Kleindampfturbine mit angebautem Stromerzeuger.Small steam turbine with attached power generator.

Patentiert im Deutschen Reiche vom ,3, Juni 1925 ab.Patented in the German Empire on June 3, 1925.

Die vorliegende Erfindung bezweckt, eine möglichst zweckmäßige und gedrängte Bauart für Kleindampftu'iibiuen mit angebautem 'Stromerzeuger zu schaffen, die insbesondere zur Lichterzeugung auf Lokomotiven oder ähnlichen Fahrzeugen bestimmt sind, bei denen der Platz sowie das zulässige Gewicht beschränkt sind. Die Turbine ist dabei, um eine einfache und billige Anordnung zu erzielen, meistens nur mit einem Laufrad ausgerüstet, das fliegend angeordnet ist. Die Turbinenwelle muß aus Stahl hergestellt werden, um einen geringen Durchmesser für die Welle verwenden und die mittlere Durchbohrung des Laufrades möglichst klein halten zu können und um zu erreichen, daß auch bei geringem Durchmesser der Turbinenwelle die kritische Drehzahl unter der normalen Drehzahl der Turbine liegt. Die Stromerzeugerwelle anderseits besteht zweckmäßig aus Bronze oder aus einem anderen unmagnetischen Metall, um die Wirbelströme, die zu schädlichen Erwärmungen Anlaß geben, zu vermeiden. Bisher wurde nun für Turbine und Stromerzeuger eine Welle verwendet, die durchgellend aus Stahl hergestellt war, wobei zwischen dem Anker des Stromerzeugers und Stahl welle eine Büchse aus Bronze eingeschoben wurde. Dadurch wurden die Wirbelströme zwar gemildert, aber nicht beseitigt.,. .Außerdem mußten die Durchmesser des''Ankers, der Feldmagnete und des Gehäuses ijm die Dicke der Bronzebüchse vergrößert werden; dadurch wurden, besonders bei dicken Bronzebüchsen, die Beanspruchungen des Ankers 35 <■ nebst Wicklungen'. durch die Fliehkraft, die bei der hohen -Drehzahl der Turbine an und für sich ziemlich beträchtlich sind, noch in unerwünschter Weise erhöht.The aim of the present invention is to create the most expedient and compact design possible for small steam tubes with built-on power generators, which are intended in particular for generating light on locomotives or similar vehicles in which space and the permissible weight are limited. In order to achieve a simple and cheap arrangement, the turbine is mostly only equipped with one impeller which is arranged overhung. The turbine shaft must be made of steel in order to use a small diameter for the shaft and to be able to keep the central bore of the impeller as small as possible and to ensure that the critical speed is below the normal speed of the turbine even with a small diameter of the turbine shaft. The power generator shaft, on the other hand, is expediently made of bronze or some other non-magnetic metal in order to avoid the eddy currents which give rise to harmful heating. So far, a shaft was used for turbine and power generator, which was made of steel durchgellend, with a sleeve made of bronze was inserted between the armature of the power generator and steel shaft. As a result, the eddy currents were alleviated, but not eliminated.,. In addition, the diameter of the armature, the field magnets and the housing had to be increased in the thickness of the bronze sleeve; characterized the strains of the armature 35 <■ together with windings have been, particularly in thick Bronze bushings'. by the centrifugal force, which in and of itself are quite considerable at the high speed of the turbine, is still undesirably increased.

Diese Nachteile werden nach der ErfLn-These disadvantages will be

dung dadurch vermieden, daß die Welle aus zwei Teilen besteht, wobei die Welle der Turbine aus Stahl, die Welle des Stromerzeugers dagegen aus Bronze oder aus irgendeinem anderen unmagnetischen Baustoff hergestellt ist und wobei die beiden Wellen durch eine feste Kupplung miteinander verbunden sind.tion avoided in that the shaft consists of two parts, the shaft of the turbine made of steel, while the shaft of the generator is made of bronze or some other non-magnetic building material is made and the two shafts through a solid Coupling are interconnected.

Die Erfindung ist in der Zeichnung und in der folgenden Beschreibung näher erläutert.The invention is explained in more detail in the drawing and in the following description.

Die Zeichnung stellt einen Längsschnitt durch die Maschine dar.The drawing shows a longitudinal section through the machine.

Die Dampfturbine ι und der Stromerzeuger 2 sind in demselben Gehäuse 3 angeordnet, und liegen in derselben Mittelachse. Die Turbinenwelle 4 ist aus Stahl, die Stromerzeuger welle 5 aus Bronze hergestellt. Auf der Turbinenwelle 4 sitzt ferner ein Regler 6 bekannter Bauart (in der Zeichnung nur angedeutet). Die Turbinenwelle 4 ist nun mittelsThe steam turbine ι and the power generator 2 are arranged in the same housing 3, and lie in the same central axis. The turbine shaft 4 is made of steel, the power generator shaft 5 made of bronze. A regulator 6 is also seated on the turbine shaft 4 known design (only hinted at in the drawing). The turbine shaft 4 is now means

Die Verbindung der beiden Wellen 25 kann natürlich auch auf andere Weise ausgeführt werden.of the thread 7 screwed into the head 8 of the power 20 generator shaft 5; the screw connection is precisely centered by the conical contact surface 9 and riveted on both sides Cross bolt secured against rotation. The connection of the two shafts 25 can of course also be carried out in other ways.
