Abstract
Description
Die zur Abstützung von drehenden Wellen benötigten Radial- und Axialkräfte schwanken in weiten Bereichen. Die Abstützung einer rotierenden Welle, unter Verwendung von Gleitlagern wird üblicherweise derart gelöst, daß Radial- und Axialgleitlager, einseitig oder doppelt wirkend, getrennt oder als kombinierte Lager angeordnet werden. Die axiale Tragfähigkeit solcher Lager wird, in bekannter Weise, durch Kippsegmentlager oder Axiallagern mit Keil- und Rastflächen gewährleistet. Der Fertigungsaufwand für die Axialgleitlager, bedingt durch die geometrischen Verhältnisse im einen Fall, und durch die große Anzahl an Konstruktionselementen im anderen Fall, ist beträchtlich.The radial and axial forces required to support rotating shafts fluctuate in wide areas. The support of a rotating shaft, using Plain bearings are usually solved in such a way that radial and axial plain bearings, one-sided or double acting, separated or arranged as a combined bearing. The axial Load capacity of such bearings is, in a known manner, by tilting segment bearings or Axial bearings with wedge and locking surfaces guaranteed. The manufacturing effort for the Axial plain bearing, due to the geometric conditions in one case, and by large number of construction elements in the other case is considerable.
Es ist bekannt, daß beim Radial-Axialbundlager auf eine gesonderte Versorgung des Axiallagers mit Schmierstoff verzichtet werden kann. Das Axiallager ist zur Erlangung einer Tragfähigkeit auf die Ausnutzung des im Radiallager erzeugten Druckes angewiesen.It is known that in the radial thrust collar bearing on a separate supply of the Thrust bearings with lubricant can be dispensed with. The thrust bearing is available a load capacity depends on the utilization of the pressure generated in the radial bearing.
Die Erfindung stellt sich die Aufgabe einen in der Herstellung, im Vergleich zu den oben beschriebenen Lagern, wesentlich günstigeren Axiallagerteil zu schaffen, der direkt mit einem Radiallager beliebiger Innenkontur kombiniert werden kann, und der die durchaus begrenzte Belastbarkeit der Radial-Axialbundlager mit einfachen Mitteln steigert.The invention has as its object the manufacture compared to the above described bearings to create much cheaper thrust bearing part directly with a radial bearing of any inner contour can be combined, and it does Limited load capacity of radial axial thrust bearings increases with simple means.
Diese Aufgabenstellung wird erfindungsgemäß wie folgt gelöst:According to the invention, this task is solved as follows:
1. Ein Radialgleitlager, beliebiger Innenkontur, vorzugsweise geteilt ausgeführt, wird mit einem oder zwei Axiallagern kombiniert. Das Axialgleitlager wird im einfachsten Fall durch einen Bund gebildet dessen Achse um einen bestimmten Winkel zur Achse des Radiallagers gedreht ist. Dies geschieht erfindungsgemäß dadurch, daß die ursprünglich plan bearbeiteten, lotrecht zur Achse des Radiallagers ausgerichteten Anlaufbunde durch Verdrehen gegenüber dieser Achse während der Bearbeitung zu Keilsegmenten umgestaltet werden. Durch eine nicht lotrecht zu den Anlaufbunden ausgeführte Bohrung zur Herstellung des Radiallagers entstehen ebenfalls Keilsegmente.1. A radial slide bearing, any internal contour, preferably split, is carried out with one or two thrust bearings combined. The axial plain bearing is in the simplest case by a bundle formed its axis by a certain angle to the axis of the radial bearing is rotated. This happens according to the invention in that the originally plan processed starting collars aligned perpendicular to the axis of the radial bearing Rotation in relation to this axis has been transformed into wedge segments during machining will. Through a hole that is not perpendicular to the start collars Manufacture of the radial bearing also creates wedge segments.
Entsprechend der Segmentierung des Radiallagers können mehrere Axialgleitflächen am Umfang als Axiallager wirksam werden. Die Orientierung und die Anstellung der einzelnen Axialgleitflächen kann innerhalb eines Axialgleitlagers differieren. Ein einzelnes Segment wird durch eine einfache Bearbeitung der Stirnseite(n), unter einem Winkel zu der Achse des Radiallagers, zu einem Segment eines kombinierten Radial-Axialgleitlagers. Durch die Ausrichtung der einzelnen Segmente lassen sich kombinierte Radial-Axialgleitlager für beliebig wirksame Kraftrichtungen und beliebige Drehrichtungen anpassen.Depending on the segmentation of the radial bearing, several axial sliding surfaces can be on Scope to be effective as a thrust bearing. The orientation and employment of the individual Axial sliding surfaces can differ within an axial sliding bearing. A single segment is done by simply machining the face (s) at an angle to the axis of the radial bearing, to a segment of a combined radial / axial slide bearing. Through the Alignment of the individual segments can be combined radial-axial sliding bearings for Adapt any effective direction of force and any direction of rotation.
Die Schmierstoffzufuhr in das, oder die Axialgleitlager erfolgt mittels aus dem Radiallager verdrängten Schmierstoffes. Die Keilwirkung der Bunde läßt das Axialgleitlager tragfähig werden, wobei der erhöhte Druck des ins Axiallager zugeführten viskosen Mediums in günstiger Weise ausgenützt wird (Fig. 1).The lubricant is fed into the or the axial sliding bearing by means of lubricant displaced from the radial bearing. The wedge effect of the bundles makes the axial plain bearing load-bearing, the increased pressure of the viscous medium fed into the axial bearing being used in a favorable manner ( FIG. 1).
2. Eine Behinderung des Abflusses des Schmierstoffes aus dem Axiallager wird durch eine kegelige Vorbearbeitung der Anlaufbunde erreicht. Bei der Fertigung der Keilflächen wird die Punktberührung zwischen Welle und Keilfläche des Axiallagers dadurch ganz oder teilweise kompensiert (Fig. 2).2. An obstruction of the outflow of the lubricant from the axial bearing is achieved by a tapered pre-processing of the thrust collars. During the manufacture of the wedge surfaces, the point contact between the shaft and the wedge surface of the axial bearing is compensated for in whole or in part ( FIG. 2).
3. Eine besondere Variante sieht die Ausbildung der Axialflächen als Gewindesegment vor. Dabei ergibt sich ein in Umfangsrichtung konvergierender, oder divergierender Spalt konstanter Höhe auf der Innen- und Außenseite des Axiallagersegments. Besonders günstig ist die Ausführung mit einer zulässigen Winkelabweichung von ±50 in Breitenrichtung des Axiallagers zur Beeinflussung des Abflusses aus dem Axiallager.3. A special variant provides for the formation of the axial surfaces as a thread segment. This results in a gap that converges or diverges in the circumferential direction constant height on the inside and outside of the thrust bearing segment. Very cheap is the version with a permissible angular deviation of ± 50 in the width direction of the Thrust bearings to influence the outflow from the thrust bearing.
Der besondere Wert dieser Erfindung liegt im Verzicht auf eine eigene Schmierstoffversorgung der Axiallager. Durch die Teilung im Radialgleitlager kann die Fertigung der Axiallagersegmente, im Vergleich zu beschriebenen, dem Stand der Technik entsprechenden Konstruktionen, deutlich vereinfacht werden.The particular value of this invention lies in the fact that it does not have its own Lubricant supply to the axial bearings. Due to the division in the radial slide bearing, the Production of the thrust bearing segments, compared to the described, the prior art corresponding constructions can be significantly simplified.
