Abstract

Claims (20)

1. An arrangement for producing an electrically conductive connection between a first machine element and a second machine element, comprising:

an electrically conductive disk which is secured to a supporting body, the electrically conductive disk comprising a non-woven impregnated with an electrically conductive material,

wherein the disk is provided with a bore for receiving the second machine element,

wherein two or more slots are introduced into the disk starting from a peripheral edge of the bore,

wherein one or more of the slots open into an expansion on a side facing radially away from the peripheral edge, and

wherein each expansion is circular and has a circumferential width that is greater than a circumferential distance between two radially extending edges delimiting a respective one of the one or more slots.

2. The arrangement according to claim 1 , wherein the slots extend in a radial direction.

3. The arrangement according to claim 1 , wherein the slots are evenly distributed over a circumference of the disk.

4. The arrangement according to claim 1 , wherein, when viewed over a circumference of the disk, every second slot opens into one of the one or more expansions.

5. The arrangement according to claim 4 , wherein every other slot does not open into an expansion.

6. The arrangement according to claim 4 , wherein the expansions are circular, and wherein a diameter of each of the expansions is greater than the distance between two edges delimiting the slot.

7. The arrangement according to claim 1 , wherein the disk is made of porous material.

8. The arrangement according to claim 1 , wherein the supporting body is configured to be electrically conductive.

9. The arrangement according to claim 1 , wherein the supporting body comprises an inner ring and an outer ring, and wherein the disk is secured between the inner ring and the outer ring.

10. The arrangement according to claim 1 , wherein the extension of the slots in a radial direction is between 25 percent and 75 percent of an extension of the disk from the bore to an outer edge of the disk.

11. The arrangement according to claim 10 , wherein the extension of the slots in a radial direction is at a midpoint of a radial extension of the disk from the bore to the outer edge of the disk.

12. The arrangement according to claim 1 , wherein each of the slots comprise inner edges that face each other and are spaced apart from each other.

13. The arrangement according to claim 1 , wherein every slot opens into one of the one or more expansions.

14. The arrangement according to claim 1 , wherein each expansion is configured to reduce a notch effect resulting from mechanical stress in the disk at a respective slot.

15. The arrangement according to claim 1 , wherein the conductive material with which the disk is impregnated completely penetrates the disk.
