Description

Klemmring zum axialen Verbinden von zylindrischen Bauteilen Clamping ring for the axial connection of cylindrical components

Die Erfindung betrifft einen Klemmring zum axialen Verbinden von zylindrischen Bauteilen, die an ihren einander gegenüberliegenden Stirnseiten ringförmige Flansche aufweisen, bestehend aus zwei oder mehr durch Spannschrauben verbindbaren Klemmringsegmenten, die jeweils an ihrem Innenumfang eine die beiden gegenüberliegenden Flansche radial übergreifende Nut aufweisen.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.

Derartige Klemmringe dienen beispielsweise zum Verbinden von Flanschrohren. Sie werden aber auch eingesetzt zum axialen Verbinden von anderen Bauteilen, und zwar beispielsweise von zylindrischen Gehäusen von Schneckenextrudern.Such 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.

Hierbei können je nach Anforderung an die Extrudereigenschaften zwei oder mehr Gehäuseteile, die an ihren jeweiligen Enden radiale Flansche aufweisen, axial hintereinander angeordnet und durch entsprechende Klemmringe miteinander verbunden werden. Zwischen den Flanschen an den Enden der Gehäuse können dabei auch noch ringförmige Flansche vorgesehen sein.Depending on the requirements of the extruder properties, 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.

Da in den Extrudern mit sehr hohen Drucken gearbeitet wird, wirken auf die Flanschverbindungen und damit die Klemmriπge erhebliche Kräfte ein.Since very high pressures are used in the extruders, considerable forces act on the flange connections and thus on the clamping rings.

Bekannt sind zweigeteilte Klemmringe, deren Klemmringsegmente radial abstehende Flanschansätze aufweisen, so dass durch Spannschrauben ein Zusammenziehen der Klemmringsegmente und damit ein Anpressen an die Flanschenden der Gehäuse möglich ist.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.

Beim Zusammenziehen und Anpressen der Klemmringsegmente kann es über den Umfang dieser zu Verformungen des Klemmringes mit Undefinierten Anlagen an den Flanschen kommen. Damit ergeben sich unterschiedliche Klemmkräfte über den Umfang gesehen, die unter Umständen zu Undichtigkeiten an der Flanschverbindung bei hohen Drucken führen können.When the clamping ring segments are pulled together and pressed on, the circumference of these segments can deform the clamping ring with undefined systems on the flanges. This results in different clamping forces over the circumference, which under certain circumstances can lead to leaks at the flange connection at high pressures.

Um die Klemmkräfte und damit die Anlage des Klemmriπges an den Flanschen zu verbessern, sind aus einzelnen Segmenten, die in Art einer Gliederkette gelenkig miteinander verbunden sind, bestehende Klemmringe bekannt. Das Zusammenziehen und Anpressen an die Flanschverbindung erfolgt auch hierbei über Spannschrauben. Durch die Aufteilung des Klemmringes in eine Mehrzahl von einzelnen, gelenkig miteinander verbundenen Segmenten wird erreicht, dass jedes dieser Segmente beim Zusammenziehen des Klemmringes eine definierte Anlage an der Flanschverbindung erhält.In order to improve the clamping forces and thus the abutment of the clamping ring on the flanges, existing 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.

Aufgrund der hohen aufzunehmenden Drucke sind diese gegliederten Klemmringe sehr aufwendig in der Herstellung und insbesondere sehr kostenintensiv.Due to the high pressures to be absorbed, these articulated clamping rings are very complex to manufacture and, in particular, very cost-intensive.

Aufgabe der Erfindung ist daher die Schaffung eines Klemmringes, der einerseits einen wesentlich vereinfachteren Aufbau aufweist und andererseits kostengünstiger herzustellen ist.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.

Gelöst wird diese Aufgabe - bei einem Klemmring der im Oberbegriff des Patentanspruchs 1 genannten Art - erfindungsgemäß dadurch, dass die Klemmringsegmente jeweils mindestens eine radial vom Innenumfang ausgehende, die Nut unterbrechende, Ausnehmung aufweisen.This object is achieved - in the case of a clamping ring of the type mentioned in the preamble of patent claim 1 - according to the invention in that the clamping ring segments each have at least one recess, which radially starts from the inner circumference and interrupts the groove.

Vorzugsweise sind je Klemmringsegment zwei oder mehr derartige Ausnehmungen im Abstand über den IrYnenumfang des Klemmringes verteilt vorgesehen. Die Ausnehmungen können in der Form und ihrer Lage von Fall zu Fall unterschiedlich sein.Preferably, 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.

Durch diese Ausgestaltung des Klemmringes wird erreicht, dass sich der Klemmring im Prinzip wie ein aus einzelnen Segmenten zusammengesetzter Ring verhält. Die vom Innenumfang ausgehenden Ausnehmungen bewirken eine gewisse radiale Schwächung des Klemmringes in diesen Bereichen, so dass sich beim Zusammenziehen und Anpressen des Klemmringes an die Flanschverbindung für die einzelnen Teilbereiche definierte Anlage ergeben, die insgesamt zu eine Vergleichmäßigung der aufgebrachten Spannkraft führen.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.

Während bei bekannten, aus Klemmringsegmenten bestehenden Klemmringen, ein großer Teil der durch die Spannschrauben eingebrachten Vorspannkräfte zur Verformung des Klemmringen notwendig ist, werden diese bei der erfindungsgemäßen Lösung zum überwiegenden Teii für die Aufbringung der die eigentliche Verspannuπg bewirkenden Axialkräfte genutzt.While in known clamping ring segments consisting of clamping ring segments, a large part of the pretensioning forces introduced by the clamping screws is necessary for the deformation of the clamping rings, in the solution according to the invention these are mainly used for the application of the axial forces causing the actual tensioning.

Um eine Überbelastung des durch die Ausnehmungen radial in diesen Bereichen geschwächten Klemmringes beim Anziehen der Spannschrauben zu vermeiden, soll die Festigkeit der minimalsten Querschnittsfläche der Klemmringsegmente im Bereich der Ausnehmungen immer höher sein als die der Querschπittsfläche der Spannschraube, so dass bei einem zu starken Anziehen der Spannschrauben diese eine Sollbruchstelle bilden.In order to avoid overloading the clamping ring, which is radially weakened by the recesses in these areas, when tightening the clamping screws, 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.

Zur Verbesserung der Anlage des Klemmringes an den Flanschen verlaufen die Wände der Nut- im Querschnitt des Klemmringes gesehen - konisch zum Außenumfang hin und erzeugen somit beim Anziehen der Spannschrauben die gwünschte axiale Vorspannkraft.To improve the abutment of the clamping ring on the flanges, 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.

Die Ausnehmungen selbst weisen - von der axiaien Stirnseite des Klemmringes her gesehen - beispielsweise eine U-Form auf.The recesses themselves have, for example, a U-shape, as seen from the axial end face of the clamping ring.

Die Klemmringsegmente weisen im Bereich ihrer miteinander verbindbaren Enden jeweils zum Außenumfang offene tangential verlaufende Ausnehmungen auf, in denen durch die Stirnseiten der aneinander liegenden Klemmringsegmente hindurchgehende Bohrungen zur Aufnahme der Spannschrauben vorgesehen sind.In the area of their interconnectable ends, 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.

Durch diese Ausgestaltung werden die Vorspannkräfte beim Anziehen der Spannschrauben direkt in die Klemmringsegmente eingeleitet. Zur Verbesserung der Aπgriffsmöglichkeit eines Werkzeuges an der Spannschraube ragt die Spannschraubenmutter über den Außenumfang des Klemmringes hervor.With this configuration, the pretensioning forces are introduced directly into the clamping ring segments when the clamping screws are tightened. To improve the ability of a tool to grip the clamping screw, the clamping screw nut protrudes beyond the outer circumference of the clamping ring.

Vorteilhaft ist es ferner, wenn der Spannschraubenkopf winkelbeweglich an der Bohrung des Klemmringes gelagert ist. Die kann beispielsweise durch entsprechend leicht konisch ausgebildete Auflageflächen am Spannringkopf und der Bohrung oder auch durch geeignete Zwischenscheiben erreicht werden.It is also advantageous if the 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.

Die Erfindung soll nachfolgend anhand eines Ausführungsbeispieles und einer vereinfachten Prinzipzeichnung erläutert werden.The invention will be explained below using an exemplary embodiment and a simplified schematic diagram.

Der perspektivisch dargestellt Klemmring besteht aus den Klemmringsegmenten 1. Diese weisen an ihren einanderzugekehrten Stirnseiten Bohrungen 9 auf und Ausnehmungen 8 am Außenumfang. Durch die Bohrungen 8 sind die Spannschrauben 2 geführt, die eine Spannschraubenmutter 3 und einen Spannschraubenkopf 4 aufweisen. Durch Anziehen der Spannschrauben werden die Klemmringsegmente aneinander gezogen und legen sich damit radial an einer nicht dargestellten Flanschverbindung an. Hierbei umgreift die am Innenumfang vorgesehene Nut 5 die entsprechenden aneinanderstoßenden Flansch an den zu verbindenden Bauteilen, z.B. den Gehäuseteilen eines Extruders. Vom Innenumfang ausgehend sind über den Innenumfang verteilt vier koaxial verlaufende Ausnehmungen 6 vorgesehen, die sich in radialer Richtung erstrecken, die Nut 5 unterbrechen, und zu einer Materialschwächung des Klemmringes in diesen Bereichen führen. Die Form der Ausnehmungen kann - wie dargestellt - u-förmig sein. Die Wän ie der Nut sind konisch ausgebildet, d.h. der Durchmesser der Nut vermindert sich in Richtung auf den Außendurchmesser. 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. By tightening the clamping screws, the clamping ring segments are pulled towards each other and are thus placed radially on a flange connection, not shown. Here, 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. Starting from the inner circumference, four 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.
