Embodiment Construction

[0039] exist figure 1 An embodiment is shown in , as already disclosed in the earlier application mentioned above.

[0040]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.

[0041] The surface 4 to be sealed is electrically conductive.

[0042] 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.

[0043] The core 5 consists of an electrically conductive material 6 , while the cladding 7 consists of an electrically insulating material 8 .

[0044] A wear sensor 12 is shown schematically, which includes an electrical measuring device 13 for detecting the wear state of the sealing ring 1 .

[0045] Seen in the sectional illustration shown here, the cladding 7 has overall a constant material thickness 9 , 10 , 11 . ...

Abstract

Sealing arrangement, comprising a sealing ring (1) having at least one dynamically loaded sealing lip (2), and a machine element (3) to be sealed that has a surface (4) to be sealed, which surface iselectrically conductive and surrounded by the sealing lip (2) in a radially prestressingly sealing manner, the sealing ring (1) comprising a core (5) made of an electrically conductive material (6) and a casing (7) made of an electrically insulating material (8), the casing (7) having a material thickness (9, 10, 11), surrounding the core (5) at least in part and comprising the sealing lip (2), said sealing arrangement comprising a wear detector (12), which has an electric measurement device (13) for detecting the state of wear of the sealing ring (1), wherein, when viewed in section, the material thickness (9) of the sealing lip (2) is smaller in the radial direction (14) than the material thickness (10, 11) of the remainder of the casing (7).

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 a seal 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 is cons...
