Definitions

  • the invention relates to a clamping ring for the axial connection of cylindrical components which have annular flanges on their mutually opposite end faces, consisting of two or more clamping ring segments which can be connected by means of clamping screws, each of which has a groove radially overlapping the two opposite flanges on its inner circumference.
  • clamping rings are used, for example, to connect flange tubes. But they are also used for the axial connection of other components, for example cylindrical housings of screw extruders.
  • two or more housing parts which have radial flanges at their respective ends can be arranged axially one behind the other and connected to one another by appropriate clamping rings.
  • Annular flanges can also be provided between the flanges at the ends of the housings.
  • Two-part clamping rings are known, the clamping ring segments of which have radially protruding flange projections, so that the clamping ring segments can be contracted by clamping screws and thus pressed against the flange ends of the housings.
  • clamping rings are known from individual segments which are articulated in the manner of a link chain.
  • the contraction and pressing onto the flange connection is also carried out here using clamping screws.
  • the division of the clamping ring into a plurality of individual, articulated segments ensures that each of these segments receives a defined contact with the flange connection when the clamping ring is pulled together.
  • the object of the invention is therefore to create a clamping ring which, on the one hand, has a significantly simplified structure and, on the other hand, is less expensive to produce.
  • clamping ring segments each have at least one recess, which radially starts from the inner circumference and interrupts the groove.
  • two or more such recesses are provided spaced apart over the inner circumference of the clamping ring per clamping ring segment.
  • the shape and position of the recesses can vary from case to case.
  • This configuration of the clamping ring ensures that the clamping ring behaves in principle like a ring composed of individual segments.
  • the starting from the inner circumference Recesses cause a certain radial weakening of the clamping ring in these areas, so that when the clamping ring is contracted and pressed onto the flange connection, defined systems result which, overall, lead to an equalization of the applied clamping force.
  • the strength of the minimum cross-sectional area of the clamping ring segments in the area of the recesses should always be higher than that of the cross-sectional area of the clamping screw, so that if the clamping screw is tightened too much Tensioning screws form a predetermined breaking point.
  • the walls of the groove - seen in cross-section of the clamping ring - run conically towards the outer circumference and thus generate the desired axial preload force when the clamping screws are tightened.
  • the recesses themselves have, for example, a U-shape, as seen from the axial end face of the clamping ring.
  • the clamping ring segments each have open tangential recesses to the outer circumference, in which through-holes through the end faces of the clamping ring segments lying against one another are provided for receiving the tensioning screws.
  • the clamping screw nut protrudes beyond the outer circumference of the clamping ring.
  • clamping screw head is mounted on the bore of the clamping ring such that it can move in an angular manner. This can be achieved, for example, by correspondingly slightly conical bearing surfaces on the clamping ring head and the bore, or also by suitable intermediate washers.
  • the clamping ring shown in perspective consists of the clamping ring segments 1. These have bores 9 on their mutually facing end faces and recesses 8 on the outer circumference.
  • the tensioning screws 2, which have a tensioning screw nut 3 and a tensioning screw head 4, are passed through the bores 8.
  • the clamping ring segments are pulled towards each other and are thus placed radially on a flange connection, not shown.
  • the groove 5 provided on the inner circumference engages around the corresponding abutting flange on the components to be connected, e.g. the housing parts of an extruder.
  • each coaxial recesses 6 are provided over the inner circumference, which extend in the radial direction, interrupt the groove 5, and lead to a weakening of the material of the clamping ring in these areas.
  • the shape of the recesses can - as shown - be U-shaped.
  • the walls of the groove are conical, i.e. the diameter of the groove decreases in the direction of the outer diameter.

Abstract

L'invention concerne une bague de serrage servant au raccordement axial de pièces cylindriques qui comportent des brides annulaires sur leurs faces frontales opposées. Cette bague de serrage comprend deux segments (1) ou plus, reliés par des vis de serrage (2), chacun étant doté, sur sa circonférence intérieure, d'une gorge (5) s'étendant radialement sur les deux brides opposées. L'invention est caractérisée en ce que les segments (1) de la bague de serrage comporte chacun au moins un évidement (6) s'étendant radialement à partir de la circonférence intérieure et interrompant ainsi la gorge.
