(Patent application file number: P 43 20 005.2).
Bei der in der Hauptanmeldung beschriebenen elektrischen Maschine hat es sich gezeigt, daß zur sicheren Befestigung des wellenseitigen Festlagers im Gehäuse des Aufnahmekör pers sehr enge Passungstoleranzen eingehalten werden müs sen, die zu unterschiedlichen Montagekräften führen. Als weiterer Nachteil sind die fehlenden Fixierhilfen zur exak ten Positionierung des Festlagers im Gehäuse zu nennen, da mit die erforderliche Einbautiefe der Welle im Aufnahmekör per eingehalten werden kann.With the electrical described in the main application Machine has shown that for secure attachment the shaft-side fixed bearing in the housing of the receiving body pers very tight fit tolerances must be observed that lead to different assembly forces. When Another disadvantage is the lack of fixing aids for the exact ten positioning of the fixed bearing in the housing, because with the required installation depth of the shaft in the holder can be complied with.
Daher liegt der Erfindung die Aufgabe zugrunde, eine elek trische Maschine der eingangs genannten Gattung derart wei ter zu entwickeln, daß unter Umgehung der vorgenannten Nachteile eine präzise, leicht einzustellende und zu mon tierende Wellenlagerung ermöglicht wird. Therefore, the invention has for its object an elek trical machine of the type mentioned in such a white ter develop that bypassing the aforementioned Disadvantages a precise, easy to set and mon shaft bearing is made possible.
Diese Aufgabe wird erfindungsgemäß durch die kennzeichnen den Merkmale des Patentanspruchs 1 gelöst, wonach die Trä gerplatte eine Öffnung aufweist, deren Innendurchmesser kleiner ist als der Außendurchmesser des zweiten Lagers und wobei die Trägerplatte zwischen dem zweiten Lager und dem Ständer angeordnet ist.According to the invention, this object is characterized by the solved the features of claim 1, according to which the Trä gerplatte has an opening whose inner diameter is smaller than the outer diameter of the second bearing and the carrier plate between the second bearing and the Stand is arranged.
Durch die in den Unteransprüchen aufgezeigten Maßnahmen sind zweckmäßige Ausbildungen der Erfindung angegeben, die im Zusammenhang mit den weiteren Merkmalen und Vorteilen der Erfindung nachfolgend anhand einer Zeichnung näher dar gestellt und erläutert werden.By the measures indicated in the subclaims expedient developments of the invention are given, the in connection with the other features and advantages the invention with reference to a drawing be put and explained.
Die Fig. 1 zeigt zur Verdeutlichung des Erfindungsgedan kens im vergrößerten Maßstab einen im Querschnitt darge stellten Elektromotor, dessen den Ständer 3 bildendes Ge häuse an einem Aufnahmekörper 2 angeflanscht ist. Im Auf nahmekörper 2 sind eine doppelflutige Radialkolbenpumpe und elektrohydraulische Ventile zum Betrieb einer schlupfgere gelten Bremsanlage untergebracht, die in der gewählten Schnittdarstellung nicht explizit zu erkennen sind. Zwischen dem Aufnahmekörper 2 und dem als Gehäusetopf aus geformten Ständer 3 befindet sich eine Trägerplatte 4, die zur Aufnahme von Schleifbürsten und elektrischen Anschluß komponenten geeignet ist. Die Trägerplatte 4 ist zum Zwecke der Abdichtung des Ständers 3 gegenüber dem Aufnahmekörper 2 mit Dichtungen 17 versehen, die die Trägerplatte 4 gegen über dem Aufnahmekörper 2 und dem Gehäuse des Ständers 3 abdichten. Die Dichtungen 17 sind entweder in die Träger platte 4 eingespritzt oder eingelegt. Das topfförmige Ge häuse des Ständers 3 ist in der gezeigten Ausführungsform als Dünnblech-Tiefziehteil ausgeführt und bildet eine dich te Schutzkappe sowie den Magnetkreis, wobei die Magnete 18 im Ständer 3 entweder eingelegt oder eingeklebt sind. Der Ständer 3 wird mittels Halteschrauben, die gleichfalls durch die Trägerplatte 4 reichen am Aufnahmekörper 2 ange flanscht. Eine formschlüssige Befestigung des Ständers 3 am Aufnahmekörper 2 ist gleichfalls denkbar. Zur Erleichterung der Montage werden die Magnete 18 erst nach dem Anflanschen des Elektromotors am Aufnahmekörper 2 magnetisiert. Der Läu fer wird zum Zwecke der Betriebsbereitstellung zunächst mit der Trägerplatte (4), dem Kugellager (Lager 7), der Distanzscheibe 12 und dem Nadellager 19 versehen. Das Lager 7 und Nadellager 19 weisen auf der Welle 1 bzw. Exzenter 20 einen Preßsitz auf. Das Führungslager (Lager 5) weist einen Preßsitz in dem Sackloch 6 auf, so daß das Lager 5 die Funktion des Loslagers übernimmt und das Lager 7 das Fest lager bildet. Die vormontierte Läufereinheit kann somit un ter der Wirkung geringer Fügekräfte in die Bohrungsstufe 16 eingesteckt werden, wobei die Distanzscheibe 12 weitgehend vollflächig an der Bohrungsstufe 16 sowie am äußeren Lager ring 11 anliegt. Der äußere Lagerring 11 stützt sich gleichzeitig an einer ringförmigen Ausnehmung 10 in der Trägerplatte 4 ab. Die Ausnehmung 10 und der Bund 15 bilden eine Montage- und Fixiereinrichtung für das Lager 7 und für den Gehäusetopf des Ständers 3, der mit den Magneten 18 über den Läufer gestülpt und angeschraubt wird. Der über wiegende Teil der Lagerkräfte wird durch das Kugellager (Lager 7) aufgenommen. Nachdem die aus dem Lager 7, dem Na dellager 19, der Distanzscheibe 12 und der Trägerplatte 4 bestehende Baugruppe des Läufers als vormontierte Einheit in die Stufenbohrung 13 im Aufnahmekörper 2 eingeschoben und mit den Halteschrauben befestigt ist, wird als Verdreh sicherung des äußeren Lagerrings 11 des Lagers 7 in die Stufenbohrung 13 Klebstoffmasse gespritzt. Dies geschieht über eine den Aufnahmekörper 2 bis zur Stufenbohrung 13 durchdringende Bohrung 14, 50 daß der Lagerring 11 infolge der aufgetragenen Klebstoffmasse sicher befestigt ist. Durch diese Befestigungsmaßnahme kann der Durchmesser der Stufenbohrung 13 großzügig toleriert werden, wobei geringe Einpreßkräfte für das Lager 7 möglich sind. Die gewünschte Position des Lagers 7 sowie die Befestigung der weiteren mit der Welle 1 verbundenen Bauteile ist durch die als Mon tage- und Fixiereinrichtung wirksame Trägerplatte 4 und die Distanzscheibe 12 gewährleistet. Fig. 1 shows to illustrate the Invention kens on an enlarged scale a cross-section Darge presented electric motor, the stand 3 forming Ge housing is flanged to a receiving body 2 . On body 2 , a double-flow radial piston pump and electrohydraulic valves for operating a more slip-resistant brake system are housed, which are not explicitly recognizable in the selected sectional view. Between the receiving body 2 and the housing cup made of molded stand 3 there is a carrier plate 4 , which is suitable for receiving brushes and electrical connection components. The carrier plate 4 is provided for the purpose of sealing the stator 3 with respect to the receiving body 2 with seals 17 , which seal the carrier plate 4 against the receiving body 2 and the housing of the stator 3 . The seals 17 are either injected into the carrier plate 4 or inserted. The cup-shaped Ge housing of the stand 3 is designed in the embodiment shown as a thin sheet deep-drawn part and forms a protective cap and the magnetic circuit, the magnets 18 in the stand 3 either being inserted or glued. The stand 3 is flanged by means of retaining screws, which also extend through the carrier plate 4 on the receiving body 2 . A form-fitting attachment of the stand 3 to the receiving body 2 is also conceivable. To facilitate assembly, the magnets 18 are magnetized only after the electric motor is flanged onto the receiving body 2 . The Läu fer is first provided with the carrier plate ( 4 ), the ball bearing (bearing 7 ), the spacer 12 and the needle bearing 19 for the purpose of operational readiness. The bearing 7 and needle bearing 19 have an interference fit on the shaft 1 or eccentric 20 . The guide bearing (bearing 5 ) has an interference fit in the blind hole 6 , so that the bearing 5 takes over the function of the floating bearing and the bearing 7 forms the fixed bearing. The preassembled rotor unit can thus be inserted into the bore step 16 under the action of low joining forces, the spacer 12 resting largely over the entire area on the bore step 16 and on the outer bearing ring 11 . The outer bearing ring 11 is supported at the same time on an annular recess 10 in the carrier plate 4 . The recess 10 and the collar 15 form a mounting and fixing device for the bearing 7 and for the housing pot of the stand 3 , which is put over the rotor and screwed with the magnets 18 . The predominant part of the bearing forces is absorbed by the ball bearing (bearing 7 ). After the existing from the bearing 7 , the Na dellager 19 , the spacer 12 and the support plate 4 assembly of the rotor as a pre-assembled unit in the stepped bore 13 in the receiving body 2 and fastened with the retaining screws, the outer bearing ring 11 is secured as a twist Bearing 7 injected into the stepped bore 13 adhesive compound. This is done via a bore 14 , 50 penetrating the receiving body 2 up to the stepped bore 13 such that the bearing ring 11 is securely fastened as a result of the applied adhesive composition. This fastening measure allows the diameter of the stepped bore 13 to be tolerated generously, with low press-in forces being possible for the bearing 7 . The desired position of the bearing 7 and the attachment of the other components connected to the shaft 1 is ensured by the carrier plate 4 effective as a mounting and fixing device and the spacer 12 .
