する。The coupling elements are preferably made of so-called prepregs which are compressed in layers. In this case, pre-cut prepregs may be stacked in the bonding range or an additional prepreg layer may be placed in the bonding range to make the bonding range more rigid than the deformation range. Due to additional layers or laps in the mounting area, and possibly even stronger compression in the deformation area, these areas differ in thickness in the finished joint element. The abdominal deformation region preferably transitions into the connection region at right angles to its longitudinal axis. This transition is preferably continuous in terms of thickness variation. As described in DE-A-40 33 596, it is advantageous for the load in the deformation range if the mounting holes are displaced radially inward with respect to the intersection of the central axes of the abdominal deformation range. As described in DE-A-40 33 594, the coupling element can advantageously be formed circumferentially in the form of an integral connecting element with each second mounting area. In all other respects, the contents of the above publications are referred to as far as it is permitted.

が著しく減退する。It has been found that a shaft coupling element of the above type is suitable for transmitting high torques. The power transmission between the shaft coupling element and the generally screwed connecting shaft, in particular its shaft flange, is ideally achieved by a friction fit between the surface of the connecting area and the connecting element. Alongside that, the form-fitting of the connecting element in the through hole can also take up part of the power transmission. Connection range problems can arise when a particularly high torque is generated in a joint of the type described, which the joint can basically absorb. When the torque applied to the coupling element exceeds a certain value, the friction fit is no longer sufficient to transfer power at the surface of the connecting area. The part of the shaft coupling element between the flange of the connecting shaft and the mounting element, in particular the washer of the screw, undergoes elastic elongation which can no longer be prevented by the friction fit. This causes a relative movement of the parts that are fixed to each other, but this movement does not necessarily occur equally in all mounting areas.
However, when the torque to be transmitted continues to decrease, the fixing force of the attachment means prevents the elastic deformation from being reduced, so that the reverse deformation does not occur completely. When the deformation is realized, the deformation that increases the distance between both through holes remains at the end of the deformation range that is loaded during the deformation. Due to the rigidity of the shaft flange of the connecting shaft, this residual deformation cannot be compensated for even by suitable flexing of the rigid part. The result of this process can be seen in the fact that one part of the abdomen bulges significantly when both connecting shafts are simultaneously coaxially aligned and the shaft coupling continues to relax. If the shaft coupling element is operated in this state, its life will be significantly reduced.

ない。According to a first solution to this problem, the coupling area is provided with a material reinforcing portion concentric with the through hole and having a conical surface, and the apex of the opening angle corresponds to the mounting area. On the outside, on the axis of the through hole, there is an internal conical recess in the connecting means for transmitting power between the connecting means for the mounting range and the connecting means for the conical surface of the material reinforcement. , Or by providing an additional annular plate having an internal conical recessed recess whose surface is complementary to the conical surface of the material reinforcement. In this case the taper angle α 1 should preferably be between 12 ° and 30 °.
Instead of a conical surface, a slightly spherical shape, which is slightly different from the exact conical shape, can be used as well. In this case, according to the invention, instead of a pure friction fit, an additional form fit appears in the surface area. Due to the fixing force such as a screw in the section passing through the axis of the mounting hole in the direction of the acting tensile force, a component of the force acting against this tensile force in the bending range is directed toward the axis and is generated on the surface of the mounting range. Therefore, a much higher pulling force than in the prior art is required to allow a sliding movement between the conical surface of the mounting area and the annular plate in the direction of said pulling force. Nevertheless, if such sliding occurs, for example when μ = 0.2, then preferably a taper suitable for causing a complete reverse deformation on the basis of the component of said force generated by the fixing force of the mounting element. The angle α 1 is> 11 °. For manufacturing engineering reasons, the taper angle α 1 preferably does not exceed 30 °.

る。According to a second solution to the above-mentioned problem, the coupling area is provided with a material reinforcing portion concentric with the through hole and having a cylindrical peripheral surface, and the attachment area connecting means and the conical surface of the material reinforcing portion are provided. To solve this problem, a groove is provided in the connecting means or an additional annular plate having a groove having an opening diameter corresponding to the cylindrical peripheral surface is provided for transmitting power to and from the connecting means. It In this case, the connecting element or the groove of the annular plate can have an inner cylindrical or inner conical shape on the peripheral surface. Here too, according to the invention, instead of a pure friction fit, an almost additional form fit appears in the surface area of the material reinforcement. Sliding movements between the mounting area and the connecting element or the tubular surface of the annular plate are possible only by breaking the connecting area, i.e. by shearing the material reinforcement. This requires extremely high forces that are unpredictable even under normal operating peak loads.

The annular plate has a pure radial boundary surface on the side of the connecting shaft, i.e. on its flange side. Besides the screws already pointed out, rivets can also be provided as mounting elements. Another advantageous effect is that when the mounting element is fixed axially, the material reinforcement is elastically deformed and the through hole becomes smaller, already at this point, even if the tolerance is large, there is a shape between the mounting element and the through hole. The point is that mating is inevitably realized. This action occurs in cooperation with the connecting element or the internal conical recess or groove of the annular plate when the material reinforcement has a conical surface and a cylindrical peripheral surface.

In this case, the axial fixing is effected by a single annular plate 7a and a connecting element 7c, both of which have internal conical mating surfaces 9a, 9b complementary to the conical surfaces 8a, 8b of the material reinforcement. α 1 is also the taper angle between the surfaces 8a and 8b of the material reinforcing portion and the plane perpendicular to the axis of the through hole. Axial fixing of parts is performed by a screw / nut joint 10. In this case, the diameter of the through hole 4 corresponds to the diameter of the through hole of the annular plate and the connecting element when the annular plate and the connecting element are already fixed in the axial direction. Both substantially match the diameter of the screw. That is, here, in the unfixed departure state, the through hole 4

と弛緩復帰すると完全に生じる。FIG. 15 shows an undeformed shaft coupling element. All the deformation ranges between the dot-shaped attachment points have the same starting length l 0 . In FIG. 16 the same elements are shown under high torque, the fixing points of each connecting element forming the same angle with each other, all on the same reference pitch circle. At that time, the first deformation range is expanded, that is, the length l> l 0 is set, while the second deformation range between them is compressed, that is, the length l <l 0 is set.
There is. Compression may in this case be associated with the deformed abdomen bulging from its neutral plane. If the flange arm represented by the triangle of the second connecting element is firmly fixed to the mounting location as intended by the subject of the invention, the deformation shown in FIG. Completely upon relaxation and return.

がその出発状態に戻らなくなる。However, in the shaft coupling element according to the prior art, along with the above-mentioned elongation and compression, the sliding of the connecting element with respect to the mounting range partially occurs, and the connecting section shown in FIG. 16 is the distance of the flange arm of the mounting location. However, it is not the center point of the through hole of the shaft coupling element. As a result of such sliding, the shaft coupling element does not return to its starting state when the torque is relaxed.

それらの平面で反っているのが示してある。In the example shown in FIG. 17, the flange arm of the second connecting element is radially flexible. Here, reverse deformation of the deformation range compressed in advance to the starting length L 0 occurs, and the deformation range expanded in advance is forcibly expanded by sliding the attachment point. In the reverse deformation shown in FIG. 18, the mounting location is radial rigid both in the flange arm of the first connecting element and in the flange arm of the second connecting element, that is, the mounting point is on the same reference pitch circle even after torque relaxation. It happens sometimes. Here, when the deformation range is expanded in advance, the swelling effect also occurs due to the sliding of the attachment point. In this case, the opposing force generated is large, and the bulging effect in the range shortened in advance cannot be completely restored. The cross section AA shows that both areas are warped in their plane.
