However, the elastic buffers of an inner group or the inner group need not necessarily be harder than the elastic buffers of an outer group or the outer group; they may also be substantially equally hard or softer than the latter.
In a further preferred embodiment, the annular intermediate part arranged between two adjacent groups of elastic buffers comprises radially inwardly projecting elevations and radially outwardly projecting elevations, the respective inwardly and outwardly projecting elevations defining buffer contact surfaces or positive-fit surfaces.
This embodiment is advantageous in relation to changing a group of buffers for harder or tschan coupling buffers without the buffers of the tschan coupling group s having to be changed in this case.
The annular intermediate part of the coupling according to the invention may also be referred to as a star-shaped intermediate part. The annular intermediate part is preferably made of plastics material or light metal, for example of aluminium or an aluminium alloy.

As a result, the weight of the coupling according to the invention can be reduced or at least limited to a predetermined total weight. Further, the annular intermediate part can be produced more simply in this case, since a plastics material or light metal workpiece starting workpiece can more easily be machined tschan coupling cutting than tschan coupling example a steel workpiece.
However, the at least one annular intermediate part of the coupling according to the invention may also be made of a metal other than light metal, in particular of steel.
A further advantageous embodiment of the coupling according to the invention provides that the annular intermediate part is assembled from at tschan coupling two axially separable parts. This embodiment facilitates the mounting of the elastic buffers. The at least two axially separable parts are optionally provided with connecting means, in such a way that they can be releasably interconnected.
The releasable connection means may for example be configured as a screw connection or releasable latch connection. Alternatively, the annular intermediate part may also be configured in a single piece. The elastic buffers and tschan coupling annular intermediate piece are preferably separately produced components which are interconnected with a positive fit rather than being integrally bonded in the coupling according to the invention.

However, in an alternative embodiment of the coupling according to the invention, the annular intermediate part may also be integral with one or both of the adjacent groups of elastic buffers. This embodiment is advantageous regarding rapid and complete mounting of the elastic buffers. Further, with regard to as uniform an oscillation damping as possible for a compact tschan coupling of the coupling, it is favourable if according to a further preferred embodiment of the invention the groups or at least two of the groups comprise the same amount of elastic buffers.
A further advantageous embodiment of the coupling according to the invention is characterised in that the elastic buffers of one of the groups are arranged offset tschan coupling the circumferential direction relative to the elastic buffers of the adjacent, radially spaced group.
This embodiment makes possible a particularly compact construction of the coupling according to the invention. Another further embodiment of the coupling according to the invention involves it being provided with a mass damper.
The mass damper is preferably formed tschan coupling such a way that the spring constant or torsional spring constant thereof can be adjusted to a frequency to be damped or cancelled out.
Preferably, the mass damper comprises rubber-resilient elements as springs and an annular body as a mass, the rubber-resilient elements being arranged in clearances formed both in the outer surface of the outer part and in the inner surface of the annular body.
This embodiment of the mass damper is convenient to implement in terms of production, and makes possible simple adjustment of the mass damper in relation to a frequency to be damped or cancelled out.
In the following, the invention is explained in greater detail by way of drawings which show a plurality of embodiments and in which, schematically: The elastic coupling tschan coupling in FIGS. It is constructed from a metallic outer part 1, a metallic inner part 2, a plurality of elastic buffers 3, 4 tschan coupling an annular intermediate part 5.
The outer part 1 is provided with a flange 6 which comprises a plurality of holes 7 to fix screws. The inner part 2 comprises a hub 8, which comprises for example a groove 9 for receiving an inlay key connected to a shaft to be driven.
However, the connection of the outer part 1 and the inner part 2 to the shafts to be coupled may also be configured in another way, in particular also using a frictional connection. The elastic buffers 3, 4 are arranged in two groups rows which are spaced apart radially.

The annular intermediate part tschan coupling, which is made of plastics material or metal, preferably from light metal, is arranged between the buffer groups.
The annular intermediate part 5 is star-shaped cf.
The outer part 1 comprises radially inwardly projecting elevations 1.
