Definitions
- the present invention relates to a turbine with a turbine wheel, such as those used as a drive for active oil separators, and to a liquid separator with such a turbine.
- a separating element is often used which is rotated in order to ensure a sufficient degree of separation of a liquid from a gas, for example oil mist or oil droplets from blow-by gases of an internal combustion engine.
- Such turbines have a turbine wheel that is driven by a fluid drive means.
- oil separators in ventilation systems of internal combustion engines especially in vehicles, the oil pressure of the engine oil is often used to drive the turbine wheel.
- the utility model concerns DE2020 07009913U1 a separator for separating oil mist from the crankcase ventilation gas of an internal combustion engine of a motor vehicle, with a centrifugal rotor arranged in a gas cleaning room.
- rotors are in EP 1 782 888 A1 disclosed, such as a two-part rotor with recoil nozzles, a drive part, which is a component of the centrifuge, and a replaceable dirt trap part. But a hydraulic drive can also be used for stationary oil separators come.
- Such a turbine wheel is coupled to a shaft or mounted centrally on a shaft and drives this shaft, which in turn is coupled to a rotatable separating element.
- active oil separators common in the prior art, in which a turbine wheel is driven by means of oil pressure, the drive fluid is guided via a central bore in the shaft to the turbine wheel and introduced there into the turbine wheel.
- the turbine wheel has on its edge a nozzle directed approximately in a tangential direction, through which the fluidic drive means is ejected. This causes the turbine wheel to rotate. Speeds of up to 20,000 rpm are typical.
- turbine wheel is not limited to an approximately circular element, but also includes other forms of rotatable bodies.
- Such turbine wheels in the prior art are usually made of stainless steel. This makes the turbine wheel heavy and, in particular, complex and expensive to manufacture.
- the object of the present invention is therefore to provide a turbine wheel and a liquid separator that can be produced cost-effectively, with a stable outer contour and precisely and that are low in weight.
- the complexity of production should be reduced, the integration potential increased and the assembly of the turbine according to the invention simplified.
- a liquid separator should be made available which has such a turbine according to the invention.
- the turbine now has a turbine wheel which has a first channel running along the axis of rotation of the turbine wheel.
- This first channel can either serve as a central receptacle for a shaft, so that the shaft can be attached to the turbine wheel, or can run as an extension of the receptacle of such a shaft.
- the turbine can be sprayed onto a shaft, usually at least in sections is made of steel.
- a bearing for the shaft can also be provided in this area.
- the turbine wheel according to the invention further has a second channel running essentially in the radial direction for guiding the fluidic drive means, for example engine oil, with an inlet and an outlet for the fluidic drive means.
- the inlet is in fluid connection with the first channel.
- the outlet is essentially directed in a tangential direction of the turbine wheel.
- the exit direction has an angle of 85 to 95° to the direction of the first channel, i.e. has a small vector component in the axial direction of the shaft. This is particularly true at very high speeds.
- the turbine wheel according to the invention has exactly one second channel, since the entire drive fluid is therefore available to the outlet of this second channel.
- the turbine according to the invention also has a fluid nozzle in the outlet. Instead of a single fluid nozzle, however, several fluid nozzles can also be arranged next to one another, all of which essentially have the same outlet direction. Regardless of the exact number of nozzles, the result is a fluid flow that is at most symmetrical with respect to a cross section through the central plane of the turbine, but is otherwise asymmetrically designed.
- a metal and/or ceramic reinforcement is arranged in at least a section of a wall of the first and/or second channel.
- This turbine according to the invention with the turbine wheel according to the invention shows a simple and cost-effective design. Because only that To manufacture the turbine wheel with its two channels and to integrate the metal reinforcement, the number of individual parts required to manufacture the turbine wheel is very small. Because the turbine wheel can in particular either be shrunk onto the shaft, molded directly onto the shaft or the shaft can be embedded in the turbine wheel, depending on whether the first channel has a metal reinforcement or not, the assembly time is shortened, which also means that the assembly costs are reduced.
- the inlet of the second channel can, for example, be provided adjacent to the shaft in the passage of the shaft through the turbine wheel, so that the drive fluid is guided via a central bore of the shaft into the passage area and from there via a side bore in the shaft and the inlet according to the invention can be introduced into the turbine wheel.
- the second channel is preferably curved or angled.
- the outlet is preferably arranged on the peripheral edge of the turbine wheel.
- the fluid nozzle arranged in the outlet can be formed in one piece with the second channel, so that the turbine wheel contains the fluid nozzle as an integral component.
- the fluid nozzle can be inserted into the second channel as a separate component in the area of the outlet, for example screwed in, embedded or injected, and can contain or consist of a metal and/or a ceramic.
- this fluid nozzle can be inserted into the outlet and secured with a captive device. For example, swords or sliders inserted transversely to the longitudinal direction of the channel can be used as protection against loss.
- the outlet can be designed conically.
- the fluid nozzle can be arranged in the outlet in such a way that an exit direction of the fluidic drive means from the fluid nozzle runs essentially perpendicular to the first and/or second channel.
- the fluid nozzle can contain or consist of a metal, a ceramic or a high-quality plastic.
- the wall of the first channel and/or the second channel has a complete metal reinforcement.
- the metal reinforcement forms the inner wall of at least one channel or the nozzle. This enables particularly simple production. In addition, there is less abrasion on a metal interior wall than on a plastic interior wall.
- the metal reinforcement of the first and/or second channel is designed as a metal tube which is at least partially surrounded, in particular encapsulated, by a plastic.
- the metal reinforcement in the first channel has a recess in a connection area with the second channel, into which the metal reinforcement for the second channel is inserted and / or in which the metal reinforcement for the second channel is welded, soldered or soldered to the metal reinforcement in the first channel, in particular in a media-tight manner is crimped.
- the metal reinforcements or the metal pipes for the first and second channels can also be welded, soldered, crimped together in a media-tight manner before the turbine wheel is manufactured or, if necessary, inserted into one another with the aid of O-rings or similar sealing elements. The turbine wheel can then subsequently be sprayed onto the connected metal reinforcements or metal pipes.
- the metal reinforcements or metal tubes can initially simply be aligned and fixed to one another and then embedded together in the material of the turbine wheel, such as plastic.
- the first and second channels can extend essentially in a straight line. This is particularly advantageous when producing the turbine wheel using injection molding, injection compression and/or pressing processes.
- a large number of additional functions can easily be integrated into the turbine wheel according to the invention.
- This nozzle can be manufactured in one piece with the turbine wheel, in particular injected in one piece.
- a socket on the top and/or bottom of the turbine wheel which enables the rotating components to be mounted or which accommodates and/or guides the shaft at least in sections. It is particularly advantageous here if a partition wall, in particular a partition wall manufactured integrally with the turbine, is provided between the shaft and the first channel of the turbine, so that no drive oil can reach the shaft. If such a partition is provided, the first channel is then not designed to accommodate the shaft, but rather runs in an extension of the shaft. The drive oil is fed through a line section in the connector to the first channel and further to the second channel.
- the turbine wheel can be manufactured in lightweight construction.
- the turbine wheel and/or its housing can be made predominantly or entirely of plastic.
- Thermoplastics include polyphenylene sulfide (PPS), polyetherimide (PEI), polyimides (PI), polyphthalamides (PPA), polyetheretherketone (PEEK), polyamide (PA), polypropylene (PP), polyamideimide (PAI), polysulfone (PSU) and/or or liquid crystal polymer (LCP) or combinations of the aforementioned materials are particularly advantageous.
- PPS polyphenylene sulfide
- PEI polyetherimide
- PI polyphthalamides
- PEEK polyetheretherketone
- PA polyamide
- PA polypropylene
- PAI polyamideimide
- PSU polysulfone
- LCP liquid crystal polymer
- Thermoset plastics such as polyester resins (UP), vinyl ester resins (VE), epoxy resins (EP), phenolic resins (PF), melamine-formaldehyde resins (MF) can also be used.
- UP polyester resins
- VE vinyl ester resins
- EP epoxy resins
- PF phenolic resins
- MF melamine-formaldehyde resins
- Such a turbine wheel can be manufactured particularly easily, for example by means of injection molding, injection compression or a pressing process. If the turbine wheel is made from a thermoset material, this can also be done using transfer molding be accomplished.
- production from metals preferably light metals, for example aluminum, is also possible.
- sintered material can be processed using 3D printing.
- the second channel in such a way that it passes from one peripheral edge to the other peripheral edge of the turbine wheel and thus has two opposite openings on the peripheral edge of the turbine wheel.
- the opening on one side of the channel that is not required for fluid flow can then be closed with a closure means.
- Suitable closure means include, for example, plugs that can be pressed into the opening and secured with a sword or a slider. It is advantageous if the sword or the slide is inserted from or through the top or bottom of the turbine and is guided at least in sections in a groove laterally and/or in the wall opposite the insertion side.
- Such a sword or such a slide can also be part of another component adjacent to the turbine or be designed as an integral extension of one.
- the plug is possible; this can, if necessary, be combined with other welding processes to produce the turbine.
- a screw cap, a bayonet cap or a ball inserted in a press fit can also be used to close an opening in the channel.
- This closure should advantageously be fluid-tight so that a closed fluid path is provided from the inlet to the outlet.
- the closure means can be combined with a suitable sealant, such as an O-ring or a liquid sealant.
- the turbine wheel is made of plastic, various advantageous configurations of the turbine wheel can be realized.
- the turbine wheel can be formed from several parts, in particular from two half-shells.
- the half or partial shells can either be two halves of the turbine wheel over 180° of the peripheral edge of the turbine wheel or the top and bottom of a turbine wheel.
- the two half-shells do not have to be identical or mirror-inverted to each other.
- It can also be partial shells that have different weight or volume proportions to the whole Make up the turbine wheel, so it may only be a partial shell, although it is advantageous if only two partial shells are connected to form a turbine wheel.
- one half-shell is just a flat lid that closes an opening in the other half-shell.
- a seal for example a molded rubber seal and/or an O-ring, can advantageously be arranged between the individual parts, in particular between the two half-shells of the turbine wheel. This is pressed between the two parts, for example by screwing, welding, clipping, gluing or otherwise connecting the two half-shells together, for example analogous to a bayonet lock.
- the turbine wheel can also have a housing within which, among other things, the channels (or their walls) and further stiffening structures, for example stiffening webs or stiffening ribs, can be arranged.
- the housing can be formed in one piece with the turbine wheel. It is also possible to do without the housing and to produce the turbine wheel exclusively from the walls of the channels and, if necessary, such stiffening structures.
- the outer walls of the channels, the stiffening structures and the housing all serve, among other things, to stiffen the turbine wheel, to adjust the correct weight distribution (balancing the turbine wheel) and, for example, to guide the oil. Housings, stiffening structures and channels or their walls can therefore be designed differently depending on the design in terms of their position, thickness and shape and the like.
- the design of the stiffening webs or the stiffening ribs can serve the design with regard to noise, vibrations and heat distribution (NVH, i.e. noise vibration harshness optimization).
- NVH noise vibration harshness optimization
- a rib structure promotes the agglomeration and drainage of oil, especially spray oil.
- the housing can also be designed as a half-shell, for example as a base or cover (bottom part and also as an upper part) of the turbine wheel.
- the housing can advantageously have a smooth and/or closed surface. It is also possible to apply functional components to a surface of the turbine wheel, for example an impeller for generating negative pressure and/or a sealing element.
- further functional elements such as a magnet
- a magnet can be embedded in the turbine wheel.
- the speed of the turbine wheel can be detected.
- a plain bearing can be cast into the turbine wheel, so that the turbine wheel can be stored together or separately from the shaft in an oil separator with low friction.
- the use of plastic also makes it possible to spray the turbine wheel directly onto the shaft, for example to spray it onto a steel shaft in a media-tight manner. Additionally or alternatively, sealing using additional sealing elements such as O-rings is possible.
- FIG. 1 shows a vertical section through a liquid separator according to the invention 1.
- the liquid separator 1 has a housing 4, which is divided into a drive chamber 7 and a separation chamber 5.
- Drive chamber 7 and separation chamber 5 are separated from each other by a partition 6.
- a plate separator 2 is arranged in the separation chamber 5 and has a large number of plates 3 stacked one above the other as separating elements.
- the plate separator 2 is attached to a shaft 8 in its axis of rotation.
- the shaft 8 extends through an opening in the partition 6 into the drive chamber 7.
- the shaft 8 is rotatably mounted on a bearing 9.
- a turbine 10 is also attached to the shaft 8 in the drive chamber 7.
- the turbine 10 drives the disc separator 2 using a driving fluid such as engine oil.
- liquid separator 1 When the liquid separator 1 is operated as an oil separator in an internal combustion engine, engine oil flows as a drive fluid through a central bore 8b inside the shaft 8.
- the arrow 38 indicates the supply direction of the engine oil.
- the engine oil enters the turbine 10 from the shaft 8 via a lateral bore 8a in the shaft 8, is guided to the peripheral edge of the turbine 10 due to the rotation of the turbine wheel and is directed approximately in a tangential direction Fluid nozzle 14 is ejected again. This causes the turbine wheel to rotate and thereby drives the plate separator 2, which is firmly connected to the turbine 10 via the shaft 8.
- FIG. 2 shows a horizontal section through a turbine 10 according to a first exemplary embodiment.

Description
Die vorliegende Erfindung betrifft eine Turbine mit einem Turbinenrad, wie sie beispielsweise als Antrieb für aktive Ölabscheider verwendet werden, sowie einen Flüssigkeitsabscheider mit einer derartigen Turbine.The present invention relates to a turbine with a turbine wheel, such as those used as a drive for active oil separators, and to a liquid separator with such a turbine.
In derartigen aktiven Ölabscheidern wird oftmals ein Abscheideelement verwendet, das in Drehung versetzt wird, um einen ausreichenden Abscheidegrad einer Flüssigkeit aus einem Gas, beispielsweise von Ölnebel oder Öltröpfchen aus Blow-By-Gasen eines Verbrennungsmotors zu gewährleisten.In such active oil separators, a separating element is often used which is rotated in order to ensure a sufficient degree of separation of a liquid from a gas, for example oil mist or oil droplets from blow-by gases of an internal combustion engine.
Derartige Turbinen weisen ein Turbinenrad auf, das mit einem fluidischen Antriebsmittel angetrieben wird. Bei Ölabscheidern in Entlüftungssystemen von Verbrennungsmotoren, insbesondere bei Fahrzeugen, wird für den Antrieb des Turbinenrades oftmals der Öldruck des Motoröls verwendet. Beispielsweise betrifft das Gebrauchsmuster
Andere Rotoren sind in
Ein derartiges Turbinenrad ist mit einer Welle gekoppelt bzw. zentral auf einer Welle gelagert und treibt diese Welle an, die ihrerseits mit einem drehbaren Abscheideelement gekoppelt ist. Bei im Stand der Technik üblichen aktiven Ölabscheidern, bei denen mittels des Öldrucks ein Turbinenrad angetrieben wird, wird das Antriebsfluid über eine Mittelbohrung in der Welle bis zum Turbinenrad geführt und dort in das Turbinenrad eingeleitet. Das Turbinenrad weist an seinem Rand eine ungefähr in tangentialer Richtung gerichtete Düse auf, über die das fluidische Antriebsmittel ausgestoßen wird. Dadurch wird das Turbinenrad in Drehung versetzt. Typisch sind dabei Drehzahlen bis zu 20.000 rpm.Such a turbine wheel is coupled to a shaft or mounted centrally on a shaft and drives this shaft, which in turn is coupled to a rotatable separating element. In active oil separators common in the prior art, in which a turbine wheel is driven by means of oil pressure, the drive fluid is guided via a central bore in the shaft to the turbine wheel and introduced there into the turbine wheel. The turbine wheel has on its edge a nozzle directed approximately in a tangential direction, through which the fluidic drive means is ejected. This causes the turbine wheel to rotate. Speeds of up to 20,000 rpm are typical.
Der Begriff Turbinenrad ist dabei nicht auf ein näherungsweise kreisrundes Element beschränkt, sondern umfasst auch andere Formen rotationsfähiger Körper.The term turbine wheel is not limited to an approximately circular element, but also includes other forms of rotatable bodies.
Derartige Turbinenräder im Stand der Technik sind üblicherweise aus Edelstahl gefertigt. Dies macht das Turbinenrad schwer und insbesondere aufwändig und teuer in der Herstellung.Such turbine wheels in the prior art are usually made of stainless steel. This makes the turbine wheel heavy and, in particular, complex and expensive to manufacture.
Aufgabe der vorliegenden Erfindung ist es daher, ein Turbinenrad sowie einen Flüssigkeitsabscheider zur Verfügung zu stellen, die kostengünstig, mit stabiler Außenkontur und präzise hergestellt werden können und ein geringes Gewicht aufweisen. Insbesondere soll die Komplexität der Herstellung verringert, das Integrationspotential erhöht und die Montage der erfindungsgemäßen Turbine vereinfacht werden. Weiterhin soll ein Flüssigkeitsabscheider zur Verfügung gestellt werden, der eine derartige erfindungsgemäße Turbine aufweist.The object of the present invention is therefore to provide a turbine wheel and a liquid separator that can be produced cost-effectively, with a stable outer contour and precisely and that are low in weight. In particular, the complexity of production should be reduced, the integration potential increased and the assembly of the turbine according to the invention simplified. Furthermore, a liquid separator should be made available which has such a turbine according to the invention.
Erfindungsgemäß weist die Turbine nun ein Turbinenrad auf, das einen längs der Drehachse des Turbinenrads verlaufenden ersten Kanal aufweist. Dieser erste Kanal kann entweder als zentrale Aufnahme einer Welle, so dass die Welle an dem Turbinenrad befestigt werden kann, dienen oder in Verlängerung der Aufnahme einer solchen Welle verlaufen. Beispielsweise kann die Turbine auf eine Welle aufgespritzt werden, die üblicherweise zumindest abschnittsweise aus Stahl besteht. In einer anderen Variante ist es auch möglich, die Turbine mit einer Aufnahmegeometrie für eine metallische Welle zu versehen. Ebenso ist es möglich, die Welle in das Turbinenrad einzubetten, beispielsweise warm einzubetten. Zusätzlich kann in diesem Bereich auch ein Lager für die Welle vorgesehen sein.According to the invention, the turbine now has a turbine wheel which has a first channel running along the axis of rotation of the turbine wheel. This first channel can either serve as a central receptacle for a shaft, so that the shaft can be attached to the turbine wheel, or can run as an extension of the receptacle of such a shaft. For example, the turbine can be sprayed onto a shaft, usually at least in sections is made of steel. In another variant, it is also possible to provide the turbine with a receiving geometry for a metallic shaft. It is also possible to embed the shaft in the turbine wheel, for example to embed it warm. In addition, a bearing for the shaft can also be provided in this area.
Das erfindungsgemäße Turbinenrad weist weiterhin einen im Wesentlichen in radialer Richtung verlaufenden zweiten Kanal zum Führen des fluidischen Antriebsmittels, beispielsweise Motoröl, mit einem Einlass und einem Auslass für das fluidische Antriebsmittel auf. Der Einlass steht dabei in fluidischer Verbindung mit dem ersten Kanal. Der Auslass ist im Wesentlichen in eine tangentiale Richtung des Turbinenrads gerichtet. In Einzelfällen kann es jedoch vorteilhaft sein, wenn die Austrittsrichtung einen Winkel von 85 bis 95° zur Richtung des ersten Kanals aufweist, d.h. einen geringen Vektoranteil in Achsrichtung der Welle aufweist. Dies gilt insbesondere bei sehr hohen Drehzahlen.The turbine wheel according to the invention further has a second channel running essentially in the radial direction for guiding the fluidic drive means, for example engine oil, with an inlet and an outlet for the fluidic drive means. The inlet is in fluid connection with the first channel. The outlet is essentially directed in a tangential direction of the turbine wheel. In individual cases, however, it can be advantageous if the exit direction has an angle of 85 to 95° to the direction of the first channel, i.e. has a small vector component in the axial direction of the shaft. This is particularly true at very high speeds.
Die Verwendung von metallischen oder keramischen Einsatzelementen ermöglichen zumindest, dass an den entscheidenden Stellen die Bauteile hochpräzise und äußerst formstabil sind.The use of metallic or ceramic insert elements at least enables the components to be highly precise and extremely dimensionally stable at the crucial points.
Es ist besonders vorteilhaft, wenn das erfindungsgemäße Turbinenrad genau einen zweiten Kanal aufweist, da somit das gesamte Antriebsfluid dem Auslass dieses einen zweiten Kanals zur Verfügung steht.It is particularly advantageous if the turbine wheel according to the invention has exactly one second channel, since the entire drive fluid is therefore available to the outlet of this second channel.
Die erfindungsgemäße Turbine weist weiterhin im Auslass eine Fluiddüse auf. Anstelle einer einzigen Fluiddüse können aber auch mehrere Fluiddüsen nebeneinander angeordnet sein, die alle im Wesentlichen dieselbe Auslassrichtung aufweisen. Unabhängig von der genauen Anzahl Düsen ergibt sich eine Fluidführung, die allenfalls bezüglich eines Querschnitts durch die Mittelebene der Turbine symmetrisch, sonst aber unsymmetrisch ausgeführt ist.The turbine according to the invention also has a fluid nozzle in the outlet. Instead of a single fluid nozzle, however, several fluid nozzles can also be arranged next to one another, all of which essentially have the same outlet direction. Regardless of the exact number of nozzles, the result is a fluid flow that is at most symmetrical with respect to a cross section through the central plane of the turbine, but is otherwise asymmetrically designed.
Zusätzlich ist in mindestens einem Abschnitt einer Wand des ersten und/oder zweiten Kanals eine Metall- und/oder Keramikverstärkung angeordnet.In addition, a metal and/or ceramic reinforcement is arranged in at least a section of a wall of the first and/or second channel.
Diese erfindungsgemäße Turbine mit dem erfindungsgemäßen Turbinenrad zeigt ein einfaches und kostengünstiges Design. Dadurch, dass lediglich das Turbinenrad mit seinen zwei Kanälen zu fertigen und die Metallverstärkung zu integrieren ist, ist die Teilezahl der zur Herstellung des Turbinenrades erforderlichen Einzelteile sehr gering. Dadurch, dass das Turbinenrad insbesondere entweder auf die Welle aufgeschrumpft, direkt an die Welle angespritzt werden kann oder die Welle in das Turbinenrad eingebettet werden kann, je nachdem, ob der erste Kanal eine Metallverstärkung aufweist oder nicht, wird die Montagezeit verkürzt, wobei hierdurch auch die Montagekosten verringert werden.This turbine according to the invention with the turbine wheel according to the invention shows a simple and cost-effective design. Because only that To manufacture the turbine wheel with its two channels and to integrate the metal reinforcement, the number of individual parts required to manufacture the turbine wheel is very small. Because the turbine wheel can in particular either be shrunk onto the shaft, molded directly onto the shaft or the shaft can be embedded in the turbine wheel, depending on whether the first channel has a metal reinforcement or not, the assembly time is shortened, which also means that the assembly costs are reduced.
Der Einlass des zweiten Kanals kann beispielsweise benachbart zu der Welle in dem Durchgang der Welle durch das Turbinenrad vorgesehen sein, so dass das Antriebsfluid über eine Mittelbohrung der Welle bis in den Durchlassbereich geführt und von dort über eine seitliche Bohrung in der Welle und den erfindungsgemäßen Einlass in das Turbinenrad eingebracht werden kann.The inlet of the second channel can, for example, be provided adjacent to the shaft in the passage of the shaft through the turbine wheel, so that the drive fluid is guided via a central bore of the shaft into the passage area and from there via a side bore in the shaft and the inlet according to the invention can be introduced into the turbine wheel.
Der zweite Kanal ist vorzugsweise gekrümmt oder gewinkelt ausgeführt.The second channel is preferably curved or angled.
Der Auslass ist vorzugsweise am Umfangsrand des Turbinenrades angeordnet. Die im Auslass angeordnete Fluiddüse kann dabei einteilig mit dem zweiten Kanal ausgebildet sein, so dass das Turbinenrad die Fluiddüse als integrales Bauelement enthält. Alternativ kann die Fluiddüse als separates Bauteil im Bereich des Auslasses in den zweiten Kanal eingefügt, beispielsweise eingeschraubt, eingebettet oder eingespritzt sein und ein Metall und/oder eine Keramik enthalten oder daraus bestehen. Es ist auch möglich, diese Fluiddüse als Einsatzteil zu gestalten, die im Auslass befestigt wird. Hierzu kann diese Fluiddüse in den Auslass eingesetzt und mit einer Verliersicherung gesichert werden. Als Verliersicherung kommen hierzu beispielsweise quer zur Längsrichtung des Kanals eingesetzte Schwerter oder Schieber in Frage. Um das Einsetzen der Fluiddüse zu erleichtern kann der Auslass konisch ausgestaltet sein. Insbesondere kann die Fluiddüse derart im Auslass angeordnet sein, dass eine Austrittsrichtung des fluidischen Antriebsmittels aus der Fluiddüse im Wesentlichen senkrecht zum ersten und/oder zweiten Kanal verläuft. Die Fluiddüse kann ein Metall, eine Keramik oder einen hochwertigen Kunststoff enthalten oder daraus bestehen.The outlet is preferably arranged on the peripheral edge of the turbine wheel. The fluid nozzle arranged in the outlet can be formed in one piece with the second channel, so that the turbine wheel contains the fluid nozzle as an integral component. Alternatively, the fluid nozzle can be inserted into the second channel as a separate component in the area of the outlet, for example screwed in, embedded or injected, and can contain or consist of a metal and/or a ceramic. It is also possible to design this fluid nozzle as an insert that is attached to the outlet. For this purpose, this fluid nozzle can be inserted into the outlet and secured with a captive device. For example, swords or sliders inserted transversely to the longitudinal direction of the channel can be used as protection against loss. In order to facilitate the insertion of the fluid nozzle, the outlet can be designed conically. In particular, the fluid nozzle can be arranged in the outlet in such a way that an exit direction of the fluidic drive means from the fluid nozzle runs essentially perpendicular to the first and/or second channel. The fluid nozzle can contain or consist of a metal, a ceramic or a high-quality plastic.
Insbesondere sind bei einer ersten Variante lediglich das einstückige Turbinenrad und eine entsprechende, insbesondere metallische oder keramische Fluiddüse erforderlich.In particular, in a first variant only the one-piece turbine wheel and a corresponding fluid nozzle, in particular a metallic or ceramic one, is required.
Bei der vorliegenden Erfindung weist die Wand des ersten Kanals und/oder des zweiten Kanals vollständig eine Metallverstärkung aufweis. Insbesondere bildet die Metallverstärkung die Innenwandung mindestens eines Kanals oder der Düse. Dies ermöglicht eine besonders einfache Herstellung. Zudem tritt an einer metallischen Innenwand eine geringere Abrasion auf als an einer Kunststoff-Innenwand.In the present invention, the wall of the first channel and/or the second channel has a complete metal reinforcement. In particular, the metal reinforcement forms the inner wall of at least one channel or the nozzle. This enables particularly simple production. In addition, there is less abrasion on a metal interior wall than on a plastic interior wall.
Besonders bevorzugt ist es, wenn die Metallverstärkung des ersten und/oder zweiten Kanals als ein Metallrohr ausgebildet ist, das von einem Kunststoff zumindest abschnittsweise umgeben, insbesondere umspritzt ist.It is particularly preferred if the metal reinforcement of the first and/or second channel is designed as a metal tube which is at least partially surrounded, in particular encapsulated, by a plastic.
Weiterhin die Metallverstärkung im ersten Kanal in einem Verbindungsbereich mit dem zweiten Kanal eine Aussparung aufweist, in welche die Metallverstärkung für den zweiten Kanal eingefügt ist und/oder in welcher die Metallverstärkung für den zweiten Kanal mit der Metallverstärkung im ersten Kanal insbesondere mediendicht verschweißt, verlötet oder vercrimpt ist. Die Metallverstärkungen oder die Metallrohre für den ersten und zweiten Kanal können auch schon vor der Herstellung des Turbinenrades mediendicht miteinander verschweißt, verlötet, vercrimpt oder gegebenenfalls unter Zuhilfenahme von O-Ringen oder ähnlichen Abdichtelementen ineinander gesteckt werden. Das Turbinenrad kann dann anschließend auf die verbundenen Metallverstärkungen oder Metallrohre aufgespritzt werden. Alternativ können die Metallverstärkungen oder Metallrohre auch zunächst lediglich entsprechend zueinander ausgerichtet und fixiert werden und anschließend gemeinsam in das Material des Turbinenrades, wie z.B. Kunststoff, eingebettet werden.Furthermore, the metal reinforcement in the first channel has a recess in a connection area with the second channel, into which the metal reinforcement for the second channel is inserted and / or in which the metal reinforcement for the second channel is welded, soldered or soldered to the metal reinforcement in the first channel, in particular in a media-tight manner is crimped. The metal reinforcements or the metal pipes for the first and second channels can also be welded, soldered, crimped together in a media-tight manner before the turbine wheel is manufactured or, if necessary, inserted into one another with the aid of O-rings or similar sealing elements. The turbine wheel can then subsequently be sprayed onto the connected metal reinforcements or metal pipes. Alternatively, the metal reinforcements or metal tubes can initially simply be aligned and fixed to one another and then embedded together in the material of the turbine wheel, such as plastic.
In einem weiteren vorteilhaften Ausführungsbeispiel der Erfindung können sich der erste und der zweite Kanal, mit Ausnahme des Auslasses, im Wesentlichen geradlinig erstrecken. Dies ist insbesondere vorteilhaft bei der Herstellung des Turbinenrads im Spritzguss-, Spritzpräge- und/oder Pressverfahren.In a further advantageous embodiment of the invention, the first and second channels, with the exception of the outlet, can extend essentially in a straight line. This is particularly advantageous when producing the turbine wheel using injection molding, injection compression and/or pressing processes.
In das erfindungsgemäße Turbinenrad kann problemlos eine Vielzahl von Zusatzfunktionen integriert werden. Beispielsweise ist es möglich, auf der Oberseite des Turbinenrades einen Stutzen vorzusehen, der die Welle abschnittsweise aufnimmt, so dass eine verbesserte Halterung der Welle in dem Turbinenrad bewirkt wird. Dieser Stutzen kann einteilig mit dem Turbinenrad gefertigt, insbesondere einteilig gespritzt werden.A large number of additional functions can easily be integrated into the turbine wheel according to the invention. For example, it is possible to provide a socket on the top of the turbine wheel, which receives the shaft in sections, so that an improved retention of the shaft in the turbine wheel is achieved. This nozzle can be manufactured in one piece with the turbine wheel, in particular injected in one piece.
Ebenso ist es möglich, auf der Ober- und/oder Unterseite des Turbinenrades einen Stutzen vorzusehen, der die Lagerung der rotierenden Bauteile ermöglicht oder die Welle zumindest abschnittsweise aufnimmt und/oder führt. Hierbei ist es besonders vorteilhaft, wenn zwischen der Welle und dem ersten Kanal der Turbine eine Trennwand, insbesondere eine integral mit der Turbine gefertigte Trennwand vorgesehen ist, so dass kein Antriebsöl zur Welle gelangen kann. Ist eine solche Trennwand vorgesehen, ist der erste Kanal dann insbesondere nicht zur Aufnahme der Welle ausgebildet, sondern verläuft in Verlängerung der Welle. Das Antriebsöl wird durch einen Leitungsabschnitt in dem Stutzen dem ersten Kanal und weiter dem zweiten Kanal zugeführt.It is also possible to provide a socket on the top and/or bottom of the turbine wheel, which enables the rotating components to be mounted or which accommodates and/or guides the shaft at least in sections. It is particularly advantageous here if a partition wall, in particular a partition wall manufactured integrally with the turbine, is provided between the shaft and the first channel of the turbine, so that no drive oil can reach the shaft. If such a partition is provided, the first channel is then not designed to accommodate the shaft, but rather runs in an extension of the shaft. The drive oil is fed through a line section in the connector to the first channel and further to the second channel.
Insbesondere ist es vorteilhaft, dass das Turbinenrad im Leichtbau hergestellt werden kann. Hierzu können beispielsweise das Turbinenrad und/oder sein Gehäuse überwiegend oder vollständig aus Kunststoff bestehen. Als thermoplastische Kunststoffe kommen Polyphenylensulfid (PPS), Polyetherimid (PEI), Polyimide (PI), Polyphthalamide (PPA), Polyetheretherketon (PEEK), Polyamid (PA), Polypropylen (PP), Polyamidimid (PAI), Polysulfon (PSU) und/oder Liquid-Crystal Polymer (LCP) oder Kombinationen der vorgenannten Materialien besonders vorteilhaft in Frage. Sie können weiterhin mittels Fasern, wie Aramidfasern, Kohlefasern oder Glasfasern und/oder sonstigen Füllstoffen, beispielsweise partikulären Füllstoffen, wie etwa Glaskugeln oder Partikeln auf Mineralbasis verstärkt sein. Als Füllstoffe kommen insbesondere Calciumcarbonat, Calciumsulfat, Kaolin, Glimmer, Talkum und Quarz in Betracht. Ebenso können duroplastische Kunststoffe, wie Polyesterharze (UP), Vinylesterharze (VE), Epoxidharze (EP), Phenolharze (PF), MelaminFormaldehyd-Harze (MF) eingesetzt werden. Ein derartiges Turbinenrad kann besonders einfach hergestellt werden, beispielsweise mittels Spritzguss, Spritzpräge- oder in einem Pressverfahren. Wird das Turbinenrad aus einem duroplastischen Werkstoff hergestellt, kann dies auch mittels Spritzpressen bewerkstelligt werden. Weiterhin ist auch eine Herstellung aus Metallen, vorzugsweise Leichtmetallen, beispielsweise aus Aluminium möglich, Hierzu kann beispielsweise Sintermaterial mittels 3-D-Druck verarbeitet werden.It is particularly advantageous that the turbine wheel can be manufactured in lightweight construction. For this purpose, for example, the turbine wheel and/or its housing can be made predominantly or entirely of plastic. Thermoplastics include polyphenylene sulfide (PPS), polyetherimide (PEI), polyimides (PI), polyphthalamides (PPA), polyetheretherketone (PEEK), polyamide (PA), polypropylene (PP), polyamideimide (PAI), polysulfone (PSU) and/or or liquid crystal polymer (LCP) or combinations of the aforementioned materials are particularly advantageous. They can also be reinforced using fibers such as aramid fibers, carbon fibers or glass fibers and/or other fillers, for example particulate fillers such as glass beads or mineral-based particles. Calcium carbonate, calcium sulfate, kaolin, mica, talc and quartz are particularly suitable as fillers. Thermoset plastics such as polyester resins (UP), vinyl ester resins (VE), epoxy resins (EP), phenolic resins (PF), melamine-formaldehyde resins (MF) can also be used. Such a turbine wheel can be manufactured particularly easily, for example by means of injection molding, injection compression or a pressing process. If the turbine wheel is made from a thermoset material, this can also be done using transfer molding be accomplished. Furthermore, production from metals, preferably light metals, for example aluminum, is also possible. For this purpose, for example, sintered material can be processed using 3D printing.
Zur einfachen Gestaltung des Werkzeuges bietet sich an, den zweiten Kanal derart vorzusehen, dass dieser vom einen Umfangsrand zum anderen Umfangsrand des Turbinenrades durchgeht und so am Umfangsrand des Turbinenrades zwei gegenüberliegende Öffnungen aufweist. Die für die Fluidführung nicht benötigte Öffnung auf einer Seite des Kanals kann dann mit einem Verschlussmittel verschlossen werden. Als Verschlussmittel eignen sich beispielsweise Stopfen, die in der Öffnung verpresst, mit einem Schwert oder einem Schieber gesichert werden können. Es ist dabei vorteilhaft, wenn das Schwert oder der Schieber von der bzw. durch die Ober- oder Unterseite der Turbine eingeführt und seitlich und/oder in der der Einführungsseite gegenüberliegenden Wandung zumindest abschnittsweise in einer Nut geführt wird. Ein solches Schwert oder ein solcher Schieber kann auch Teil eines anderen zur Turbine benachbarten Bauteils oder als integraler Fortsatz eines solchen ausgebildet sein. Alternativ ist ein Verschweißen des Stopfens möglich, dies kann ggf. mit anderen Schweißvorgängen zur Herstellung der Turbine kombiniert werden. Auch ein Schraubverschluss, ein Bajonettverschluss oder eine im Presssitz eingebrachte Kugel kann zum Verschluss einer Öffnung des Kanals dienen. Dieser Verschluss sollte vorteilhafterweise fluiddicht sein, so dass ein geschlossener Fluidweg vom Einlass zum Auslass zur Verfügung gestellt wird. Hierzu kann das Verschlussmittel mit einem geeigneten Abdichtmittel kombiniert werden, etwa mit einem O-Ring oder einem Flüssigdichtmittel.For a simple design of the tool, it is advisable to provide the second channel in such a way that it passes from one peripheral edge to the other peripheral edge of the turbine wheel and thus has two opposite openings on the peripheral edge of the turbine wheel. The opening on one side of the channel that is not required for fluid flow can then be closed with a closure means. Suitable closure means include, for example, plugs that can be pressed into the opening and secured with a sword or a slider. It is advantageous if the sword or the slide is inserted from or through the top or bottom of the turbine and is guided at least in sections in a groove laterally and/or in the wall opposite the insertion side. Such a sword or such a slide can also be part of another component adjacent to the turbine or be designed as an integral extension of one. Alternatively, welding the plug is possible; this can, if necessary, be combined with other welding processes to produce the turbine. A screw cap, a bayonet cap or a ball inserted in a press fit can also be used to close an opening in the channel. This closure should advantageously be fluid-tight so that a closed fluid path is provided from the inlet to the outlet. For this purpose, the closure means can be combined with a suitable sealant, such as an O-ring or a liquid sealant.
Wenn das Turbinenrad aus Kunststoff hergestellt ist, können verschiedene vorteilhafte Ausgestaltungen des Turbinenrades realisiert werden.If the turbine wheel is made of plastic, various advantageous configurations of the turbine wheel can be realized.
So kann das Turbinenrad beispielsweise aus mehreren Teilen, insbesondere aus zwei Halbschalen, ausgebildet werden. Die Halb- oder Teilschalen können entweder zwei Hälften des Turbinenrades über jeweils 180° des Umfangsrandes des Turbinenrades oder auch die Oberseite und die Unterseite eines Turbinenrades sein. Die beiden Halbschalen müssen keinesfalls baugleich oder spiegelverkehrt zueinander gefertigt sein. Es kann sich auch um Teilschalen handeln, die unterschiedliche Gewichts- bzw. Volumenanteile am gesamten Turbinenrad ausmachen, es handelt sich also ggf. nur um eine Teilschale, wobei es vorteilhaft ist, wenn lediglich zwei Teilschalen zu einem Turbinenrad verbunden werden. Im Extremfall handelt es sich bei einer Halbschale nur um einen flächigen Deckel, der eine Öffnung in der anderen Halbschale verschließt. Zwischen den einzelnen Teilen, insbesondere zwischen den beiden Halbschalen des Turbinenrades kann vorteilhafterweise eine Dichtung, beispielsweise eine Gummiformdichtung und/oder ein O-Ring angeordnet werden. Diese wird zwischen den beiden Teilen verpresst, indem beispielsweise die zwei Halbschalen miteinander verschraubt, verschweißt, verclipst, verklebt oder anderweitig verbunden werden, beispielsweise analog zu einem Bajonett-Verschluss.For example, the turbine wheel can be formed from several parts, in particular from two half-shells. The half or partial shells can either be two halves of the turbine wheel over 180° of the peripheral edge of the turbine wheel or the top and bottom of a turbine wheel. The two half-shells do not have to be identical or mirror-inverted to each other. It can also be partial shells that have different weight or volume proportions to the whole Make up the turbine wheel, so it may only be a partial shell, although it is advantageous if only two partial shells are connected to form a turbine wheel. In extreme cases, one half-shell is just a flat lid that closes an opening in the other half-shell. A seal, for example a molded rubber seal and/or an O-ring, can advantageously be arranged between the individual parts, in particular between the two half-shells of the turbine wheel. This is pressed between the two parts, for example by screwing, welding, clipping, gluing or otherwise connecting the two half-shells together, for example analogous to a bayonet lock.
Das Turbinenrad kann weiterhin ein Gehäuse aufweisen, innerhalb dessen unter anderem die Kanäle (bzw. deren Wände) und weitere Versteifungsstrukturen, beispielsweise Versteifungsstege oder Aussteifungsrippen angeordnet sein können. Das Gehäuse kann dabei einteilig mit dem Turbinenrad ausgebildet sein. Es ist auch möglich, auf das Gehäuse zu verzichten und das Turbinenrad ausschließlich aus den Wänden der Kanäle und ggf. derartigen Versteifungsstrukturen herzustellen. Die Außenwände der Kanäle, die Versteifungsstrukturen als auch das Gehäuse dienen sämtlich unter anderem auch der Versteifung des Turbinenrades, der Einstellung der richtigen Gewichtsverteilung (Auswuchten des Turbinenrades) und beispielsweise auch der Ölführung. Gehäuse, Versteifungsstrukturen und Kanäle bzw. deren Wände können folglich je nach Auslegung unterschiedlich bezüglich ihrer Lage, ihrer Dicke und Form und dergleichen ausgelegt werden. Insbesondere kann die Ausgestaltung der Versteifungsstege oder der Aussteifungsrippen dem Design bezüglich Geräuschen, Schwingungen und Wärmeverteilung dienen (NVH, d.h. Noise Vibration Harshness-Optimierung). Zudem begünstigt eine Rippenstruktur das Agglomerieren und Ablaufen von Öl, insbesondere von Spritzöl.The turbine wheel can also have a housing within which, among other things, the channels (or their walls) and further stiffening structures, for example stiffening webs or stiffening ribs, can be arranged. The housing can be formed in one piece with the turbine wheel. It is also possible to do without the housing and to produce the turbine wheel exclusively from the walls of the channels and, if necessary, such stiffening structures. The outer walls of the channels, the stiffening structures and the housing all serve, among other things, to stiffen the turbine wheel, to adjust the correct weight distribution (balancing the turbine wheel) and, for example, to guide the oil. Housings, stiffening structures and channels or their walls can therefore be designed differently depending on the design in terms of their position, thickness and shape and the like. In particular, the design of the stiffening webs or the stiffening ribs can serve the design with regard to noise, vibrations and heat distribution (NVH, i.e. noise vibration harshness optimization). In addition, a rib structure promotes the agglomeration and drainage of oil, especially spray oil.
Das Gehäuse kann jedoch auch als Halbschale ausgebildet werden, beispielsweise als Boden oder auch Deckel (Unterteil und auch als Oberteil) des Turbinenrades. Das Gehäuse kann dabei vorteilhafterweise eine glatte und/oder geschlossene Oberfläche aufweisen. Ebenso ist es möglich, auf einer Oberfläche des Turbinenrades Funktionsbauteile aufzubringen, beispielsweise ein Flügelrad zur Unterdruckerzeugung und/oder ein Dichtelement.However, the housing can also be designed as a half-shell, for example as a base or cover (bottom part and also as an upper part) of the turbine wheel. The housing can advantageously have a smooth and/or closed surface. It is also possible to apply functional components to a surface of the turbine wheel, for example an impeller for generating negative pressure and/or a sealing element.
Insbesondere bei Verwendung eines Turbinenrades aus Kunststoff oder im Wesentlichen aus Kunststoff können weitere Funktionselemente, wie beispielsweise ein Magnet in das Turbinenrad eingebettet werden. Mittels eines derartigen eingebetteten Magnetes kann beispielsweise die Drehzahl des Turbinenrades erfasst werden. Weiterhin kann in das Turbinenrad ein Gleitlager eingegossen werden, so dass das Turbinenrad gemeinsam oder auch getrennt von der Welle reibungsarm in einem Ölabscheider gelagert werden kann. Die Verwendung von Kunststoff ermöglicht es auch, das Turbinenrad unmittelbar auf der Welle anzuspritzen, beispielsweise mediendicht auf einer Stahlwelle anzuspritzen. Zusätzlich oder alternativ ist eine Abdichtung mittels zusätzlicher Dichtelementen wie z.B. O-Ringen möglich.Particularly when using a turbine wheel made of plastic or essentially made of plastic, further functional elements, such as a magnet, can be embedded in the turbine wheel. Using such an embedded magnet, for example, the speed of the turbine wheel can be detected. Furthermore, a plain bearing can be cast into the turbine wheel, so that the turbine wheel can be stored together or separately from the shaft in an oil separator with low friction. The use of plastic also makes it possible to spray the turbine wheel directly onto the shaft, for example to spray it onto a steel shaft in a media-tight manner. Additionally or alternatively, sealing using additional sealing elements such as O-rings is possible.
