Indlela yokubala yomthwalo wetsheyini

Itsheyini ithwele umthwalo ifomula ngolu hlobo lulandelayo: Itsheyini yokuphakamisa ubunzima imitha ifomula?Impendulo: Ifomula esisiseko linani lamacandelo = ubude obupheleleyo (mm) ÷ 14. 8 mm = 600 ÷ 14. 8 = 40. 5 (amacandelo) Ubunzima becandelo ngalinye = Ithini ifomyula yokubala yamandla obunzima bomjikelo ityathanga lentsimbi?I-Chain breaking force Ukubalwa kwamandla aqhekezayo we-plate roller chain 1. Ubuncinci boxinzelelo lokuqhawula kwentsimbi ye-40Cr yi-S = 980N / mm2, ummandla omncinci we-cross-sectional wekhonkco enye yekhonkco kwiiyunithi ze-B (mm2), kunye Ubuncinane bamandla okuqhawuka kwekhonkco kwiiyunithi F (N).Ifomula F=S×B3.Ukubalwa kwekhonkco elinobukhulu be-10 kunye ne-pitch 80: B=15*10*2+12.5*10*2=550mm2F=980*550=539000N Ukubalwa kwetyathanga elinobunzima 16 kunye nepitch 80: B=15*16*2+12 .5*16*2=880mm2F=980*880=862400N Ukubala kwekhonkco I-16 kunye ne-pitch 120: B=23.5*16*2+22.5*16*2=1472mm2F=980*1472=1442560N
