The article provides the results of a mathematical description of the distribution of contact stresses of a roll module with smooth rollers. Analysis of the developed models shows that when the rollers rotate. the maximum of the normal stress distribution diagram is displaced in the direction opposite to the movement of the material being processed; the displacement depends on the pro... https://www.bekindtopets.com/flash-offer-Bills-Big-Chain-Necklace-mega-offer/
