Abstract

The milling cutter is designed for manufacturing large gear wheels and consists of several discs (1, 2, 3) having parallel faces and provided with toothed helicoidal crowns. The latter include interchangeable, reversible hard metal plates (10, 11) serving as lateral edges and spaced radially and alternately in order of teeth cutting to the right and left so that the edges are superposed. The metal plates are positioned on edge, i.e. with their narrow faces forming the surface of a cutting tool. The tooth which cuts perpendicularly to the axis of the cutter has, at its tip, a hard metal plate with a circular edge in order to produce a rounded bottom in the cut.

Description

Mehrteiliger Abwälzfräser Multi-part hob

Zusatz nach Patent ... (P 27 00 525.0) Gegenstand des Hauptpatentes... (P 27 00 525.0) ist ein Abwälzfräser zur Herstellung von Verzahnungen, insbesondere von Verzahnungen bis etwa Modul 40, bestehend aus mehreren und mit planparallelen Stirnflächen\mit der der Fräsersteigung entsprechenden schraubenförmigen Zahnkränzen versehenen Scheiben, deren Zahnkränze mit kreuzverzahnt angeordneten, auswechselbaren Hartmetallmessern bestückt sind, wobei die Harmetallbestückung ihrerseits aus Hartmetall-Wendeplatten als Kopf- und Seitenschneider besteht, die in der Aufeinanderfolge der Zähne rechts- und linksschneidend mit wechselndem radialem Abstand angeordnet sind derart, daß die seitenschneidenden Wendeplatten beim Fräserumlauf einander überdecken. Addition according to patent ... (P 27 00 525.0) Subject matter of the main patent ... (P 27 00 525.0) is a hobbing cutter for the production of gears, in particular from gears up to about module 40, consisting of several and with plane-parallel End faces \ with the helical gear rims corresponding to the milling cutter pitch provided disks, the sprockets with interchangeable arranged cross-cut Tungsten carbide knives are equipped, with the Harmetal tipping in turn from tungsten carbide inserts as head and side cutter, which in the succession of the teeth right and left-hand cutting are arranged with alternating radial spacing such that the side-cutting indexable inserts overlap each other as the cutter rotates.

Das Hauptpatent sieht vor, daß der Abwälzfräser aus mehreren mit schraubenförmigen Zahnkränzen versehenen Scheiben besteht, und zwar nach dem Ausführungsbeispiel aus drei solcher Scheiben. Es wurde erkannt, daß bei kleinmoduligen Verzahnungen weniger als drei mit Zahnkränzen versehene schraubenförmige Scheiben ausreichend sind, nämlich nur eine oder zwe. solcher Scheiben.The main patent provides that the hob from several with helical There are disks provided with sprockets, according to the exemplary embodiment three such discs. It was recognized that with small-module gears less than three helical disks provided with gear rings are sufficient, viz just one or two. such discs.
