Effect of Stochastics of Dimensional Parameters of Hauling Laminated Bushless Chain Elements of Improved Structure on Their Bearing Strength

摘要

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 K_m , for which the minimum, the most probable and the maximum values were determined. The formula for K_m 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.
