sib haum xeeb hauv kev tsim khoom thiab kev sib hloov ntawm cov menyuam bearings siv nyob rau hauv ntau yam kev siv, xws li tshuab, tsheb, thiab aerospace sectors.
Tus qauv DIN 5402-3-1993 cuam tshuam rau cov kabmob dov, tshwj xeeb yog tsom rau cov koob dov. Hauv qab no yog qee cov ntsiab lus tseem ceeb ntawm tus qauv thiab cov ntsiab lus uas yuav tsum tau them sai sai rau thaum lub sijhawm tsim khoom:
1. Kev xaiv cov khoom siv
• Cov khoom tsim rau dov koob yuav tsum muaj lub zog siab, hnav tsis kam, thiab hardness zoo. Feem ntau, high-carbon chromium bearing steel (xws li 100Cr6) yog siv.
2. Dimensions thiab Tolerances
• Dimensional Accuracy: Txoj kab uas hla thiab ntev ntawm cov dov koob yuav tsum ua raws li cov lus qhia tshwj xeeb uas tau teev tseg hauv DIN 5402-3. High-precision machining cov cuab yeej thiab ntsuas cov cuab yeej yuav tsum tau.
• Form and Position Tolerances: Cylindricity thiab straightness ntawm cov dov koob yuav tsum tau xyuas kom tsis txhob deviations thiab hnav thaum lub sij hawm bearing.
3. Cov txheej txheem ntau lawm
• Cold Rolling and Cold Drawing: Dov koob feem ntau yog tsim los ntawm cov txheej txheem txias dov lossis txias txheej txheem kom ntseeg tau tias lawv qhov tseeb qhov tseeb thiab qhov chaw tiav.
• Txiav thiab sib tsoo: Qhov ntev thiab txoj kab uas hla ntawm cov dov koob yuav tsum tau machined precisely. Txiav thiab sib tsoo cov txheej txheem yuav tsum tau tswj nruj me ntsis kom ntseeg tau tias qhov ntev ntev yog nyob rau hauv cov qauv yuav tsum tau ua.
• Kev kho cua sov: Cov khoom siv yuav tsum tau kho cua sov kom tsim nyog kom ua tau raws li qhov xav tau ntawm hardness thiab toughness.
4. Nto Zoo
• Surface Finish: Lub npoo ntawm cov dov koob yuav tsum muaj qhov ua tiav siab kom txo tau kev sib txhuam thiab hnav. Qhov no feem ntau ua tiav los ntawm kev sib tsoo zoo thiab polishing.
• Deg Defects: Qhov saum npoo yuav tsum tsis muaj kab nrib pleb, pits, khawb, thiab lwm yam tsis xws luag. Kev tswj hwm nruj thiab kev tshuaj xyuas yog xav tau thaum lub sijhawm tsim khoom.
Cov ncauj lus kom ntxaws txog thaum tsim khoom
• Kev tuav cov khoom siv: xyuas kom muaj kev siv cov khoom zoo uas ua tau raws li cov txheej txheem thiab ua raws li kev kho cua sov kom tsim nyog.
• Precision Machining: Siv cov cuab yeej ua haujlwm siab rau kev txiav thiab sib tsoo dov koob, kom ntseeg tau tias qhov ntev thiab daim ntawv kam rau ua raws li cov qauv.
• Kev Kho Ntog: Ua kom zoo sib tsoo thiab polishing kom ua tiav qhov chaw siab thiab tsis muaj qhov tsis xws luag.
• Kev Tswj Xyuas Zoo: Ua nruj me ntsis kev soj ntsuam zoo ntawm txhua theem tsim khoom, suav nrog kev ntsuas qhov ntev thiab kev tshuaj xyuas saum npoo, kom ntseeg tau tias cov khoom ua tau raws li cov qauv.
Los ntawm kev ua raws li cov kev ntsuas no, dov koob tsim tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm DIN 5402-3-1993 tus qauv, muaj lub zog siab, hnav tsis kam, qhov zoo ntawm qhov tseeb, thiab qhov zoo ntawm qhov chaw, yog li ua tiav cov kev xav tau ntawm cov kabmob dov.
