Die Erfindung bezieht sich auf einen Halteflansch für eine elektrische Maschine, insbesondere für einen Starter einer Verbrennungskraftmaschine, zur Befestigung der elektrischen Maschine mit einem Lagerschild an derThe invention relates to a retaining flange for an electrical machine, in particular for a starter of an internal combustion engine, for fastening the electric machine with a bearing plate on the

Verbrennungskraftmaschine, wobei der Halteflansch eine zentrierte Kreisöffnung aufweist. Die Erfindung bezieht sich ferner auf eine elektrische Maschine, insbesondere Starter für eine Verbrennungskraftmaschine, mit einem Gehäuse und einem Lagerschild, an dem ein Zwischenflansch ausgebildet ist, auf den ein Halteflansch zur Befestigung mit der Verbrennungskraftmaschine montiert ist, wobei der Halteflansch Befestigungsbohrungen zur Befestigung an einem Zwischenflansch des Lagerschilds und Befestigungslöcher zur Befestigung an der Verbrennungskraftmaschine aufweist.Internal combustion engine, wherein the retaining flange has a centered circular opening. The invention further relates to an electrical machine, in particular starter for an internal combustion engine, with a housing and a bearing plate on which an intermediate flange is formed, on which a retaining flange for attachment to the internal combustion engine is mounted, wherein the retaining flange mounting holes for attachment to a Has intermediate flange of the bearing plate and mounting holes for attachment to the internal combustion engine.

Es ist bekannt, um die spezifischen geometrischen Anforderungen, die zwischen einem Ritzel eines Starters und einem Zahnkranz von einer Verbrennungskraftmaschine auftreten, mittels eines Halteflansches anzupassen und auszugleichen. Somit kann ein standardisierter Starter mit einem standardisierten Lagerschild an verschiedenste Typen von Verbrennungsmotoren mit unterschiedlichen geometrischen Anforderungen verbaut werden. Um den Starter, der zur Ritzelwelle einen nicht gleichmäßig verteilten Außenumfang aufgrund eines Einspurrelais aufweist, in eine passende Einbauposition zu drehen, ist der Starter mittels eines sogenannten Drehflansches am Verbrennungsmotor einbaubar.It is known to adapt and balance the specific geometric requirements that occur between a pinion of a starter and a ring gear of an internal combustion engine by means of a retaining flange. Thus, a standardized starter with a standardized bearing plate can be installed on various types of internal combustion engines with different geometric requirements. In order to rotate the starter, which has a not uniformly distributed outer circumference due to a Einspurrelais, to the pinion shaft in a suitable mounting position, the starter by means of a so-called rotary flange on the internal combustion engine can be installed.

Beispielsweise sind aus dem Stand der Technik folgende Drehflansche bekannt:

  • Die JP S62 160774 , die JP H09 209885 und die US 5,847,471 beschreiben alle einen Starter mit einem Drehflansch zur Befestigung an einem Verbrennungsmotor.
For example, the following rotary flanges are known from the prior art:
  • The JP S62 160774 , the JP H09 209885 and the US 5,847,471 all describe a starter with a rotary flange for attachment to an internal combustion engine.

Die DE 10 2006 038 350 beschreibt einen Halteflansch für einen Starter, der als elektrisch isolierter Drehflansch ausgebildet ist. Schraubenöffnungen im Halteflansch können auch als Langlöcher ausgebildet sein. Diese sind konzentrisch zu einer Drehachse der Antriebswelle angeordnet. Somit ist der Starter um die Drehachse drehbar oder in mehreren bestimmten Positionen befestigbar.The DE 10 2006 038 350 describes a retaining flange for a starter, which is designed as an electrically insulated rotary flange. Screw openings in the retaining flange can also be designed as slots. These are arranged concentrically to a rotational axis of the drive shaft. Thus, the starter is rotatable about the axis of rotation or fastened in several specific positions.

Die US 3,509,618 beschreibt eine Vorrichtung zur Befestigung und zum Zusammenbau von Strukturbauteilen zur Verbindung mit nicht exakt ausgerichteten Aufnahmelöchern zur Befestigung. Zwei zylindrische Buchsen mit exzentrischen Löchern und Anschlagflächen zur Aufnahme und sicherem Halt eines Strukturbauteils werden in die nicht exakt ausgerichteten Aufnahmelöscher eingesetzt und die exzentrischen Löcher werden in Übereinstimmung gebracht. Mittels einer Schraube mit Mutter werden die Strukturbauteile nun durch ein ausgerichtetes Loch der Buchsen sicher befestigt.The US 3,509,618 describes a device for attachment and assembly of structural components for connection to non-precisely aligned receiving holes for attachment. Two cylindrical bushings with eccentric holes and abutment surfaces for receiving and securely supporting a structural member are inserted into the non-precisely aligned receiving extinguishers and the eccentric holes are made to coincide. By means of a screw with nut, the structural components are now securely fastened by an aligned hole in the sockets.

Es ist Aufgabe der Erfindung, einen Halteflansch und eine elektrische Maschine der eingangs genannten Art derart weiterzubilden, dass mit möglichst wenigen einfachen Standardbauteilen eine große Variabilität zur Anpassung an die geometrischen Anforderungen realisiert werden kann, die bezüglich eines Antriebsritzel einer elektrischen Maschine und einem Zahnkranz einer Verbrennungskraftmaschine bestehen.It is an object of the invention to develop a retaining flange and an electrical machine of the type mentioned in such a way that with as few simple standard components a large variability can be realized to adapt to the geometric requirements, with respect to a drive pinion of an electric machine and a ring gear of an internal combustion engine consist.

Erfindungsgemäß wird die Aufgabe durch den Gegenstand der Patentansprüche 1 und 8 gelöst. Vorteilhafte Weiterbildungen ergeben sich aus den abhängigen Ansprüchen.According to the invention the object is achieved by the subject matter of claims 1 and 8. Advantageous developments emerge from the dependent claims.

Ein Erfindungsgedanke ist, für eine Vielzahl von verschiedenen Typen von Verbrennungskraftmaschinen mit unterschiedlichen geometrischen, insbesondere radial einzustellenden Anforderungen bezüglich dem Abstand von einem Zahnkranz zum Antriebsritzel der Startermaschine mit einer justierbaren Exzentrizität die elektrische Maschine an dem Gehäuse der Verbrennungskraftmaschine auszurichten. Dabei wird Exzentrizität vor dem Zusammenbau festgelegt und montiert. Die Exzentrizität bildet somit eine Montagelehre zur definierten Einstellung des Abstandes zwischen Zahnkranz der Verbrennungskraftmaschine und dem Antriebsritzel.An inventive concept is, for a variety of different types of internal combustion engines with different geometric, in particular radially adjustable requirements with respect to the distance from a sprocket to the drive pinion of the starter machine with an adjustable eccentricity to align the electric machine to the housing of the internal combustion engine. Eccentricity is determined and assembled before assembly. The eccentricity thus forms an assembly jig for the defined adjustment of the distance between the ring gear of the internal combustion engine and the drive pinion.

Die Aufgabe wird erfindungsgemäß mit einem Halteflansch dadurch gelöst, dass der Halteflansch mit einem ringförmigen zweiten Bauteil mit einem zentrischen, kreisförmigen Loch und einer äußeren, zum Loch zentrischen Kreisumfangsfläche ausgebildet ist, wobei das zweite Bauteil in die Kreisöffnung des Halteflansches eingesetzt ist, und das zweite Bauteil, im folgenden auch Wechselexzentrizität genannt, eine nach außen ausgebildete Schulter mit einer exzentrischen Kreisumfangsfläche aufweist. Zur Montage des Halteflansches wird das zentrische Loch der Wechselexzentrizität mit einer exzentrischen Außenfläche als Schulter auf eine zylindrische zentrierte Fläche vom Lagerschild der elektrischen Maschine aufgeschoben. Um möglichst hohe Genauigkeitsanforderungen bezüglich der Exzentrizität zu erfüllen, ist das zentrische Loch zur zylindrisch zentrierten Fläche eine Passung. Das zentrische Loch kann auch als zentrische Kreisöffnung bezeichnet werden. Somit kann eine standardisierte Exzentrizität durch eine variable Einstellung für verschiedene Typen von Verbrennungskraftmaschinen und Applikationen angewendet werden. Der erfindungsgemäße Halteflansch ist dadurch ein Baukastensystem, das verhindert, dass für jede individuelle Exzentrizität eines bestimmten Typs ein neuer Halteflansch erstellt werden muss. Der Halteflansch ist ein Flanschgrundkörper, der für alle Exzentrizitäten, d.h. Beträge und Richtungen der Exzentrizität, eingesetzt werden kann.The object is achieved with a retaining flange characterized in that the retaining flange is formed with an annular second component having a central circular hole and an outer, circular center hole to the hole, wherein the second component is inserted into the circular opening of the retaining flange, and the second Component, hereinafter also referred to exchange eccentricity, having an outwardly formed shoulder with an eccentric circular peripheral surface. To mount the retaining flange, the centric hole of the eccentric eccentricity is pushed with an eccentric outer surface as a shoulder on a cylindrical centered surface of the bearing plate of the electric machine. In order to meet the highest possible accuracy requirements with respect to the eccentricity, the centric hole to the cylindrically centered surface is a fit. The centric hole can also be referred to as a centric circular opening. Thus, a standardized eccentricity can be applied by a variable setting for various types of internal combustion engines and applications. As a result, the retaining flange according to the invention is a modular system which prevents a new retaining flange having to be created for each individual eccentricity of a specific type. The retaining flange is a flange body suitable for all eccentricities, i. Amounts and directions of eccentricity, can be used.

Gemäß einer Ausführungsform ist die Wechselexzentrizität am Halteflansch kraftschlüssig gesichert. Die Wechselexzentrizität und der Halteflansch können Markierungen auf einer Stirnseite haben, damit sie richtig zueinander montiert werden. Gemäß einem alternativen Fertigungsverfahren werden der Halteflansch und die Wechselexzentrizität mittels einer Fertigungslehre definiert zusammengefügt, damit die Exzentrizität an einer definierten Stelle im Halteflansch erzeugt wird.According to one embodiment, the exchange eccentricity is secured non-positively on the retaining flange. The eccentric eccentricity and the retaining flange may have markings on one end face so that they are properly assembled to each other. According to an alternative manufacturing method, the retaining flange and the eccentricity of change are defined by means of a production gauge assembled so that the eccentricity is generated at a defined location in the retaining flange.

Gemäß einem alternativen Montageverfahren wird die Wechselexzentrizität auf der zylindrischen, zentrierten Fläche des Lagerschilds von der elektrischen Maschine zuerst definiert angepasst eingesetzt, und danach der Halteflansch am Lagerschild beispielsweise über den Zwischenflansch beispielsweise mit Schrauben befestigt. Am Halteflansch sind Langlöcher ausgebildet, die die Exzentrizität des Halteflansches gegenüber dem Lagerschild tolerieren und mittels denen der Halteflansch am Lagerschild befestigt Gemäß einer besonderen Ausführungsform ist die Wechselexzentrizität am Halteflansch durch Pressen, Aufschrumpfen oder Klemmen gesichert. Dies sind einfache schnelle schlüssige Montageverfahren, die zudem preiswert zu fertigen sind. Die gleiche kraftschlüssige Verbindung kann auch alternativ zwischen der zentrischen Kreisöffnung der Wechselexzentrizität und der zylindrischen zentrierten Fläche des Lagerschilds vorgesehen sein.According to an alternative assembly method, the exchange eccentricity is used on the cylindrical, centered surface of the bearing plate of the electric machine first defined adjusted, and then attached the retaining flange on the bearing plate, for example via the intermediate flange, for example with screws. At the retaining flange elongated holes are formed, which tolerate the eccentricity of the retaining flange relative to the bearing plate and by means of which the retaining flange attached to the bearing plate According to a particular embodiment, the exchange eccentricity is secured to the retaining flange by pressing, shrinking or clamping. These are simple quick-fitting assembly methods that are also inexpensive to manufacture are. The same non-positive connection may alternatively be provided between the central circular opening of the eccentric eccentricity and the cylindrical centered surface of the bearing plate.

Gemäß einer anderen Ausführungsform ist die Wechselexzentrizität am Halteflansch formschlüssig gesichert. Eine forrhschlüssige Verbindung schafft eine sichere definierte Befestigungsmöglichkeit.According to another embodiment, the exchange eccentricity is secured in a form-fitting manner on the retaining flange. A forrhschlüssige connection creates a secure defined mounting option.

Besonders bevorzugt ist die Wechselexzentrizität am Halteflansch durch eine Verschraubung gesichert. Eine Verschraubung hat den Vorteil, dass die Verbindung zur Demontage gelöst werden kann.Particularly preferably, the exchange eccentricity is secured to the retaining flange by a screw. A screw connection has the advantage that the connection for disassembly can be solved.

Gemäß einer die Erfindung weiterbildenden Ausführungsform ist die Wechselexzentrizität am Halteflansch stoffschlüssig gesichert. Eine stoffschlüssige Verbindung kann zu einer höheren Festigkeit der Verbindung führen.According to a further embodiment of the invention, the exchange eccentricity is secured cohesively on the retaining flange. A cohesive connection can lead to a higher strength of the connection.

Gemäß einer bevorzugten Ausführungsform ist die Wechselexzentrizität am Halteflansch durch Schweißen, Löten oder Kleben gesichert. Wie oben beschrieben, kann die stoffschlüssige oder formschlüssige Verbindung auch zwischen der Wechselexzentrizität und dem Lagerschild alternativ oder zusätzlich vorgesehen sein.According to a preferred embodiment, the exchange eccentricity is secured to the retaining flange by welding, soldering or gluing. As described above, the cohesive or positive connection can also be provided alternatively or additionally between the exchange eccentricity and the bearing plate.

Erfindungsgemäß wird die Aufgabe mit einer elektrischen Maschine dadurch gelöst, dass der Halteflansch mittels einer variabel einstellbaren Wechselexzentrizität als Montagelehre zur exzentrischen Befestigung am Gehäuse der Verbrennungskraftmaschine ausgebildet ist. Die Wechselexzentrizität, die in einem symmetrischen Halteflansch mit einer zentrischen Kreisöffnung eingesetzt ist, ist eine Montagehilfe, um den Halteflansch mit dem Lagerschild definiert exzentrisch an einer kreisförmigen zylindrischen Öffnung am Gehäuse der Verbrennungskraftmaschine zu montieren.According to the invention the object is achieved with an electric machine, characterized in that the retaining flange is formed by means of a variably adjustable exchange eccentricity as mounting jig for eccentric attachment to the housing of the internal combustion engine. The eccentric eccentricity, which is used in a symmetrical retaining flange with a central circular opening, is an assembly aid for eccentrically mounting the retaining flange with the end shield on a circular cylindrical opening on the housing of the internal combustion engine.

Gemäß einer weiter bevorzugten Ausführungsform ist der Halteflansch gemäß den oben beschriebenen Ausführungsformen ausgebildet und das zentrische, kreisförmige Loch der Wechselexzentrizität ist in eine zylindrische zentrierte Fläche des Lagerschilds eingepasst. Die zylindrische zentrierte Fläche des Lagerschilds bildet mit dem zentrischen, kreisförmigen Loch der Wechselexzentrizität eine Passung. Die exzentrische Außenfläche als Schulter an der Wechselexzentrizität führt zu einem Halteflansch, der an der zylindrischen Öffnung des Gehäuses zur radialen Einstellung des Ritzels bezüglich dem Zahnkranz exzentrisch befestigbar ist. Somit werden höchst präzise Exzentrizitäten an definierten Positionen erreicht.According to a further preferred embodiment, the retaining flange according to the embodiments described above is formed and the centric circular hole of the eccentric eccentricity is fitted in a cylindrical centered surface of the end shield. The cylindrical centered surface of the endshield forms a fit with the centric, circular hole of the eccentric eccentricity. The eccentric outer surface as a shoulder the exchange eccentricity leads to a retaining flange, which is eccentrically fastened to the cylindrical opening of the housing for radial adjustment of the pinion with respect to the ring gear. Thus, highly precise eccentricities are achieved at defined positions.

Gemäß einer die Erfindung weiterbildenden Ausführungsform ist der Halteflansch als ein am Zwischenflansch der elektrischen Maschine in mindestens zwei Lageanordnungen positionierbarer Drehflansch ausgebildet. Durch die zusätzliche Funktion des Halteflansches als Drehflansch ist es möglich, das Lagerschild an die räumlichen Verhältnisse an der Verbrennungskraftmaschine anzupassen, da das Lagerschild an einer Seite aufgrund eines Einspurrelais nicht rotationssymmetrisch gleich, sondern hervorgehoben ausgebildet ist Die elektrische Maschine kann je nach Typ der Verbrennungskraftmaschine am Halteflansch möglicherweise gedreht eingebaut werden.According to one embodiment of the invention, the retaining flange is designed as a rotary flange which can be positioned in at least two positional arrangements on the intermediate flange of the electric machine.

Weiter bevorzugt ist der Halteflansch als Isolierteil ausgebildet, zumindest teilweise aus einem elektrischen isolierenden Material hergestellt oder der Halteflansch weist ein auf dem Halteflansch angeordnetes Isolierelement auf. Somit wird, was für manche Anwendungen erforderlich ist, eine elektrische Potentialtrennung zwischen einem Gehäuse der elektrischen Maschine und der Verbrennungskraftmaschine sicher geschaffen.More preferably, the retaining flange is formed as an insulating part, at least partially made of an electrically insulating material or the retaining flange has an insulating element arranged on the retaining flange. Thus, what is required for some applications, electrical potential separation between a housing of the electric machine and the internal combustion engine safely created.

Der Halteflansch mit der Wechselexzentrizität kann zweiteilig oder mehrteilig aufgebaut sein, d.h. es können im Halteflansch auch mehrere zum Beispiel zwei Wechselexzentrizitäten mit jeweils einer exzentrischen Kreisumfangsfläche, ineinander eingesetzt sein, die eine noch größere Variabilität ermöglichen. Im zentrischen Loch einer größeren kreisförmigen ist eine kleinere kreisförmige, exzentrische Wechselexzentrizität mit einem kreisförmigen, zentrischen Loch eingesetzt. Das zentrische Loch der kleineren Wechselexzentrizität wird auf die zylindrische Fläche des Lagerschilds eingeschoben.The retaining flange with the exchange eccentricity can be constructed in two parts or in several parts, i. It can be used in each other in the retaining flange, for example, two Wechselexzentrizitäten each with an eccentric circular peripheral surface, which allow an even greater variability.

a Wechselexzentrizität in plan view and
Fig. 4
a retaining flange in the cross-sectional view.

Die Fig. 1 zeigt in einer perspektivischen Ansicht einen Halteflansch 1, der zum Teil aufgeschnitten ist. Der Halteflansch 1 ist ein symmetrisches Bauteil mit einer zentrierten Kreisöffnung 2 und Befestigungsbohrungen 3, 4. Die Befestigungsbohrungen 3, 4 dienen zur Befestigung bzw. Verschraubung des Halteflansches 1 an einem Zwischenflansch 5 am Lagerschild 6 einer nicht weiter dargestellten elektrischen Maschine, die beispielsweise ein Starter für eine Verbrennungskraftmaschine ist. Der Zwischenflansch 5 hat zur Verschraubung des Halteflansches 1 eine Vielzahl von Gewindebohrungen 7, 8, 9, die um ein paar Winkelgrade zu einander versetzt ausgebildet sind. Die Vielzahl von Gewindebohrungen 7, 8 und 9 sind vorgesehen, um den Halteflansch 1 als Drehflansch einzusetzen und damit den Starter entsprechend den räumlichen Gegebenheiten gedreht einzubauen, da der Starter nicht eine rotationssymmetrische, sondern auf der einen Seite hervorgehobene Form aufweist. Hinter dem hervorgehobenen Gehäuse, des Starters befindet sich ein Einspurrelais, das ein Antriebsritzel in einen nicht dargestellten Zahnkranz eines Verbrennungsmotors einrücken kann.The Fig. 1 shows in a perspective view a retaining flange 1, which is partially cut open. The retaining flange 1 is a symmetrical component with a centered circular opening 2 and mounting holes 3, 4. The mounting holes 3, 4 are used for fastening or screwing the retaining flange 1 on an intermediate flange 5 on the bearing plate 6 of an electric machine, not shown, for example, a starter for an internal combustion engine. The intermediate flange 5 has to screw the retaining flange 1 a plurality of threaded holes 7, 8, 9, which are formed offset by a few degrees to each other. The plurality of threaded holes 7, 8 and 9 are provided to use the retaining flange 1 as a rotary flange and thus to install the starter rotated according to the spatial conditions, since the starter does not have a rotationally symmetrical, but highlighted on the one hand shape. Behind the highlighted housing, the starter is a Einspurrelais that can engage a drive pinion in a ring gear, not shown, of an internal combustion engine.

Am Halteflansch 1 sind bezüglich der zentrierten Kreisöffnung 2 um 120° versetzte Befestigungslöcher 11, 12 ausgebildet, wobei das dritte Befestigungsloch vom Halteflansch 1 aufgrund der Schnittansicht nicht dargestellt ist. In einer anderen Ausführungsform sind die Befestigungslöcher um 90° zu einander versetzt. Über die Befestigungslöcher 11, 12 wird der Starter am Verbrennungsmotor montiert.On the retaining flange 1 with respect to the centered circular opening 2 offset by 120 ° mounting holes 11, 12 are formed, wherein the third mounting hole from the retaining flange 1 due to the sectional view is not shown. In another embodiment, the mounting holes are offset by 90 ° to each other. About the mounting holes 11, 12 of the starter is mounted on the engine.

In die zentrierte Krelsöffnung 2 ist eine ringförmige Wechselexzentrizität 13 eingesetzt Die Wechselexzentrizität 13 hat eine zur zentrierten Kreisöffnung 2 als Passung ausgebildete zentrische Kreisumfangsfläche 14 mit einer als Stufe wirkenden, nach außen hervorstehenden Schulter, die eine exzentrische Kreisumfangsfläche 15 bezüglich der zentrischen Kreisumfangsfläche 14 aufweist. Zur exzentrischen Kreisumfangsfläche 14 der Wechselexzentrizität 13 ist zentrisch ein kreisförmiges Loch 16 ausgebildet. Das zentrische Loch 16 ist eine zylindrische Fläche, die auf eine zylindrische, zum Lagerschild 6 zentrierte Fläche 17 eingepasst wird. Natürlich ist es auch möglich gemäß einem anderen Montageverfahren, zuerst die Wechselexzentrizität 13 gemäß einer nicht dargestellten Ausführungsform definiert auf die zylindrische Fläche 17 zu montieren. Die Wechselexzentrizität 13 kann am Halteflansch 1 formschlüssig gesichert sein. Der Halteflansch 1 wird dann auf die Wechselexzentrizität 13 geschoben, zentrisch zum Zwischenflansch 5 angeordnet und an dem der Zwischenflansch 5 befestigt.In the centered Krelsöffnung 2 an annular exchange eccentricity 13 is used The exchange eccentricity 13 has a centered circular opening 2 as a fit formed centric circular peripheral surface 14 with a step acting, outwardly projecting shoulder having an eccentric circular peripheral surface 15 with respect to the central circular peripheral surface 14. To the eccentric circumferential surface 14 of the eccentric rotation 13, a circular hole 16 is formed centrally. The central hole 16 is a cylindrical surface which is fitted on a cylindrical, centered to the bearing plate 6 surface 17. Of course, according to another mounting method, it is also possible to first mount the exchange eccentricity 13 on the cylindrical surface 17 in accordance with an embodiment not shown. The exchange eccentricity 13 can be secured positively on the retaining flange 1. The retaining flange 1 is then pushed onto the exchange eccentricity 13, arranged centrally to the intermediate flange 5 and secured to the intermediate flange 5.

Die Wechselexzentrizität 13, wie sie in Fig. 1 gezeigt wird, kann kraftschlüssig durch Pressen oder Klemmen oder Aufschrumpfen am Halteflansch 1 eingesetzt sein oder stoffschlüssig verbunden, beispielsweise eingeklebt, sein. Die Wechselexzentrizität 13 ist eine Montagelehre, um den Halteflansch 1 mit dem zentrischen Lagerschild 6 in einem definiert radialen Abstand in einer zylindrischen, nicht gezeigten Öffnung eines Gehäuses einer Verbrennungskraftmaschine bezüglich einem Zahnkranz zu positionieren. Durch die Exzentrizität wird der radiale Abstand zwischen dem Einspurritzel des Starters und Zahnkranz festgelegt. In der zentrischen Position wird der Halteflansch 1 mittels Schrauben, die in die Gewindebohrungen 7, 8 und 9 eingeschraubt werden, befestigt.The exchange eccentricity 13, as in Fig. 1 is shown, may be non-positively inserted by pressing or clamping or shrinking on the retaining flange 1 or cohesively connected, for example, glued be. The exchange eccentricity 13 is an assembly jig for positioning the retaining flange 1 with the centric bearing plate 6 at a defined radial distance in a cylindrical, not shown, opening of a housing of an internal combustion engine with respect to a ring gear. Due to the eccentricity of the radial distance between the Einpurritzel the starter and sprocket is set. In the central position of the retaining flange 1 by means of screws which are screwed into the threaded holes 7, 8 and 9, attached.

Die Fig. 2 zeigt den Halteflansch 1 mit der Wechselexzentrizität 13 in einer auf die zylindrische Fläche 17 des Lagerschilds 6 eingesetzten Position. Der Halteflansch 1 ist noch nicht am Zwischenflansch 5 mit Schrauben in den Gewindebohrungen 7 verschraubt.The Fig. 2 shows the retaining flange 1 with the exchange eccentricity 13 in a position used on the cylindrical surface 17 of the bearing plate 6. The retaining flange 1 is not bolted to the intermediate flange 5 with screws in the threaded holes 7.

Die Fig. 3 zeigt in einer Draufsicht die Wechselexzentrizität 13 mit einer symmetrischen zentrischen Kreisumfangsfläche 14, in der das kreisförmige Loch 16 zentrisch, also koaxial zur Drehachse 20 ausgebildet ist. Vorzugsweise zur präzisen Montage ist eine Passung am kreisförmigen Loch 16 bezüglich der zylindrischen Fläche 17 am Lagerschild 6 ausgebildet. Erfindungsgemäß ist eine zylindrische Kreisumfangsfläche 15, die als Schulter vor der Kreisumfangsfläche 14 absteht, zu der Kreisumfangsfläche 14 exzentrisch ausgebildet. Mit der exzentrischen Kreisumfangsfläche 15 wird der Halteflansch am nicht dargestellten Gehäuse der Verbrennungskraftmaschine definiert eingesetzt.The Fig. 3 shows in a plan view the exchange eccentricity 13 with a symmetrical central circumferential surface 14, in which the circular hole 16 is formed centrally, ie coaxially to the axis of rotation 20. Preferably, for precise mounting a fit on the circular hole 16 with respect to the cylindrical surface 17 is formed on the bearing plate 6. According to the invention, a cylindrical circumferential surface 15, which protrudes as a shoulder in front of the circular peripheral surface 14, formed eccentrically to the circular peripheral surface 14. With the eccentric circumferential surface 15 of the retaining flange is used defined at the housing of the internal combustion engine, not shown.

Die Fig. 4 zeigt in einer aufgeschnittenen Seitenansicht den Halteflansch 1, wie er beispielsweise in der Fig. 1, 2 dargestellt ist, mit einem Befestigungsloch 12. In die zentrierte Kreisöffnung 2 am Halteflansch 1 ist die Wechselexzentrizität 13 mit der zentrischen Kreisumfangsfläche 14 eingesetzt. Die Wechselexzentrizität 13 ist bis zur Schulter eingeschoben und verbreitert das einpassbare zentrische, kreisförmige Loch 16 in der Tiefe. Die Schulter bildet die exzentrische Kreisumfangsfläche 15 zum passgenauen Einsatz in das Gehäuse der Verbrennungskraftmaschine.The Fig. 4 shows in a cutaway side view of the retaining flange 1, as shown for example in the Fig. 1 . 2 is shown, with a mounting hole 12. In the centered circular opening 2 on the retaining flange 1, the eccentric eccentricity 13 is used with the central circular peripheral surface 14. The exchange eccentricity 13 is inserted to the shoulder and widens the adjustable central circular hole 16 in depth. The shoulder forms the eccentric circumferential surface 15 for accurate use in the housing of the internal combustion engine.

Durch den in den Fig. 1 - 4 gezeigten Halteflansch 1 sind mindestens zwei Funktionen realisiert, zum einen ist der Halteflansch 1 als Drehflansch ausgebildet, um den Starter an die räumlichen Anforderungen bei der Verbrennungskraftmaschine anzupassen, zum anderen weist er einen variablen exzentrischen Aufbau auf, mit dem eine Exzentrizität des Antriebsritzels zum Zahnkranz definiert einstellbar ist. Durch einen solchen modularen Aufbau, einem Drehflansch und einem Exzentrizitätseinsatz als Wechselexzentrizität kann somit ein breites Anwendungsfeld mit Standardkomponenten ohne Änderung der Werkzeuge abgedeckt werden. Es muss also nicht für jede individuelle Exzentrizitätsanforderung ein neuer exzentrischer, spezifischer, einteiliger Drehflansch gefertigt werden.By in the Fig. 1 - 4th shown retaining flange 1 at least two functions are realized, on the one hand, the retaining flange 1 is designed as a rotary flange to adapt the starter to the spatial requirements in the internal combustion engine, on the other hand, it has a variable eccentric structure with which defines an eccentricity of the drive pinion to the ring gear is adjustable. By such a modular design, a rotary flange and an eccentricity as exchange eccentricity thus a wide range of applications with standard components without changing the tools can be covered. So it does not have to be made for each individual eccentricity requirement, a new eccentric, specific, one-piece rotary flange.

Der Halteflansch 1 und die Wechselexzentrizität 13 sind vorzugsweise aus Metall hergestellt. Sie können auch aus einem elektrisch isolierenden Werkstoff, einem keramischen Werkstoff, Kunststoff- oder Verbundwerkstoff hergestellt sein, solange die notwendigen Festigkeiten erreicht werden.The retaining flange 1 and the exchange eccentricity 13 are preferably made of metal. They can also be made of an electrically insulating material, a ceramic material, plastic or composite material, as long as the necessary strengths are achieved.
