Abstract

A coupling includes a plurality of laminations forming a lamination package and having lamination holes arranged flush to form an assembly opening, a ring, and a bush accommodated in the assembly opening and having a first end area connected to the ring via a form-fit connection.

First claim

What is claimed is:

1. A coupling, comprising:
a plurality of laminations forming a lamination package and having lamination holes arranged so as to be in alignment with an assembly opening;
a ring;
a bush made of a metallic material and received in the assembly opening and having a first end region connected to the ring via a releasable form-fit connection in an axial direction, wherein a first latching groove is embodied in a first end area of the bush and a second latching groove is embodied on an inner surface of the ring; and
an intermediate ring arranged in an assembled state of the coupling in the first latching groove and the second latching groove opposite the first latching groove, with the intermediate ring establishing a non-positive connection and the releasable form fit connection between the bush and the ring.

2. The coupling of claim 1 , wherein the releasable form-fit connection between the bush and the ring is established by a restoring force of the intermediate ring exerted on the inner surface of the ring and the first end region of the bush.

3. The coupling of claim 1 , wherein the non-positive connection is established by the restoring force produced by the intermediate ring.

4. The coupling of claim 1 , wherein the intermediate ring produces an indirect form fit between the ring and the bush.

5. The coupling of claim 1 , wherein the intermediate ring is made of a metallic material or plastic.

6. The coupling of claim 1 , wherein the bush has a collar on one side for support of the bush against the lamination package.

7. The coupling of claim 1 , wherein the ring is connected to the bush via the form-fit connection by applying an assembly force of up to 15 kN.

8. A shaft arrangement, comprising:
a first shaft;
a second shaft; and
a coupling connecting the first shaft to the second shaft for transmission of torque, said coupling configured as set forth in claim 1 .

9. An industrial application, comprising:
a drive unit including a first shaft;
a mechanical application including a second shaft; and
a coupling connecting the first shaft of the drive unit and the second shaft of the mechanical application to one another for transmission of torque, said coupling being configured as set forth in claim 1 .

10. A wind power plant, comprising:
a generator;
a drive train including a rotor shaft in driving relationship to the generator and a coupling connecting the rotor shaft to a shaft of the generator for transmission of torque, said coupling being configured a set forth in claim 1 ; and
a rotor connected to the rotor shaft.

11. The coupling of claim 1 , wherein the ring is connected to the bush via the form-fit connection by applying an assembly force of up to 10 k.

12. The coupling of claim 1 , wherein the ring is connected to the bush via the form-fit connection by applying an assembly force of up to 8 kN.

13. The coupling of claim 1 , wherein the ring is connected to the bush via the form-fit connection by applying an assembly force of up 6.5 kN.

14. A method for manufacturing a coupling, comprising:
forming a lamination package with a plurality of assembly openings;
inserting a bush made of a metallic material into an assembly opening of the lamination package;
placing an intermediate ring in a first latching groove is embodied in a first end area of the bush or a second latching groove embodied on an inner surface of a ring; and
connecting the bush to the ring by pressing the ring onto the bush such that the intermediate ring is located in the first latching groove and the second latching groove opposite to the first latching groove in an assembled state of the coupling, to thereby establish a releasable form-fit and non-positive connection in an axial direction between the bush and the ring.

15. The method of claim 14 , wherein the rings and the bushes are connected essentially at a same time.
