Abstract

A multi-disk coupling includes a first flange, a second flange, and a disk pack via which the first and second flanges are connected to one another in a torque-transmitting manner. A first fastener connects the multi-disk to one of the first and second flanges, and a second fastener is detachably connected to the first fastener and connected to the multi-disk via a material-fit connection.

First claim

What is claimed is:

1. A multi-disk coupling, comprising:
a first flange;
a second flange;
a disk pack via which the first and second flanges are connected to one another in a torque-transmitting manner;
a first fastener connecting the disk pack to the first flange; and
a second fastener detachably connected to the first fastener and connected to the disk pack via a material-fit connection,
wherein the disk pack is configured at least in a region of the second fastener devoid of any recess.

2. The multi-disk coupling of claim 1 , wherein the first fastener is a member selected from the group consisting of a screw, bolt, threaded bolt, and fitted bolt, and the second fastener is a member selected from the group consisting of a nut and a welded nut.

3. The multi-disk coupling of claim 1 , wherein the material-fit connection is embodied as a welded connection, solder connection, hard solder connection or adhesion.

4. The multi-disk coupling of claim 1 , wherein the material-fit connection is established by electron beam welding or laser welding.

5. The multi-disk coupling of claim 1 , wherein the second flange is detachably connected to the disk pack via the first fastener.

6. The multi-disk coupling of claim 1 , further comprising a further one of said second fastener arranged in adjacent relationship to the second fastener and connected with a material fit to the disk pack, said second fasteners being spaced from one another by a distance which corresponds to a free disk length.

7. The multi-disk coupling of claim 1 , further comprising a spacer arranged between the second fastener and the disk pack, said material-fit connection being established between the disk pack and the spacer.

8. The multi-disk coupling of claim 1 , wherein the material-fit connection is established directly between the second fastener and the disk pack.

9. The multi-disk coupling of claim 1 , wherein the multi-disk coupling has a surface-specific power density of 100 MW/m 2 to 400 MW/m 2 .

10. The multi-disk coupling of claim 1 , wherein the multi-disk coupling has a surface-specific power density of 150 MW/m 2 to 350 MW/m 2 .

11. The multi-disk coupling of claim 1 , wherein the multi-disk coupling has a surface-specific power density of 160 MW/m 2 to 280 MW/m 2 .

12. The multi-disk coupling of claim 1 , wherein the first fastener is configured to receive a transverse force.

13. The multi-disk coupling of claim 1 , wherein the disk pack has a maximum radial width which corresponds to 1.0 to 1.8 times a minimal radial width of the disk pack.

14. The multi-disk coupling of claim 1 , wherein the disk pack has a maximum radial width which corresponds to 1.0 to 1.5 times a minimal radial width of the disk pack.

15. The multi-disk coupling of claim 1 , wherein the disk pack has a maximum radial width which corresponds to 1.0 to 1.2 times a minimal radial width of the disk pack.

16. The multi-disk coupling of claim 1 , wherein the disk pack has a substantially continuous, constant thickness.

17. The multi-disk coupling of claim 1 , further comprising a further one of said second fastener arranged in adjacent relationship to the second fastener, said disk pack having a tensile load-bearing section extending between the adjacent second fastener and further second fastener and configured with respect to a connecting line in symmetry between the adjacent second fastener and further second fastener.

18. The multi-disk coupling of claim 1 , wherein the material-fit connection is a punctiform connection between the second fastener and the disk pack.

19. The multi-disk coupling of claim 1 , wherein the material-fit connection extends all around the second fastener.

20. An industrial application, comprising:
an output unit;
a drive unit; and
a multi-disk coupling connecting the drive unit to the output unit in a torque-transmitting manner, said multi-disk coupling comprising a first flange, a second flange, a disk pack via which the first and second flanges are connected to one another in a torque-transmitting manner, a first fastener connecting the disk pack to the first flange, and a second fastener detachably connected to the first fastener and connected to the disk pack via a material-fit connection, wherein the disk pack is configured at least in a region of the second fastener devoid of any recess.
