Ifomula yokubala umthwalo weketanga

Ifomula yokubala umthwalo weketanga ilandelayo: Ifomula yokubala isisindo semitha yokuphakamisa isisindo seketanga? Impendulo: Ifomula eyisisekelo inani lezingxenye = ubude obuphelele (mm) ÷ 14. 8 mm = 600 ÷ 14. 8 = 40. 5 (izingxenye) Isisindo sengxenye ngayinye = Iyini ifomula yokubala yamandla okudonsa eketanga lensimbi eliyindilinga? Amandla okuphula iketanga Ukubalwa kwamandla okuphula eketanga le-roller plate 1. Ukucindezeleka okuncane kokuphula kwensimbi engu-40Cr yi-S=980N/mm2, indawo encane yokunqamula yesixhumanisi seketanga elilodwa ikuyunithi ze-B (mm2), kanti amandla okuphula amancane eketanga akumayunithi e-F (N). Ifomula F=S×B3. Ukubalwa kweketanga elinobukhulu obungu-10 kanye ne-pitch engu-80: B=15*10*2+12. 5*10*2=550mm2F=980*550=539000N Ukubalwa kweketanga elinobukhulu obuyi-16 kanye nephimbo 80: B=15*16*2+12 .5*16*2=880mm2F=980*880=862400N Ukubalwa kweketanga elinobukhulu obuyi-16 kanye nephimbo 120: B=23. 5*16*2+22. 5*16*2=1472mm2F=980*1472=1442560N
