Njira yowerengera kuchuluka kwa unyolo

Njira yowerengera kulemera kwa unyolo ndi motere: Njira yowerengera kulemera kwa mita ya unyolo? Yankho: Njira yoyambira ndi chiwerengero cha zigawo = kutalika konse (mm) ÷ 14. 8 mm = 600 ÷ 14. 8 = 40. 5 (zigawo) Kulemera kwa gawo lirilonse = Kodi chiŵerengero cha chiwerengero cha mphamvu yozungulira ndi yotani? unyolo wachitsulo? Chain breaking force Kuwerengera mphamvu yosweka ya unyolo wodzigudubuza 1. Kupanikizika kochepa kwachitsulo kwa 40Cr ndi S=980N/mm2, gawo locheperako la unyolo umodzi lili mu B mayunitsi (mm2), ndipo mphamvu yochepa yothyoka unyolo ili mu F mayunitsi (N). Fomula F=S×B3. Kuwerengera unyolo wokhala ndi makulidwe 10 ndi phula 80: B=15*10*2+12. 5*10*2=550mm2F=980*550=539000N Mawerengedwe a unyolo ndi makulidwe 16 ndi phula 80: B=15*16*2+12 .5*16*2=880mm2F=980*880=862400N kuwerengetsa makulidwe 16 ndi khwekhwe 120: B = 23. 5*16*2+22. 5*16*2=1472mm2F=980*1472=1442560N
