Yuav ua li cas xaiv qhov tob ntawm hardened txheej ntawm induction cua sov rauv quenched qhov chaw?

Qhov tob ntawm txheej hardened feem ntau txiav txim siab los ntawm kev ua haujlwm ntawm qhov quenched thiab seb nws puas yog av thaum siv.

1) Rau qhov chaw uas ua haujlwm nyob rau hauv kev sib txhuam, qhov tob ntawm txheej hardened feem ntau yog 1.5 ~ 2.0 hli, thiab qhov tob ntawm txheej hardened tuaj yeem loj dua, 3 mus rau 5 hli, yog tias nws xav tau hauv av tom qab hnav.

2) Qhov tob ntawm txheej hardened ntawm cov khoom raug extrusion thiab siab load yuav tsum yog 4 ~ 5mm.

3) Qhov tob ntawm txheej hardened ntawm txias dov spokes yuav tsum ntau tshaj 10mmo

4) Rau quenched qhov chaw raug rau alternating loads, thaum muaj kev ntxhov siab tsis dhau, qhov zoo hardened txheej qhov tob yuav yog 15% ntawm txoj kab uas hla ntawm ib feem; nyob rau hauv kev kub ntxhov siab, qhov zoo hardened txheej qhov tob yuav tsum ntau tshaj 20% ntawm txoj kab uas hla kom nce lub zog qaug zog ntawm ib feem.

5) Qhov tob ntawm txheej hardened ntawm lub xub pwg nyom los yog fillet feem ntau yuav tsum siab tshaj 1.5mmo

6) Rau shafts nrog cov kauj ruam raug torsion, lub hardened txheej yuav tsum tas mus li tag nrho ntev, txwv tsis pub lub torsional lub zog ntawm lub ncej yuav qis dua cov shafts uas tsis tau quenched los ntawm ib tug induction cua sov cua sov vim qhov cuam tshuam ntawm cov txheej txheem hardened ntawm kev hloov ntawm cov kauj ruam. .

Qhov tob ntawm txheej hardened ntawm quenched qhov chaw ntawm lub induction cua sov rauv yuav tsum muaj ib tug sab sauv thiab ib tug tsawg txwv ntau yam. Qhov kev hloov pauv dav dav yog 1 ~ 2mm. Piv txwv li, qhov tob ntawm txheej hardened yog 0.5 mus rau 1.0 hli, 1.0 mus rau 2.0 mm, 1.0 mus rau 2.5 mm, 2.0 rau 4.0 mm, 3.0 rau 5.0 mm, thiab hais txog. Lub hardness kuj tseem muaj qhov txwv siab thiab qis, xws li 56 ~ 64HRC, 52 ~ 57HRC, 50HRC, -45HRC, thiab lwm yam.
