Die Erfindung geht aus von einer Lageraufnahme nach der Gattung des Anspruchs 1.The invention is based on a bearing recording according to the preamble of claim 1.

Aus der US-PS 5,661,357 ist schon eine Lageraufnahme für ein Kalottenlager bekannt, die das Kalottenlager ohne weitere Hilfsmittel umfasst. Die Lageraufnahme ist mit einem Aussengehäuse einer elektrischen Maschine einteilig. Das Gehäuse ist aus Kunststoff. Ein Aussengehäuse aus Metall mit einer solchen integrierten Lageraufnahme ist schwierig herzustellen. Oft wird ein Lagerschild, das die Lageraufnahme enthält, als magnetisches Rückschlusselement benötigt und muss deshalb aus Metall sein.From US Pat. No. 5,661,357 a bearing holder for a spherical bearing is already known, which comprises the spherical bearing without further aids. The bearing holder is in one piece with an outer housing of an electrical machine. The housing is made of plastic. An outer housing made of metal with such an integrated bearing holder is difficult to manufacture. A bearing plate that contains the bearing holder is often required as a magnetic yoke element and must therefore be made of metal.

Die DE 198 39 640 AI zeigt eine Lageraufnahme für ein Kalottenlager, die das Lager so umfasst, dass keine weiteren Befestigungs- oder Halteelemente benötigt werden. Die Lageraufnahme hat jedoch kein Axialanlauf.DE 198 39 640 AI shows a bearing holder for a spherical bearing, which includes the bearing so that no further fastening or holding elements are required.

The bearing mount also has no axial run-up.

Die FR 78 22850 AI zeigt ein Kalottenlager, das durch ein Sicherungsring in einer Lageraufnahme gehalten wird. Dies erhöht die Anzahl der zu montierenden Teile.The FR 78 22850 AI shows a spherical bearing that is held in a bearing seat by a locking ring. This increases the number of parts to be assembled.

Die DE 195 08 306 AI bzw. US-PS 5,886,437 zeigt, wie eine Feder benutzt wird um das axiale Spiel einer Rotorwelle zu reduzieren.DE 195 08 306 AI or US Pat. No. 5,886,437 shows how a spring is used to reduce the axial play of a rotor shaft.

Die DE 195 13 970 AI zeigt ein Gleitlager, das ein freies Ende einer Rotorwelle umschließt, und an dem eine Feder integriert ist, die das axiale Spiel der Rotorwelle reduziert. Das Gleitlager wird aber nicht von einer Lageraufnahme in seiner axialen Position gehalten.DE 195 13 970 AI shows a plain bearing, which encloses a free end of a rotor shaft, and on which a spring is integrated, which reduces the axial play of the rotor shaft. The plain bearing is not held in its axial position by a bearing seat.

Die Lageraufnahme 1 umgreift das Kalottenlager 5 so, dass das Kalottenlager 5 formschlüssig in der Lageraufnahme 1 gehalten ist. Diese Kalottenlagerhalterung 7 desThe bearing holder 1 engages around the spherical bearing 5 so that the spherical bearing 5 is held in the bearing holder 1 in a form-fitting manner. This spherical bearing holder 7 of

Kalottenlagers 5 ist integral mit der Lageraufnahme 1 ausgeführt, z.B. einteilig in einem Kunststoffspritzvorgang hergestellt.Spherical bearing 5 is integral with the bearing holder 1, e.g. made in one piece in a plastic injection molding process.

Weiterhin hat die Lageraufnahme 1 ein Axialanlauf 8, an der ein freies Ende der Rotorwelle 6 anliegt. Die LageraufnahmeFurthermore, the bearing holder 1 has an axial run-up 8, against which a free end of the rotor shaft 6 bears. The inventory

1 ist in einer Aufnahme 10 eines Gehäuses 9 eingepresst, wobei der Axialanlauf 8 nicht notwendigerweise an dem1 is pressed into a receptacle 10 of a housing 9, the axial run-up 8 not necessarily on the

Gehäuse 9 anliegen muss. Der Axialanlauf 8 ist integral mit der Lageraufnahme 1 ausgeführt.Housing 9 must fit. The axial run-up 8 is carried out integrally with the bearing seat 1.

Das Gehäuse 9 ist beispielsweise das Gehäuse einer elektrischen Maschine, die unter anderem einen Stator 11 und einen Rotor 13 mit einer Mittelachse 14 aufweist. Das Gehäuse 9 ist beispielsweise aus Metall und dient als magnetisches Rückschlusselement für den Stator 11.The housing 9 is, for example, the housing of an electrical machine, which includes a stator 11 and has a rotor 13 with a central axis 14. The housing 9 is made of metal, for example, and serves as a magnetic yoke element for the stator 11.

Die Lageraufnahme 1 weist zwei unter einem stumpfen Winkel aufeinanderzulaufende Gleitflächen 18 auf, an denen sich das Kalottenlager 5 an seinem Umfang abgestützt und so gegenüber der Mittelachse 14 schwenkbar ist. An einer dem Axialanlauf 8 abgewandten Stirnfläche 19 des Kalottenlagers 5 greift mindestens ein Vorsprung 7, der beispielsweise federnd ausgebildet ist, zur axialen Sicherung und Halterung des Kalottenlagers 5 in der Lageraufnahme 1 an.The bearing receptacle 1 has two sliding surfaces 18 which run towards one another at an obtuse angle, on which the spherical bearing 5 is supported on its circumference and can thus be pivoted with respect to the central axis 14. On an end face 19 of the spherical bearing 5 facing away from the axial run-up 8, at least one projection 7, which is, for example, resilient, engages for axially securing and holding the spherical bearing 5 in the bearing receptacle 1.

Die Erfindung ist aber nicht beschränkt ' auf Kalottenlager 5, sondern auch für andere Gleitlager mit integrierter Lagerhalterung und Axialanlauf.However, the invention is not limited to spherical bearing 5, but also for other plain bearings with an integrated bearing holder and axial run-up.

Figur 2a zeigt eine erfindungsgemäße Lageraufnahme 1, mit einem elastischen Federelement 15, das an der Lageraufnahme 1, dem Kalottenlagers 5 abgewandt, angeordnet ist. Das elastische Federelement 15 kann mit der Lageraufnahme 1 einteilig oder auch zweiteilig sein, wenn das elastische Federelement 15 aus einem anderen Material, wie z.B. Gummi besteht. Das elastische Federelement 15 kann auch in Form einer Spiralfeder oder Blattfeder ausgebildet sein. Die Lageraufnahme 1 hat zumindest einen Vorsprung 7, der in diesem Ausführungsbeispiele als Clipshaken ausgeführt ist und das Kalottenlager 5 umfasst.Figure 2a shows a bearing holder 1 according to the invention, with an elastic spring element 15 which is arranged on the bearing holder 1, facing away from the spherical bearing 5. The elastic spring element 15 can be in one piece with the bearing receptacle 1 or also in two parts if the elastic spring element 15 is made of a different material, e.g. Rubber is made. The elastic spring element 15 can also be designed in the form of a spiral spring or leaf spring. The bearing holder 1 has at least one projection 7, which in this exemplary embodiment is designed as a clip hook and comprises the spherical bearing 5.

Die Lageraufnahme 1 gemäß Figur 2a wird wiederum in die Aufnahme 10 des Gehäuses 9 eingeführt, wie es in Figur 2b gezeigt ist. Dabei stößt ein freies Ende 17 des elastischen Federelements 15 an einen Gehäuseboden 20 des Gehäuses 9 in der Aufnahme 10 an und übt so eine Federkraft in axialer Richtung, d.h. parallel zur Mittelachse 14, gegen das freie Ende der Rotorwelle 6 aus . Dadurch wird das axiale Spiel der Rotorwelle 6 reduziert. The bearing holder 1 according to FIG. 2a is again inserted into the holder 10 of the housing 9, as shown in FIG. 2b. A free end 17 of the elastic spring element 15 abuts a housing base 20 of the housing 9 in the receptacle 10 and thus exerts a spring force in the axial direction, ie parallel to the central axis 14, against the free one End of the rotor shaft 6. The axial play of the rotor shaft 6 is thereby reduced.
