Abstract

A roller milling tool is used for the production of toothing, and comprises several face surfaces which are parallel and discs with screw-form tooth crowns corresponding to the milling tool pitch. These tooth crowns have cross-toothed, exchangeable hard metal blades which are turn-plates acting as head and side cutters. The plates are rectangular. The teeth sequence on the blades are arranged to cut to the right and to the left with alternating radial clearance in such a way that the side-cutting turn plate edges overlap during the milling process.

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 Stirnflächenxmdt der der Fräsersteigung entsprechenden schraubenförmigen Zahnkränzen versehenen Scheiben, deren Zahnkränze mit kreuzverzahnt angeordneten, auswechselbaren Hartmetallmessern bestückt sind, wobei die Hartmetallbestückung ihrerseits aus Hartmetall-Wendeplatten als Dpf- 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 Front surface xmdt of the helical gear rims corresponding to the milling cutter pitch provided disks, the sprockets with interchangeable arranged cross-cut Tungsten carbide knives are equipped, the carbide tipping in turn from carbide inserts as a dpf 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.

Nach dem Hauptpatent... sollen die Hartmetall-Wendeplatten Quadratform haben. Dies hat den Vorteil, daß die Wendeplatten vor dem Wenden viermal um je 900 gedreht werden können, wenn eine Schneidkante stumpf geworden ist. Einschließlich der Wendemöglichkeit sind bei quadratischen Hartmetall-Wendeplatten also acht Schneidkanten zum Einsatz zu bringen.According to the main patent ... the carbide indexable inserts should be square to have. This has the advantage that before turning the inserts four times by 900 can be rotated when a cutting edge has become blunt. Including the turning option for square carbide indexable inserts is therefore eight cutting edges to bring to use.

Die Quadratform der Hartmetall-Wendeplatten bringt es jedoch mit sich, daß bei großmoduligen Verzahnungen eine größere Anzahl von seiten schneidenden Wendeplatten vorgesehen werden müssen, um das Erfordernis der Uberdeckung beim Fraserumlauf zu erfüllen. Um aus Herstellungsgründen die erforderliche Anzahl von Hartmetall-Wendeplatten zu vermindern, sieht die Erfindung die Verwendung von Hartmetall-Wendeplatten in Rechteckform vor.However, the square shape of the carbide indexable inserts means that with large-module gears a larger number of side-cutting indexable inserts must be provided in order to meet the requirement of overlap during milling fulfill. In order to obtain the required number of carbide indexable inserts for manufacturing reasons to reduce, the invention provides the use of hard metal indexable inserts in Rectangular shape before.
