Abstract
Official abstract text for this publication.
A ballast seal for a sealing ring includes: a substantially annular potential equalization ring made of an electrically-conductive material and which can be brought into contact in a sealing manner with a surface to be sealed of a machine element to be sealed; and at least one shielding ring made of a soft magnetic material so as to shield against electromagnetic interfering waves.
First claim
Opening claim text (preview).
What is claimed is: 1. A ballast seal for a sealing ring, comprising: a substantially annular potential equalization ring comprising an electrically-conductive material and which can be brought into contact in a sealing manner with a surface to be sealed of a machine element to be sealed; and at least one shielding ring comprising a soft magnetic material so as to be configured to shield against electromagnetic interfering waves, the at least one shielding ring being electrically non-conductive. 2. The ballast seal according to claim 1 , wherein the potential equalization ring and the shielding ring are connected to one another and form a pre-assemblable first unit. 3. The ballast seal according to claim 1 , wherein the shielding ring comprises a ferrite ring. 4. The ballast seal according to claim 1 , wherein the at least one shielding ring comprises at least two shielding rings, the at least two shielding rings being arranged in a functional series connection. 5. The ballast seal according to claim 4 , wherein the at least two shielding rings are arranged to be adjacent to one another in an axial direction. 6. The ballast seal according to claim 4 , wherein the at least two shielding rings form a pre-assemblable second unit. 7. The ballast seal according to claim 1 , wherein the potential equalization ring comprises an air-permeable and electrically-conductive non-woven ring. 8. A sealing arrangement, comprising: the ballast seal according to claim 1 ; and a sealing ring, wherein the ballast seal is arranged on a side axially facing away from a space to be sealed, on a side of the sealing ring facing the environment. 9. The sealing arrangement according to claim 8 , wherein the ballast seal and the sealing ring form a pre-assemblable third unit.
