Abstract

Official abstract text for this publication.

Sealing element for producing an electrically conductive connection between a first machine element and a second machine element, including at least one sealing disc and a support ring, the support ring comprising an axial flange and a radial flange, the sealing disc being formed from an electrically conductive non-woven fabric, and the sealing disc being secured at least in sections along the axial flange by means of a clamping connection between the support ring and the second machine element.

First claim

Opening claim text (preview).

What is claimed is: 1. A sealing element for producing an electrically conductive connection between a first machine element and a second machine element, including at least one sealing disc and a support ring, the support ring comprising an axial flange and a radial flange, the sealing disc being formed from an electrically conductive non-woven fabric, and the sealing disc being secured at least in sections along the axial flange by means of a clamping connection between the support ring and the second machine element. 2. The sealing element as claimed in claim 1 , wherein in the section in which the sealing disc is secured between the support ring and the second machine element, the sealing disc is compressed between 5% to 50% of the initial thickness. 3. The sealing element as claimed in claim 1 , wherein the support ring includes an inner ring and an outer ring, wherein the sealing disc is secured between the inner ring and the outer ring. 4. The sealing element as claimed in claim 3 , wherein the support ring includes at least one intermediate ring, wherein a first sealing disc is secured between the inner ring and the intermediate ring and at least one second sealing disc is secured between the intermediate ring and the outer ring. 5. The sealing element as claimed in claim 4 , wherein the outer ring is electrically conductive. 6. The sealing element as claimed in claim 5 , wherein the first sealing disc and the second sealing disc consist of mutually different materials. 7. The sealing element as claimed in claim 4 , wherein the inner ring and/or the intermediate ring are electrically conductive. 8. The sealing element as claimed in claim 1 , wherein a radial shaft sealing ring is arranged on the inner ring. 9. The sealing element as claimed in claim 1 , wherein an elastomer track is arranged on the inner ring. 10. The sealing element as claimed in claim 9 , wherein the elastomer track forms a receptacle for the sealing disc. 11. The sealing element as claimed in claim 1 , wherein the sealing disc comprises electrically conductive particles. 12. The sealing element as claimed in claim 1 , wherein the sealing disc formed from non-woven fabric is provided with a PTFE dispersion.
