Description

Bei Leiterzahnstangen hat man früher die Zähne direkt in die Wangen eingenietet oder angeschraubt, wobei man das Kanten der Zähne teilweise durch flächige Formgebung der Befestigungszapfen oder durch Auf- oder Einlegen besonderer Konstruktionsteile verhindern wollte. Es sind auch Ausführungen bekannt, bei denen der Zahn an Leisten oder Rippen der Wangeneisen zur Anlage kommt, um das Kanten zu vermeiden. Alle diese Ausführungen verlangten Anpaßarbeiten. Trotzdem lockerten sich die Zähne nach längerer-Betriebsdauer oder bei höheren Zahndrücken.With ladder racks you used to have the teeth directly in the cheeks riveted or screwed on, whereby the edges of the teeth are partially by flat Shaping of the fastening pins or by placing or inserting special construction parts wanted to prevent. There are also known designs in which the tooth on ridges or ribs of the cheek iron comes to rest in order to avoid edging. All these Executions required adaptation work. Nevertheless, the teeth loosened after a long period of operation or with higher tooth pressures.

Die Zahnstange gemäß der Erfindung vermeidet diese Nachteile und vermeidet Einschaltung besonderer Konstruktionsteile zur Sicherung der Zähne gegen Kanten in den Wangen.The rack according to the invention avoids and avoids these disadvantages Use of special construction parts to secure the teeth against edges in the cheeks.

In den Abb. i, 2 und 3 ist die Befestigung eines Zahnes gemäß der Erfindung in einer Wang: dargestellt, wobei Abb. i den Querschnitt durch das Wangeneisen, Abb. 2 den Querschnitt durch einen Zahn und Abb. 3 den Grundriß von einem Zahn mit Wangenstück zeigt; Abb. 4 stellt den Querschnitt durch die Zahnstange an einem Zahn, Abb. 5 den Seitenriß und Längsschnitt und Abb. 6 den Grundriß eines Zahnstangenabschnittes mit mehreren Zähnen dar.In Figs. I, 2 and 3 the attachment of a tooth according to the Invention in a cheek piece: shown, with Fig. I the cross section through the cheek iron, Fig. 2 shows the cross section through a tooth and Fig. 3 shows the plan view of a tooth Cheek piece shows; Fig. 4 shows the cross section through the rack on a tooth, Fig. 5 is a side elevation and longitudinal section and Fig. 6 is a plan view of a rack section with several teeth.

In den rechteckigen Wangen i sind Einfräsungen 2 vorgesehen. Die Zähne 3 sind am Ende zu einem rechteckigen Querschnitt abgefräst und werden in die Wangen eingeschoben. Durch Schweißnähte 4 und 5 werden sie in den Wangen gehalten. Sie sind also gegen Verdrehen durch ihre seitlichen Flächen und die Schweißnähte, gegen Verschiebungen durch die Schweißnähte gehalten.Milled recesses 2 are provided in the rectangular cheeks i. The teeth 3 are milled off at the end to a rectangular cross-section and are inserted into the cheeks inserted. They are held in the cheeks by welds 4 and 5. she are therefore against twisting through their lateral surfaces and the weld seams Displacements held by the welds.

Die Vorteile der Anordnungen sind: Vermeidung besonderer Konstruktionsteile zur Sicherung gegen Kanten; unbedingte Sicherheit gegen Lockern oder Kanten durch die großen seitlichen Auflageflächen, geringste Länge der Schweißnähte und damit geringstes Verziehen der Wangen, keinerlei Anpaßarbeit, leichte Herstellung im Großserienbau durch geeignete Maschinen.The advantages of the arrangements are: Avoidance of special construction parts to protect against edges; absolute security against loosening or edges the large lateral contact surfaces, the smallest length of the weld seams and thus Minimal distortion of the cheeks, no adjustment work, easy production in large series using suitable machines.
