Description

Kippsegmente mit integrierter Feder  Tilting segments with an integrated spring
Die Erfindung betrifft ein Kippsegment nach dem Oberbegriff von Anspruch 1. The invention relates to a tilting segment according to the preamble of claim 1.
Aus dem Stand der Technik sind Kippsegmente für Gleitlager bekannt. Die Kippseg- mente weisen jeweils einen Grundkörper und eine oder mehrere Federn auf. Der Grundkörper und die Federn sind als separate Teile ausgeführt. Tilting segments for plain bearings are known from the prior art. The tilting segments each have a base body and one or more springs. The base body and the springs are designed as separate parts.
Bei der Montage eines herkömmlichen Kippsegments müssen der Grundkörper und die Feder zunächst miteinander verfügt werden. Wird das Kippsegment dann in das Trägerelement eingesetzt, besteht die Gefahr, dass die Feder verloren geht. When installing a conventional tilting segment, the base body and the spring must first be used together. If the tilting segment is then inserted into the carrier element, there is a risk that the spring will be lost.
Der Erfindung liegt die Aufgabe zugrunde, ein gegenüber den aus dem Stand der Technik bekannten Lösungen verbessertes Kippsegment verfügbar zu machen. Ins- besondere sollen die Herstellungskosten gesenkt und die Handhabbarkeit verbessert werden. The object of the invention is to make available a tilting segment which is improved compared to the solutions known from the prior art. In particular, the manufacturing costs are to be reduced and the manageability is to be improved.
Diese Aufgabe wird gelöst durch ein Kippsegment nach Anspruch 1. Bevorzugte Weiterbildungen sind in den Unteransprüchen enthalten. This object is achieved by a tilting segment according to claim 1. Preferred further developments are contained in the subclaims.
Ein Kippsegment ist ein Teil eines Gleitlagers, das dazu dient, eine erste Gleitfläche federnd abzustützen. Das Kippsegment selbst bildet einen Teil einer zweiten Gleitflä che, die relativ zu der ersten Gleitfläche um eine Drehachse des Gleitlagers drehbar ist. A tilting segment is part of a sliding bearing that serves to resiliently support a first sliding surface. The tilting segment itself forms part of a second Gleitflä surface, which is rotatable relative to the first sliding surface about an axis of rotation of the plain bearing.
Das Kippsegment weist einen Grundkörper und eine Feder auf. Die Feder ist zwi- schen dem Grundkörper und einem Trägerelement des Gleitlagers verspannt und übt eine zwischen dem Grundkörper und dem Trägerelement wirkende Federkraft aus. Die Federkraft ist orthogonal zu der ersten Gleitfläche und der zweiten Gleitfläche gerichtet. Somit wird der Grundkörper gegen die erste Gleitfläche verspannt. The tilting segment has a base body and a spring. The spring is clamped between the base body and a support element of the slide bearing and exerts a spring force acting between the base body and the support element. The spring force is directed orthogonally to the first sliding surface and the second sliding surface. The base body is thus braced against the first sliding surface.
Der Grundkörper ist entlang einer Wirkachse, die parallel zur Richtung der oben ge- nannten Federkraft verläuft, beweglich. Dadurch können Lageänderungen der beiden Gleitflächen relativ zueinander ausgeglichen werden, ohne dass es zu erhöhtem Verschleiß oder zu Beschädigungen des Gleitlagers kommt. The base body is movable along an active axis that runs parallel to the direction of the above-mentioned spring force. This can change the position of the two Sliding surfaces are balanced relative to each other, without causing increased wear or damage to the plain bearing.
Bei dem Gleitlager handelt es sich bevorzugt um ein Axialgleitlager. Hierbei verlaufen die erste Gleitfläche und die zweite Gleitfläche orthogonal zu der Drehachse des Gleitlagers. Die Federkraft der Feder des Kippsegments und damit auch die Wirk- achse des Kippsegments ist entsprechend parallel zu der Drehachse gerichtet. The plain bearing is preferably an axial plain bearing. Here, the first sliding surface and the second sliding surface are orthogonal to the axis of rotation of the sliding bearing. The spring force of the spring of the tilting segment and thus also the active axis of the tilting segment is directed parallel to the axis of rotation.
Erfindungsgemäß ist das Kippsegment einstückig ausgeführt. Dies bedeutet insbe- sondere, dass der Grundkörper und die Feder einstückig miteinander verbunden sind. According to the tilting segment is made in one piece. This means in particular that the base body and the spring are connected to one another in one piece.
Aufgrund der einstückigen Ausführung des erfindungsgemäßen Kippsegments müs- sen der Grundkörper und die Feder nicht in einem separaten Montageschritt verfügt werden. Zudem besteht keine Gefahr, dass die Feder verloren geht. Dies senkt die Kosten zur Herstellung des Kippsegments und vereinfacht die Montage. Due to the one-piece design of the tilting segment according to the invention, the base body and the spring do not have to be installed in a separate assembly step. In addition, there is no risk that the spring will be lost. This lowers the costs of producing the tilting segment and simplifies assembly.
In einer bevorzugten Weiterbildung ist das Kippsegment aus einem einzigen Rohteil gefertigt. Dies hat zur Folge, dass der Grundkörper und die Feder nahtlos, das heißt ohne Fügestelle, miteinander verbunden sind. Die Fertigung aus einem einzigen Rohteil ist besonders kosteneffizient. In a preferred development, the tilting segment is made from a single blank. The result of this is that the base body and the spring are connected to one another seamlessly, that is to say without a joint. Manufacturing from a single blank is particularly cost-effective.
In einer darüber hinaus bevorzugten Weiterbildung ist die Feder als Tellerfeder au s- gestaltet. Tellerfedern sind in der Norm DIN 2093 definiert. Es handelt sich um eine kegelige Ringschale, die in Achsrichtung belastbar ist. Eine Tellerfeder weist innen und außen eine kreisförmige Umrandung auf. In a further preferred development, the spring is designed as a plate spring. Disc springs are defined in the DIN 2093 standard. It is a conical ring shell that can be loaded in the axial direction. A disc spring has a circular border on the inside and outside.
In einer bevorzugten Weiterbildung ist die innere Umrandung mit dem Grundkörper verbunden, während die äußere Umrandung der Abstützung in dem Trägerelement dient. Dies bedeutet, dass die Feder sich ausgehend von der Verbindungsstelle zwi- schen der Feder und dem Grundkörper nach außen hin erstreckt und dort an dem Trägerelement anliegt. Anhand von Figuren werden im Folgenden eine aus dem Stand der Technik bekann- te Lösung und bevorzugte Ausführungsbeispiele der Erfindung erläutert. Überein- stimmende Bezugsziffern kennzeichnen dabei gleiche oder funktionsgleiche Merkma- le. Im Einzelnen zeigt: In a preferred development, the inner border is connected to the base body, while the outer border serves as a support in the carrier element. This means that the spring extends outwards from the connection point between the spring and the base body and rests there on the carrier element. A solution known from the prior art and preferred exemplary embodiments of the invention are explained below with reference to figures. Corresponding reference numerals identify identical or functionally identical features. In detail shows:

Ein in Fig. 1 dargestelltes Gleitlager 101 dient dazu, eine nicht dargestellte Welle aufzunehmen und drehbar zu lagern. Das Gleitlager 101 stützt die Welle in radialer und axialer Richtung. Zur Stützung der Welle in radialer Richtung weist das Gleitla ger 101 eine Radialgleitfläche 103 auf. Diese hat die Form einer Mantelfläche eines geraden Kreiszylinders. Zur Stützung der Welle in axialer Richtung dient eine Axial- gleitfläche. Diese wird durch mehrere Kippsegmente 105 gebildet. A slide bearing 101 shown in FIG. 1 serves to receive a shaft (not shown) and to mount it rotatably. The slide bearing 101 supports the shaft in the radial and axial directions. To support the shaft in the radial direction, the Gleitla ger 101 has a radial sliding surface 103. This has the shape of a lateral surface of a straight circular cylinder. An axial sliding surface serves to support the shaft in the axial direction. This is formed by a plurality of tilt segments 105.
Die Kippsegmente 105 werden von einem Träger 107 gehalten. Ihr Aufbau im Quer- schnitt ist in den Figuren 2 bis 6 im Detail dargestellt. The tilt segments 105 are held by a carrier 107. Their structure in cross section is shown in detail in FIGS. 2 to 6.
Die in den Figuren 2 bis 6 dargestellten Kippsegmente 105 bestehen jeweils aus ei- nem Grundkörper 201 und einer Feder 203. Die Kippsegmente 105 sind jeweils in eine Bohrung 205 des Trägers 107 eingelassen. Die Bohrungen 205 dienen der Fixierung des jeweiligen Kippsegments 105. Die Kippsegmente 105 und die Bohrun- gen 205 sind zu der Längsachse 207 rotationssymmetrisch. Innerhalb der Bohrung 205 ist das Kippsegment 105 entlang einer Längsachse 207, die einer Wegrichtung des Kippsegments 105 entspricht, beweglich. Eine entspre- chende Bewegung des Kippsegments 105 geht einher mit einer Spannung bzw. Ent- spannung der Feder 203. The tilt segments 105 shown in FIGS. 2 to 6 each consist of a base body 201 and a spring 203. The tilt segments 105 are each inserted into a bore 205 in the carrier 107. The bores 205 serve to fix the respective tilt segment 105. The tilt segments 105 and the bores 205 are rotationally symmetrical to the longitudinal axis 207. The tilting segment 105 is movable within the bore 205 along a longitudinal axis 207, which corresponds to a direction of travel of the tilting segment 105. A corresponding movement of the tilting segment 105 is accompanied by a tension or relaxation of the spring 203.
Das in Fig. 2 dargestellte Kippsegment 105 ist aus dem Stand der Technik bekannt. Der Grundkörper 201 und die Feder 203 sind hier als separate Stücke ausgeführt.The tilting segment 105 shown in FIG. 2 is known from the prior art. The base body 201 and the spring 203 are designed here as separate pieces.
Die Feder 203 wiederum ist zweistückig ausgeführt, das heißt, besteht aus zwei ein- zelnen Federn. Bei diesen Federn handelt es sich um herkömmliche Tellerfedern. The spring 203 is in turn made of two pieces, that is to say it consists of two individual springs. These springs are conventional disc springs.
Bei den in den Figuren 3 bis 6 dargestellten Kippsegmenten 105 handelt es sich um Ausführungsbeispiele der Erfindung. Entsprechend sind der Grundkörper 201 und die Feder 203 jeweils einstückig miteinander verbunden. The tilting segments 105 shown in FIGS. 3 to 6 are exemplary embodiments of the invention. Correspondingly, the base body 201 and the spring 203 are each connected to one another in one piece.
In Fig. 3 hat die Feder 203 die Form einer Tellerfeder, die nach innen hin in den Grundkörper 201 übergeht. Zwischen dem Grundkörper 201 und der Feder 203 be- findet sich eine Aussparung 301. Diese verläuft vollständig um die Längsachse 207 herum und ist in sich geschlossen. Im unteren Bereich weist das Kippsegment 105 eine weitere Aussparung 303 auf. Diese ist bezüglich der Längsachse 207 mittig an- geordnet, sodass die Feder 203 außen am Boden der Vertiefung 205 aufliegt. In Fig. 3, the spring 203 has the shape of a plate spring which merges into the base body 201 towards the inside. There is a recess 301 between the base body 201 and the spring 203. This runs completely around the longitudinal axis 207 and is self-contained. The tilting segment 105 has a further recess 303 in the lower region. This is arranged centrally with respect to the longitudinal axis 207, so that the spring 203 rests on the outside on the bottom of the recess 205.
Fig. 4 zeigt ein Kippsegment 105, bei dem die axialen Wandungen der Vertie- fung 301 parallel zueinander verlaufen. Die Aussparung 301 ist hier spiegelsymmet- risch zu einer radial, das heißt orthogonal zu der Längsachse 207 verlaufenden Ebe- ne. Die Aussparung 303 hat eine zylindrische Form. Eine derartige Ausgestaltung verbessert die Fertigbarkeit. 4 shows a tilting segment 105, in which the axial walls of the recess 301 run parallel to one another. The recess 301 is mirror-symmetrical to a plane running radially, that is to say orthogonally to the longitudinal axis 207. The recess 303 has a cylindrical shape. Such a configuration improves the producibility.
Die Aussparung 303 des in Fig. 5 dargestellten Kippsegments entspricht der in Fig. 3 dargestellten Ausführung. Im Unterschied dazu weist gemäß Fig. 5 die Ausspa- rung 301 parallel zueinander verlaufende Wandungen auf. Auch dies ist im Hinblick auf eine bessere Fertigbarkeit vorteilhaft. Ein weiteres Ausführungsbeispiel des Kippsegments 105 ist in Fig. 6 dargestellt. Hier sind die Aussparungen 301 und 303 so angeordnet, dass sie ineinander übergehen und einen gemeinsamen Hohlraum bilden. Am Grundkörper 201 verläuft die Fe- der 203 hier radial außen in axialer Richtung und verjüngt sich am Fuß der Vertie- fung 205 radial nach innen hin. Die Verjüngung liegt an ihrem inneren Rand auf ei- nem Absatz 601 auf, der vom Boden der Vertiefung 205 gebildet wird. The recess 303 of the tilting segment shown in FIG. 5 corresponds to the embodiment shown in FIG. 3. In contrast to this, according to FIG. 5, the recess 301 has walls running parallel to one another. This is also advantageous in terms of better producibility. Another exemplary embodiment of the tilting segment 105 is shown in FIG. 6. Here, the recesses 301 and 303 are arranged such that they merge into one another and form a common cavity. On the base body 201, the spring 203 here extends radially outward in the axial direction and tapers radially inward at the foot of the recess 205. The taper lies on its inner edge on a shoulder 601 which is formed by the bottom of the depression 205.
