Description

Durch einen verschleißfesten Umguß geschützte Schraubenmutter Die Erfindung betrifft eine zum Anschrauben der Verschleißbekleidung nach Patentanmeldung G 10349 IVc/80a dienende Schraubenmutter mit verschleißfestem Umguß. Die Schraubenmutter ist eine Steckschlüsselmutter mit einer durch den verschleißfesten Umguß nicht überdeckten Einstecköffnung für den Mutterschlüssel, bei welcher der verschleißfeste Umguß durch den Mutterschlüssel nicht beansprucht wird. Um auch an der Auflagestelle der Mutter eine Beanspruchung des spröden Umgusses zu vermeiden, steht nach vorliegender Zusatzerfindung der Umguß von der Auflagestelle der Mutter etwas zurück.Screw nut Die protected by a wear-resistant casting The invention relates to one for screwing on the wear clothing according to patent application G 10349 IVc / 80a serving screw nut with wear-resistant encapsulation. The nut is a socket wrench nut with one that is not covered by the wear-resistant encapsulation Insertion opening for the nut wrench, in which the wear-resistant casting through the wrench is not used. To also at the support point of the mother According to the present additional invention, avoiding stress on the brittle encapsulation is required the casting back slightly from the mother's support point.

Es wurde schon vorgeschlagen, die Köpfe von Befestigungsschrauben mit einem Schutzüberzug zu versehen, welcher sie gegen chemische Angriffe schützt. Bei besonders harten und spröden Überzügen, wie sie bei der Schraubenmutter der Erfindung verwendet werden, besteht die Gefahr, daß der verschleißfeste Umguß an der Druckstelle der Mutter abplatzt. Diese Gefahr ist durch das Zurückstehen des harten Umgusses von der Auflagefläche der Mutter beseitigt.It has already been suggested that the heads of fastening screws to be provided with a protective coating, which protects them against chemical attacks. In the case of particularly hard and brittle coatings, as is the case with the nut of the Invention are used, there is a risk that the wear-resistant encapsulation the pressure point of the mother flakes off. This danger is due to the reluctance of the hard casting removed from the bearing surface of the nut.

In der Zeichnung ist in den Abb. 1. und 2 die Steckschlüsselmutter finit Umguß, in den Abb. 3 und 4 eine mit ihr angeschraubte Verschleißbekleidung dargestellt.In the drawing, the socket wrench nut is in Figs. 1 and 2 finite casting, in Figs. 3 and 4 wear clothing screwed on with it shown.

Die in Abb. 3 und 4 dargestellte Verschleißbekleidung ist durch ihre Schrauben 1 und die Muttern 2 an dem zu schützenden Maschinenteil 3 befestigt. Die Muttern 2 sind Steckschlüsselmuttern (Abb. 1 und 2) und haben einen verschleißfesten Umguß 4, der gegenüber der Auflagefläche 5 der Mutter 2 etwas zurücksteht, damit er beim Festspannen der Mutter nicht beansprucht wird.The wear clothing shown in Fig. 3 and 4 is by their Screws 1 and nuts 2 attached to the machine part 3 to be protected. the Nuts 2 are socket wrench nuts (Fig. 1 and 2) and have a wear-resistant one Umguß 4, which is slightly set back with respect to the support surface 5 of the nut 2, so it is not used when tightening the nut.
