Problems solved by technology

[0010] Care must be taken in this constructional design of the seal assembly: Gradual changes in the condition of the seal cannot be detected
Closing through the circuit only means: the seal is no longer usable and must be replaced immediately

Embodiment Construction

[0041] exist figure 1 An embodiment is shown in , as already disclosed in the earlier application mentioned above.

[0042] The sealing arrangement comprises a sealing ring 1 with a dynamically loaded sealing lip 2 which, with radial prestressing, tightly surrounds a surface 4 to be sealed of a mechanical part 3 to be sealed.

[0043] The surface 4 to be sealed is electrically conductive.

[0044] The sealing ring 1 comprises a core 5 which is surrounded by a cladding 7 in the region of its end faces 16 , 17 and on the side facing the surface 4 to be sealed.

[0045] The core 5 consists of an electrically conductive material 6 , while the cladding 7 consists of an electrically insulating material 8 .

[0046] A wear sensor 12 is shown schematically, which includes an electrical measuring device 13 for detecting the wear state of the sealing ring 1 .

[0047] Seen in the sectional illustration shown here, the cladding 7 has overall a constant material thickness 9 , 10 , 11 ....

Abstract

The invention relates to a sealing assembly comprising: a sealing ring (1) with at least one sealing lip (2) subjected to dynamic loads; a mechanical part (3) to be sealed with a surface (4) to be sealed, said The sealing surface is electrically conductive and is tightly surrounded by the sealing lip (2) with radial pretension, wherein the sealing ring (1) has a core (5) of electrically conductive material (6) and an electrical a cladding (7) of insulating material (8) having a material thickness (9, 10, 11), at least partially surrounding the core (5) and including said sealing lip; and a wear detector ( 12) The wear detector comprises an electrical measuring device (13) for detecting the wear condition of the sealing ring, wherein, viewed in section, the material thickness (9) of the sealing lip along the radial direction (14) is smaller than that of the packing The material thickness of the rest of the layer (10, 11). The invention also relates to a sealing ring.

Description

technical field [0001] The invention relates to a sealing assembly comprising: a sealing ring with at least one dynamically loaded sealing lip; a mechanical part to be sealed with a surface to be sealed, which is electrically conductive and Sealed with radial pretension by a sealing lip, wherein the sealing ring has a core of an electrically conductive material and a cladding of an electrically insulating material with a material thickness that encloses the core at least partially ground surrounding and including said sealing lip; and a wear detector including an electrical measurement device for detecting a wear condition of the seal ring. [0002] In addition, the present invention also relates to a sealing ring in the sealing assembly, as mentioned above. Background technique [0003] Such a sealing assembly and such a sealing ring are disclosed in the earlier application DE 10 2016 012 552.7. [0004] The electrically insulating cladding has a material thickness that i...
