Elektromotor, insbesondere feuchtigkeitsdicht geschlossener Kommutatormotor zum Antrieb einer axial angeflanschten Hvdraulikpumpe.Electric motor, in particular a moisture-tight commutator motor for driving an axially flanged hydraulic pump.
Die Neuerung betrifft einen Elektromotor, insbesondere einen feuchtigkeitsdicht geschlossenen Kommutatormotor zum Antrieb einer axial angeflanschtenThe innovation concerns an electric motor, in particular a moisture-tight commutator motor for driving an axially flanged
Hydraulikpumpe der im Oberbegriff des Schutzanspruchs 1 angegebenen Art.Hydraulic pump of the type specified in the preamble of claim 1.
Durch die EP 0 472 746 Al ist bereits ein Elektromotor bekannt, bei dem aus der durch ein Lagerschild abgeschlossenen Stirnseite eines topfförmigen Motorgehäuses die Rotorwelle mit einem Exzenterwellenende herausrägt, das die Stößel einer angeflanschten Hydraulikpumpe antreibt. In dem Lagerschild ist außerdem eine getrennte Tragplatte fur Bürsten vorgesehen, die mit dem am Antrieb vorgesehenen Kommutator in bekannter Weise zusammenwirken. Aufgrund der vielen Einzelteile ist der Montageaufwand bei diesem bekannten Elektromotor noch recht aufwendig.An electric motor is already known from EP 0 472 746 A1 in which the rotor shaft with an eccentric shaft end protrudes from the front side of a pot-shaped motor housing, which is closed off by a bearing shield. This drives the tappets of a flanged hydraulic pump. The bearing shield also has a separate support plate for brushes, which interact with the commutator provided on the drive in a known manner. Due to the many individual parts, the assembly work for this known electric motor is still quite complex.
Der Neuerung liegt nun die Aufgabe zugrunde, einen Elektromotor zum Antrieb einer Hydraulikpumpe hinsichtlich Fertigungs- und Montageaufwand noch weiter zu vereinfachen und zu verbilligen. Diese Aufgabe wird durch die im Schutzanspruch 1 gekennzeichneten Merkmale gelöst.The innovation is based on the task of further simplifying and reducing the cost of manufacturing and assembly of an electric motor for driving a hydraulic pump. This task is solved by the features identified in claim 1.
Der an dem Getriebegehäuse der Hydraulikpumpe angeflanschte Elektromotor hat kein Lagerschild mehr, welches das Motorgehäuse feuchtigkeitsdicht abschließt und das zweite Kugellager trägt. Neuerungsgemäß übernimmt die Bürstentragplatte die Dichtungsfunktion zwischen dem Motor- und dem Getriebegehäuse. Außerdem dient die Bürstentragplatte gleichzeitig als Zentrierelement für das auf der Motorwelle befestigte zweite Lager. Hiermit ist in diesem Montagezustand bereits eine Prüfung des Elektromotors gegeben. Auch kann der Elektromotor in diesem Vormontagezustand sicher transportiertThe electric motor flanged to the gearbox housing of the hydraulic pump no longer has a bearing plate, which seals the motor housing against moisture and carries the second ball bearing. According to the innovation, the brush support plate takes over the sealing function between the motor and gearbox housing. In addition, the brush support plate also serves as a centering element for the second bearing attached to the motor shaft. This means that the electric motor can already be tested in this assembled state. The electric motor can also be transported safely in this pre-assembled state.

werden. Durch Wegfall des Lagerschildes wird eine billige und leicht zu montierende Einheit von einem Elektromotor für eine Hydraulikpumpe geschaffen.By eliminating the bearing plate, a cheap and easy-to-assemble unit of an electric motor for a hydraulic pump is created.
Weitere vorteilhafte Ausgestaltungen des Neuerungsgegenstandes sind den weiteren Unteransprüchen zu entnehmen.Further advantageous embodiments of the subject matter of the innovation can be found in the further subclaims.
Die Neuerung wird anhand eines Ausfuhrungsbeispiels im folgenden näher beschrieben. Es zeigen:The innovation is described in more detail below using an example. It shows:
Fig 1 einen axialen Teilschnitt von einem Kommutatormotor mit einem angeflanschten Getriebegehäuse undFig. 1 shows an axial partial section of a commutator motor with a flanged gear housing and
Fig 2 ein Einzelheit aus Fig. 1.Fig 2 a detail from Fig. 1.
Die Fig. 1 zeigt einen Elektromotor, insbesondere einen geschlossenen,
feuchtikeitsdichten Kommutatormotor 1 mit einem topfförmigen Motorgehäuse
3, dessen zylindrisches Mantelteil 5 auf der Innenseite 7 mit Dauermagneten 9,
11 versehen ist. In dem Motorgehäuse 3 ist eine Rotorwelle 13 mit einem darauf
befestigten Rotorblechpaket 15 angeordnet, das eine an einem Kommutator 17
angeschlossene Rotorwicklung 19 aufnimmt. Der Kommutator 17 steht mit
durch Federn 21, 23 beaufschlagten Bürsten 25, 27 in Kontaktverbindung, welche in Gehäusen 29, 31 geführt sind. Diese Führungsgehäuse 29, 31 sind mit
einer Bürstentragplatte 33 fest verbunden und bestehen z. B. aus Messing. Das Motorgehäuse 3 ist an einer Stirnfläche 35 eines Getriebegehäuses 37 einer
nicht näher dargestellten Hydraulikpumpe angeflanscht angeordnet, wobei zwischen den Stirnflächen des Motorgehäuses 3 und des Getriebegehäuses 37
ein Flachdichtelement angeordnet ist. Die Rotorwelle 13 ist einerseits auf einem
ersten Lager 39 im Inneren des Motorgehäuses 3 und andererseits auf einem zweiten Lager 41 gelagert, welches ein Wälzlager mit einem Außenring 43 und
einem Innenring 45 ist. Das erste Lager 39 ist gemäß Fig, I ein durch eine
Klemmbrille 89 gehaltenes Gleitlager, aber im Rahmen der Neuerung kann dieses Lager auch aus einem Wälzlager bestehen.
Das Wälzlager 41 ist ein abgedichtetes Lager, welches ein Eindringen vonFig. 1 shows an electric motor, in particular a closed, moisture-proof commutator motor 1 with a pot-shaped motor housing 3, the cylindrical casing part 5 of which is provided with permanent magnets 9, 11 on the inner side 7. A rotor shaft 13 with a rotor laminated core 15 fastened thereto is arranged in the motor housing 3, which accommodates a rotor winding 19 connected to a commutator 17. The commutator 17 is in contact with brushes 25, 27 acted upon by springs 21, 23, which are guided in housings 29, 31. These guide housings 29, 31 are firmly connected to a brush support plate 33 and are made of brass, for example. The motor housing 3 is flanged to an end face 35 of a gear housing 37 of a hydraulic pump (not shown in detail), with a flat sealing element arranged between the end faces of the motor housing 3 and the gear housing 37. The rotor shaft 13 is supported on the one hand on a first bearing 39 inside the motor housing 3 and on the other hand on a second bearing 41, which is a roller bearing with an outer ring 43 and an inner ring 45. The first bearing 39 is, according to Fig. 1, a plain bearing held by a clamping bracket 89, but within the scope of the innovation this bearing can also consist of a roller bearing.
The rolling bearing 41 is a sealed bearing which prevents the ingress of
-3--3-
Flüssigkeiten in das Lager und damit in das Innere des Motorgehäuses 3 verhindert.Liquids from entering the bearing and thus the interior of the motor housing 3 are prevented.
Die Rotorwelle 13 ragt mit ihrem verlagerten Exzenterende 91 in das Getriebegehäuse 37 hinein, das über nicht dargestellte Pumpstößel der Hydraulikpumpe z. B. ein Kraftfahrzeug-Antiblockiersystem antreibt.The rotor shaft 13 projects with its displaced eccentric end 91 into the gear housing 37, which drives, for example, a motor vehicle anti-lock braking system via pump tappets of the hydraulic pump (not shown).
Neuerungsgemäß ist das Flachdichtungselement zwischen den Stirnflächen des Motorgehäuses 3 und des Getriebegehäuses 37 die aus einem Isolierwerkstoff bestehende Bürstentragplatte 33 für die mit dem Kommutator 17 zusammenwirkenden Bürsten 25, 27. Diese Bürstentragplatte dient gleichzeitig als Zentrierelement für das auf der Rotorwelle 13 fest angeordnete zweite Lager 41 und ist als Deckel mit dem Motorgehäuse 3 fest verbunden. Das topfformige Motorgehäuse 3 ist in seiner zylindrischen Öfrhungsumrandung 47 mit einer abgestuften Paßfläche 49 zur feuchtigkeitsdichten Anlage der an ihrem Außenrand mit einem zylindrischen Flanschteil 51 entsprechend ausgebildeten, scheibenförmigen Bürstenplatte 33 versehen. Weiterhin weist die in die Öffnung des Motorgehäuses 3 formschlüssig eindrückbare Bürstentragplatte 33 an dem äußeren Rand 53 ihrer inneren Stirnfläche 55 mehrere federnde Rasthaken 57 auf, dessen Rastzähne 59 hinter durch Metallverformungen des Motorgehäuses 3 gebildete Rastkanten 62 verrastbar sind; Diese Metallverformungen können aus durchgedrückten Butzen 63 in dem Motorgehäuse 3 oder auch aus teilweise ausgestanzten, biegbaren Lappen bestehen. Durch die oberen Merkmale wird eine einfache Montage der Bürstentragplatte 33 mit dem Motorgehäuse 3 geschaffen, wobei gleichzeitig eine sichere Verrastung der Bürstentragplatte mit dem Motorgehäuse 3 und eine exakte Vorzentrierung der Rotorwelle 13 in dem Motorgehäuse 3 geschaffen werden. Hiermit erhält man bereits einen vormontierten Elektromotor 1 für eine Hydraulikpumpe, der in diesem Zustand bereits voll prüfbar und auch transportfähig ist.According to the innovation, the flat sealing element between the end faces of the motor housing 3 and the gear housing 37 is the brush support plate 33, made of an insulating material, for the brushes 25, 27 that interact with the commutator 17. This brush support plate also serves as a centering element for the second bearing 41 that is fixedly arranged on the rotor shaft 13 and is firmly connected to the motor housing 3 as a cover. The pot-shaped motor housing 3 is provided in its cylindrical opening border 47 with a stepped fitting surface 49 for the moisture-tight attachment of the disk-shaped brush plate 33, which is correspondingly designed on its outer edge with a cylindrical flange part 51. Furthermore, the brush support plate 33, which can be pressed into the opening of the motor housing 3 in a form-fitting manner, has several spring-loaded locking hooks 57 on the outer edge 53 of its inner end face 55, the locking teeth 59 of which can be locked behind locking edges 62 formed by metal deformations of the motor housing 3; these metal deformations can consist of pressed-through slugs 63 in the motor housing 3 or of partially punched-out, flexible tabs. The above features enable the brush support plate 33 to be easily assembled with the motor housing 3, while at the same time ensuring that the brush support plate is securely locked with the motor housing 3 and that the rotor shaft 13 is precisely pre-centered in the motor housing 3. This provides a pre-assembled electric motor 1 for a hydraulic pump, which in this state can already be fully tested and transported.
Gemäß Fig. 1 ist zumindest das zweite Lager 41 ein abgedichtetes Wälzlager, dessen Außenring 43 einerseits in einer Zentriersausnehmung 65 in der äußerenAccording to Fig. 1, at least the second bearing 41 is a sealed roller bearing, the outer ring 43 of which is on the one hand in a centering recess 65 in the outer
