Description
Fitting mit Innengewinde. Vorliegende Erfindung hat zum Gegen stand einen neuartigen Fitting mit Innenge winde.
In der beiliegenden Zeichnung zeigt Fig. 1 ein Bruchstück einer bisher ge bräuchlichen Ausführungsform des Innenge windes mit Abfasung eines Fittings im Längs schnitt.
In Fig. 2 und 3 ist der Erfindungsgegen stand beispielsweise veranschaulicht, und zwar zeigt Fig. 2 ein Bruchstück des Innengewindes mit Abfasung eines Fittings im Längsschnitt wie er den Gegenstand vorliegender Erfindung bildet, Fig. 3 einen Fitting gemäss Erfindung in Draufsicht.
Bei der bisherigen Ausführungsform des Innengewindes 1 wurde dasselbe am äussern Ende mit einer Abfasung 2 versehen, deren Erzeugende eine gerade Linie bildet. Im Ge gensatz zu dieser Ausführungsform verläuft die Abfasung 3 bei der Ausführungsform ge- mäss vorliegender Erfindung (Fig. 2) beim Übergang in das Innengewinde 4 nach einer Kurve. Diese Anordnung bezweckt, die Win kel, welche die Abfasung mit den Gewinde flanken bildet, zu vergrössern. Gleichzeitig wird durch diese Anordnung eine Gratbildung beim Übergang der Abfasung in das Innen gewinde vermieden.
Die Abfasung kann auf ihrer ganzen Länge nach einer Kurve verlaufen oder es kann die äussere Partie derselben eine Gerade als Erzeugende aufweisen.
Fitting with internal thread. The present invention relates to a novel fitting with Innenge threads.
In the accompanying drawings, Fig. 1 shows a fragment of a previously ge customary embodiment of the Innenge thread with chamfering of a fitting in the longitudinal section.
In Fig. 2 and 3 the subject matter of the invention is illustrated for example, namely Fig. 2 shows a fragment of the internal thread with chamfering of a fitting in longitudinal section as it forms the subject of the present invention, Fig. 3 shows a fitting according to the invention in plan view.
In the previous embodiment of the internal thread 1, the same was provided at the outer end with a chamfer 2, the generatrix of which forms a straight line. In contrast to this embodiment, the bevel 3 in the embodiment according to the present invention (FIG. 2) runs after a curve at the transition into the internal thread 4. The purpose of this arrangement is to enlarge the angle that forms the chamfer with the thread. At the same time, this arrangement avoids the formation of burrs at the transition from the chamfer to the internal thread.
The chamfer can run along a curve over its entire length or the outer part of the same can have a straight line as the generatrix.
