Description
Изобретение относитс к энергомашиностроению и может быть использовано в гидротурбостроении дл соединени валов турбины и генератора .The invention relates to power plant construction and can be used in hydro turbine construction to connect turbine shafts and a generator.
Известен узел фланцевого соединени , преимущественно гидромамин, содержащий установленные в отверсти х фланцев цилиндрические втулки и расположенные в них с зазором болты с гайками С13.The known assembly of the flange joint, mainly hydromamine, contains cylindrical bushings installed in the holes of the flanges and bolts with C13 nuts arranged in them with a clearance.
Однако выполнение такой конструкции сложно в производстве, таю как установка втулок с плотной посадкой требует совместной расточки или рассверловки фланцев, что усложн ет технологию их изготовлени и сборки. Кроме того, недостатком конструкции | вл етс и то, что при передаче крут щего момента с вала на вал срезающие усили , действующие на втулки, распредел ютс неравномерно из-за наличи различНЕЛХ, в пределах пол допусков, зазоров между втулка и фланцами. Это снижает надежность работы соединени .However, such a construction is difficult to manufacture, as the installation of bushings with a tight fit requires joint boring or re-drilling of the flanges, which complicates the technology of their manufacture and assembly. In addition, the lack of design | It is also the fact that when the torque is transmitted from the shaft to the shaft, the shear forces acting on the bushings are unevenly distributed due to the presence of different HFC within the floor tolerances, gaps between the sleeve and the flanges. This reduces the reliability of the connection.
Цель изобретени - упрощение технологии изготовлени и повышение надежности работы узла.The purpose of the invention is to simplify the manufacturing technology and increase the reliability of the node.
Поставленна цель достигаетс тем, что во фланце, расположенном со стороны гаек болтов, выполнены цилиндрические расточки с кольцевыми опорными .поверхност ми, а на концах втулок - ответные расточкам цилиндрические выступы с опорными поверхност ми и втулки установлены в отверсти х этого фланца с за10 зором .The goal is achieved by the fact that in the flange located on the side of the bolt nuts there are cylindrical bores with annular bearing surfaces, and at the ends of the sleeves, boring cylindrical protrusions with supporting surfaces and sleeves are installed in the holes of this flange with a gap.
На чертеже показан узел фланцевого соединени , продольный разрез. The drawing shows the flange assembly, a longitudinal section.
Узел фланцевого соединени содержит установленные в отверсти х флан15 цев 1 и 2 цилиндрические втулки 3 и расположенные в них с зазором болты 4 с гайками 5, во фланце 1, расположенном со стороны гаек 5 болтов 4, выполнены цилиндрические расточки б The assembly of flange connection contains cylindrical bushings 3 installed in the flange holes 1 and 2 and the bolts 4 arranged in them with a gap, with nuts 5, in the flange 1 located on the side of the nuts 5 of the bolts 4, cylindrical bores b are made
20 с кольцевыми опорными поверхност ми 7, а на концах втулок 3 - ответные расточкам 6 цилиндрические выступы 8 с опорными поверхност ми 9, и втулки 3 установлены в отверсти х фланца 1 20 with annular support surfaces 7, and at the ends of the sleeves 3, cylindrical protrusions 8 with supporting surfaces 9, which respond to the bores 6, and the sleeves 3 are fitted in the holes of the flange 1
25 с зазором.25 with a gap.
При работе узла фланцевого соединени под действием крут щего момента в первую очередь выбираютс наименьшие зазоры, обусловленные рассеиванием размеров втулок 3 и от30During the operation of the flange joint assembly, under the action of the torque, the smallest gaps due to the dispersion of the dimensions of the sleeves 3 and from 30 are chosen first.
