Abstract
Vakuumpumpe, insbesondere Flügelzellenpumpe, mit einem Rotorlagerabschnitt (10; 30; 50), mit dem ein Rotor (4; 24; 44) um eine Drehachse drehbar in einem Gehäuselagerabschnitt (15; 35; 55) eines Gehäuses (5; 25; 45) gelagert ist, wobei in mindestens einem der Lagerabschnitte (10, 15; 30, 35; 50, 55) eine Ringnut (18; 38; 58) vorgesehen ist, die zur Aufnahme von Schmier- und/oder Dichtmittel dient dadurch gekennzeichnet, dass die Ringnut (38) in dem Gehäuselagerabschnitt (35) vorgesehen ist oder die Ringnut (58) in axialer Richtung von einem Absatz (57) des Gehäuselagerabschnitts (55) und einem Absatz (56) des Rotorlagerabschnitts (50) begrenzt wird. Vacuum pump, in particular a vane pump, with a rotor bearing section (10; 30; 50), with which a rotor (4; 24; 44) is rotatable about a rotation axis in a housing bearing section (15; 35; 55) of a housing (5; 25; 45) is provided, wherein in at least one of the bearing portions (10, 15, 30, 35, 50, 55) an annular groove (18, 38, 58) is provided, which serves to receive lubricant and / or sealant, characterized in that the Ring groove (38) in the housing bearing portion (35) is provided or the annular groove (58) in the axial direction of a shoulder (57) of the housing bearing portion (55) and a shoulder (56) of the rotor bearing portion (50) is limited.
Description
Die Erfindung betrifft eine Vakuumpumpe, insbesondere eine Flügelzellenpumpe, mit einem Rotorlagerabschnitt, mit dem ein Rotor um eine Drehachse drehbar in einem Gehäuselagerabschnitt eines Gehäuses gelagert ist. The invention relates to a vacuum pump, in particular a vane pump, with a rotor bearing portion, with which a rotor is rotatably mounted about a rotation axis in a housing bearing portion of a housing.

Aus der
Die Aufgabe ist bei einer Vakuumpumpe, insbesondere einer Flügelzellenpumpe, mit einem Rotorlagerabschnitt, mit dem ein Rotor um eine Drehachse drehbar in einem Gehäuselagerabschnitt eines Gehäuses gelagert ist, dadurch gelöst, dass in mindestens einem der Lagerabschnitte eine Ringnut vorgesehen ist, die zur Aufnahme von Schmier- und/oder Dichtmittel dient. Durch die Ringnut wird die Versorgung der Lagerabschnitte mit Schmier- und/oder Dichtmittel verbessert. Bei dem Schmier- und/oder Dichtmittel handelt es sich vorzugsweise um Öl, das zur Schmierung der Lagerabschnitte dient. Darüber hinaus dient das Öl dazu, den Ringspalt oder Lagerschmierspalt beziehungsweise Lagerspalt zwischen den Lagerabschnitten abzudichten. The object is in a vacuum pump, in particular a vane pump, with a rotor bearing portion, with which a rotor is rotatably mounted about a rotation axis in a housing bearing portion of a housing, achieved in that in at least one of the bearing portions an annular groove is provided which is for receiving lubricant - and / or sealant is used. The annular groove improves the supply of the bearing sections with lubricants and / or sealants. The lubricating and / or sealing agent is preferably oil which serves to lubricate the bearing sections. In addition, the oil serves to seal the annular gap or bearing lubrication gap or bearing gap between the bearing sections.
Weitere bevorzugte Ausführungsbeispiele der Vakuumpumpe sind dadurch gekennzeichnet, dass die Ringnut in dem Rotorlagerabschnitt oder in dem Gehäuselagerabschnitt vorgesehen ist. Die Ringnut hat zum Beispiel einen rechtwinkligen Querschnitt. Further preferred embodiments of the vacuum pump are characterized in that the annular groove is provided in the rotor bearing portion or in the housing bearing portion. The annular groove has, for example, a rectangular cross-section.
Ein weiteres bevorzugtes Ausführungsbeispiel der Vakuumpumpe ist dadurch gekennzeichnet, dass die Ringnut in axialer Richtung von einem Absatz des Gehäuselagerabschnitts und einem Absatz des Rotorlagerabschnitts begrenzt wird. Als axiale Richtung wird eine Richtung parallel zur Rotordrehachse bezeichnet. A further preferred embodiment of the vacuum pump is characterized in that the annular groove is bounded in the axial direction by a shoulder of the housing bearing section and a shoulder of the rotor bearing section. The axial direction is a direction parallel to the rotor axis of rotation.
Ein weiteres bevorzugtes Ausführungsbeispiel der Vakuumpumpe ist dadurch gekennzeichnet, dass die Ringnut in radialer Richtung von dem Rotorlagerabschnitt und dem Gehäuselagerabschnitt begrenzt wird. Das hat den Vorteil, dass keine Nut in die Lagerabschnitte eingearbeitet werden muss. A further preferred embodiment of the vacuum pump is characterized in that the annular groove is bounded in the radial direction by the rotor bearing portion and the housing bearing portion. This has the advantage that no groove must be incorporated into the bearing sections.
Ein weiteres bevorzugtes Ausführungsbeispiel der Vakuumpumpe ist dadurch gekennzeichnet, dass ein Versorgungskanal in die Ringnut mündet. Durch den Versorgungskanal wird der Ringnut Schmier- und/oder Dichtmittel zugeführt. A further preferred embodiment of the vacuum pump is characterized in that a supply channel opens into the annular groove. Through the supply channel of the annular groove lubricants and / or sealant is supplied.
Ein weiteres bevorzugtes Ausführungsbeispiel der Vakuumpumpe ist dadurch gekennzeichnet, dass der Versorgungskanal in dem Gehäuse ausgespart ist. Der Versorgungskanal ist zum Beispiel an die Ölversorgung einer Brennkraftmaschine angeschlossen. Der Versorgungskanal ist vorzugsweise als Bohrung ausgeführt. Another preferred embodiment of the vacuum pump is characterized in that the supply channel is recessed in the housing. The supply channel is connected, for example, to the oil supply of an internal combustion engine. The supply channel is preferably designed as a bore.
Ein weiteres bevorzugtes Ausführungsbeispiel der Vakuumpumpe ist dadurch gekennzeichnet, dass der Rotor mindestens einen Flügel aufweist, der einen Arbeitsraum in dem Gehäuse in einen Saugraum und einen Druckraum unterteilt. Der Aufbau und die Funktion einer Flügelzellenpumpe sind bekannt. Das Gehäuse kann ein- oder mehrteilig ausgeführt sein. A further preferred embodiment of the vacuum pump is characterized in that the rotor has at least one wing which divides a working space in the housing into a suction chamber and a pressure chamber. The structure and function of a vane pump are known. The housing can be made in one or more parts.
