Abstract
The distribution densities of dimensional parameters of a hauling laminated bushless chain of improved structure were investigated in this paper. The authors suggest calculating the non-uniform load of internal and external links plates by probability coefcient Km, for which the minimum, the most probable and the maximum values were determined. The formula for Km determination depending on plate size variety due to a gap random value Δ and plate elastic deformation value under permitted payload was obtained. The efect of stochastics of dimensional parameters of hauling laminated bushless chain elements on their bearing strength is proved.
