DEUTSCHESGERMAN Häufig sind l>ei Werkz.eugspindeln, insbesondere spitzenlos er Schleifmaschinen, beiderseits des Werkzeugs ein Haupt lager und ein von einem Fassungsring umschlossenes Ausgleichslager angeordnet, wobei auf die Fassungsringe zwei radial zur Lagerachse gerichtete Federkräfte wirken, durch die die Spindel ständig gegen die Hauptlag-er gepreßt wird.Often there are one tool eye spindles, in particular centerless grinding machines, on both sides of the tool a main bearing and a compensating bearing enclosed by a mounting ring are arranged, wherein two spring forces directed radially to the bearing axis act on the mounting rings, through which the spindle is constantly pressed against the main bearing. Die Forderungen, die in der Fertigungstechnik an die Güte eines Werkstücks gestellt werden, sind vielfach sehr hoch, wobei Grundmaßabweichungen von nur wenigen Tausendstel Millimetern zugelassen sind. Für die Erzielung von Maßgenauigkeiten dieser Größenordnung ist es erforderlich, daß die verwendeten Werkzeugmaschinen gleichfalls, entsprechend geringe Lagerspiele aufweisen.The demands that are made in manufacturing technology the quality of a workpiece are often very high, with basic dimensional deviations of only a few thousandths of a millimeter are permitted. For achieving dimensional accuracy of these On the order of magnitude, it is necessary that the machine tools used are also correspondingly small Have bearing clearances. Die technische Entwicklung führt zu immer höheren Drehzahlen der Spindeln und damit zur erhöhten Beanspruchung der Lagerstellen, womit auch ein erhöhter Verschleiß an diesen Lagerstellen eintritt. Dies bedeutet gleichzeitig eime unerwünschte Erhöhung des Lagerspiefs und führt zu Schwingungen der Welle im Lager. Schwingungen der Welle sind l>ei der Feinstbearbeitung von großem Nachteil.The technical development leads to ever higher speeds of the spindles and thus to increased stress of the camps, which is also an increased Wear occurs at these bearing points. This also means an undesirable increase in the Bearing spief and leads to vibrations in the shaft Camp. Shaft vibrations are only used in fine machining of great disadvantage. Die bisherigen Vorschläge, -das Auftreten unzulässigen Lagerspiels durch radial zur Spindelachse wirkende federnde Mittel zu vermeiden, konnten nicht befriedigen, weil mit den entweder nur in einer Richtung oder in zwei zueinander senkrechten Richtungen wirkenden Druckkräften die bestehenden Mangel nicht abgestellt wurden bzw. sich keine einwandfreie Halterung der Spinde! in ihrer Arl>eitslage ergab.The previous proposals - the occurrence inadmissible It was not possible to avoid bearing play by resilient means acting radially to the spindle axis satisfy, because with the either only in one direction or in two mutually perpendicular directions acting pressure forces do not address the existing deficiency have been turned off or the lockers are not properly secured! in their position. Diese Nachteile werden gemäß der Erfindung dadurch behohen, daß auf jeden ein Ausgleichslager umschließenden Fassungsring zwei unter einem Winkel von annähernd 120° und symmetrisch zur Angrirrsstelle des Werkzeugs an dem Werkstück- angeordnete, federnde Mittel einwirken, durch die die Werkzeugspindel in vom Werkstück wegführender Richtung über die von den Fasbimgsringcn umschlossenen Ausgleichslager gegen die Hauptlager gedrückt wird. Auf diese Weise ergibt sich unter Berücksichtigung des natürlichen Lagerverschleißes eine vollkommen spielfreie Lagerung für Werkzeug-, z. 11 Schleifscheiben spindeln. These disadvantages are compensated according to the invention in that a compensating bearing enclosing each Mounting ring two at an angle of approximately 120 ° and symmetrical to the contact point of the tool on the workpiece - arranged, Resilient means act through which the tool spindle in the direction leading away from the workpiece via the compensating bearings enclosed by the Fasbimgsringcn is pressed against the main bearing. In this way, taking into account the natural bearing wear a completely play-free storage for tool, z. 11 spindles grinding wheels.
