Description

Vor allem bei kleinen elektrischen Maschinen kommen mit Vorteil kalottenförmige Gleitlager zur Anwendung, da diese infolge ihrer Selbsteinstellung in Achsrichtung auch bei nicht ganz eindeutiger axialer Ausrichtung der Bohrungen eine einwandfreie Lagerung der Wellen ermöglichen. Die Lagerkalotten werden dabei mit ihren Außenenden gegen den Lagerdeckel abgestützt, während sie am Innenende durch eine federnde Halterung gehalten werden, die die Selbsteinstellung der Lagerkalotte nicht behindert, im übrigen aber eine Abstützung in axialer Richtung bildet.Dome-shaped ones are particularly advantageous for small electrical machines Plain bearings are used because they are self-adjusting in the axial direction even if the axial alignment of the bores is not entirely clear, it is flawless Enable storage of the shafts. The bearing domes are thereby with their outer ends supported against the bearing cap, while at the inner end by a resilient bracket are held, which does not hinder the self-adjustment of the bearing dome, im but the rest forms a support in the axial direction.

Die Erfindung bezieht sich auf eine Vorrichtung zur federnden Halterung dieser Art und besteht im wesentlichen darin, daß das die Lagerkalotte am Innenende derselben axial abstützende federnde Halteglied seinerseits durch einen Gewindering einstellbar abgestützt ist. Gegenüber den bisherigen federnden Halterungen hat die erfindungsgemäße Vorrichtung den Vorteil, daß die die Lagerkalotte in axialer Richtung abstützende Federkraft einstellbar ist und daß auf diese Weise die bei der Fertigung auftretenden Toleranzen eindeutig beherrscht werden können.The invention relates to a device for resilient mounting of this type and consists essentially in the fact that the bearing dome at the inner end the same axially supporting resilient holding member in turn by a threaded ring adjustable is supported. Compared to the previous resilient brackets, the The inventive device has the advantage that the bearing cap in the axial direction supporting spring force is adjustable and that in this way the during manufacture occurring tolerances can be clearly controlled.

Bei einer bevorzugten Ausführungsform der Erfindung ist der Lagerdeckel mit einer Buchse versehen, die die Lagerkalotte vom Außenende derselben aus umfaßt, wobei das Innenende der Buchse das Gewinde zur Aufnahme des Gewinderinges aufweist. Bei einer solchen Ausführung der Erfindung werden die einzelnen Lagerbauteile durch den Gewindering zu einem Einbauteil zusammengefaßt, das als Ganzes auf Lager gehalten und als Ganzes in die Bohrung des Lagerschildes eingesetzt werden kann.In a preferred embodiment of the invention, the bearing cap is provided with a bush which surrounds the bearing dome from the outer end thereof, wherein the inner end of the socket has the thread for receiving the threaded ring. In such an embodiment of the invention, the individual bearing components are through the threaded ring combined into a component that is kept in stock as a whole and can be used as a whole in the bore of the end shield.

Die Zeichnung zeigt ein Beispiel für die letzterwähnte Ausführungsform in einem Längsschnitt. Es bezeichnen Io den Lagerdeckel, II die zu lagernde Welle, I2 die Lagerkalotte, I3 den Abstützkegel des Lagerdeckels Io, I4 einen Zwischenring aus Filz od. dgl., I5 die Haltefeder, I6 eine die Lagerkalotte I2 vom Außenrand derselben umfassende Buchse des Lagerdeckels Io und I7 den am Innenrand dieser Buchse I6 in ein Gewinde derselben eingesetzten Gewindering.The drawing shows an example of the last-mentioned embodiment in a longitudinal section. Io denotes the bearing cover, II the shaft to be supported, I2 the bearing cap, I3 the support cone of the bearing cap Io, I4 an intermediate ring Made of felt or the like, I5 the retaining spring, I6 a bearing dome I2 from the outer edge the same comprehensive socket of the bearing cover Io and I7 on the inner edge of this socket I6 threaded ring inserted into a thread of the same.

Die Zeichnung läßt erkennen, daß die scheibenförmig gestaltete Haltefeder I5 sich einerseits mit einem entsprechend der Außenfläche der Lagerkalotte I2 abgebogenen Innenrand gegen das Innenende der Lagerkalotte I2 legt und sich andererseits mit ihrem Außenrand gegen den Gewindering I7 abstützt. Durch mehr oder weniger weites Eindrehen des Gewinderinges 17 hat man es so in der Hand, die in axialer Richtung abstützende Federkraft der Haltefeder I5 einzustellen. Etwaige Fertigungstoleranzen der Haltefeder I5 sowie der Lagerkalotte I2 können auf diese Weise bequem ausgeglichen werden.The drawing shows that the disk-shaped retaining spring I5 is bent on the one hand with a corresponding to the outer surface of the bearing dome I2 Inner edge against the inner end of the bearing cap I2 and on the other hand with its outer edge is supported against the threaded ring I7. By more or less far Screwing in the threaded ring 17 has it in the hand in the axial direction set the supporting spring force of the retaining spring I5. Any manufacturing tolerances the retaining spring I5 and the bearing cap I2 can easily be balanced in this way will.
