Description
Die Herstellung von' Zahnrädern erfolgt zur Zeit durch spanabhebende Bearbeitung. Im allgemeinen werden die Zahnlücken aus den Rohlingen herausgefräst. Das Verfahren hat den Nachteil, daß die Arbeit zeitraubend ist und hochwertige Sonderwerkzeugmaschinen und -werkzeuge erfordert. Ziel der Erfindung ist es daher, eine Vereinfachung und Verbilligung zu ermöglichen.The production of 'gears is currently done by machining Editing. In general, the tooth gaps are milled out of the blanks. The method has the disadvantage that the work is time consuming and high quality special machine tools and tools required. The aim of the invention is therefore to simplify and To enable cheaper.
Gegenstand der Erfindung ist zu diesem Zweck ein Verfahren zur Herstellung von Zahnrädern, bei denen eins oder mehrere aus Blech spanlos hergestellte, z: B. gestanzte Radscheiben durch Schweißen, Löten, Nieten o. dgl. mit der Nabe und den ebenfalls spanlos aus Blech 'hergestellten Zahnkranzlamellen verbunden werden. Dabei kann die Schweiß- oder Lötwärme gleichzeitig zum Härten der Radscheiben und Zahnktänze ausgenutzt werden.For this purpose, the invention relates to a method of production of gears in which one or more of the sheet metal is made without cutting, e.g. punched wheel disks by welding, soldering, riveting or the like with the hub and the gear ring lamellae are also connected without cutting from sheet metal. Included can use the welding or soldering heat at the same time to harden the wheel disks and tooth dances be exploited.
Ein Ausführungsbeispiel eines nach der Erfindung hergestellten Zahnrades ist durch die Zeichnung dargestellt. Sie zeigt eine abgebrochene Hälfte des Rades in Ansicht und Schnitt. Eine oder mehrere Radscheiben a werden auf üblichen Pressen unter Verwendung der erforderlichen Stanzwerkzeuge spanlos hergestellt. Zur Erhöhung ihrer Festigkeit können sie geprägte Rippen g erhalten, und zwecks Gewichtsersparnis können Ausschnitte f beliebiger Form mit ausgestanzt werden. Der Zahnkranz wird aus ebenfalls gestanzten Lamellen b gebildet. Die Nahe c besteht aus einem geprägten, gegossenen oder geschmiedeten Teil, der, soweit erforderlich, bearbeitet ist; sie hat einen Bund d, gegen den sich die Radscheiben d anlegen, und eine sehnenförmige: Abflachung e des Umfanges, der gleiche Abflachungen der Radscheiben entsprechen, so daß ein gegenseitiges Verdrehen verhindert wird. Die Verbindung der Radscheiben. a mit den Zahnkranzlamellen b und mit der Nabe c kann durch Schweißen; Hartlöten mit oder ohne Schutzgas, Weichlöten, Nieten o. dgl. erfolgen. Die Radscheiben und die Zahnkranzlamellen können wahlweise aus härtbarem oder @ im Einsatz härtbarem Werkstoff hergestellt sein. Die Härtung kann, wie oben erwähnt, unter Ausnutzung der Schweiß- oder Lötwärme erfolgen.An embodiment of a gear manufactured according to the invention is shown by the drawing. It shows a broken half of the wheel in view and section. One or more wheel disks a are made on conventional presses manufactured without cutting using the required punching tools. To increase For their strength they can be given embossed ribs g, and in order to save weight Cutouts of any shape can also be punched out. The ring gear will formed from also punched lamellae b. The near c consists of an embossed, cast or forged part, machined where necessary; she has a collar d, against which the wheel disks d rest, and a chord-shaped one: Flattening e of the circumference, which corresponds to the same flattening of the wheel disks, so that mutual twisting is prevented. The connection of the wheel disks. a with the ring gear lamellae b and with the hub c can be welded; Brazing with or without protective gas, soft soldering, rivets or the like. The wheel disks and the ring gear lamellae can be made of hardenable or @ in use hardenable Material be made. The hardening can, as mentioned above, take advantage of the welding or soldering heat.
