Wälzlager mit Encoderring und Verfahren zu dessen Montage Rolling bearing with encoder ring and method for its assembly
Beschreibung description
Gebiet der Erfindung Field of the invention
Die Erfindung betrifft ein Wälzlager und ein Verfahren zu dessen Fertigung mit radial übereinander angeordneten Lagerringen und zwischen diesen abwälzenden Wälzkörpern und einer Drehzahlerfassungseinrichtung mit einem auf einem Lagerring angeordneten, aus einem Trägerteil und einem Magnetteil gebildeten Encoderring.  The invention relates to a rolling bearing and a method for the production thereof with radially superimposed bearing rings and between these rolling rolling elements and a speed detection device with a arranged on a bearing ring, formed from a support member and a magnetic part encoder ring.
Hintergrund der Erfindung Background of the invention
Wälzlager, beispielsweise Radlager von Kraftfahrzeugen wie PKW oder NKW weisen radial übereiander angeordnete Lagerringe, beispielsweise einen feststehenden, beispielsweise an einem Radträger aufgenommenen Außenring und einen gegenüber diesem verdrehbaren Innenring auf. Um beispielsweise ein Antiblockiersystem betreiben zu können, werden Drehkennwerte wie die Differenzdrehzahl und deren zeitliche Gradienten zwi- sehen Außenring und Innenring und damit eines an dem Innenring befestigten Rads von einer Drehzahlerfassungseinrichtung erfasst und in einem Steuergerät ausgewertet. Hierbei ist an dem Innenring, wie beispielsweise aus der DE 10 201 1 003 703 A1 bekannt, ein Encoderring angeordnet, der aufgrund seiner Ausbildung bei Verdrehung des Innenrings an einem Dreh- zahlsensor inkrementelle Signale erzeugt. Der Encoderring kann dabei aus einem Trägerteil und einer auf diesem angeordneten magnetischen Be- schichtung gebildet sein, der an einer magnetisch empfindlichen Sensorfläche des Drehzahlsensors über den Drehwinkel des Innenrings wechselnde Signale erzeugt. Durch die magnetischen Eigenschaften der Encoderringe sind diese während der Montage des Wälzlagers schwierig vorzuhalten, eine Vereinzelung durch die Magnetkräfte aneinander gebundener Encoderringe kann einen erhöhten Herstellaufwand erfordern. Rolling, for example, wheel bearings of motor vehicles such as cars or commercial vehicles have radially superimposed bearing rings, such as a fixed, for example, received on a wheel outer ring and a rotatable relative to this inner ring. To operate, for example, an anti-lock braking system, rotational characteristics such as the differential speed and their temporal gradient between outer ring and inner ring and thus a wheel attached to the inner ring are detected by a speed detection device and evaluated in a control unit. Here, on the inner ring, as known for example from DE 10 201 1 003 703 A1, an encoder ring is arranged, which generates incremental signals due to its formation upon rotation of the inner ring on a speed sensor. The encoder ring can be formed from a carrier part and a magnetic coating arranged thereon, which changes at a magnetically sensitive sensor surface of the rotational speed sensor via the rotational angle of the inner ring Signals generated. Due to the magnetic properties of the encoder rings these are difficult vorzuhalten during installation of the bearing, a separation by the magnetic forces of bonded encoder rings may require an increased manufacturing effort.
Aufgabe der Erfindung Object of the invention
Aufgabe der Erfindung ist daher, ein Wälzlager und ein Verfahren zu dessen Montage mit einer einfachen Handhabung und Vereinzelung der Encoderringe vorzuschlagen.  The object of the invention is therefore to propose a rolling bearing and a method for its assembly with a simple handling and separation of the encoder rings.
Allgemeine Beschreibung der Erfindung General description of the invention
Die Aufgabe wird durch den Gegenstand des Anspruchs 1 gelöst. Die von diesem abhängigen Ansprüche geben vorteilhafte Ausführungsformen des Gegenstands des Anspruchs 1 wieder. Die Aufgabe wird weiterhin durch die Merkmale des Verfahrens gemäß Anspruch 10 gelöst.  The object is solved by the subject matter of claim 1. The dependent claims give advantageous embodiments of the subject matter of claim 1 again. The object is further achieved by the features of the method according to claim 10.
Das vorgeschlagene Wälzlager enthält zwei übereinander Angeordnete Lagerringe, beispielsweise einen Innenring, einen Außenring und zwischen diesen auf einer oder mehreren Wälzkörperreihen abwälzenden Wälzkörpern und einer Drehzahlerfassungseinrichtung mit einem auf einem drehen- den der Lagerringe angeordneten, aus einem Trägerteil und einem Magnetteil gebildeten Encoderring. Bevorzugt ist das Trägerteil aus Blech, beispielsweise mittels eines kombinierten Stanz-/Umformverfahrens und/oder dergleichen oder einem Blechstreifen mittels eines Stanz-/Biegeverfahrens und gegebenenfalls einer Verbindung dessen Enden zu einem geschlosse- nen Ringteil hergestellt. Das Magnetteil kann aus einem entsprechenden magnetischen Masseteil, einem Magnetpartikel enthaltenden Teil oder als Beschichtung des Trägerteils vorgesehen sein. Magnetteil und Trägerteil sind miteinander formschlüssig, reibschlüssig und/oder stoffschlüssig verbunden und/oder verklebt. Zur Bildung von aneinander haftenden, jedoch leicht vereinzelbaren Losen von Encoderringen vor dem Fügen dieser auf dem Innenring oder einem mit diesem fest verbundenen Bauteil ist an zumindest einer axialen Stirnseite einer durch Trägerteil und Beschichtung gebildeten Kontur ein radial verjüngtes Distanzprofil vorgesehen. Durch die Ausbildung eines derartigen Distanzprofils wird eine Kontaktfläche zwischen koaxial aneinander haftender Encoderringe derart verringert, dass diese zwar verliersicher aneinanderhaften, jedoch mit geringer Kraft vereinzelt werden können. Die Encoderringe können dabei auf einem Rundkörper mit einem im Wesentlichen einem Innendurchmesser der Encoderringe entsprechenden Außendurchmesser aufgefädelt sein. Die Distanzprofile können über den Umfang umlaufend als Ringprofile oder aus mehreren über den Umfang verteilten Segmenten oder Kontaktpunkten gebildet sein. The proposed rolling bearing comprises two superimposed bearing rings, for example an inner ring, an outer ring and between these rolling on one or more Wälzkörperreihen rolling elements and a speed detection device with an arranged on a rotating of the bearing rings, formed from a support member and a magnetic part encoder ring. Preferably, the carrier part made of sheet metal, for example by means of a combined punching / forming process and / or the like or a sheet metal strip by means of a punching / bending process and optionally a compound whose ends are made to a closed ring part. The magnetic part may be provided from a corresponding magnetic mass part, a magnetic particle-containing part or as a coating of the support part. Magnetic part and carrier part are positively connected to each other, frictionally engaged and / or materially bonded and / or glued. To form adhering, but easily isolatable lots of encoder rings before joining them on the inner ring or a permanently connected to this component is at least one axial end side of a carrier part and coating formed contour provided a radially tapered spacer profile. By forming such a spacer profile, a contact surface between coaxially adhering encoder rings is reduced so that they may be captive but stick together, but can be separated with little force. The encoder rings can be threaded onto a round body with an outer diameter corresponding essentially to an inner diameter of the encoder rings. The spacer profiles may be circumferentially formed over the circumference as ring profiles or from several distributed over the circumference segments or contact points.
Insbesondere wenn keine oder nur sehr geringe, beispielsweise durch fer- romagnetische Induktion hervorgerufene magnetische Anziehung zwischen den Encoderringen vorgesehen sein soll, kann das Distanzprofil an dem Trägerteil vorgesehen sein. Hierbei kann ein Anlagekontakt zum Trägerteil oder zum Magnetteil des benachbarten Encoderrings ausgebildet werden. Alternativ kann das Distanzprofil an dem Magnetteil vorgesehen sein, wobei der Anlagekontakt zu einem Trägerteil oder einem Magnetteil der benachbarten Encoderringe ausgebildet sein kann. In particular, if no or only very little, for example caused by ferromagnetic induction induced magnetic attraction between the encoder rings should be provided, the spacer profile may be provided on the support member. In this case, a contact contact with the carrier part or the magnetic part of the adjacent encoder ring can be formed. Alternatively, the spacer profile may be provided on the magnetic part, wherein the abutment contact may be formed to a support member or a magnetic part of the adjacent encoder rings.
Das Trägerteil ist in bevorzugter Weise im Querschnitt winkelig mit einem sich axial erstreckenden und einem radial ausgerichteten Schenkel ausge- bildet. Hierbei kann der axial ausgerichtete Schenkel auf den Innenring auf- gepresst sein und das Magnetteil den radial ausgerichteten Schenkel teilweise oder vollständig abdecken oder ein- oder beidseitig radial überdecken. Beispielsweise kann das Distanzprofil an einer axialen Erweiterung wie beispielsweise einem axial ausgerichteten Schenkel vorgesehen sein. Hierzu kann die Stirnfläche des axial erweiterten Schenkels eine entsprechende Phase aufweisen, die die Blechstärke des Trägerteils verringert. Weiterhin kann vorgesehen sein, das Distanzprofil an einem radial verlaufenden Rücken eines im Querschnitt abgewinkelten Encoderrings anzuordnen, wobei dieses aus dem Trägerteil oder dem Magnetteil mittels entspre- chender axialer Ausformungen, Ausstellungen und dergleichen angeordnet ist.  The carrier part is preferably angularly formed in cross-section with an axially extending and a radially oriented leg. In this case, the axially aligned limb can be pressed onto the inner ring and the magnet part can partially or completely cover the radially aligned limb or cover radially on one or both sides. For example, the spacer profile may be provided on an axial extension, such as an axially oriented leg. For this purpose, the end face of the axially expanded leg may have a corresponding phase, which reduces the thickness of the support member. Furthermore, it can be provided to arrange the spacer profile on a radially extending back of an angled cross-section encoder ring, which is arranged from the carrier part or the magnetic part by means of corresponding axial formations, exhibitions and the like.
Gemäß einer besonders vorteilhaften Ausführungsform ist an dem Encoder- ring ein Element zur Rückhaltung von für die Schmierung der Wälzkontakte zwischen den Lagerringen und Wälzkörper vorgesehenem Schmiermittel, beispielsweise Fett oder Öl vorgesehen. Hierzu kann der Encoderring gegenüber einer im Querschnitt gewinkelten Anordnung zweier Schenkel einen radial erweiterten Ringbord aufweisen. Beispielsweise kann an einem axial erweiterten Schenkel des Encoderrings, bevorzugt an dessen Stirnseite ein radial erweiterter Ringbord vorgesehen sein. Beispielsweise kann der Ringbord an dem Trägerteil oder an dem Magnetteil bevorzugt einteilig vorgesehen sein. Um insbesondere eine verbesserte Entformung des Encoder- rings während dessen Herstellung zu erzielen, kann ein Außenumfang des Encoderringes, beispielsweise das Magnetteil mit gegen den Wälzkontakt abfallendem, konischem Profil ausgebildet sein. Beispielsweise kann der Ringbord stirnseitig des Wälzlagers angeordnet sein, wobei ausgehend von dem Ringbord der Außenumfang in Richtung der Wälzkontakte abfällt. According to a particularly advantageous embodiment, at the encoder ring provided an element for retaining provided for the lubrication of the rolling contacts between the bearing rings and rolling elements lubricant, such as grease or oil. For this purpose, the encoder ring may have a radially enlarged annular rim in relation to a cross-sectionally angled arrangement of two legs. For example, may be provided on an axially enlarged leg of the encoder ring, preferably on the front side of a radially expanded ring board. For example, the ring board may preferably be provided integrally on the carrier part or on the magnetic part. In order in particular to achieve improved demolding of the encoder ring during its production, an outer circumference of the encoder ring, for example the magnetic part with sloping against the rolling contact, conical profile can be formed. For example, the annular flange may be arranged on the front side of the rolling bearing, wherein, starting from the annular flange, the outer circumference drops in the direction of the rolling contacts.

Ausführliche Beschreibung der Figuren Detailed description of the figures
Die Figur 1 zeigt einen Teilschnitt des um die Drehachse d angeordneten Wälzlagers 1 mit dem als Innenring ausgebildeten Lagerring 2 und dem als Außenring ausgebildeten, im Tragteil 7 aufgenommenen Lagerring 3. Der Lagerring 3 dient beispielsweise als Nabe zur Aufnahme eines Rads eines Kraftfahrzeugs, während der Außenring mit einem Radträger eines Kraftfahrzeugs verbunden ist. In der gezeigten Ausführungsform wälzen auf zwei Wälzlagerreihen angeordnete Wälzkörper 4 zwischen den Lagerringen 2, 3 an entsprechenden Wälzflächen des Lagerrings 3 und Lagerschalen 5, 6 des Lagerteils 2 ab. Das Wälzlager 1 ist beidseitig mittels der Dichtung 8 und der Dichtkappe 9 abgedichtet. Das Wälzlager 1 verfügt über eine Drehzahlerfassungseinrichtung mit dem auf dem Lagerring 2 aufgenommenen Encoderring 10 und einem benachbart zu diesem außerhalb der Dichtkappe 9 bevorzugt fest mit dem Lagerring 3 oder einem diesem zugeordneten Bauteil angeordneten - nicht dargestellten - Drehzahlsensor.  1 shows a partial section of the arranged around the axis of rotation d bearing 1 with the formed as an inner ring bearing ring 2 and formed as an outer ring, received in the support member 7 bearing ring 3. The bearing ring 3 serves for example as a hub for receiving a wheel of a motor vehicle during the Outer ring is connected to a wheel carrier of a motor vehicle. In the embodiment shown, rolling elements 4 arranged on two rows of rolling bearings roll between the bearing rings 2, 3 on corresponding rolling surfaces of the bearing ring 3 and bearing shells 5, 6 of the bearing part 2. The rolling bearing 1 is sealed on both sides by means of the seal 8 and the sealing cap 9. The roller bearing 1 has a speed detection device with the recorded on the bearing ring 2 encoder ring 10 and adjacent to this outside of the sealing cap 9 preferably fixed to the bearing ring 3 or a component associated therewith - not shown - speed sensor.
Der Encoderring 10 ist aus dem Trägerteil 1 1 und dem Magnetteil 12 gebildet. Das Trägerteil 1 1 ist bevorzugt aus Blech hergestellt und im Querschnitt gewinkelt mit dem sich axial erstreckenden Schenkel 13 und dem sich radial erstreckenden Schenkel 14 ausgebildet, wobei der Encoderring 10 mittels des Schenkels 13 auf den Lagerring 2 aufgepresst ist und das Magnetteil 12 an dem Schenkel 14 mit geringem Spiel zu der Dichtkappe 9 aufgenommen ist. The encoder ring 10 is formed from the carrier part 1 1 and the magnetic member 12. The support member 1 1 is preferably made of sheet metal and angled in cross section with the axially extending leg 13 and the radially extending leg 14 is formed, wherein the encoder ring 10 is pressed by means of the leg 13 on the bearing ring 2 and the magnetic member 12 on the leg 14 is added to the sealing cap 9 with little play.
Bei der Montage des Wälzlagers 1 werden dem Encoderring 10 entspre- chende Encoderringe in vorgegebenen Losgrößen konzentrisch zueinander gestapelt, beispielsweise auf entsprechenden Rundkörpern wie Zylindern, Hülsen und dergleichen vorgehalten und zur Bestückung des Wälzlagers 1 vereinzelt und auf den Lagerring 2 aufgepresst. Um den Widerstand der Vereinzelung bei infolge magnetischer Anziehung der Magnetteile 12 der Encoderringe untereinander zu verringern und eine einfache Handhabung zu erzielen, ist die Kontur des Trägerteils 1 1 und des Magnetteils 12 so aus- gebildet, dass an einer Stirnseite der Encoderringe 10 ein sich radial verjüngendes Distanzprofil 15 vorgesehen ist, welches eine gegenüber der Kontur der Stirnseite verringerte Anlagefläche 16 gegenüber dem benachbarten Encoderring einer noch nicht vereinzelten Vorhaltemenge von Encoderringen aufweist und daher leicht von diesem gelöst werden kann. Zur detaillier- ten Ausbildung der Kontur des Encoderrings 10 siehe Figur 3. During assembly of the rolling bearing 1, encoder rings corresponding to the encoder ring 10 are stacked concentrically in predetermined batch sizes, for example, on corresponding round bodies such as cylinders, sleeves and the like, and for equipping the rolling bearing 1 isolated and pressed onto the bearing ring 2. In order to reduce the resistance of the singulation as a result of magnetic attraction of the magnetic parts 12 of the encoder rings with each other and to achieve easy handling, the contour of the support member 1 1 and the magnetic member 12 is formed so that at one end of the encoder rings 10 is a radially tapered spacer profile 15 is provided, which has a relation to the contour of the end face reduced contact surface 16 relative to the adjacent encoder ring not yet isolated Vorhaltemenge of encoder rings and therefore can be easily solved by this. For a detailed description of the contour of the encoder ring 10, see FIG. 3.
Die Figur 2 zeigt das gegenüber dem Wälzlager 1 der Figur 1 abgeänderte Wälzlager 1 a im Teilschnitt mit dem Lagerring 2a. Das Wälzlager 1 a ist mit einem abgeänderten Encoderring 10a versehen, dessen Magnetteil 12a sich über beide Schenkel 13a, 14a des Trägerteils 1 1 a erstreckt. Desweiteren bildet das Magnetteil 12a den radial erweiterten Ringbord 17a aus, der als Rückhalteelement zur Rückhaltung von an den Wälzflächen des Wälzlagers 1 a vorgesehenem Schmiermittel dient. Die sich an den Ringbord 17a axial anschließende, eben dargestellte Umfangsfläche 19a kann - wie gestrichelt dargestellt - konisch ausgebildet sein, um beispielsweise eine besseren Entformung während dessen Herstellung zu erzielen. Desweiteren kann während des Aufbringens wie Aufpressen des Encoderrings 10a auf den Lagerring 2a ein Kraftansatz direkt oder zumindest im Wesentlichen auf der radialen Höhe des sich radial erweiternden Schenkels 13a erfolgen, so dass das Trägerteil 1 1 a weniger elastisch um die Schenkelachse verdreht wird. Der Encoderring 10a weist an dessen Stirnseite das am Magnetteil 12a vorgesehene Distanzprofil 15a auf. Hierzu übergreift das Magnetteil 12a den axialen Schenkel 13a des Trägerteils 1 1 a an dessen stirnseitigem Ende. Es versteht sich, dass alternativ oder zusätzlich zu einem axial angeordneten Erregungsmuster des Magnetteils 12a ein radiales Erregungsmuster auf dem Magnetteil 12a vorgesehen sein kann, so dass bei zusätzlicher oder alternativer Anordnung eines Drehzahlsensors mit einer radial benachbarten Sensorfläche eine radiale Abtastung des Encoderrings 10a durch einen ent- sprechend angeordneten Drehzahlsensor und eine entsprechend geometrisch ausgebildeten Dichtkappe erfolgen kann. Der nicht vereinzelte Encoderring 10a ist in Figur 6 dargestellt. FIG. 2 shows the antifriction bearing 1 a modified in comparison to the roller bearing 1 of FIG. 1 in partial section with the bearing ring 2 a. The rolling bearing 1 a is provided with a modified encoder ring 10 a, the magnetic part 12 a extends over both legs 13 a, 14 a of the support part 1 1 a. Furthermore, the magnetic part 12a forms the radially expanded annular flange 17a, which serves as a retaining element for the retention of provided on the rolling surfaces of the rolling bearing 1 a lubricant. The peripheral surface 19a, which adjoins the annular flange 17a axially, can be conical, as shown in dashed lines, in order, for example, to achieve better demolding during its production. Furthermore, during application such as pressing the encoder ring 10a onto the bearing ring 2a, a force approach can take place directly or at least substantially at the radial height of the radially widening leg 13a, so that the support part 11a is less elastically rotated around the leg axis. The encoder ring 10a has at its end face on the provided on the magnetic part 12a spacer profile 15a. For this purpose, the magnetic part 12 overlaps the axial leg 13a of the support member 1 1 a at the end-face end. It is understood that as an alternative or in addition to an axially arranged excitation pattern of the magnetic member 12a, a radial excitation pattern may be provided on the magnetic member 12a, so that in additional or alternative arrangement of a rotational speed sensor with a radially adjacent sensor surface, a radial scanning of the encoder ring 10a by a ent - speaking arranged rotational speed sensor and a corresponding geometrically formed sealing cap can be done. The non-isolated encoder ring 10a is shown in FIG.
Die Figur 3 zeigt im Schnitt nicht vereinzelte Encoderringe 10, 10', die auf einem lediglich angedeuteten Rundkörper 18 konzentrisch zueinander in jeweils gleicher Anordnung gestapelt aufgenommen sind. Zur Montage der Encoderringe 10, 10' wird der oberste Encoderring 10 entnommen und auf den Lagerring 2 des Wälzlagers 1 (Figur 1 ) gepresst. Aufgrund der gegenüber einer Blechstärke der Trägerteile 1 1 , 1 1 ' verringerten Anlageflächen 16, 16' der Distanzprofile 15, 15' können die Encoderringe 10, 10' mit verminderter Kraft vereinzelt werden. Die Distanzprofile 15, 15' werden beispielsweise durch spanendes oder werkzeugfallend formendes Anphasen der Trägerteile 1 1 , 1 1 ' hergestellt.  FIG. 3 shows, on average, non-isolated encoder rings 10, 10 ', which are received stacked on a merely indicated round body 18 concentrically with one another in the same arrangement in each case. For mounting the encoder rings 10, 10 ', the uppermost encoder ring 10 is removed and pressed onto the bearing ring 2 of the rolling bearing 1 (FIG. 1). Due to the compared to a plate thickness of the support members 1 1, 1 1 'reduced contact surfaces 16, 16' of the spacer profiles 15, 15 ', the encoder rings 10, 10' can be isolated with reduced force. The spacer profiles 15, 15 'are produced, for example, by cutting or die-forming shaping of the support parts 11, 11'.
Die Figur 4 zeigt gegenüber den Encoderringen 10, 10' der Figuren 1 und 3 abgeänderte Encoderringe 10b, 10b' mit den Trägerteilen 1 1 b, 1 1 b' und den Magnetteilen 12b, 12b', die an den stirnseitigen Enden der Trägerteile 1 1 b, 1 1 b' über den radial erweiterten Ringbord 17b, 17b' verfügen, der als Rückhalteelement für Schmiermittel dient. Dementsprechend sind die Distanzprofile 15b, 15b' an einem Übergang zwischen dem axialen Schenkel 13b, 13b' und dem Ringbord 17b, 17b' vorgesehen, bevorzugt angeprägt.  The Figure 4 shows compared to the encoder rings 10, 10 'of Figures 1 and 3 modified encoder rings 10b, 10b' with the support parts 1 1 b, 1 1 b 'and the magnetic parts 12 b, 12 b', at the front ends of the support members 1 first b, 1 1 b 'have the radially expanded annular flange 17 b, 17 b', which serves as a retaining element for lubricant. Accordingly, the spacer profiles 15b, 15b 'at a transition between the axial leg 13b, 13b' and the ring board 17b, 17b 'provided, preferably stamped.
Die Figur 5 zeigt im Schnitt die aneinander angeordnet aufgereihten Encoderringe 10c, 10c', bei denen beide Schenkel 13c, 13c', 14c, 14c' der Trägerteile 1 1 c, 1 1 c' von den Magnetteilen 12c, 12c' überdeckt sind. Demzufolge sind die Distanzprofile 15c, 15c' aus den Magnetteilen 12c, 12c' gebil- det.  5 shows in section the juxtaposed arrayed encoder rings 10c, 10c ', in which both legs 13c, 13c', 14c, 14c 'of the support members 1 1 c, 1 1 c' of the magnetic parts 12c, 12c 'are covered. As a result, the spacer profiles 15c, 15c 'are formed from the magnetic parts 12c, 12c'.
Die Figur 6 zeigt die in Figur 2 dargestellten, noch nicht vereinzelten Encoderringe 10a, 10a', die im Unterschied zu den Encoderringen 10c, 10c' der Figur 5 den Ringbord 17a, 17a' aufweisen. Dementsprechend sind die Distanzprofile 15a, 15a' den Distanzprofilen 15c, 15c' der Encoderringe 10c, 10c' der Figur 5 ähnlich.  FIG. 6 shows the encoder rings 10a, 10a ', which are not yet singled, and which, in contrast to the encoder rings 10c, 10c' of FIG. 5, have the ring flange 17a, 17a '. Accordingly, the spacer profiles 15a, 15a 'are similar to the spacer profiles 15c, 15c' of the encoder rings 10c, 10c 'of FIG.
Im Unterschied zu den Encoderringen 10a, 10a' der Figur 6 ist an den Encoderringen 10d, 10d' der Figur 7 der Ringbord 17d, 17d' am stirnseitigen En- de des Schenkels 13d, 13d' des Trägerteils 1 1 d, 1 1 d' angeordnet. In contrast to the encoder rings 10a, 10a 'of FIG. 6, at the encoder rings 10d, 10d' of FIG. 7 the ring board 17d, 17d 'at the front end de of the leg 13d, 13d 'of the support member 1 1 d, 1 1 d' arranged.
