WälzlagereinheitRolling bearing unit

Die Erfindung bezieht sich auf eine Wälzlagereinheit für elektrische Maschinen.The invention relates to a rolling bearing unit for electrical machines.

Aufgabe ist es, eine kompakte, leicht wechselbare und wartungsarme Wälzlagerung für elektrische Maschinen zu schaffen.The task is to create a compact, easily replaceable and low-maintenance rolling bearing for electrical machines.

Die Aufgabe wird gelöst durch die Kombination der im Kennzeichen des Hauptanspruches enthaltenen Merkmale.The problem is solved by the combination of the features contained in the characterising part of the main claim.

Diese werden nachfolgend an dem in der Zeichnung dargestellten Beispiel beschrieben.These are described below using the example shown in the drawing.

Die einzige Figur zeigt den teilweisen Längsschnitt einer Wälzlagereinheit für elektrische Maschinen.The single figure shows the partial longitudinal section of a rolling bearing unit for electrical machines.

Ein Zylinderrollenlager ist mit einem Außenring 1 und einem Innenring 2 aus Stahl und Rollen 3 aus Keramik versehen. Der Außenring 1 ist in zwei identische spiegelbildlich angeordnete Flanschhälften 4 über nur angedeutete Toleranzhülsen (16) eingesetzt. Ringförmige, radial äußere Schenkelabschnitte 5 sind mit am Umfang verteilten Durchgangsbohrungen 6 versehen und über Schraubbolzen 7 befestigt. Wie aus der Figur im einzelnen nicht hervorgeht, sind zwischen den Durchgangsbohrungen 6 weitere am Umfang verteilte Schrauben vorgesehen, die lediglich die Flanschhälften 4 miteinander verbinden, um bereits im nicht eingebauten Zustand eine kompakte Einheit zu bilden. Dadurch ist der Außenring 1 fest eingespannt und positioniert. Radial nach innen gerichtete, ringförmige Schenkelabschnitte 8 lassen zu den Seitenflächen des Zylinderrollenlagers einen weiten Abstand und damit einen großen Ringraum 9 fürA cylindrical roller bearing is provided with an outer ring 1 and an inner ring 2 made of steel and rollers 3 made of ceramic. The outer ring 1 is inserted into two identical, mirror-imaged flange halves 4 via tolerance sleeves (16) that are only indicated. Ring-shaped, radially outer leg sections 5 are provided with through holes 6 distributed around the circumference and are fastened using screw bolts 7. As is not shown in detail in the figure, further screws distributed around the circumference are provided between the through holes 6, which only connect the flange halves 4 to one another in order to form a compact unit even when not installed. The outer ring 1 is thus firmly clamped and positioned. Ring-shaped leg sections 8 directed radially inwards leave a large distance to the side surfaces of the cylindrical roller bearing and thus a large annular space 9 for

Schmiermittel. Der Innenring 2 ist beiderseits mit Wellenabstandsringen 10 versehen, die axial bis unter die radial inneren Schenkelabschnitte 8 reichen und mit denen Spaltdichtungen 11 bilden. Sie sind durch bohrungsseitig eingesetzte Klammerhülsen 12 mit dem Innenring 2 fest verbunden.Lubricant. The inner ring 2 is provided on both sides with shaft spacer rings 10, which extend axially to below the radially inner leg sections 8 and with which form gap seals 11. They are firmly connected to the inner ring 2 by clamp sleeves 12 inserted on the bore side.

Die Wellenabstandsringe (10) sind mit hinter die Ringabschnitte (8) greifenden Flanschringen (17) versehen, um die Wellenabstandsringe (10) gegen Herausfallen im nicht eingebauten Zustand zu hindern. Sie bilden mit ihren axialen Spalten zur entsprechenden Stirnseite der Ringabschnitte (8) zusätzliche Dichtungen.The shaft spacer rings (10) are provided with flange rings (17) that engage behind the ring sections (8) in order to prevent the shaft spacer rings (10) from falling out when not installed. With their axial gaps, they form additional seals on the corresponding end face of the ring sections (8).

Einer der Wellenabstandsringe 10 ist als Impulsring ausgebildet und arbeitet mit einem in die linke Flanschhälfte 4 eingesetzten Sensor 13 zusammen. Durch die Rollen 3 aus Keramik ist der Rotor mit Welle 14 gegenüber dem Stator bzw. dem Motorgehäuse 15 elektrisch isoliert. Alternativ können auch mit Isolierschichten versehene Rollen, Laufringe oder Flanschhälften verwendet werden.One of the shaft spacer rings 10 is designed as a pulse ring and works together with a sensor 13 inserted into the left flange half 4. The ceramic rollers 3 electrically insulate the rotor with shaft 14 from the stator or the motor housing 15. Alternatively, rollers, races or flange halves provided with insulating layers can also be used.

Die Wälzlagereinheit bildet somit ein fertig montiertes, kompaktes Wechselteil und kann über die Schraubbolzen 7 am skizzierten Lagerschild 15 des Motors befestigt und einfach auf die angedeutete Welle 14 aufgezogen werden.The rolling bearing unit thus forms a fully assembled, compact interchangeable part and can be attached to the sketched bearing plate 15 of the motor using the screw bolts 7 and simply pushed onto the indicated shaft 14.
