Description

Die Erfindung betrifft eine Antriebsvorrichtung für eine Waschmaschine mit einer innerhalb einer Lagerhülse eines an einer Bodenwand eines Laugenbehälters angebrachten, steifen Tragsterns über eine wenigstens annähernd horizontal liegende Welle gelagerten Wäschetrommel, wobei die Antriebseinrichtung an der Rückseite des Laugenbehälters montierbar ist und aus einem flachen Motor mit einem Ständertragteil und Erregerwicklungen und mit einem Läufer und magnetisierbaren Polen besteht und die Wäschetrommel direkt antreibt.The invention relates to a drive device for a washing machine with a mounted inside a bearing sleeve of a bottom wall of a tub, rigid carrying star via an at least approximately horizontal shaft mounted laundry drum, wherein the drive means is mounted on the back of the tub and a flat motor with a Ständerertragteil and exciter windings and with a rotor and magnetizable poles and drives the laundry drum directly.

Eine derartige Antriebsvorrichtung ist aus der DE 39 27 426 A1 bekannt. Darin besteht das Ständertragteil aus einem Isolierteil, auf dem die Erregerwicklungen montiert sind. Das Isolierteil ist kreisringförmig und auf die Lagerhülse des Tragsterns geschoben. Der glockenförmige Läufer umgreift diese Montageeinheit und ist mit einer Schraubkappe am Wellenzapfen der Wäschetrommel befestigt, der die Lagerhülse nach hinten überragt. Zur Montage des Motors muß daher zunächst das Ständertragteil, mit den Erregerwicklungen (vormontiert) auf die Lagerhülse geschoben werden. Anschließend muß die Läuferglocke auf den Wellenzapfen gesetzt und ver-schraubt werden. Die für den ordnungsgemäßen Betrieb des Motors nötige Einhaltung der inneren Toleranzen (hauptsächlich die Positionierung der Erregerwicklungen in Bezug auf die magnetisierbaren Läuferpole) kann dabei jedoch keineswegs gewährleistet werden, weil im Montagewerk für Waschmaschinen keine Zeit und keine Arbeitsmittel für die Einhaltung dieser Toleranzen zur Verfügung stehen.
Aus EP 0 779 388 A2 ist eine Anbriebsvorrichtung für eine Waschmaschine bekannt, bei der der Rotor mit dem Stator bereits von dem Einbau in die Waschmaschine über Wälzlager verbunden ist.Such a drive device is known from DE 39 27 426 A1. Therein, the stator support part consists of an insulating part, on which the excitation windings are mounted. The insulating part is annular and pushed onto the bearing sleeve of the supporting star. The bell-shaped rotor surrounds this mounting unit and is fastened with a screw cap on the shaft journal of the laundry drum, which projects beyond the bearing sleeve to the rear. To mount the motor, therefore, first the stator support part, with the excitation windings (pre-assembled) must be pushed onto the bearing sleeve. Then the rotor bell must be placed on the shaft journal and screwed. The necessary for the proper operation of the engine compliance with the internal tolerances (mainly the positioning of the field windings in relation to the magnetizable rotor poles), however, can not be guaranteed, because in the assembly plant for washing machines no time and no tools for compliance with these tolerances available ,
From EP 0 779 388 A2 a Anbriebsvorrichtung for a washing machine is known in which the rotor is already connected to the stator of the installation in the washing machine via roller bearings.

Der Erfindung liegt die Aufgabe zugrunde, die eingangs definierte Antriebsvorrichtung so zu gestalten, daß der Motor fertig vormontiert und geprüft beim Herstellerwerk für Waschmaschinen angeliefert werden kann, ohne daß beim Einbau des Motors an der Waschmaschine noch ein Eingriff nötig ist, der die Einhaltung der für den ordnungsgemäßen Betrieb des Motors erforderlichen Toleranzen gefährden könnte. Außerdem soll damit eine Montagevereinfachung im Waschmaschinenwerk einhergehen.The invention has for its object to design the initially defined drive device so that the engine ready pre-assembled and tested at the factory for washing machines can be delivered without the installation of the engine to the washing machine still requires intervention, the compliance of the could endanger the proper operation of the engine required tolerances. In addition, this should be accompanied by a simplification of assembly in the washing machine plant.

Erfindungsgemäß wird diese Aufgabe durch eine Antriebsvorrichtung gemäß Anspruch 1 gelöst. Auf diese Weise kann sicher gestellt werden, daß der Motor im dafür bestens ausgerüsteten Herstellerwerk fertig montiert und geprüft werden kann, ehe er einem Anwender, z.B. das Werk eines Waschmaschinenherstellers, geliefert wird.According to the invention, this object is achieved by a drive device according to claim 1. In this way it can be ensured that the engine can be assembled and tested in the manufacturer's factory equipped for this purpose before it can be used by a user, e.g. the work of a washing machine manufacturer, is delivered.

Zur Sicherheit wird man mindestens zwei solcher Arretierungsschrauben vorsehen.For safety you will provide at least two such locking screws.

In einer weiteren vorteilhaften Ausbildungsform der Erfindung ist aber anstelle mindestens einer von mehreren Arretierungsschrauben mindestens eine der Bohrungen des Lochbildes im Ständertragteil mit demselben Durchmesser wie die des Läufers und glattwandig ausgebildet und zur Lagesicherung während des Transports mit einem Arretierstift versehen.In a further advantageous embodiment of the invention but instead of at least one of a plurality of locking screws at least one of the holes of the hole pattern in the stator support member having the same diameter as that of the rotor and smooth-walled and provided for securing the position during transport with a locking pin.

Zur erleichterten Montage eines gemäß der Erfindung vormontierten Motors ist eine besonders vorteilhafte Weiterbildung der Erfindung dadurch gekennzeichnet, daß der Läufer die Form einer Glocke hat, deren zentrischer Teil als flache Scheibe ausgebildet ist und auf einem Kreis mit demselben Radius Zugangsbohrungen wie das Ständertragteil Befestigungsbohrungen und wie der Tragstern Gewindelöcher für die Montage des Motors am Tragstern hat.To facilitate assembly of a motor preassembled according to the invention, a particularly advantageous embodiment of the invention is characterized in that the rotor has the shape of a bell whose centric part is formed as a flat disc and on a circle with the same radius access holes as the stator support part mounting holes and how the star has threaded holes for mounting the motor on the star.

Zur Einsparung eines besonderen Ständertragteils kann die erfindungsgemäße Antriebsvorrichtung in der Weise vorteilhaft weitergebildet werden, daß das Ständertragteil durch einen Blechpaketring für die Erregerwicklungen gebildet ist.To save a special stator support part, the drive device according to the invention can be advantageously developed in such a way that the stator support part is formed by a laminated core ring for the field windings.

Bei einer vorstehend ausgeführten Vorrichtung kann zum besseren Schutz der Erregerwicklungen und der magnetisierbaren Pole in besonders vorteilhafter Weise der Blechpaketring auf der dem Tragstern zugewandten Seite mit einem tellerartig geformten Ring versehen sein, dessen Außenrand über eine Labyrinthdichtung an den Glockenrand reicht.In a device constructed above, for better protection of the exciter windings and the magnetizable poles, the laminated core ring on the side facing the carrier star can be provided with a dish-shaped ring whose outer edge extends over a labyrinth seal to the bell edge.

Beide vorgenannten Ausführungsformen haben außerdem den Vorteil, daß für die Arretierungsschrauben und -stifte keine anderen Löcher in der Läuferglocke vorhanden sein müssen als die für die Befestigung des Motors am Tragstern. Zur Montage des Motors an der Waschmaschine wird zunächst der arretierte Motor über seine Läuferglocke mit dem Wellenzapfen der Wäschetrommel verbunden. Dann wird ein Arretierstift oder eine der Arretierschrauben heraus gezogen und die zum Tragstern lochüberdeckende Drehposition des Motors gesucht und in das eine freigewordene Loch eine Montageschraube eingedreht Danach wird der Reihe nach mit allen Löchern so verfahren.Both of the above embodiments also have the advantage that for the locking screws and pins no other holes must be present in the rotor bell than that for the attachment of the engine to the star carrier. To mount the motor to the washing machine, the locked motor is first connected via its rotor bell with the shaft journal of the laundry drum. Then, a locking pin or one of the locking screws is pulled out and searched for the supporting star hole hole covering rotational position of the engine and in the a vacant hole screwed a mounting screw Thereafter, the process in sequence with all holes.

Im übrigen ist die erfindungsgemäße Antriebsvorrichtung vorteilhafterweise am besten dadurch geschützt, daß das Ständertragteil sich über die Erregerwicklungen hinaus erstreckt und sein Rand zusammen mit dem der Glocke eine Labyrinthdichtung bildet.Moreover, the drive device according to the invention is advantageously best protected by the fact that the stator support part extends beyond the excitation windings out and forms its edge together with the bell a labyrinth seal.

Desgleichen können die Erregerwicklungen und Pole auch in Richtung auf das Drehzentrum hin besser durch eine Fortbildung der Erfindung geschützt werden, in der das Ständertragteil und/oder die Glocke auf der dem Zwischenraum zugewandten Seite mit einem umlaufenden Kragen versehen ist, der mit dem Gegenpart an der Glocke bzw. am Ständertragteil eine Labyrinthdichtung bildet.Similarly, the excitation windings and poles can be better protected in the direction of the center of rotation by a development of the invention, in which the stator support member and / or the bell is provided on the side facing the gap with a circumferential collar which is connected to the counterpart on the Bell or at the stator bearing part forms a labyrinth seal.

Eine andere besonders vorteilhafte Fortbildung der Erfindung ist dadurch gekennzeichnet, daß das Ständertragteil eine zentrische Führungshülse aufweist, die über eine definierte Schiebesitz-Passung auf einen Außenzylinder der Lagerhülse des Tragsterns setzbar ist. Diese Ausbildung erleichtert die Montage des Motors an der Waschmaschine dadurch, daß der noch arretierte Motor mit seiner Führungshülse lagesicher auf die Lagerhülse aufgesetzt werden kann, so daß die zentrische Bohrung für die Befestigung der Läuferglocke am Wellenzapfen automatisch zentriert ist.Another particularly advantageous development of the invention is characterized in that the stator support part has a central guide sleeve which can be placed on a defined outer sliding fit on an outer cylinder of the bearing sleeve of the support star. This design facilitates the installation of the motor to the washing machine in that the still locked motor can be placed securely on the bearing sleeve with its guide sleeve, so that the central bore for the attachment of the rotor bell is automatically centered on the shaft journal.

Der Tragstern 1 ist dreistrahlig. Sein nach oben gerichteter Strahl 2 liegt in der Zeichnungsebene der Fig. 1, 3. Die beiden nach unten gerichteten Strahlen zeigen nach hinten bzw. nach vorn aus der Zeichnungsebene hinaus und sind deshalb nicht dargestellt. Gemäß Fig. 1 ist der Tragstern 1 mittels nicht dargestellter Schrauben an der rückseitigen Bodenwand 3 des Laugenbehälters befestigt. Zur Lagerung des Wellenzapfens 4 der nicht dargestellten Wäschetrommel besitzt der Tragstern. 1 eine Lagerhülse 5 mit Wälzlagern. Außerdem erstreckt sich in Fig. 1 und 3 in derselben Richtung vom Tragstern 1 ausgehend ein Befestigungsflansch 6, an dem der Motor 7 verschraubt werden kann.The starlet 1 is three-jet. Its upwardly directed beam 2 lies in the plane of the drawing of Figs. 1, 3. The two downwardly directed rays point backwards or forwards out of the plane of the drawing and are therefore not shown. 1, the carrier star 1 is fastened by means not shown screws on the rear bottom wall 3 of the tub. For storage of the shaft journal 4 of the laundry drum, not shown, has the supporting star. 1 a bearing sleeve 5 with bearings. In addition, extending in Fig. 1 and 3 in the same direction starting from the star carrier 1, a mounting flange 6, to which the motor 7 can be screwed.

Der in Fig. 1 und 2 dargestellte Motor 7 hat ein tellerförmig gestaltetes Ständertragteil 8, dessen Außenrand 9 sich bis zum Rand der Läuferglocke 10 erstreckt und mit ihm zusammen eine Labyrinthdichtung 11 bildet. Auf dem auskragenden Abschnitt 12 des Ständertragteils 8 sind die Erregerwicklungen 13 mit ihren Blechlamellen 14 am Umfang verteilt. Sie stehen über einen Luftspalt den magnetisierbaren Polen 15 gegenüber, die am Innenumfang des Glockenrandes 16 des Läufers 10 befestigt sind.The motor 7 shown in Fig. 1 and 2 has a plate-shaped stator support member 8, the outer edge 9 extends to the edge of the rotor bell 10 and together with it forms a labyrinth seal 11. On the projecting portion 12 of the stator support part 8, the field windings 13 are distributed with their laminations 14 on the circumference. They are opposed by an air gap to the magnetizable poles 15, which are fastened to the inner circumference of the bell rim 16 of the rotor 10.

Das Ständertragteil 8 hat auf seiner zum Läufer 10 zeigenden Fläche einen Ring von Arretierungsaugen 17, die bis kurz vor die Innenfläche der Läuferglocke 10 reichen. Ihre Arretierungslöcher 18 sind glattwandig oder wie bei 19 mit Gewinde versehen. In die glattwandigen Arretierungslöcher 18 sind zum Transport Arretierungsstifte 20 gesteckt, die mit entsprechenden Arretierungslöchern 21 in der Läuferglocke 10 korrespondieren. Mindestens eines - besser zwei oder mehr - der Arretierungsaugen 17 hat Gewindelöcher 19 zum Einschrauben von Arretierungsschrauben 22, mit denen die Transportposition unverrückbar festgelegt werden kann. Zur genauen Tiefenpositionierung unter Wahrung des nötigen Abstandes der Läuferglocke 10 vom Ständertragteil 8 ist vor dem Einschrauben der Arretierungschrauben 22 eine Distanzhülse 23 einzusetzen.The stator support part 8 has on its surface facing the rotor 10 a ring of Arretierungsaugen 17, which extend to just before the inner surface of the rotor bell 10. Your locking holes 18 are smooth-walled or threaded at 19. In the smooth-walled locking holes 18 locking pins 20 are inserted for transport, which correspond with corresponding locking holes 21 in the rotor bell 10. At least one - better two or more - the locking eyes 17 has threaded holes 19 for screwing locking screws 22, with which the transport position can be fixed immovably. For accurate depth positioning while maintaining the necessary distance of the rotor bell 10 from the stator support member 8, a spacer sleeve 23 is inserted before screwing the locking screws 22.

Bei der Montage des Motors 7 im Heimatwerk wird also nach dem Komplettieren des Ständertragteils 8 mit den Blechpaketen 14 und Wicklungen 13 und nach dem Komplettieren des Läufers 10 mit den magnetisierbaren Polen 15 die Läuferglocke flach auf das Ständertragteil gelegt und die Arretierposition gesucht. Gegebenenfalls wird diese Position nun schon mit den Arretierstiften 20 an den glattwandigen Löchern 18 gesichert. Dann werden die Distanzhülsen 23 in diejenigen Löcher der Läuferglocke gesteckt, deren korrespondierende Gewindelöcher 19 unter ihnen liegen. Schließlich werden Arretierschrauben 22 in die Distanzhülsen 23 geführt und in den Gewindelöchern 19 verschraubt. Damit ist der Motor bereit zur Prüfung und zur Lieferung.When assembling the motor 7 in the Heimatwerk so after completion of the stator support member 8 with the laminated cores 14 and windings 13 and after completing the rotor 10 with the magnetizable poles 15, the rotor bell placed flat on the stator support member and searched the locking position. If necessary, this position is already secured with the locking pins 20 on the smooth-walled holes 18. Then the spacers 23 are inserted into those holes of the rotor bell whose corresponding threaded holes 19 are below them. Finally, locking screws 22 are guided in the spacers 23 and screwed into the threaded holes 19. This makes the engine ready for testing and delivery.

Im Herstellerwerk für Waschmaschinen wird die Läuferglocke dieses Motors 7 an den Gewindestumpf 24 des Wellenzapfens 4 angesetzt, aufgeschraubt und auf nicht dargestellte Weise mittels einer Schraube in der Position gesichert, in der das Ständertragteil 8 auf den Befestigungsaugen 6 des Tragsterns 1 anliegt. Dann werden die Befestigungslöcher 25 im Ständertragteil 8 mit den Befestigungsaugen 6 zur Dekkung gebracht und Befestigungsschrauben 26 eingedreht. Als Zugang zu den Befestigungsschrauben 26 dienen die Bearbeitungsöffnungen 27 in der Läuferglokke 10. Danach werden Arretierstifte 20 und Arretierschrauben 22 ausgedreht und die Distanzhülsen 23 entnommen. Arretierstifte 20 und -schrauben 22 sowie die Distanzhülsen 23 können als Rücklauftelle an das Motorenwerk zurückgesandt werden.In the manufacturing plant for washing machines, the rotor bell of this motor 7 is attached to the threaded stub 24 of the shaft journal 4, screwed and secured in a manner not shown by means of a screw in the position in which the stator support member 8 rests on the attachment eyes 6 of the support star 1. Then the mounting holes 25 are brought in the stator support member 8 with the attachment eyes 6 for Dekkung and screwed fastening screws 26. As access to the mounting screws 26 serve the machining openings 27 in the Läuferglokke 10. Thereafter, locking pins 20 and locking screws 22 are turned off and removed the spacers 23. Locking pins 20 and screws 22 and the Spacers 23 can be returned as return point to the engine plant.

Der Grundaufbau des Motors gemäß Fig. 3 und 4 und seiner Verbindung mit dem Tragstern ähnelt dem der Fig.1 und 2. Das Ständertragteil 8 gemäß Fig. 1 und 2 entfällt bzw. wird vom Blechpaket 28 gebildet; das aus einzelnen ringförmigen Blechlamellen zusammensetzt ist.

Zwischen dem Blechpaket 28 und dem Tragstern 1 ist am Blechpaket außerdem noch ein tellerförmiger Ring 32 angebracht, der ebenfalls aus Blech oder aus Kunststoff bestehen kann. Er dient als Schutz vor dem Eindringen von Staub, der vor allem als magnetisierbarer Staub den ordnungsgemäßen Betrieb des Motors 30 erheblich beeinträchtigen kann. Dazu bildet der Ring 32 zusammen mit dem Rand 16 der Läuferglocke 10 eine labyrinthartige Dichtung 11. Auf der Innenseite des Ringraumes für die Erregerwicklungen 13 und die Pole 15 wird eine solche Labyrinthdichtung 33 von einer innenkante des Blechpaketes 28 zusammen mit einem umlaufenden Kragen 34 an der Innenseite der Läuferglocke 10 gebildetThe basic structure of the motor according to FIGS. 3 and 4 and its connection to the carrier star is similar to that of FIGS. 1 and 2. The stator carrier 8 according to FIGS. 1 and 2 is omitted or formed by the laminated core 28; which is composed of individual annular laminations. The laminated core also extends further into the center of rotation than the laminated core 14 of the motor 7 in Fig. 1 and 2, because on a center closer to the center of rotation, the laminated core is provided with mounting holes 29, by means of which the motor 30 on the fastening eyes 31 of the supporting star 1 can be mounted by screws 26. Between the laminated core 28 and the supporting star 1 is also a plate-shaped ring 32 is attached to the laminated core also attached, which may also consist of sheet metal or plastic. It serves as protection against the ingress of dust, which can significantly affect the proper operation of the engine 30, especially as a magnetizable dust. On the inside of the annulus for the field windings 13 and the poles 15, such a labyrinth seal 33 from an inner edge of the laminated core 28 together with a peripheral collar 34 on the Inside the rotor bell 10 is formed

Die Befestigungslöcher 29 dienen nicht nur zur Befestigung des Motors 30 am Tragstern 1 sondern auch zur Festlegung der Motorenteile (Ständer und Läufer) zueinander vor dem Einbau des Motors 30. Dazu sind die Befestigungslöcher 29 oder ein Teil von ihnen mit Innengewinde versehen. Sein Kerndurchmesser ist dabei mindestens so groß wie der Nenndurchmesser der Befestigungsschrauben 26. Der Nenndurchmesser des Innengewindes entspricht aber genau dem von Arretierschrauben 35, mit denen die Motorenteile festgelegt werden. Dazu sind ferner in die Bearbeitungsöffnungen 36 für den Zugang zu den Befestigungsschrauben 26 Distanzhülsen 37 eingesetzt, die zwischen der Läuferglocke 10 und dem Blechpaket 28 einen definierten Abstand halten, wenn die Arretierschrauben 35 in das Gewinde der Befestigungslöcher 29 eingeschraubt sind. Anstelle dieser Maßabhängigkeiten zwischen den Durchmessern der Befestigunglöcher und den jeweiligen Schrauben, können ein Teil der Löcher dieses Kreises ausschließlich als Befestigungslöcher 29 und ein anderer Teil als Arretierlöcher dienen. Diese beiden Arten von Löchern können zur leichteren Unterscheidung auch auf Kreisen mit unterschiedlichen Radien liegen. Dann können die Löcher in der Läuferglocke 10 auch unterschiedliche Durchmesser aufweisen, z.B. die Bearbeitungslöcher 36 einen größeren Durchmesser als die für die Distanzhülsen 37 vorgesehene Löcher.The mounting holes 29 are not only used to attach the motor 30 to the star carrier 1 but also to fix the engine parts (stator and rotor) to each other before installing the motor 30. For this purpose, the mounting holes 29 or a part of them are provided with internal thread. Its core diameter is at least as large as the nominal diameter of the mounting screws 26. The nominal diameter of the internal thread but corresponds exactly to that of locking screws 35 with which the engine parts are determined. For this purpose, 26 spacers 37 are further used in the processing openings 36 for access to the fastening screws, which hold a defined distance between the rotor bell 10 and the laminated core 28 when the locking screws 35 are screwed into the thread of the mounting holes 29. Instead of these Maßabhängigkeiten between the diameters of the mounting holes and the respective screws, a part of the holes of this circle can serve only as mounting holes 29 and another part as locking holes. These two types of holes can also be located on circles with different radii for easier identification. Then, the holes in the rotor bell 10 may also have different diameters, e.g. the machining holes 36 have a larger diameter than that provided for the spacers 37 holes.

Der Einbau des Motors 30 im Herstellerwerk für Waschmaschinen gestaltet sich ähnlich einfach wie beim Beispiel der Fig. 1 und 2. Die Läuferglocke 10 wird zunächst auf den Gewindestumpf 24 aufgeschraubt, bis die Außenfläche des Rings 32 auf den Befestigungsaugen 31 zur Anlage kommt. Dann wird diese Position im Verhältnis zum Wellenzapfen 4 gesichert (Schraube o. ä.). Falls die Befestigungslöcher von den Arretierlöchern verschieden sind, werden nun erst die Befestigungsschrauben 26 durch die Bearbeitungslöcher 36 hindurch in die Befestigungsaugen 31 gedreht. Dann werden die Arretierschrauben 36 und die Distanzhülsen 37 entfernt und an den Hersteller des Motors zurückgegeben. Falls die Befestigungslöcher und die Arretierlöcher gleich gestaltet sind, werden nur einige, z. B. drei; der Löcher zur Arretierung mittels der Distanzhülsen 37 und der Arretierschrauben 35 benutzt sein. Dann kann ebenso verfahren werden wie vorstehend. Sind allerdings alle dieser Löcher, z.B. mehr als drei, zur Arretierung benutzt worden, dann muß man bei der Montage schrittweise vorgehen, d.h. zuerst wird eine Arretierschraube 35 und die zugeordnete Distanzhülse 37 entfernt und dort eine Befestigungsschraube 26 eingeführt und festgeschraubt. Dann geht man mit den übrigen Löchern schrittweise gleichermaßen vor.The installation of the motor 30 in the factory for washing machines designed similarly simple as in the example of FIGS. 1 and 2. The rotor bell 10 is first screwed onto the threaded stub 24 until the outer surface of the ring 32 comes to rest on the fixing eyes 31. Then this position is secured in relation to the shaft journal 4 (screw o. Ä.). If the fastening holes are different from the locking holes, only the fastening screws 26 are now rotated through the machining holes 36 into the fastening eyes 31. Then the locking screws 36 and the spacers 37 are removed and returned to the manufacturer of the engine. If the mounting holes and the locking holes are the same, only some, z. Three; the holes used for locking by means of the spacers 37 and the locking screws 35. Then can be proceeded as above. However, if all of these holes, for example more than three, have been used for locking, then one must proceed step by step during installation, ie first a locking screw 35 and the associated spacer sleeve 37 are removed and there a fastening screw 26 is inserted and screwed tight. Then you proceed stepwise with the other holes.

Alle vorgestellten Beispiel der erfindungsgemäßen Antriebsvorrichtung haben noch einen wesentlichen Vorteil gemeinsam: Gegenüber bisherigen bekannten Vorschlägen kommen sie mit weniger bzw. kleineren Wälzlagern für den Wellenzapfen 4 aus.All presented example of the drive device according to the invention still have a significant advantage in common: Compared with previous known proposals they come with fewer or smaller bearings for the shaft journal 4.
