Abstract

In the present locking device for screw fastening, particularly for shaft couplings, the transmission elements (3) such as tongues, ring disks or membranes, arranged perpendicularly to the rotation axis between the two coupling parts, are fastened by screw assemblies alternatingly to the flanges (8) of both coupling parts. The fastening of the transmission elements (3) to the flanges is effected by axial clamping of two collar sleeves (10, 11) which are traversed by a screw (19) and which are engaged into aligned bores of the transmission elements and of the flanges. The collar of each sleeve bears against opposite faces of the transmission elements respectively of the flange. The two shafts (12, 13) of the collar sleeves are coupled to each other by locking while enabling an axial displacement with respect to each other and excluding a relative rotation of the sleeves. Thus, the loosening of the screw fastening is avoided.

Description

Schraubensicherung insbesondere für Wellenkupplungen Screw locking especially for shaft couplings
Die Erfindung betrifft eine Schraubensicherung insbesondere für Wellenkupplungen gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a screw lock especially for shaft couplings according to the preamble of patent claim 1.
Eine solche Schraubensicherung ist aus der DE-AS 26 45 600 bekannt, welche eine Wellenkupplung betrifft. Bei den dort beschriebenen Ausfuhrungsformen endet der Schaft der Bundhülse an der Seite des Kupplungsflansches, die den Übertragungsgliedern zugewandt ist. Am Bund der Hülse greift die eine glatte Auflagefläche aufweisende Mutter an. Gegen die andere Seite des Flansches stützt sich der Kopf der Durchsteckschraube mit seiner ebenfalls glatten Auflagefläche ab. Bei einer derart ausgebildeten Schraubverbindung ist deren Lockern aufgrund von Relativbewegungen zwischen der Bundhülse und dem Kupplungsflansch, welche die Auflageflächen für die Mutter und den Schraubenkopf bilden, nicht ausgeschlossen. Diese Relativbewegung zwischen Kupplungs¬flansch und Bundhülse beruht auf einem Moment um die Schraubenachse, dessen Entstehen in der DE-OS 27 25 289 beschrieben ist. Somit geht bei den gelösten Schraubverbindungen der durch den Reibschluß gegebene Anteil der Kraftübertragung zwischen der entsprechenden Kupplungshälfte und den Übertragungsgliedern verloren. Zwar findet bei Verlust der Vorspannkraft der Schraube die Drehmomentübertragung formschlüssig statt, da nach einer Relativbewegung der Kupplungsflansche die Fertigungstoleranzen ausgeglichen werden und somit der Schraubenschaft zur Anlage an den Flansch sowie an die Bundhülse und diese zur Anlage an die Übertragungselemente gebracht wird. Dennoch nimmt die Übertragungsfähigkeit der bekannten Wellenkupplung ab, weil bei formschlüssiger Einleitung der Kräfte in die Übertragungselemente die Gefahr des Ausfalls der Kupplung aufgrund erhöhter Kerbwirkung an den Schäften der Bundhülsen ansteigt. Dadurch nimmt die Spannung in den Übertragungselementen bei gleicher Drehmomentbelastung zu und führt evtl. zur Überlastung der Kupplung.Such screw locking is known from DE-AS 26 45 600, which relates to a shaft coupling. In the embodiments described there, the shaft of the collar sleeve ends on the side of the coupling flange which faces the transmission members. The nut, which has a smooth contact surface, engages the collar of the sleeve. The head of the push-through screw with its smooth bearing surface is supported against the other side of the flange. In the case of a screw connection designed in this way, its loosening is not ruled out due to relative movements between the collar sleeve and the coupling flange, which form the contact surfaces for the nut and the screw head. This relative movement between the coupling flange and the collar sleeve is based on a moment about the screw axis, the creation of which is described in DE-OS 27 25 289. Thus, the loosened screw connections go through the Given frictional share of the power transmission between the corresponding coupling half and the transmission members lost. If the pretensioning force of the screw is lost, the torque transmission takes place positively, since after a relative movement of the coupling flanges, the manufacturing tolerances are compensated and the screw shaft is brought into contact with the flange and the collar sleeve and this is brought into contact with the transmission elements. Nevertheless, the transmission capacity of the known shaft coupling decreases because, when the forces are positively introduced into the transmission elements, the risk of coupling failure increases due to an increased notch effect on the shafts of the collar sleeves. As a result, the tension in the transmission elements increases with the same torque load and may lead to overloading of the clutch.
Der Erfindung liegt die Aufgabe zugrunde, das Lösen der Schraubverbindungen insbesondere zwischen den Übertragungsgliedern und den entsprechenden Kupplungshälften sowie der an diesen festgespannten Bauteile von Wellenkupplungen mit einfachen Mitteln zu vermeiden.The invention has for its object to avoid the loosening of the screw connections in particular between the transmission members and the corresponding coupling halves and the components of shaft couplings clamped to them with simple means.
Diese Aufgabe wird durch die im Patentanspruch 1 gekennzeichneten Merkmale gelöst. Diese Lösung ist insofern vorteilhaft, als aufgrund des Formschlusses zwischen den miteinander verbundenen beiden Bundhülseπ keine relative Drehbewegung auftreten kann, welche ein Lösen der Schraubverbindung hervorrufen könnte. Dagegen wird die relative Axialbeweglichkeit der Bundhülsen gegeneinander ermöglicht, um die zur reibschlüssigen Verbindung der Übertragungsglieder mit dem Kupplungsflansch erforderliche Vorspannkraft der Verschraubung aufzubringen.This object is achieved by the features characterized in claim 1. This solution is advantageous in that, due to the positive connection between the two collar sleeves that are connected to one another, no relative rotary movement can occur, which could cause the screw connection to be loosened. In contrast, the relative axial mobility of the collar sleeves relative to one another is made possible in order to apply the prestressing force of the screw connection required for the frictional connection of the transmission members to the coupling flange.
Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen gekennzeichnet. Durch die im Patentanspruch 2 angegebene Maßnahme wird auf relativ einfache Weise ein kostengünstig herstellbarer, wirkungsvoller Formschluß zwischen den beiden Bundhülsen erzielt.Advantageous embodiments of the invention are characterized in the subclaims. Due to the measure specified in claim 2, an inexpensive to produce, effective positive locking between the two collar sleeves is achieved in a relatively simple manner.
Mittels der Maßnahme des Anspruchs 3 wird durch lediglich eine Schraube die Vorspannkraft der Schraubverbindung aufgebracht, wobei die Positionierung der Schraube durch das Gewinde der Bundhülse erfolgt. Bei dieser Ausgestaltung wird durch den Fortfall einer Mutter Einbauraum und Gewicht gespart.By means of the measure of claim 3, the prestressing force of the screw connection is applied by only one screw, the screw being positioned by the thread of the collar sleeve. In this embodiment, installation space and weight are saved by eliminating a mother.
Bei einer Schraubensicherung für Wellenkupplungen mit beiderseits an den Übertragungsgliedern im Bereich jeder Einspannung angeordneten Spannscheiben wird durch die im Anspruch 4 angegebene Ausgestaltung vermieden, daß sich der Stift aus seiner Bohrung herausarbeiten und eine Verdrehen der Spannscheiben erfolgen kann.In the case of a screw locking device for shaft couplings with tensioning disks arranged on both sides on the transmission members in the area of each clamping, the embodiment specified in claim 4 prevents the pin from working out of its bore and twisting of the tensioning disks can take place.
Die im Anspruch 5 erwähnte Maßnanme verfolgt den Zweck, mit einer bewährten Losdrehsicherung die Zuordnung der Schraube und der Mutter zu der jeweiligen Bundhülse zu erhalten.The measure mentioned in claim 5 pursues the purpose of obtaining the assignment of the screw and the nut to the respective collar sleeve with a proven anti-rotation lock.
Zwei Ausführungsbeispiele der Erfindung sind nachstehend anhand der Zeichnung näher erläutert. Es zeigen:Two embodiments of the invention are explained below with reference to the drawing. Show it:
Figur 1 im Halbschnittt eine Kupplungshälfte mit am Kupplungsflansch angreifenden Übertragungsgliedern, deren Befestigung durch zwei ineinandergreifende, von einer Schraube mit Mutter verspannte Bundhülsen erfolgt, als erstes Ausführungsbeispiel der Schraubensicherung undFigure 1 in half section a coupling half with transmission members acting on the coupling flange, the attachment of which is carried out by two interlocking collar sleeves clamped by a screw with nut, as the first embodiment of the screw locking and
Figur 2 ebenfalls im Halbschnitt eine entsprechend gestaltete Kupplungshälfte, bei der die Hülsen jedoch von lediglich einer Schraube verspannt sind, als zweites Ausführungsbeispiel der Schraubensicherung. Bei dem in Figur 1 dargestellten ersten Ausführungsbeispiel ist lediglich die eine Hälfte 1 von zwei zueinander achsgleich liegenden Kupplungshälften abgebildet. Derartige Kupplungen sind aus der eingangs erwähnten DE-AS 26 45 600 bekannt. Zwischen den gegenüberliegenden Hälften der Wellenkupplung ist rechtwinklig zur Drehachse 2 ein Paket' Ringscheiben 3 als Übertragungsglieder angeordnet. Diese Ringscheiben 3 sind abwechselnd an den beiden Kupplungshälften befestigt. Eine derartige Befestigung ist im nachfolgenden ausführlich beschrieben:Figure 2 also in half section a correspondingly designed coupling half, in which the sleeves are clamped by only one screw, however, as a second embodiment of the screw locking. In the first exemplary embodiment shown in FIG. 1, only one half 1 of two coupling halves lying axially with one another is shown. Such couplings are known from the aforementioned DE-AS 26 45 600. Between the opposite halves of the shaft coupling, a packet of washers 3 is arranged at right angles to the axis of rotation 2 as transmission elements. These washers 3 are alternately attached to the two coupling halves. Such attachment is described in detail below:
Im Bereich der Einspannung der Übertragungsglieder an der Kupplungshälfte 1 sind an beiden Seiten des Ringscheibenpakets 3 Spannscheiben 4 und 5 angeordnet. Eine drehfeste Verbindung der Spannscheiben 4 und 5 mit den Ringscheiben 3 ist durch einen in einer fluchtenden Bohrung 6 dieser Bauteile sitzenden Stift 7 erzielt. Das Ringscheibenpaket 3 stützt sich mit seiner Spannscheibe 4 gegen eine Stirnseite eines Flansches 8 der Kupplungshälfte 1 ab. Eine parallel zur Drehachse 2 verlaufende Bohrung 9 erstreckt sich fluchtend durch diesen Flansch 8 sowie durch die Spannscheiben 4 und 5 und das Ringscheibenpaket 3. In diese Durchgangsbohrung 9 greifen von beiden Seiten zwei Bundhülsen 10 und 11 mit ihrem Schaft 12 und 13 passend ein. Der Bund 14 der einen Bundhülse 10 stützt sich dabei gegen die flanschabgewandte Stirnseite der Spannscheibe 5 ab. Da der Bund 14 der Bundhülse 10 die Bohrung 6 in der Spannscheibe 5 teilweise überdeckt, wird der Stift 7 in seinem Sitz gehalten. Der Bund 15 der anderen Hülse 11 liegt dagegen auf der vom Ringscheibenpaket 3 abgewandten Seite des Kupplungsflansches 8 an.In the area of the clamping of the transmission members on the coupling half 1, 3 clamping disks 4 and 5 are arranged on both sides of the ring disk set. A rotationally fixed connection of the clamping washers 4 and 5 with the ring washers 3 is achieved by a pin 7 seated in an aligned bore 6 of these components. The washer package 3 is supported with its spring washer 4 against an end face of a flange 8 of the coupling half 1. A bore 9 running parallel to the axis of rotation 2 extends in alignment through this flange 8 as well as through the spring washers 4 and 5 and the washer assembly 3. Two collar sleeves 10 and 11 with their shafts 12 and 13 fit into this through bore 9 from both sides. The collar 14 of the one collar sleeve 10 is supported against the flange-facing end face of the spring washer 5. Since the collar 14 of the collar sleeve 10 partially covers the bore 6 in the clamping disk 5, the pin 7 is held in its seat. The collar 15 of the other sleeve 11, however, rests on the side of the coupling flange 8 facing away from the annular disk pack 3.
Die Schäfte 12 und 13 der beiden Bundhülsen 10 und 11 sind weitgehende spielfrei formschlüssig ineinandergreifend ausgebildet. Hierzu weist die Bundhülse 11 zwei Klauen 16 auf, denen zwei Gegenklauen 17 der anderen Bundhülse 10 zugeordnet sind. Auf diese Weise sind zwar die beiden Bundhülsen 10 und 11 axial gegeneinander verschiebbar, eine Drehbewegung der einen Hülse gegen die andere wird jedoch vermieden. Die beiden Bundhülsen 10 und 11 sind vom Schaft 18 einer Paßschraube 19 durchdrungen, deren Kopf 20 sich mit seiner Auflagefläche gegen den Bund 14 der ringscheibenseitigen Bundhülse 10 abstützt. Am Bund 15 der anderen Bundhülse 11 greift eine der Paßschraube 19 zugeordnete Mutter 21 mit ihrer Auflagefläche an. Bei einer von Zentrifugalkräften weniger hoch belasteten Wellenkupplung kann es ausreichend sein, anstelle der Paßschraube 19 eine handelsübliche Durchsteckschraube zu verwenden. In diesem Falle können an den Auflageflächen des Schraubenkopfs und der Mutter Sperrzähne oder Rippen als Schraubensicherung Verwendung finden.The shafts 12 and 13 of the two collar sleeves 10 and 11 are designed to be largely interlocking without play. For this purpose, the collar sleeve 11 has two claws 16, to which two mating claws 17 of the other collar sleeve 10 are assigned. In this way, the two collar sleeves 10 and 11 are axially displaceable relative to one another, but a rotational movement of the one sleeve against the other is avoided. The two collar sleeves 10 and 11 are penetrated by the shank 18 of a dowel screw 19, the head 20 of which is supported with its contact surface against the collar 14 of the collar sleeve 10 on the ring disk side. On the collar 15 of the other collar sleeve 11 a nut 21 assigned to the fitting screw 19 engages with its contact surface. In the case of a shaft coupling which is less heavily loaded by centrifugal forces, it may be sufficient to use a commercially available push-through screw instead of the fitting screw 19. In this case, locking teeth or ribs can be used as screw locking on the contact surfaces of the screw head and the nut.
Das in Figur 2 dargestellte zweite Ausführungsbeispiel unterscheidet sich vom ersten im wesentlichen dadurch, daß die Bundhülse 10' mit Innengewinde versehen ist, in das eine Schraube 19' mit ihrem Gewindeschaft 18' eingreift. Die Schraube 19' stützt sich mit ihrem Kopf 20' gegen den Bund 15' der anderen Bundhülse 11' ab und verspannt die beiden Bundhülsen 10' und 11', so daß eine reibschlüssige Verbindung des Ringscheibenpakets 3' sowie der beiderseits angeordneten Spannscheiben 4' und 5' am Flansch 8' der Kupplungshälfte 1' erzielt wird. Bei der Verwendung einer solchen Schraube 19' wird auf eine Passung zwischen ihrem Schaft 18' und den Bundhülsen 10' und 11' verzichtet, da die Positionierung der Schraube durch das Gewinde der Bundhülse 10' erfolgt. Als Losdrehsicherung ist die Schraube 19' an der Auflagefläche ihres Kopfes 20' mit Sperrzähnen 22' versehen, die an der flanschabgewandten Seite des Hülsenbundes 15' angreifen. The second exemplary embodiment shown in FIG. 2 differs from the first one essentially in that the collar sleeve 10 'is provided with an internal thread into which a screw 19' engages with its threaded shaft 18 '. The screw 19 'is supported with its head 20' against the collar 15 'of the other collar sleeve 11' and braces the two collar sleeves 10 'and 11', so that a frictional connection of the ring washer pack 3 'and the clamping disks 4' and 5 'on the flange 8' of the coupling half 1 'is achieved. When using such a screw 19 ', there is no fit between its shaft 18' and the collar sleeves 10 'and 11', since the screw is positioned by the thread of the collar sleeve 10 '. To prevent rotation, the screw 19 'is provided on the bearing surface of its head 20' with locking teeth 22 'which engage on the side of the sleeve collar 15' facing away from the flange.
