Abstract
Die Erfindung betrifft eine Abdichtanordnung (24) einer Welle (14) an einem Gehäuseelement (18) eines Abgasturboladers, bei welcher wenigstens zwei in axialer Richtung der Welle (14) aufeinanderfolgende Dichtringe (26, 28) vorgesehen sind, mittels welchen die um eine Drehachse (20) relativ zu dem Gehäuseelement (18) drehbare Welle (14) gegen das Gehäuseelement (18) abgedichtet ist, wobei in axialer Richtung zwischen den Dichtringen (26, 28) wenigstens ein Distanzring (36) angeordnet ist.The invention relates to a sealing arrangement (24) of a shaft (14) on a housing element (18) of an exhaust gas turbocharger, in which at least two successive sealing rings (26, 28) in the axial direction of the shaft (14) are provided, by means of which the about an axis of rotation (20) relative to the housing member (18) rotatable shaft (14) is sealed against the housing member (18), wherein in the axial direction between the sealing rings (26, 28) at least one spacer ring (36) is arranged.
Description
Die Erfindung betrifft eine Abdichtanordnung einer Welle an einem Gehäuseelement eines Abgasturboladers gemäß dem Oberbegriff vom Patentanspruch 1.The invention relates to a sealing arrangement of a shaft on a housing element of an exhaust gas turbocharger according to the preamble of patent claim 1.
Derartige Abdichtanordnungen von Wellen an Gehäuseelementen von Abgasturboladern sind aus dem allgemeinen Stand der Technik und insbesondere aus dem Serienfahrzeugbau bereits hinlänglich bekannt. Ein solcher Abgasturbolader kommt üblicherweise bei einer Verbrennungskraftmaschine zum Einsatz, sodass die Verbrennungskraftmaschine mittels des Abgasturboladers mit verdichteter Luft versorgt werden kann.Such Abdichtanordnungen of waves on housing elements of exhaust gas turbochargers are already well known from the general state of the art and in particular from the production of standard vehicles. Such an exhaust gas turbocharger is usually used in an internal combustion engine, so that the internal combustion engine can be supplied by means of the exhaust gas turbocharger with compressed air.
Der Abgasturbolader umfasst üblicherweise einen sogenannten Rotor, welcher die zuvor genannte Welle und wenigstens ein Laufrad umfasst. Das Laufrad ist drehfest mit der Welle verbunden. Die Welle ist üblicherweise an dem Gehäuseelement um eine Drehachse relativ zu dem Gehäuseelement drehbar gelagert, sodass der Rotor über die Welle drehbar an dem Gehäuseelement gelagert ist. Bei der Abdichtanordnung sind wenigstens zwei in axialer Richtung der Welle aufeinanderfolgende beziehungsweise hintereinander angeordnete Dichtringe vorgesehen, mittels welchen die um die Drehachse relativ zu dem Gehäuseelement drehbare Welle gegen das Gehäuseelement abgedichtet ist. Bei dem Gehäuseelement handelt es sich üblicherweise um ein sogenanntes Lagergehäuse des Abgasturboladers, wobei die Welle, insbesondere über wenigstens ein Lagerelement drehbar, an dem Lagergehäuse gelagert und durch die Dichtringe gegen das Lagergehäuse abgedichtet ist.The exhaust gas turbocharger usually comprises a so-called rotor, which comprises the aforementioned shaft and at least one impeller. The impeller is rotatably connected to the shaft. The shaft is usually rotatably mounted on the housing element about an axis of rotation relative to the housing element, so that the rotor is rotatably mounted on the housing element via the shaft. In the case of the sealing arrangement, at least two sealing rings arranged one after the other in the axial direction of the shaft are provided, by means of which the shaft rotatable about the axis of rotation relative to the housing element is sealed against the housing element. The housing element is usually a so-called bearing housing of the exhaust gas turbocharger, wherein the shaft, in particular via at least one bearing element rotatably mounted on the bearing housing and sealed by the sealing rings against the bearing housing.
Aufgabe der vorliegenden Erfindung ist es, eine Abdichtanordnung der eingangs genannten Art derart weiterzuentwickeln, dass der Verschleiß der Abdichtanordnung besonders gering gehalten werden kann.Object of the present invention is to develop a sealing arrangement of the type mentioned in such a way that the wear of the sealing arrangement can be kept particularly low.
Diese Aufgabe wird durch eine Abdichtanordnung mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen mit zweckmäßigen Weiterbildungen sind in den übrigen Ansprüchen angegeben.This object is achieved by a sealing arrangement having the features of patent claim 1. Advantageous embodiments with expedient developments are specified in the remaining claims.
Um eine Abdichtanordnung der im Oberbegriff des Patentanspruchs 1 angegebenen Art derart weiterzuentwickeln, dass der Verschleiß der Abdichtanordnung besonders gering gehalten werden kann, ist es erfindungsgemäß vorgesehen, dass in axialer Richtung zwischen den Dichtringen wenigstens ein Distanzring angeordnet ist. Durch den Einsatz des Distanzrings, welcher in axialer Richtung zwischen den Dichtringen angeordnet ist, kann der Verschleiß der Dichtringe begrenzt und somit besonders gering gehalten werden, woraus eine besonders hohe Lebensdauer des Abgasturboladers insgesamt resultiert. Im Vergleich zu herkömmlichen Abdichtanordnungen, bei welcher kein in axialer Richtung zwischen den Dichtringen angeordneter Distanzring vorgesehen ist, kann die Dauerhaltbarkeit des Abgasturboladers gesteigert werden. Mittels des Distanzrings ist es insbesondere möglich, den Verschleiß zumindest eines der Distanzringe auf ein festgelegtes Maß zu begrenzen, sodass ein übermäßiger Verschleiß vermieden werden kann.In order to further develop a sealing arrangement specified in the preamble of claim 1 such that the wear of the sealing arrangement can be kept particularly low, it is inventively provided that in the axial direction between the sealing rings at least one spacer ring is arranged. By using the spacer ring, which is arranged in the axial direction between the sealing rings, the wear of the sealing rings can be limited and thus kept very low, resulting in a particularly long service life of the exhaust gas turbocharger results overall. In comparison to conventional sealing arrangements in which no spacer ring arranged in the axial direction between the sealing rings is provided, the fatigue life of the exhaust-gas turbocharger can be increased. By means of the spacer ring, it is in particular possible to limit the wear of at least one of the spacer rings to a predetermined extent, so that excessive wear can be avoided.
