Description
Gebiet der ErfindungField of the invention
Die Erfindung betrifft ein ringförmiges, axiales Sicherungselement zum axialen Sichern eines Bauteils auf einer Welle oder in einer Bohrung mit mindestens einer konischen Flanke, das in eine Ringnut in der Welle oder der Bohrung mit mindestens einer konischen Nutflanke einsetzbar ist.The invention relates to an annular, axial securing element for axially securing a component on a shaft or in a bore with at least one conical flank, which can be inserted into an annular groove in the shaft or the bore with at least one conical groove flank.
Hintergrund der ErfindungBackground of the invention
Derartige ringförmige, axiale Sicherungselemente, insbesondere ein solcher Sicherungsring, sind in der
Für Wellen oder Bohrungen mit einem Durchmesser größer als 150 mm sind diese bekannten Keilringe nicht geeignet, so dass die axiale Sicherung von Bauteilen auf Wellen oder in Bohrungen mit größeren Durchmessern als 150 mm mittels Wellenmuttern bzw. Nutmuttern erfolgen muss, wenn eine formschlüssige Sicherung notwendig ist. Insbesondere bei Durchmessern größer als 1120 mm, wie sie bei Wellen in Windkraftanlagen vorkommen, sind Sonderprodukte nötig, da so große Wellenmuttern und Nutmuttern nicht genormt sind. Die dazu gehörigen Wellengewinde sind teuer, kompliziert herzustellen und schlecht zu prüfen.For waves or holes with a diameter greater than 150 mm, these known wedge rings are not suitable, so that the axial securing of components on shafts or in holes with diameters larger than 150 mm must be done by means of shaft nuts or locknuts, if a positive locking is necessary , In particular, with diameters greater than 1120 mm, as they occur in waves in wind turbines, special products are necessary because such large shaft nuts and locknuts are not standardized. The associated shaft threads are expensive, difficult to manufacture and difficult to test.
Zwar lassen sich Press- und Schrumpfverbände auch für derartig große Durchmesser herstellen, jedoch bieten diese nur eine kraftschlüssige Verbindung.Although press and shrink bandages can also be produced for such large diameters, however, they offer only a frictional connection.
Aufgabe der ErfindungObject of the invention
Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, ein ringförmiges, axiales Sicherungselement in der Art eines Keilrings vorzuschlagen, das einfach herzustellen ist, eine formschlüssige Verbindung auch bei Wellen oder Bohrungen großen Durchmessers gewährleistet und dabei den Ausgleich axialer Toleranzen zu erreichen gestattet.Against this background, the present invention seeks to propose an annular, axial securing element in the manner of a wedge ring, which is easy to produce, ensures a positive connection even with large diameter shafts or holes and thereby allows to achieve the compensation of axial tolerances.
Zusammenfassung der ErfindungSummary of the invention
Die Lösung dieser Aufgabe besteht bei einem ringförmigen, axialen Sicherungselement zum axialen Sichern eines Bauteils auf einer Welle oder in einer Bohrung darin, dass das Sicherungselement wenigstens an einer Stelle seines Umfangs quergeteilt ist und sich in diesem Bereich mittels einer Schraubenanordnung in der Ringnut einer Welle oder einer Bohrung radial spreizen oder zusammenziehen und dadurch in Richtung des zu sichernden Bauteils axial verschieben lässt.The solution to this problem consists in an annular, axial securing element for axially securing a component on a shaft or in a hole therein that the securing element is transversely divided at least at one point of its circumference and in this area by means of a screw arrangement in the annular groove of a shaft or radially spread or contract a bore and thereby allows to move axially in the direction of the component to be secured.
Dadurch, dass das Sicherungselement mittels einer Schraubenanordnung radial spreizbar oder zusammenziehbar ist, ist eine formschlüssige Verbindung des Sicherungselements mit der Welle oder der Bohrung gegeben, die besonders für Wellen oder Bohrungen mit großem Durchmesser, beispielsweise größer als 1120 mm, geeignet ist.Characterized in that the securing element by means of a screw arrangement is radially spreadable or contractible, a positive connection of the securing element with the shaft or the bore is given, which is particularly suitable for waves or holes with a large diameter, for example greater than 1120 mm.
Durch das radiale Verspannen des erfindungsgemäßen Sicherungselements mittels einer Schraubenanordnung wird eine axiale Verschiebung des Sicherungselements entlang seiner konischen Flanke und der entsprechenden Nutflanke der Ringnut bewirkt, wodurch das Bauteil auf der Welle oder in einer Bohrung axial durch Formschluss gespannt wird und axiale Toleranzen ausgeglichen werden.By the radial clamping of the securing element according to the invention by means of a screw arrangement, an axial displacement of the securing element along its conical flank and the corresponding groove flank of the annular groove is effected, whereby the component is axially clamped on the shaft or in a bore by positive engagement and axial tolerances are compensated.
Vorzugsweise ist das Sicherungselement an zwei Bereichen seines Umfangs, diametral gegenüberliegend quergeteilt ausgebildet, wobei entweder je eine Schraubenordnung in den beiden quer geteilten Bereichen des Sicherungselements oder in dem einen quer geteilten Bereich eine Gelenkverbindung und in dem diametral gegenüberliegenden Bereich die Schraubenanordnung vorgesehen sein können.Preferably, the securing element is formed on two regions of its circumference, diametrically opposite transversely divided, either a screw order in the two transversely divided areas of the fuse element or in a transversely divided area a hinge connection and in the diametrically opposite region, the screw arrangement can be provided.
Für die Montage in einer Ringnut in einer Welle kann sich das Sicherungselement durch wenigstens eine Zugschraube zusammenziehen lassen, während für die Montage in einer Ringnut in einer Bohrung das Spreizen durch wenigstens eine Druckschraube erfolgen kann.For mounting in an annular groove in a shaft, the securing element can contract by at least one lag screw, while for mounting in an annular groove in a bore spreading can be done by at least one pressure screw.
Die eingangs erwähnte Aufgabe wird des Weiteren durch die Verwendung des vorstehend definierten Sicherungselements zum axialen Sichern mit Formschluss von Ringen oder Naben auf Wellen mit großem Durchmessern über 1.000 mm und auch durch die Verwendung von zwei axial beabstandeten Sicherungselementen zum axialen Sichern und Positionieren eines dazwischen angeordneten Bauteils gelöst.The above-mentioned object is further achieved by the use of the above-defined securing element for axial securing with form-fitting rings or hubs on shafts with large diameters over 1,000 mm and also by the use of two axially spaced securing elements for axially securing and positioning a component arranged therebetween solved.
Wird nur ein Sicherungselement verwendet, so muss die Welle oder die Bohrung einen radialen Absatz aufweisen, gegen den sich das zu sichernde Bauteil mittels des Sicherungselements verspannen lässt. In diesem Fall ist nur ein Ausgleich von axialen Toleranzen des Bauteils möglich. If only one securing element is used, then the shaft or the bore must have a radial shoulder against which the component to be secured can be clamped by means of the securing element. In this case, only a compensation of axial tolerances of the component is possible.
Wird das Bauteil auf der Welle oder in der Bohrung durch zwei axial beabstandete Sicherungselemente fixiert, so ist kein Bund oder Absatz an der Welle oder in der Bohrung erforderlich und das Bauteil lässt sich mit Bezug auf die Welle oder Bohrung axial positionieren, indem die axial beabstandeten Sicherungselemente unterschiedlich tief in die entsprechenden Nuten hineingezogen oder in sie gespreizt werden.If the component is fixed on the shaft or in the bore by means of two axially spaced securing elements, then no collar or shoulder on the shaft or in the bore is required and the component can be axially positioned with respect to the shaft or bore by axially spaced apart Fastening elements are pulled into different depths in the corresponding grooves or spread in it.
