Description

Vorrichtung zur Verhütung der Standriefenbildung in Wälzlagern von Maschinen Die Erfindung bezieht sich auf eine Vorrichtung zur Verhütung von Standriefenbildung in Wälzlagern von -Maschinen, insbesondere elektrischen Maschinen, während des Stillstandes der Maschine nach Patentanmeldung S 46460 XII/47b. Die Spannvorrichtung kann nach der Hauptpatentanmeldung beispielsweise aus einem über das Wellenende gestülpten Topf bestehen, gegen dessen Boden eine an die Wellenstirne angeschraubte Spannschraube drückt und dessen Rand sich an Gehäuseteilen abstützt. Eine solche Spannvorrichtung muß bei Inbetriebnahme der Maschine entfernt werden und ist auch bei eingeschalteter Maschine wirksam, wenn sie versehentlich nicht vorher abgenommen wird.Device for preventing standing scoring in rolling bearings from Machines The invention relates to a device for preventing standing scoring in roller bearings of machines, especially electrical machines, during standstill the machine according to patent application S 46460 XII / 47b. The jig can after the main patent application, for example, from a slipped over the shaft end Pot exist, against the bottom of a clamping screw screwed to the shaft end presses and the edge of which is supported on housing parts. Such a jig must be removed when the machine is started up and is also switched on when the Machine effective if it is accidentally not removed beforehand.

Dieser Nachteil wird durch die Erfindung vermieden. Erfindungsgemäß ist ein ein axial bewegliches Verspannungsorgan aus der Verspannungsstellung gegen die Wirkung einer Feder od. dgl. lüftender Elektromagnet angeordnet, dessen Erregerwicklung mit der Maschine ein- und ausgeschaltet wird. Zweckmäßig bildet das als Bolzen ausgebildete Verspannungsorgan den Anker des Elektromagneten.This disadvantage is avoided by the invention. According to the invention is an axially movable bracing member from the braced position against the action of a spring or the like. Arranged releasing electromagnet, its excitation winding is switched on and off with the machine. Expediently forms that designed as a bolt Bracing organ is the armature of the electromagnet.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Sie zeigt eine Verspannungseinrichtung im Längsschnitt.An exemplary embodiment of the invention is shown in the drawing. It shows a bracing device in a longitudinal section.

Die Maschinenwelle 1 ist mittels eines Kugellagers 2 in dem Lagerschild 3 einer nicht weiter dargestellten elektrischen Maschine gelagert. Der äußere Lagerdeckel 4 bildet zugleich das Gehäuse eines Elektromagneten 5, dessen Erregerwicklung 6 mit der Maschine ein- und ausgeschaltet wird. Ein sich mittels einer Druckfeder 7 an dem Gehäusedeckel abstützender Bolzen 8, der von der Feder 7 gegen die Wellenstirne 9 gedrückt wird, bildet gleichzeitig den Anker des Elektromagneten. Bei eingeschalteter Maschine und eingeschalteter Erregerwicklung wird der Anker gegen die Wirkung der Feder 7 von der Wellenstirne 9 weggezogen und damit die Verspannung gelöst. Der Elektromagnet könnte auch über ein übersetzungsgestänge auf die Verspannungseinrichtung einwirken.The machine shaft 1 is in the end shield by means of a ball bearing 2 3 mounted an electrical machine not shown. The outer bearing cap 4 at the same time forms the housing of an electromagnet 5, its excitation winding 6 is switched on and off with the machine. One itself by means of a compression spring 7 on the housing cover supporting bolt 8, which is held by the spring 7 against the shaft face 9 is pressed, at the same time forms the armature of the electromagnet. When switched on Machine and energized field winding is the armature against the action of the Spring 7 pulled away from the shaft end 9 and thus released the tension. Of the Electromagnet could also act on the bracing device via a transmission linkage act.

Die Erfindung bietet den Vorteil, daß nicht nur die Verspannung bei eingeschalteter Maschine selbsttätig aufgehoben, sondern auch die Verspannung bei abgeschalteter Maschine selbsttätig wirksam wird. Außerdem bleibt die Verspannungseinrichtung auch während des Betriebes mit der Maschine baulich verbunden.The invention offers the advantage that not only the tension at automatically lifted when the machine is switched on, but also the tension at automatically becomes effective after the machine is switched off. In addition, the bracing device remains also structurally connected to the machine during operation.
