Description
Verfahren um Ringschmierlagermotoren auf Rollenlager umzubauen. Gewöhnlich werden Elektromotoren in Ringschmierlagern gelagert. Es sind auch .Konstruktionen bekannt geworden, die Lager als Kugellager auszubilden. Dagegen hat man bis jetzt noch nicht mit Ringschmier lagern ausgerüstete Motoren auf Kugellager umgebaut.
Gegenstand vorliegender Erfindung ist ein Verfahren um Ringschmierlagermotoren auf Rollenlagerung umzubauen.
Auf beiliegender Zeichnung ist ein Aus führungsbcispiel eines solchen auf Kugel- lagerung umgebauten Elektromotors im Schnitt dargestellt, an Hand welchem ein Verfahren zum Umbauen des Motors bei spielsweise erläutert wird. Dabei ist nur der erfindungsgemäss in Betracht kommende eine Lagerschild gezeigt. Gestrichelt ist die Kon tur des äussern Teils des ersetzten Ring- schmierla-gers angedeutet.
Vom -am Motorgehäuse 1 befestigten La gerschild 2 ist das Ringschmierlager 3 durch Absägen an der Schildfläche entfernt und der Schild bei 4 durchgebohrt. In die dadurch entstehende kreisförmige Öffnung wird eine Büchse 5 eingesetzt und mittels deren Flan schen 6 bei 7 mit dem Lagerschild 2 ver schraubt. Im Innern. der Büchse ist ein Ku gellager 8 eingesetzt und gegen Fettverlust durch einen Ring 9 gegen das Motorinnere abgedichtet.
Zweckmässigerweise ist dieser Dichtungsring mi-b einem Gewinde 10 ver sehen, um in der Büchse 5 eingeschraubt zu werden, wozu sich beispielsweise ein Steck schlüssel eignet.
Um das Kugellager zu schmieren, ist ein Auge 11 an -der Aussenseite der Büchse vor gesehen, in welchem ein Schmiernippel 12 einschraubbar ist, um das Schmiermittel durch einen Kanal dem Kugellager zuzu führen.
Die Vorteile. dieser Anordnung liegen leinmal in der Verkürzung der Motorwelle und dann hauptsächlich in der geringeren Wartung, weil man nicht immer wieder Schmieröl auswechseln muss, sondern nur in grossen Zeitabständen Fett in das Lager zu pressen hat. Ein weiterer Vorteil besteht darin, dass das Ausspritzen von<B>01</B> in das Innere :des Motors verhindert wird.
Ein weiterer Vorteil besteht darin, dass die Lager nicht nachgearbeitet werden müssen und sich auch ein Ausgiessen oder Ersetzen der Lagerschalen erübrigt.
Die beschriebene und gezeichnete Anord nung ist nur eine beispielsweise und lässt sich noch auf verschiedene andere- Arten lösen; so kann zum Beispiel die Büchse 5, statt sie auf den Lagerschild aufzuflanschen, in den selben eingeschraubt werden, oder es kann auch der ganze Lagerschild als Büchse aus gebildet werden.
Statt Kugellager können auch Walzen oder Nadellager verwendet werden. Die letzteren haben insbesondere den Vorteil der Raumersparnis in der Richtung des Durch messers.
Procedure for converting ring lubrication bearing motors to roller bearings. Electric motors are usually stored in ring lubrication bearings. There are also .Konstruktionen become known to train the bearings as ball bearings. In contrast, motors that have not yet been equipped with ring lubricant bearings have been converted to ball bearings.
The subject of the present invention is a method for converting ring lubrication bearing motors to roller bearings.
In the accompanying drawing, an exemplary embodiment of such an electric motor converted to ball bearings is shown in section, on the basis of which a method for converting the motor is explained, for example. Only the one end shield which is considered according to the invention is shown. The contour of the outer part of the replaced ring lubrication bearing is indicated by dashed lines.
From the bearing plate 2 attached to the motor housing 1, the lubricating ring bearing 3 is removed by sawing off the shield surface and the shield is drilled through at 4. In the resulting circular opening a sleeve 5 is inserted and screwed by means of their flan's 6 at 7 ver with the end shield 2. At the inside. the sleeve is a Ku gel bearing 8 is used and sealed against loss of fat by a ring 9 against the inside of the engine.
Appropriately, this sealing ring mi-b see a thread 10 ver to be screwed into the sleeve 5, for which a socket wrench is suitable, for example.
In order to lubricate the ball bearing, an eye 11 is seen on the outside of the bushing, in which a grease nipple 12 can be screwed to lead the lubricant through a channel to the ball bearing.
The advantages. This arrangement lies only in the shortening of the motor shaft and then mainly in the lower maintenance, because one does not have to change lubricating oil again and again, but only has to press grease into the bearing at long intervals. Another advantage is that <B> 01 </B> is prevented from spraying out into the interior of the motor.
Another advantage is that the bearings do not have to be reworked and there is no need to pour or replace the bearing shells.
The arrangement described and drawn is only an example and can be solved in various other ways; for example, the sleeve 5, instead of being flanged onto the bearing plate, can be screwed into the same, or the entire bearing plate can be formed as a sleeve.
Instead of ball bearings, rollers or needle bearings can also be used. The latter have the particular advantage of saving space in the direction of the diameter.
