Description
<Desc/Clms Page number 1>
Drehfedernde Kupplung
EMI1.1
<Desc/Clms Page number 2>
lässt sich ein nahezu gleichmässiger Flächendruck erzielen.
In weiterer Ausbildung der Erfindung weisen die in fester Haftverbindung mit dem gummielastischen Material stehenden Metallklötze an ihren jeweils den benachbarten Klötzen zugekehrten Seiten napfförmige Vertiefungen auf. Wie gesagt, soll eine solche Kupplung auch eine gewisse Gelenkigkeit besitzen. Fluchten die beiden zu kuppelnden Wellen nicht genau miteinander, so treten im Gummi auch Schubkräfte auf. Um nun diese Schubkräfte besser übertragen zu können und die Haftverbindung zwischen Metal1kIotz und Gummi zu entlasten, sind die napfförmigen Vertiefungen vorgesehen, die selbstverständlich vom gummielastischen Material ausgefüllt werden.
In den Zeichnungen ist der Erfindungsgegenstand in einem Ausführungsbeispiel dargestellt. Es zeigen Fig. l einen Kupplungsring in Ansicht und Fig. 2 und 3 einen Teil des Ringes im achsnormalen Schnitt und im axialen Schnitt nach der Linie III-111 der Fig. 1 im grösseren Massstab.
In einem ringförmigen Gummikörper--l--sind 16 Metallklötze --3,4-- eingesetzt, die im wesentlichen die Form eines Segmentes besitzen. Von diesen Metal1kIötzen ist nur jeder zweite mit dem Gummi durch Vulkanisation festhaftend verbunden. Diese einvulkanisierten Klötze sind mit--4- bezeichnet, wogegen die Klötze--3--zwar vom Gummi umschlossen sind, der Gummi an ihnen aber nicht haftet. Die Klötze--4--weisen an ihren jeweils den benachbarten Klötzen--3-- zugekehrten Seiten napfförmige Vertiefungen --5-- auf.
Jeder Klotz ist mit einer Bohrung--6-zur Aufnahme eines Verbindungsbolzens versehen, wobei die Klötze--3--mit der einen und die Klötze--4--mit der andern Kupplungshälfte verbunden sind.
Wird beispielsweise das Drehmoment über die Klötze --4-- eingeleitet und soll im Uhrzeigersinn gedreht werden, so wird die Gummizwischenschicht--2-- (Fig. 2) auf Druck

--2'-- keineGummischicht-2'--zusammengedrückt und die Schicht --2-- bleibt zugbelastungsfrei.
PATENTANSPRÜCHE :
1. Drehfedernde Kupplung mit einem ring-oder scheibenförmigen Körper aus Gummi od. dgl. und einer geraden Anzahl von in diesem eingesetzten Metallklötzen, die über achsparallele Bolzen wechselweise mit der treibenden und getriebenen Kupplungshälfte verbunden sind, dadurch ge- kennzeichnet, dass das gummielastische Material nur an jedem zweiten (4) der annähernd segmentförmigen Metallklötze (3,4) fest haftet bzw. anvulkanisiert ist.

an almost even surface pressure can be achieved.
In a further embodiment of the invention, the metal blocks, which are firmly bonded to the rubber-elastic material, have cup-shaped depressions on their respective sides facing the adjacent blocks. As I said, such a coupling should also have a certain flexibility. If the two shafts to be coupled are not exactly aligned with one another, shear forces will also occur in the rubber. In order to be able to transmit these shear forces better and to relieve the adhesive connection between metal block and rubber, the cup-shaped depressions are provided, which are of course filled with rubber-elastic material.
The subject matter of the invention is shown in an exemplary embodiment in the drawings. 1 shows a view of a coupling ring and FIGS. 2 and 3 show part of the ring in a section normal to the axis and in an axial section along line III-111 in FIG. 1 on a larger scale.
In a ring-shaped rubber body - l - 16 metal blocks --3,4 - are inserted, which essentially have the shape of a segment. Of these metal blocks, only every second one is firmly bonded to the rubber by vulcanization. These vulcanized blocks are labeled - 4-, whereas the blocks - 3 - are surrounded by rubber, but the rubber does not adhere to them. The blocks - 4 - have cup-shaped depressions --5 - on their sides facing the neighboring blocks - 3 -.
Each block is provided with a bore - 6 - for receiving a connecting bolt, the blocks - 3 - being connected to one coupling half and the blocks - 4 - to the other.
If, for example, the torque is introduced via the blocks --4-- and is to be turned clockwise, the rubber intermediate layer - 2-- (Fig. 2) is under pressure

--2 '- no rubber layer -2' - compressed and the layer --2-- remains free of tensile loads.
PATENT CLAIMS:
1. Torsion spring coupling with a ring-shaped or disk-shaped body made of rubber or the like and an even number of metal blocks inserted in this, which are alternately connected to the driving and driven coupling halves via axially parallel bolts, characterized in that the rubber-elastic material only adheres or is vulcanized to every second (4) of the approximately segment-shaped metal blocks (3, 4).
