Description

Das Patent 924665 betrifft eine Sicherheitsvorrichtung zum Schutz von Wälzlagern gegen Schäden durch Stöße, Erschütterungen od. dgl. beim Transport. Gemäß der Erfindung des Hauptpatents werden der feste und der umlaufende Teil des Lagers beim Transport durch eine eingefügte keilförmige Anordnung gegeneinander versteift. Und zwar besteht die eingefügte keilförmige Anordnung dort aus einer konischen Kappe, die über die Motorwelle geschoben und mit ihrem konischen Teil in den Spalt zwischen dem feststehenden und dem umlaufenden Teil des Wälzlagers gepreßt wird. Eine solche Sicherheitsvorrichtung kann jedoch nicht verwendet werden, wenn auf der Motorwelle bereits .eine Riemenscheibe oder eine Kupplung befestigt worden ist, weil die über die Motorwelle zu schiehende konische Kappe nur einen begrenzten Innendurchmesser haben kann.Patent 924665 relates to a safety device for protection of rolling bearings against damage from impacts, vibrations or the like during transport. According to the invention of the main patent, the fixed and the rotating part of the Bearing against each other during transport by an inserted wedge-shaped arrangement stiffened. The wedge-shaped arrangement inserted there consists of one conical cap that is pushed over the motor shaft and with its conical part into the gap between the fixed and the rotating part of the roller bearing is pressed. However, such a safety device cannot be used if a belt pulley or coupling is already attached to the motor shaft because the conical cap to be pulled over the motor shaft is only one may have limited inner diameter.

Erfindungsgemäß wird dieser Mangel dadurch beseitigt, daß ringsektorförmige Teile mit konischen Ansätzen in den Spalt zwischen dem feststehenden und dem umlaufenden Teil des Wälzlagers gepreßt werden. Eine solche Sicherheitsvorrichtung braucht dann nicht mehr auf die Motorwelle aufgeschoben zu werden, sondern wird unmittelbar vor dem zu sichernden Wälzlager auf die Welle gelegt und dort um :den geringen, für das Festspannen der Sicherheitsvorrichtung erforderlichen. Weg axial verschoben. In den Fig. I und 2 wird ein Ausführungsbeispiel der erfindungsgemäßen Sicherheitsvorrichtung dargestellt. Das zu sichernde Wälzlager besteht aus einem in den Lagerschild I eines Motors eingelegten Außenring 2 und einem auf der Motorwelle 3 angebrachten Innenring 4. Zwischen den beiden Ringen befinden sich die Wälzkörper 5, und zwischen diesen. Teilen ist das durch die üblichen -Toleranzen vorgeschriebene Spiel in radialer Richtung vorhanden. Der Außenring 2 wird in Achsrichtung durch einen am Lagerschild I angeschraubten und zentrierten festen Teil in Form einer Platte 6 gehalten. Der mit der Motorwelle 3 umlaufende Ring 4 wird in Achsrichtung durch einen mit dieser verbundenen Teil 7 gehalten. Beide Teile 6 und 7 greifen, wie .die Zeichnung zeigt, ineinander, haben aber in radialer Richtung gegeneinander ein Spiel, das größer ist und größer sein muß als die beim eigentlichen Wälzlager vorhandenen Toleranzen. Gemäß der Erfindung des Hauptpatents ist das. in den Spalt zwischen dem feststehenden Teil 6 und dem umlaufenden Teil 7 gepreßte Teil 8 eine konische Kappe. Da sich bei dem Ausführungsbeispiel auf .der Motorwelle 3 jedoch ein Kupplungsflansch 9 befindet, ist es hier nicht möglich, eine konische Kappe über die Motorwelle 3 zu schieben, sondern der Teil 8 wird erfindungsgemäß als Ringsektorstück mit einem konischen Ansatz ausgebildet, wie die Fig. 2 zeigt.According to the invention, this deficiency is eliminated in that ring sector-shaped Parts with conical lugs in the gap between the fixed and the rotating one Part of the rolling bearing are pressed. Such a safety device then needs no longer to be pushed onto the motor shaft, but is immediately in front of the roller bearing to be secured is placed on the shaft and there around: the small one, for the tightening of the safety device is necessary. Axially shifted path. In Figs. I and 2, an embodiment of the safety device according to the invention shown. The rolling bearing to be secured consists of one in the end shield I. Motor inserted outer ring 2 and an inner ring attached to the motor shaft 3 4. The rolling elements 5 are located between the two rings, and between them. Dividing is the radial clearance prescribed by the usual tolerances Direction present. The outer ring 2 is in the axial direction by a on the end shield I screwed and centered fixed part held in the form of a plate 6. Of the with the motor shaft 3 rotating ring 4 is in the axial direction by a with this connected part 7 held. Both parts 6 and 7 grip, as the drawing shows into each other, but have a greater play against each other in the radial direction and must be greater than the tolerances in the actual rolling bearing. According to the invention of the main patent that is. In the gap between the fixed Part 6 and the circumferential part 7 pressed part 8 a conical cap. As with In the exemplary embodiment, however, there is a coupling flange 9 on the motor shaft 3, it is not possible here to slide a conical cap over the motor shaft 3, but the part 8 is according to the invention as a ring sector piece with a conical Approach formed, as FIG. 2 shows.

Je nach der Größe des Zentriwinkels, über den sich .ein solches Ringsektorstück erstreckt, können zwei oder mehrere solcher Teile auf dem Umfang der Motorwelle 3 verteilt angeordnet werden. Von dem in Fig. z als Ausführungsbeispiel gezeigten Ringsektorstück, das einen Zentriwinkel von weniger als I2o° bedeckt, können drei solcher Ringsektorstücke zur Sicherung des Wälzlagers auf dem Umfang der Motorwelle 3 angeordnet und durch Anziehen der Schrauben io mit ihren konischen Ansätzen in den Spalt zwischen den Teilen 6 und 7 gepreßt werden.Depending on the size of the central angle over which. Such a ring sector piece extends, two or more such parts can be on the circumference of the motor shaft 3 can be arranged in a distributed manner. From that shown in Fig. Z as an embodiment Ring sector piece that covers a central angle of less than I2o ° can have three such ring sector pieces to secure the roller bearing on the circumference of the motor shaft 3 and by tightening the screws io with their conical lugs in the gap between the parts 6 and 7 are pressed.
