Abstract

The invention relates to a transport lock (1) for lockable retaining or snap rings (4, 5) punched from sheet metal and provided with a radial slot (2, 3), wherein opposite end faces (8, 9) of the outer surfaces (6, 7) of two unlocked rings (4, 5) adjoin each other flush with each other at the level of the radial slots (2, 3) in such a way that between said radial slots a continuous open passage (10) is formed. To provide the transport lock (1), portions (11, 12) of the outer surfaces (6, 7) of the two rings (4, 5) situated on the same side of said rings are connected to each other using material (13) with a preset breaking point.

Description

Transportsicherung  transport safety
Die Erfindung betrifft eine Transportsicherung für aus Blech gestanzte, spannbare sowie mit einem Radialschlitz versehene Sicherungs- oder Sprengringe. The invention relates to a transport lock for punched from sheet metal, tensionable and provided with a radial slot backup or snap rings.
Sicherungsringe, auch Halteringe genannt, sowie Sprengringe gehören zur Gruppe der axialen Sicherungselemente und werden u. a. zur Lagefixierung bei Wellen oder Achsen eingesetzt. Sie können als Normteile vorliegen, so wie bspw. in den DIN 471 , 472 o. 5417 beschrieben. Circlips, also called retaining rings, as well as snap rings belong to the group of axial securing elements and are u. a. used for positional fixation on shafts or axles. They can be present as standard parts, as described, for example, in DIN 471, 472 or 5417.
Die vorbeschriebenen Ringe werden im Stand der Technik auch bei schaltba- ren Rollenstößeln oder Abstützelementen in Ventiltrieben von Brennkraftmaschinen appliziert; hier als Höhenanschlag und als Mittel zur Einstellung eines Koppelspiels (s. DE 102 04 672 A1 , DE 10 2007 01 1 892 A1 ). The above-described rings are also applied in the prior art with switchable roller tappets or supporting elements in valve drives of internal combustion engines; here as a height stop and as a means for setting a coupling play (see DE 102 04 672 A1, DE 10 2007 01 1 892 A1).
Bei einem Transport der Ringe als Schüttgut verhaken sich diese in ihren Be- hältern kettengliedartig. Somit müssen die Ringe vor deren Verbau aufwändig einzeln per Hand separiert und können nicht ohne Weiteres automatisiert gegriffen werden. Dies wirkt sich letztlich nachteilig auf die Fertigungskosten aus. Im Worst Case besteht zudem die Gefahr, geringfügig verbogene Ringe zu montierten. When the rings are transported as bulk material, they get caught in their containers like a chain link. Thus, the rings must elaborately separated individually by hand before their installation and can not be automatically gripped easily. This ultimately adversely affects the manufacturing costs. In the worst case, there is also the danger of mounting slightly bent rings.
Es ist Aufgabe der Erfindung, als Schüttgut transportierbare Sicherungs- oder Sprengringe vorzuschlagen, die sich leicht endmontieren lassen. It is an object of the invention to propose as bulk transportable safety or snap rings, which can be easily finalmontieren.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass zwei ungespannte Ringe mit ihren Außenmänteln bei deren aufeinander zu weisenden Endstirnen an den Radialschlitzen derartig fluchtend aneinander grenzen, dass zwischen Letztgenannten ein durchgehend offener Kanal gebildet ist, wobei zur Darstel- lung der Transportsicherung jeweils gleichseitige Abschnitte der Außenmäntel der beiden Ringe über Sollbruchmaterial aneinander gebunden sind. According to the invention, this object is achieved in that two unstressed rings with their outer sheaths adjoin one another in such a way that they are in alignment with one another at the radial slots so that a continuously open channel is formed between the latter. tion of the transport lock each equilateral sections of the outer shells of the two rings are bonded to each other via predetermined breaking material.
Somit sind die eingangs genannten Nachteile eliminiert. Durch die paarweise über Sollbruchmaterial verbundenen Ringe, wobei auch aneinander hängende Paargruppen vorgesehen sind, können sich die Ringe während eines Transports als Schüttgut nicht mehr verhaken. Somit entfällt vor deren Verbau das aufwändige Auflösen der unerwünscht gebildeten Ringketten. Die Fertigungskosten sind letztlich gesenkt. Gleichzeitig liegen die Ringe in vergleichsweise stabiler Anordnung vor und können paarweise an ihren Stirnen einer Feinbearbeitung durch Schleifen unterzogen werden. Thus, the disadvantages mentioned above are eliminated. Due to the pairs connected via predetermined breaking material rings, which are also provided to each other hanging pair groups, the rings can not get caught during transport as bulk material. Thus eliminates the costly dissolution of the unwanted ring chains before their installation. The manufacturing costs are ultimately lowered. At the same time, the rings are in a comparatively stable arrangement and can be subjected in pairs to their foreheads of a fine machining by grinding.
Gemäß einer besonders bevorzugten Fortbildung der Erfindung sind zur Darstellung des Sollbruchmaterials einteilig angebundene Stege vorgeschlagen, welche beim Stanzen des entsprechenden Ringpaares entsprechend mit ausgebildet werden. Diese Stege liegen unmittelbar bei den aneinander grenzenden Abschnitten der Ringe, d. h. entweder auf der Seite der Endstirnen oder „hinter" den Anlagebereichen, in Umfangsrichtung von den Endstirnen entfernt. Auch können die Stege auch aus separatem Material wie Kunststoff oder ei- nem wachsähnlichen Werkstoff bestehen, welcher optional bei Erwärmung in einen Flüssigzustand übergeht und die Ringverbindung somit freigibt. According to a particularly preferred embodiment of the invention, integrally connected webs are proposed for the representation of the predetermined breaking material, which are formed accordingly during punching of the corresponding ring pair. These webs are located directly at the adjacent sections of the rings, d. H. either on the side of the end stems or "behind" the abutment areas, circumferentially away from the end stems, and the webs can also be made of separate material, such as plastic or a wax-like material, which optionally undergoes heating to a liquid state and thus the ring connection releases.
Alternativ ist es vorgesehen, die Ringe über eine Material brücke direkt zwischen ihren aneinander grenzenden Abschnitten deren Außenmäntel zu kop- peln und diesen Brückenabschnitt als Bruchbereich vorzusehen. Somit liegen de facto keine separaten Stege vor. Alternatively, it is provided to couple the rings via a material bridge directly between their adjoining sections whose outer shells and to provide this bridge section as a break region. Thus de facto no separate webs are available.
Bei beiden vorgenannten Lösungen ist es vorteilhaft, das jeweilige Brückenglied (Steg, Materialbrücke) dünnwandiger als das restliche Ringmaterial dar- zustellen und ggf. zu kerben. Somit wird ein Trennen des Ringpaares unmittelbar vor einer Endmontage erleichtert. Die Ringe können neben deren Stahlblechausbildung (bspw. Vergütungsstahl, Lieferbezeichnung CK 75) auch aus Kunststoff oder einem Verbundwerkstoff bestehen. In both of the abovementioned solutions, it is advantageous to present the respective bridge member (web, material bridge) with a thinner wall than the remainder of the ring material and possibly score it. Thus, a separation of the ring pair is facilitated immediately before a final assembly. The rings can be made of plastic or a composite material in addition to the steel sheet training (eg tempered steel, delivery name CK 75).
Ein Ausführungsbeispiel der Erfindung geht aus der Zeichnung hervor. An embodiment of the invention will become apparent from the drawing.
• Es zeigt die einzige Figur ein Paar von Sicherungsringen mit Transportsicherung. • The only figure shows a pair of circlips with transport lock.
Dargestellt ist ein Paar von aus Blech gestanzten Sicherungsringen 4, 5. Jeder Ring 4, 5 hat einen Radialschlitz 2, 3. Zu erkennen ist, dass die Ringe 4, 5, ein- oder auswärts nicht gespannt, mit ihren Außenmänteln 6, 7 unmittelbar mit Ih- ren Radialschlitzen 2, 3 aneinander grenzen. Jeder Ring 4, 5 läuft vor seinem Radialschlitz 2, 3 mit aufeinander zu weisenden Endstirnen 8, 9 in einem augenartigen Bereich aus. Zwischen den Radialschlitzen 2, 3 ist ein durchgehend offener, materialfreier Kanal 10 gebildet. Die beiden Ringe 4, 5 sind über eine Transportsicherung 1 miteinander verbunden. Zur Darstellung dieser sind jeweils gleichseitige Abschnitte 1 1 , 12 der Außenmäntel 6, 7 der beiden Ringe 4, 5 über Sollbruchmaterial 13 aneinander gebunden. Als Sollbruchmaterial 13 sind der links gezeichnete Abschnitt 1 1 über einen dünnwandigen Steg 14 und der rechts dargestellte Abschnitt 12 über einen dünnwandigen Steg 15 gekoppelt. Die Stege 14, 15 sind hierbei einteilig angebunden und gehen von den Endstirnen 8, 9 aus. Shown is a pair of stamped from sheet metal circlips 4, 5. Each ring 4, 5 has a radial slot 2, 3. It can be seen that the rings 4, 5, on or off not stretched, with their outer shells 6, 7 directly with their radial slots 2, 3 adjoin one another. Each ring 4, 5 runs in front of its radial slot 2, 3 with mutually facing Endstirnen 8, 9 in an eye-like area. Between the radial slots 2, 3 a continuous open, material-free channel 10 is formed. The two rings 4, 5 are connected to each other via a transport lock 1. To illustrate this are each equilateral sections 1 1, 12 of the outer shells 6, 7 of the two rings 4, 5 bonded via predetermined breaking material 13 to each other. As a predetermined breaking material 13 of the left-hand section 1 1 are coupled via a thin-walled web 14 and the section 12 shown on the right via a thin-walled web 15. The webs 14, 15 are in this case connected in one piece and start from the Endstirnen 8, 9.
