Description

Vorrichtung zur Verhütung vnn 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, 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 to prevent 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 consist, the bottom of which has a clamping screw screwed to the end of the shaft 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 die Maschine über ein Schütz od. dgl. abschaltender Kontakt angeordnet, der durch die axiale Bewegung der Verspannungseinrichtung geschlossen wird. Zweckmäßig ist der Kontakt an der der einen Stirnfläche der Maschinenwelle zugekehrten Stirnfläche einer Spannschraube angeordnet, die in Verlängerung der Maschinenwelle in ein Gehäuseteil eingeschraubt und vorzugsweise mittels eines Handrades verstellbar ist.This disadvantage is avoided by the invention. According to the invention a contact that switches off the machine via a contactor or the like is arranged, which is closed by the axial movement of the bracing device. Appropriate is the contact on the end face facing one end face of the machine shaft a clamping screw arranged, which is in extension of the machine shaft in a housing part is screwed in and preferably adjustable by means of a handwheel.

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. In den äußeren Lagerdeckel 4 ist eine mit einem Handrad 5 aus einem Stück bestehende Spannschraube 6 eingeschraubt, die unter Zwischenlage einer Isolation 7 ein Druckstück 8 umfaßt. In diesem Druckstück ist ein Kontakt 9 angeordnet, der beim Einschrauben der Spannschraube mittels des Handrades gegen die Wellenstirne 10 gedrückt wird und damit einen Stromkreis 11 schließt, der über ein Schütz die Maschine abschaltet.The machine shaft 1 is in the end shield by means of a ball bearing 2 3 mounted an electrical machine not shown. In the outer Bearing cover 4 is a clamping screw consisting of a handwheel 5 in one piece 6 screwed in, which includes a pressure piece 8 with the interposition of insulation 7. In this pressure piece, a contact 9 is arranged, which when the clamping screw is screwed in is pressed by means of the handwheel against the shaft end 10 and thus a circuit 11 closes, which switches off the machine via a contactor.

Die Erfindung bietet den Vorteil, daß die Maschine nur eingeschaltet werden kann, wenn die Verspannung gelöst ist. Außerdem bleibt die Verspannungseinrichtung auch während des Betriebes mit der Maschine baulich verbunden.The invention offers the advantage that the machine is only switched on can be when the tension is released. In addition, the bracing device remains also structurally connected to the machine during operation.
