Abstract
Official abstract text for this publication.
A seal assembly having a sealing ring, including at least one dynamically stressed sealing lip ( 1 ) and a buffer seal ( 2 ), which is arranged adjacent to the sealing lip ( 1 ) at an axial distance ( 3 ) therefrom, wherein the buffer seal ( 2 ) is made of an electrically conductive material, and wherein the sealing lip ( 1 ) and the buffer seal ( 2 ) are adjacent to and in contact with a surface ( 5 ) to be sealed of a first machine element ( 6 ) to be sealed, wherein the first machine element ( 6 ) to be sealed is arranged adjacent to a second machine element ( 8 ) at a radial distance ( 7 ) therefrom, wherein the sealing ring ( 1 ) is arranged in the a gap ( 9 ) formed by the radial distance ( 7 ), wherein the first ( 6 ) and second machine elements ( 8 ) are in contact with the buffer seal ( 2 ) in an electrically conductive manner.
First claim
Opening claim text (preview).
The invention claimed is: 1. A sealing assembly, comprising at least one dynamically stressed sealing lip ( 1 ) and a buffer seal ( 2 ), which is formed as a separate member from the sealing lip and disposed adjacent to the sealing lip ( 1 ) at an axial distance ( 3 ) therefrom, wherein the buffer seal ( 2 ) is made of an electrically conductive material including a non-woven fabric. 2. The sealing assembly according to claim 1 , wherein the electrically conductive material of the buffer seal ( 2 ) includes PTFE. 3. The sealing assembly according to claim 1 , wherein the buffer seal ( 2 ) is embodied as circular. 4. The sealing assembly according to claim 1 , wherein the sealing lip ( 1 ) is made of an elastomeric material. 5. The sealing assembly according to claim 1 , wherein a dirt lip ( 4 ) is arranged axially between the sealing lip ( 1 ) and the buffer seal ( 2 ) within the axial distance ( 3 ). 6. The sealing assembly according to claim 5 , wherein the dirt lip ( 4 ) and the sealing lip ( 1 ) are embodied as transitioning into one another as a single integral piece and as materially uniform.
