Camshaft induction cua sov quenching zoo

Tom qab 8 cams txias los ntawm induction cua sov thiab immersion, qhov tob thiab quenching hardness ntawm hardened txheej yog qhia nyob rau hauv daim duab 3. Nws tuaj yeem pom los ntawm Table 3 tias ob qhov ntsuas tau ua tau raws li cov kev xav tau ntawm daim ntawv qhia khoom. Nws tuaj yeem pom los ntawm qhov sib txawv ntawm qhov pom ntawm quenched ib feem ntawm lub cam tias cov txheej txheej hardened yog uniform thiab txoj hauj lwm yog lawm.

Tom qab lub camshaft yog quenched, tus nqi nce ntawm radial runout yog kuaj los ntawm 0.15mm, uas tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm cov txheej txheem tom ntej yam tsis muaj kev ncaj. Qhov kub ntawm qhov nruab nrab quenching yog nyob rau hauv thaj tsam ntawm 10 ° C-40 ° C, thiab quenched cam tsis muaj quenching tawg los ntawm kev tshuaj ntsuam fluorescent.
