Ifomula yokubala yokulayisha iketango

Ifomula yokubala iketango elithwala umthwalo limi kanje: Ifomula yokubala yesisindo semitha yeketango?Impendulo: Ifomula eyisisekelo inombolo yamasegimenti = ubude obuphelele (mm) ÷ 14. 8 mm = 600 ÷ 14. 8 = 40. 5 (amasegimenti) Isisindo sesegimenti ngayinye = Ithini ifomula yokubala yamandla aqinile omjikelezo iketango lensimbi?Amandla okwephula iketango Ukubalwa kwamandla aphukayo weketango le-plate roller 1. Ingcindezi encane yokuphuka yensimbi engu-40Cr ngu-S=980N/mm2, indawo encane enqamula ingxenye yesixhumanisi seketango elilodwa ingamayunithi B (mm2), futhi ubuncane bamandla okuphuka kweketango ngamayunithi angu-F (N).Ifomula F=S×B3.Ukubalwa kweketango elinogqinsi 10 kanye nephiphu 80: B=15*10*2+12.5*10*2=550mm2F=980*550=539000N Ukubalwa kweketango elinogqinsi 16 kanye ne-pitch 80: B=15*16*2+12 .5*16*2=880mm2F=980*880=862400N Ukubala kweketanga ukujiya 16 kanye ne-pitch 120: B=23.5*16*2+22.5*16*2=1472mm2F=980*1472=1442560N
