Embodiment Construction

[0020] exist figure 1 A sealing device 1 can be seen in the figure, which seals off a first region 2 (air side) of a mechanical component 3 in the form of a shaft from a second region 4 (oil side). For this purpose, the sealing device 1 has a sealing element 5 which (designed as a radial shaft seal) has two sealing lips 8 and 9 which are frictionally resting against the shaft 3 .

[0021] The same applies to press figure 2 In the embodiment of the present invention, the sealing device 1 is here designed as a labyrinth sealing device, so that a gap 6 remains between the sealing element 5 and the shaft 3, which gap should prevent the ingress of moisture or dirt.

[0022] In order to better prevent the ingress of moisture, especially water and dirt, the invention provides that, in both embodiments, the sealing element 5 and the mechanical part 3 are provided or coated with a Materials with superhydrophobic properties7. This means that the material is applied rotationally symm...

Abstract

The invention relates to a seal assembly (1) which seals off a first region (2) of a machine part (3) with respect to a second region (4) of the machine part (3), wherein the seal assembly (1) comprises at least one seal element (5) which is in contact with the machine part (3) or a component connected thereto or which runs on the machine part (3) or on the component connected thereto, forming a gap (6). In order to protect the seal arrangement better against penetrating moisture, the invention provides for the seal element (5) and / or the machine part (3) and / or the component connected to the machine part (3) to be provided or coated in the region of the seal element (5) with a material (7) which has super-hydrophobic properties.

Description

technical field [0001] The invention relates to a sealing device which seals a first region of a mechanical part against a second region of the mechanical part, wherein the sealing device has at least one sealing element which is connected to the mechanical part or to the mechanical part The connected parts contact or the sealing element extends, forming a gap, on the mechanical part or on a part connected to the mechanical part. Background technique [0002] Sealing arrangements of this type are well known. The seal acts both as a frictional seal (for example a radial shaft sealing ring) and as a non-frictional seal (labyrinth seal), whereby sealing of the component region can be ensured. [0003] Although there are corresponding applications, it is not always possible to prevent the penetration of moisture and dirt into the area to be sealed. Due to the risk of corrosion caused by the ingress of water or the contamination of the lubricant (lubricating oil or grease), thi...
