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.
