(29) The closure 38 shown in FIG. 4 at the respective end regions 41-42, 43-44 of the ring segments 21, 22 comes into existence when the predefined contact surfaces 15, 58 of the outer wedge part 342 or 351 are in firm contact according to FIG. 4 in a positive fit with the contact surfaces 16, 59, which correspond to the contact surfaces 15, 58, of the inner wedge part 341, 352 according to FIG. 5a, 5b.

(30) FIG. 4 thereby shows a sectional illustration of the coupling ring 40 according to the invention, which ring can be joined together at the end regions 41, 42 and 43, 44 of the ring segments 21, 22, said end regions being indicated in FIG. 5 or FIG. 5a and FIG. 5b, and can be prestressed. The wedge packet ring 40 is illustrated as being completely divided, or completely separable, into the two one-piece ring segments 21, 22 thereof in FIGS. 5, 5a, 5b.

A shoulder screw (not shown) can also be used for the screw connection 201. The same thing applies, for example, to the apportioned securing element 35 with the wedge parts 352, 351 and with the sleeve 6 or only with the shoulder screw (not shown).

(59) Below, the coupling ring 40 according to the invention is described in the form of the wedge packet ring for the coupling 50 with the coupling 30 specified in the prior art, in combination with the two coupling parts 8, 9.

(60) The star arm face regions 4, 5 respectively belonging to a star 2, 3 and adapted to the securing elements 10, 11, 34, 35 of the wedge packet ring 40 each constitute end regions of the star arms 27, 28 extending out from a central region of the star 2, 3, wherein the end regions comprise a surface 29 directed towards the securing elements 10, 11, with which surface a contacting connection to the surface 31 on the wedge-shaped narrow end region 32 of the wedge-shaped securing element 10, 11, 34, 35 can be produced.

(63) By means of the screw connections 20, 201, a frictional fit is generally achieved between the wedge packet ring 40 and the coupling parts 8, 9, which frictional fit is supported by the positive fits (spring, groove). In general, there is a hybrid of a frictional fit and positive fit in the region of the connection between the wedge packet ring 40 and the two coupling parts 8, 9 assigned to the coupling 50. The securing elements comprising at least one of the fits are referred to as closure securing elements or closure part securing elements.

(66) The shapes of the securing elements 10, 11, 34, 35 are adapted to the shapes of the spring element 17 such that the vulcanization of the spring elements 17 to the securing elements 10, 11, 34, 35 can take place with the same quality for the one-piece ring segments 21, 22, 25, 26.

(67) By means of the screw connections 20, 201, the securing element 10 can be connected in an alternating manner, starting from a securing element 10 of the wedge packet ring 40, to the star arm face region 4 of the one star 2, and then the securing element 11 adjacent to the securing element 10 can be connected to the star arm face region 5 of the other star 3, which face region is adjacent to the star arm face region 4 of the one star 2, wherein subsequently a further securing element 10 is again connected to a further star arm face region 4 of the one star 2, and so on, so that the wedge packet ring 40 is radially screwed onto the intermeshed coupling parts 8, 9 at the inner ring region 36.

(68) The advantages of the elastic, segmented wedge packet ring 40 according to the invention with a tangential creation of prestress on the two coupling parts 8, 9 in the coupling 50 is a uniform displacement compensation created by the simultaneous vulcanization of all spring elements 17 onto the adjacent securing elements 10, 11, 34, 25 of the respective ring segments 25, 26, and in particular an elimination of an assembly apparatus for the uniform creation of prestress on the stars 2, 3 of the coupling parts 8, 9.

(69) The essence of the invention enables an attachment of a ring-segmented, two-piece or more wedge packet ring 40 composed of at least the two, each individually vulcanized ring segments 25, 26 by means of the solely radial screw connection 20, 201 onto the star arm face regions 4, 5 of the coupling stars 2, 3, which face regions are located below the securing elements 10, 11, 34, 35, embodied with radially directed threaded bores 14, and axially offset from the star centers. Additionally, the pronounced corresponding profiles 29, 31 support the fixing of the wedge packet ring 40 at the star arm face regions 4, 5 of the coupling parts 8, 9.

(70) Apart from this, the securing elements 10, 11, 34, 35 can be composed of solid material, in particular, can be embodied metallically or from another solid substance/matter/material.
