Definitions

  • the subject matter of the invention is a shaped ring nut dedicated to bolt connections used to connect machine and device elements.
  • the object of the invention is to provide a shaped ring nut that prevents rotation of the nut, wherein the shaped ring has any shape (non-rounded), which allows to eliminate the degree of freedom being the rotation of the nut around its own axis.
  • the nut can be part of bolt connections used for connecting machine components and devices.
  • the essence of the solution lies in the fact that on one side on the frontal surface, the nut has an additional ring of any external shape allowing the elimination of the degree of freedom being the rotation of the nut around its own axis.
  • an additional ring of any shape is installed in a shaped hole made in one of the connected elements.
  • the outer shape of the additional ring is polygonal, in particular a quadrangle, a triangle, a regular polygon or an irregular polygon or a star polygon.
  • the outer shape of the additional ring is any oval.
  • the nut with an integrated shape ring can have an additional plastic ring placed inside to protect the connection against self-loosening.
  • the outer surface of the ring is inclined, as it allows tight installation of the nut in the shaped hole.
  • the height of the additional ring is smaller than the thickness of the connected element.
  • fig. 1 shows the isometric view from the side of the collar
  • fig. 2 shows a side view
  • fig. 3 shows the view and cross-section of the solution with an inclined surface
  • fig. 4 shows isometric view of an example of application
  • fig. 5-11 shows exemplary shapes of the outer ring
  • fig. 12-13 shows examples of how to insert the nut in the hole.
  • the nut shown in the drawing is shaped in such a way that, on one side of the frontal face 1, it has an additional ring 2 of any external shape 3 permitting the elimination of the degree of freedom being the rotation of the nut around its own axis.
  • the height h of the ring is smaller than the height of the connected element in which the nut is installed.
  • the outer shape 3 of the additional ring 2 is any regular polygon, especially a triangle (fig. 5), a quadrangle (fig. 6), a pentagon (fig. 7), a hexagon (fig. 8), an irregular polygon (fig. 9) or a star polygon (fig. 10).
  • the shaped nut with integrated shaped ring 2 can have an additional plastic ring placed inside to protect the connection against self- loosening.
  • the outer surface of the ring 2 is inclined, which allows tight installation of the nut in the shaped hole.
  • Connecting machine and device elements with a nut according to the invention consists in having at least two connected layers 6 with holes made, while in the last layer a shaped hole 7 is made in a shape corresponding to the shape of the shaped ring 2 of the nut, in which the nut with an additional shaped ring 2 will be installed. Then, in the hole made from the connection of bolted elements, a bolt is placed and in the last layer a nut with an additional shaped ring is placed in the shaped hole.

Abstract

L'objet de l'invention est un écrou à bague façonnée dédié à des raccords boulonnés utilisés pour relier des éléments de machine et de dispositif. Selon l'invention, l'essence de la solution réside dans le fait que sur un côté sur la surface frontale, l'écrou présente une bague supplémentaire de n'importe quelle forme externe permettant de supprimer le degré de liberté qui est la rotation de l'écrou autour de son propre axe. Une bague supplémentaire de n'importe quelle forme est installée dans un trou façonné ménagé dans l'un des éléments raccordés. La forme extérieure de la bague supplémentaire est n'importe quel polygone régulier, en particulier un triangle, un quadrilatère, un pentagone, un hexagone, un polygone irrégulier, un polygone en étoile ou la forme extérieure de la bague supplémentaire est n'importe quel ovale.
