Abstract
Высоконагруженное термозатягиваемое болтовое соединение, состоящее из соединяемых элементов и болта, отличающееся тем, что болт снабжен электронагревательными элементами, а геометрические и кинематические характеристики материала болта определяются соотношением:где Т- температура, необходимая для затяжки болта,Р- необходимое усилие затяжки болта,L- длина гладкой части тела болта,Lc - длина резьбовой части тела болта,α - коэффициент теплового расширения материала болта,δсм - смятие микронеровностей на контактирующих поверхностях,ξ - коэффициент, учитывающий уменьшения вытяжки за счет сжатия соединяемых деталей,FδН - площадь сечения гладкой части болта с учетом ослабления отверстиями под электронагревательные элементы,Е - модуль Юнга материала болта.A highly loaded thermally tightened bolt connection, consisting of connected elements and a bolt, characterized in that the bolt is equipped with electric heating elements, and the geometric and kinematic characteristics of the bolt material are determined by the ratio: where T is the temperature required to tighten the bolt, P is the required bolt tightening force, L- the length of the smooth part of the body of the bolt, Lc is the length of the threaded part of the body of the bolt, α is the coefficient of thermal expansion of the material of the bolt, δcm is crushing of microroughnesses on the contacting surfaces, ξ is the coe the coefficient taking into account the reduction of the hood due to compression of the parts to be joined, FδН is the cross-sectional area of the smooth part of the bolt, taking into account the attenuation by the holes for electric heating elements, E is the Young's modulus of the bolt material.
