Definitions
- the present invention relates to an eccentric bolt for switch closures according to the preamble of claims 1 and 2.
- the tongue clearance - also called tongue gap or tongue clearance - is set for a switch lock.
- the tongue clearance between the floor rail (also called stock rail) and tongue rail has tolerances of about ⁇ 4 mm, because the floor rail can not be made more accurate as a rolled product.
- the present invention is therefore an object of the invention to provide an eccentric, which can be clamped during assembly so that between eccentric and lock bearing no more play can occur and that impressem can be retrofitted clamped eccentric bolt.
- the inventive eccentric bolt according to claim 2 differs from the eccentric bolt according to claim 1, characterized in that the eccentric pin is inserted into a cylinder-like part - this part is called a cone - and thus causes the cone directly a clamping of locking bearing with the eccentric pin.
- Fig. 1 shows an eccentric bolt 1 for switch locks in a conventional design with two concentrically arranged cylinders 20, 20 'for inclusion in a lock bearing 11, not shown. Between the two cylinders 20, 20' is an eccentrically arranged cylinder 3. For the setting of the Tongue gap is a hexagon socket 21 is provided, can be rotated in the inserted with a Inbuss negotiatel the eccentric 1. By turning the Allen key, the tongue clearance can be adjusted. On the two-edge 18, the fixing disc 5 can be set. With a hex screw 7 (not shown) located in the bore 19, the fixing disc 5 is held in position without being pressed against the lock bearing 11.
- Fig. 2a shows a preferred embodiment of an eccentric bolt 1 for switch locks with two concentrically arranged cylinders 20, 20 'for inclusion in a lock bearing 11.
- the larger cylinder 20 has in its interior a conical shape, in the form-fitting a cone 2 can be inserted.
- the cone 2 (both not shown) is pressed against the cylinder 20 so that it can be clamped against the closure bearing 11.
- the eccentric pin 1 has a thread immediately after the hexagon socket, into which the hexagonal screw 7 engages.
- a plurality of slots 22 are provided on the cylinder 20 in order to effect a better clamping or Aufdgurberry.
- FIGS. 2b and 2c a respective front and rear view of the eccentric pin according to the illustration in FIG. 2a is shown.
- FIG. 3 The cone 2 has - as explained above in relation to the prior art - a hexagon socket 21.
- the cone In order to be able to make an adjustment with an Allen wrench, the cone must have a fixed coupling with the eccentric pin 1 even in the not yet pressed state.
- an oval recess 23 is provided in the eccentric pin 1. This can be seen in detail in FIG. 2b. In this recess 23 engages positively an oval projection 24 of the cone 2 a. It would also be possible to provide the function of oval projection 24 and oval recess 23 reversed in another embodiment.
- the cone 2 By tightening the hex screw 7, the cone 2 is pressed into the larger cylinder 20 of the eccentric pin 1.
- a washer 9 is used for power transmission between the screw head and eccentric 1.
- the conical shape between the cone 2 and the interior of the larger cylinder 20 is selected to be self-locking. Due to the tension of the slotted cylinder 20, the eccentric bolt 1 can now no longer rotate. For this reason, the fixing washer 5 may be pressed against the closure bearing 11.
- the fixing disc 5 may therefore not be pressed because the screw 7 could be solved by a possible rotation of the eccentric pin and thus the fixing disc 5 no longer detects the position of the eccentric pin.
- the fixing washer is no longer a safety-relevant part, but only forms a fallback if the tensioning of the eccentric bolt 1 should fail. This downgrading to a fallback level also applies to the dowel pin 10.
- the tension of the eccentric pin 1 also causes a significant reduction in wear and helps to be able to reduce the maintenance and control costs.
- a screw other than a hexagonal screw 7 may be provided, but for reasons of compatibility with the conventional eccentric pin and for reasons of reducing the variety of parts, the said hexagon screw 7 is preferably retained.
- a sleeve 8 made of elastic material can be provided between the cylinder 3 and the closure pawl 2.
- the preferred material is rubber. Since particularly high accelerations (vibrations) occur when driving on a switch by a train, a stroke limiting ring 14 is additionally installed, so that occurring loads are transmitted symmetrically to the closure pawl 12.
- On the other side of the eccentrically arranged cylinder 3 is a ring 6 - as part of the whole eccentric pin 1, the Fig. 2c only indirectly refer to - provided, whose diameter is equal to the diameter of the Hubbegrenzungsringes 14. This is necessary because the bush 8 made of rubber does not rigidly transmit the occurring stroke or stroke displacement.
- the intermediate layers 16 serve to adjust the Mouth depth at the lock bearing 11 at the distance between the tongue hole - tongue outside edge. They are intended to prevent the closure bearing 11 from rotating about the closure clip screw 15.
- a cylinder-like part - also called a cone - is selected, into which a conically formed cylinder can be inserted by a tensioning or widening of the cone 2 '(not shown in the figures) to effect a firm connection with the closure bearing 11.

Abstract
Description
Die vorliegende Erfindung betrifft einen Exzenterbolzen für Weichenverschlüsse nach dem Oberbegriff der Patentansprüche 1 und 2.The present invention relates to an eccentric bolt for switch closures according to the preamble of
Durch höhere zulässige Geschwindigkeiten von Eisenbahnzügen nimmt die Beanspruchung des Schienenoberbaus und insbesondere jene der Weichen erheblich zu. Mit einem Exzenterbolzen wird für einen Weichenverschluss der Zungenabstand - auch Zungenklaffung oder Zungenspiel genannt - eingestellt. Der Zungenabstand zwischen Stockschiene (auch Backenschiene genannt) und Zungenschiene weist Toleranzen von ca. ± 4 mm auf, weil die Stockschiene als gewalztes Produkt nicht genauer hergestellt werden kann.Due to higher permissible speeds of railway trains, the load on the track superstructure and in particular that of the points significantly increases. With an eccentric bolt, the tongue clearance - also called tongue gap or tongue clearance - is set for a switch lock. The tongue clearance between the floor rail (also called stock rail) and tongue rail has tolerances of about ± 4 mm, because the floor rail can not be made more accurate as a rolled product.
Die z.B. aus der U.S. - Patentschrift 2,148,577 bekannten Exzenterbolzen sind mit einem Schiebesitz im Verschlusslager gelagert. Der Exzenterbolzen konnte sich in seinen Freiheitsgraden, d.h. axial und radial, etwas bewegen. Ebenso musste ein Spiel zwischen Exzenterbolzen und einer Fixierscheibe vorgesehen werden, da die Fixierscheibe von der Sicherungsschraube nicht an das Verschlusslager angepresst werden darf, weil sonst bei einer Drehung des Exzenterbolzens innerhalb seines Spiels die Gefahr bestanden hätte, dass die Sicherungsschraube aufgedreht wird. Mit einer Zweikantkopplung kann die Fixierscheibe auf nur eine Art an den Exzenterbolzen gekoppelt werden. Mit verschiedenen radial angeordneten Löchern kann eine bestimmte Position der Fixierscheibe und damit des Exzenterbolzens eingestellt werden. Auf diese Weise wird der Abstand der Zungenklaffung vor Ort eingestellt und fixiert. Eines der vorgenannten Löcher greift dabei in einen am Verschlusslager eingepressten Passkerbstift ein.The e.g. from U.S. Pat. Patent 2,148,577 known eccentric bolts are mounted with a sliding seat in the lock stock. The eccentric bolt was able to move in its degrees of freedom, i. axial and radial, move something. Likewise, a game between eccentric bolt and a fixing washer had to be provided because the fixing washer must not be pressed by the locking screw to the lock bearing, otherwise there would have been a danger during rotation of the eccentric bolt within his game that the locking screw is turned on. With a two-way coupling, the fixing disc can be coupled to the eccentric pin in only one way. With different radially arranged holes, a specific position of the fixing disc and thus of the eccentric pin can be adjusted. In this way, the distance of the tongue gap is adjusted and fixed on site. One of the aforementioned holes engages in a pressed-in on the lock stock passog.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, einen Exzenterbolzen anzugeben, der bei der Montage so verspannt werden kann, dass zwischen Exzenterbolzen und Verschlusslager kein Spiel mehr auftreten kann und dass beeinem verspannbaren Exzenterbolzen nachgerüstet werden können.The present invention is therefore an object of the invention to provide an eccentric, which can be clamped during assembly so that between eccentric and lock bearing no more play can occur and that impressem can be retrofitted clamped eccentric bolt.
Diese Aufgabe wird durch die im Patentanspruch 1 oder 2 angegebenen Massnahmen gelöst.This object is achieved by the measures specified in
Dadurch, dass gemäss Anspruch 1
in den einen koaxial angeordneten Zylinder ein Konus einschiebbar ist und ein Befestigungsmittel vorgesehen ist, mit dem durch den Konus der genannte Zylinder aufdrückbar ist, um mit dem Verschlusslager eine Verspannung zu erwirken;
ist der Exzenterbolzen fest mit dem Verschlusslager verbunden und kann weder in radialer noch axialer Richtung verschoben werden.Due to the fact that according to
in which a coaxially arranged cylinder, a cone is inserted and a fastening means is provided, with which by the cone of said cylinder is aufdrückbar to obtain a tension with the closure bearing;
the eccentric bolt is firmly connected to the lock bearing and can not be moved in the radial or axial direction.
Der erfindungsgemässe Exzenterbolzen gemäss Anspruch 2 unterscheidet sich vom Exzenterbolzen gemäss Anspruch 1 dadurch, dass der Exzenterbolzen in ein zylinderartiges Teil einschiebbar ist - dieses Teil wird Konus genannt - und dadurch der Konus direkt eine Verspannung von Verschlusslager mit dem Exzenterbolzen bewirkt.The inventive eccentric bolt according to
Vorteilhafte Ausgestaltungen der Erfindung sind in weiteren Ansprüchen angegeben.Advantageous embodiments of the invention are specified in further claims.
So können sich die folgenden Vorteile zusätzlich ergeben:
- i) Dadurch, dass
der eine koaxial angeordneten Zylinder oder der Konus Schlitze aufweist;
ergibt sich eine Aufweitung mit einem geringeren Kraftaufwand und damit eine verbesserte Verspannung von Exzenterbolzen oder Konus mit dem Verschlusslager. (Patentanspruch 3 oder 4). - ii) Dadurch, dass
der eine koaxiale Zylinder mit dem Konus formschlüssig so verbunden ist, dass die Verbindung nach erfolgter Befestigung mit dem Befestigungsmittel selbsthemmend Befestigung mit dem Befestigungsmittel selbsthemmend ist;
wird eine Verspannung sichergestellt, auch wenn das Befestigungsmittel aus äusseren Umständen ausgefallen sein sollte, ohne dass direkt eine sicherheitsrelevante Rückfallebene zwingend vorgesehen werden muss (Patentanspruch 6). - iii) Dadurch, dass
der exzentrisch angeordnete Zylinder über eine aus einem elastischen Material hergestellte Büchse mit der Verschlussklinke drehbar gekoppelt ist;
werden auftretende Vibrationen zwischen Verschlussklinke und Verschlusslager gedämpft (Patentanspruch 9). - iv) Dadurch, dass
der exzentrisch angeordnete Zylinder auf der einen Seite einen Ring aufweist, dessen Durchmesser grösser ist als jener des exzentrisch angeordneten Zylinder und dass auf der anderen Seite ein Hubbegrenzungsring einschiebbar ist, dessen Durchmesser gleich dem Durchmesser des Rings ist und dass die Büchse zwischen Ring und Hubbegrenzungsring angeordnet ist;
werden die auftretenden Belastungen zwischen Verschlussklinke und Verschlusslager symmetrisch übertragen (Patentanspruch 11).
- i) Because of that
having a coaxially arranged cylinder or the cone slots;
results in an expansion with a lower force and thus improved clamping of eccentric or cone with the lock stock. (Claim 3 or 4). - ii) By:
a coaxial cylinder with the cone is positively connected so that the connection after attachment with the fastener self-locking Attachment with the fastener is self-locking;
a bracing is ensured, even if the fastener should be out of external circumstances, without directly a safety-relevant fallback level must be provided mandatory (claim 6). - iii) the fact that
the eccentric cylinder is rotatably coupled to the pawl via a bush made of an elastic material;
occurring vibrations between the lock pawl and lock bearing are damped (claim 9). - iv) the fact that
the eccentrically arranged cylinder on one side has a ring whose diameter is greater than that of the eccentrically arranged cylinder and that on the other side a Hubbegrenzungsring is inserted, whose diameter is equal to the diameter of the ring and that the sleeve between the ring and Hubbegrenzungsring arranged is;
the loads occurring between the locking latch and locking bearing are transmitted symmetrically (claim 11).

Fig. 1 zeigt einen Exzenterbolzen 1 für Weichenverschlüsse in herkömmlicher Bauart mit zwei konzentrisch angeordneten Zylindern 20, 20' zur Aufnahme in einem nicht dargestellten Verschlusslager 11. Zwischen den beiden Zylindern 20, 20' befindet sich ein exzentrisch angeordneter Zylinder 3. Für die Einstellung des Zungenabstandes ist ein Innensechskant 21 vorgesehen, in den mit einem eingesetzten Inbussschlüssel der Exzenterbolzen 1 gedreht werden kann. Durch Drehen des Inbusschlüssels lässt sich somit der Zungenabstand einstellen. Auf den Zweikant 18 kann die Fixierscheibe 5 gesetzt werden. Mit einer in der Bohrung 19 befindlichen Sechskantschraube 7 (nicht dargestellt) wird die Fixierscheibe 5 in ihrer Position gehalten, ohne dass sie an das Verschlusslager 11 angepresst wird.Fig. 1 shows an
Fig. 2a eine bevorzugte Ausführungsform eines Exzenterbolzens 1 für Weichenverschlüsse mit zwei konzentrisch angeordneten Zylindern 20, 20' zur Aufnahme in einem Verschlusslager 11. Um einen bestehenden Weichenverschluss mit einem Exzenterbolzen 1 der erfindungsgemässen Gattung nachrüsten zu können, sind die Abmessungen gegenüber Verschlusslager 11 und Verschlussklinke 12 weitgehend identisch. Der grössere Zylinder 20 weist in seinem Inneren eine konische Form auf, in die formschlüssig ein Konus 2 einschiebbar ist. Mit einer Sechskantschraube 7 wird der Konus 2 (beide nicht dargestellt) gegen den Zylinder 20 gedrückt, so dass dieser gegenüber dem Verschlusslager 11 verspannt werden kann. Dazu weist der Exzenterbolzen 1 unmittelbar nach dem Innensechskant ein Gewinde auf, in das die Sechskantschraube 7 eingreift. Vorzugsweise sind am Zylinder 20 mehrere Schlitze 22 vorgesehen, um eine bessere Verspannung bzw. Aufdrückbarkeit zu bewirken.Fig. 2a shows a preferred embodiment of an
In den Fig. 2b und 2c ist je eine Vorder- und Hinter-Ansicht des Exzenterbolzens gemäss der Darstellung in Fig. 2a gezeigt.In FIGS. 2b and 2c, a respective front and rear view of the eccentric pin according to the illustration in FIG. 2a is shown.
Für die Erläuterung der weiteren Teile wird zunächst Bezug auf die Fig. 3 genommen. Der Konus 2 weist - wie auch vorstehend zum Stand der Technik erläutert - einen Innensechskant 21 auf. Um mit einem Inbusschlüssel eine Einstellung vornehmen zu können, muss auch im noch nicht angepressten Zustand der Konus eine feste Kopplung mit dem Exzenterbolzen 1 aufweisen. Dazu ist eine ovale Ausnehmung 23 im Exzenterbolzen 1 vorgesehen. Im Detail ist dies der Fig. 2b zu entnehmen. In diese Ausnehmung 23 greift formschlüssig ein ovaler Vorsprung 24 des Konus 2 ein. Es wäre auch möglich, in einer anderen Ausführungsform die Funktion von ovalem Vorsprung 24 und ovaler Ausnehmung 23 vertauscht vorzusehen.For the explanation of the other parts, reference is initially made to FIG. 3. The
Aus der Fig. 2c ist die Lage des exzentrisch angeordneten Zylinders 3 ersichtlich. Damit der Exzenterbolzen 1 von rechts her (siehe dazu Fig. 3) bei der Montage in das Verschlusslager 11 und die Verschlussklinke 12 eingeschoben werden kann, darf der exzentrisch angeordneten Zylinder 3 die Umhüllung des grösseren Zylinders 20 nicht überschreiten.From Fig. 2c, the position of the eccentrically arranged
Durch Anziehen der Sechskantschraube 7 wird der Konus 2 in den grösseren Zylinder 20 des Exzenterbolzens 1 gepresst. Zur Kraftübertragung zwischen Schraubenkopf und Exzenterbolzen 1 dient eine Unterlagscheibe 9. Die konische Form zwischen Konus 2 und dem Innern des grösseren Zylinders 20 ist selbsthemmend gewählt. Durch die Verspannung des geschlitzten Zylinders 20 kann sich nun der Exzenterbolzen 1 nicht mehr drehen. Aus diesem Grunde darf die Fixierscheibe 5 an das Verschlusslager 11 angepresst werden. Unter Verwendung eines herkömmlichen Exzenterbolzens 1' darf die Fixierscheibe 5 deshalb nicht angepresst werden, weil durch eine mögliche Drehung des Exzenterbolzens die Schraube 7 gelöst werden könnte und dadurch die Fixierscheibe 5 nicht mehr die Lage des Exzenterbolzens feststellt. Gemäss der vorliegenden Erfindung ist die Fixierscheibe kein sicherheitsrelevantes Teil mehr, sondern bildet nur noch eine Rückfallebene, falls die Verspannung des Exzenterbolzens 1 versagen sollte. Diese Rückstufung auf eine Rückfallebene gilt auch für den Passkerbstift 10. Die Verspannung des Exzenterbolzens 1 bewirkt auch eine deutliche Reduktion des Verschleisses und hilft, den Wartungs- und Kontrollaufwand reduzieren zu können.By tightening the hex screw 7, the
Zum Einpressen des Konus 2 kann auch eine andere Schraube als eine Sechskantschraube 7 vorgesehen sein, aus Gründen der Kompatibilität zum konventionellen Exzenterbolzen und aus Gründen der Reduktion der Teilevielfalt wird jedoch vorzugsweise die genannte Sechskantschraube 7 beibehalten.For pressing in the
Um eine gute Dämpfung zu erlangen, wird kann zwischen dem Zylinder 3 und der Verschlussklinke 2 eine Büchse 8 aus elastischem Material vorgesehen sein. Als Material wird vorzugsweise Gummi gewählt. Da beim Befahren einer Weiche durch einen Zug besonders hohe Beschleunigungen (Vibrationen) auftreten wird zusätzlich ein Hubbegrenzungsring 14 eingebaut, damit auftretende Belastungen symmetrisch auf die Verschlussklinke 12 übertragen werden. Auf der anderen Seite des exzentrisch angeordneten Zylinders 3 ist ein Ring 6 - als Teil des ganzen Exzenterbolzens 1 , der Fig. 2c nur indirekt zu entnehmen - vorgesehen, dessen Durchmesser gleich dem Durchmesser des Hubbegrenzungsringes 14 ist. Dies ist erforderlich, weil die Büchse 8 aus Gummi den auftretenden Hub bzw. Hubverschiebung nicht starr überträgt.In order to obtain a good damping, a sleeve 8 made of elastic material can be provided between the
Als weitere Rückfallebene dient die Schraubensicherung 17, die über das Verschlusslager 11 einschliesslich der Fixierscheibe 5 gestülpt wird und die Verschlussklammerschraube 15 sichert. Die Zwischenlagen 16 dienen der Einstellung der Maultiefe beim Verschlusslager 11 an die Distanz Zungenbohrung - Zungenaussenkante. Mit ihnen soll verhindert werden, dass sich das Verschlusslager 11 um die Verschlussklammerschraube 15 dreht.As a further fallback the
Die vorliegende Erfindung ist nicht auf die vorstehend erläuterte Ausführungsform beschränkt. Es könnte auch vorgesehen sein, dass das anstelle des einen Zylinders 20 ein zylinderartiges Teil - ebenfalls Konus genannt - gewählt wird, in das ein konisch ausgebildeter Zylinder einschiebbar ist um eine Verspannung bzw. Aufweitung des Konus 2' (in den Figuren nicht dargestellt) zu erwirken um damit eine feste Verbindung mit dem Verschlusslager 11 zu bewirken. Vorzugsweise weist die besseren Aufweitbarkeit oder Aufdrückbarkeit dieser Konus 2' ebenfalls Schlitze auf.The present invention is not limited to the above-described embodiment.
