Chain load xam cov mis

Cov qauv ntawm cov saw load-bearing yog raws li nram no: Lifting chain meter hnyav xam mis?Teb: Cov qauv hauv paus yog cov naj npawb ntawm ntu = tag nrho qhov ntev (mm) ÷ 14. 8 mm = 600 ÷ 14. 8 = 40. 5 (segments) Qhov hnyav ntawm txhua ntu = Dab tsi yog cov qauv kev suav rau lub zog tensile ntawm lub voj voog. hlau saw?Chain breaking force Kev suav ntawm kev sib tsoo ntawm cov phaj rau cov saw hlau 1. Qhov tsawg kawg nkaus kev ntxhov siab ntawm 40Cr steel yog S = 980N / mm2, qhov tsawg kawg nkaus ntawm qhov sib txuas ntawm ib qho txuas txuas yog nyob rau hauv B units (mm2), thiab Qhov tsawg kawg nkaus tawg quab yuam ntawm cov saw yog nyob rau hauv F units (N).Formula F = S × B3.Kev suav cov saw nrog tuab 10 thiab pitch 80: B = 15 * 10 * 2 + 12.5 * 10 * 2 = 550mm2F = 980 * 550 = 539000N Kev suav cov saw nrog tuab 16 thiab suab 80: B = 15 * 16 * 2 + 12 .5 * 16 * 2 = 880mm2F = 980 * 880 = 862400N Chain suav nrog thickness 16 thiab pitch 120: B = 23.5 * 16 * 2 + 22.5 * 16 * 2 = 1472mm2F = 980 * 1472 = 1442560N
