- the assembly can be considerably simplified.
- Known solutions often require that the shaft sections to be connected and the units connected thereto for mounting the coupling device must be brought into a mounting position that does not correspond to their operating position. This is necessary because conventional couplings usually can not be mounted in a state of stress. In the present invention, however, due to the use of the two other coupling parts connecting elastic and optionally flexible connection arrangement does not come to such a requirement.

It is possible that the Buchstrangabites each have at least one tension spring element, preferably at least one thread-reinforced rubber strap having. Preferably, it can be provided that the tension cord section has a plurality of mechanically arranged in series and / or parallel rubber straps.
- a further development of the invention provides at least one intermediate coupling part, which is arranged between the first and the second coupling part and has a central axis of rotation, wherein the connecting links on mutually facing areas on the at least one extending in the radial direction
- the intermediate coupling part it is possible for this to be arranged radially inside or radially outside the connecting links.
- the intermediate coupling part can thus be arranged, for example, as a central body in the center of the coupling device according to the invention between the two coupling parts.
- the elastic connection arrangement of at least one pair of connecting links and the tension cord section coupled thereto can therefore point radially inward or radially outward.
- the at least one tensile strand section is arranged in an articulated manner on the intermediate coupling part. This also makes it possible to avoid that the tension cord section is undesirably subject to bending or deflection stresses during operation.
- the articulated attachment in particular shows advantages when compensating axial misalignment situations.
- the intermediate coupling part is freely movable relative to the first and second coupling parts.
- the intermediate coupling part can thus move as neutral a position as possible and compensate for the angular, radial or axial axial offset by taking such a neutral position. It is as it were about the respective connection arrangements with
- a further embodiment variant of the invention provides that at least one of the first and second coupling part comprises a first coupling body with a plurality of coupling arms extending radially from a central portion and a second coupling body having a plurality of coupling arms extending radially from a central portion.
- the coupling body may be provided, for example, star-shaped with two, three, four, five or more coupling arms. The coupling arms can directly attack each other in case of overload or in case of failure and thus form a spin-on protection.
- a development of the invention provides that the first coupling part and the second coupling part are arranged at rest in such angular offset from one another that the coupling arms of the first coupling part and the coupling arms of the second coupling part are arranged alternately successively at regular angular intervals.
- the two coupling parts for example, engage each other like a tooth.
- the first or / and the second coupling part has a connection section for a shaft section, from which the coupling projections extend on a frustoconical surface.
- this arrangement allows the insectskup ⁇ plunging part can be arranged within the free space of the truncated cone described by the coupling projections.
- the coupling device according to the invention can be made compact not only in the axial direction but also in the radial direction.
- the adjacent coupling projections of a coupling part are rigidly connected to one another by transverse struts.

- Fig. 7 is a front view of a third embodiment of the invention.
- FIG. 8 shows an axis-containing sectional view along the section line VIII-VIII of FIG.
- Fig. 9 is a front view of a fourth embodiment of the invention.
- FIG. 10 shows an axis-containing sectional view of the device according to the invention from FIG. 9 along the section line X-X;
- Fig. 11 is a front view of a fifth embodiment of the invention.
- Fig. 12 is an axis-containing sectional view of the coupling device according to
- a coupling device according to the invention is shown in a spatial representation and generally designated 10.
- This comprises a first coupling part 12 for coupling with a first shaft portion, which is formed over a pot portion 14.
- the coupling device 10 further includes a second coupling part 16, which is formed substantially identical to the first coupling part 12 and has a pot portion 18 as it were. It can be seen that in the pot portion, a star-shaped inner profile 20 and 22 is provided, into which a correspondingly profiled shaft portion without play or with play for torque transmission in its axial direction A can be used.
- each coupling part 12 and 16 have arm-like coupling projections 24 and 26, respectively. More specifically, each coupling part has six arm-like coupling projections, which are generally indicated at 24i to 24 6 in FIG. Correspondingly many coupling projections 26 are provided in the coupling part 12. It can further be seen that the individual coupling projections, starting from the pot 18, where they have a section 28 extending essentially in the axial direction, extend in a transition section 30 essentially along a truncated cone surface. Starting from the transition section 30, the coupling projections 24 are angled and form a radial section 32.
- All coupling projections 24i to 24 ⁇ lie, so to speak, in a common plane substantially orthogonal to the plane.
- the radial sections 32i to 32 6 with the corresponding radial sections 38 of the other coupling part 12 are in an initial state in a substantially common axis orthogonal plane, as can be seen in FIGS. 1 and 4. In the operating state, however, this is to be expected at best in rare cases.
- the clutch 10 is, as will be described in more detail below, just designed to compensate for strong axial misalignment situations in which two shaft sections connected to the coupling parts 12 and 16 have strong parallel offset, axial offset, radia ⁇ len offset or angular offset, or even strongly skewed to each other are arranged.
- connection arrangements ver ⁇ 42nd More precisely, six connection arrangements are again provided, as shown in FIG. 2 and designated there by 42 i to 42 6 .
- the connection arrangements gene 42 have two mutually angled connecting members 44, 46. These are each articulated via connecting bolts 48 to a coupling projection 24 and 26, respectively.
- FIGS. 2 and 4 it can be seen that actually two connection elements 44 and 46 arranged in parallel are provided per connection arrangement 42.
- the connecting links are connected via a solidly formed coupling element 50.
- hinge pins 52 are used. The hinge pins 48 and 52 pass through the links and are mounted in openings of the radial portions 32 and 38 of the coupling projections 24 and 26, respectively.
- a similar connection is located on the coupling elements 50.
- chains of connecting straps indicated generally at 54, extend.
- These chains 54 of connecting straps in the embodiment shown each comprise four connecting straps. A total of four such chains 54 are arranged, two side by side and two behind each other, as shown in Fig. 1 can be seen.
- These chains of connecting straps form radially extending tension cord sections, which are pivotally mounted at one end to the coupling element 50 and at its other end also hinged to a disc-shaped intermediate coupling part 60th
- connection arrangement 42 thus comprises two pairs of connecting members 44 and 46, a coupling element 50 and a radial Wernergate of corresponding link chains 54 which form a Y configuration and thus adjacent coupling arms 24 and 26 of the two coupling parts 12 and 18 with the involvement of the intermediate coupling part 60th connect with each other.
- the illustrated Y configuration of each connection assembly has advantages that will be described below.
- connection arrangements are used for assembly. These are designed as rubber straps with eyelets, wherein in the rubber material the eyelets are wrapped around looping thread inserts. It is well known that such pull tabs have a very long service life very good tensile transfer properties and also in difficult environments with thermal stress exposure to aggressive media inventory. Such tabs are used for example in this or similar form in various industrial applications but also in the motor vehicle and commercial vehicle sector.
- the two coupling parts 12 and 16 are each mounted on their inner profiles 20 and 22 at corresponding shaft portions (not shown), which are for example formed at the end with a square profile, which are receivable with a certain play in the inner profiles 20, 22. In this case, the two coupling parts can be positioned to each other such that the connection arrangements are de-energized. If necessary. If necessary, the connection arrangements can also be detached from the coupling parts 12, 16 on one or two sides.
- the arrangement according to the invention shows particular advantages, because their elastic ⁇ cal damping behavior solely on relative movements of the two pairs of connecting members 44, 46 and pure tensile stress of the Switzerlandstrangabitese 54 takes place , The forces acting on the individual components can thereby be significantly reduced compared to conventional arrangements.
- a significant advantage lies in the possibility of compensating for substitute situations. Overall, a long service life can be achieved with this coupling device, although the individual components do not have to be made excessively massive.
- the clutch as a whole can be made smaller or even adapted only by designing the tension cord sections to be correspondingly weaker, for example by using a small number of pull tab chains.
- This has the advantage that the total coupling can be composed of standard components and, depending on the application (load situation), a correspondingly appropriate design of the tensile-strand sections taking into account the required mechanical safety.
- FIGS. 1 to 4 show a modification of the embodiment according to the invention, wherein in the following only the differences from the first embodiment according to FIGS. 1 to 4 will be discussed. To avoid repetition and to simplify the description, the same reference numerals are used for the same components as above.
- the embodiment according to FIGS. 5 and 6 differs from the embodiment according to FIGS. 1 to 4 only in that the rigid connecting struts 44 and 46 from FIGS. 1 to 4 are replaced by chain sections 70 and 72, respectively.
- the chain sections themselves are formed of steel links and substantially rigid in themselves, ie they have little elasticity of their own against the elasticity of the radially extending tensile strand sections 54. However, their flexibility as a chain distinguishes them from the embodiment according to FIGS. 1 to 4, which offers advantages in assembly and disassembly.
- the chain portions 70, 72 formed sufficiently strong strong load to withstand the forces occurring in the case of torque transmission.
- the embodiment according to FIGS. 7 and 8 is similar to the embodiment according to FIGS. 5 and 6.
- chain sections 70, 72 made of steel links replaced by also in the pulling direction elastically formed chains of rubber straps, as they are also used for the Switzerlandstrangabroughe 54.
- These chains are designated by the reference numeral 76, 78. As can be seen in Fig. 8, these chains 76, 78 are arranged in pairs.
- FIG. 7 Another difference with previous embodiments is the design of the coupling element.
- the coupling element formed rectangular in the front view in FIG. 5
- a substantially triangular coupling element 80 is shown in FIG. 7, which comprises the chain sections 76 and 78 as well as the
- FIGS. 9 and 10 is in turn similar to the embodiment according to FIGS. 5 and 6, wherein chain sections 82, 84 which can be mounted there are used in a more massive embodiment than is the case in the embodiment according to FIGS. 5 and 6.
- FIGS. 11 and 12 an arrangement similar to the first embodiment according to FIGS. 1 to 4, but some forms less heavily ⁇ . It can be seen that there the drawstring section 84 is formed only by two parallel between the coupling elements 50 and the intermediate coupling element 60 ⁇ arranged chain sections of pull tabs. Another difference of this coupling in comparison to the previously described couplings be ⁇ is that only four arm-like coupling projections 24i to 24 4 or 26i to 26 4 are provided. However, all coupling arms are coupled on both sides via connec ⁇ tion arrangements 42i to 42 8 torque transmitting, so that torque can be transmitted in two directions. This makes it possible to drive the two coupled via the coupling device of FIG. 11 shaft sections alternately in both directions of rotation. The above-described embodiments according to FIGS. 1 to 10 do not allow this or only conditionally.
- the coupling device according to the invention can be embodied in a variety of designs. What is essential is the arrangement of an intermediate coupling part 60 between the two coupling parts 12 and 16 and the corresponding torque-transmitting connection of the two coupling parts via the intermediate coupling part using the respective connecting assemblies 42.
- the elasticity to compensate for torsional vibrations arises in particular from the elasticity of the radially extending Wernere.
- the flexibility with respect to an offset compensation results from the decoupled arrangement of the two coupling parts and the substantially free mobility of the intermediate coupling part through the intermediary of the connection arrangements.
- the Y configuration of the connection arrangements allows a corresponding tensile stress of the tensile strand section 54.
- connection arrangements it is also possible to make all parts of the connection arrangements more solid, ie not elastic, so as to enable a corresponding offset compensation, but to make the damping properties less pronounced or to eliminate them altogether.
