Description
Einrichtung zur Verhinderung des Kriechens von Öl auf einer Welle Die Erfindung geht von einer Einrichtung zur Verhinderung des Kriechens von Öl auf einer mit einer Spritzkante versehenen Welle, insbesondere Turbinenwelle, aus.Device for preventing oil from creeping on a shaft The invention relates to a device for preventing oil from creeping a shaft provided with a spray edge, in particular a turbine shaft.
Es sind hinter der Spritzkante oder Spritzmasse angebrachte Einsatz- oder Dichtringe bekannt, die die Aufgabe haben, das von der Spritzkante abgeschleuderte, sich in dem ölauffangraum verteilende und in Form von Nebel oder Tropfen zur Welle zurückkommende Öl abzustreifen.There are insert installed behind the spray edge or spray compound. or sealing rings known, which have the task of throwing off the spray edge, spreading in the oil collecting space and in the form of mist or drops to the wave to strip off returning oil.
Da bei der bisherigen Anordnung die vorgeschriebene Fassung der Bohrung der Einsatz- oder Dichtringe mit Bezug zur Welle entweder nicht eingehalten werden kann oder durch das Vibrieren der Welle zerstört wird, ergibt sich infolgedessen ein zu großes Spiel zwischen Bohrung und Welle, wodurch das Abstreifen des Öles nicht mehr gewährleistet ist und dadurch austretendes Öl mit dampf- oder stromführenden Teilen der Maschine in betriebsgefährdender Weise in Berührung kommen kann.As in the previous arrangement, the prescribed version of the hole the insert or sealing rings with reference to the shaft are either not adhered to may or may be destroyed by the vibration of the shaft, results as a result too much play between the bore and the shaft, which means that the oil is stripped off is no longer guaranteed and the resulting oil with steam or current carrying Parts of the machine can come into contact in an operationally hazardous manner.
Der Erfindung liegt die Aufgabe zugrunde, diese Nachteile der bekannten Ausführung zu beseitigen.The invention is based on these disadvantages of the known To eliminate execution.
Die Erfindung geht von der Erkenntnis aus, daß es wichtig ist, das von der Welle durch eine erhöht ausgebildete- Spritzkante abgeschleuderte Öl aufzufangen und es daran zu hindern, in irgendeiner Form zur Welle zurückzukehren. Dies geschieht erfindungsgemäß durch rings oberhalb der Spritzkante der Welle angeordnete, vom oberen Scheitelpunkt des Ölauffangraumes nach beiden Seiten abfallende, sich dachziegelartig mit Abstand überdeckende Ölfang- und Ölleitplatten.The invention is based on the recognition that it is important to catch the oil thrown off the shaft by a raised spray edge and to prevent it from returning to the shaft in any way. This is done according to the invention by means of oil catcher and oil guide plates which are arranged around above the splash edge of the shaft, sloping from the upper apex of the oil collecting space to both sides and overlapping at a distance like roof tiles.
Ein weiteres Merkmal der Erfindung besteht darin, die Fang- und Leitplatten an einer Blechringhälfte oder zwischen zwei Blechringhälften zu befestigen.Another feature of the invention is the catch and guide plates to be attached to a sheet metal ring half or between two sheet metal ring halves.
Nachstehend wird die Erfindung an Hand eines in der Zeichnung in zwei Ansichten dargestellten Ausführungsbeispieles erläutert: Die Einrichtung zur Verhinderung des Kriechens von Öl auf einer Welle, insbesondere Turbinenwelle, besteht aus den Blechringhälften 1 und 2. Zwischen diesen Blechringhälften 1 und 2 sind rings oberhalb der Spritzkante 3 der Welle 4 vom oberen Scheitelpunkt des ölauffangraumes 5 nach beiden Seiten abfallende, sich dachziegelartig mit Abstand überdeckende Ölfang- und ölleitplatten 6 angeordnet. Das von der Welle 4 unter einem kleinen Winkel an die Fang- und Leitplatten 6 spritzende Öl bleibt an der der Welle 4 zugewandten Seite der Fang- und Leitplatte 6 haften und läuft auf Grund der dachziegelartigen Anordnung der Fang- und Leitplatten 6 auf die der Welle 4 abgewandten Seite der nächstfolgenden Fang- und Leitplatten 6.The invention is illustrated in two by way of one in the drawing Views illustrated embodiment explained: The device for prevention the creeping of oil on a shaft, especially a turbine shaft, consists of the Sheet metal ring halves 1 and 2. Between these sheet metal ring halves 1 and 2 are rings above the splash edge 3 of the shaft 4 from the upper apex of the oil collecting space 5 after sloping on both sides, overlapping like roof tiles at a distance and oil guide plates 6 arranged. That from the shaft 4 at a small angle the oil spraying the catch and guide plates 6 remains on the one facing the shaft 4 Side of the catch and guide plate 6 adhere and run due to the tile-like Arrangement of the catch and guide plates 6 on the side facing away from the shaft 4 Next catch and guide plates 6.
Diese Einrichtung hat den Vorteil, daß durch das frühzeitige Auffangen des von der Spritzkante abgeschleuderten Öles es nicht zur Bildung von Öldunst kommt und das Öl nicht wieder auf die Welle zurückfällt.This facility has the advantage that it is caught at an early stage of the oil thrown off the splash edge, there is no formation of oil vapor and the oil doesn't fall back on the shaft.
