Abstract

The proposal is for a motor-pump assembly consisting of an electric motor (1) and a pump (2). The shaft (30) carries both the armature (26) of the electric motor and the eccentric (31) of the pump. The shaft is essentially supported by two pump bearings (6, 11) fitted on either side of the eccentric in the pump housing (3). To ensure that the third, motor bearing (25) is aligned with the two pump bearings, the motor housing is movably fitted above the pump housing. As, however, the first pump bearing (6) is secured to the end plate (21) before the electric motor is fitted, it is proposed that the holder have a clearance A such that the first pump bearing is unlosably secured to the end plate (21) before assembly. After assembly, i.e. when the first pump bearing is inserted into the corresponding recess in the pump housing (3), the end plate can be sufficiently moved to align the bearing with the pump bearing (6). The order of magnitude of the clearance is between 0.5 and 1 mm.

Description

Die Erfindung bezieht sich auf Elektromotor-/Pumpenaggregat mit einer Welle, die sowohl den Anker des Elektromotors als auch den Exzenter der Pumpe trägt, wobei die Welle in zwei Pumpenlager, die im Pumpengehäuse angeordnet sind, und von einem dritten Lager, daß im Motorgehäuse gehalten ist, getra­ gen wird, und mit Befestigungsmittel, um das Gehäuse des Elek­ tromotors am Pumpengehäuse zu befestigen.The invention relates to an electric motor / pump unit with a shaft that both the armature of the electric motor as also carries the eccentric of the pump, the shaft in two Pump bearings, which are arranged in the pump housing, and from a third bearing that is held in the motor housing gen, and with fasteners to the housing of the Elek to attach the tromotors to the pump housing.

Ein derartiges Motor-/Pumpenaggregat ist z. B. in der DE 43 15 826 A1 beschrieben. Gemäß der Beschreibung, wird es in einer hydraulischen Bremsanlage eingesetzt.Such a motor / pump unit is e.g. B. in DE 43 15th 826 A1. According to the description, it will be in a hydraulic brake system used.

Das Pumpengehäuse besteht aus einem einstückigen Block, in dem neben den Pumpenkolben auch Ventile vorgesehen sind, mit deren Hilfe eine Druckmodulation in den Radbremsen der Bremsanlage erfolgen kann. Der Block weist eine dreistufige Sackbohrung auf, in die die Motorwelle hineinragt. In die zweite Stufe der Sackbohrung münden senkrecht Bohrungen ein, in denen die Pum­ penkolben geführt sind. Die erste und dritte Stufe dienen der Aufnahme der Pumpenlager.The pump housing consists of a one-piece block in which In addition to the pump pistons, valves are also provided, with their Help a pressure modulation in the wheel brakes of the brake system can be done. The block has a three-stage blind hole into which the motor shaft protrudes. In the second stage of Blind holes open vertically in which the pump are guided. The first and third stages serve the Inclusion of the pump bearings.

Da diese Aufnahmen in einem einstückigen Block ausgebildet sind, sind die Pumpenlager nahezu exakt zueinander fluchtend ausgerichtet, d. h. sie sind weder gegeneinander verkantet noch gegeneinander versetzt. Damit ist auch die Lage der Welle ex­ akt definiert. Es bereitet nun gewisse Schwierigkeiten, daß dritte Lager, das am Gehäuse des Elektromotors ausgebildet ist, zur Welle hin auszurichten. Because these shots are formed in a one-piece block the pump bearings are almost exactly aligned aligned, d. H. they are neither tilted against each other nor offset against each other. The position of the shaft is also ex act defined. It is now causing certain difficulties that third bearing, which is formed on the housing of the electric motor is to align to the wave.  

Um ein Fluchten aller drei Lager zu erzielen, wird vorgeschla­ gen, daß die Befestigungsmittel derart ausgebildet sind, daß das Elektromotorgehäuse vor der endgültigen Montage gegenüber dem Pumpengehäuse ausgerichtet werden kann.To achieve an alignment of all three camps, it is suggested conditions that the fasteners are designed such that the electric motor housing opposite the final assembly can be aligned with the pump housing.

Um dieses Ausrichten auch dann bewerkstelligen zu können, wenn eines der Pumpenlager vor der Montage des Elektromotors an einem Schild des Elektromotors ohne Spiel gehalten wird (wie im Stand der Technik aufgezeigt), wird vorgeschlagen, diese Halterung mit einem Spiel zu versehen. Dies ermöglicht es, den Elektromotor vor der Befestigung am Pumpengehäuse durch Aus­ nutzung des Spiels noch auszurichten. Gleichzeitig wird das Spiel nur so groß gewählt, daß das Pumpenlager vor der Montage sicher am Schild gehalten werden kann.In order to be able to do this even if one of the pump bearings before installing the electric motor a shield of the electric motor is held without play (like shown in the prior art), it is proposed To provide bracket with a game. This enables the Electric motor before attachment to the pump housing by off Align use of the game. At the same time it will Game chosen only so large that the pump bearing before assembly can be held securely on the sign.

Das Schild besteht aus einer Kunststoffkappe, die in das topf­ förmige Motorgehäuse eingesteckt wird und damit nicht mehr radial gegenüber dem Elektromotor verschoben werden kann. Die­ ses Schild verfügt an seiner äußeren Stirnseite über eine durch einen Ring begrenzte Vertiefung, in dem das erste Pum­ penlager über eine Teillänge eingesteckt und verliersicher gehalten ist. Vor der Montage des Elektromotors auf das Pum­ pengehäuse wird somit die Welle vom Motorlager sowie vom er­ sten Pumpenlager gehalten.The shield consists of a plastic cap that is placed in the pot shaped motor housing is inserted and therefore no longer can be moved radially relative to the electric motor. The This shield has one on its outer face recess delimited by a ring in which the first pump Pen bearing inserted over a partial length and captive is held. Before installing the electric motor on the pump pen housing is thus the shaft of the engine mount and he Most pump bearings held.

Zur Montage wird die Welle in das Pumpengehäuse eingeführt, wobei das erste Pumpenlager in die erste Aufnehmung im Pumpen­ gehäuse paßgenau eingeführt wird. Die im Betrieb auftretenden Kräfte werden dann nicht mehr vom Lagerschild sondern vom Pum­ pengehäuse aufgenommen.The shaft is inserted into the pump housing for assembly, wherein the first pump bearing in the first receptacle in the pumping housing is inserted with a precise fit. The occurring in the company Forces are then no longer from the end shield but from the pump pen housing added.

Da gemäß dem Stand der Technik die Halterung des ersten Pum­ penlagers im Lagerschild paßgenau war, war bei dieser Montage automatisch die Lage des Elektromotorgehäuses zum Pumpengehäu­ se festgelegt. Damit diese Lage mit der gewollten überein­ stimmte, mußten alle Teile mit hoher Genauigkeit gefertigt werden oder aber eine gewisse Verspannung zwischen den drei Lagern hingenommen werden.Since according to the prior art, the holder of the first pump pen bearing in the bearing plate was a perfect fit during this assembly  automatically the position of the electric motor housing to the pump housing se set. So that this location coincides with the intended one all parts had to be manufactured with high accuracy or some tension between the three Camps are accepted.

Es wird vorgeschlagen, daß die Halterung des ersten Pumpen­ lagers im Lagerschild des Elektromotors mit einem Spiel er­ folgt. Dieses Spiel wird so gewählt, daß die Haltekräfte noch ausreichend groß sind, um das Lager vor der Montage veliersi­ cher zu halten, andererseits eine Verschiebung des Lager­ schilds und damit des ganzen Elektromotorgehäuses gegenüber dem im Pumpengehäuse fixierten ersten Pumpenlager zu ermögli­ chen.It is proposed that the bracket of the first pump bearing in the end shield of the electric motor with a game follows. This game is chosen so that the holding forces are still are sufficiently large to veliersi the bearing before assembly cher hold, on the other hand a shift of the camp shields and thus of the entire electric motor housing to enable the first pump bearing fixed in the pump housing chen.

Die Erfindung wird im folgenden anhand eines Ausführungsbei­ spiels näher erläutert.The invention is illustrated below with the aid of an embodiment explained in more detail.

Das Motor-Pumpenaggregat besteht aus einem Elektromotor 1 so­ wie einer Pumpe 2. Die Pumpe besteht aus einem Pumpengehäuse 3, das in diesem Ausführungsbeispiel aus einem Aluminiumblock gebildet wird.The motor-pump assembly consists of an electric motor 1 and a pump 2 . The pump consists of a pump housing 3 , which is formed from an aluminum block in this embodiment.

Von einer Seitenfläche dieses Gehäuses aus beginnend erstreckt sich eine dreistufige Sackbohrung 4. Die erste Stufe 5 mit dem größten Durchmesser trägt ein erstes Pumpenlager 6, in die zweite Stufe 7 mit einem etwas kleineren Durchmesser, münden seitlich Bohrungen ein, die die Pumpenkolben 8, 9 führen. In der tiefsten Stufe 10 mit dem kleinsten Durchmesser ist ein zweites Pumpenlager 11 gehalten.A three-stage blind bore 4 extends from one side surface of this housing. The first stage 5 with the largest diameter carries a first pump bearing 6 , in the second stage 7 with a somewhat smaller diameter, holes open laterally which guide the pump pistons 8, 9 . A second pump bearing 11 is held in the deepest stage 10 with the smallest diameter.

Der Elektromotor 1 besteht aus einem tiefgezogenen topfförmi­ gen Gehäuse 20, daß zum Pumpengehäuse 3 hin offen ist. Diese Seite wird durch ein Lagerschild 21 verschlossen, das in die offene Seite des Gehäuses 20 derart eingesteckt ist, daß es radial keine Beweglichkeit mehr aufweist. Das Lagerschild 21 dient gleichzeitig als Trageplatte für die Bürsten 22, wobei Zuleitungen 23 zu den Bürsten in dem aus Kunststoff her­ gestellten Lagerschild 21 eingebettet sind.The electric motor 1 consists of a thermoformed topfförmi housing 20 that the pump housing 3 is open. This side is closed by a bearing plate 21 which is inserted into the open side of the housing 20 in such a way that it no longer has any radial mobility. The bearing plate 21 serves as a supporting plate for the brush 22, wherein supply lines are embedded in the brush 23 to the plastic bearing plate provided forth 21st

Der Boden des Gehäuses 20 weist eine im Zentrum gelegene Ver­ tiefung auf, die ein weiteres Läger, nämlich das Motorlager 25, trägt. Die Welle 30 trägt sowohl den Anker 26 des Motors als auch ein Exzenter 31, der sich nach der Montage des Elek­ tromotors auf das Pumpengehäuse 3 in Höhe der zweiten Stufe 7 im Pumpengehäuse 3 befindet. Auf der Welle 30 befindet sich auch der Kommutator 27. An der Innenwand des topfförmigen Ge­ häuses 20 sind die Permanentmagnete 28 des Elektromotors be­ festigt.The bottom of the housing 20 has a Ver located in the center, which carries another bearing, namely the engine mount 25 . The shaft 30 carries both the armature 26 of the motor and an eccentric 31 , which is located on the pump housing 3 at the level of the second stage 7 in the pump housing 3 after the assembly of the electric motor. The commutator 27 is also located on the shaft 30 . On the inner wall of the cup-shaped housing 20 , the permanent magnets 28 of the electric motor are fastened.

Die Fig. zeigt das Motor-Pumpenaggregat im zusammengebauten Zustand. Die Welle 30 wird getragen von den beiden Pumpenla­ gern 6, 11, die die Radialkräfte beim Betrieb der Pumpe 2 in das Pumpengehäuse 3 einleiten.The figure shows the motor-pump unit in the assembled state. The shaft 30 is supported by the two Pumpenla like 6 , 11 , which introduce the radial forces in the operation of the pump 2 in the pump housing 3 .

Vor der Montage ist das erste Pumpenlager 6 an der Außenseite des Lagerschilds 21 gehalten, wobei dieses Lager und das Mo­ torlager 25 die Welle 30 halten. Die Halterung des ersten Pum­ penlagers erfolgt durch einen am Lagerschild 21 ausgebildeten Ring 32, in dem der Außenring des ersten Pumpenlagers über eine kurze Teillänge eingesteckt ist. Diese Halterung ist so ausgebildet, daß das Pumpenlager verliersicher gehalten wur­ de. Dazu wurde bisher der Außendurchmeser des Außenrings des ersten Pumpenlagers 6 genauso groß wie der Innendurchmesser des Rings 32 gewählt. Dies hatte zur Folge, daß das Gehäuse 20 des Elektromotors 1 nach der Montage, bei der das erste Pum­ penlager 6 im Pumpengehäuse fixiert wurde, auch gegenüber dem Pumpengehäuse ausgerichtet war.Before assembly, the first pump bearing 6 is held on the outside of the end shield 21 , this bearing and the motor bearing 25 holding the shaft 30 . The first pump bearing is held by a ring 32 formed on the end shield 21 , in which the outer ring of the first pump bearing is inserted over a short partial length. This bracket is designed so that the pump bearing was kept captive. For this purpose, the outer diameter of the outer ring of the first pump bearing 6 has hitherto been chosen to be the same size as the inner diameter of the ring 32 . This had the consequence that the housing 20 of the electric motor 1 after assembly, in which the first pump penlager 6 was fixed in the pump housing, was also aligned with the pump housing.

Da das Elektromotorgehäuse 20 nicht mit hoher Genauigkeit ge­ fertigt werden kann, konnte es sein, daß das Motorlager 25 am motorseitigen Ende der Welle nicht mit den im Pumpengehäuse 3 fixierten Pumpenlagern 6, 11 fluchtete.Since the electric motor housing 20 cannot be manufactured with high accuracy, it could be that the motor bearing 25 at the motor-side end of the shaft was not aligned with the pump bearings 6, 11 fixed in the pump housing 3 .

In dieser Ausführung wird daher ein Spiel zwischen dem Außen­ ring des Pumpenlagers 6 und dem Haltering 32 am Lagerschild 21 vorgesehen. Diese Toleranz ist mit A bezeichnet und liegt in der Größenordnung von 0,05 - 0,1 mm. Bei diesem Spiel wird das Lager vor der Montage des Elektromotors ausreichend fest am Lagerschild 21 gehalten, gleichzeitig kann sich aber das La­ gerschild 21, damit das Elektromotorgehäuse 20 und damit das Motorlager 25 radial zur Welle 30 ausrichten, so daß alle drei Lager, die die Welle 30 tragen, miteinander fluchten.In this embodiment, therefore, a game between the outer ring of the pump bearing 6 and the retaining ring 32 is provided on the end plate 21 . This tolerance is designated A and is in the order of 0.05-0.1 mm. In this game, the bearing before the assembly of the electric motor is adequately held on the bearing plate 21, at the same time but may be the La gerschild 21, so that the electric motor housing 20, and thus the engine mount 25 to align radially to the shaft 30 so that all three bearings, the Wear shaft 30 , align with each other.
