The disclosure relates to an apparatus for sealing shafts, the apparatus comprising at least one device for positioning at least one first sealing means and a second sealing means on a shaft in a specified manner. At least the first sealing means has a partly elastic wall region for restricting a fluid passage out of a first region, in which a fluid is provided, into a second region, from which the shaft is sealed by the first region. The wall region forms an opening through which the shaft is guided, the diameter of the opening being variable dependent on the diameter of the shaft, and the second sealing means lies over the first sealing means so as to contact same at least in some regions in order to seal the fluid passage. |

1. An apparatus for sealing shafts, the apparatus comprising:
a first sealing means, a second sealing means and a device for pre-determined positioning of the first sealing means and of the second sealing means on a shaft, at least the first sealing means having an at least partially elastic wall region for limiting passage of fluid from a first region, in which the fluid is providable, into a second region with respect to which the shaft is sealable off from the first region, wall region of the first sealing means forming an opening through which the shaft is passable, and having a diameter that can be changed dependent upon a diameter of the shaft, the second sealing means overlapping the first sealing means at least partially with contact for sealing off the passage of fluid, wherein the first sealing means and the second sealing means are in the form of press-formed lamellar discs or of press-formed sealing sleeves which have lamellae bent in an axial direction. |
