Description

Gegenstand des Patents 879 9'39 -ist eine Wellen= dicbtung insbesondere für schnell laufende Wellten, mit durch einen Ring aus festerem Werkstoff an die W@cAle gepreßter elastischer Dichtlippe.The subject of patent 879 939 is a wave seal in particular for high-speed corrugations, with a ring made of stronger material to the W @ cAle pressed elastic sealing lip.

Es hat sich nämlich ergeben, daß eine ein%van@dfreie Wellendichtung nur dann erzielt werden kann, wenn die bekannten federnden Anpreßringe für die Dichtlippe .durch einen aus festem Werkstoff bestehenden Ring, beispielsweise durch ein ringsum geschlossenes Metallhand, ersetzt werden, das die Lippe ganz oder teilweise umgibt. Ers ist dann allerdings erforderlich, den Innendurchmesser der Wellendichtung auszuschleifen, was wiederum eine engere Ringtoleranz zur Folge hat.It has namely been found that a% van @ d-free shaft seal can only be achieved if the known resilient pressure rings for the sealing lip .by a ring made of solid material, for example by an all around closed metal hand, which completely or partially surrounds the lip. However, it is then necessary to grind out the inner diameter of the shaft seal, which in turn results in a tighter ring tolerance.

Bei der weiteren Ausgestaltung der Wellendichtung nach Patent 879 939= wie sie Gegenstand dieser Erfindung ist, behält der Lippenteil der Dichtung auch bei der Verwendung eines in sich geschlossenen Ringes eine gute Elastizität. Erreicht wird das dadurch, @daß als Ring ein flaches Metallband benutzt und die an der Welle anliegende Dichtungslippe mit einer kammerartigen Aussparung versehen wird, die gleich breit oder breiter isst als dass Metallband. Dabei besteht die Möglichkeit, den dem abzudichtenden Mittel zugekehrten und vor dem Metallring gelegenen Teil der Dichtlippe noch durch eine Ringwendelfeder an die Welle anzupressen.In the further development of the shaft seal according to patent 879 939 = as it is the subject of this invention, the lip part of the seal retains good elasticity even when using a self-contained ring. This is achieved by @ that a flat metal band is used as a ring and the Provide the sealing lip resting on the shaft with a chamber-like recess that eats the same width or wider than the metal band. There is the Possibility of facing the means to be sealed and located in front of the metal ring Press part of the sealing lip onto the shaft using a helical spring.

Bei der Wellendichtung nach .dieser Erfindung wird dem Dichtlippentefl die Möglichkeit gegeben, auch bei stärkeren Radialschwingungen der Welle stets am Wellenumfang anzuliegen, ohne daß ,die Elastizität des Dichtlippenteils beeinträchtigt wird.In the case of the shaft seal according to this invention, the sealing lip tefl given the possibility, even with stronger radial vibrations of the shaft, always on To lie against the circumference of the shaft without affecting the elasticity of the sealing lip part will.

In der Zeichnung ist die Wellendichtung nach der Erfindung an einem Ausführungsbeispiel dargestellt.In the drawing, the shaft seal according to the invention is on one Embodiment shown.

Die Welle i ist von einem Dichrlippenteid' 3 umgeben, der eine kammerartige Aussparung :2 aufweist und durch einen in sich geschlossenen Metallring q. an die Welle angedrückt wird. Der Verbindungsteil 5 der Dichtung ist in bekannter Weise mit dem von einem Winkelring 6 umgebenen Haftteil 7 verbunden und die Wellendichtung insgesamt in den -1@I,aschinenteil 8 ei.ngepreßt. Im gezeichneten Fall ist die in der Dichtungslippe vorgesehene Ausnehmung 2 länger als das Metallband q. breit ist.The shaft i is surrounded by a Dichrlippenteid '3, which is a chamber-like Recess: 2 and by a self-contained metal ring q. to the Shaft is pressed. The connecting part 5 of the seal is in a known manner connected to the adhesive part 7 surrounded by an angle ring 6 and the shaft seal pressed together in the -1 @ I, machine part 8. In the case shown, the in the sealing lip provided recess 2 longer than the metal band q. is wide.
