Description

HILFSMITTEL ZUR BEFESTIGUNG VON GEWINDEBAUTEILEN AID FOR ATTACHING THREADED COMPONENTS
Die Erfindung befasst sich mit dem Problem, ein Bauteil, das ein Außengewinde auf weist, einfach und sicher in einer Bohrung zu befestigen, die kein passendes Innenge- winde hat. The invention deals with the problem of simply and securely fastening a component that has an external thread in a bore that does not have a matching internal thread.
Die übliche Lösung dieses Problems besteht darin, dass mit einem Gewindeschneider ein Innengewinde in die Wand der Bohrung eingeschnitten wird. Es sind auch Gewindebauteile, beispielsweise Schmiernippel bekannt, die ein soge nannte Selbstformgewinde haben. Darunter versteht man ein Außengewinde, das in Ein schraubrichtung konisch verjüngt ist und das aus einem so hartem Material besteht, dass es selbstformend in eine Bohrung eingedreht werden kann. Da jedoch zum Eindrehen eines solchen Selbstformgewindes in die Bohrung ein relativ hohes Drehmoment benö- tigt wird, andererseits jedoch die Schmiernippel mit Selbstformgewinde nur einen rela tiv flachen Sechskant als Drehhandhabe aufweisen, kommt es vor, dass das über den Sechskant übertragbare Drehmoment nicht ausreicht, das Selbstformgewinde vollstän dig in die Bohrung einzuschrauben. Aufgrund der konischen Form des Gewindes kann dann der Schmiernippel relativ leicht wieder aus der Bohrung herausgerissen werden. Dabei wird das Innengewinde der Bohrung zumeist so stark beschädigt, dass auch ein neuer Schmiernippel in dieser Bohrung keinen ausreichenden Halt mehr hat. The usual solution to this problem is to use a tap to cut an internal thread in the wall of the hole. There are also threaded components, such as grease nipples known that have a so-called self-tapping thread. This is an external thread that tapers conically in the screwing direction and is made of such a hard material that it can be screwed into a bore hole in a self-tapping manner. However, since a relatively high torque is required to screw such a self-tapping thread into the bore, and on the other hand the lubricating nipples with self-tapping threads only have a relatively flat hexagon as a turning handle, it can happen that the torque that can be transmitted via the hexagon is not sufficient, that Screw the self-tapping thread fully into the bore. Due to the conical shape of the thread, the lubricating nipple can then be torn out of the bore relatively easily. The internal thread of the bore is usually so severely damaged that even a new grease nipple no longer has sufficient support in this bore.
Aufgabe der Erfindung ist es, eine alternative Möglichkeit zur Befestigung von Schmiernippeln und anderen Gewindebauteilen zu schaffen. The object of the invention is to provide an alternative way of attaching grease nipples and other threaded components.
Diese Aufgabe wird erfindungsgemäß gelöst durch ein Hilfsmittel in der Form einer Schraube mit Selbstformgewinde und einem Kopf, der an seinem Außenumfang eine Werkzeughandhabe bildet, wobei das Hilfsmittel dadurch gekennzeichnet ist, dass der Kopf eine axiale Innengewindebohrung aufweist. This object is achieved according to the invention by an aid in the form of a screw with a self-tapping thread and a head that forms a tool handle on its outer circumference, the aid being characterized in that the head has an axial internally threaded bore.
Die Innengewindebohrung passt zu dem Außengewinde des zu befestigenden Bauteils. Somit ist es möglich, zunächst die Schraube mit ihrem Selbstformgewinde in die Boh rung einzudrehen und fest anzuziehen, so dass ein sicherer Halt der Schraube in der Bohrung gewährleistet ist, und dann das zu befestigende Bauteil, beispielsweise den Schmiernippel, in der Innengewindebohrung im Kopf der Schraube zu befestigen. The internal thread hole matches the external thread of the component to be fastened. This makes it possible to first screw the screw with its self-tapping thread into the hole and tighten it firmly so that the screw is held securely in the hole, and then insert the component to be fastened, such as the grease nipple, into the internally threaded hole in the head of the screw to fasten.
Vorteilhafte Ausgestaltungen sind in den Unteransprüchen angegeben. Advantageous configurations are specified in the dependent claims.
In einer Ausführungsform hat der die Werkzeughandhabe, beispielsweise in der Form von Schlüsselflächen, bildende Kopf der Schraube, vorzugsweise ein Sechskantkopf, eine Höhe, die mindestens 60% des größten Durchmessers des Selbstformgewindes be trägt. Vorzugsweise ist die Höhe des Kopfes größer als der größte Durchmesser des Selbstformgewindes. Dadurch ist es möglich, mit einem geeigneten Schraub Werkzeug, beispielsweise einer Knarre, ein sehr hohes Drehmoment zu übertragen, so dass sicher gestellt werden kann, dass das Selbstformgewinde auch in sehr harten Materialien tief genug eingeschraubt wird. So lässt sich das Hilfsmittel auch dazu einsetzen, eine ausgerissene Gewindebohrung so zu erneuern, dass wieder ein intaktes, zu dem Außengewinde des zu befestigenden Bau teils passendes Innengewinde geschaffen wird. In one embodiment, the head of the screw, preferably a hexagonal head, forming the tool handle, for example in the form of wrench flats, has a height which is at least 60% of the largest diameter of the self-tapping thread. Preferably, the height of the head is greater than the largest diameter of the self-tapping thread. This makes it possible to transmit a very high torque with a suitable screwing tool, for example a ratchet, so that it can be ensured that the self-tapping thread is screwed in deep enough even in very hard materials. The tool can also be used to replace a torn-out threaded hole in such a way that an intact internal thread that matches the external thread of the component to be fastened is created again.
Das Selbstformgewinde und das Innengewinde der Schraube können zueinander kom plementär sein in dem Sinne, dass beide Gewinde den gleichen Durchmesser, die glei che Ganghöhe und die gleiche Steigung aufweisen, wobei jedoch das Innengewinde nicht die konische Verjüngung des Selbstformgewindes aufzuweisen braucht. In dem Fall ist es beispielsweise auch möglich, das erfindungsgemäße Hilfsmittel als eine Art Gewindefomer einzusetzen, mit dem in der Bohrung ein Gewinde geschaffen wird, in das dann ein Bauteil mit dem gleichen Selbstformgewinde, beispielsweise ein Schmiernippel, eingeschraubt werden kann. The self-tapping thread and the internal thread of the screw may be complementary to each other in the sense that both threads have the same diameter, pitch and pitch, but the internal thread need not have the taper of the self-tapping thread. In this case it is also possible, for example, to use the aid according to the invention as a type of thread former, with which a thread is created in the bore, into which a component with the same self-tapping thread, for example a grease nipple, can then be screwed.
Es sind jedoch auch Ausführungsformen denkbar, bei denen sich das Selbstformge winde und das Innengewinde in der Gewindenorm unterscheiden. Dabei kann gegebe nenfalls der Gewindeabschnitt, der das Selbstformgewinde bildet, eine größere Wanddi cke haben als der Selbstform-Gewindeabschnitt eines üblichen Schmiernippels, so dass eine größere mechanische Stabilität erreicht wird. However, embodiments are also conceivable in which the self-forming thread and the internal thread differ in the thread standard. In this case, the thread section that forms the self-forming thread can optionally have a greater wall thickness than the self-forming thread section of a conventional grease nipple, so that greater mechanical stability is achieved.
Je nach Ausgestaltung des Innengewindes kann das erfindungsgemäße Hilfsmittel auch dazu genutzt werden, Gewindeteile miteinander zu verbinden, die nicht-kompatible Ge windenormen haben. Beispielsweise kann ein erfindungsgemäßes Hilfsmittel mit metri schem Innengwinde dank seines Selbstformgewindes auch in eine Bohrung mit einem Zoll-Gewinde eingeschraubt werden, so dass sich dann ein Bauteil mit metrischem Au ßengewinde in einer Bohrung mit Zoll-Innengewinde befestigen lässt. Entsprechend kann auch ein Bauteil mit Zoll-Außengewinde in einer Bohrung mit metrischem Innen gewinde befestigt werden. Depending on the design of the internal thread, the tool according to the invention can also be used to connect threaded parts that have non-compatible Ge thread standards. For example, thanks to its self-tapping thread, an aid according to the invention with a metric internal thread can also be screwed into a hole with an inch thread, so that a component with a metric external thread can then be fastened in a hole with an inch internal thread. Accordingly, a component with an inch external thread can also be fastened in a hole with a metric internal thread.
Im Folgenden wird ein Ausführungsbeispiel anhand der Zeichnung näher erläutert. Es zeigen: An exemplary embodiment is explained in more detail below with reference to the drawing. Show it:

Fig. 1 und 2 zeigen ein Befestigungshilfsmittel in der Form einer Schraube 10 mit ei nem Selbstformgewinde 12 und einem Kopf 14. Der Kopf 14 ist ein Sechskantkopf und bildet somit an seinem äußeren Umfang sechs Schlüsselflächen 16. Außerdem weist der Kopf 14 eine axiale Innengewindebohrung 18 auf, die über einen konischen Bohrungs- abschnitt 20 in eine glatte axiale Bohrung 22 in dem Gewindeabschnitt übergeht, der das Selbstformgewinde 18 bildet. 1 and 2 show a fastening aid in the form of a screw 10 with a self-tapping thread 12 and a head 14. The head 14 is a hexagonal head and thus forms six wrench flats 16 on its outer circumference. The head 14 also has an axial internally threaded bore 18 , which transitions via a conical bore section 20 into a smooth axial bore 22 in the threaded section that forms the self-tapping thread 18 .
Die Höhe des Kopfes 14 und damit auch die Höhe der Schlüsselflächen 16 ist größer als der maximale Durchmesser des Selbstformgewindes 12. Die Innengewindebohrung 18 hat im gezeigten Beispiel ein metrisches Gewinde mit dem gleichen Durchmesser, der gleichen Ganghöhe und der gleichen Steigung wie das Selbstformgewinde 12. The height of the head 14 and thus also the height of the wrench flats 16 is greater than the maximum diameter of the self-tapping thread 12. The internally threaded bore 18 has in the example shown a metric thread with the same diameter, the same pitch and the same pitch as the self-tapping thread 12.
Fig. 3 zeigt die Schraube 10 in einem Zustand, in dem sie mit dem Ende ihres Selbst- formgewindes an die Öffnung einer Bohrung 24 in einem Basisbauteil 26 angesetzt ist. In Fig. 4 ist die Schraube 10 mit einem Hammer leicht in die Bohrung 24 eingeschlagen worden, so dass sie nicht von Hand in Position gehalten zu werden braucht. Die Schraube wird dann mit einem Schraubenschlüssel oder einer Knagge tiefer in die Boh rung 24 eingeschraubt, wobei sich das Selbstformgewinde 12 in die Wand der Bohrung einschneidet und dort ein Innengewinde schafft. FIG. 3 shows the screw 10 in a state in which the end of its self-tapping thread is attached to the opening of a bore 24 in a base component 26 . In Figure 4, the screw 10 has been lightly tapped into the bore 24 with a hammer so that it does not need to be held in position by hand. The screw is then screwed deeper into the bore 24 with a wrench or cleat, with the self-tapping thread 12 cutting into the wall of the bore and creating an internal thread there.
Fig. 5 zeigt die Schraube 10 im vollständig eingeschraubten Zustand. Außerdem ist in die Innengewindebohrung 18 ein Schmiernippel 28 eingeschraubt worden, der seiner seits einen flachen Sechskantkopf 30 und ein Selbstformgewinde 32 aufweist, das mit dem Selbstformgewinde der Schraube 10 formidentisch ist. 5 shows the screw 10 in the fully screwed-in state. In addition, a grease nipple 28 has been screwed into the internally threaded bore 18, which in turn has a flat hexagonal head 30 and a self-tapping thread 32, which is identical in shape to the self-tapping thread of the screw 10.
Fig. 6 zeigt die Bohrung 24 des Basisbauteils 26 mit einem konischen Innengewinde 34, das durch das Selbstformgewinde 12 in die Umfangswand der Bohrung eingeschnitten wurde und es nach Entfernen der Schraube 10 erlaubt, den Schmiernippel 28 auch direkt in die Bohrung 24 einzuschrauben, wie in Fig. 7 gezeigt ist. Fig. 6 shows the bore 24 of the base component 26 with a conical internal thread 34, which was cut into the peripheral wall of the bore by the self-tapping thread 12 and, after removing the screw 10, also allows the grease nipple 28 to be screwed directly into the bore 24, as in 7 is shown.
