Description

  

      Schleifmaschine.       Gegenstand vorliegender Erfindung ist eine  Schleifmaschine, deren Schleifspindel mit  einem Motor direkt gekuppelt ist.  



  Bisher waren die Schleifspindeln in sol  chen Maschinen nur zweifach gelagert. Das  hat den Nachteil, dass der Anker des Motors  leicht in Schwingung gerät, was sich in einem  unruhigen Gang der Schleifspindel bemerkbar  macht. Solche Maschinen sind daher für Prä  zisionsarbeiten ungeeignet.  



  Erfindungsgemäss wird dieser Übelstand  dadurch behoben, dass die     Schleifspindel    drei  fach gelagert ist. Vorzugsweise geschieht dies  so, dass die Lagerung der Schleifspindel auf  der einen Seite des Motors mittels     zweier     nachstellbarer Gleitlager, auf der andern Seite  des Motors hingegen mittels eines Wälzlagers  erfolgt.  



  Beiliegende Zeichnung zeigt     eine    beispiels  weise     Ausführungsform    des Erfindungsgegen  standes. Darin stellt die     einzige    Figur einen  Achsialschnitt durch den Spindelsupport der  Schleifmaschine dar.    Die die Schleifscheibe 1 tragende Schleif  spindel 2 ist auf der einen Seite des Motors 3  mittels der nachstellbaren Bronzegleitlager 4  und 5 und auf der andern Seite des Motors 3  mittels des aus einem Kugellager 6 beste  henden Wälzlagers im Schleifsupport gelagert.  Letzterer besteht aus den Teilen 7 und 8, die  sich in einer zur Schleifspindelachse senk  rechten Ebene berühren. Die beiden Teile 7  und 8 bilden miteinander einen Hohlraum 9,  in welchem der Motor 3 untergebracht ist.

    Der     Stator    10 des Motors ist mit den Sup  portteilen 7 und 8 verschraubt. Dank der  gezeigten dreifachen Lagerung können     Anker-          schwingungen    vermieden werden und der Gang  der Spindel 2 ist leicht und ruhig, so     dass     sich die Schleifmaschine sehr gut für Präzi  sionsarbeiten eignet.



      Grinding machine. The present invention relates to a grinding machine whose grinding spindle is directly coupled to a motor.



  So far, the grinding spindles in such machines were only stored twice. This has the disadvantage that the armature of the motor easily starts to vibrate, which is noticeable in the uneven speed of the grinding spindle. Such machines are therefore unsuitable for precision work.



  According to the invention, this drawback is eliminated in that the grinding spindle is supported three times. This is preferably done in such a way that the grinding spindle is mounted on one side of the motor by means of two adjustable slide bearings, while on the other side of the motor it is by means of a roller bearing.



  The accompanying drawing shows an example embodiment of the subject matter of the invention. Therein the only figure represents an axial section through the spindle support of the grinding machine. The grinding spindle 2 carrying the grinding wheel 1 is on one side of the motor 3 by means of the adjustable bronze sliding bearings 4 and 5 and on the other side of the motor 3 by means of a ball bearing 6 existing rolling bearings stored in the grinding support. The latter consists of parts 7 and 8, which touch in a right plane perpendicular to the grinding spindle axis. The two parts 7 and 8 together form a cavity 9 in which the motor 3 is accommodated.

    The stator 10 of the motor is screwed to the support parts 7 and 8. Thanks to the triple bearing shown, armature vibrations can be avoided and the speed of the spindle 2 is easy and quiet, so that the grinding machine is very well suited for precision work.
