Description

Die Erfindung behandelt die Wälzlageranordnung für die Motorwelle einer Vertikal-Flächenschleifmaschine, bei welcher die Größe des radialen bzw. axialen Lagerspiels getrennt geregelt werden kann. Derartige Lagerungen gehören zum Stand der Technik. Bisher bekanntgewordene Ausführungen sind derart ausgebildet, daß eine Festbüchse zwischen den Axialdrucklagern im Lagerschild befestigt ist. Damit muß zwangläufig die Mutter zur Einstellung des axialen Spiels auf der Welle angeordnet werden.The invention deals with the roller bearing assembly for the motor shaft a vertical surface grinding machine, in which the size of the radial or axial Bearing play can be regulated separately. Such bearings are part of the stand of the technique. So far known designs are designed such that a Fixed bushing is attached between the thrust bearings in the end shield. So must inevitably arranged the nut to adjust the axial play on the shaft will.

Legt man den Wellenbund zwischen das Radiallager und das Axialdrucklager, so kommt die Mutter zur Einstellung des Axialspiels ins Motorinnere zu liegen. Eine Nachstellung des Axialspiels ist nur bei demontiertem Motor möglich. Außerdem muß beim Auswechseln der Axialdrucklager das Läuferpaket von der Welle abgepreßt werden.If the shaft collar is placed between the radial bearing and the axial thrust bearing, so the nut comes to rest inside the motor to adjust the axial play. One Adjustment of the axial play is only possible when the motor is dismantled. Also must When replacing the thrust bearing, the rotor core is pressed off the shaft.

Legt man den Wellenbund ins Motorinnere, so kommt die Mutter zur Einstellung des Axialspiels zwischen das Radiallager und die Axialdrucklager zu liegen. Auch in diesem Falle ist eine Nachstellung des Axialspiels nur bei demontiertem Motor möglich.If you put the shaft collar inside the motor, the nut will adjust of the axial play to lie between the radial bearing and the thrust bearing. Even In this case, the axial play can only be readjusted when the motor is dismantled possible.

Demgegenüber gestaltet sich die Ausführung nach der Erfindung sehr einfach. Die Festbüchse ist mit ihrem Mittelflansch in bekannter Weise zwischen den Axialdrucklagern auf der Welle angeordnet. Sie wird in diesem Falle zwecks genaueren Rundlaufes mit der Welle zusammen überschliffen. Die Einstellung der Axialluft erfolgt durch einen Gewindering, welcher außerhalb des Motors an der Stirnseite des Lagerschildes angeordnet ist. Die Einstellung der Radialluft erfolgt durch eine Mutter, welche ebenfalls außerhalb des Motors auf der Welle angeordnet ist. Beide Teile, der Gewindering als auch die Mutter, sind nach Abschrauben einer als Labyrinthdichtung ausgebildeten Gegenmutter frei zugänglich. Eine Nachstellung sowohl der Axialluft als auch der Radialluft der Lagerung ist bei vollständig montiertem Motor jederzeit möglich, auch kann die gesamte Lagerung erneuert werden, ohne das Läuferpaket von der Welle abzupressen, wodurch sich gegenüber den bekannten Ausführungen ein erheblicher Vorteil ergibt.In contrast, the embodiment according to the invention is very much simple. The fixed sleeve is with its central flange in a known manner between the thrust bearings arranged on the shaft. In this case it will be used for the purpose of being more precise Run out together with the shaft. The axial clearance is set by a threaded ring, which is outside the motor on the face of the end shield is arranged. The radial clearance is set by a nut, which is also arranged outside the motor on the shaft. Both parts, the threaded ring as well as the nut are designed as a labyrinth seal after unscrewing one Lock nut freely accessible. A readjustment of both the axial clearance and the Radial clearance of the bearing is possible at any time when the motor is fully assembled, the entire bearing can also be replaced without removing the rotor core from the shaft to be pressed off, which is a significant advantage over the known designs results.

In der Zeichnung ist ein Längsschnitt durch die Wälzeranordnung für die Motorwelle einer Vertikal-Flächenschleifmaschine als Ausführungsbeispiel des Erfindungsgegenstandes dargestellt.In the drawing is a longitudinal section through the tome arrangement for the motor shaft of a vertical surface grinding machine as an embodiment of the Subject of the invention shown.

Die Festbüchse i ist zwischen den Axialdrucklagern 3 und 4 auf der Motorwelle 2 angeordnet. Dieselbe wird durch die beiden Nutmuttern 6 und 7, die oberhalb des Radiallagers 5 liegen, festgehalten.The fixed sleeve i is between the thrust bearings 3 and 4 on the Motor shaft 2 arranged. The same is achieved by the two locknuts 6 and 7, the above the radial bearing 5 are held.

Zur Einstellung der Axialluft dient der Gewindering 9 und zur Einstellung der Radialluft die Mutter Io, welche beide nach Entfernung der als Labyrinthdichtung ausgebildeten Gegenmutter II, welche in das Lagerschild 8 eingreift, leicht zugänglich sind.The threaded ring 9 is used to adjust the axial clearance and for adjustment the radial air the nut Io, which both after removal of the labyrinth seal trained lock nut II, which engages in the end shield 8, easily accessible are.
