6.Mexanik hisobi

Gorizontal valsovkaning minamal diametri, (mm).

Valsovkaning ishlab chiqarish quvvati;

A – besh valli stanok uchun tajribalardan olingan koeffitsent kungaboqar mag‘izi uchun A=0,0174

D – val diametri D= 400 mm

L – val uzunligi L= 1250 mm

n – valning aylanishlari soni n= 140 ayl/min.

Danakdan tovar chiqishini 65% ga teng deb xisoblab valsovkaning ishlab chiqarish quvvati quyidagicha.
