Abstract

Sealing element for producing an electrically conductive connection between a first machine element and a second machine element, comprising at least one disc-shaped conducting element and a support ring, the support ring comprising an axial flange and a radial flanged, the conducting element being formed from an electrically conductive foil, and the conducting element being secured at least in sections along the axial flange between the support ring and the second machine element.

First claim

What is claimed is:

1. A sealing element for producing an electrically conductive connection between a first machine element and a second machine element, comprising at least one disc-shaped conducting element, a first support ring and an electrically conductive second support ring, the first support ring comprising a first axial flange and a first radial flange, the second support ring comprising a second axial flange and a second radial flange wherein the second axial flange is in contact with the second machine element, the conducting element secured between the first support ring and the second support ring and in contact with and supported by the radial flange of the first support ring and being formed from an electrically conductive foil, the conducting element being secured between the first axial flange and the second axial flange, and a pressing element formed of elastomeric material, the pressing element securing the conducting element between the first support ring and the second machine element by means of elastic deformation.

2. The sealing element according to claim 1 , wherein a radial shaft sealing ring is arranged on the first support ring, the radial shaft sealing ring forming the pressing element.

3. The sealing element according to claim 1 , wherein an elastomer track is arranged on the first support ring, the elastomer track forming the pressing element.

4. The sealing element of claim 1 , wherein the conducting element comprises an axially extending section positioned on the outer peripheral side of the first axial flange of the first support ring.

5. The sealing element of claim 4 , wherein the pressing element is disposed between the axially extending section and the first axial flange.

6. The sealing element of claim 1 , where in the conducting element comprises at least one of aluminum and copper.

7. A sealing element for producing an electrically conductive connection between a first machine element and a second machine element, comprising a first support ring, the first support ring comprising a first axial flange and a first radial flange, a second electrically conductive support ring comprising a second axial flange and a second radial flange, at least one conducting element formed from an electrically conductive material and comprising a radial body portion and an axial section, the axial section of the conducting element extending an axial distance along the first axial flange of the first support ring less than the axial length of the first axial flange of the first support ring, and a pressing element disposed between the first axial flange of the first support ring and the axial section of the conducting element to frictionally secure the conducting element between the first axial flange of the first support ring and the second axial flange of the second support ring, with the second axial flange of the second support ring in contact with the second machine element and the radial body portion of the conducting element in contact with at least one of the first radial flange of the first support ring and the second radial flange of the second support ring.

8. The sealing element of claim 7 , wherein the radial body portion of the conducting element is disc-shaped.

9. The sealing element of claim 7 , wherein the first axial flange of the first support ring comprises a step that defines a first axial portion and a second axial portion disposed at different radial distances from the first machine element.
