Peb txhua tus paub tias cov cuab yeej siv tau tuaj yeem faib ua kev nrawm (ceev} 2}} m / s, chav siab siab {{ 4}}N/mm^2, impact load is not large), and high speed (speed 4-12m/s, bending torque, unit pressure 200-700N/mm^2), but different requirements Ntawm cov khoom lag luam cov khoom siv cov khoom siv thiab kev kho cua sov thiab lwm yam uas cuam tshuam. Koj puas paub, ntsig txog:
1. 20Cr carburising, quenching, tsis kub tempering HRC 56-62 rau kev kub ceev, siab, nruab nrab tus nqi, cuam tshuam iav.
2. Rau cov iav nrog me me circumferential ceev thiab nruab nrab chav tsev siab, 40Cr quenching thiab tempering, HB 220-250; rau cov iav nrog nruab nrab ncig nrawm thiab lub teeb cuam tshuam load, quenching, tempering, HRC40-50.
3. 45 Quenching, Kub Kub Tawv Sim, Hb 200-250}} siv rau kev ua kom nrawm; 1m / s nruab nrab siab, siab heev quenching; nto hardness hrc 52-58; Rau zog nrog cov siab tawv zoo xav tau thiab deformation me ntsis.
4. Sib nrug los ntawm cov lus hais saum toj no, kev siv hluav taws xob ntau zaus thiab hardness HRC52-58 yog siv nyob rau hauv rooj plaub uas deformation tseem tsawg heev tom qab kev kho cua sov.
